Item 3. Key Information

Risk Factors

Risks Relating to Our Company and our Operations

We are controlled by the State of Paraná, the policies and priorities of which directly affect our operations and may conflict with the interests of our investors.

We are controlled by the State of Paraná, which holds 58.6 % of our outstanding common voting shares as of the date of this annual report, and whose interests may differ from other shareholders. As a major shareholder, the State of Paraná has the power to control all of our operations, including the power to elect a majority of the members of our Board of Directors and determine the outcome of any action requiring common shareholder approval, including transactions with related parties and corporate reorganizations.

As our operations have an important impact on the commercial and industrial development of the State of Paraná, the State of Paraná may use its status as our controlling shareholder to decide whether we should engage in certain activities and make certain investments aimed, principally, to promote its public policies or social objectives and not necessarily to meet the objective of improving our business and/or operational results. Further, proceedings involving the State of Paraná may affect its controlling shareholder position and, therefore, may impact our capital structure.

We are involved in several lawsuits that could have a material adverse effect on our business if their outcome is unfavorable to us.

We are the defendant in several legal proceedings, mainly relating to civil, administrative, labor and tax claims. The outcome of these proceedings is uncertain and, if determined against us, may result in obligations that could materially affect our results of operations. On December 31, 2020, our provisions for probable (more likely than not) and reasonably estimated losses were R$1,555.7 million. For additional information, see “Item 8. Financial Information–A. Consolidated Financial Information–Legal Proceedings”.

We are subject to limitations regarding the amount and use of public sector financing, which could prevent us from obtaining financing and implementing our investment program.

Our current budget anticipates capital expenditures for expansion, modernization, research, infrastructure and environmental projects of approximately R$1,902.7 million in 2021. As a state-controlled company, we are subject to Brazilian Central Bank Resolution no. 4,589/2017(Resolução nº 4,589/2017 do Banco Central do Brasil), which defines the limit of exposure and the annual global limit of credit to public sector entities to be observed by financial institutions and other institutions authorized to operate by the Brazilian Central Bank. The annual global limit that can be contracted in credit operations, with and without guarantee of the Union, by the bodies and entities of the public sector with the financial institutions and other institutions authorized to operate by the Brazilian Central Bank is defined by the National Monetary Council by means of inclusion of an annex to Brazilian Central Bank Resolution no. 4,589/2017, establishing, until the end of each fiscal year, the limit for the following year. The maximum amounts defined for the 2021 financial year are up to R$9.0 billion for Union guaranteed operations and up to R$11.0 billion for operations without Union guarantee. Although theses limits have recently increased, as a result of these limits, we may have difficulty in obtaining financing from financial institutions and other institutions authorized to operate by the Brazilian Central Bank, which could create difficulties in the implementation of our investment program. Additionally, some of our concession contracts have provisions that limit our permitted level of indebtedness, which could also affect our ability to obtain necessary financing. Furthermore, the requirements and other criteria adopted by financial institutions when approving new financing transactions may be related to certain Brazilian macroeconomic scenarios, as well as to our financial indicators, such as our indebtedness levels and other indicators usually considered by financial institutions in their credit risk assessments. We cannot ensure you that these requirements and criteria will be met. As a result of these regulations and provisions, our capacity to incur debt from certain sources is limited, which could negatively affect the implementation of our investment program.

4

Failures in our cybersecurity controls or unauthorized disclosure of information, as well as failure to comply with existing data privacy and data security laws may adversely affect our business and reputation. We have suffered cyber-attacks in the past leading to the unavailability of part of our systems.

We collect, store, process and use various confidential information related to our business and operations. In our ordinary course of business, we also collect and store personal data of our customers in our data centers located at our own premises.

Despite our cybersecurity controls, information technology and infrastructure (solarwinds), in the past we have been and in the future we may be vulnerable to failures whether caused by technical failures, negligence, accident or cyber-attacks. Those failures may result in disclosure or theft of sensitive information, loss of data integrity, misappropriation of funds and disruptions to or interruption in our business operations. For more information on cyber-attacks we suffered, see “Item 4. Information on the Company – Recent Developments.”

We are subject to the Brazilian Federal Law No. 13,709/2018 (Lei Geral de Proteção de Dados Pessoais, or the “LGPD”) that sets forth the legal framework to be observed by companies in the processing of personal data, which entered into effect on September 18, 2020, but its government penalties will only be enforceable from August 1, 2021, pursuant to Law No. 14,010/2020. As a result of any violations of this statute, including any leakage of personal data, beginning in August 2021, we may be subject to penalties, such as (i) a warning, with a deadline for taking corrective measures; (ii) a simple fine of up to 2% of our revenue in Brazil, limited to R$50 million for an infraction; (iii) a daily fine, limited to R$50 million for an infraction; (iv) disclosure of the infraction after duly proven; and (v) elimination of the personal data to which the violation refers. Also, any security incident involving personal data could damage our reputation, which could have an adverse effect on us, our business and our results of operations. Although the government sanctions are not yet in force, civil and criminal legal sanctions can be applied in case of violation of the LGPD’s provisions.

We have engaged an external consulting firm to assist us in adapting our internal controls to the new rules on data protection (especially the LGPD). As cyber threats continue to evolve, we may be required to expend additional resources to continue to modify or enhance protective measures or to investigate and remediate any security vulnerabilities that are discovered in the future.

The construction and expansion of our transmission and power generation projects involve significant risks that may have an adverse effect on us

Our activities related to the development of transmission and generation projects depend on the consent of third parties over which we have no control. In addition, project development is subject to environmental, engineering and construction risks that can lead to cost overruns, delays and other impediments to timely complete within a project’s budget. We cannot assure you that we will (i) obtain all required permits and approvals for our projects, (ii) secure private sector partners for any of our projects, or (iii) obtain adequate financing for our projects or that financing will be available on a non-recourse basis to us. If we are unable to complete a project or such project is delayed, this may decrease our expected financial return from the project, which may lead to impairment. As a consequence, our costs may increase or we may fail to achieve the revenues planned in connection with such expansion projects, which may have an adverse effect on our financial condition and results of operations.

We are largely dependent upon the economy of the State of Paraná.

The distribution market for the majority of our sales of electricity is located in the State of Paraná. Although a more competitive market involving possible sales to customers outside Paraná might develop in the future, our business depends and is expected to continue to depend to a very large extent on the economic conditions of Paraná.

The weak economic growth of Brazil in recent years led to the reduction of energy consumption in the State of Paraná and in Brazil as a whole, resulting in leftover energy in the interconnected system, consequently reducing (i) short-term prices and (ii) prices negotiated in the Free Market. At the same time, prices in the regulated market have risen steadily as a result of supply deficiencies on the part of contracted energy by distributors and high prices in the short-term market in previous years. As a result, consumers consistently migrated into the Free Market and, therefore, the distributors’ captive market suffered a reduction since 2018. We cannot assure you that economic conditions in Paraná will be favorable to us in the future.

5

Further, an increase in electricity prices, combined with poor economic performance in the State of Paraná, would affect the ability of some of our distributions customers to pay amounts owed to us. As of December 31, 2020, our past due receivables with Final Customers were approximately R$643.1 million in the aggregate and our allowance for doubtful accounts related to these receivables was R$212.3 million. See Note 7 to our audited consolidated financial statements.

In addition, in the event of an economic recession combined with high energy prices, the number of our distribution customers connecting illegally to our distribution grid may increase, which would then reduce our revenue from electricity sales to Final Customers. Energy we lose as a result of these illegal connections is considered a commercial loss (non-technical), and we may incur regulatory penalties if our commercial losses exceed certain established regulatory thresholds calculated by ANEEL. If ANEEL determines that we were not efficient in inspecting and controlling the non-technical losses in the distribution grid, the agency may limit the transfer of such losses to the Final Customers.

Disruptions in the operation of, or deterioration of the quality of, our services, or those of our subsidiaries, could have an adverse effect on our business, financial condition and results of operations.

The operation of complex electricity generation, transmission and distribution systems and networks involves various risks, such as operational setbacks and unexpected interruptions, caused by accidents, breakdown or failure of equipment or processes, performance below expected levels of availability and efficiency of assets, or disasters (such as explosions, fires, natural phenomena, landslides, sabotage, vandalism, and similar events). In addition, operational decisions by authorities responsible for the electricity network, environment matters, operations and other issues affecting the electricity generation, transmission or distribution could have an adverse effect on the performance and profitability of the operations of our generation, transmission and distribution systems. If these issues occurred, our insurance may be insufficient to wholly account for the costs and losses that we may incur as a result of the damages caused to our assets, or due to outages.

Further, the revenues that our subsidiaries generate from establishing, operating and maintaining their facilities are related to the availability of equipment and assets, and to the quality of the services (continuity and service in accordance with levels demanded by regulations). Under the related concession contracts, we and our subsidiaries are subject to: (i) a reduction of the distributor revenue as a result of the reduction of the so-called “Portion B” allocation in the revenue calculation formula; (ii) a reduction of the Permitted Annual Revenue - APR (Receita Anual Permitida, or RAP), for the transmission companies; (iii) the effects of the Availability Factor (Fator de Disponibilidade, or FID) and the offtake guarantee levels for the generation facilities; and (iv) the application of penalties and payment of compensation amounts, depending on the scope, severity and duration of non-availability of the services and equipment. Under Brazilian Law, we are strictly liable for direct and indirect damages resulting from the inadequate supply of electricity such as abrupt interruptions arising from the generation, transmission or distribution systems. Therefore, outages or stoppages in our generation, transmission and distribution facilities, or in substations or networks, may cause a material adverse effect on our business, financial situation and results of operations.

We are subject to risks related to social and environmental impacts of our projects.

The construction and operation of our assets may modify the ecosystem, particularly the natural state of the water resources and of the vegetation of the flooded river basin in the case of Hydroelectric Power Plants. Our projects may cause direct and indirect impacts in the local communities, such as housing displacement. Moreover, they may affect the economic outputs of the local communities, lead to the loss of cultural identity or increase the demand for government services. In these eventualities, we may implement specific plans in order to minimize and mitigate those impacts.

6

Failures in dams under our responsibility may cause serious damages to the affected communities, to our results and to our reputation.

Dams are important infrastructures to our business, and are fundamental components of our Hydroelectric Power Plants for the purposes of diking and storing water, accounting for the majority of our energy generation capacity. However, in any dam, there is an intrinsic risk of ruptures caused by different internal or external factors. Therefore, we are subject to the risk of a dam failure that could have repercussions much greater than just the loss of hydroelectric power generation capacity. A dam failure may result in economic, social, regulatory and environmental damages and potential loss of human life in the communities downstream from the dams, which may have a material adverse effect in the image, business, operational results and financial conditions of the Company.

Our governance, compliance and internal controls may fail to prevent breaches of legal, regulatory, ethical or governance standards.

We are required to comply with a wide range of laws and regulations, including anti-corruption , anti-money laundering and related laws and regulations. Although we have a range of internal policies and controls, we may be subject to breaches of those internal policies and controls and to instances of fraudulent behavior, corrupt practices and dishonesty by our directors, officers, employees, contractors or other agents that we may not timely identify or prevent.

Further, we have a large number contracts with suppliers with wide distribution and outsourcing of the production chains and we are not able to control all possible irregularities or to ensure that our selection processes will be sufficient to avoid situations where our suppliers have problems related to compliance with applicable law, sustainability or outsourcing of the production chain under inadequate safety conditions.

These risks are increased by the fact that our portfolio includes affiliated companies, such as special purpose companies, some of which we do not hold a controlling interest in.

Although we have an integrity program with timely updates and a robust process for investigating complaints, our systems may not be effective in all circumstances. Any failure in our capacity to prevent or detect noncompliance with the applicable governance rules or regulatory obligations may cause damages to our reputation or other material adverse effects to our results of operation or financial condition.

The rules for electricity trading and market conditions may affect the sale prices of electricity.

We perform trading activities through power purchase and sale agreements, mainly in the Free Market, through our generation and trading companies.

Energy trading is affected by changes in the methodology used to calculate energy price in the short-term (Preço de Liquidação de Diferenças, or PLD). PLD is currently determined by the results of optimization models of operation of the interconnected systems used by the ONS (Operador Nacional do Sistema Elétrico) and by CCEE (Câmara de Comercialização de Energia Elétrica). In such determination, there may be data entry errors or errors in the model, which may lead to an unexpected change of the PLD and possible future republications of the PLD. Thus, there is a risk for the commercial business with respect to the alteration of these models, data entry errors and republishing of the PLD, which may cause market uncertainty, reduction of liquidity, and financial losses with unexpected price variation. As of January 1, 2021, the PLD is officially calculated for each submarket on an hourly basis, as proposed by the Standing Committee for Analysis of Methodologies and Programs (Comissão Permanente para Análise de Metodologias e programas Computacionais do Setor Elétrico or CPAMP), in accordance with the implementation schedule defined by MME (Ministério de Minas e Energia) Ordinance No. 301/2019.

Additionally, any change in the energy trading rules related to the increase of restrictions for the entry of new consumers in the Free Market may affect our energy trading business.

Our business could be adversely affected by the performance of our suppliers, contractors or other third parties we do not control.

Suppliers, contractors and other third parties may fail to perform existing contracts and obligations, which may unfavorably impact our operations and financial results.

Further, being a mixed capital publicly-held company, we are legally obliged to engage a bidding process for the acquisition of equipment, materials and services, which may not guarantee the best quality of services, equipment and materials.

We are subject to climate factors and to uncertainties that may adversely impact our operation and results.

Our energy generation, transmission and distribution operations are subject to climatic factors and uncertainties related to severe weather events, mainly cyclones, hurricanes, floods, droughts and fires. These events can affect minimum water storage levels in hydroelectric plant reservoirs and lead to the unavailability of our electricity supply systems, impacting penalties by regulatory bodies, consumer complaints, lawsuits, costs for the restoration of systems, in addition to negatively affecting our results.

7

Further our wind farms’ operations are subject to climate factors and to uncertainties related to the speed of wind. The authorizations that govern our power generation activities in wind farms set forth certain performance covenants, which require us to generate minimum amounts of energy on annual and four-year bases in accordance with the energy amounts sold in the correspondent auctions. Non-compliance with such covenants may adversely impact our results.

We may acquire other companies in the electric sector or new energy concessions, as we already did in the past, which may increase our financial leverage and adversely affect our consolidated performance.

We constantly prospect for businesses that are related to our corporate purpose and aligned with our strategic plan. To expand our business, we may participate in auctions for the construction and operation of new power generation and transmission ventures, as well as invest in other companies from the energy sector, as we have done in the past. These acquisitions can increase our financial leverage or reduce our profits. In addition, the integration of the new businesses may not result in the synergy we expect in terms of efficiency gains and economies of scale for our operations, which may adversely affect our operational and financial performance.

Labor disputes may disrupt our operations from time to time.

Our employees are represented by unions. Disagreements regarding issues related to divestitures, changes to our business strategy, and reductions in the professional staff may lead to employee reactions. Strikes, work interruptions, or other forms of protests in any of our major suppliers or contractors or at their facilities may undermine our ability to complete relevant projects on time, negatively impacting our results of operations, and affect our ability to achieve long-term strategic goals.

Risks Relating to the Brazilian Electricity Sector and Other Sectors that We Operate

We are uncertain as to the renewal of certain of our generation and transmission concessions.

Under Federal Law No. 12,783/2013, or the 2013 Concession Renewal Law, we may only renew our concessions that were in effect as of 1995 (and, in the case of generation facilities, generation concession contracts entered into prior to 2003) for an additional 30-year period (or an additional 20-year period in the case of thermal plants), if we agree to amend the terms of the concession contract that is up for renewal to reflect certain new terms and conditions imposed by the 2013 Concession Renewal Law, which vary depending on whether the concession is for generation, transmission or distribution. If we do not agree to amend the concession contract to reflect these new conditions, the concession contract cannot be renewed and will be subject to a competitive bidding process upon its expiration, which we might not win. If we do not renew our generation and transmission concessions or if they are renewed under less favorable conditions, our financial condition and results of operations could be materially adversely affected. For more information, see “Item 4. Information on the Company—The Brazilian Electric Power Industry—Concessions”.

The concession agreement of our controlled company Compagas is under discussion with the granting authority

Compagas has entered into a concession agreement with the State of Paraná, as authority, pursuant to which the concession shall expire on July 6, 2024. The purpose of this concession is to provide piped gas distribution services and other related activities, to all segments of the consumer market, either as raw material or for the purpose of power generation or other uses made possible by technological advances.

The gas concession agreement is part of the so called “bifurcated model”, where part of the investments made by the concessionaire is paid by the users of the public service and the remaining part is indemnified by the granting authority, the State of Paraná, at the end of the concession.

On December 7, 2017, the State of Paraná enacted Complementary Law No. 205/2017, setting forth a new interpretation regarding the expiration date of the concession, leading to the understanding that the new expiration date was January 20, 2019. Notwithstanding the new expiration date provided by the state law, this concession has not been subject to neither an extension nor a new bidding process. Pursuant to applicable law, Compagas, as the current concessionaire, may continue to operate the concession until a new concessionaire is appointed.

8

Further, Complementary Law No. 227/2020, amended Complementary Law No. 205/2017 to revoke the provision on the expiration date of the concession as January 20, 2019.

Although the current Complementary Law 227/2020 ensures the concession expires on July 6, 2024, as originally foreseen in the concession agreement, and with which we agree, there is no guarantee that a future legislative change will change this scenario again, forcing us to to again discuss this issue in court.

In the event of non-extension of the concession, even if Compagas is entitled to compensation for the investments made in the last 10 years prior to the end of the concession, the financial condition and results of operations of our controlled company may be adversely affected. For more information see Note 2.1.1 to our audited consolidated financial statements.

Our operating results depend on prevailing hydrological conditions, which have been volatile recently. The impact of water shortages and resulting measures taken by the government to conserve energy may have a material adverse effect on our business, financial condition and results of operations.

We are dependent on the prevailing hydrological conditions throughout Brazil and in the geographic region in which we operate. According to data from ANEEL, approximately 64.0% of Brazil’s installed capacity currently comes from hydroelectric generation facilities. Hydrological conditions in our region, and Brazil in general, are frequently subject to changes because of non-cyclical deviations in average rainfall.

In previous periods of low rainfall, the Brazilian government reacted to poor hydrological conditions by seeking to reduce the consumption of electricity by Final Customers by several means, from general conservation campaigns to raise public awareness to rationing programs. The effect of conservation campaigns is not very predictable, making it difficult for our distribution business to accurately estimate the volume of energy it needs to purchase for sale to Final Customers. In case of mandatory rationing program, our distribution business would be adversely affected because its revenues are partially based on the volume of electricity it provides through our distribution grid to Final Customers.

With respect to our generation business, in order to compensate for poor hydrological conditions and to maintain adequate water levels in reservoirs, the ONS may order the reduction of generation from Hydroelectric Power Plants, which would be partially compensated by increased generation by Thermoelectric Plants. This mechanism for replacing hydroelectric production with thermoelectric production may not provide all of the energy we need to fulfill our obligations under existing energy supply contracts. To compensate for this deficit, our generation business can be required to purchase energy in the Spot Market, typically at higher prices, and we would not be able to pass on these increased costs. This mechanism impacts all generation companies in Brazil regardless of whether the geographical region in which a specific generator is located is experiencing low rainfall and could have a material adverse effect on our generation business. For more information, see Note 14.1 to our audited consolidated financial statements.

In addition, in an extreme scenario, given the increased presence of thermal generation in the national electric matrix, if a shortage of natural gas were to occur, this would increase the general demand for hydroelectric energy in the market and therefore increase the risk that a rationing program would be instated.

Regarding our energy trading business, the effect of volatility in hydrological conditions is the increase of the variation of energy price, which in turn increases the Spot Market volatility, thus affecting our operating results. Spot price (PLD) is determined by the results of optimization models of operation of the interconnected systems used by the ONS (Operador Nacional do Sistema Elétrico) and by CCEE. The energy average prices in the short term ("spot") are calculated by CCEE every hour and are set for each region.

When there is great availability of hydrological resources, the spot price tends to remain at lower levels, which may not be enough to (i) cover the generation costs of this very same energy (when related to our generation business) and (ii) cover the cost of the power purchase and sale agreement in our energy trading business.

Conversely, if hydrological availability is affected, spot prices tend to increase significantly, in addition to occasionally impacting the GSF, which may adversely impact our costs of energy purchases, as the price set forth in power purchase and sale agreements may not be sufficient.

ANEEL could penalize us for failing to comply with the terms of our concessions or with applicable laws and regulations, and we may not recover the full value of our investment in the event that any of our concessions are terminated.

Our concessions are for terms of 20 to 35 years and may be extended if certain conditions are met. In the event that we fail to comply with any term of our concessions or applicable law or regulation, ANEEL may impose penalties on us, which may include warnings, the imposition of potentially substantial fines and restrictions on our operations, among others. ANEEL may also terminate our concessions prior to the expiration of their terms if we fail to comply with their provisions or if they determine that terminating our concessions would be in the public interest, through a forfeiture or expropriation proceeding. In particular, our renewed distribution concession agreement contains both quality and financial metrics that become more restrictive over time, and that we must meet to ensure that our distribution concession agreement is not terminated. If ANEEL terminates any of our concessions before its expiration, we would not be able to operate the segment(s) of our business that had been authorized by the concession. Furthermore, any compensation that we may receive from the Brazilian government for the unamortized portion of our investment may not be sufficient for us to recover the full value of our investment. The early termination or non-renewal of any of our concessions or the imposition of severe fines or penalties by ANEEL could have a material adverse effect on our financial condition and results of operations. See “Item 4. Information on the Company—The Brazilian Electric Power Industry—Concessions”.

We are subject to comprehensive regulation of our business, which fundamentally affects our financial performance.

Our business is subject to extensive regulation by various Brazilian legal and regulatory authorities, particularly the MME and ANEEL, which regulate and oversee various aspects of our business and approve our tariffs. Changes to the laws and regulations governing our operations, which have occurred in the past, could adversely affect our financial condition and results of operations.

For example, the tariffs that we charge for sale of electricity to Captive Customers are determined pursuant to a concession agreement with the Brazilian government through ANEEL. The tariff rates we charge our customers are determined pursuant to a concession agreement and in accordance with ANEEL’s regulation. In addition, ANEEL’s decisions relating to our tariffs may be contested by public authorities or by our customers. Administrative and judicial decisions resulting from these challenges may modify ANEEL’s decisions in a manner that is unfavorable to us, which may adversely affect our financial condition and results of operations.

If any further regulations or new laws are passed by the Brazilian government to lower electricity prices, these new laws and regulations could have a material adverse effect on our results of operations.

Certain customers in our distribution concession area may cease to purchase energy from our distribution business.

Our distribution business generates a large portion of its revenues by selling energy that it purchases from generation companies. Large electricity customers within the geographic area of our concession that meet certain regulatory requirements may qualify as free customers (“Free Customers”). A Free Customer in our distribution concession area is entitled to purchase energy directly from generation and energy trading companies rather than through our distribution business, in which case that Free Customer would cease to pay our distribution business for that energy that we previously supplied.

In addition, ANEEL has issued regulations related to micro and mini distributed generation, which has been facilitating the purchase or lease of power generation equipment by customers, especially solar photovoltaic modules, to produce energy for their own consumption. Such regulation is currently under review and its outcome is difficult to predict. If the number of customers with micro and mini distributed generation within the geographic area of our concession increases, our revenues and results of operations could also be adversely affected.

We generate a portion of our operating revenues from Free Customers who may seek other energy suppliers upon the expiration of their contracts with us.

As of December 31, 2020, we had 912 Free Customers, representing approximately 8.0% of our consolidated operating revenues and approximately 14.9% of the total volume of electricity sold by us.

10

Regarding our energy trading company, as of December 31, 2020, our energy trading company had 877 Free Customers, representing approximately 4.8% of our consolidated operating revenues and approximately 8.6% of the total volume of electricity we sold in 2020.

Copel GeT has 35 Free Custumers on December 31, 2020. Approximately 55.2% of the megawatts-hours sold under contracts to such customers by Copel GeT expired in 2020. These customers represented approximately 6.3% of the total volume of electricity we sold in 2020, and approximately 3.2% of our consolidated operating revenues. Our contracts with Free Customers are typically for periods ranging between two years and five years in our generation business. There can be no assurance that Free Customers will enter into contracts or extend their current contracts to purchase energy from us.

Additionally, it is possible that our large industrial clients could be authorized by ANEEL to generate electric energy for their own consumption or sale to other parties, in which case they may obtain an authorization or concession for the generation of electric power in a given area, which could adversely affect our results of operations.

We may be forced to purchase or sell energy in the Spot Market at higher or lower prices and we may not be entitled to pass on any increased costs or incurred losses to our Final Customers in a timely manner, or at all.

Under the New Industry Model Law, electric energy distributors, including us, must contract, through public bids conducted by ANEEL, 100% of the forecasted electric energy demand for their respective distribution concession areas. The auctions in which the distributors are allowed to purchase energy are held up to seven years prior to the actual delivery of electric energy. We cannot guarantee that our forecasts for energy demand in our distribution concession area will be accurate. If our forecasts fall short of actual electricity demand, or if we are unable to purchase energy through the regulated market due to lack of energy supply in the market, or if a generation company fails to deliver energy that was previously contracted, we may be forced to make up for the shortfall by entering into short-term agreements to purchase electricity in the Spot Market where we may pay significantly more for energy without being able to pass on these increased costs to our Final Customers. In addition, if we underestimate our distribution energy needs, we may be subject to penalties imposed by the CCEE. Moreover, if our forecasts surpass actual demand by more than the allowed margin (105% of actual demand), including where demand is depressed due to government campaigns in response to poor hydrological conditions or due to reduced economic activity, we will not be able to pass on to our Final Customers the cost of the excess energy that we acquire.

We are subject to a counterparty’s credit risk in agreements entered into with Copel Comercialização (Copel Mercado Livre) and in case of default, we may have to sell or purchase energy at a different base price.

Copel Comercialização is subject to a counterparty’s credit risk. When Copel Comercialização sells energy, the counterparties to power purchase agreements may default on their contractual obligations, which may cause Copel Comercialização to sell energy at a different base price. In cases where Copel purchases energy, whether from energy generation projects, in operation or under construction, or even from energy trading, the selling counterparties may also default on the relevant contracts, and, consequently, Copel Comercialização may have to buy energy at a different base price and be subject to regulatory penalties imposed by CCEE due to insufficient contractual guarantees. Even though the Company performs credit analyses in accordance with market standards and requires its counterparties to provide guarantees in connection with the power purchase and sale agreements, we cannot guarantee that our counterparties will not fail to comply with their payment obligation or with their obligation to deliver energy to Copel, as the case may be, which may adversely affect our results.

We are subject to the risk of exchange rate variation if we start to perform energy import business, as well as if we perform business involving natural gas

Our subsidiary Copel Comercialização (Copel Mercado Livre) obtained authorization from the Ministry of Mines and Energy to import energy from neighboring countries, Argentina and Uruguay, and if we start doing business in this regard, we will be subject to the risk of exchange rate fluctuation. This subsidiary was also authorized by the National Agency of Petroleum, Natural Gas and Biofuels to operate in the sale of natural gas within Brazil. Although the natural gas business still has an incipient market in Brazil, if we do business in this area, we will be subject to the risk of exchange rate variation, considering that these transactions are carried out in foreign currencies.

11

We are subject to unrealized losses or net gains arising out from the mark-to-market of the purchase and sale of energy contracts, which may expose the Company to the risk of future energy prices

Our subsidiary Copel Comercialização (Copel Mercado Livre) negotiates energy purchase and sale transactions, and part of its agreements are classified as derivative financial instruments measured at fair value through its results. Unrealized net losses or gains resulting from the mark-to-market of these contracts (difference between contracted prices and market prices) are recognized in the results of the fiscal year. This activity may expose the Company to the risk of future energy prices.

Our equipment, facilities and operations are subject to numerous environmental and health regulations, which may become more stringent in the future and may result in increased liabilities and increased capital expenditures.

Our distribution, transmission and generation activities are subject to comprehensive federal, state and local legislation, as well as supervision by Brazilian governmental agencies that are responsible for the implementation of environmental and health laws and policies. These agencies could take enforcement action against us for our failure to comply with their regulations and with requirements established for the maintenance of our environmental licenses. These actions could result in, among other things, the imposition of fines, embargoes and revocation of licenses, which could have a material adverse effect on our financial condition and results of operations. It is also possible that enhanced environmental and health regulations will force us to allocate capital towards compliance, and consequently, divert funds away from planned investments. Such a diversion could have a material adverse effect on our financial condition and results of operations.

We are strictly liable for any damages resulting from inadequate provision of electricity services and our insurance policies may not fully cover such damages.

We are strictly liable under Brazilian law for damages resulting from the inadequate provision of electricity distribution services. In addition, our distribution, transmission and generation utilities may be held liable for damages caused to others as a result of interruptions or disturbances arising from the Brazilian generation, transmission or distribution systems, whenever these interruptions or disturbances are not attributed to an identifiable member of the National Electric System Operator, the Operador Nacional do Sistema Elétrico (“ONS”). We cannot assure you that our insurance policies will fully cover damages resulting from inadequate rendering of electricity services, which may have an adverse effect on us.

We are the controlling shareholders of a company that operates a gas distribution business (Compagas) and we are consequently exposed to risks inherent to this sector.

We control a business in the gas distribution sector, which is operated by Companhia Paranaense de Gas – Compagas. This company is entitled to exclusive rights with respect to the supply of piped gas in the State of Paraná. The clients of this business are Thermoelectric Plants, cogeneration plants, gas stations, other companies and residences.

Businesses in the gas distribution sector are subject to a broad set of risks inherent to its operation, including among the main ones:

• Regulatory instability,

• Shortage of natural gas,

• Depending on a single supplier in Brazil,

• Capacity of financing expansion,

• Operational failures and accidents in distribution,

• Performance of outsourced service providers,

• Alternative energy sources,

• Quality in service.

12

As a result of these uncertainties, there is no guarantee that the purposes of our gas distribution business will be achieved, which may have an adverse effect on our results of operations and our business.

We are still the controlling shareholders of a company that operates a telecommunications business (Copel Telecomunicações S.A.) and we are consequently exposed to the risks inherent to this sector.

We control a business in the telecommunications sector under an authorization granted by the National Telecommunications Agency (Agência Nacional de Telecomunicações – “ANATEL”). This business provides telecommunications services through the use of fiber optics. It also provides a number of telecommunications services to other companies of the Copel group.

On November 9, 2020, Copel Telecom's divestment auction was held at B3 S.A. – Brasil , Bolsa, Balcão. The winning bid was R$ 2.4 billion (equity value). On January 14, 2021, a Share Purchase Agreement for the sale of 100% of Copel Telecom was entered into with Bordeaux Multi-Strategic Investment Fund – Bordeaux Fundo de Investimentos em Participações Multiestratégia, the winning bidder of the auction. Certain conditions precedent, such as approval by ANATEL and the Administrative Council for Economic Defense (Conselho Administrativo de Defesa Econômica – “CADE”) have not yet been concluded. Thus, the process of divestment in the control of the subsidiary Copel Telecomunicações SA is still ongoing, and, if the conditions precedent are not completed, the transaction may not close. Failure to complete such sale may force us to keep the operations in the telecommunications sector longer than expected.

Businesses in the telecommunications sector are subject to a broad set of risks inherent to its operation, such as:

• Regulatory instability,

• Increase in competition,

• Technological changes,

• Capacity of financing our expansion,

• Failures in technological systems and information security,

• Performance of outsourced service providers,

• Exchange rate fluctuations,

• Variation in operating costs,

• Operational failures,

• Quality in service.

If it is not possible to implement our proposal to divest control of Copel Telecomunicações S.A., we will need to reevaluate our strategy in the telecommunications sector

Considering that the process of potential divestment in the control of the subsidiary Copel Telecomunicações SA is in progress, as approved by the Board of Directors, this process may not be materialized, judicial decisions or restrictions imposed by regulatory bodies or other governmental entities or other unknown factors. Failure to complete such sale may force us to reevaluate our divestment strategy in the telecommunications sector.

13

We cannot assure the speed of our innovation capacity and our responses in view of the changes the energy sector has been going through as a result of technology advances.

The electric energy sector has been going through changes driven by (i) the decentralization of the power generation systems; (ii) advances in energy storage technologies; (iii) dissemination of digital technologies that improve the efficiency of energy generation, transmission and consumption; (iv) increase of renewable energy sources, such as wind and solar energy; and (v) a tendency of reducing carbon footprints in the energy system, as part of the global efforts to mitigate the effects of climate change. These changes present many challenges and we may not be able to keep up with the effects of the increasing adoption of digital technologies in the electric energy sector and the significant potential of new technology solutions (both with respect to the improvement of processes and services provided to consumers and with respect to the development of new products that may lead to higher productivity gains, more affordable prices, higher competition and the creation of new markets). Investments in research and development may contribute to mitigate the risks related to the transformations of the energy sector and create new opportunities.

Risks Relating to Brazil

The Brazilian Government has significant influence over the Brazilian economy. Brazilian economic and political conditions— and investor perception of these conditions— have a direct impact on our operation.

Historically, the country’s political situation has influenced the performance of the Brazilian economy, and political crises have affected the confidence of investors and the general public, which resulted in economic deceleration, the downgrading of credit ratings of the Brazilian government and Brazilian issuers, and heightened volatility in the securities issued abroad by Brazilian companies.

Additionally, the Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy and often changes monetary, credit, exchange and other policies to influence Brazil’s economy. Our business, financial condition, results of operations and prospects may be adversely affected by changes in government policies, as well as other factors including, without limitation:

• exchange rate movements and volatility;

• inflation and changes in interest rates;

• exchange control policies;

• fiscal policy and changes in tax laws;

• other political, diplomatic, social and economic developments that may affect Brazil or the international markets;

• controls on capital flows; and/or

• limits on foreign trade.

In the last few years, Brazil faced adverse fiscal developments and political instability. Brazilian GDP decreased by 4.1% in 2020, grew by 1.1% in 2019 and grew by 1.3% in 2018. Unemployment rate was 13.5% in 2020, 11.9% in 2019 and 11.6% in 2018. Inflation, as reported by the consumer price index (IPCA), was 4.52% in 2020, 4.31% in 2019 and 3.75% in 2018. The Brazilian Central Bank’s base interest rate (SELIC) was 2.0% on December 31, 2020, 4.5% on December 31, 2019 and 6.5% on December 31, 2018. Future economic, social and political developments in Brazil may impair our business, financial condition or results of operations, or cause the market value of our securities to decline.

Changes in, or uncertainties regarding the implementation of, the policies above, might generate or contribute to uncertainties in the Brazilian economy. This would increase the volatility of the domestic capital market and the value of Brazilian securities traded abroad, and adversely affect our business, results of operations and financial condition.

14

Moreover, taking into account the Brazilian presidential system of government, and the considerable influence of the executive power, it is not possible to predict whether the present government or any successive governments will have an adverse effect on the Brazilian economy, and consequently on our business.

The effects of the COVID-19 pandemic of the coronavirus may have a material adverse impact on our operations and results

In December 2019, the outbreak of the Coronavirus Disease 2019 (COVID-19), spread throughout the world, being declared by the World Health Organization (WHO) as the COVID-19 outbreak pandemic, in March 2020. The impact on the global economy and financial markets has been significant and the overall consequences are still uncertain.

As a result, ANEEL, the Federal and the State Governments, particularly the State of Paraná, enacted a number of measures and regulations in response to the COVID-19 outbreak pandemic, aiming at protecting certain consumers, such as low income consumers and essential services and activities, while preserving public electricity distribution services during the COVID-19 outbreak pandemic.

With regards to the captive distribution market, Copel may experience in the short term (i) a significant reduction in revenue and collection from energy supply chains, (ii) defaults of large high voltage customers, and (iii) defaults of commercial class clients. In the medium term, Copel negative impacts may extend to other customer classes, especially residential ones.

A possible increase in payment defaults by residential consumers, coupled with the decrease in collection and the standstill of several commercial and industrial activities, resulting from social isolation measures, can adversely affect the financial and economic results involving the activities of the electricity sector, mainly the electricity distributors. Eventually, with the decrease in energy consumption, the Company may be in a position above the permitted regulatory limit for over contracting electricity.

Copel has followed the load projections issued by official bodies in the electricity sector strongly impacted by the drop in consumption in the commercial and industrial segments. This fall has caused notifications by energy buyers, under the perspective and allegation of unforeseeable circumstances and force majeure generated by the COVID-19 outbreak pandemic, requiring a reduction in the amounts of energy contracts and/or installments of defaulted bills.

Adverse impacts of the COVID-19 outbreak pandemic can also be felt on the implementation of generation and transmission projects, or on the availability of existing assets resulting from local actions, preventing access to facilities or problems with suppliers in the sector, also affected by the COVID-19 outbreak pandemic .

To the extent the government does not adopt a joint solution for the energy sector as a means to control or remove risk for the sector as a whole, the Company may suffer, among other impacts, cash damages, decreases in its profitability and the impossibility of performing certain operational activities.

We have established a Contingency Committee in light of the COVID-19 outbreak pandemic with the objective of monitoring and mitigating current and futures impacts and consequences in our activities. The Contingency Committee has four main focus objectives: (i) people’s safety, (ii) continuation of essential activities of the Company, (iii) monitoring guidelines and requirements of regulatory bodies, and (iv) preservation of adequate financial conditions to support the crisis. The Company has also continuously been (A) monitoring the impacts of the COVID-19 pandemic on (i) its contracts, (ii) suppliers and (ii) the liquidity of the energy market and its short-term pricing, as well as (B) involved and negotiating with the relevant authorities for the implementation of guidelines that guarantee the maintenance of the economic and financial sustainability of Brazil’s electricity power generation, transmission, commercialization and distribution chain.

15

Fluctuations in currency exchange rates and the devaluation of the real may adversely affect our net income and cash flow.

The Brazilian currency has been devalued periodically in the past in relation to the U.S. dollar and other foreign currencies. At the end of 2018, the exchange rate between the real and the U.S. Dollar was of R$3.87 per US$1.00. As of December 31, 2019, the exchange rate between the real and the U.S. Dollar was of R$4.03 per US$1.00, depreciating 4.0% against the U.S. Dollar. As of December 31, 2020, the real vs. U.S. dollar exchange rate recorded was R$5.19 to US$1.00, depreciating 28.8% against the U.S. Dollar, compared to the exchange rate recorded on December 31, 2019. Depreciation of the real increases the cost of servicing our foreign currency-denominated debt and the cost of purchasing electricity from the Itaipu – a hydroelectric facility, one of our major suppliers, which adjusts its electricity prices based in part on its U.S. dollar costs. Indeed, depreciation generally curtails access to international capital markets and may prompt government intervention. It also reduces the U.S. dollar value of our dividends and the U.S. dollar equivalent of the market price of our common shares and the ADSs.

Inflation and governmental measures to curb inflation may contribute to economic uncertainty in Brazil, and could reduce our margins and the market price of the Class B Shares and ADSs.

Brazil has in the past experienced extremely high rates of inflation. More recently, Brazil’s annual rates of inflation, measured in accordance with the variation of the Índice Geral de Preços - Disponibilidade Interna (“IGP-DI”) index, were 8.26% for the three-month period ended March 31, 2021, 23.7% in the year 2020, 7.7% in the year 2019, 7.1% in the year 2018 and (0.4)% in 2017. The Brazilian government has in the past taken measures to combat inflation, such as raising the basic Selic interest rate to elevated levels, and public speculation about possible future government actions has had significant negative effects on the Brazilian economy. Although our concession contracts provide for annual adjustments based on inflation indexes, if Brazil experiences substantial inflation in the future, and the Brazilian government adopts inflation control policies similar to those adopted in the past, our costs may increase faster than our revenues, our operating and net margins may decrease and, if investor confidence lags, the price of the Class B Shares and ADSs may fall. Inflationary pressures may also curtail our ability to access foreign financial markets and could lead to further government intervention in the economy, including the introduction of government policies that may adversely affect the overall performance of the Brazilian economy.

Allegations of political corruption against the Brazilian government and the Brazilian legislative branch could create economic and political instability.

Currently, several former and current members of the Brazilian executive and legislative branches of government are being investigated as a result of allegations of unethical and illegal conduct identified by the Operation Car Wash (Operação Lava-Jato) being conducted by the Office of the Brazilian Federal Prosecutor, and a number of politicians and businessmen have been arrested. The potential outcome of these investigations is unknown, but they have already had an adverse impact on the image and reputation of the investigated companies, in addition to adversely impacting general market perception of the Brazilian economy, including our business, financial condition and results of operations, as well as the trading price of our common shares and ADSs. Moreover, the conclusion of these proceedings or further allegations of illicit conduct could have additional adverse effects on the Brazilian economy. We cannot predict whether such allegations will lead to further instability or whether new allegations against key Brazilian government officials will arise in the future. In addition, we cannot predict the outcome of any such allegations and their effect on the Brazilian economy.

Changes in Brazilian tax policies may have an adverse effect on us and our shareholders.

The Brazilian government has in the past changed its tax policies in ways that affect the electricity sector, and it may do so again in the future. These changes include increases in the tax rates affecting energy companies and, occasionally, the collection of temporary taxes related to specific governmental purposes. If we are unable to adjust our tariffs accordingly, we may be adversely affected.

Considering the Brazilian Government's intention to replace Contributions to PIS / PASEP and Cofins with Contribution on Goods and Services (Contribuição sobre Bens e Serviços) – CBS (Bill No. 3887/2020), we formalized a group of work to assess the impacts and risks that this change may have on our results. Taking into account the market in which we operate, with regulated tariffs and bilateral contracts, which are expected to rebalance prices in the event of new taxes, our working group concluded that the impacts for us will likely be low. However, for the final consumers of our distribution concession area, we estimate that the impacts will be medium, in view of the possible tariff increase due to the increase in the rate of the new tax.

16

There are also bills under discussion at the National Congress of Brazil that may change the way in which taxes are collected in Brazil, including the collection of income tax on dividends, which may adversely affect our shareholders.

Negative developments in other national economies, especially those in developing countries, may negatively impact foreign investment in Brazil and the country’s economic growth.

International investors generally consider Brazil to be an emerging market. Historically, adverse developments in the economies of emerging markets have resulted in investors’ perception of greater risk from investments in such markets. Such perceptions regarding emerging market countries have significantly affected the market value of securities of Brazilian issuers. Furthermore, although economic conditions are different in each country, investors’ reactions to developments in one country can impact the prices of securities in other countries, including those in Brazil, and this may diminish investors’ interest in securities of Brazilian issuers, including ours.

Risks Relating to the Class B Shares and ADSs

ADSs holders may not have all the rights of our shareholders, and may be unable to exercise voting rights or preemptive rights relating to the shares underlying their ADSs.

Holders of the Class B Shares, and thus of the ADSs may not have the same rights that are attributed to our shareholders by Brazilian law or our bylaws, and the rights of ADS holders may be subject to certain limitations provided in the deposit agreement or by the securities intermediaries through which ADS holders hold their securities.

| – | Although ADS holders are permitted to vote at shareholders’ meetings, there are procedural steps involved in the process that create practical limitations on the ability of ADS holders to vote. In accordance with the Deposit Agreement, we will provide the notice to the Depositary, which will in turn, as soon as practicable thereafter, mail to holders of ADSs the notice of such meeting and a statement as to the manner in which instructions may be given by holders. To exercise their voting rights, ADS holders must then instruct the Depositary how to vote their shares. Because of this extra procedural step involving the Depositary, the process for exercising voting rights will take longer for ADS holders than for direct holders of Class B Shares. ADSs for which the Depositary does not receive timely voting instructions will not be voted.

| – | The holders of the Class B Shares may have fewer and less well-defined rights to protect your interests in connection with actions taken by our Board of Directors or the holders of Common Shares than under the laws of the United States and certain other jurisdictions outside Brazil. Although Brazilian law imposes restrictions on insider trading and price manipulation, the Brazilian securities markets are not as highly supervised as the United States securities markets or markets in certain other jurisdictions outside Brazil.

| – | The ability of ADS holders to exercise preemptive rights is not assured, particularly if the applicable law in the holder’s jurisdiction (for example, the Securities Act in the United States) requires that either a registration statement be effective or an exemption from registration be available with respect to those rights, as is in the case in the United States. We are not obligated to extend the offer of preemptive rights to holders of ADSs, to file a registration statement in the United States, and we cannot assure you that we will file any such registration statement. Accordingly, you may receive only the net proceeds from the sale of your preemptive rights by the Depositary or, if the preemptive rights cannot be sold, they will be allowed to lapse. If you are unable to participate in rights offerings, your holdings may also be diluted.

| – | ADS holders may not receive dividend payments if we incur net losses or our net profit does not reach certain levels. Under Brazilian Corporate Law and our by-laws, we must pay our shareholders a mandatory distribution equal to at least 25% of our adjusted net profit for the preceding fiscal year, with holders of preferred shares having priority of payment. According to our bylaws, Class A Shares and Class B Shares are entitled to receive annual, non-cumulative minimum dividends, which dividend per share shall be at least 10% higher than the dividends per share paid to the holders of the Common Shares. Class A Shares have a dividend priority over the Class B Shares to receive a minimum dividend equal to 10% of the total share capital represented by the Class A Shares outstanding at the end of the fiscal year in respect of which the dividends have been declared, and Class B Shares have a dividend priority over the Common Shares. In the event that we are unable to declare dividends, our management may nevertheless decide to defer payment of dividends or, in limited circumstances, not to declare dividends at all. We cannot make dividend payments from our legal reserve and capital reserve accounts.

17

Sales of a substantial number of shares, or the perception that such sales might take place, could adversely affect the prevailing market price of our shares or ADSs.

As a consequence of the issuance of new shares, sales of shares by existing share investors, or the perception that such a sale might occur, the market price of our shares and, by extension, of the ADSs may decrease significantly.

Future equity issuances may dilute the holdings of current holders of our shares or ADSs and could materially affect the market price for those securities.

We may in the future decide to offer additional equity to raise capital or for other purposes. Any such future equity offering could reduce the proportionate ownership and interests of holders of our shares and ADSs, as well as our earnings and net equity value per share or ADS. Any offering of shares and ADSs by us or our main shareholders, or a perception that any such offering is imminent, could have an adverse effect on the market price of these securities.

Holders of our ADSs may be unable to enforce judgments against our directors or officers.

All of our directors and officers named in this annual report reside in Brazil. Substantially all of our assets, as well as the assets of these persons, are located in Brazil. As a result, it may not be possible for holders of our ADSs to effect service of process upon us or our directors and officers within the United States or other jurisdictions outside Brazil, attach their assets or enforce against us or our directors and officers judgments obtained in the United States or other jurisdictions outside of Brazil. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain requirements are met, holders of ADSs may face greater difficulties in protecting their interest in actions against us or our directors and officers than would shareholders of a corporation incorporated in a state or other jurisdiction of the United States.

Judgments of Brazilian courts with respect to our shares will be payable only in reais.

If proceedings are brought in the courts of Brazil seeking to enforce our obligations in respect of our shares, we will not be required to discharge any such obligations in a currency other than reais (R$). Under Brazilian exchange control limitations, an obligation in Brazil to pay amounts denominated in a currency other than reais (R$) may only be satisfied in Brazilian currency at the exchange rate, as determined by the Brazilian Central Bank, in effect on the date the judgment is obtained, and any such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then prevailing exchange rate may not afford non Brazilian investors with full compensation for any claim arising out of, or related to, our obligations under our shares.

If you exchange your ADSs for Class B Shares, you risk increased taxes and the inability to remit foreign currency abroad.

Brazilian law requires that parties obtain a registration before the Brazilian Central Bank in order to be allowed to remit foreign currencies, including U.S. dollars, abroad. For the ADSs, the Brazilian custodian for the Class B Shares has obtained the necessary certificate from the Brazilian Central Bank for the payment of dividends or other cash distributions relating to the preferred shares or upon the disposition of the preferred shares. If you exchange your ADSs for the underlying Class B Shares, however, you must obtain your own certificate of registration or register in accordance with Brazilian Central Bank and CVM rules in order to obtain and remit U.S. dollars abroad upon the disposition of the Class B Shares or distributions relating to the preferred shares. If you do not obtain a certificate of registration, you may not be able to remit U.S. dollars or other currencies abroad and may be subject to less favorable tax treatment on gains with respect to the preferred shares. Pursuant to Brazilian Central Bank rules, obtaining this registration requires exchange transactions, which are subject to taxes in Brazil. For more information, see “Item 10. Additional Information—Taxation—Brazilian Tax Considerations—Other Brazilian Taxes”. If you attempt to obtain your own registration, you may incur expenses or suffer delays in the application process, which could delay your ability to receive dividends or distributions relating to the preferred shares or the return of your capital in a timely manner. The custodian’s registration before the Brazilian Central Bank and any certificate of foreign capital registration you obtain may be affected by future legislative changes. Additional restrictions may be imposed in the future on the disposition of the underlying Class B Shares or the repatriation of the proceeds from disposition.

The Brazilian government may impose exchange controls and restrictions on remittances abroad which may adversely affect your ability to convert funds in reais into other currencies and to remit other currencies abroad.

In the past, the Brazilian government has imposed restrictions on the remittance to foreign investors of the proceeds of their investments in Brazil and the conversion of Brazilian currency into foreign currencies. The Brazilian government could again choose to impose this type of restriction if, among other things, there is deterioration in Brazilian foreign currency reserves or a shift in Brazil’s exchange rate policy. Reintroduction of these restrictions would hinder or prevent your ability to convert dividends, distributions or the proceeds from any sale of Class B Shares, as the case may be, from reais into U.S. dollars or other currencies and to remit those funds abroad. We cannot assure you that the Brazilian government will not take similar measures in the future.

The relative volatility and illiquidity of the Brazilian securities markets may impair your ability to sell the Class B Shares underlying the ADSs.

The Brazilian securities markets are substantially smaller, less liquid, more concentrated and more volatile than major securities markets in the United States and certain other jurisdictions outside Brazil, and are not as highly regulated or supervised as some of these other markets. The illiquidity and relatively small market capitalization of the Brazilian equity markets may cause the market price of securities of Brazilian companies, including our ADSs and Class B Shares, to fluctuate in both the domestic and international markets, and may substantially limit your ability to sell the Class B Shares underlying your ADSs at a price and time at which you wish to do so.

Changes in Brazilian tax laws may have an adverse impact on the taxes applicable to a disposition of our shares or ADS.

Law No. 10,833 of December 29, 2003, provides that the disposition of assets located in Brazil by a non-resident to either a Brazilian resident or a non-resident is subject to taxation in Brazil, regardless of whether the disposition occurs outside or within Brazil. This provision results in the imposition of income tax on the gains arising from a disposition of our common or preferred shares by a nonresident of Brazil to another non-resident of Brazil. There is no judicial guidance as to the application of Law No. 10,833 and, accordingly, we are unable to predict whether Brazilian courts may decide that it applies to dispositions of our ADS between nonresidents of Brazil. However, in the event that the disposition of assets is interpreted to include a disposition of our ADS, this tax law would accordingly result in the imposition of withholding taxes on the disposition of our ADS by a non-resident of Brazil to another non-resident of Brazil.

There is no guarantee that the Conversion Offers will be successful.

As described in “Item 4. Information on the Company – Recent Developments”, on March 22, 2021, Copel offered to the holders of Class B Shares, including Class B Shares represented by ADSs, the ability to convert five Class B Shares into one unit, consisting of four Class B Shares and one common share of Copel. The conversion of shares and formation of Units will only occur if there is a minimum adhesion of approximately 60% (sixty percent) of the shares issued and outstanding. We cannot assure you that the Coversion Offers (as defined below) will be successful or, if successful, how the conversion will impact the pricing and liquidity of our shares.

Our revenues for each of the last three (3) financial years by activity are described in “Item 5. Operating and Financial Review and Prospects —Results of operations for the years ended December 31, 2020, 2019 and 2018”.

Historical Background

We were formed in 1954 by the State of Paraná to engage in the generation, transmission and distribution of electricity, as part of a plan to bring the electric energy sector under state control. We acquired the principal private power companies located in the State of Paraná in the early 1970s. From 1970 to 1977, we significantly expanded our transmission and distribution grid and worked to increase the connectivity of our network to networks in other Brazilian states. In 1979, a change in state law permitted us to extend our generating activities to include production from sources other than hydroelectric and thermal power plants.

Currently, we are the largest energy company in the State of Paraná. We are a corporation incorporated and existing under the laws of Brazil, with the legal name Companhia Paranaense de Energia – Copel. Our head offices are located at Rua Coronel Dulcídio, 800, CEP 80420-170 Curitiba, Paraná, Brazil. Our telephone number at the head office is +55 (41) 3331-4011. Our website is www.copel.com and any filings we make electronically with the SEC will be available to the public over the Internet at the SEC’s website. The commercial name of each of our businesses is provided as follows.

Relationship with the State of Paraná

The State of Paraná owns 58.6% of our Common Shares and, consequently, has the ability to control the election of the majority of the members of our Board of Directors, members of our Supervisory Board, the appointment of senior management and our direction, future operations and business strategy.

Corporate Structure

Prior to 2001, we operated as a single corporation engaged in the generation, transmission and distribution of electricity and in certain related activities. In compliance with the new regulatory regime, we transferred our operations to four wholly-owned subsidiaries (one each for generation, transmission, distribution and telecommunications) and our investments in other companies to a fifth wholly-owned subsidiary. This corporate restructuring was completed in July 2001.

In 2007, to comply with energy sector legislation, we divided the assets of our transmission business (“Copel Transmissão S.A.”) between our distribution business (“Copel Distribuição S.A.”) and our generation business, (“Copel Geração S.A.”). As a result, we changed the name of the latter entity to Copel Geração e Transmissão S.A.

In 2013, the Company was restructured in order to enhance the efficiency of our corporate structure and reduce our operating costs.

On January 28, 2016, our board of directors approved the amendment of the bylaws of Copel Participações S.A., in order to change its corporate purpose and denomination to Copel Comercialização S.A. The corporate purpose of this company is the sale of energy and rendering of related services. The restructuring that created Copel Comercialização S.A. (Copel Mercado Livre) is aimed at strengthening Copel’s positioning in the energy trading market and to improve its efficiency, allowing for greater agility and flexibility in the sale of energy.

In September 2017, in order to optimize the management of operating activities, the Company carried out an organizational restructuring of its wholly-owned subsidiary Copel Renováveis S.A., whose activities were absorbed by Copel Geração e Transmissão S.A,

On August 30, 2018, Copel GeT signed a Share Exchange Agreement with Eletrosul with respect to the joint ventures Costa Oeste Transmissora de Energia S.A. (51% - Copel GeT and 49% - Eletrosul), Marumbi Transmissora de Energia S.A. (80% - Copel GeT and 20%- Eletrosul) and Transmissora Sul Brasileira de Energia S.A. (20% - Copel GeT and 80% - Eletrosul). Under this agreement, Copel GeT started holding share of interest of 100% in the joint ventures Costa Oeste and Marumbi, in addition Eletrosul started to hold share of interest of 100% in Transmissora Sul Brasileira. The business combinations occurred on August 31, 2018, date of transfer of the shares.

21

In March 2019, Copel GeT signed a purchase and sale agreement with Centrais Elétricas Brasileiras S.A. and Fundação Eletrosul de Previdência e Assistencial Social - Elos to transfer 100% of the shares issued by SPE Uirapuru Transmissora de Energia SA. In June 2019, Copel GeT took over control of the company.

On October 18, 2019, Copel GeT, through a consortium with its subsidiary Cutia Empreendimentos Eólicos, participated in the A-6 new energy generation auction, having sold 14.4 average MW of the Jandaíra Wind Complex. The Jandaíra Wind Complex, which has 90.1 MW of installed capacity and 47.6 average MW of assured power, will be built in the northeastern state of Rio Grande do Norte, a region where Copel has other wind generation assets.

In order to renew the concession of HPP Gov. Bento Munhoz (or HPP Foz do Areia) for another 30 years, Copel incorporated the special purpose company F.D.A. Geração de Energia Elétrica S.A. (“FDA”) and, on March 03, 2020, requested the Ministry of Mines and Energy to apply Federal Decree no. 9,271/2018 (as amended by Federal Decree no. 10,135/2019), which conditions the renewal to the sale of the concession's corporate control in up to 18 months before the end of the current concession. On the same date, FDA signed with ANEEL the Brazilian Electricity Regulatory Agency, the Concession Contract that transfers the concession of the HPP Foz do Areia from Copel GeT to FDA, for the exploration of the plant until the end of the current concession, on September 17, 2023.

On November 9, 2020, Copel Telecom's divestment auction was held at B3 S.A. - Brasil, Bolsa, Balcão. The winning bid was R$ 2.4 billion (equity value). On January 14, 2021, a Share Purchase Agreement for 100% of Copel Telecom was entered into with Bordeaux Multi-Strategic Investment Fund – Bordeaux Fundo de Investimentos em Participações Multiestratégia, the winning bidder of the auction. We estimate that the transaction will close between the second or third quarter of 2021.

Copel currently has five wholly-owned subsidiaries, which are Copel Geração e Transmissão S.A., Copel Distribuição S.A., Copel Telecom, Copel Comercialização S.A. (Copel Mercado Livre) and Copel Serviços S.A.

Copel also holds 100% shareholding stake in several Special Purpose Companies (SPC).

The current organization of the group is as described as follows. All of our subsidiaries are incorporated in the Federative Republic of Brazil and subject to the Brazilian law.

BUSINESS

In the past, our generation and distribution businesses were integrated, and we sold most of the electricity we generated to the customers of our distribution business. This changed as a result of the implementation of the New Industry Model Law, enacted in 2004. Today, open auctions on the regulated market are still one of the primary channels by which our distribution business purchases energy to resell to Captive Customers and one of the channels by which our generation business generates revenues. Our generation business only sells energy to our distribution business through auctions in the regulated market. Moreover, our distribution business, like other certain Brazilian distribution companies, is also required to purchase energy from Itaipu, in an amount determined by the Brazilian government based on our proportionate share in the Brazilian electricity market. For more information, see “Item 4. Information on the Company—The Brazilian Electric Power Industry”.

The following table shows the total electricity we (i) generated through entities in which we hold a 100.0% shareholding stake and the 51.0% and 30.0% of energy generated by Mauá and Baixo Iguaçu Hydroelectric Plants respectively (corresponding to the interest we hold in each of these assets) and (ii) purchased in the last five years, broken down by the total amount of electricity generated and purchased by Copel Geração e Transmissão and our wind farm generation facilities described below (“Wind Farms”) and the total amount of electricity purchased by Copel Distribuição and Copel Comercialização (Copel Mercado Livre).

Generation

As of December 31, 2020, considering only the entities in which we hold a 100.0% shareholding stake and 51.0% and 30.0% of the energy generated by Mauá and Baixo Iguaçu Hydroelectric Plants, respectively (corresponding to the interest we hold in each of these assets), we operated and sold energy through nineteen (19) hydroelectric plants, twenty five (25) wind plants and one (1) Thermoelectric Plant, with a total installed capacity of 5,742 MW. Our assured energy totaled an average of 2,571 MW in 2020. Our generation varies yearly as a result of hydrological conditions and other factors. We generated 12,665GWh in 2020, 19,812 GWh in 2019, 19,935 GWh in 2018, 21,469 GWh in 2017 and 27,944 GWh in 2016.

Considering the installed capacity of all of the generation companies in which we have an interest (equity or otherwise), our total installed capacity as of December 31, 2020, was 6,399.6 MW.

The generation of electrical energy at our power plants is supervised, coordinated and operated by our Generation and Transmission Operation Center in the city of Curitiba. This operation center is responsible for coordinating the operations related to major part of our total installed capacity, including some of the plants in which we hold only partial ownership interests.

Governador Bento Munhoz da Rocha Netto (“Foz do Areia” Plant). The Foz do Areia Hydroelectric Power Plant is located on the Iguaçu River, approximately 350 kilometers southwest of the city of Curitiba.

Copel Geração e Transmissão SA (“Copel GeT”) held the concession for the exploration rights of the Governador Bento Munhoz da Rocha Netto Hydroelectric Power Plant (“UHE GBM”), in accordance with the Concession Agreement No. 045/1999, with the term of such concession until September, 2023. On the occasion of the termination of such concession, it is the Brazilian government’s responsibility to launch a new competitive bidding process for UHE GBM 's exploration rights, with wide competition between agents in the sector. Decree 9.271/18 allows the Brazilian government to grant a new concession contract for a period of up to 30 years to the winning legal entity of the privatization bidding of a public electricity generation service concessionaire under the control of the States.

26

The Company carried out studies to analyze the feasibility of becoming the winner in the future bidding process, and in the administrators’ assessment, the appetite of foreign investors represents a high risk for Copel, which may not be sufficiently competitive in the event of more efficient agents, or with lower financial cost for investments.

In this context, Copel GeT incorporated FDA and requested ANEEL for the transfer of the public electricity generation service for the plant in question. The transfer of the concession rights of UHE GBM to FDA took place under the terms of ANEEL Authorization Resolution No. 8,578, of February 11, 2020 and the Concession Contract for Generation of Electricity destined to the Public Service between FDA No. 002/2020.

On March 3, 2020, for the purposes of the provisions of Article 1st §2nd, item II of Decree No. 9.271/2018 (as amended by Decree No. 10.135/2019), Companhia Paranaense de Energia - Copel and Copel Geração e Transmissão S.A. filed a petition with the Ministry of Mines and Energy, through which they expressed their intention to privatize, by means of the sale of FDA’s control, associated with obtaining a Concession Agreement for 30 (thirty) years, counted as from its signing date, for the Governador Bento Munhoz da Rocha Netto Hydroelectric Plant. The petition provided that the privatization bidding, by means of the sale of FDA’s control, will be effected only after the acknowledgement and evaluation of the conditions involved in obtaining the concession rights, especially those related to the payment of the concession rights, in addition to the respective procedures and governance therefore.

In relation to the new concession agreement, the Ministry of Mines and Energy is responsible for defining the physical guarantee of energy, which should be included in the concession contract, as per §2º of art. 2 of Decree No. 5.163/2004.

On February 4, 2021, the Ministry of Mines and Energy published Directive (Portaria) No. 516/2021, which sets the physical guarantee of UHE GBM at 596.0 MWm (assured energy at 5,220.96 GWh/yr). The value is conditioned to the execution of the new concession agreement to be entered into by the company resulting from the privatization process, according to Decree No. 9,271/2018. The original value defined by the Ministry of Mines and Energy was 593.8 MWm (assured energy of 5,201.69 GWh/yr), however the value was revised after the approval of new parameters resulting from the modernization process of Generating Units 1, 2, and 4, approved by ANEEL through Order No. 3,245/2020. After reviewing the calculation of the physical guarantee of UHE GBM, the defined value is 596.0 MWm (assured energy at 5,220.96 GWh/yr).

Thermoelectric Generation Facilities

The following table sets forth certain information about our Thermoelectric Plants in operation as of December 31, 2020:

Plant | Installed capacity | Assured energy | Placed in service | Our ownership | Concession/ authorization expires
| (MW) | (GWh/yr) |  | (%) |
TPP Araucária | 484.2 | 2,604.5(1) | September, 2002 | 81.2 (2) | December, 2029
TPP Figueira | 20.0 | 90.5 | April, 1963 | 100.0 | March, 2019(3)

___________________

(1) The annual assured energy of thermal plants such as Araucária varies depending on the price of natural gas, according to criteria established by the MME.

(2) Held 20,3% by Copel and 60,9% by Copel GeT.

(3) We are currently waiting for the granting authority to amend our concession agreement with respect to TPP Figueira, extending the concession of the Thermoelectric Plant for another 20 years, pursuant to the Concession Extension Law of 2013

Araucária. We have an 81.2 % interest in UEG Araucária Ltda., which owns the Araucária Thermoelectric Plant, a natural gas thermoelectric power plant, located in the state of Paraná. The Araucária Thermoelectric Plant has 484.2 MW of installed capacity, does not have Availability Agreements currently in force and operates under a business model in which revenue depends on the plant’s operation. When produced, energy will be sold in the Spot Market as directed by the ONS.

As of November 2019, the plant may also have the possibility of being activated in the form of an assignment of energy credits, in accordance with the agreement signed with Petróleo Brasileiro S.A. - Petrobrás and in accordance with Normative Resolution No. 614/2014 from ANEEL. Based on this agreement, in force until December 31, 2020, the plant may be dispatched outside of out-of-merit-order, and the UTE Araucária gas supplier will inform, weekly, if it will activate the plant. In this scenario, the order will not be at the price of the CVU approved by ANEEL, but at a price agreed between the parties, considering, among other factors, market opportunities and margins considered adequate for the plant's operation, thus enabling recovery fixed cost for the order period.

A gas supply agreement was signed between Petróleo Brasileiro S.A - Petrobras and UEG Araucária Ltda - UEGA. The agreement is valid from January 01th to December 31th, 2021 and it provides for the delivery of up to 2,150,000 cubic meters of natural gas per day, without take-or-pay clauses. As a result, TPP Araucária will remain available to the National Interconnected System - SIN and can therefore be dispatched at the discretion of ONS. However, UEG Araucária signed an amendment to the Transfer of Energy Credits agreement with Petróleo Brasileiro S.A. - Petrobras, in accordance with ANEEL's Normative Resolution No. 614/2014, for the same duration as the gas supply agreement. The amendment will allow the plant to be dispatched out-of-merit-order, and the gas supplier will inform TPP Araucária weekly whether it will activate the plant. In this context, dispatch will not be charged at the CVU approved by ANEEL but at the value agreed by the parties, taking into account, among other factors, market opportunities and margins considered adequate for the operation of the plant, thus enabling the recovery of the fixed cost related to the dispatch period. With an installed capacity of 484.2 MW, the combined cycle power plant is one of the most efficient in Brazil.

31

TPP Araucária was activated on March 8, 2020, according to the schedule for the operational week of ONS. The dispatch order is part of the exceptional measures adopted at the meeting of March 4, 2020 by the Electric Sector Monitoring Committee (“CMSE”) for the recovery of hydroelectric reservoirs in the southern region of the country. The plant's remuneration, therefore, will be based on the Variable Cost per Unit - CVU approved by ANEEL, in the amount of R$681.79/MWh.

Figueira. The Figueira plant is located in the city of Figueira, in the northeast of the state of Paraná (where the main coal basin of Paraná is located). This plant is currently in a modernization process, which consists of replacing the old equipment for new equipment. This process aims to make this plant more efficient, reduce emissions of gases and particles resulting from the burning of coal and comply with applicable environmental legislation.

After the modernization, the plant will have the installed capacity of 20.0 MW with only one Generating Unit and the physical guarantee of 17.7 MW, so that it is in compliance with Normative Resolution No. 801/2017, which defines a minimum efficiency of 25% for installations with installed capacity up to 50.0 MW.

Expansion and Maintenance of Generating Capacity

We expect to spend R$429.8 million in 2021 to expand and maintain our generation capacity, including participation in new businesses, of which R$270.2 million will be invested in Jandaíra wind farm, R$35.6 million will be invested in Figueira Thermal Power Plant and R$22.0 million will be invested in the Cutia wind farm. The remaining amount will be spent on equipment maintenance, the modernization of the HPP Foz do Areia, SHP Bela Vista, Brisa Potiguar and São Bento Wind Farm Complex and other projects.

Hydroelectric Power Plant Projects

We have interests in several hydroelectric generation projects. The following table sets forth information regarding our major hydroelectric generation projects under construction.

Wind Farm Projects

The following table sets forth information regarding our wind farm projects, all of which currently refer to the Jandaíra wind farm (Complexo Eólico Jandaíra). In October 2019, Copel GeT and its subsidiary Cutia wind farm (Cutia Empreendimentos Eólicos) joined the Auction ANEEL A-6 for new energy generation and sold an average of 14.4 MW from the Jandaíra wind farm for R$98.00 MW/h. We expect to invest R$411.6 million in this new wind farm, which has an installed capacity equivalent to 90.1 MW and a physical guarantee equivalent to 47.6 MW. The Jandaíra wind farm will be built in the state of Rio Grande do Norte, and, as other wind farm assets of Copel are located in the same region, we believe that this project may benefit from operational synergies related to our projects that are already operating.

The amount of energy sold in October 2019 corresponds to 30% of the project’s physical guarantee. Pursuant to the power purchase agreement executed in connection with the above, such amount of energy shall be supplied as from January 1, 2025, this agreement will be in force for 20 years and prices will be adjusted pursuant to the IPCA index. Any additional energy generated by the Jandaíra wind farm will be negotiated in the Free Market.

Copel is also a member of Consortium Geração Luz Paranaense – CGLP, which was granted with exploration rights related to the following projects: (i) SHP Foz do Curucaca, (ii) SHP Salto Alemã, (iii) SHP Alto Chopim and (iv) SHP Rancho Grande. After obtaining the applicable authorization from ANEEL and evaluating the hydraulic potential of each project, the consortium decided to carry out the studies only with respect to SHP Salto Alemã and SHP Foz do Curucaca and to return the exploration rights for SHP Alto Chopim and SHP Rancho Grande projects to ANEEL. The basic designs of SHP Salto Alemã and of SHP Foz do Curucaca had already been approved by ANEEL and the environmental studies related to this project were registered in the competent entity (IAT – Instituto Água e Terra do Paraná or “IAT”) for analysis.

33

Since 2018, COPEL has held the rights of the HPP Salto Grande, located in the Chopim River in the state of Paraná. The environmental studies related to this project were registered with IAT for analysis in February 2020 and the basic design was approved by ANEEL in November 2020.

Taking into account that four energy auctions are planned in 2021, we intend to bid for concessions to construct and operate new hydroelectric and solar photovoltaic plants or wind farms in power auctions in the regulated market for new generation projects. We are studying the feasibility of our participation in the hydroelectric, wind farms and solar photovoltaic projects planned to be listed in the auctions of 2021 or sell the energy in the unregulated electricity market (Free Market). We will also conduct studies of new hydroelectric power plants. For instance, we have partnered with BE - Empresa de Estudos Energéticos S.A., Minas PCH S.A. and SILEA Participações Ltda. to develop studies in the lower region of the Chopim River, which may lead to the development of another four (4) hydroelectric projects. We are also conducting studies related to future government auctions for wind farms, solar photovoltaic and hydropower plants, small hydroelectric plants and thermoelectric power plants in which we may eventually participate. Other renewable energy projects under study or development include the use of municipal solid waste in power generation, and thermosolar energy. For instance, since 2017, Copel has conducted solarimetric measurements in two solarimetric stations located in areas leased by Copel Brisa Potiguar. The development of solar energy projects in such areas is still under analysis and the corresponding studies are expected to be concluded as to be able to submit such projects to energy auctions in 2021.

We are also developing studies for the implementation / acquisition of projects related to Generation Distribution, Biomass (sugar cane and forest residues), Biogas and Natural Gas. In addition to energy generation projects, investment opportunities in new energy transmission assets whose concession will be auctioned by the Brazilian government or existing assets that have synergy with our current portfolio are also being studied.

Transmission and Distribution

General

Electricity is transferred from power plants to customers through transmission and distribution systems. Transmission is the bulk transfer of electricity from generating facilities to the distribution system by means of the Interconnected Transmission System, in tension greater than or equal to 230 kV. Distribution is the transfer of electricity to Final Customers, in tension lesser or equal to 138 kV.

The following table sets forth certain information concerning our transmission and distribution grids on the dates presented.

___________________

(1) As approved by ANEEL in 2008, these 69 kV transmission lines held by Copel Distribuição were transferred to Copel Geração e Transmissão, since they were part of our transmission business segment.

(2) Due to improvements to registration and control systems used by Copel Distribuição to classify and register its transmission lines, lines were classified pursuant to its insulation voltage, and not according to its structure and isolate components. Consequently, all lines previously registered by Copel Distribuição were reclassified and there are no lines classified as 230 kV anymore.

(3) This figure includes transformers with primary tensions of 69 kV and 138 kV which belong to Copel Distribuição but are implemented in 230 kV and 525 kV substations, which belong to Copel Geração e Transmissão.

(4) Percentage of losses on the energy injected in the distributor (technical and non-technical losses on injected energy). Does not consider losses in the basic network.

(5) We note that percentages measured until 2016 and reported in previous reports of the Company reflected the amounts of physical losses (Technical), commercial losses (Non-Technical) and losses on the basic network (allocation of agreements on the gravity center of the submarket) of Copel Distribuição, as well as the losses related to the allocation of agreements of Copel GeT. Those percentages were calculated taking into account the total of power purchased and sale agreements entered into by both Copel Distribuição and Copel GeT. For a better representation and comparison of the percentage of losses, we considered the percentage obtained by dividing the total amount of technical and non-technical losses by the energy injected into the network of Copel Distribuição. This percentage may be compared to other companies and has a more accurate physical meaning as it utilizes the database of measured data and not information taken from agreements of the period being analyzed.

Transmission

Our transmission system consists of all our assets of 230 kV and greater and a small portion of our 69 kV and 138 kV assets, which are used to transmit the electricity we generate and the energy we receive from other sources. In addition to using our transmission lines to provide energy to customers in the State of Paraná, we also transmit energy through the Interconnected Transmission System. Two companies owned by the Brazilian government, Companhia de Geração e Transmissão de Energia Elétrica do Sul do Brasil – CGT Eletrosul and Furnas, also maintain significant transmission systems in the State of Paraná. Furnas is responsible for the transmission of electricity from Itaipu, while CGT Eletrosul’s transmission system links the states in the south of Brazil. Copel, like all other companies that own transmission facilities, is required to allow third party access to its transmission facilities in exchange for compensation at a level set by ANEEL.

Currently, we carry out the operation and maintenance of 3,524 km of transmission lines, forty one (41) substations in the State of Paraná and two (2) substations in the State of São Paulo. In addition, we have partnerships with other companies to operate 4,028 km of transmission lines and seven (7) substations through special purpose companies (SPCs).

Expansion and Maintenance of Transmission Facilities

The construction of new transmission facilities of 230 kV and higher must be awarded in a bidding process or otherwise authorized by ANEEL. We are permitted by ANEEL to make minor improvements to some of the existing 230 kV and 500 kV facilities.

In November 2013, SPC Mata de Santa Genebra Transmissora, a strategic partnership between Copel (50.1%) and Furnas (49.9%), won the right to build and operate 847 km of transmission lines and three substations in the States of Paraná and São Paulo. The construction schedule of the Mata de Santa Genebra project was affected by successive vandalism events, which resulted in the collapse of towers and theft of aluminum cables in transmission lines already installed and commissioned, in different sections of the project. On November 11, 2020, the LT 440 kV Fernão Dias / Taubaté, the last asset of the SPC Mata de Santa Genebra project, began its commercial operation. With the completion of these steps, the SPC Mata de Santa Genebra became fully operational. The project an APR of R$ 248.7 million, of which R$ 124.6 million are related to COPEL's stake.

In November 2015, Copel GeT won ANEEL’s public auction No. 005/2015 for the construction and operation of 188 km of transmission lines in the States of Paraná and Santa Catarina, and three (3) substations in the State of Paraná, with a total capacity of 900 MVA. With an APR of R$119.1 million, the corresponding concession agreement was signed in April 2016, and, the remaining facility which was still under construction, the transmission line Curitiba Leste - Blumenau, become operational in April 1, 2021. This facility had an auction APR of R$ 24.9 million and in current values, it has an APR of R$ 38.6 million, approved for 2020-2021 tariff adjustment cycle.

Distribution

Our distribution system consists of a widespread network of overhead lines and substations with voltages up to 138 kV assets. Higher Voltage electricity is supplied to bigger industrial and commercial customers and lower voltage electricity is supplied to residential, small industrial, and commercial customers in addition to other customers. As of December 31, 2020, we provided electricity in a geographic area encompassing approximately 97% of the State of Paraná and served 4.8 million customers.

Our distribution grid includes 202,085 km of distribution lines, 446,549 distribution transformers and 230 distribution substations of 34.5 kV, 36substations of 69 kV and 112 substations of 138 kV. During 2020, 122,612 new captive customers were connected to our network, including customers connected through the rural and urban electrification programs. We are continuing to implement compact grid design distribution lines in urban areas with large concentration of trees in the vicinity of the distribution grid.

We have five (5) captive customers that are directly supplied with energy at a high voltage (69 kV and above) through connections to our distribution lines. The volume of energy commercialized for these customers was 25.272MWh in 2020.

We are also responsible for expanding the 138 kV and 69 kV distribution grid within our concession area to meet any future demand growth.

On October 16, 2019 Copel Distribuição launched a program to modernize its distribution grid called “Transformation Program” (Programa Transformação). The Transformation Program is comprised of three projects: “Total Reliability” (Confiabilidade Total), “Three-phase Paraná” (Paraná Trifásico) and “Smart Grid Copel”. The goal is to improve infrastructure, particularly in rural areas, in order to enhance quality of energy supply and reduce supply restoration period in case of power outages. With investments of up to R$2.9 billion until 2025, which shall compose the Regulatory Remuneration Base, the Transformation Program involves the construction of approximately twenty-five 25,000 kilometers of power grids, 15,000 new automated power connections and the setting up of smart grid technology in the State of Paraná. The Smart Grid Project deals with the implementation of a communication network for distribution automation equipment and for smart meters. In addition, computer systems for efficient management of this communication network are included in this project.

Performance of the Distribution System

Total losses are commonly divided into a technical and non-technical component. Technical losses are inherent to the transportation of electricity and consist mainly of power dissipation in the line network. Non-technical (or commercial) losses are caused by actions external to the power system (for instance, electricity theft). Since total losses are comprised of both technical and non-technical parcels, the latter is easily calculated as the difference between total losses and the estimated technical losses inherent to the system.

Total losses in our distribution system are segmented between (i) losses in the basic network (tension equal to or greater than 230kV), which are external to our distribution grid and have a technical cause, and (ii) losses in the distribution network (internal to our distribution grid), which are usually caused by both technical and non-technical reasons.

Losses in the basic network are calculated monthly by the CCEE as the difference between the total generation and the energy effectively delivered to the distribution networks. The total losses from our distribution grid are calculated as the difference between the energy allocated to the system and the energy supplied to the customers.

Our total energy distribution losses (including transmission system, technical and commercial losses) totaled 9.4% of the total energy amount available in 2020, being (i) 1.6% related to losses in the basic network, (ii) 6.0% of technical losses and (iii) 1.8% of non-technical losses.

37

ANEEL grants the transfer of all energy losses to the final consumers when the real losses are less than regulatory losses. The calculation is made within the regulatory period, that is different from a civil year, and thereby we will know the result just in the next tariff adjustment, in June 2021. But our simulation indicates that in the civil year, from January through December 2021, we will have all losses transferred to the final consumers.

Furthermore, ANEEL requires distributors to observe certain standards for “energy supply continuity”, namely (i) duration of outages per customer per year or DEC – Duração Equivalente de Interrupção por Unidade Consumidora and (ii) frequency of outages per customer per year or FEC – Frequência Equivalente de Interrupção por Unidade Consumidora. Information regarding the duration and frequency of outages for our customers is set forth in the following chart for the years indicated.

Quality of supply indicator | 2020 | 2019 | 2018 | 2017 | 2016
DEC – Duration of outages per customer per year (in hours) | 7h50min | 09h07min | 10h19min | 10h28min | 10h49min
FEC – Frequency of outages per customer per year (number of outages) | 5.61 | 6.02 | 6.22 | 6.83 | 7.23

We comply with the quality indicators defined by ANEEL for 2020, which penalizes power outages in excess of an average number of hours per customer, in each case calculated on an annual basis. These limits vary depending on the geographic region, and the average limit established by ANEEL for our distribution company was 9 hours and 47 minutes of outages per customer per year, and a total of 7.38 outages per customer per year. Failure to comply with these predetermined standards with a Final Customer results in a reduction of the amount we can charge such Final Customer in future periods.

In addition, quality target indicators are taken into consideration by ANEEL during distribution concession renewal proceedings, and also influence ANEEL’s calculation of our tariff adjustments. For more information, see “–Concessions–Distribution Concessions” and “–The Brazilian Electric Power Industry–Distribution Tariffs”.

Itaipu

We purchased 5,498 GWh of electricity from Itaipu in 2020, which constituted 9.8%% of our total available electricity in 2020 and 22.1% of Copel Distribuição’s total available electricity in 2020. Our purchases represented approximately 7.2% of Itaipu’s total production. Distribution companies operating under concessions in the midwest, south and southeast regions of Brazil are required by law to purchase Brazil’s portion of the energy generated by Itaipu in a proportion that correlates with the volume of electricity that they provide to customers. The rates at which these companies are required to purchase Itaipu’s energy are fixed to cover Itaipu’s operating expenses and payments of principal and interest on Itaipu’s U.S. dollar-denominated borrowings, as well as the cost of transmitting the power to their concession areas. These rates are denominated in U.S. dollars, and have been set for 2021 at US$ 28.07 per kW per month.

In 2020, we paid an Average Tariff of R$ 327.09/MWh for energy from Itaipu, compared to R$237.94/MWh in 2019. These figures do not include the transmission tariff that distribution companies must pay for the transmission of energy from Itaipu.

ANGRA

Because Eletronuclear renewed the generation concession of Angra under the 2013 Concession Renewal Law, the energy generated by Angra is no longer sold in auctions in the regulated market. Rather, under the 2013 Concession Renewal Law, this energy is sold to distributors in accordance with the quota system established by said law. For more information, see “Item 4. Information on the Company—The Brazilian Electric Power Industry”. As a result, Copel Distribuição was legally required to purchase 968 GWh from Angra in 2020, 979GWh from Angra in 2019 and 1,009 GWh in 2018.

Assured Power Quota Contract – CCGF

Under the 2013 Concession Renewal Law, certain generation concessionaires renewed their concession contracts, and therefore these concessionaires no longer sell the energy produced by these generation facilities at auctions in the regulated market. Rather, this energy is sold to distribution companies in accordance with the quota system established by the 2013 Concession Renewal Law. For more information, see “Item 4. Information on the Company—The Brazilian Electric Power Industry”. Copel Distribuição is obligated to purchase energy from these generation concessionaires that have renewed generation concessions under this quota system. Copel Distribução was legally required to purchase 6,136 GWh in CCGF contracts in 2020, 6,274 GWh in CCGF contracts in 2019 and 6,520 GWh in CCGF contracts in 2018.

Auctions in the Regulated Market

In 2020, we purchased 11,733 GWh of thermoelectric and hydroelectric energy through auctions in the regulated market. This energy represents 47.3% of the total electricity purchased by the Copel Distribuição. For more information on the regulated market and the Free Market, see “Item 4. Information on the Company—The Brazilian Electric Power Industry”.

Sales to Captive Customers

During 2020, we supplied approximately 97% of the energy distributed directly to Captive Customers in the State of Paraná. Our concession area includes nearly 4.8 million customers located in the State of Paraná and in one municipality in the State of Santa Catarina, located in the south of the State of Paraná. During 2020, the total power consumption of our Captive Customers was 19,180 GWh, a 3.1% decrease as compared to 19,784 GWh during 2019.

Sales to Free Customers

We operate in the ACL through our wholly owned subsidiaries Copel Geração e Transmissão and Copel Comercialização (Copel Mercado Livre). As of December 31, 2020, we had 912 Free Customers (of which 877 were customers of our energy trading company and 35 of Copel GeT), representing approximately 8.0% of our consolidated operating revenue and approximately 14.9% of the total quantity of electricity sold by us. During 2020, the total power consumption of our Free Customers was 7,988GWh, a 16.4% increase as compared to 6,860 GWh during 2019.

Industrial and commercial customers accounted for approximately 10.2% and 17.9%, respectively, of our total revenues from sales to Final Customers of Captive Market during 2020. In 2020, 32.5%of our total revenues from energy sales were from to residential customers.

Tariffs

Retail Tariffs. We classify our customers in two groups (“Group A Customers” and “Group B Customers”), based on the voltage level at which electricity is supplied to them and on whether they are considered as industrial, commercial, residential or rural customers. Each customer falls within a certain tariff level defined by law and based on the customer’s classification, although some flexibility is available according to the nature of each customer’s demand. Under Brazilian regulation, low voltage customers such as residential customers (other than Low-income Residential Customers, as defined as follows) pay the highest tariff rates, followed by 13.8 kV and 34.5 kV voltage customers (usually commercial customers), and 69 kV and 138 kV voltage customers (usually industrial customers).

Group A Customers receive electricity at 2.3 kV or higher and the tariffs applied to them are based on the actual voltage level at which energy is supplied and the time of day the energy is supplied. Tariffs are comprised of two components: a “capacity charge” and an “energy charge”. The capacity charge, expressed in reais per kW, is based on the higher of (i) contracted firm capacity and (ii) power capacity actually used. The energy charge, expressed in reais per MWh, is based on the amount of electricity actually consumed as evidenced by our metering.

Group B Customers receive electricity at less than 2.3 kV, and the tariffs applied to them are comprised solely of an energy charge and are based on the classification of the customer.

ANEEL restates our tariffs annually, usually in June. For more information about the distribution tariff adjustments that have been made by ANEEL in recent years, see “Item 5. Operating and Financial Review and Prospects—Overview—Rates and Prices”.

The following table sets forth the Average Tariffs for each category of Final Customer in effect in 2020, 2019 and 2018.

Tariffs | 2020 | 2019 | 2018
| (R$/MWh)
Industrial | 487.41 | 488.78 | 767.87
Residential | 498.82 | 504.36 | 505.08
Commercial | 574.57 | 574.41 | 527.31
Rural | 489.57 | 466.9 | 345.80
Other customers | 356.03 | 364.49 | 375.99
All Final Customers | 537.81 | 534.32 | 514.94

Low-income Residential Customers. Under Brazilian law, we are required to provide low level rates to certain low-income residential customers (“Low-income Residential Customers”). In December 2020, we served approximately 331,061 low-income residential customers. For servicing these customers, in 2020 we received an approximately R$101.8 million contribution from the Brazilian government, which was approved by ANEEL.

The following table sets forth the current minimum discount rates approved by ANEEL for each category of Low-income Residential Customer.

Consumption | Discount from base tariff
Up to 30 kWh per month | 65%
From 31 to 100 kWh per month | 40%
From 101 to 220 kWh per month | 10%

Special Customers. A customer of our distribution business that consumes at least 500 kW (a “Special Customer”) may choose its energy supplier if that supplier derives its energy from alternative sources, such as small hydroelectric plants, wind plants or biomass plants. A Special Customer that chooses to purchase energy from a supplier other than Copel Geração e Transmissão continues to use our distribution grid and pay our distribution tariff. However, as an incentive for Special Customers to purchase from alternative sources, we are required to reduce the tariff paid by Special Customers by 50%. This discount is subsidized by the Brazilian government, and therefore does not impact the revenues of our distribution business.

Transmission Tariffs. A transmission concessionaire is entitled to annual revenues based on the transmission network it owns and operates. These revenues are annually readjusted according to criteria stipulated in the concession contract. We are directly a party to twelve (12) transmission concession contracts, eleven (11) of which are in the operational stage and one (1) of which includes a transmission line that is still under construction. Not all of the transmission concession contracts employ the same revenue model. 1.5% of our transmission revenues are updated on an annual basis by the IGP-M and the other 98.5% are subject to the tariff review process.

The first periodic revision related to our Main Transmission Concession scheduled for 2005 was only carried out in 2007, at which point ANEEL reduced the tariffs by 15.08%. This adjustment was applied retroactively to July 2005, and was passed on to our Final Customers until June 2009. In addition, in July 2010 pursuant to a second periodic revision of our principal concession, ANEEL granted provisional approval of a reduction in our transmission tariff by 22.88%, applied to the revenues of new installations in the Interconnected Transmission System, and applied retroactively from July 1, 2009 onward. In June 2011, ANEEL reviewed the figures of the second periodic revision and reduced the annual revenues by 19.94%. The remainder of our annual revenues was subject to adjustment by IGP-M or IPCA, as applicable.

By late 2012, Copel decided to anticipate the extension of its main transmission concession agreement (corresponding to 78% of our transmission lines then in operation) that would expire in 2015, pursuant to the new rules of the 2013 Concession Renewal Law. In December 2012, Copel executed the Third Addendum to the Concession Agreement 060/2001, extending this transmission concession agreement until December 31, 2042. In order to adjust these assets’ annual permitted revenue to the new rules of 2013 Concession Renewal Law, ANEEL reduced the transmission tariffs we charged by 61.9%.

Of all our transmission concessions in operational stage, our main transmission concession (which involves our main transmission facilities) accounted for about 71% of our gross transmission revenues in 2019. In addition, we have ten (10) concession agreements for transmission lines and substations in operation and one (1) partially in operation, which correspond to an aggregate of 29% of our transmission revenues. The amount of revenues we are entitled to receive pursuant to one (1) of these contracts is updated on an annual basis by the IGP-M and is not subject to the tariff review process, but, pursuant to the terms set forth in this agreement, our revenues were reduced by 50% starting in June 2018. Other ten (10) agreements revenues are subject to the tariff review process and adjustments by the IPCA.

In relation to our main concession agreement, on April 22, 2016, Ordinance No. 120/2016 of the Ministry of Mines and Energy determined that the amounts ratified by ANEEL related to the non-depreciated transmission assets existing on May 31, 2000 (Existing Basic Network System “RBSE”) should be incorporated to the Regulatory Remuneration Base, and that their cost of capital should be added to APR. The Ordinance also determined that the cost of capital would be composed of compensation and depreciation installments, plus related taxes, and recognized as of the 2017 tariff revision process, with adjustments and revisions in accordance with contractual conditions.

Also pursuant to the above mentioned Ordinance, the cost of capital not incorporated between the concessions’ extensions and the 2017 tariff revision process should be restated at the real cost of own capital of the transmission segment defined by ANEEL (10.4%) and, after the tariff revision process, it should be remunerated at the Weighted Average Cost of Capital (WACC) of 6.6%, also defined by that agency.

On May 9, 2017, ANEEL approved the result of the inspection of the appraisal report of the transmission assets existing on May 31, 2000 (RBSE and Other Transmission Facilities - RPC) related to our main transmission concession agreement. The Agency recognized the amount of R$667.6 million as the net value of the assets for the purposes of indemnification as of December 31, 2012. As of December 31, 2017, the net value of those assets for the purposes of indemnification amounted to R$1,418.4 million.

42

On June 27, 2017, ANEEL approved the Annual Permitted Revenue (Receita Anual Permitida, or APR) of the transmission assets of Copel GeT for the 2017/2018 cycle, including the commencement of receipt of the RBSE indemnification of our main transmission concession agreement.

In 2017(i) our main transmission concession agreement was adjusted by the IPCA and by the portion related the commencement of receipt of the RBSE indemnification (average increase of 151.3%) (ii) one of our transmission concession agreements was adjusted by the IPCA and improvements to the system were approved by ANEEL (average increase of 3.7%), (iii) six transmission concession agreements were adjusted by the IPCA (3.6%), (iv) one transmission concession agreement was adjusted by the IGP-M (1.6%), and (v) one transmission agreement became operational in August 2017, adding R$18.9 million of annual permitted revenues. As a result, the annual permitted revenues for the 2017/2018 cycle for our transmission assets reflected an increase of 121.2% over our annual permitted revenues for the 2016/2017 cycle.

In June 2018, ANEEL approved the APR for the 2018/2019 cycle, considering (i) an adjustment of relevant amounts by the IGP-M and IPCA indexes, and (ii) the expansion of our transmission system with strengthening works and revenues from other works classified as improvement measures.

Compared to our total APR for the 2017/2018 cycle, the APR of our main concession for the 2018/2019 cycle was reduced by 8.1%, as a result of the correction of a prior calculation made by ANEEL, which take into account certain financial and economic portions of unamortized and unrepaired assets related to the RBSE when determining the assets of the Regulatory Remuneration Base in the prior cycle.

The APR of concession No. 075/2001 was reduced by approximately 30.5%, as a result of a 50% reduction of the APR starting at the 16th anniversary of commercial operation, which occurred during the 2018/2019 cycle. Two of our concession agreements (022/2012 and 002/2013) were subject to a periodic review, which resulted in a lower APR in connection with increasing revenues related to strengthening works.

In June 2019, ANEEL approved the APR for the 2019/2020 cycle, considering (i) an adjustment of relevant amounts by the IGP-M and IPCA indexes, and (ii) the expansion of our transmission system with strengthening works and revenues from other works classified as improvement measures.

In 2020, in the scope of the tariff review process for the contracts extended under Law No. 12,783/2013, holders of assets belonging to RBSE had their review ratified in June 2020 despite originally being scheduled for 2018, due to a two-year delay and the retroactive effects of REN 880/2020 on the 2018 tariff year. For Copel, this process was ratified through Homologation Resolution No. 2,715/2020 for concession agreement No. 060/2001, granted to Copel GeT. During review process, by ANEEL’s deliberation it was decided that as of the 2020/2021 cycle, the renumeration portion of the RBSE would be calculated by the cost of equity (“KE”) as provided for in Ordinance MME No. 120/2016. The value not received during the three previous cycles (2017-2020) will be incorporated into the next three cycles (2020-2023) by the means of an Adjustment Installment (Parcela de Ajuste).

Additionally, by means of Homologation Resolution No. 2,725/2020, ANEEL established the readjustment of RAPs for electric energy transmission assets for the 2020-2021 cycle, effective from July 1, 2020 until June 30, 2021. According to the aforementioned resolution, Copel GeT’s transmission asset RAPs for the 2020-2021 cycle were R$777.2 million, of which R$703.4 million correspond to the revenue of operational assets. Considering the homologated RAPs for the Special Purpose Companies (Sociedades de Propósito Específicos) in which Copel GeT has equity ownership, the total consolidated value for Copel GeT is R$1,146.0 million. Along with beginning of commercial operations of Mata de Santa Genebra assets in its totality in 2020, GeT’s total consolidated value is R$1,161.2 million.

The table below shows our APR (R$ million) for the last four cycles of transmission lines over which we hold a 100% ownership:

Other Businesses

Telecommunications

Copel Telecomunicações S.A. Pursuant to an authorization from the Brazilian National Telecommunication Agency (Agência Nacional de Telecomunicações – “ANATEL”), we provide telecommunication services within the States of Paraná and Santa Catarina. We have been offering these services since August 1998 through the use of our fiber optics network (totaling 36.2 thousand km of fiber optic cables by the end of 2020). In addition, we have been involved in an educational project aimed at providing broadband internet access to public elementary and middle schools in the State of Paraná.

COPEL currently serves 399 municipalities in the State of Paraná. All of these municipalities are connected to COPEL’s optical backbone.

In addition to the high transmission capacity in its backbone, Copel Telecom serves 85municipalities in the State of Paraná, with GPON (Gigabit-Capable Passive Optical Networks) access technology, providing several network services with symmetry rates, in different types of Fts services.

We provide services to most of the major Brazilian telecommunication companies that operate in the State of Paraná. In total, we have corporate clients that include supermarkets, universities, banks, internet service providers and television networks in addition to retail clients. We also provide a number of different telecommunication services to our subsidiaries.

On November 9, 2020, Copel Telecom's divestment auction was held at B3 S.A. - Brasil, Bolsa, Balcão. The winning bid was R$ 2.4 billion (equity value). On January 14, 2021, a Share Purchase Agreement for 100% of Copel Telecom was entered into with Bordeaux Multi-Strategic Investment Fund – Bordeaux Fundo de Investimentos em Participações Multiestratégia, the winning bidder of the auction. We estimate that the transaction will close between the second or third quarter of 2021.

Sercomtel. Sercomtel S.A. (“Sercomtel”) holds a concession to provide fixed telephony services and an authorization to provide mobile services in the municipalities of Londrina and Tamarana, located in the State of Paraná. In addition, Sercomtel has two (2) other authorizations from ANATEL that allow it to provide fixed telephony and broadband internet services in all other municipalities of the State of Paraná. Currently, Sercomtel operates with its own network in fifteen (15) municipalities of the State of Paraná, providing voice services and fixed broadband. Pursuant to a commercial agreement between COPEL and Sercomtel in force since March 2012, Sercomtel can provide voice services over Copel Telecom’s network in one hundred and eighty three (183) cities within the State of Paraná, including Curitiba. .

In addition to the telecommunications business, Sercomtel S.A. – Telecomunicações currently holds the following equity interest: (i) 100% of the capital stock of Sercomtel Participações S.A., a company whose purpose is to provide added value services, design, deploy and maintain internet service providers, operate a service center for users of telecommunications services, offer integrated IT solutions, among other activities. In September 2017, pursuant to Decision (Acórdão) no. 366, ANATEL determined that Sercomtel was not in compliance with certain financial indicators set forth by the agency in connection with the concessions granted to Sercomtel and required for the company’s operations to continue. As a consequence, ANATEL brought an administrative proceeding against Sercomtel to assess whether the concession and the authorizations granted to this company should be terminated. In March 2019, ANATEL decided to suspend the above mentioned proceeding, so that Sercomtel could present to the agency alternative plans for meeting the relevant regulatory indicators. ANATEL published a bidding notice proposal in September 2019 with respect to the licenses held by Sercomtel. ANATEL’s proposal is subject to review by the Federal Audit Court (Tribunal de Contas da União). No bidding process has been carried out by ANATEL, as of the date hereof. If a bidding process is indeed carried out by ANATEL, Sercomtel’s licenses could be forfeited and terminated.

Sercomtel had losses in previous years and faced financial difficulties in carrying out its operations. Given the accumulated losses and the uncertainties regarding its operational viability, we carried out in 2013 the write-off of this investment in our financial statements.

In June 2019, the municipal legislature of Londrina approved the sale of the stake held by the Londrina City Hall as the controlling shareholder of Sercomtel (Municipal Law No 12.871, dated June 12, 2019). In November 2019, the City Hall published the bidding notice for the privatization process of Sercomtel, which provided for the assignment of the City Hall’s preemptive right to subscribe shares in a future capital increase of Sercomtel. This process would result in the dilution of the stake held by the City Hall and Copel in Sercomtel. However, given that no bidders attended the February 5, 2020 auction, a new date was scheduled for July 9, 2020.

On August 18, 2020, Sercomtel’s privatization auction was held at B3 S.A. - Brasil, Bolsa, Balcão.

The winner of the auction pledged to make an investment of R$130 million in Sercomtel, in order to meet Anatel's minimum indicators and end the process of forfeiture of its concession and forfeiture of its authorization grants.

On December 23, 2020, the operation was closed, and Copel received R$1.5 million for its share.

Gas

Gas Distribution

We are engaged in the distribution of natural gas through Companhia Paranaense de Gás (“Compagas”), the company that holds the exclusive rights to supply piped gas in the State of Paraná. Compagas operates the gas distribution grid in the State of Paraná under a concession agreement with a term of 30 years, with expiry on July 6, 2024. Such date has always been announced and considered for assessment of the balances of the prior-year financial statements. The concession agreement may be extended for an equal 30-year period upon request of the concessionaire.

On December 7, 2017, however, the State of Paraná published Supplementary Law 205, introducing a new interpretation of the expiry of the concession, which should have occurred on January 20, 2019. Notwithstanding the new expiration date provided by the state law, this concession has not been subject to neither an extension nor a new bidding process. Pursuant to applicable law, Compagas, as the current concessionaire, may continue to operate the concession until a new concessionaire is appointed.

45

In addition, the management of Compagas, we and other shareholders are challenging the effects of the aforesaid law, understanding that it conflicts with the provisions of the concession agreement currently in force. Compagas filed a lawsuit challenging the anticipating of the expiration date of such concession and was granted with a provisional remedy on October 30, 2018, which granted a preliminary injunction in our favor to recognize the validity of clause 1.1 of the Concession Agreement, which establishes a contractual term of 30 years as of July 6, 1994, ending on July 6, 2024. We await a decision in the judicial process.

Furthermore, Supplementary Law No. 227/2020 was published on December 4, 2020, which amended Supplementary Law No. 205/2017, revoking its article 15, which provided for the end of the concession term on January 20, 2019. Despite the revocation, the lawsuit remains in progress to have the validity of clause 1.1 of the Concession Agreement judicially declared. Compagas covered 842 kilometers in 2020, increase of 1.1% compared to 833 kilometers covered in 2019. Compagas’s net revenues were R$524.2 million, a decrease of 30.7%, compared to 2019 (R$756.6 million), and its net income was R$59.6 million, a decrease of R$126.4 million or 68% compared to 2019. Compagas’ customers include industries, gas stations, other businesses and residences and Araucária Thermoelectric plan. Compagas is focusing its business strategy on increasing the volume of gas it distributes to customers by marketing the benefits of substituting oil and other fuels by gas as a mean of achieving greater energy efficiency. Compagas’ customer base increased 4.4%, to 49,335 customers in 2020 from 47,238 in 2019.

Compagas registered an decrease of 35.6% in the average daily volume of natural gas distributed to Final Customers, to 881,745 cubic meters per day in 2020 (not including the volume of gas supplied to Araucária Thermoelectric Plant) compared to 1,368,915 cubic meters per day in 2019 (not including the volume of gas supplied to Araucária Thermoelectric Plant). In addition, Compagas makes its distribution grid available to transport natural gas to Araucária TPP. The volume of natural gas supplied from Petrobras and distributed by Compagas to Araucária TPP, was 676,113 cubic meters per day in 2020, compared to 68,050 cubic meters per day in 2019.

As of December 31, 2020, we held a controlling stake (51%) of the capital stock of Compagas and consolidated this equity interest in our financial statements. The minority shareholders of Compagas are Petrobras, through its subsidiary Gaspetro, and Mitsui Gás, each of which owns 24.5% of the capital stock of Compagas.

Gas Exploration

In the 12th bidding round of National Petroleum Agency (Agência Nacional do Petróleo “ANP”), held at the end of 2013, the consortium formed by us (30%), Bayar Participações (30%), Tucumann Engenharia (10%) and Petra Energia (30%), the latter acting as operating company, won the right to explore, research, develop and produce oil and natural gas in four blocks located in the central southern region of the State of Paraná, in a 11,327 km² area. The minimum investment in the first phase of the research is approximately R$78.1 million for a 4-year term. We and our partners have signed the concession contracts for 2 blocks in May 2014. However, because of a public civil action, the first phase of exploration for these two blocks was halted and the signing of the other two concession contracts was prohibited. On June 7th, 2017, a court decision held that all the bidding round and the agreements related thereto should be deemed null and void. Moreover, the Government of the State of Paraná enacted Law No. 19,878 (July 3, 2019), forbidding the exploration of shale gas through the drilling / fracking method.

As a result of the above-mentioned events, our consortium requested ANP to release it from its contractual obligations, with no liabilities and with reimbursement of the signing bonuses, reimbursement of all costs incurred in connection with guarantees and release of such guarantees for the four blocks. Even though this request was submitted to ANP on September 6th, 2017, it is still subject to analysis. All the activities for the four blocks were interrupted due to the suspension of the effects of the12th bidding round of ANP because of an injunction granted in connection with the above mentioned public civil action, which awaits a decision from the Federal Court of Appeals of the 4th Region. For this reason, in October 2018, the consortium approved the establishment of an institutional arbitration procedure with the ANP for the four blocks awarded in the 12th bidding round of ANP, asking for the refund of the contributions made. Arbitral proceedings have already been initiated.

Gas Natural Power Plants

On January 14, 2020, Copel and Shell Brasil Petróleo formed the "Copel Energia a Gás Natural" Consortium with the objective of developing feasibility studies for natural gas power plants in the state of Paraná. The consortium hired a consulting firm to provide specialized technical services to carry out studies to identify the best location for the implementation of natural gas thermoelectric projects in the State. The study is ongoing.

CONCESSIONS

We operate under concessions granted by the Brazilian government for our generation, transmission and distribution businesses. Under Brazilian law, concessions are subject to competitive bidding processes at the end of their respective terms.

2013 Concession Renewal Law

Until 2013, the Brazilian rules governing generation concessions gave concessionaires the right to renew for additional 20 year concession contracts that were entered into prior to December 11, 2003. For transmission and distribution concessions granted after 1995, concessionaires had the right to renew these contracts for an additional 30-year period.

On September 11, 2012, the Brazilian government enacted the Provisional Measure No. 579, subsequently converted into the 2013 Concession Renewal Law, which significantly changed the conditions under which concessionaires are able to renew concession contracts. Under the 2013 Concession Renewal Law, generation, transmission and distribution concessionaires may renew the concessions that were in effect as of 1995 (and, in the case of generation facilities, generation concession contracts entered into prior to 2003) for an additional period of 30 years (or an additional 20-year period in the case thermal plants), provided that the concessionaire agrees to amend the concession contract to reflect a series of new conditions that aim to ensure that services are provided in a continuous and efficient fashion and subject to low tariffs. Under the 2013 Concession Renewal Law, concessionaires must decide 60 months before the end of each concession term (or 24 months with respect to thermal plant concessions that it is 24 months) whether to amend and renew a concession contract or to terminate each concession contract at the end of its respective term.

For concessionaires of generation facilities existing at that time, the 2013 Concession Renewal Law changed the scope of the concession contracts at the moment they were renewed. Previously, a generation concessionaire had the right to sell the energy generated by the facilities subject to its concession for profit. In contrast, generation concessions renewed pursuant to the 2013 Concession Renewal Law do not grant concessionaires the right to sell the energy generated by these facilities. Instead, these concessions only cover the operation and maintenance of the generation facilities, subject to quality standards determined by Brazilian authorities. The energy generated by these facilities are allocated by the Brazilian government in quotas to the regulated market, for purchase by distribution concessionaires. For new generation facilities (i.e., generation facilities operated after the 2013 Concession Renewal Law), on the other hand, the concessionaire still has the right to sell the energy produced by the generation facility.

In addition to changing the scope of generation concessions, the 2013 Concession Renewal Law establishes a new tariff regime that significantly affects the treatment of amounts to be invested by concessionaires to improve and maintain generation plants. To this effect, several regulations were issued by MME and ANEEL to regulate the compensation due to concessionaires as a result of their investments to improve and maintain generation plants.

The 2013 Concession Renewal Law affects transmission and distribution concessions differently. The principal change is that amounts invested in modernization projects, structural reforms, equipment and contingencies are subject to prior ANEEL approval. However, the 2013 Concession Renewal Law does not affect the manner in which distribution and transmission concessionaires may recover amounts invested in transmission infrastructure.

With respect to the transmission agreements, the conditions for renewal set forth in the 2013 Concession Renewal Law are the acceptance of a fixed income as determined by ANEEL and compliance with quality standards set forth in applicable regulation. With respect to distribution agreements, the conditions are set forth in the amendment to the concession agreement and are related to compliance with quality standards, economic-financial sustainability indicators and corporate governance as set forth in the amendment to the concession agreement according to the parameters provided in the 2013 Concession Renewal Law.

47

The 2013 Concession Renewal Law applies to all generation, transmission and distribution contracts that were in effect as of 1995 (and, in the case of generation concessions, entered into prior to 2003), regardless of whether a contract grants to the concessionaire the right to renew a concession on its original terms. For example, several of our concession contracts contain provisions allowing us to renew these concessions for a period of 20 years. Under the 2013 Concession Renewal Law, in order to renew these contracts, we nonetheless would be required to accept the application of the conditions imposed by the 2013 Concession Renewal Law to the contract, and the concession contract would then be renewed for 30 years, rather than 20 years. If we choose to renew a concession contract that contains a renewal provision, we would be indemnified by the Brazilian government using funds from the RGR Fund (see Energy Sector Regulatory Charges) in an amount equal to the portion of our investments related to the concession that have not yet been amortized or depreciated, as calculated by ANEEL.

If a concessionaire decides not to accept the new tariff regime with respect to a concession contract and therefore decides not to renew the contract, the concession will terminate at the end of its original term, and the Brazilian government will conduct a new competitive bidding process for the concession. The original concessionaire may participate in the new competitive bidding process.

In the case of hydroelectric generation concessions with an installed capacity of more than 5,000 kW, upon the expiration of their original term and provided that the concessionaire does not request the extension of such term, the granting authority may submit the concession to a new bidding process. In the case of concessions for hydroelectric generation units with an installed capacity of 5,000 kW or less, upon the expiration of their original term, the concessions may be granted to the current concessionaire in the form of registration, for an indefinite term.

Generation Concessions

Of the nineteen (19) hydroelectric plants we operated in 2020, fourteen (14) were operated under the generation concession contracts that were in force prior to the 2013 Concession Renewal Law, and five (5) were operated in accordance with the 2013 Concession Renewal Law (Capivari Cachoeira HPP, Chopim I HPP, Marumbi HPP, Baixo Iguaçu HPP and Colíder HPP). In 2013, 12 of the 13 hydro and thermoelectric generation concessions operated by the Company in 2013 (exception made only to Rio dos Patos HPP) were extended pursuant to the old regime and could be renewed again under the 2013 Concession Renewal Law.

However, at the time the 2013 Concession Renewal Law was enacted, the Company elected not to renew the following generation concessions: Rio dos Patos (2014), Mourão I (2015), Chopim I (2015) and Capivari Cachoeira (2015), all of which had remaining terms of 60 months or less. Please see below for further information on each of these concessions.

Foz do Areia HPP. Copel Geração e Transmissão did not elect to renew the original concession pursuant the 2013 Concession Renewal Law for the Foz do Areia HPP (Governador Bento Munhoz da Rocha Netto). However, in order to obtain a new concession for the Foz do Areia HPP for another 30 years, Copel GeT transferred the ownership of this HPP to its subsidiary, the SPC F.D.A. Geração de Energia Elétrica S.A (F.D.A) on March 3, 2020, and, on the same date, requested a new concession from the Ministry of Mines and Energy pursuant to Federal Decree no. 9,271/2018 (as amended by Federal Decree no. 10,135/2019), which conditions that, to obtain a new concession, the sale of the concession's corporate control (F.D.A) must occur. On the same date, F.D.A. signed with ANEEL the Concession Contract that transfers the concession of the HPP Foz do Areia from Copel GeT to the F.D.A., for the exploration of the plant until the end of the current concession, on September 17, 2023.

Rio dos Patos HPP. The concession of Rio dos Patos HPP was terminated and not submitted to a further bidding process due to the lack operational conditions.

Mourão I and Capivari Cachoeira HPP. The granting authority submitted the concessions for HPP Capivari Cachoeira and Mourão I to new bidding processes, pursuant to which new agreements should be in force for a 30-year period. Copel GeT was the winner in the bidding process related to HPP Capivari Cachoeira. With respect to Capivari Cachoeira, although Copel GeT did not elect to renew the original concession for the Capivari Cachoeira HPP, it participated in the new competitive bidding process and won. On January 5, 2016, Copel GeT executed a concession agreement with ANEEL so that it will continue to operate this plant under an operation and maintenance regime until 2046. We paid a total amount of R$574.8 million as signing bonus for this concession agreement. 100.0% of the energy generated by this plant in 2016 was allocated in quotas to the regulated market, and reduced to 70.0% on January 1, 2017. Copel GeT can sell remaining amount of energy generated by this plant on the Free Market or Spot Market.

Chopin I HPP. As the installed capacity of Chopin I HPP also does not exceed 5,000 kW, the concession regime of this plant has been changed to a registration in favor of the Company, valid for an indefinite term. In addition, pursuant to the same statute, we may notify the granting authority of its intention to extend: (i) in 2020, the concession of Apucaraninha HPP; and (ii) in 2021, the concessions of Guaricana and Chaminé HPPs. In the event we do not request the extension of these concessions, they will be subject to new bidding processes conducted by the granting authority.

Figueira TPP. Our concession for the Figueira TPP expired on March 26, 2019. We had filed an extension request with respect to this plant on May 24, 2017, but we are still waiting for the granting authority to amnd our concession agreement, extending its term for an additional 20-year period in accordance with the 2013 Concession Renewal Law. This plant has an installed capacity equivalent to 20 MW and subject to a modernization process.

With respect to the concessions granted between 2011 and 2017 with no renewal right attached, we acquired the right to renew only one of the hydroelectric plants (HPP Cavernoso II) for a 30-year period, as a result of an amendment to the 2013 Concession Renewal Law by Law No. 13,360, of November 17, 2016.

In accordance with the 2013 Concession Renewal Law, Copel could have flagged to the granting authority by 2019 its intention to renew the concession of HPP São Jorge. However, Copel elected not to renew such concession and, consequently, it will be able to operate such HPP until December 2024 and request the conversion of this operating regime into a registration regime, as the installed capacity does not exceed 5,000 kW.

Concessions for generation projects granted after December 11, 2003 were not affected by the 2013 Concession Renewal Law and are non-renewable, meaning that upon expiration of their 35-year term, the concession will be granted subject to a new competitive bidding process. In 2019, we had three (3) hydroelectric plants operating in this condition (HPP Mauá, HPP Colíder and HPP Baixo Iguaçu).

In September 2020, the GSF Law was passed, which established new conditions for the renegotiation of hydrological risk of electricity generation, amending Article 2 of Law No. 13,203/2015, among other measures. This procedure was regulated through Normative Resolution No. 895/2020, in which ANEEL established the methodology for calculating compensation to the owners of hydroelectric plants participating in the MRE. It also regulated the repatriation of hydrological risk to equate the issue of GSF and open debts in CCEE to allow for the return of normalcy and greater liquidity in the short-term electricity market, in exchange for the extension of the terms of grants given to hydroelectric plants to up to seven years.

On March 2, 2021, CCEE released the calculations of the renegotiation of the hydrological risk and the results, which total approximately R$ 1,366.3 million for the 15 eligible plants of the Company, were sent to Aneel to be submitted to the approval analysis. To date, the Company has not yet adhered to the renegotiation of the hydrological risk, as the Management is awaiting approval by Aneel of the approximately 510 days of average extension of the granting of its plants to assess the possible adherence to the terms of the renegotiation and waiver of future questions or lawsuits in relation to the hydrological risks in question. More information is detailed as described in notes 1-b to our audited consolidated financial statements.

The following tables sets forth information relating to the actual terms as well as the renewals of our main generation hydroelectric, thermoelectric and wind farm plants and all of which we hold a direct ownership interest in:

Transmission Concessions

Pursuant to the 2013 Concession Renewal Law and the terms of our transmission concessions, we have the right to request 30-year extensions of the concessions from ANEEL, provided that such request is delivered within 60 months prior to the expiration of the contract. Our principal transmission concession, from which 72% of our transmission revenues in 2020 derived, has been renewed pursuant to the 2013 Concession Renewal Law, and will therefore now expire in December 2042.

In addition, in 2020, an aggregate of 28% of our transmission revenues derived from eleven (11) other concession contracts for transmission lines and substations that are currently in operation and whose terms and extensions are set forth in the next table. In accordance with the 2013 Concession Renewal Law, each of these contracts can be extended for an additional 30-year period.

We intend to continue requesting extensions for all of our transmission concessions.

The following table sets forth certain information relating to the terms and extension terms of our main transmission concessions (all of which we hold a direct ownership interest), including the concession contracts for transmission lines and substations both in operation or under construction:

Distribution Concessions

We originally operated our distribution business pursuant to a concession contract that was signed on June 24, 1999 (retroactive to July 7, 1995), and was set to expire on July 7, 2015. Under the 2013 Concession Renewal Law, we had the right to renew this concession for an additional 30-year period by accepting an amendment to the concession contract. Notwithstanding the changes introduced by the 2013 Concession Renewal Law, we concluded that the renewal of our distribution concession in accordance with the 2013 Concession Renewal Law would not materially affect our results of operations. Accordingly, after a careful evaluation of the conditions imposed by the Brazilian government for the extension of our distribution concession, we decided to request the renewal of this contract and our renewal request was approved by the MME on November 11, 2015. On December 9, 2015, we have executed the fifth amendment to the public Electricity Distribution Service Concession Agreement No. 46/1999 of Copel Distribuição S.A.

This amendment imposes efficiency conditions to Copel Distribuição that are measured through two different metrics: quality of the service and economic-financial sustainability of the company. Failure to comply with any of these metrics (i) for two consecutive years within the first four years of this renewed concession or (ii) in the fifth year of this concession, may, in each case, result in the termination of our distribution concession. From January 1, 2021 on, failure to comply with the quality indicator for three consecutive years or the economic-financial sustainability indicator for two consecutive years may also result in the termination of the distribution concession.

Additionally, non-compliance with quality indicator targets for two consecutive years or three times in five years may lead to restrictions in the payment of dividends and interest on equity to the controlling shareholders of Copel Distribuição, while non-compliance with the economic-financial sustainability indicators may require capital contributions from Copel Distribuição controlling shareholders.

The table below presents the economic and financial and quality indicators established for the first five (5) years after the execution of this amendment.

| Economic and Financial Indicators | Quality Indicators (1)
Year |  | DECi(2) | FECi(2)
2016 | N/A | 13.61 | 9.24
2017 | EBITDA(3) ≥ 0 | 12.54 | 8.74
2018 | [EBITDA (-) QRR (4)] ≥ 0 | 11.23 | 8.24
2019 | {Net Debt(5)/[EBITDA(3) (-) QRR(4)]} ≤ 1/(0.8*SELIC(6)) | 10.12 | 7.74
2020 | {Net Debt(5)/[EBITDA(3) (-) QRR(4)]} ≤ 1/(0.8*SELIC(6) 1/(1.11*SELIC(6)) | 9.83 | 7.24

___________________

(1) According to ANEEL’s Technical Note No. 0335/2015.

(2) DECi – Duration of outages per customer per year (in hours); and FECi – Frequency of outages per customer per year (number of outages).

(3) Earnings before interest, tax depreciation and amortization, as calculated according to ANEEL regulations.

(4) QRR: Regulatory Reintegration Quota or Regulatory Depreciation Expense. This is the value defined in the most recent Periodic Tariff Review (RTP), plus the General Market Price inflation index (IGP-M) between the month preceding the Periodic Tariff Review and the month preceding the twelve-month period of the economic and financial sustainability measurement.

(5) As calculated according to ANEEL regulations.

(6) Selic base rate: limited to 12.87% per year.

We have complied with the quality indicators for 2019 both with respect to DECi totaling 9.10 in 2019) and FECi (totaling 6.0 in 2019).

COMPETITION

We have concessions to distribute electricity in substantially all of the State of Paraná, and we do not face competition from the four utilities that have been granted concessions for the remainder of the state. As a result of legislation passed in 2004, however, other suppliers are able to offer electricity to our existing Free Customers at prices lower than those we currently charge. However, when a Captive Customer becomes a Free Customer, it is still required to pay to use our distribution grid. The reduction in net revenue of our distribution business is therefore compensated with a reduction in our costs for energy that we would otherwise acquire to sell to these customers.

Furthermore, under certain circumstances, Free Customers may be entitled to connect directly to the Interconnected Transmission System rather than our distribution grid. Unlike a Free Customer’s choice of another energy supplier, in which case that customer must still use our distribution grid and thus pay us the appropriate tariff, our distribution business ceases to collect tariffs from a customer that connects directly to the Interconnected Transmission System. The migration of customers from the distribution grid to the transmission network therefore results in the loss of revenues for our distribution business.

Distribution and transmission companies are required to permit the use of their lines and ancillary facilities for the distribution and transmission of electricity by other parties upon payment of a tariff.

Free Customers are limited to, as from January 1, 2021, with demand of at least 1.5 MW; after January 1, 2022, customers with demand of at least 1.0 MW at any voltage; and, after January 1, 2023, with demand of at least 500 kW at any voltage.

Special customers are costumers with demand of at least 500 kW that opt to be supplied energy by means of alternative sources, such as wind power projects, small hydroelectric power plants, biomass projects, solar plants and others.

As of December 31, 2020, we had 912 Free Customers (of which of 877 were customers of our energy trading company and 35 of Copel GeT), representing approximately 8.0% of our consolidated operating revenue and approximately 14.9% of the total quantity of electricity sold by us.

Copel GeT has 35 Free Costumers as of December 31, 2020. Approximately 55.2% of the megawatts-hours sold under contracts to such customers by Copel GeT expired in 2020. These customers represented approximately 6.3% of the total volume of electricity we sold in 2020, and approximately 3.2% of our consolidated operating revenues.

In the generation business, any producer may be granted a concession to build or manage thermoelectric and small hydroelectric generating facilities in the State of Paraná. Brazilian law provides for competitive bidding for generation concessions for hydroelectric facilities and, since 2017, this requirement applies only to facilities with capacity higher than 50 MW.

In the transmission business, Brazilian law provides for competitive bidding for transmission concessions for facilities with a voltage of 230 kV or greater that will form part of the Interconnected Transmission System.

Brazilian law requires that all of our generation, transmission and distribution concessions be subject to a competitive bidding process upon their expiration. We may face significant competition from third parties in bidding for renewal of such concessions or for any new concessions. The loss of certain concessions could adversely affect our results of operations

ENVIRONMENT

Our construction and operation activities for the generation, transmission and distribution of electric energy, distribution of natural gas and our telecommunications operations are subject to federal, state and municipal environmental regulations.

All of our activities follow our Sustainability Policy, which integrates corporate planning and sustainability management in order to optimize our financial, social and environmental performance. Also, our activities follow our Climate Change Policy, which establishes guidelines for the mitigation of greenhouse gas emission and changes in our business, evaluating risks and opportunities related to climate change.

We request and renew our environmental licenses in accordance with the environmental regulation issued by applicable federal, state and municipal level authorities. We are in compliance with all material environmental regulations and our more recent (post-1986) generation, transmission and distribution projects are in compliance with federal, state and municipal regulations.

Being a signatory to the Global Compact since 2000, we are committed to sustainability.

PLANT, PROPERTY AND EQUIPMENT

Our principal properties consist of the generation and telecommunications facilities described in “Business”. Of the net book value of our total property, plant and equipment as of December 31, 2020 (including construction in progress), generation facilities represented 64.4%, wind farms represented 30.1%, telecommunications represented 0.5%, Elejor represented 3.7%, and Araucária Thermoelectric Plant represented 1.3%. We believe that our facilities generally are adequate for our present needs and suitable for their intended purposes.

In addition, the infrastructure used by the transmission and distribution business is classified as accounts receivable related to the concession, contract assets and intangible assets as described in Notes 4.4, 4.5 and 4.9 to our audited consolidated financial statements.

56

THE EXPROPRIATION PROCESS

Although we receive concessions from the Brazilian government to construct hydroelectric facilities, we do not receive title to the land on which the facilities are to be located. In order for us to construct, the land must be expropriated. The land required for the implementation of a hydroelectric facility may only be expropriated pursuant to specific legislation, after proving its public interest. We generally negotiate with communities and individual owners occupying the land so as to resettle such communities in other areas and to compensate individual owners. Our policy of resettlement and compensation generally has resulted in the settlement of expropriation disputes, with friendly settlements for most of them. As of December 31, 2020, we estimated our liability related to the settlement of such disputes to be approximately R$ 133.9 million. This amount is in addition to amounts for land expropriation included in each of our hydroelectric facility budgets.

The Brazilian eLECTRIC Power Industry

General

In February 2021, according to Ordinance No. 002/2021, MME approved the Decennial Energy Plan - PDE 2030, which projects that the installed capacity of electricity generation in Brazil will be 196 in GW in 2030 (not including distributed generation and self-production). It is projected in the 2021 PDE that 87% of this total will be renewable (54% is projected to be hydroelectric and 29% will be alternative sources of energy, such as wind, biomass and small hydroelectric plants), 11% will be thermoelectric, 4% will be solar, and 2% will be nuclear.

As of 2020, approximately 30% of the installed power generating capacity of Brazil is currently owned by Eletrobras (including its wholly-owned subsidiary Eletronuclear and its 50% participation interest in Itaipu). Through its subsidiaries, Eletrobras is also responsible for approximately 44% of the installed transmission capacity equal or above 230 kV within Brazil. In addition, some Brazilian states control entities involved in the generation, transmission and distribution of electricity. They include Companhia Energética de Minas Gerais – CEMIG and us, among others.

Principal Regulatory Authorities

Ministry of Mines and Energy – MME

The MME is the primary regulatory institution of the power industry and acts as the Brazilian governmental authority empowered with policymaking, regulatory and supervisory powers.

National Energy Policy Council – CNPE

The National Energy Policy Council (Conselho Nacional de Política Energética - “CNPE”), created in August 1997, provides advice to the President of the Republic of Brazil regarding the development and creation of a national energy policy. The CNPE is chaired by the MME and is composed of ten ministers of the Brazilian government and five members designated by the President of CNPE. The CNPE was created in order to optimize the use of energy resources in Brazil and ensure the national supply of electricity.

National Electric Energy Agency – ANEEL

The Brazilian power industry is regulated by ANEEL, an independent federal regulatory agency. ANEEL’s primary responsibility is to regulate and supervise the power industry in accordance with the policies set forth by the MME and to respond to matters which are delegated to it by the Brazilian government and the MME. ANEEL’s current responsibilities include, among others, (i) administering concessions for electric energy generation, transmission and distribution, including the approval of electricity tariffs, (ii) enacting regulations for the electric energy industry, (iii) implementing and regulating the utilization of energy sources, including the use of hydroelectric power, (iv) promoting, monitoring and managing the public bidding process for new concessions, (v) settling administrative disputes among electricity sector entities and electricity purchasers, and (vi) defining the criteria and methodology for the determination of transmission and distribution tariffs.

National Electric System Operator – ONS

The ONS (Operador Nacional do Sistema Elétrico) is a non-profit private entity comprised of electric utilities engaged in the generation, transmission and distribution of electric energy, in addition to other private participants such as importers, exporters and Free Customers. The primary role of the ONS is to coordinate and regulate the generation and transmission operations in the Interconnected Transmission System, subject to the ANEEL’s regulation and supervision. The objectives and principal responsibilities of the ONS include, among others, operational planning for the generation industry, organizing the use of the domestic Interconnected Transmission System and international interconnections, ensuring that industry participants have access to the transmission network in a non-discriminatory manner, assisting in the expansion of the electric energy system, proposing plans to the MME for extensions of the Interconnected Transmission System, and formulating regulations regarding the operation of the transmission system for ANEEL’s approval.

58

Electric Energy Trading Chamber – CCEE

The CCEE (Câmara de Comercialização de Energia Elétrica) is a non-profit private entity subject to authorization, inspection and regulation by ANEEL. The CCEE is responsible for, among other things, (i) registering all energy purchase agreements in the regulated market, Contratos de Comercialização de Energia no Ambiente Regulado (“CCEAR”) and in the Free Market, (ii) accounting for and clearing short-term transactions and (iii) managing funds generated by some of the regulatory charges. The CCEE is composed of holders of concessions, permissions and authorizations in the electricity industry and Free Customers, and its board of directors is composed of five members, out of which four are appointed by these agents and one by the MME, who is the chairman of the board of directors.

Energy Sector Monitoring Committee – CMSE

The CMSE (Comitê de Monitoramento do Setor Elétrico) was created by the New Industry Model Law to monitor service conditions and to recommend preventative measures to ensure energy supply adequacy, including demand-side action and contracting of energy reserves.

Energy Research Company – EPE

In August 2004, the Brazilian government created the Energy Research Company (Empresa de Pesquisa Energética - “EPE”), a federal public company responsible for conducting strategic studies and research in the energy sector, including the industries of electric power, petroleum, natural gas, coal and renewable energy sources. The studies and research conducted by the EPE subsidize the formulation of energy policy by the MME.

Eletrobras

Eletrobras serves as a holding company for the following federally-owned energy companies: Companhia Hidro Elétrica do São Francisco – CHESF, Furnas Centrais Elétricas S.A., CGT Eletrosul, Centrais Elétricas do Norte do Brasil S.A. – Eletronorte, Companhia de Geração Térmica de Energia Elétrica – CGTEE and Eletrobras Termonuclear S.A. – Eletronuclear, Centro de Pesquisas de Energia Elétrica – Cepel and Itaipu Binacional. Eletrobras manages the commercialization of energy from Itaipu and from alternative energy sources, under the Program for incentive to alternative energy sources (Programa de Incentivo às Fontes Alternativas de Energia – “Proinfa”).

Historical Background of Industry Legislation

The Brazilian constitution provides that the development, use and sale of electric energy may be undertaken directly by the Brazilian government or indirectly through the granting of concessions, permissions or authorizations. Historically, the Brazilian electric energy industry has been dominated by generation, transmission and distribution concessionaires controlled by the federal or state governments. Since 1995, the Brazilian government has taken a number of measures to reform the Brazilian electric energy industry. in general, these measures were aimed at increasing the role of private investment and eliminating foreign investment restrictions in order to increase overall competition and productivity in the industry.

The following is a summary of the principal developments in the regulatory and legal framework of the Brazilian electricity sector:

| · | In 1995, (i) the Brazilian constitution was amended to authorize foreign investment in power generation; (ii) the Concessions Law was enacted, requiring that all concessions for energy-related services be granted through public bidding processes, providing for the creation of independent producers and Free Customers and granting electricity suppliers and Free Customers open access to all distribution and transmission systems; and (iii) a portion of the controlling interests held by Eletrobras and various Brazilian states in generation and distribution companies were sold to private investors.

| · | In 1998, the Power Industry Law was enacted, providing for, among other things, the creation of the ONS and the appointment of National Bank for Economic and Social Development, or Banco Nacional de Desenvolvimento Econômico e Social (“BNDES”), a development bank wholly owned by the Brazilian government, as the financing agent of the power industry, especially to support new generation projects.

59

| · | In 2001, Brazil faced a serious energy crisis that lasted through February 2002. During this period, the Brazilian government implemented an energy-rationing program in the most adversely affected regions, namely the southeast, central-west and northeast regions of Brazil. In April 2002, the Brazilian government for the first time implemented the extraordinary tariff adjustment to compensate the electricity suppliers for financial losses incurred as a result of the rationing period.

| · | In 2004, the Brazilian government enacted the New Industry Model Law (Law No. 10,848), in an effort to further restructure the power industry with the ultimate goal of providing customers with a stable supply of electricity at reasonable prices. The New Industry Model Law introduced material changes to the regulation of the electric energy industry, in order to (i) provide incentives to private and public entities to build and maintain generation capacity, and (ii) ensure the supply of electricity in Brazil at low tariffs through a competitive electricity public bidding process. The key elements of the New Industry Model Law include:

| o | Ensuring the existence of two markets: (i) the regulated market, a more stable market in terms of supply of electricity, and (ii) a market specifically addressed to certain participants (i.e., Free Customers and energy-trading companies), called the Free Market, that permits a certain degree of competition vis-à-vis the regulated market.

| o | Restrictions on certain distribution activities, including requiring distributors to focus on their core business of distribution activities in order to promote more efficient and reliable services to Captive Customers.

| o | Elimination of self-dealing by providing an incentive for distributors to purchase electricity at the lowest available prices rather than buying electricity from related parties.

| o | Upholding contracts executed prior to the New Industry Model Law, in order to provide regulatory stability for transactions carried out before its enactment.

| · | In 2004, Decree No. 5,163 was enacted to governor the purchase and sale of electricity in the regulated market and the Free Market, as well as the granting of authorizations and concessions for electricity generation projects. This decree includes, among other items, rules relating to auction procedures, the form of power purchase agreements and the mechanism for passing costs through to Final Customers. Among other matters, this decree:

| o | provides for the guidelines under which electricity-purchasing agents must contract their electricity demand. Electricity-selling agents must show that the energy to be sold comes from existing or planned power generation facilities. Agents that do not comply with such requirements are subject to penalties imposed by ANEEL.

| o | requires electricity distribution companies to contract for 100% of their energy needs primarily through public auctions. In addition to these auctions, distribution companies can purchase limited amounts (up to 10% of their demand) from: (i) generation companies that are connected directly to a distribution company (except for hydroelectric power plants with capacity higher than 30 MW and certain thermoelectric power plants) (ii) electricity generation projects participating in the initial phase of the Proinfa Program, (iii) the Itaipu Power Plant and (iv) quotas from those generation concession contracts extended or subject to a new competitive bidding process in accordance with the 2013 Concession Renewal Law.

| o | provides that the MME shall establish the total amount of energy that will be contracted in the regulated market, including the number and the type of generation projects that will be auctioned each year.

60

| o | requires all electricity generation, distribution and trading companies, independent producers and Free Customers to notify MME, by August 1st of each year, of their estimated electricity demand or estimated electricity generation, as the case may be, for each of the subsequent five years. In advance of each electricity auction, each distribution company is also required to inform MME of the amount of electricity that it intends to contract in the auction. In addition, distribution companies are required to specify the portion of the contracted amount they intend to use to supply potentially Free Customers.

| · | In 2012, the Brazilian government enacted two Provisional Measures that brought important changes to the Brazilian electricity regulatory framework: (i) Provisional Measure No. 577, dated as of August 29, 2012 (converted into Law No. 12,767 dated as of December 27, 2012); and (ii) Provisional Measure No. 579, dated September 11, 2012 (converted into the 2013 Concession Renewal Law). Provisional Measure No. 577 established the obligation of the granting authority to render electricity services in the event of termination of an electricity concession, as well as new rules related to the intervention by the granting authority in electricity concessions to ensure adequate performance of Utility services. The 2013 Concession Renewal Law established new rules that changed concessionaires’ ability to renew concession contracts. Under this Law, generation and distribution concessionaires may renew their concession contracts that were in effect as of 1995 and transmission concessionaires may renew their concession contracts that were in effect prior to and as of 1995 for an additional period of 30 years, provided that the concessionaires agree to amend the concession contracts to reflect a new tariff regime to be established by ANEEL. See “—Concessions”.

| · | In 2013, the 2013 Concession Renewal Law was enacted. This statute changed the nature of the concession agreements for generation facilities existing at the time. Prior to 2013, a generation concessionaire had the right to sell the energy generated by the facilities subject to its concession for profit. In contrast, generation concessions for existing generation facilities (including those renewed pursuant to the 2013 Concession Renewal Law) could no longer grant concessionaires the right to sell the energy generated by these facilities. Instead, these concessions started to cover the operation and maintenance of the generation facilities. The energy generated by these facilities was then allocated by the Brazilian government in quotas to the regulated market, for purchase by distribution concessionaires. In case of generation facilities created after the 2013 Concession Renewal Law, the concessionaire has the right to sell the energy produced by the facility. For further information, see “—Concessions—2013 Concession Renewal Law.”

| · | In 2015, the Brazilian government enacted Provisional Measure No. 688, dated as of August 18, 2015, converted into Federal Law No. 13,203, dated as of December 8, 2015, to revise the allocation of the hydrological risks borne by hydroelectric power plants that share hydrological risks under Energy Reallocation Mechanism. In 2014 and 2015, given poor hydrological conditions, the MRE participants generated less electricity than their assured energies, which was confirmed by a significant decrease of the Generating Scaling Factor (“GSF”), a measurement of the proportion between the electricity generated by the MRE participants and their respective assured energy. These generation deficits resulted in losses for the MRE participants given their exposure to hydrological risks. As a consequence, Federal Law No. 13,203 established an optional mechanism that allows each generation plant to transfer these risks to Final Customers upon payment of a risk premium to the Brazilian government, as well as certain temporary extensions of generation concessions to compensate for losses in 2015. We decided to opt-in with respect to all of Copel GeT´s and Elejor´s eligible Energy Agreements under this new hydrological risk allocation mechanism, which represented approximately 16% of Copel GeT´s total assured energy.

| · | In 2016, the Brazilian government enacted Provisional Measure No. 735, dated as of June 22, 2016, converted into Federal Law No. 13,360, dated as of November 17, 2016, which changed several federal laws mainly to: (i) revise certain rules related to regulatory charges (CDE, CCC and RGE) and appoint CCEE as the new manager of such charges in lieu of Eletrobras; (ii) facilitate the privatization of generation, transmission and distribution companies, (iii) change certain requirements of the generation concession and authorization regimes; (iv) change rules related to the MRE; (v) allow distribution companies to sell energy excess in the Free Market; (vi) extension of terms for commencement of the supply under energy auctions in the regulated market; and (vii) transfer back from MME to ANEEL the authority to decide about generation and transmission companies’ requests for extension of their facilities construction schedules.

61

| · | In July 2017, the MME released the Public Consultation No. 033/2017, named “Proposal for improvement of the legal framework of the electricity sector”. This public consultation marks an important step to guide the MME in preparation of specific legislative proposals capable of providing measures of economic rationalization and modernization of the electricity sector.

| · | In August 2017, Decree No. 9,143/2017 changed the frequency of the auctions for new energy and authorized the distribution companies to negotiate contracts for the sale of energy in the Free Market to Free Consumers and other agents (generators, marketers, and self-producers), provided that these contracts are linked to excess in energy contracted in auctions.

| · | In January 2018, Decree No 9,271/2018 regulated the granting of a new energy concession in the event of privatization of an energy generation concession holder that provides public services, in accordance with Law No 9.074, dated July 7, 1995. Pursuant to this decree, the Brazilian government may grant a new concession contract for a period of up to 30 years to the entity that results from a bidding process for the privatization of a concessionaire previously controlled directly or indirectly by a federal, state or municipal governmental entity. This decree determined that the concessionaire shall request a new concession contract during the remaining period of its concession (up to 60 months counted from the end of the concession) This decree was amended in November 2019 pursuant to Decree No 10,135 in order to reduce the deadline for the concessionaire to request the granting of a new agreement, from 60 months to 42 months counted from the end of the concession and required the privatization process to be concluded no later than 18 months prior to the termination of the prior concession.

| · | During 2018, the Brazilian government concluded the privatization of Eletrobras’ distribution companies Companhia Energética do Piauí - Cepisa, Companhia Energética de Rondônia S.A. - Ceron, Companhia de Eletricidade do Acre - Eletroacre, Boa Vista Energia S.A. - Boa Vista Energia, Companhia Energética de Alagoas - Ceal and Amazonas Distribuidora de Energia S.A. - Amazonas Distribuidora.

| · | In June 2019, the National Energy Policy Council (Conselho Nacional de Política Energética – CNPE) launched a program pursuant to its Resolution No. 16 to boost the natural gas market and foster competition by promoting free competition and using Thermoelectric Plants as a vehicle for creating demand for the better use of natural gas from the Pre-Salt layer.

| · | In December 2019, MME published the Ordinance No. 465/2019, determining that MME will gradually decrease, over the next years, the power limits to contract electric power by consumers served at any voltage, allowing them to purchase energy from conventional sources, considering the following schedule: (i) from January 1, 2021: consumers with demand equal to or greater than 1,500 kW; (ii) from January 1, 2022: consumers with demand equal to or greater than 1,000 kW; and (iii) January 1, 2023: consumers with demand of 500 kW or more. Furthermore, by January 31, 2022, ANEEL and CCEE shall present studies on the regulatory measures necessary to allow the opening of the Free Market for consumers with electric load below 500 kW.

| · | In January 2020, the ONS implemented the Short Term Hydrothermal Dispatch Model (Modelo de Despacho Hidrotérmico de Curtíssimo Prazo - DESSEM), in order to optimize the operations of National Interconnected System (Sistema Interligado Nacional – SIN), and to reduce the difference between the planned dispatch and the one that is actually carried out by taking into account factors related to the electric grid, the operation of hydroelectric power plants, Thermoelectric Plants and other sector components. The execution of DESSEM meets the schedule set forth in Ordinance MME nº 301, dated July 31, 2019.

| · | In September 2020, Law No. 14,052 (the “GSF Law”) was passed, which established new conditions for the renegotiation of hydrological risk of electricity generation, amending Article 2 of Law No. 13,203/2015, among other measures. This procedure was regulated through Normative Resolution No. 895/2020, in which ANEEL established the methodology for calculating compensation to the owners of hydroelectric plants participating in the MRE. It also regulated the repatriation of hydrological risk to equate the issue of GSF and open debts in CCEE to allow for the return of normalcy and greater liquidity in the short-term electricity market, in exchange for the extension of the terms of grants given to hydroelectric plants to up to seven years.

62

| · | In December 2020, through Normative Resolution No. 905/2020, ANEEL consolidated the rules for Electric Energy Transmission Services in the National Electric System, effective January 1, 2021.

| · | In January 2021, the CCEE adopted an hourly pricing model for the accounting and settlement of the short-term market. Thus, since January 1, 2021, the PLD is officially calculated for each submarket on an hourly basis, per the implementation schedule defined by MME Directive 301/2019.

| · | Additionally, 2020 was atypical due to the COVID-19 pandemic, which required the introduction of various legal and regulatory measures, as highlighted below:

| o | In March 2020, Decree No. 6 officially declared a state of emergency in Brazil, effective until December 31, 2020. On the same date, Decree no. 10,282 was released (complemented by Decree No. 10,288/2020), which regulated Law No. 13,979/2020 and dealt with the new COVID-19 measures, including directives regarding the operation of public services and essential activities, specifically the electricity sector and electricity generation, transmission and distribution. By means of Decree No. 117/2020, the MME also established a Crisis Committee within the Ministory’s scope to articulate, coordinate, monitor, guide and supervise the measures and actions taken against COVID-19 for the duration of the public health crisis. In line with the guidelines established by this decree, ANEEL issued Decree No. 6,335/2020, the Office of Monitoring the Electrical Situation (Gabinete de Monitoramento da Situação Elétrica), with the objective of identifying the effects of the COVID-19 pandemic on the electrical energy market and monitoring the economic-financial situation in relation to supply and demand, as well as coordinating studies of proposals to preserve equilibrium between different entities within the sector.

| o | In March 2020, to ensure the continuity of electricity distribution services, ANEEL issued Normative Resolution No. 878/2020, solidifying the Agency's first measures in order to guarantee the supply of electricity to certain consumer units that have lost the ability to remain compliant as a result of the COVID-19 pandemic. This especially concerns consumer units related to the supply of energy to services and activities considered essential, as defined by Federal Decrees No. 10,282/2020 and No. 10,288/2020.

| o | On April 8, 2020, the Brazilian government issued Provisional Measure No. 950, which specified temporary emergency measures for the electricity sector to cope with the state of emergency by establishing an exemption in energy tariffs funded by the CDE for low-income consumers for up to 220 kWh/month, for the period of April 1 to June 30, 2020. For this purpose, resources were provisioned by means of a credit operation aimed at providing financial relief to electricity distributors. On the same date, ANEEL published Order No. 986, authorizing the CCEE to transfer the surplus financial resources available in the reserve fund for future relief to the sector's agents, based on consumption, with the aim of reinforcing the sector's liquidity in the midst of the COVID-19 pandemic.

| o | On May 18, 2020, Decree No. 10,350 was issued by the Brazilian government, which regulated Provisional Measure No. 950/2020 and provided for the creation of the COVID-19 Fund. This fund was to receive resources to cover potential deficits or anticipate distributors' revenues and regulate the use of tariffs by the CDE for the purpose of payments and receipts of amounts to cover or defer costs arising from the COVID-19 pandemic. Through Resolution No. 885/2020, ANEEL established criteria and procedures for the management of the COVID-19 Fund. The value of the resources of the COVID-19 Fund given to concessionaires were made operational by the CCEE throughout 2020, considering, for this purpose, the existence of a positive balance in the fund.

63

| o | In May 2020, by means of Order No. 1,511/2020, ANEEL, suspended the systematic application of the system for activating the Tariff Flags (Bandeiras Tarifárias), under exceptional and temporary circumstances, as provided for in Submodule 6.8 of the Procedures for Tariff Regulation. This added a “green flag” through December 31, 2020 in accordance with the time period stipulated in Federal Decree No. 10,350/2020 to cover the electric sector’s costs with resources from the COVID-19 Fund. This was in effect until November 30, 2020, when it was revoked by ANEEL with the same-day issuance of Order No. 3,364/2020.

| o | Finally, in September 2020, Provisional Measure No. 998/2020 was issued, due to important changes in the electricity sector rules to mitigate the effects on the consumer due to aid granted to companies as a result of the COVID-19 pandemic, such as transferring 30% of the funds that concessionaires are required to invest in research and development and energy efficiency programs between 2021 and 2025. Notwithstanding these points, this measure also sought to address the withdrawal of incentives for renewable sources, removing the discount on the tariffs for the use of the transmission (TUST) and distribution (TUSD) systems for projects such as small hydroelectric plants and plants based on solar sources, wind power, biomass and qualified cogeneration. These incentives are only being maintained for projects that apply for the concession within twelve months of September 1, 2020 and the start of operations of all its Generating Units within 48 months from the date of concession. In addition, Provisional Measure No. 998 contemplated several other changes in the regulation of the sector, such as the reallocation of resources to reduce energy tariffs for consumers in northern Brazil. Regarding the measure’s effectiveness, it is important to highlight that after being approved by the House of Representatives on December 17, 2020 and by the Federal Senate on February 4, 2021, being sanctioned in March 2021 by the President of the Republic, through Law 14.120, of March 1, 2021.

Potential New Regulatory Framework

The following potential changes to the Brazilian regulatory framework may have a direct impact in our operations, as our business is subject to comprehensive regulation by various Brazilian legal and regulatory bodies, especially the MME (which proposes sector policies) and ANEEL (which regulates, supervises and inspects various aspects of our business, including our tariff rates).

| · | In February 2018, the MME published on its website a report of the public hearing, reflecting the final proposal for improvements to the energy regulatory framework, which were especially motivated by technological, social and environmental matters, as well as difficulties arising from the current business models. Among the discussed topics, the following stand out:

| o | Termination of the quota system applicable to hydropower plants (HPP) concessions that have been extended or granted through competitive biddings, in accordance with Federal Law No. 12,783/2013, and allocation of part of the economic benefit of grants to the CDEin order to reduce what is charged to the population;

| o | Lowering the minimum thresholds for accessing the Free Market;

| o | Approach between the short-term price formation and the operating cost of the system;

| o | Whether energy and ballast (currently combined for commercialization purposes) should be segregated;

| o | Effects of the migration of consumers to the Free Market;

| o | Market for environmental attributes;

| o | Attraction of foreign capital for investments in the Brazilian energy sector;

64

| o | More efficient tariff discounts;

| o | Allocation of resources from the global reversion reserve to the transmission segment;

| o | Guidelines for the use of research and development resources;

| o | Modernization of the regulated market; and

| o | Reduction of judicial disputes regarding the hydrological risk.

| · | In May 2018, most of the improvements proposed by the MME with respect to the regulatory framework applicable to the energy sector were included in Bill No. 1,917/2015 of the House of Representatives, known as the bill for the energy bill portability (Projeto de Lei da Portabilidade da Conta de Luz). This bill is still subject to analysis in the House of Representatives and, if approved, will depend on further approval by the Senate and the President of Brazil.

| · | Also, there are initiatives in order to promote the modernization of the energy sector. Ordinance MME No. 187/2019 established a working group in order to develop proposals for the modernization of the energy sector, which released a report in October, 2019 with measures that should be adopted or studied, including topics such as (i) opening of the consumer market; (ii) pricing mechanism for the short-market; (iii) expansion of the Free Market accommodating new technologies and new business models; (iv) Energy Reallocation Mechanism; (v) cost and risk allocation; (vi) introduction of new technologies; and (vii) sustainable distribution services. This working group has been appointed for a 2-year term, which may be extended for 1 additional year.

| · | In November 2019, the Brazilian government submitted to Brazilian Congress Bill No. 5,877, which, among other matters, address the privatization of Centrais Elétricas Brasileiras S.A. - Eletrobras. Such bill determines the privatization of Eletrobras pursuant to a capital increase and public offering of new common shares (that entitle their holders to voting rights), resulting in the dilution of the stake held by the Brazilian government in Eletrobras (the “Eletrobras Privatization”). In February 2021, Provisional Measure No. 1,031/2021 on the Eletrobras Privatization was issued.

| · | In November 2019, ANEEL submitted a proposed amendment to Resolution No. 482/2012 to a public hearing. This resolution refers to the distribution of micro and mini energy generation. The update of such rules was required in 2015 by Resolution 687/2015 and suggests improvements to the credit compensation system in view of changes to distributed generation in recent years.

| · | In December 2019, CNPE approved its Resolution No. 29, pursuant to which (i) it reviewed the general criteria adopted with respect to supply guarantee in studies on offer expansion, planning of the SIN operations, and calculations of energy physical guarantees and power of a generation project. However, MME shall determine the specific thresholds for such criteria, which is used in the calculation of physical guarantees and plans for expansion.

| · | In 2020, due to the COVID-19 pandemic, discussions beginning in 2017 between the MME and the electric sector with regards to proposals for the industry’s improvement of the legal and regulatory framework were interrupted. This meant limited progress on measures such as PL No. 1.917/2015 and PLS No. 232/2016, which address issues such as the commercial model of the electric sector, the portability of electricity bills and concessions for electric energy generation. The COVID-19 pandemic also allowed for compromise within Special Commission of the House of Representatives, established in August 2019, regarding the Brazilian Electric Energy Code, which aims to consolidate electricity legislation that is currently scattered between ordinances issued by various government agencies.

These potential changes to the regulatory framework applicable to the Brazilian Energy Sector may impact our operations in the coming years.

Concessions

The companies or consortia that wish to build or operate facilities for generation, transmission or distribution of electricity in Brazil must participate in a competitive bidding process or must apply to the MME or to ANEEL for a concession, permission or authorization, as the case may be. Concessions grant rights to generate, transmit or distribute electricity in a specific concession area for a specified period. This period is 35 years for generation concessions granted after 2003, and 30 years for new transmission or distribution concessions. In accordance with the 2013 Concession Renewal Law, generation and distribution concessionaires may renew their concession contracts that were in effect as of 1995 and transmission concessionaires may renew their concession contracts that were in effect prior to and as of 1995 for an additional period of 30 years, provided that the concessionaires agree to amend the concession contracts to reflect certain new terms and conditions established by the law. The 2013 Concession Renewal Law does not impact generation concessions granted after 2003, as they are non-renewable.

The Concessions Law establishes, among others, the conditions that the concessionaire must comply with when providing electricity services, customers’ rights and the respective rights and obligations of the concessionaire and the granting authority. In addition to the Concessions Law, the concessionaire must also comply with the general regulations governing the electricity sector. The main provisions of the Concessions Law and related ANEEL regulations are summarized as follows:

Adequate service. The concessionaire must render adequate service to all customers in its concession and must maintain certain standards with respect to regularity, continuity, efficiency, safety and accessibility.

Use of land. The concessionaire may use public land or request that the granting authority expropriate necessary private land for the benefit of the concessionaire. In the latter case, the concessionaire must compensate the affected private landowners.

Strict liability. The concessionaire is strictly liable for all damages arising from the provision of its services.

Changes in controlling interest. The granting authority must approve any direct or indirect change in the concessionaire’s controlling interest.

Intervention by the granting authority. The granting authority may intervene in the concession, through ANEEL, to ensure the adequate performance of services, as well as the full compliance with applicable contractual and regulatory provisions. Once ANEEL determines the intervention, limited to one year, but extendable for additional two years, it must designate a third party to manage the concession. Within 30 days of the determination of the intervention, the granting authority’s representative must commence an administrative proceeding in which the concessionaire is entitled to contest the intervention. The administrative proceeding must be completed within 1 year. The shareholders of the concessionaire under intervention must submit to ANEEL, within 60 days of the determination of the intervention, a recovery and correction plan. If ANEEL approves such plan, the intervention is terminated. In the event ANEEL does not approve the plan, the granting authority may: (i) declare forfeiture of the concession; (ii) determine the spin-off, incorporation, merger or transformation of the concessionaire, incorporation of a subsidiary or assignment of quotas/shares to a third party; (iii) determine the change of control of the concessionaire; (iv) determine a capital increase of the concessionaire; or (v) determine the incorporation of a special purpose company.

Termination of the concession. The termination of the concession agreement may occur by means of expropriation and/or forfeiture. Expropriation is the early termination of a concession for reasons related to the public interest. An expropriation must be specifically approved by law or decree. Forfeiture must be declared by the granting authority after ANEEL or the MME has made a final administrative ruling that the concessionaire, among other things, (i) has failed to render adequate service or comply with an applicable law or regulation, (ii) no longer has the technical, financial or economic capacity to provide adequate service, or (iii) has not complied with penalties assessed by the granting authority. The concessionaire may contest any expropriation or forfeiture in the courts.

A concession agreement may also be terminated (i) through the mutual agreement of the parties, (ii) upon the bankruptcy or dissolution of the concessionaire, or (iii) following a final, non-appealable judicial decision rendered in a proceeding filed by the concessionaire.

When a concession agreement is terminated, all assets, rights and privileges that are materially related to the rendering of electricity services revert to the Brazilian government. Following termination, the concessionaire is entitled to indemnification for its investments in assets that have not been fully amortized or depreciated, after deduction of any amounts due by the concessionaire related to fines and damages.

66

Expiration. When the concession expires, all assets, rights and privileges that are materially related to the rendering of the electricity services revert to the Brazilian government. Following the expiration, the concessionaire is entitled to indemnification for its investments in assets that have not been fully amortized or depreciated as of the expiration.

Penalties. ANEEL regulations govern the imposition of sanctions against electricity sector participants and determine the appropriate penalties based on the nature and importance of the breach (including warnings, fines, temporary suspension from the right to participate in bidding procedures for new concessions, licenses or authorizations and forfeiture). For each infraction, the fines can be up to 2% of the revenue (net of value-added tax and services tax) of the concessionaire in the 12-month period preceding any penalty notice. Some infractions that may result in fines relate to the failure to request ANEEL’s approval to, among other things: (i) execute certain contracts between related parties; (ii) sell or assign the assets related to services rendered as well as impose any encumbrance (including any security, bond, guaranty, pledge and mortgage) on these or any other assets related to the concession or the revenues from electricity services; (iii) effect a change in the controlling interest of the holder of the authorization or concession; and (iv) make certain changes to the bylaws. In the case of contracts executed between related parties that are submitted for ANEEL’s approval, ANEEL may seek to impose restrictions on the terms and conditions of these contracts and, in extreme circumstances, require that the contract be rescinded.

Parallel Environment for the Trading of Electric Energy

Under the New Industry Model Law, the purchase and sale of electricity is carried out in two different segments: (i) the regulated market, which contemplates that distribution companies will purchase by public auction all the electricity they need to supply their customers; and (ii) the Free Market, which provides for the purchase of electricity by non-regulated entities (such as the Free Customers and energy traders).

However, the electricity arising from the following is subject to specific rules different from the rules applicable to the regulated market and to the Free Market: (i) low capacity generation projects located near consumption points (such as certain co-generation plants and small hydroelectric power plants), (ii) plants qualified under the Proinfa Program, an initiative established by the Brazilian government to create incentives for the development of alternative energy sources, such as wind power projects, small hydroelectric power plants and biomass projects, (iii) Itaipu, (iv) Angra 1 and 2 as from 2013 and (v) those generation concession contracts extended or subject to a new bidding process in accordance with the 2013 Concession Renewal Law.

The electricity generated by Itaipu will continue to be sold by Eletrobras to the distribution concessionaires operating in the South, Southeast and Midwest portions of the Interconnected Transmission System. The rates at which Itaipu-generated electricity is traded are denominated in U.S. dollars and established pursuant to a treaty between Brazil and Paraguay. As a consequence, Itaipu rates rise or fall in accordance with the variation of the real/U.S. dollar exchange rate. Changes in the price of Itaipu-generated electricity are, however, subject to the Parcel A cost recovery mechanism discussed as follows under “–Distribution Tariffs”.

Beginning January 2013, the energy generated by nuclear plants Angra 1 and 2 started to be sold by Eletronuclear to the distribution concessionaires at a rate calculated by ANEEL.

The New Industry Model Law does not affect Bilateral Agreements entered into before 2004.

The Regulated Market

In the regulated market, distribution companies must purchase their expected electricity requirements for their Captive Customers in the regulated market through a public auction process. The auction process is administered by ANEEL, either directly or through the CCEE, under certain guidelines provided by the MME.

67

Electricity purchases are generally made through three types of Bilateral Agreements: (i) Energy Agreements (Contratos de Quantidade de Energia), (ii) Availability Agreements (Contratos de Disponibilidade de Energia) and (iii) allocation of energy quotas, as defined by the ANEEL. Under an Energy Agreement, a generator commits to supply a certain amount of electricity and assumes the risk that its electricity supply could be adversely affected by hydrological conditions and low reservoir levels, among other conditions, which could interrupt the supply of electricity. In such case, the generator would be required to purchase electricity elsewhere in order to comply with its supply commitments. Under an Availability Agreement, a generator commits to making a certain amount of capacity available to the regulated market. In such case, the generator’s revenue is guaranteed and the distributors must bear the risk of a supply shortage. With respect to the third method (introduced by the 2013 Concession Renewal Law), the plants that have had their concession renewed under the 2013 Concession Renewal Law lost the right to sell their energy, and from now on will only receive compensation under the energy quota system as a result of the operation and maintenance of such facilities. As a result, energy generated by these generation concessionaires are passed on to distributors at a lower cost through quotas that match the size of the markets served.

With respect to the generation plants with expired concessions, which are subject to a new competitive bidding process, the winner of the competitive bidding process may be required to allocate up to 100% of the energy generated by this plant in quotas to the regulated Market depending on the criteria adopted in the relevant auction process.

The estimate of demand from distributors is the principal factor in determining how much electricity the system as a whole will contract. A distributor is obligated to contract all of its projected electricity needs. A deviation in actual demand from projected demand could result in penalties to distributors. In the event of under-contracting, the distributor is penalized directly in an amount that increases as the difference between the amounts of energy contracted for and actual demand increases. An under-contracting distributor must also pay to meet its demand by purchasing energy in the Spot Market.

In the event of over-contracting, where the contracted volume falls between 100% and 105% of actual demand, the distributor is not penalized and the additional costs are compensated customers’ tariffs. Where the contracted volume is over 105% of actual demand, the distributor must sell energy in the Spot Market. If the contract price proves lower than the current Spot Market price, the distributor sells its excess energy for a profit. On the other hand, if the contract price is higher than the Spot Market price, the distributor sells its excess energy at a loss. The Federal Law No. 13,360, dated November 17, 2016, also permitted the sale of excess energy by distribution companies in the Free Market. Resolutions No. 833, dated December 4, 2018 and 904, dated December 8, 2020, have recently provided additional rules on the methodology to be adopted by distribution companies with respect to the Mechanism of Surplus Sales (Mecanismo de Venda de Excedentes, or MVE).

With respect to the granting of new concessions, regulations provide that bids for new hydroelectric generation facilities may include, among other things, the minimum percentage of electricity to be supplied in auctions in the regulated market. Concessions for new generation projects, such as Mauá and Colíder in our case, are non-renewable, meaning that upon expiration, the concessionaire must again complete a competitive bidding process.

The Free Market

The Free Market covers transactions between generation concessionaires, Independent Power Producers – IPPs, self-generators, energy traders, exporters and importers of electric energy and Free Customers. The Free Market also covers bilateral agreements between generators and distributors signed under the old model, until they expire. Upon expiration, such contracts must be executed under the New Industry Model Law guidelines.

A consumer that is eligible to choose its supplier may only do so upon the expiration of its contract with the local distributor and with advance notice or, in the case of a contract with no expiration date, upon 15 days’ notice in advance of the date on which the distributor must provide MME with its estimated electricity demand for the year. In the latter case, the contract will only be terminated in the following year. Once a consumer has chosen the Free Market, it may only return to the regulated system with five years prior notice to its regional distributor, provided that the distributor may reduce such term at its discretion. This extended period of notice seeks to assure that, if necessary, the distributor can buy additional energy in auctions on the regulated market without imposing extra costs on the captive market.

Private generators may sell electricity directly to Free Customers. State-owned generators may sell electricity directly to Free Customers but are obligated to do so only through private auctions carried out by the state-owned generators exclusively to Free Customers or by the Free Customers.

68

As mentioned above, recently, Federal Law No. 13,360, dated November 17, 2016, also permitted the sale of excess energy by distribution companies in the Free Market, but the effectiveness of the rule is still subject to further regulation by ANEEL.

Focusing on the future of the electricity sector, the Ministry of Mines and Energy launched Public Consultation No. 33/2017 with the purpose of obtaining the view of different participants around improvements in the business model of the sector. Issues such as the expansion of the Free Market and removal of barriers to the entry of its participants, hourly energy price, adequate allocation of risks, security of supply and socio-environmental sustainability were discussed. Further regulation is expected for the years to come with bills being discussed in the Brazilian Congress in order to implement reforms in the power sector. For more information see “–Potential New Regulatory Framework”.

Regulation under the New Industry Model Law and further rules enacted

A July 2004 decree governs the purchase and sale of electricity in the regulated market and the Free Market, as well as the granting of authorizations and concessions for electricity generation projects. This decree includes, among other items, regulations relating to auction procedures, the form of power purchase agreements and the mechanism for passing costs through to Final Customers.

These regulations establish the guidelines under which electricity-purchasing agents must contract their electricity demand. Electricity-selling agents must show that the energy to be sold comes from existing or planned power generation facilities. Agents that do not comply with such requirements are subject to penalties imposed by ANEEL.

These regulations also require electricity distribution companies to contract for 100% of their energy needs primarily through public auctions. In addition to these auctions, distribution companies can purchase limited amounts (up to 10% of their demand) from: (i) generation companies that are connected directly to the distribution company (except for hydroelectric power plants with capacity higher than 30 MW and certain thermoelectric power plants) (ii) electricity generation projects participating in the initial phase of the Proinfa Program, (iii) the Itaipu Power Plant and (iv) quotas from those generation concession contracts extended or subject to a new competitive bidding process in accordance with the 2013 Concession Renewal Law.

The MME establishes the total amount of energy that will be contracted in the regulated market, the number and the type of generation projects that will be auctioned each year.

All electricity generation, distribution and trading companies, independent producers and Free Customers are required to notify MME, by August 1st of each year of their estimated electricity demand or estimated electricity generation, as the case may be, for each of the subsequent five years. In advance of each electricity auction, each distribution company is also required to inform MME of the amount of electricity that it intends to contract in the auction. In addition, distribution companies are required to specify the portion of the contracted amount they intend to use to supply potentially Free Customers.

Auctions in the Regulated Market

Electricity auctions for new generation projects are held from the third to the seventh year before the initial delivery date of electricity. Electricity auctions for existing generation projects are held (i) from the first to the fifth year before the initial delivery date, and (ii) up to four months before the initial delivery date (“Adjustment Auctions”).

New and existing power generators may participate in the Reserve Energy Auctions as long as these generators increase the power system capacity or if they did not achieve commercial operation by January 2008. Invitations to bid in the auctions are prepared by ANEEL in accordance with guidelines established by the MME, including the requirement that the lowest bid wins the auction. Each generation company that participates in the auction executes a contract for the purchase and sale of electricity with each distribution company, in proportion to the distribution companies’ respective estimated demand for electricity, except for the market adjustment and Reserve Energy Auctions.

69

The contracts for new generation projects have a term between 15 and 35 years, and the contracts for existing generation projects have a term between 1 and 15 years. Contracts arising from market Adjustment Auctions are limited to a two-year term. The reserve energy contracts are limited to a 35-year term.

The quantity of energy contracted from existing generation facilities may be reduced for three reasons: (i) to compensate for Captive Customers that become Free Customers; (ii) to compensate for market deviations from the estimated market projections (up to 4% per year of the annual contracted amount, beginning two years after the initial electricity demand is estimated); and (iii) to adjust the quantity of contracted energy in bilateral agreements entered into prior to the enactment of the New Industry Model Law.

With regard to (i) above, the reduction in net revenue caused when a Captive Customer becomes a Free Customer is partially compensated by the increased amounts that Free Customers are required to pay to use our distribution system. However, a Free Customer may disconnect from our distribution grid (and therefore cease to pay us a distribution tariff) if it chooses to connect directly to the Interconnected Transmission System or if it generates energy for self-consumption and transports this energy without using our distribution grid. Because a Free Customer that connects directly to the Interconnected Transmission System no longer pays us a distribution tariff, we might not be able to fully recover this loss in revenues.

Since 2004, CCEE has conducted thirty (30) auctions for new generation projects, twenty two (22) auctions for energy from existing power generation facilities, ten (10) auctions for reserve energy in order to increase energy supply security, three (3) auctions from alternative energy sources and seventeen (17) auctions for market adjustments. No later than August 1 of each year, the generators and distributors provide their estimated electricity generation or estimated electricity demand for the five subsequent years. Based on this information, MME establishes the total amount of electricity to be traded in the auction and determines which generation companies will participate in the auction. The auction is carried out electronically in two phases.

After the completion of the auction (except in the case of Reserve Energy Auction), generators and distributors execute the CCEAR, in which the parties establish the price and amount of the energy contracted in the auction. The price is adjusted annually based on price variations published by the IPCA. The distributors grant financial guarantees to the generators (mainly receivables from the distribution service) to secure their payment obligations under the CCEAR.

Also, after completion of the Reserve Energy Auction, the generation concessionaire and the CCEE execute the Contrato de Energia de Reserva, in which the parties establish the price and amount of the energy contracted for in the auction. The distributors, Free Customers and self-producing customers then execute the Contrato de Uso da Energia de Reserva (“CONUER”) with CCEE, in order to provide for the terms of the use of the reserve energy. The reserve energy customers grant financial guarantees to CCEE to secure their payment obligations under CONUER.

The 2013 Concession Renewal Law established that generation concessions entered into prior to 2003 that were not renewed would be subject to a new competitive bidding process and that the energy generated by these facilities will be allocated by the Brazilian government in quotas to the regulated market, for purchase by distribution concessionaires. On November 25, 2015, ANEEL carried out a competitive bidding process for the grant of new 30-year concessions of 29 hydroelectric plants in accordance with the 2013 Concession Renewal Law. Until December 31, 2016, 100% of the electricity generated by such 29 hydroelectric plants must be destined to the regulated market and, as of January 1, 2017, the percentage was reduced to 70%. On September 27, 2017, the ANEEL carried another competitive bidding process for the grant of new 30-year concessions of 4 hydroelectric plants in accordance with the 2013 Concession Renewal Law. In this auction, the percentage destined to the regulate market was 70% since the beginning of the concession.

The Annual Reference Value

Brazilian regulation establishes a mechanism (“Annual Reference Value”) that limits the costs that can be passed through to Final Customers.

The regulation establishes certain limitations on the ability of distribution companies to pass-through costs to customers, such as no pass-through of costs for electricity purchases that exceed 105% of actual demand.

70

The MME establishes the maximum acquisition price for electricity generated by existing projects. If distributors do not comply with the obligation to fully contract their demand, the pass-through of costs from energy acquired in the short-term market is the lower of the Spot Market price and the Annual Reference Value.

Electric Energy Trading Convention

The Electric Energy Trading Convention (Convenção de Comercialização de Energia Elétrica) regulates the organization and functioning of the CCEE and defines, among other things, (i) the rights and obligations of CCEE participants, (ii) the penalties to be imposed on defaulting agents, (iii) the means of dispute resolution, (iv) trading rules in the regulated and Free Markets, and (v) the accounting and clearing process for short-term transactions.

Restricted Activities of Distributors

Distributors in the Interconnected Transmission System are not permitted to (i) engage in activities related to the generation or transmission of electric energy, (ii) hold, directly or indirectly, any interest in any other company, corporation or strategic agreement, or (iii) engage in activities that are unrelated to their respective concessions, except for those permitted by law or the relevant concession agreement. According to Law No. 13,360/2016, distributors are allowed to sell energy to Free Customers. This possibility is regulated by ANEEL through REH No. 904/2020, with the application of the MVE.

Elimination of Self-Dealing

Since the purchase of electricity for Captive Customers is now performed through auctions in the regulated market, “self-dealing” (under which distributors were permitted to meet up to 30% of their energy needs using energy that was either self-produced or acquired from affiliated companies) is no longer permitted.

Challenges to the Constitutionality of the New Industry Model Law

The New Industry Model Law is currently being challenged on constitutional grounds before the Brazilian Supreme Court. The Brazilian government moved to dismiss the actions, arguing that the constitutional challenges were moot because they related to a provisional measure that had already been converted into law. To date, the Supreme Court has not reached a final decision and we do not know when such a decision may be reached. While the Supreme Court is reviewing the law, its provisions have remained in effect. Regardless of the Supreme Court’s final decision, certain portions of the New Industry Model Law relating to restrictions on distributors performing activities unrelated to the distribution of electricity, including sales of energy by distributors to Free Customers and the elimination of self-dealing, are expected to remain in full force and effect.

Tariffs for the Use of the Distribution and Transmission Systems

ANEEL regulates access to the distribution and transmission systems and establishes tariffs for the use of these systems. The tariffs are (i) network usage charges, which are charges for the use of the proprietary local grid of distribution companies (“TUSD”) and (ii) for the use of the transmission system, which is the Interconnected Transmission System and its ancillary facilities (“TUST”).

TUSD

Users of a distribution grid pay the distribution concessionaire a tariff known as the TUSD (Tarifa de Uso dos Sistemas Elétricos de Distribuição). The TUSD is divided into two parts: one related to the contracted power in R$/kW and another related to the regulatory charges in R$/kWh. The amount paid by the users of a distribution grid is calculated by multiplying the maximum contracted power for each of the customer’s points of connection to the concessionaire’s distribution grid, by the tariff in R$/kW, plus the product of the power consumption by the tariff in R$/kWh, per month.

In relation to the Captive Customers, the TUSD is part of the supply tariff that is calculated based on the voltage used by each customer.

71

TUST

The TUST (Tarifa de Uso do Sistema de Transmissão) is paid by distribution companies, generators and Free Customers to transmission companies for the use of the Interconnected Transmission System (electrical transmission system with a voltage equal or higher than 230 kV). This tariff is revised annually according to (i) the location of the user of the Interconnected Transmission System and (ii) the annual revenues that a transmission company is permitted to collect for the use of its assets in the Interconnected Transmission System. The ONS, an entity that represents all transmission companies that own assets in the Interconnected Transmission System, coordinates the payment of transmission tariffs to these transmission companies. Users of the Interconnected Transmission System sign contracts with the ONS, which allows them to use the transmission grid in return for paying TUST.

Distribution Tariffs

Distribution tariff rates to Final Customers are subject to review by ANEEL, which has the authority to adjust and review these tariffs in response to changes in energy purchase costs and market conditions. When adjusting distribution tariffs, ANEEL divides the costs of distribution companies into (i) costs that are beyond the control of the distributor, (“Parcel A costs”), and (ii) costs that are under control of distributors (“Parcel B costs”). ANEEL’s tariff adjustment formula treats these two categories differently.

Parcel A costs include, among others, the following:

| · | costs of electricity purchased by the concessionaire to attend Captive Customers, in accordance to the regulatory model in force;

| · | charges for the connection to and use of the transmission and distribution grids; and

| · | energy sector regulatory charges.

Parcel B costs include, among others, the following:

| · | a component designed to pay the distributor for the investments made by the distributor on the concession assets;

| · | depreciation costs; and

| · | a component designed to compensate the distributor for its operating and maintenance costs.

Each distribution company’s concession agreement provides annual readjustments. In general, Parcel A costs are fully passed through to customers. Parcel B costs, however, are adjusted for inflation in accordance with the IPCA Index, minus the X factor.

Electricity distribution concessionaires are also entitled to periodic tariff revisions (revisão periódica) every four or five years. In these processes, Parcel B is recalculated, taking into account incentives for efficiency, quality improvement and reasonable tariff. These revisions are aimed at (i) assuring necessary revenues to cover efficient Parcel B operational costs and adequate compensation for investments deemed essential for services provided within the scope of each such company’s concession and (ii) determining the “X factor”. The fifth amendment to our concession agreement, which establishes the renewal of our concession agreement, determines the Periodic Tariff Review every five years.

The X factor for each distribution company is calculated based on the following components:

| · | P, based on the concessionaire’s productivity, which is calculated through the productivity of the distribution segment (PTF), determined by the relation between the variation of the billed market and the operating and capital costs, plus the average growth of the billed market and the consumer units of the concessionaire itself;

72

| · | T, based on the trajectory of the concessionaire’s operating costs, measured as the difference between the cost benchmarks established by ANEEL and the concessionaire’s actual operating costs; and

| · | Q, based on quality target indicators that measure the interruption of energy supply to Final Customers, and other quality indicators.

In addition, a distribution concessionaire may request an Extraordinary Tariff Review of its tariffs in case of evident economic-financial imbalance, according to the admissibility criteria established through the Tariff Regulation Procedures (PRORET), sub-module 2.9. Extraordinary tariff adjustments were granted (i) in June 1999 to compensate for increased costs of electricity purchased from Itaipu as a result of the devaluation of the real against the dollar; (ii) in 2000 to compensate for the increase in Social Security Financing Contribution (Contribuição para o Financiamento da Seguridade Social - COFINS) from 2% to 3%; (iii) in December 2001 to compensate for losses caused by the Rationing Program; (iv) in January 2013, due to the enactment of 2013 Concession Renewal Law; (v) in March 2015, to compensate the costs related to the quotas of the CDE and increased costs with the purchase of energy, and (vi) in March 2017, to compensate the amount unduly included in the tariffs for captive consumers in 2016, referring to the Angra III plant.

Since October 2004, on the date of a subsequent tariff adjustment or tariff revision, whichever occurs earlier, distribution companies have been required to execute separate contracts for the connection and use of the distribution grid and for the sale of electricity to their potentially Free Customers.

Tariff Flags (Bandeiras Tarifárias)

Effective as of January 1, 2015, a new system has been introduced by the ANEEL to permit distribution concessionaires to pass on to their Final Customer certain variable cost increases attributable to changes in hydrological conditions in Brazil, prior to the formal tariffs periodic revisions made by ANEEL.

In accordance with this model, a green, yellow or red flag, as determined by ANEEL, is included in invoices sent to Final Customers, reflecting nationwide hydrological conditions (except for the State of Roraima). If a green flag is added to Final Customers’ invoices due to satisfactory hydrological conditions, no additional charges are added. On the other hand, if these invoices contain yellow or red flags, this indicates that distribution concessionaires are facing higher variable costs from the acquisition of electricity and will pass these costs on to Final Customers.

Incentives

In 2000, a Federal decree created the Thermoelectric Priority Program, (Programa Prioritário de Termoeletricidade, or “PPT”), for the purposes of diversifying the Brazilian energy matrix and decreasing Brazil’s strong dependence on hydroelectric plants. The incentives granted to the Thermoelectric Plants included in the PPT were: (i) guarantee of gas supply for 20 years, as per a MME regulation, (ii) assurance that the costs related to the acquisition of the electric energy produced by Thermoelectric Plants will be passed on to customers through tariffs up to the normative value established by ANEEL, and (iii) guarantee of access to a special BNDES financing program for the electric energy industry.

In 2002, the Brazilian government established the Proinfa Program to encourage the generation of alternative energy sources. Under the Proinfa Program, Eletrobras would purchase the energy generated by alternative sources for a period of 20 years. In its initial phase, the Proinfa Program was limited to a total contracted capacity of 3,300 MW. In its second phase, which should start after the 3,300 MW cap has been reached, the Proinfa Program intends to purchase up to 10% of Brazil’s annual electric energy consumption from alternative sources. The first phase of the Proinfa program commenced in 2004 and it so far has supported the construction of 131 alternative energy plants which is expected to reach the production of 11.2 million MWh. According to a decision of ANEEL, the total investment to the Proinfa Program in 2021 will be R$4.0billion.

Energy Sector Regulatory Charges

EER

The Encargo de Energia de Reserva (“EER”) is a regulatory charge designed to raise funds for energy reserves that have been contracted through CCEE and which are deposited in the Reserve Energy Account (Conta de Energia de Reserva – CONER). These energy reserves, which are mandatory, were created in order to attempt to ensure a sufficient supply of energy in the Interconnected Transmission System. The EER shall be collected from Final Customers of the Interconnected Transmission System. Beginning in 2010, this charge has been collected on a monthly basis.

RGR Fund

In certain circumstances, electric energy companies are compensated for certain assets used in connection with a concession if the concession is revoked or is not renewed. In 1971, the Brazilian Congress created a reserve fund designed to provide these compensatory payments (“RGR Fund”). In February 1999, ANEEL established a fee requiring public-industry electric companies to make monthly contributions to the RGR Fund at an annual rate equal to 2.5% of the company’s fixed assets in service, not to exceed 3% of total operating revenues in any year. Since the enactment of the 2013 Concession Renewal Law, the RGR Fund has been used to fund the compensations arising from the termination of non-renewed concessions. The 2013 Concession Renewal Law also allowed the funds from the RGR Fund to be transferred to the CDE.

According to 2013 Concession Renewal Law, as from January 1, 2013, the concession contracts from concessionaires of (i) distribution; (ii) transmission which competitive bidding process occurred after September 12, 2012; and (iii) transmission and generation which had their concession contract renewed or had their underlying facilities subject to a new competitive bidding process are no longer obliged to pay the annual RGR fee.

UBP

Some hydroelectric generation enterprises (except small hydroelectric power plants) are required to make contributions for using a public asset, Uso de Bem Público (“UBP”) according to the rules of the corresponding public bidding process for the granting of concessions. Eletrobras receives the UBP payments in a specific account. See Note 26 to our audited consolidated financial statements.

ESS

The costs related to maintaining system reliability and stability when Thermoelectric Plants generate energy to meet demand in the National Connection System (SIN) are called System Service Charges, or Encargos de Serviços de Sistema (ESS). These amounts are paid by each entity that purchases energy in the Spot Market (CCEE), proportional to each such entity’s consumption.

ESS is expressed in R$/MWh and paid only to Thermoelectric Plants that generate energy in response to requests by the Electricity System National Operator (ONS).

CDE

In 2002, the Brazilian government instituted the Electric Energy Development Account, Conta de Desenvolvimento Energético (“CDE”). The CDE is funded by (i) annual payments made by concessionaires for the use of public assets, (ii) penalties imposed by ANEEL, (iii) the annual fees paid by agents offering electric energy to Final Customers, by means of an additional charge added to the tariffs for the use of the transmission and distribution grids and (iv) transfer of resources from the Federal General Budget. The CDE was originally created, amongst others, to promote the availability of electric energy services to all of Brazil and the competitiveness of the energy produced by alternative sources.

Currently, CDE aims to fund several public policies in the Brazilian electricity sector, such as: universalization of the electricity service throughout the national territory; granting of tariff discounts to various users of the service (low income; rural; Irrigating; public water, sewage and sanitation services; incentive energy generation and consumption, etc.); low tariff on isolated electricity systems (Fuel Consumption Account - CCC); competitiveness of electricity generation from the national coal source; among others. The CDE is managed by CCEE since May, 2017, pursuant to Federal Law No. 13,360/2016. This charge had been substantially reduced by the 2013 Concession Renewal Law (approximately 75% compared to its December 31, 2011 amount) in an attempt to reduce the cost of electricity paid by Final Customers. The 2013 Concession Renewal Law also allowed the funds from the RGR Fund to be transferred to the CDE, provided that the Federal Treasury would also contribute with the CDE and permit the funds deposited in the CDE to be used in support of the electricity generation program in non-integrated electric grids (sistemas elétricos isolados) as well as to partially offset the increased costs borne by distribution concessionaires for the purchase of energy in the Spot Market as a result of the non-renewal of generation concessions due to the 2013 Concession Renewal Law.

74

On March 7, 2014, the Brazilian government also permitted the transfer to distribution concessionaires of funds deposited in the CDE to cover their respective costs arising from involuntary exposure to the Spot Market in January 2014 as a result of poor hydrological conditions in 2013 and 2014, which mandated the acquisition of thermoelectric energy at higher prices in the Spot Market, costs which distribution concessionaires were not able to pass on to Final Customers through regular Retail Tariffs prior to annual readjustments or formal tariffs periodic revisions made by ANEEL.

Distribution concessionaires will be able to pass on to its Final Customer a CDE charge, to the extent necessary to repay their respective financing obligations contracted by the CCEE through the ACR Account. See “—Regulated Market Account–ACR Account.”

On February 27, 2015, ANEEL approved a significant increase of the CDE fee charged to cover all of these additional costs supported by the CDE. ABRACE, an association of Free Customers filed lawsuits to contest the increase of the CDE fee. Since July 2015, the Free Customers associated with ABRACE benefit from an injunction suspending the increase of the CDE fee. Associations of distributors of energy (ABRADEE, with whom Copel Distribuição is associated) also obtained injunctions suspending its obligation to withhold such CDE fees while ABRACE´s and other consumers’ injunction remains in force.

Federal Law No. 13,360/2016 established that the Brazilian government must prepare a plan for a structural reduction of the CDE charge until December 31, 2017, and it also provided that the revenues, expenses and beneficiaries of the CDE must be published monthly by CCEE, among other changes. As a result, Decree nº 9,642/2018 was published, which determined the gradual reduction, in 5 years, of discounts granted to consumer units classified as Rural and Public Service of Water, Sewage and Sanitation, in Groups A (high voltage) and B (low voltage).

Regulated Market Account – ACR Account.

On April 2014, the Brazilian government created the Regulated Market Account, Conta no Ambiente de Contratação Regulada – Conta-ACR (“ACR Account”), to assist distribution concessionaires to cover their respective costs for the acquisition of thermoelectric energy for the period from February 2014 to December 2014, incurred as a result of poor hydrological conditions. Distributors incurred higher costs as a result of adverse hydrological conditions because they were required to buy thermoelectric energy at higher prices in the Spot Market, and were unable to pass all these costs on to Final Customers prior to a formal tariff periodic revision made by ANEEL. To fund the ACR Account, the Brazilian government authorized the CCEE to enter into credit agreements with certain Brazilian financial institutions. An aggregate of R$21.7 billion, composed of nine tranches, was deposited in the ACR Account. Distribution concessionaires have been repaying this loan since 2015 by charging its Final Customers with additional CDE amounts on a monthly basis. At first, the amount deposited in the ACR Account should be repaid by 2020. However, in March 2019, ANEEL authorized CCEE to negotiate with the creditor financial institutions and seek early termination of the corresponding loans, which occurred in September 2019.

Itaipu Transmission Fee

The Itaipu Hydroelectric Plant has an exclusive transmission grid and is not part of the Interconnected Transmission System. Companies that are entitled to receive electricity from Itaipu pay a transmission fee in an amount equal to their proportional share of the Itaipu generated electricity.

Use of Water Resources Tax

Holders of concessions and authorizations that allow for the exploitation of water resources must pay a total tax of 7.00% of the value of the energy they generate, which for the purposes of this calculation is based on a rate set by ANEEL. Beginning on January 1, 2021, ANEEL set this rate at R$76.00/MWh. The proceeds of this tax are shared among the states and municipalities where the plant or the plant’s reservoir is located, as well as with certain federal agencies.

75

ANEEL Inspection Fee (TFSEE)

The ANEEL Inspection Fee is an annual fee due by the holders of concessions, permissions or authorizations equal to an ANEEL determined percentage of their revenues. The ANEEL Inspection Fee requires these holders to pay up to 0.4% of their annual revenue to ANEEL in 12 monthly installments.

Default on the Payment of Regulatory Charges

The failure to pay required contributions to the RGR Fund, Proinfa Program or CDE or to make certain payments, such as those due from the purchase of electric energy in the regulated market or from Itaipu, will prevent the defaulting party from receiving adjustments or reviews of their tariffs (except for an extraordinary review) and will also prevent the defaulting party from receiving funds from the RGR Fund or CDE. We comply with payment obligations related to Regulatory Charges.

Energy Reallocation Mechanism

The Energy Reallocation Mechanism (Mecanismo de Realocação de Energia, or MRE) attempts to mitigate the risks borne by hydroelectric generators due to variations in river flows (hydrological risk).

Under Brazilian law, each hydroelectric plant is assigned a determined amount of “assured energy”, according to an energy supply risk criterion defined by MME, based on historical river flow records. The assured energy also represents the maximum energy that can be sold by the generator, which is set forth in each concession agreement, irrespective of the volume of electricity actually generated by the facility.

The MRE tries to guarantee that all participating plants receive the revenue corresponding to their assured energy, irrespective of the volume of electricity generated by them. In other words, the MRE effectively reallocates the electricity, transferring the surplus from those who have produced in excess of their assured energy to those that have produced less than their assured energy. The relocation, which occurs in the Interconnected Transmission System, is determined by the ONS, considering the nationwide electricity demand and hydrological conditions, regardless of the power purchase agreement of each individual generator. The volume of electricity actually generated by the plant, whether more or less than their assigned assured energy quotient, is priced pursuant to a tariff known as the “Energy Optimization Tariff”, designed to cover only the variable operation and maintenance costs of the plant, so that generators are largely unaffected by the actual dispatch of their plants.

Each hydroelectric plant which has its concession contract renewed in accordance to 2013 Concession Renewal Law will no longer participate in the MRE, and the hydrological risk from those plants will be borne by the distribution concessionaires under the National Interconnected Power Grid. For the generation plants with expired concessions, which were subject to a new competitive bidding process under the 2013 Concession Renewal Law, 30% of the generated energy available for the generation concessionaire to sell in the market is also subject to the MRE hydrological risk allocation mechanism. This risk does not impact our distribution business, since we are allowed to increase the tariffs of our distribution customers to compensate any costs arising from this hydrological risk.

Research and Development

The companies holding concessions and permissions for distribution of electricity must invest a minimum of 0.50% of their annual net operational revenues in research and development and 0.50% in energy efficiency programs. Beginning on January 1, 2023, these percentages will become 0.75% and 0.25%, respectively.

A company holding concessions and authorizations for generation and transmission of electricity must invest a minimum of 1% of its annual net operational revenues in research and development. A company that generates electricity exclusively from small hydroelectric power plants, cogeneration or alternative energy projects is not subject to this requirement.

The amount to be invested in research and development must be distributed as follows:

76

| · | 40% to the company research and development projects, under the supervision of ANEEL;

| · | 40% to the Ministry of Sciences and Technology, to be invested in national research and development projects; and

| · | 20% to the MME, to defray EPE.

In March 2021, Law 14,120/2021 and ANEEL Resolution 929/2021 changed the allocation of research and development resources.

The amount not yet committed to the research and development program until September 2020 will be transferred to CDE as a way to promote tariff moderateness. In the same way, until December 2025, a minimum of 70% of the percentages defined by law must continue to be invested in research and development programs while the difference will be transferred to CDE.

| · | These measures do not impact the amounts to be invested by the concessionaires, but rather their destination.

Environmental Regulations

The Brazilian Federal Constitution includes environmental matters among the ones that are subject to concurrent legislative competence, meaning that the Brazilian government enacts general rules, which are supplemented by rules passed by states; municipalities, in turn, enact local rules or supplement federal and/or state legislation.

In 1981, the National Environmental Policy was enacted in Brazil (Federal Law No. 6,938/1981). The Federal Environmental Crimes Act (Federal Law No. 9,605/1998), which took effect in 1998, establishes a general framework of liability for environmental crimes. Federal laws and statutes have established the National System for Management of Water Resources and the National Council of Water Resources to address the major environmental issues facing the hydroelectric sector and users of water resources. In 2000, the Brazilian government created an independent agency, the National Water Agency, to regulate and supervise the use of water resources. In 2008, the Federal Decree No. 6,514/2008 was enacted to prescribe the administrative liability due for environmental infractions.

The Brazilian Forestry Code (Federal Law No. 12,651/2012) and related regulations establish rules regarding the maintenance of areas affected by hydroelectric plant reservoirs. These regulations may result in increased maintenance, reforestation and expropriation costs to energy industry concessionaires. We have been developing conservation measures in our power plants, as established in the Brazilian Forestry Code, since their construction.

Under Brazilian environmental Law, one single action that causes risk to the environment can trigger three types of liability: civil, administrative and criminal.

Thus, a violator of an environmental law may be subject to administrative and criminal sanctions and, in case environmental damage occurs, will have an obligation to repair and provide compensation to the affected party. Administrative sanctions may apply to both the company and the individual representatives of the company concomitantly and may include substantial fines of up to BRL 50 million and the suspension of activities. Criminal sanctions may also apply to both company and the individual representatives and include sanctions such as fines for the company and, for individuals including for directors and employees of companies that commit environmental crimes, possible imprisonment.

Our energy generation, distribution and transmission facilities are subject to prior environmental licensing procedures, which may include the preparation of environmental impact assessments before such facilities are constructed, as well as proposing and implementing mitigation and compensation actions for the identified impacts. As a condition for the regularity of these procedures, we must also request authorization from certain regulatory entities, such as Brazilian Institute of National Historic and Artistic Heritage (Instituto do Patrimônio Histórico e Artístico Nacional – IPHAN), an oversight body that is in charge of the protection and preservation of Brazilian cultural heritage (archeological, material and immaterial). Once the respective environmental licenses are obtained, their maintenance is still subject to compliance with certain requirements.

Unitization

On March 11, 2021, acting at an Extraordinary Shareholders’ Meeting, the shareholders of Copel approved the Unitization (as defined below) and amendments to Copel’s bylaws to facilitate the Unitization, including the opening of the period for the Conversion Offers (as defined below) and the terms and conditions of the Conversion Offers. With the Units Program (as defined below), we seek to improve the liquidity of the trading market for our securities by establishing units, each consisting of four Class B Shares and one Common Share (“Units”). The steps to establish the Units, taken as a whole, are referred to as the “Unitization”.

Our bylaws were amended at the shareholders meeting of March 11, 2021 to provide for certain changes in our corporate governance necessary to permit our shares or the Units to be listed in the B3 listing segment known as Level 2. These amendments had previously been approved by the Board of Directors at its meeting on January 20, 2021. The effectiveness of these amendments is conditional on the completion of a public offering by the State of shares or Units owned by it and the listing of Copel on Level 2. When they take effect, these amendments will, among other things, (1) provide for a mandatory tender offer to all shareholders upon specified events, including a change of control, removal from the Level 2 with the exception of a removal for the purpose of Copel’s being listed in Novo Mercado, a special listing segment of B3 listing segment, or termination of registration as a public company under Brazilian law, and (2) provide voting rights for the holders of Preferred Shares (Class A Shares and Class B Shares) on matters involving the transformation, merger or spin-off of Copel.

On March 17, 2021, our Board of Directors approved the 1st Share Conversion and Share Depositary Receipt Formation Program (the “Units Program”).

The Unitization includes the following steps, among others:

| · | From March 22, 2021 to April 20, 2021, of one Common Share and four Class B Shares will be permitted to convert those shares into one Unit (“Standard Conversion Offer”).

| · | For a concurrent period:

| o | A holder of five Class A Shares will be permitted to convert all of them into Class B Shares, subsequently one into a Common Share and those shares to one Unit (the “Class A Share Conversion Offer”).

| o | A holder of five Class B Shares will be permitted to convert one of those shares into a Common Share and then to one Unit (the “Class B Share Conversion Offer”).

| o | Provided that the number of Copel’s Preferred Shares (including Class A Shares) is bellow 2/3 of the total amount of shares, a holder of five Common Shares will be permitted to convert four of those shares into four Class B Shares and then to one Unit (the “Common Share Conversion Offer,” and together with the Standard Conversion Offer, Class A Share Conversion Offer and Class B Share Offer, the “Conversion Offers”).

| · | The Conversion Offers will be conditioned on the aggregate number of Units issuable as a result of the Conversion Offers (taken together) attaining 229.172.878 Units (the “Minimum Participation Condition”), calculated so as to represent approximately 60% of the shares in the free float (excluding shares owned by the State). There is no minimum participation condition that applies separately to any of the Conversion Offer.

| · | The Deposit Agreement governing the Class B ADSs, and the Deposit Agreement governing the American Depositary Shares, each representing one Common Share (the “Common ADSs”), will each be amended to provide that, effective upon completion of the Conversion Offers, there will be a single Deposit Agreement, and each American Depositary Share will represent one Unit (“Unit ADSs”).

If the Conversion Offers are consummated, Unit ADSs will trade on the NYSE, and Class B ADSs will no longer trade on the NYSE. A holder of Class B ADSs or Common ADSs will be able to cancel its ADSs and take delivery of the underlying shares, and it will then be able to hold those shares or tender them into the applicable Brazilian Conversion Offer. Any shares that are not converted will remain outstanding. If a holder has a number of Class B ADSs or Common ADSs that is not an integral multiple of five, the Depositary will sell the excess shares necessary to reduce that number to an integral multiple of five and distribute the cash proceeds to that holder.

78

Share Split

On March 11, 2021, acting at an Extraordinary Shareholders’Meeting, the shareholders of Copel approved the splitting of our shares, pursuant the Brazilian Corporate Law, in the proportion of one share to ten shares, so that for each one share issued by the Company, nine new shares of the same class and type would be credited (the "Share Split"). The shares were traded ex-Share Split as of March 12, 2021 (inclusive), and the shares resulting from the Share Split were credited to the shareholders on March 16, 2021. Considering that the Share Split was carried out in such a way that each share we issued was split into ten shares of the same type and class, there was no surplus resulting from fractions of shares.

The Share Split did not affect our capital stock, which remains at R$10,800,000,000.00 as of March 12, 2021 or impacted any rights of holders of Copel shares. After the Share Split, our capital stock is represented by 2,736,553,750 shares with no par value, of which 1,450,310,800 Common Shares and 1,286,242,950 Preferred Shares and, of these, 3,267,520 are Class A Shares and 1,282,975,430 are Class B Shares. Our management took the necessary measures to implement the Share Split of the ADRs.

Cyber-attacks

On February 1, 2021, a number of our servers suffered cyber-attacks leading to the unavailability of part of our systems. Our systems (Solarwinds) detected the attacks and we immediately followed the security protocols, including suspending the operation of our computerized environment to protect the integrity of the information. Immediately after the event, the Company implemented the Business Crisis Management and Contingency Plan – Cyber-Attack (the “Contingency Cyber Plan”), containing immediate actions to be taken within the scope of a crisis management, and formed an internal Committee to monitor the actions planned. During the assessment of the incident, it was found that the cyber-attack did not have a significant impact on the revenue performance of our business for the year ended December 31, 2020, although it resulted in a small delay in billing in the first days of February 2021 arising from preventive measures to identify the extent of the incident. The incremental expense incurred as a result of the cyber incident was not material, and no provision to be recognized as of December 31, 2020 was identified. It was also found that there was no evidence of destruction, loss, alteration, communication and dissemination of personal data, which rules out any implications for the LGPD.

Although there is no indication that the accuracy and integrity of any financial information and personal data have been affected as a result of the cyber attack incident, we have performed extensive procedures to validate the accuracy and integrity of the information and no access was identified to the computing environment that concentrates our Enterprise Resource Planning (ERP) and billing systems, including in folders and/or files with sensitive personal data. Among the actions set in the Contingency Cyber Plan is the implementation and improvement of policies and internal controls, contributing to the improvement of our information security environment. The competent authorities have been informed about the incident. For more information on our cybersecurity controls, see “Item 3. Key Information―Risk Factors.”

Item 4A. Unresolved Staff Comments

None.

OVERVIEW

Brazilian Economic Conditions

All of our operations are in Brazil, and we are affected by general Brazilian economic conditions. In particular, the general performance of the Brazilian economy affects demand for electricity, and inflation affects our costs and our margins. The Brazilian economic environment faced periods of instability in recent years, impacting the performance of the Brazilian GDP growth rates, with an increase of 2.3% in 2013 and 0.1% in 2014 and a decrease of 3.8% in 2015. The growth rate was equally negative in 2016, with a decrease of 3.3%. The economic environment showed signs of recovery in 2017, with an increase of 1.0% in growth rate. In 2018 and 2019, the economic environment continued to recover, with an increase of 1.3% and 1.1%, respectively, in growth rate. In 2020, the growth rate decreased by 4.1%.

The following table shows selected economic data for the periods indicated:

| Year ended December 31,
| 2020 | 2019 | 2018
Inflation (IPCA) | 4.52% | 4.31% | 3.75%
Inflation (IGP-DI) | 23.7% | 7.70% | 7.10%
Appreciation (depreciation) of the real vs. U.S. dollar | (28.8)% | (4.0%) | (17.13)%
Period-end exchange rate – US$1.00(1) | 5.1967 | 4.0307 | 3.8748
Average exchange rate – US$1.00 | 5.1558 | 3.9461 | 3.6558
Change in real GDP | (4.1)% | 1.1 | 1.3%
Average interbank interest rates(2) | 2.77% | 4.40% | 6.40%

Rates and Prices

Our operational results are significantly affected by changes in the prices at which our generation business sells energy, and by the prices at which our distribution business buys and resells energy.

Our generation business sells energy at unregulated prices in the regulated market, in the Free Market and in the Spot Market. Our generation business allocates the amount of energy that it sells in each of these markets seeking to maximize returns, based on factors such as: (i) the requirements of its concession contracts, many of which set a minimum percentage of energy generated in a particular concession that must be sold in the regulated market; (ii) the volume of energy that we plan to sell to Free Customers for a given year; and (iii) the outlook of the short-term, medium-term and long-term for energy prices generally. Although sales in the Free Market and the Spot Market are not directly regulated, they are influenced by energy regulatory policy. The prices at which our generation business sells energy are not regulated.

Our distribution business purchases enough energy to meet 100% of the demand we forecast for our Final Customers in auctions at unregulated prices in the regulated market. Our distribution business resells that energy to Final Customers at regulated tariffs that take into consideration the price at which the energy was purchased. If our forecasts fall short of the actual electricity demand of our Final Customers, we may be forced to make up for the shortfall by entering into short-term agreements to purchase electricity in the Spot Market. If our forecasts exceed the actual demand of our Final Customers, our distribution business sells the excess energy in the Spot Market. The margins in our distribution business tend to be relatively stable due to the regulated nature of the distribution business, while the margins in our generation business are typically larger but less stable, since they are not substantially market regulated.

Sales to Final Customers (which include sales by our distribution business to Captive Customers, sales by our generation business and sales by our trading business to Free Customers) represented approximately 50.7%of the volume of electricity we made available in 2020, and accounted for 68.7%of our energy sales revenues. Almost all of such sales were to Captive Customers. For more information, see “Item 4. Information on the Company—The Brazilian Electric Power Industry—Distribution Tariffs”. In general, if our costs for energy increase, the tariff process permits us to recover these costs from our customers through higher rates in future periods. However, if we do not receive tariff increases to cover our costs, if the recovery of these costs is delayed, or if our Board of Directors elects to reduce the tariff increase awarded by ANEEL, our profits and cash flows may be adversely affected.

80

ANEEL modifies our Retail Tariffs annually, generally in June. Since January 2013, the adjustments have been as follows.

| · | In January 2013, due to the enactment of 2013 Concession Renewal Law, we were subject to an extraordinary revision that has been approved by ANEEL. The average impact of this extraordinary review in the tariffs we charge our customers was a decrease of 19.28%.

| · | In June 2013, ANEEL approved the annual revision of our Retail Tariffs, increasing them by an average of 13.08%, of which 11.40% related to the tariff increase and 1.68% referred to an increase in recovery of deferred regulatory accounts (CVA). After giving effect to the recovery of Parcel A costs, the average effect of this tariff readjustment on our Captive Customers was an increase of 14.61%. However, Copel Distribuição requested a partial deferral of this adjustment, which was authorized by ANEEL and approved on July 9, 2013. The amount of R$255.9 million was therefore deferred, and included as a financial component in the 2014 annual revision. This deferral reduced the average effect of the tariff adjustment to 9.55%.

| · | In June 2014, ANEEL approved the annual adjustment of our Retail Tariffs, increasing them by an average of 35.38%, of which 25.05% related to the tariff increase and 10.34% related to an increase in recovery of deferred regulatory accounts (CVA). After giving effect to the recovery of Parcel A costs, the average effect of this tariff adjustment on our Captive Customers was an increase of 39.71%. However, Copel Distribuição requested a partial deferral of this adjustment, which was authorized by ANEEL and approved on July 22, 2014. The amount of R$898.3 million was therefore deferred and included as a financial component in the 2015 annual readjustment. This deferral reduced the average effect of the tariff revision to 24.86%.

| · | In March 2015, ANEEL approved an extraordinary revision due to a series of events that significantly impacted the distribution concessionaires’ costs, which were not originally foreseen in the 2014 Retail Tariff increase, such as the increase of Itaipu tariffs (46.14%) and higher prices to purchase energy in recent energy auctions. Copel Distribuição’s Average Tariff revision approved by ANEEL was 36.79% starting from March 2, 2015. Of this total, 22.14% related to CDE charges that have been passed to customers and 14.65% relates to (i) Itaipu’s tariff increase and (ii) the higher prices paid by us to purchase energy in recent energy auctions that have been passed to customers.

| · | In June 2015, ANEEL authorized the annual revision of Copel Distribuição’s tariff to Final Customers, increasing them by an average of 15.32%, of which (i) 20.58% related to the inclusion of the financial components, which will be recovered in the 12 months subsequent to the adjustment (including the amount of R$935.3 million corresponding to the deferrals in 2013 and 2014), (ii) 0.34% related to the restatement of Portion B, (iii) (3.25)% related to the adjustment of Portion A, and (iv) (2.35)% reflected the removal of the financial components from the previous process. The adjustment was fully applied to Copel Distribuição’s tariffs as of June 24, 2015.

| · | In June 2016, ANEEL approved the fourth periodic review of our Retail Tariffs, decreasing them by 12.87%, of which: (1.73)% related to the inclusion of financial components; 4.48% due to the update of Portion B; (2.57)% related to the update of Portion A; and (13.05)% reflecting the removal of the financial components of the previous tariff process.

| · | In March 2017, ANEEL approved an extraordinary tariff revision to correct the amount unduly included in the tariffs for captive consumers in 2016. The return corresponded to the energy that was to be generated by the Angra III power plant; however, the plant was not yet in commercial operation. The refund of the amount charged the most was made in a single installment during the month of April 2017, and, as of May 2017, the tariffs were adjusted to disregard the amount that was being charged. The decision, of extraordinary character, affected 90 distributors of electric power of the country. Copel’s retail tariff was reduced by an average of 11.8% during April 2017, and in May 2017, the tariff was close to its previous value, retaining an average discount of 1.27% until June 2017.

81

| · | In June 2017, ANEEL approved the annual revision of our Retail Tariffs, increasing them by an average of 3.13%, of which 3.86% related to the tariff increase and (0.73)% related to the inclusion of financial components. After the removal of the financial components of the previous tariff process, the average effect of this tariff adjustment on our Customers was an increase of 5.85%.

| · | In June 2018, ANEEL approved the annual revision of our Retail Tariffs, increasing them by an average of 14.32%, of which 7.80% related to the tariff increase and 6.52% related to the inclusion of financial components. After the removal of the financial components of the previous tariff process, the average effect of this tariff adjustment on our Customers was an increase of 15.99%.

| · | In June 2019, ANEEL approved the annual readjustment of our Tariffs, increasing them on average by 8.57%, with -1.96% related to the variation in economic revenue and 10.54% related to the inclusion of financial components. After removing the financial components from the previous tariff process, the average effect of the tariff adjustment on our consumers was an increase by 3.41%.

| · | In June 2020, ANEEL approved the annual readjustment of our supply tariffs, which represented a tariff repositioning index of 15.84%, comprised of a variation of 8.68% in the economic components and 7.16% in the financial components. After removing the effect of the financial variables from the previous tariff process, the average effect perceived by the customers would be 5.39%. However, in an aim to reduce the impact on electric bills due to the financial consequences of the COVID-19 pandemic, ANEEL created the COVID-19 Fund, a loan operation between various banks contracted by the CCEE in order to dilute tariff increases in the next five years. Thus, Copel Distribution asked that the effects the COVID-19 Fund be applied to our annual tariff readjustment in the amount of R$536 million, equivalent to the accumulated total of the Compensation Account for the Variation of Items of Parcel A (CVA), considered a negative financial component, ultimately reducing the effect on the consumer. With the removal of the previous year’s financial components, the final average effect perceived by the consumer was 0.41%.

Purchase and Resale of Energy

Our distribution business purchases energy from generation companies and resells this energy to Final Customers at regulated rates. For more information, see “Item 4. Information on the Company— Business—Generation” and “Item 4. Information on the Company—Business—Purchases for the captive market”. Our major long-term contracts or purchase obligations are described as follows.

| · | We purchase energy from Itaipu at prices that are determined based on the Itaipu project’s costs, including servicing its U.S. dollar-denominated debt. In 2020, our electricity purchases from Itaipu amounted to R$1,766.0 million;

| · | Our distribution business is required to purchase a large portion of its energy needs from the regulated market. For more information, see “Item 4. Information on the Company—The Brazilian Electric Power—Industry—Concessions—Auctions in the Regulated Market”.

Under current legislation, the amount that our distribution business charges Final Customers is composed of two fees: a fee for the actual energy consumed and a fee for the use of our distribution grid. Since the regulated rates at which our distribution business sells energy to Final Customers are substantially the same as the rates at which it purchases energy (after accounting for deductions and the cost of energy purchased for resale), our distribution business does not generate operating profit from the sale of electricity to Final Customers. Rather, our distribution business generates operating profit principally by collecting tariffs for the use of our distribution grid.

Impact of the CRC Account

One of our most significant assets consists of the obligations of the State of Paraná under an agreement that was last amended in October 2017. These obligations derive from amounts we were entitled to recover under a prior regulatory regime, and as a result they are referred to as the recoverable rate deficit account or “CRC Account” (Conta de Resultados a Compensar). The balance is adjusted for IGP-DI, plus interest at 6.65% per year, and is payable in monthly installments until April 2025. If the State of Paraná fails to make payments on a timely basis, we may apply dividends we owe to the State of Paraná in its capacity as our shareholder against amounts it owes us under the CRC Account agreement.

In June 2016, as per the request of the Paraná State Government, our Board of Directors approved an amendment to the CRC Agreement, contingent upon the approval of the Brazilian Department of Treasury, comprising: (i) a grace period from April 2016 to December 2016, in which no principal and interest amounts were paid under the CRC Agreement; and (ii) a grace period from January 2017 to December 2017, in which amounts corresponding exclusively to the interest were paid monthly, but no principal amounts were paid. All other provisions of the CRC Agreement were maintained as they were, including the maintenance of the current correction and interest rates, thus not affecting the global net present value of such agreement.

The Company and the State of Paraná formalized the above-mentioned amendment on October 31, 2017, after the consent from the Brazilian Department of Treasury. The State of Paraná complied with the agreed terms of such amendment and made monthly interest payments until December 2018. As of December 31, 2020, the outstanding balance of the CRC Account was R$1,392.6 million.

As of January 1, 2021, there were 52 monthly installments left. For additional information, see Note 8 to our audited consolidated financial statements.

Special Obligations

The contributions received from the Brazilian government and our customers exclusively for investment in our generation assets, transmission and distribution grid are named as special obligations. We record the amount of these contributions on our statement of financial position as a reduction of our intangible and financial assets, under the caption “special obligations”, and, upon the conclusion or termination of the operating concession granted to us, the amount of these contributions is offset against intangible and financial assets. The amount we recorded as special obligations as of December 31, 2020 was R$2,750.1 million as a reduction of intangible assets and R$29.8million as a reduction of contract assets.

CRITICAL ACCOUNTING POLICIES

In preparing our financial statements, we make estimates concerning a variety of matters as referred to in Note 3.4 to our audited consolidated financial statements. Some of these matters are highly uncertain, and our estimates involve judgments we make based on the information available to us. We have discussed in “Overview” above certain accounting policies relating to regulatory matters. In the discussion below, we have identified several other matters for which our financial information would be materially affected if either (i) we reasonably used different estimates or (ii) in the future we change our estimates in response to changes that are reasonably likely to occur.

The discussion below addresse only those estimates that we consider most important based on the degree of uncertainty and the likelihood of a material impact if we used a different estimate. There are many other areas in which we use estimates about uncertain matters, but the reasonably likely effect of changed or different estimates is not material to our financial presentation. Please see Note 3.4 to our audited consolidated financial statements included herein for a more detailed discussion of the application of these and other accounting policies.

Basis of consolidation

Investments in joint ventures and associations are recognized in the consolidated financial statements based on the equity method and the financial statements of the subsidiaries are included in the consolidated financial statements as from the date they start to be controlled by us until the date such control ceases. Noncontrolling interests are presented in equity, separately from the equity attributable to our shareholders. When required, for calculation of equity in earnings, the investees' financial statements are adjusted to align their policies with our accounting policies.

The analysis of the acquisition of new equity interests is done on a case-by-case basis to determine whether the transaction represents a business combination or an asset purchase and the values ​​of the business combination are recorded using estimates mainly in the definition of the fair value of the acquired equity interest. Transactions between companies under common control do not constitute a business combination. There was no relevant business combination this year.

Financial Instruments

Financial instruments are recognized immediately when the obligation or right arises, at fair value, unless it is a trade receivable without a significant financing component, plus, for an item not measured at fair value through profit or loss, any directly attributable transaction costs. Fair values are determined based on market prices for financial instruments with active market, and by the present value method of expected cash flows, for those that have no quotation available in the market. Please see Notes 4.2 and 35 to our audited consolidated financial statements for more detail about our financial instruments.

Net Sectorial Financial Assets and Liabilities

The amendment to our distribution concession agreement, executed on 2014, provides that, in the event of termination of the concession for any reason, the residual values of Portion A items and other financial components not recovered or returned through tariff are incorporated in the calculation of compensation or deducted from unamortized assets indemnity values. Therefore, we recognize sectorial financial assets and liabilities, considering that the contract protects the concessionaire's right or obligation with the Granting Authority regarding these assets and liabilities.

The balances of the net sectorial financial assets and liabilities, evaluated based on the Company's estimates, comprise: a) Portion A Variation Compensation Account - CVA, which records the variation between estimated and actual energy purchase and transmission costs and sector charges, and b) financial items, which correspond to energy over-contracting, neutrality of charges and other rights and obligations included in the tariff. The final values, included in the tariff, are defined by Aneel. During the year this group of accounts had an impact due to the effects of the Covid Account, as presented in Notes 1 (a) and 9 of our consolidated financial statements.

84

Accounting for Concession Arrangements – Accounts receivable related to the concession, Contract Assets, Intangible Assets and Accounts payable related to the concession

We account for our concession contracts segregated in: Accounts receivable related to the concession, Contract Assets and Intangible Assets, as presented in Notes 4.4, 4.5 and 4.9 to our audited consolidated financial statements. In addition, accounts payable related to the concession are recorded, as presented in Note 4.6 to our audited consolidated financial statements. Estimates and judgments in the valuation of these items are relevant and may cause significant impacts, in view of the representativeness of these balances in our consolidated financial statements.

Concession of electric power distribution

The portion that we recognize as a financial asset refers to the indemnification provided for in the concession agreement for public electricity distribution services that guarantees the unconditional right to receive cash at the end of the concession, to be paid by the granting authority. This indemnification aims to reimburse the Company for investments made in infrastructure, without recovery, through the tariff. We calculate the cash flows linked to these assets considering the value of the tariff base called the Regulatory Remuneration Base - BRR, defined by the granting authority, using the methodology of replacement cost of the assets that are part of the distribution infrastructure linked to the concession.

The portion that we recognize as contract asset represents the contractual right of the concessionaire related to the works under construction to meet the needs of the distribution concession, accounted for at cost plus financial charges, when applicable. When these assets are put into operation, we transfer to the intangible asset the amount equivalent to what will be remunerated by the user through payment of the fee for the use of the services, and for the receivables linked to the concession, the amount equivalent to the residual portion of the assets not amortized which will be reverted to the granting authority through indemnification at the end of the concession.

The portion that we recognize as an intangible asset comprises the right to exploit the infrastructure, built or acquired under the concession regime for the public electric power service, and to charge users for the public service rendered. We record at acquisition cost, including borrowing costs, less accumulated amortization and impairment losses, when applicable. The amortization of this intangible asset reflects the pattern in which we expect the future economic benefits of the asset to be consumed, with amortization expected during the concession term.

Concession of electric power transmission

The portion that we recognize as a contract asset represents the balance of the public electricity transmission service contracts signed with the granting authority to build, operate and maintain the high voltage lines and substations of the generation centers up to the distribution points. During the term of the agreement, we receive, subject to performance, a remuneration denominated Annual Revenue Allowance (RAP) that amortizes the investments made in the construction of the infrastructure and covers the costs of operation and maintenance incurred. After the start of the commercial operation and to the extent that the operation and maintenance service - O&M is provided, the portion of RAP referring to O&M revenue is recognized in profit or loss at fair value, on a monthly basis, and billed together with the revenue part recognized in the construction phase, referring to the remuneration of the built-up assets. This amount billed after complying with the O&M performance is reclassified to the financial asset under Customers until its effective receipt. The revenue in the construction phase is estimated at fair value based on the budgeted cost of the work and used by management as a parameter for bidding on the concession auction. Fair value revenue comprises the budgeted cost for the entire construction period plus the construction margin, which represents sufficient profit to cover the costs of managing and monitoring the work. The remuneration rate of each concession is determined by the projection of the expected cost, of the profit margin on the cost in the construction phase and also of the projection of the RAP to be received in the operational stage, already net of the variable consideration estimate (PV) and the RAP part of the O&M performance. This fair value valuation technique using the income approach discounts cash flow for the entire concession period, determining at initial recognition the implied rate that zeroes the flow over time. This remuneration rate is fixed at the initial period and does not change during the performance of the contract and represents the market rate in effect at the time under the conditions of the negotiation between parties.

The assets arising from the construction of the transmission infrastructure are formed by the recognition of the construction revenue and its financial remuneration. We recognize gains and losses due to efficiency or inefficiency in the construction of the infrastructure and due to periodic tariff review (RTP), when incurred, directly in the statement of income for the year. Upon expiration of the concession, if there is a remaining balance not yet received related to the construction of the infrastructure, it will be received directly from the granting authority, as provided in the concession agreement, as compensation for the investments made and not recovered through RAP.

85

We have not recognized intangible assets for energy transmission concession contracts.

Concession of electric power generation

We recognize as a financial asset the concession agreement for quota generation that provides for the payment of a bonus for the grant, considering that this bonus represents an unconditional right to receive cash, guaranteed by the granting authority during the term of the concession and without risk of demand. The remuneration of this financial asset is based on the weighted average cost of capital (WACC).

We also recognize as financial assets the electricity generation concession contracts that contain clauses for indemnification of the infrastructure not depreciated, amortized and / or received during the term of the concession. At the end of each reporting period, we evaluate the recoverability of the asset, remeasuring its cash flow based on our best estimate.

In intangible assets, we record the onerous concession contract for the generation of electric energy, which corresponds to the acquisition of the right to exploit the hydroelectric power generation potential whose contract provides for payments to the Brazilian government as Use of Public Property - UBP. During the construction of the project, we recognize the amount at the present value of the future cash outflows during the period of validity of the concession agreement. On the date of commencement of the commercial operation of the enterprise, the amount presented is fixed and amortized during the concession period.

We also recognize as an intangible asset the asset constituted by the Generation Scaling Factor (GSF), derived from the excess amount between the amount recovered from the cost and the MRE (GSF) adjustment factor, subtracted from the total cost of the risk premium to be amortized over the period of energy supply in the regulated environment. The amount was transformed by ANEEL into an extension of the grant period, which we amortized on a straight-line basis as from January 1, 2016 until the end of the new concession term.

We did not recognize a contract asset for the power generation concession contracts

Distribution of piped gas

The portion that we recognize as a financial asset is the one that will be indemnified by the granting authority corresponding to the investments made in the ten years prior to the end of the concession provided for in the agreement and which, in Management's opinion, guarantees the unconditional right to receive cash at the end of the concession. We use the indemnification premise based on the replacement cost of the concession assets.

The portion that we recognize as a contract asset comprises the works in progress for the distribution of piped gas which will be transferred to the intangible asset upon its entry into operation and to the extent that the right (authorization) to receive the users is received and the portion that we recognize as an intangible asset corresponds to the users' right to charge for the gas supply. We initially valued this asset at acquisition cost, including interest and other capitalized financial charges. We apply the linear depreciation method based on the estimated useful life of each asset, considering the standard of economic benefit generated by the intangible assets.

Accounts payable related to the concession

We record the amounts set forth in the concession agreement in connection with the right to explore hydraulic power generation potential (onerous concession), whose agreement is signed as Use of Public Property agreements. The obligation is recognized on the date of signature of the concession agreement corresponding to the present value of future cash payments for the concession and, from the on, we remeasure the liability using the effective interest rate and reduced by contractual payments.

Inventories (including property, plant and equipment and contract assets)

We recognize materials and supplies in inventory, classified under current assets, and those assigned for investments, classified under property, plant and equipment, and contract assets, at their average acquisition cost and the amounts do not exceed their net realizable value. We have no impairment recorded in the inventory.

86

Property, Plant and Equipment

We have adopted the deemed cost methodology to determine the fair value of Copel Geração e Transmissão’s property, plant and equipment, specifically for the generation business as of the date of transition of our financial statements to IFRS (January 1, 2009). These assets are depreciated according to the linear method based on annual rates set forth and reviewed periodically by ANEEL, which are used and accepted by the market as representative of the economic useful life of the assets related to concession’s infrastructure, limited to the term of said concession, when applicable. The estimated useful life, the residual amounts, and depreciation are reviewed as of each reporting date, and the effect of any changes in estimates is recorded prospectively, which may have a material impact.to our consolidated financial statements, considering the representativeness of the balance of Property, Plant and Equipment in the total assets of the Company. The assumptions and estimates of impairment of these assets are dealt with in the next item.

Impairment of Assets

Financial assets

Our provisions for losses on financial assets are based on assumptions about default risk, existing market conditions and future estimates at the end of each year.

We estimate the expected credit losses in amounts deemed sufficient to cover potential losses on the realization of customer receivables and others whose recovery is considered unlikely. We account for the balance of expected credit losses based on the credit risk analysis, taking into account specific payment history criteria, recovery actions for credit recovery and the relevance of the amount due in the receivables portfolio. See Notes 4.10.1 and 7.3 to our consolidated financial statements for further details. During this year, this account had impacts due to the coronavirus pandemic, as described in note 1 (a) of our consolidated financial statements.

Non-financial assets

Non-financial assets, primarily property, plants and equipment assets, comprise a significant amount of our total assets. We evaluate our long-lived assets and make judgments and estimates concerning the carrying value of these assets, including the amounts to be capitalized, the depreciation/ amortization rates and useful lives of these long-lived assets. The carrying values of these assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount is not recoverable. This requires us to make long-term forecasts of future revenues and costs related to the assets subject to review. These forecasts require assumptions about the demand for our products and services, future market conditions and regulatory developments. Significant and unanticipated changes to these assumptions could require a provision for impairment in a future period. Please see Notes 4.10.2 and 17.5 to our audited consolidated financial statements for more detail.

Provisions

Our subsidiaries and we are party to certain legal proceedings in Brazil arising in the normal course of business regarding tax, labor, civil and environmental claims.

Provisions are recognized when, and only when: (i) the Company has a present obligation (legal or constructive) resulting from a past event, (ii) it is probable (i.e., more likely than not) that an outflow of resources embodying economic benefits will be required to settle the obligation, and (iii) a reliable estimate can be made of the amount to settle the obligation. By their nature, risks will only be resolved when a future event or events occur or fail to occur. Typically, such events will occur a number of years in the future. The evaluation of these risks is performed by our internal and external legal counsel. Accounting for risks requires significant judgment by management concerning the estimated probabilities, including classification as probable or possible losses and ranges of exposure to potential liability. Management’s assessment of our exposure to risks could change as new developments occur or more information becomes available. The outcome of the risks could vary significantly and could materially impact our consolidated results of operations, cash flows and financial position. For more information, see Note 29 to our audited consolidated financial statements.

87

Revenue Recognition

Revenue from contracts with customers is measured based on the consideration that we expect to receive in a contract with the customer, net of any variable consideration. We recognize revenues when we transfer control of the product or service to the customer and when it is probable to receive the consideration considering the client's ability and intention to pay the consideration when due. We record unbilled revenue, by estimate, when there is no information on the effective revenue incurred.

Interest income is recognized on a straight-line basis and based on time and the effective interest rate on outstanding principal amounts, when it is probable that future economic benefits will flow to us and its amount can be reliably measured.

Revenue related to construction services for infrastructure in the power transmission and distribution services, and gas distribution, are recognized using the percentage of completion method.

Significant changes in the assumptions used for valuing revenue may have a material impact on the Company's results. Additional information is contained in Notes 4.12 and 4.13 to our audited consolidated financial statements.

Construction revenues and costs

We recognize construction revenues and construction costs for construction activities we perform in connection with our distribution and transmission concessions. Our distribution business outsources power distribution infrastructure construction and recognize construction costs and revenues in roughly the same amounts. In contrast, since our transmission business performs much of our transmission infrastructure construction, we recognize construction revenue in amounts that exceed construction costs, resulting in a margin that is calculated based on a methodology that takes into account business risk. Changes in the assumptions to define the construction margin may cause impacts to the consolidated financial statements.

Power purchase and sale transactions in the Spot Market (Electric Energy Trading Chamber - CCEE

We record power purchase and sale transactions in CCEE on the accrual basis of accounting, based on data released by CCEE, which are calculated by the product of the Differences Settlement Prices - PLD multiplied by the energy surplus declared with CCEE, or, when such information is not available in a timely manner, by an estimate prepared by our Management.

Derivative Financial Instruments

We negotiate energy purchase and sale operations and part of our contracts are classified as derivative financial instruments measured at fair value through profit or loss. We recognize in the income for the period unrealized net gains or losses arising from the mark-to-market of these contracts, based on the difference between contracted and market prices.

In addition, we enter into non-deliverable forward contracts, which aim exclusively at providing hedge against exchange rate risks associated with cash flows from capital contributions to subsidiaries, when they reflect foreign-currency denominated purchases of projected equipment. They are measured at their fair value, with changes recorded in the statement of income for the year. The fair value is calculated based on the information of each contracted operation and the respective market information on the closing dates of the financial statements.

Changes in the energy futures price curve and and foreign currency, as well changes in the assumptions for calculating the fair value of these derivatives may have a material impact to the Company’s results. For more information, see Notes 35.2.3 (b) and 35.2.12 to our audited consolidated financial statements.

Taxes

We record Income Tax and Social Contribution and other taxes recoverable and other tax obligations based on applicable law, as described in Note 4.16 to our audited consolidated financial statements.

88

We recognize deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities using prevailing rates. We regularly review our deferred tax assets for recoverability based on its profitability history and the expectation of generating future taxable profits, based on its internal projections prepared for reasonable periods for its business. If we are unable to generate sufficient future taxable income, or if there is a material change in the actual effective tax rates or time period within which the underlying temporary differences become taxable or deductible, we could be required to derecognize all or a significant portion of our deferred tax assets resulting in a substantial increase in our effective tax rate and a material adverse impact on our operating results. Additional information is contained in Notes 4.16.2 and 13.1 to our consolidated financial statements.

Post-employment benefits

We sponsor a (i) defined-benefit pension plan and a (ii) variable contribution pension plan covering substantially all of our employees. We have also established a health care plan for current and retired employees. We determine our obligations for these plans based on calculations performed by independent actuaries using assumptions that we provide about interest rates, investment returns, rates of inflation, mortality rates and future employment levels (see the assumptions and other information about de actuarial valuation in Note 23.5 of our consolidated financial statements). These assumptions directly affect our post-employment benefits liability and any changes may have a significant impact, considering the relevance of the Post-employment benefits amounts in the Company's liabilities.

Leases

We recognize leases at present value as a right-of-use asset and lease liability and, from the initial registration, we record the amortization of the asset and interest on the liability for separately in profit or loss. We use judgments in adopting exemptions from recognition provided for short-term leases (lease term of up to 12 months) and leases of low value assets, so that we record these contracts as operating costs or operating expenses on a straight-line basis during the term of the contract. To estimate the interest rate, we consider the cost of the last fundraising carried out via debentures, disregarding incentivized or subsidized funding. For more information, see Notes 4.18 and 27 to our consolidated financial statements.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 2020, 2019 AND 2018

The following table summarizes our results of operations for the years ended December 31, 2020, 2019 and 2018.

Our consolidated financial statements present our revenue at net value and our operating costs of sales and services provided by function. However, in accordance with IFRS, Note 31 and 32 of our audited consolidated financial statements presents this information according to the nature of the revenue, operating cost or expense. For ease of understanding, the analysis below reflects the information presented by nature.

We highlight that, with the Copel Telecom divestment process approved during the year 2020, we classified the results of this subsidiary as discontinued operations and, for comparability, we restated the balances for 2019 and 2018. Additional information on the divestment process and about the amounts considered as a discontinued operation can be found in Note 40 to our consolidated financial statements.

Besides, in 2020, the economy and our business were affected by COVID-19. Therefore, there was a reduction in electric energy demand in the regulated market, which was affected more intensely in the industrial and commercial consumption classes in the Distribution Company. However, the residential class registered a growth of 5.5% in the year, mainly influenced by measures of social distancing and isolation.

The effects of the pandemic impacted the expected credit losses at Copel, especially in the first semester, due to imposed restrictions, such as the prohibition to cut the energy supply from those defaulter customers. On the other hand, in the second semester, there were lower impacts, due to less restrictions, the recovery of economic activity and the possibility of cutting the energy supply from non-paying customers.

Economic effects of the pandemic on the assumptions of the Company's relevant non-financial assets were individually assessed and concluded, by Management, that it was necessary to adjust the impairment value for some assets. The most significant adjustment occurred at UEG Araucária, considering that its cash flow estimates are affected by the decrease in energy demand in the country, whereas on the other projects there were impairment reversals.

But, despite of the impacts of energy consumption, credit losses and impairmnets, the results of our operation were not materially affected. Further information in Notes 1(a) of our consolidated financial statements,

Results of Operations for 2020 Compared with 2019

Operating Revenues

Our consolidated net operating revenues increased by 17.4% or R$2,764.0 million in 2020 compared to 2019. This result reflected, mainly, an increase of R$1,029.7 million in electricity sales to distributors and of R$721.0 million in sectorial financial assets and liabilities, partially offset by a decrease of R$956.8 million in electricity sales to Final Customers. In addition, there was an increase in the amount of recovery of Pis/Pasep and Cofins on ICMS, recorded within the revenue deductions. Below are the main reasons for variations in revenue accounts:

92

Electricity Sales to Final Customers. Our revenues from electricity sales to Final Customers decreased by 9.1%, or R$956.8 million, , mainly due to a decrease of the average price per kilowatt hour sold to the final customers by Copel Distribuição and the effects of the economic downturn caused by the coronavirus pandemic, as follows:

| · | The revenue from electricity sold to residential customers decreased R$237.5 million in 2020 compared to 2019, also considering a reduction of 5.75% on the average price (R$/MWh) of the electricity sold during the same period, despite the increased volume compared to 2019.

| · | The revenue from electricity sold to industrial customers decreased by 23.9%, or R$305.5 million, in 2020 compared to 2019, considering a reduction of 17.9% on the average price (R$/MWh)) and a decrease in volume (GWh) of electricity sold during the same period.

| · | The revenue from electricity sold to commercial customers decreased by 21.9%, or R$478.3 million, in 2020 compared to 2019, considering a reduction of 7.7% on the average price (R$/MWh) and a decrease in volume (GWh) of electricity sold during the same period.

| · | The revenue from electricity sold to rural customers decreased by 2.9%, or R$18.1 million, in 2020 compared to 2019. This decrease is mainly due to the reduction of consumers compared to 2019 and agribusiness performance in the State of Paraná during the COVID-19 pandemic.

Electricity Sales to Distributors. Our revenues from electricity sales to distributors increased by 31.2%, or R$1,029.7 million. This increase was mainly due to the increase in our revenues from energy sold through bilateral contracts by Copel Mercado Livre and contracts in the regulated environment, reflection of the TPP Araucária dispatch, which had not operated in 2019.

Use of main distribution and transmission grid. Our revenues from the use of main distribution and transmission grid increased by 6.2%, or R$509.6 million, mainly due the positive result of the periodic tariff review of the transmission contract 060/2001, the increase in remuneration on transmission assets, due to the growth of the IGPM / IPCA indexers, the growth in the grid market and the tariff readjustment of Copel Distribuição which corresponded to the Average Tariff effect being 1.13% for consumers connected in high voltage and 0.05% for consumers connected in low voltage. Besides that, there was an increase of 2.6% on the number of consumers compared to 2019.

Construction revenues. Our revenues from construction increased by 24.8%, or R$281.2 million, mainly due an intensification of construction efforts and improvement of the infrastructure of the distribution businesses.

Fair value of assets from the indemnity for the concession. The fair value of the assets from the indemnity for the concession increased by 56.6%, or R$20.7 million, mainly due to higher variation in the distribution concession agreement’s assets fair value.

Distribution of Piped Gas. Revenues from the distribution of piped gas decreased by 32.3%, or R$324.5 million, considering the impacts by the reduction in gas volume due to the Covid-19 pandemic, mainly in the industrial, commercial and vehicular segments.

Sectorial Financial Assets and Liabilities.. Increased by 2,877.4%, or R$721.0 million due to the higher value of net assets constituted in 2020, mainly due to the purchasing energy and charges for use of the network costs being higher than those considered in the calculation of the electricity tariff approved by Aneel for the annual tariff cycle ending in June 2021.

Other Operating Revenues. Other operating revenues decreased by 7.4%, or R$32.4 million, mainly reflecting the recognition of the fair value of the portfolio of energy purchase and sale contracts of Copel Mercado Livre referring to the variation of the contracted price in relation to the market price in an amount lower than that recorded in 2019.

Cost of sales and services provided

Our consolidated costs of sales and services provided increased by 15.0% or R$1,899.8 million. The main factors leading to such increase in our cost of sales and services provided are as follows:

93

| · | Electricity Purchased for Resale. Our purchased energy costs for resale increased by 11.8%, or R$724.2 million, mainly due to an increase in the purchase of Energy in the Regulated Environment – CCEAR of energy from Itaipu Binacional by Copel Distribuição and from bilateral contracts to face the higher volume of energy sold on the free market in the period by Copel Mercado Livre.

| · | Charge of Main Distribution and Transmission Grid. Expenses we incurred for our use of the main distribution and transmission grid increased 22.1%, or R$276.3 million mainly as a result of the increase in tariffs and charges for transmission infrastructure made available from 2020, in addition to the effect of the variation in costs related to dispatching thermal plants, with an impact on system service fees – ESS and increase in charges for the use of the system and in the reserve energy charge - EER, partially offset by the reduction in Itaipu's transportation charges.

| · | Personnel and administrative expenses increased by 20.8%, or R$276.5 million, reflecting the increase in provision for performance and profit sharing and the salary readjustment in October 2020, higher than in 2019, partially offset by the reduction in the number of employees and cost reduction policy.

| · | Material and Supplies for Power Electricity increased 719.6% or R$355.1 million as a result of Araucaria TPP dispatch in 2020.

| · | Natural Gas and Supplies for Gas Business. Expenses related to natural gas purchases decreased 39.4%, or R$230.5 million, mainly due to lower acquisition volume for resale.

| · | Third-Party Services. Expenses related to third party services increased by 6.1%, or R$32.0 million, , mainly due to increase in maintenance of the electrical system in Copel Distribuição, consulting and auditing and customer service.

| · | Depreciation and Amortization. Depreciation and amortization increased by 6.2%, or R$59.2 million, as a result of the start of commercial operations during 2019 of the Colíder, Cutia and Baixo Iguaçu plants. In 2020, all plants depreciated a full year of use compared to prior period.

| · | Accruals and Provisions. Accrual and provisions decreased by 8.8%, or R$22.8 million, mainly due a decrease of R$ 93.6 million in provisions for litigations, partially offset by an increase of R$ 72.6 million referred to generation segment impairment.

| · | Construction Cost. Costs related to construction increased by 29.9%, or R$326.1 million, reflecting the investments made in the transmission, energy distribution and piped gas infrastructure.

| · | Other Costs and Expenses.Other costs and expenses increased 56.8%, or R$120.8 million, mainly due to the repeal of the state law and, consequently, the registration of the water rate reversal in 2019, which is not recurring in 2020.

Equity earnings of associates and joint ventures

Equity earnings of associates and joint ventures was R$193.5 million in 2020, an increase of 81.2%, compared to R$106.8 million in 2019. This variation is a result of an increase by 111.7% in equity earnings of joint ventures, mainly Mata de Santa Genebra, offset by a decrease of 21.4% in equity earnings of associates, mainly Foz do Chopim.

Financial Results

We recognized an increase of financial gains of 290.2%, or R$1,321.7 million mainly due to: (i) increase of R$906.1 million of recognition of tax credit; (ii) increase of R$149.2 million of interest and monetary variation of CRC transfer; (iii) increase of R$ 56.4 million of arrears charges on bills; and, (iv) decrease of R$246.3 of monetary and exchange variation and debt charges.

94

Income Tax and Social Contribution Expenses

In 2020, our income tax and social contribution expenses was R$1,285.4 million, reflecting an effective tax rate of 25.1% in our pretax income, compared to R$675.6 million and an effective tax rate of 23.7% in our pretax profit in 2019.

Net income (loss) from discontinued operations

Due to the ongoing divestment process, as described in Note 40 to our Consolidated Financial Statements, the results of Copel Telecom operations were classified as discontinued operations. The R$183.9 increase in the results of discontinued operations is due to the fact that, in 2019, there was a process of revision of Copel Telecom's property, plant and equipament assets that resulted in significant amounts of impairment and write-offs recorded that year, not recurring in 2020.

Results of Operations for 2019 Compared with 2018

Operating Revenues

Our consolidated operating revenues increased by 9.1% or R$1,318.8 million in 2019 compared to 2018. This result reflected, mainly, an increase of R$1,403.7 million in the use of our main transmission grid, of R$377.7 million in electricity sales to Final Customers; of R$250.6 million in the distribution of piped gas; and of R$165.1 million in electricity sales to distributors, partially offset by a reduction of R$960.3 million in sectorial financial assets and liabilities. Below are the main reasons for variations in revenue accounts.

Electricity Sales to Final Customers. Our revenues from electricity sales to Final Customers increased by 3.7%, or R$377.7 million, mainly due to an increase of 3.96% of total power consumption of our Final Customers mainly in Copel Distribuição, from 25,627 GWh in 2018 to 26,644 GWh in 2019, as follows:

| · | The volume of electricity sold to residential customers increased by 3.6% in 2019 compared to 2018, while there was an increase in the number of customers by 1.9%.

| · | The volume of electricity sold to industrial customers, including both Captive Customers and Free Customers, increased by 3.9% in 2019 compared to 2018, mainly due to the growth of energy consumption of industrial customers in the Free Market, partially offset by the reduction of 1.5% in the number industrial customers in the captive market.

| · | The volume of electricity sold to commercial customers, including both Captive Customers and Free Customers, increased by 5.2% in 2019 compared to 2018. The number of Captive customers increase by 1.6%, in 2019 compared to 2018.

| · | The volume of electricity sold to rural customers increased by 3.2% in 2019 compared to 2018. This increase is mainly due to the performance of agribusiness in the State of Paraná.

Electricity Sales to Distributors. Our revenues from electricity sales to distributors increased by 5.3%, or R$165.1 million, mainly due to the increase in our revenues from electricity sold in regulated contracts, which increased by 121.8%, or R$469.1 million, to R$854.2 million in 2019 compared to R$385.1 million in 2018.

Use of main distribution and transmission grid. Our revenues from the use of main distribution and transmission grid increased by 20.4%, or R$1,403.8 million, mainly due the 3.3% growth in the grid market and the tariff readjustment of Copel Distribuição (with an increase of 16.42% and 11.63% in TUSD as of June 24, 2018 and June 24, 2019, respectively), and the entry into operation of new transmission assets that increased.

Construction revenues. Our revenues construction increased by 3.2%, or R$35.6 million, mainly due to the intensification of construction efforts in 2019 with the objective of improving our distribution and transmission infrastructure.

95

Fair value of assets from the indemnity for the concession. The fair value of the assets from the indemnity for the concession decreased by 22.9%, or R$10.9 million, mainly due to lower variation in the distribution concession agreement’s assets.

Distribution of Piped Gas. Revenues from the distribution of piped gas increased by 33.2%, or R$250.6 million, due to the tariff adjustment and improvement in the gas market.

Sectorial Financial Assets and Liabilities. Sectoral financial assets and liabilities decreased by 97.4%, or R$960.2 million, mainly due to the amortization of the amounts considered in the electricity sales to Final Customers after the Copel Distribuição’s tariff adjustment in June 2018 and the lower variation of balances created for the adjustment applied as of June 2019.

Other Operating Revenues. Other operating revenues increased by 119.7%, or R$239.1 million, mainly due to fair value in the purchases and sale of power revenues, and higher revenues from leases and rents.

Cost of sales and services provided

Our consolidated costs of sales and services provided increased by 1.9% or R$238.5 million. The main factors leading to such increase in our cost of sales and services provided are as follows:

| · | Electricity Purchased for Resale. Our purchased energy costs for resale decreased by 4%, or R$255.9 million, mainly due to a decrease in the cost of "electricity purchased for resale", due to the higher average settlement price (PLD).

| · | Charge of Main Distribution and Transmission Grid. Expenses we incurred for our use of the main distribution and transmission grid increased 6.2%, or R$72.5 million, mainly as a result of the increase in tariffs and charges for transmission infrastructure made available for new generation projects from 2019, in addition to the effect of the variation in costs related to dispatching thermal plants, with an impact on system service fees - ESS.

| · | Personnel and Management. Expenses decreased by 2.4%, or R$32.4 million, mainly due the decrease in costs reflects on employee reduction occurred in 2019, despite the increase in the provision for profit sharing (PLR) due to the improvement in our results.

| · | Material and Supplies for Power Electricity. These expenses increased 150.1% or R$29.7 million, mainly as a result of the completion of Araucária TPP in 2019.

| · | Natural Gas and Supplies for Gas Business. Expenses related to natural gas purchases increased 41.8%, or R$172.6 million, mainly due to growth in the market of Compagas and exchange variation.

| · | Third-Party Services. Expenses increased by 9.3%, or R$44.9 million due to the variation of maintenance value of the electric system, communication, data processing and transmission and advisory and auditing services.

| · | Depreciation and Amortization. Increased by 36.5%, or R$254.4 million, mainly due the costs with depreciation and amortization resulting from the start of commercial operation in 2019 at the Colíder, Cutia and Baixo Iguaçu plants.

| · | Accruals and Provisions. Decreased by 7.5%, or R$21.1 million, mainly due to a reversal of generation segment impairment, partially offset by an increase in expected credit losses.

| · | Construction Cost. Increased by 3.7%, or R$39.2 million, mainly reflecting investments in transmission, distribution and Compagas assets.

| · | Other Costs and Expenses. Decreased 22.1%, or R$60.1 million, mainly due to lower losses in the decommissioning and disposal of assets in Copel Distribuição.

96

Equity earnings of associates and joint ventures

Equity earnings of associates and joint ventures was R$106.8 million in 2019, a decrease of 21.4%, compared to R$135.9 million in 2018, mainly due to a decrease in the profits of our associate entities and joint ventures.

Financial Results

We recognized an increase of financial losses of 10.2%, or R$42.2 million, mainly due a decrease by 8.5% in financial revenues (monetary variation on CRC onlendings, recognition of tax credits and other financial income).

Income Tax and Social Contribution Expenses

In 2019, our income tax and social contribution expenses was R$675.6 million, reflecting an effective tax rate of 23.7% in our pretax income, compared to R$471.2 million and an effective tax rate of 525.6% in our pretax profit in 2018.

Net income (loss) from discontinued operations

Due to the ongoing divestment process, as described in Note 40 to our Consolidated Financial Statements, the results of Copel Telecom operations were classified as discontinued operations. The R$185.5 decrease in the results of discontinued operations is due, mainly, to the process of revision of Copel Telecom's property, plant and equipament assets that resulted in significant amounts of impairment and write-offs recorded in 2019

97

LIQUIDITY AND CAPITAL RESOURCES

Our principal liquidity and capital requirements are to finance the expansion and improvement of our distribution and transmission infrastructure and to finance the expansion of our generation facilities.

We believe our working capital is sufficient for our present requirements and the next 12 months. We expect to finance our liquidity and capital requirements primarily with own resources, arising from retained earnings and cash generation from our operations and third party resources (BNDES, Other Financial Institutions and Capital Markets). However, the expectation of the economic impacts resulting from the shutdown caused by the outbreak of the coronavirus (COVID-19), with subsequent effects on Copel's operations, may affect Company's financial results. In December 2020, our Current Liquidity, an index ratio that measures our current assets over our current liabilities reached 1.2x (1.5x in 2019) with a cash balance, equivalent to cash and marketable securities of R$ 3,545.9 million (R$3,223.8 million in 2019 and R$ 2,292.7 million in 2018).

With respect to long term capital needs, we use a model of five years to monitor our needs in a series of scenarios and variables, including Net Debt/ EBITDA and minimum cash balance with the intention to preserve the liquidity and improve the capital structure. In this context, we work to anticipate exercises of liability management to improve liquidity or if conditions are favorable.5

All of our future liquidity conditions rely on a series of scenarios and may be adversely affected depending on market and other conditions. Actual liquidity may differ significantly for several reasons, including, without limitation, the risks described in “Forward-Looking Statements” and “Item 3. Key Information―Risk Factors”.

We have not engaged in any off-balance sheet arrangements that have, or are reasonably likely to have a current or future effect on the registrant’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.7F

We monitors our financial liquidity continuously and, for that that purpose, we consider (i) on the external side, the possibility of raising funds and the prospect of preserving cash through the assistance of structural measures by the Brazilian government and other Sectoral Institutions, and (b) on the internal side, taking the necessary actions in our operations by reducing expenses or postponing investments in order to guarantee the timely fulfillment of financial obligations. Accordingly, we expect to preserve the working capital required for our operations throughout the period.

In addition to working capital, our other principal uses of cash are capital expenditures, dividend payments and debt servicing. Capital expenditures were R$1,904.7 million in 2020 and R$2,055.6 million in 2019. The following table sets forth a breakdown of our capital expenditures for the periods indicated. Our capital expenditures are focused on projects located in Brazil.

As in previous years, our capital requirement will be financed by cash from our operations and/or by external financing, which may serve to offset commitments arising from the maturity of previous external financing.

Our total budgeted capital expenditures for our wholly-owned subsidiaries for 2021 is R$1,902.7 million, of which:

| · | R$320.0 million are for generation and transmission;

| · | R$1,217.6 million are for our distribution business;

| · | R$50.0 million are for our telecommunication business;

| · | R$292.2 million for the construction of the Cutia Wind Farm Complex and Jandaíra Wind Farm Complex; and

| · | R$22.9 million are for other investments.

Our following subsidiaries also budgeted their own capital expenditures for 2021, as described as follows:

| · | Compagas: R$18.8 million;

| · | Araucária: R$1.2 million; and

| · | Elejor: R$18.3 million.

Historically, we have financed our liquidity and capital requirements primarily with cash provided by our operations and through external financing. Our principal source of funds in 2020 was our operating activities. Net cash used by financing activities was R$1,791.5 million in 2020, compared with R$288.0 million in 2019. . Net cash provided by operating activities was R$3,940.8 million in 2020, compared with R$2,945.0 million in 2019 and R$1,771.0 in 2018. The increase is mainly explained by the fully operation of new power plants, as HPP Colider and Cutia Wind Farm, which started up their operation during 2019, the adjustments in transmission and distribution tariffs, the start up of new transmission assets and cost savings measures. In 2020, we also received the proceeds from the Covid Account in the Distribution Company. In 2021, we expect to finance our liquidity and capital requirements primarily with own Resources, arising from retained earnings and cash generation from our operations and Third Party Resources (BNDES, Other Financial Institutions and Capital Markets).

Long-term debt have generally been used to finance our major capital expenditure projects, or capital expenditures acquisition financing programs offered by Federal Development Bank, as BNDES. The scheduled maturities of these long-term loans have been structured to match the expected cash flow from the conclusion of the related capital expenditure projects and, as a result, reduce the risk of any significant deterioration of our liquidity position.

As in prior years, we plan to make significant investments in future periods to expand and upgrade our generation, transmission and distribution businesses. In addition, we may seek to invest in other existing electric utilities, in communications services or in other areas, each of which may require additional domestic and international financing. Our ability to generate cash sufficient to meet our planned expenditures is dependent upon a variety of factors, including our ability to maintain adequate tariff levels, to obtain the required regulatory and environmental authorizations, to access domestic and international capital markets, and a variety of operating and other contingencies. We anticipate that our cash provided by operations may be insufficient to meet these planned capital expenditures, and that we may require additional financing from sources such as BNDES and the Brazilian and international capital markets.

ANEEL’s regulations require prior approval from ANEEL for any transfer of funds from our subsidiaries to us in the form of loans or advances. ANEEL approval is not required for cash dividends, as long as cash dividends do not exceed a dividend threshold (“Dividend Threshold”) equal to the greater of adjusted net income or income reserves available for distribution. The Dividend Threshold is established by Brazilian Corporate Law.

99

The cash dividends we have received from our subsidiaries have been historically sufficient to meet our cash flow requirements without exceeding the Dividend Threshold. As a result, we have not sought approval from ANEEL to receive either loans or advances from our subsidiaries or cash dividends from our subsidiaries in excess of the Dividend Threshold. We do not expect these restrictions on loans and advances and on cash dividends exceeding the Dividend Threshold to impact our ability to meet our cash obligations, since we expect cash dividends below the Dividend Threshold to be sufficient in the future.

Like other state-owned companies, we are subject to certain CMN restrictions on our ability to obtain financing from domestic and international financial institutions. CMN restrictions could limit our ability to obtain bank financing but do not affect our ability to access the Brazilian and international capital markets, and do not restrict our access to banking financing for the purpose of repaying or refinancing debt.

Our total outstanding loans and financing (including debentures) as of December 31, 2020 totaled R$9,946.0 million. Approximately R$140.3 million of the total debt outstanding as of December 31, 2020 was denominated in U.S. dollars. For more information on the terms of these loans and financingsincluding reference to their specific maturity dates and interest rate structure, see Notes 21 and 22 to our audited consolidated financial statements. We are not subject to seasonality with respect to our borrowing requirements. Our major loans and financing arrangements are:

Item 6. Directors, Senior Management and Employees

We are managed by:

| · | a Board of Directors, which may be composed of up to nine (9) members and is currently composed of nine (9) members; and

| · | a Board of Executive Officers, which is currently composed of seven (7) members.

BOARD OF DIRECTORS

The Board of Directors ordinarily meets monthly. A majority of the members of the Board of Directors is required for the meeting to be held, and decisions are taken by a majority vote of those present at the meeting. For additional information, see “Item 10. Additional Information—Memorandum and Articles of Association”. The members of the Board of Directors are elected to serve for two-year terms and may be reelected up to another three consecutive terms. Among the current nine members of the Board of Directors:

| · | six were elected by the controlling shareholders;

| · | one was elected by minority shareholders (holding voting shares);

| · | one was elected by minority shareholders (holding outstanding non-voting shares); and

| · | one was elected by our employees.

According to Brazilian Corporate Law, minority shareholders are entitled to appoint and remove at least one member of the Board of Directors, in a separate election, without the participation of the controlling shareholder, if such minority shareholders hold (i) at least 15% of our voting shares or (ii) at least 10% of the company’s outstanding non-voting shares. Minority shareholders holding at least 10% of our voting shares are entitled to request that a multiple voting procedure be adopted, a proceeding that grants each voting share as many votes as there are members of the Board of Directors and the right for all the voting shareholders to vote for only one candidate or to distribute his votes among several candidates, also in accordance with the Brazilian Corporate Law.

Our bylaws entitle minority shareholders that hold voting shares the right to appoint and remove two members of the Board of Directors, in a separate election, regardless of the voting shares which are held by them as a class, if they haven’t appointed a higher number through a Multiple Vote proceeding in the general shareholders’ meeting. Moreover, our employees are also entitled to appoint and remove one member of the Board of Directors. However, if a multiple vote proceeding is adopted and, also, the minority shareholders appoint members of the Board of Directors through a separate election, the controlling shareholder is entitled to appoint and remove the same number of members appointed and elected by the minority shareholders and employees.

Also according to Brazilian Corporate law, members of our Board of Directors who are elected by the non-controlling shareholders have the right to veto (provided it is duly justified) the appointment of the independent accountant made by the majority of the members of our Board of Directors.

The terms of the current members of the Board of Directors expire in April 29th, 2021. The current members of our Board of Directors are:

On December 31, 2020, we had 6,667 employees, compared to 7,095 employees on December 31, 2019 and 7,611 employees on December 31, 2018. Including employees at Compagas, Elejor and UEG Araucária Ltda. (companies in which we have a majority stake) we had 6,832 employees as of December 31, 2020.

The following table sets forth the number of our employees and a breakdown of employees by area of activity as of the dates indicated in each area of our operations.

| As of December 31,
Area | 2020 | 2019 | 2018

Total | 6,832 | 7,266 | 7,794

All of our employees are covered by collective bargaining agreements that we renegotiate annually with the unions that represent the various employee groups. In 2020, we negotiated and signed labor agreements with the unions representing our employees. These new bargaining agreements became effective in October and will be in place for a period of two years. We agreed to salary increases of 3.89% in 2020 compared to 2019 salaries.

We provide a number of benefits to our employees. The most significant is our sponsorship of Fundação Copel de Previdência e Assistência Social (“Fundação Copel”), which supplements the Brazilian government retirement and health benefits available to our employees. As of December 31, 2020, approximately 99% of our employees had elected to participate in a defined contribution plan.

In accordance with federal law and our compensation policy, our employees participate in a profit-sharing plan. The Board of Directors and the shareholders must approve the amount of such compensation, which is determined in accordance with an agreement between an employee committee and us. An employee’s receipt of compensation is conditioned on the company meeting certain benchmarks described in the above-mentioned agreement, as confirmed in our published year-end financial statements. The amount of profit-sharing distributions reserved and approved for the 2020 fiscal year (including Compagas) was R$ 416.9 million. The amount of profit-sharing distributions accrued and approved for the 2019 fiscal year (including Compagas) was R$155.5 million. The terms of the profit-sharing agreement are currently being revised and negotiated for future years.

In 2020, we had two Voluntary Redundancy Programs (“PDI” in Portuguese). The first was launched on October 1, 2020 in two stages:

| · | Phase 1: Eigibility for employees in the technical and operational departments as long as they have a retirement benefit granted or a benefit request filed with the INSS, or have been employed by Copel for at least 25 years and are 55 years old. The accessions for this phase occurred between October 1 and October 15, 2020, and the dismissals of employees who adhered to the PDI in this Phase 1 ocurred on November 15, 2020; and

| · | Phase 2: Eligibility for employees in the other areas, positions and functions, provided that they have a retirement benefit granted or a benefit request filed with the INSS or have been employed by Copel for at least 25 years and are 55 years old. The accessions for this phase occurred between November 1 and November 15, 2020, and the dismissals of employees who adhered to the PDI in this Phase 2 ocurred on December 1, 2020.

114

Under the entire program, 311 terminations occurred in 2020 for a total of R$35.4 million in severance payments.

The second program was aimed at employees assigned to Copel Distribuição's Call Center, who work in the functions of Call Center Monitor, Call Center Support Monitor and call center.

Of the 375 eligible employees, 169 employees adhered to the PDI, which represents an estimated cost of R$25.3 million with severance pay and a potential reduction of R$9 million in annual costs as of 2022, since the dismissals must occur between July 15, 2021 and September 15, 2021, according to program rules.

With the completion of this program and considering the results of the penultimate PDI, concluded on December 1, 2020 with the termination of 311 employees, the Company ends 2020 with the adhesion of 480 employees to the incentive dismissal programs, equivalent to a reduction of 6.9% in the staff of September 2020 (7,006 employees). The indemnities are estimated at R$61.9 million, while the potential cost reduction is estimated at R$68.1 million from 2021, an amount that rises to R$77.1 million from 2022, when the effects of the Call Center PDI are now perceived.Additionally, the PDI balance recognized in 2020 is R$66,9 million (according to NE 32.2).

On February 12, 2020 the Board of Directors approved the implementation, within Copel and its wholly-owned subsidiaries, of a short-term incentive program called Performance Incentive Program, or Prêmio Por Desempenho (“PPD”) directed at aligning efforts throughout different organizational levels to the company's strategic objectives.

The program prizes technical consistency and takes the best market practices into account. It was developed with the support of Fundação Instituto de Administração – FIA, a consultancy that specializes in people management modernization projects for the private sector as well as state-owned companies.

As a result, Copel improves its target-based management strategy and enhances its merit-based culture, thus aligning with the achievement of its strategic plan. Upholding the company's values, the implementation of the program reflects the commitment of Copel's management to the improvement of the group's operational efficiency, and to the highest corporate governance standards, strengthening the pillars that support the business' sustainable growth and longevity.

Legal Proceedings

We are currently subject to numerous proceedings relating to civil, administrative, labor and tax claims. Our audited consolidated financial statements only include provisions when the Company has a present obligation (legal or constructive) resulting from a past event; it is probable (i.e. more likely than not) that an outflow of resources embodying economic benefits will be required to settle the obligation; and a reliable estimate can be made of the amount necessary to settle the obligation. As of December 31, 2020, our provisions for such risks were R$ 1,555.7 million. However, it is possible that some amounts actually paid are different from the estimates made in recognizing these provisions because of determinations of final judgments and/or liquidations of the award.

As of December 31, 2020, we estimate that the total amount of claims against us, excluding disputes involving non-monetary claims or claims whose potential losses cannot be reasonably estimated due to the current early stages of proceedings, for which no provisions have been made, was approximately R$ 5,206.8 million, of which R$ 345.1 million correspond to labor claims; R$ 9.2 million to employee benefits; R$ 1,159.0 million to regulatory claims; R$ 3,116.9 million to civil claims; and R$ 576.6 million to tax claims. For more information, see Note 29 to our audited consolidated financial statements.

Tax and Social Contribution Claims

During the second half of 2010, two lawsuits were decided before the Federal Regional Court (Tribunal Regional Federal) in favor of the Brazilian government, reversing the prior judgment that recognized our immunity regarding the payment of COFINS tax. As a result, the Federal Internal Revenue Service (Receita Federal) issued an infraction notice demanding the payment of COFINS tax from the period between August 1995 and December 1996. As of December 31, 2020, we had provisioned R$ 107.1 million to cover expected losses related to these lawsuits.

Additionally, we are party to administrative and judicial proceedings pursuant to which we are challenging claims of the Brazilian Social Security authorities to pay additional security contributions for the period between 2000 and 2006. In these proceedings, we estimate the amount of our expected loss to be R$ 29.4 million.

Labor-related Claims

We are the defendant in several lawsuits filed by either current or past employees of ours, related to overtime claims, dangerous work conditions, relocation, and other matters. As of December 31, 2020, we have provisions totaling R$ 596.2 million reflecting the expected losses related to these lawsuits.

Regulatory

We are disputing certain regulatory and legal proceedings in connection with ANEEL’s allegations that we violated regulatory standards. As of December 31, 2020, we have provisions totaling R$ 88.7 million reflecting the expected losses related to these proceedings.

Additional Claims

We are party to several lawsuits related to accidents involving equipment used in our electricity transmission and distribution grids and vehicle accidents (see Note 29.1 to our audited consolidated financial statements). As of December 31, 2020, we have provisions totaling R$387.9 million reflecting the expected losses related to these lawsuits.

We are also party to several lawsuits brought by landowners whose land has been affected by our transmission and distributions lines. As of December 31, 2020, we have provisions totaling R$245.4 million reflecting the expected losses related to these lawsuits.

Dividend Payment

In accordance with our bylaws and Brazilian Corporate Law, we regularly pay annual dividends for each fiscal year within sixty days of the declaration of the dividends at the annual shareholders’ meeting or by the Board of Directors. To the extent amounts are available for distribution, we are required to distribute as a mandatory dividend an aggregate amount equal to at least 25.0% of our adjusted net profit. Dividends are allocated pursuant to the formula described in “Dividend Priority of Class A Shares and Class B Shares” below. Under Brazilian Corporate Law, we are not permitted to suspend the mandatory dividend payable with respect to the Common Shares, Class A Shares and Class B Shares for any year. Brazilian Corporate Law permits, however, a company to suspend the payment of all dividends if the Board of Directors, with the approval of the Supervisory Board, reports at the shareholders’ meeting that the distribution would be detrimental to the Company given its financial circumstances. In such a case, companies with publicly traded securities must submit a report to the CVM providing the reasons for the suspension of dividend payments. Notwithstanding the above, Brazilian Corporate Law and our bylaws provide that Class A Shares and Class B Shares shall acquire voting rights if we suspend the mandatory dividend payments for more than three consecutive fiscal years, and such voting rights will continue until all dividend payments, including back payments, have been made. We are not subject to any contractual limitations on our ability to pay dividends.

In accordance with our dividends policy, we may distribute yearly regular dividends higher than the mandatory minimum of 25% following certain guidelines related to our Financial Leverage Ratio, defined as the ratio between net debt and interest, taxes, depreciation, and amortization:

| · | If our Financial Leverage Ratio is below 1.5x, we shall distribute 65% of our adjusted net profits.

| · | If our Financial Leverage Ratio is in between 1.5x and 2.7x, we shall distribute 50% of our adjusted net profits.

| · | If our Financial Leverage Ratio is higher than 2.7x, we shall distribute the mandatory minimum of 25% of our adjusted net profits.

Any distribution of dividends higher than the minimum amount of 25% of our adjusted net profits is constrained to the Available Cash Flow of the same year, defined as the operating cash flow minus net cash flow used for investment.

Calculation of Adjusted Net Profit

Annual dividends are payable from our adjusted net profit for such period. Brazilian Corporate Law defines “net profit” for any fiscal year as the result of a fiscal year after the deduction of income and social contribution taxes for that fiscal year and after the deduction of any amounts allocated to employees’ and management’s participation in our results in such fiscal year. The “net profit” for a relevant fiscal year is subject to adjustment by the addition or subtraction of amounts allocated to legal and other reserves, the result of which is known as our adjusted net profit.

In accordance with Brazilian Corporate Law, we must maintain a legal reserve, to which we must allocate a minimum of 5% of our net profits for each fiscal year until such reserve reaches an amount equal to 20.0% of our capital stock (calculated in accordance with Brazilian Corporate Law). However, we are not required to make any allocations to our legal reserve in a fiscal year in which the legal reserve, when added to our other established capital reserves, exceeds 30.0% of our total capital stock. The amounts to be allocated to such reserve must be approved by our shareholders in a shareholders’ meeting and may be used only for the increase of our capital stock or compensation of losses.

On December 31, 2020, our legal reserve was R$1,209.5 million, or approximately 11.2% of our capital stock at that date.

In addition to deducting amounts for the legal reserve, under Brazilian Corporate Law net profit may also be adjusted by deducting amounts allocated to:

| · | the contingency reserve: under Brazilian Corporate Law, our shareholders’ meeting, upon a justified proposal of our Board of Directors or Board of Executive Officers, may decide to allocate a percentage of our net profits to a contingency reserve for anticipated losses that are deemed probable in future years, which amount may be estimated;

121

| · | the tax incentives reserve: under Brazilian Corporate Law, our shareholders’ meeting, upon a justified proposal of our Board of Directors or Board of Executive Officers, may decide to allocate a percentage of our net profits resulting from government donations or subsidies for investment purposes.

On the other hand, net profits may also be increased by:

| · | the reversal of any amounts previously allocated to a contingency reserve in the fiscal year in which the loss that had been anticipated does not occur as projected or in which the anticipated loss occurs but is lower than the contingency allocated to it; and

| · | any amounts included in the unrealized profits reserve that have been realized in the relevant fiscal year and have not been used to offset losses, as approved by our shareholders’ meeting, upon the proposal of our Board of Directors or Board of Executive Officers.

Moreover, our net profits are also adjusted by adding the realization of amounts registered under “Equity Value Adjustments”. The account “Equity Value Adjustments” was created as a result of the first-time adoption of IFRS by Copel in 2010, which caused a fair value revaluation of certain fixed assets and the adoption of the fair value as its “deemed cost” at that date. The increase of the deemed cost of fixed assets led to an increase in depreciation costs. Thus, our management has decided to add to the adjusted net profits the realization of the “Equity Value Adjustments” in order to compensate for effects of the increased depreciation costs. In 2020, our adjusted net profits used to calculate our dividends was increased by R$59.6 million as a result of said realization.

The amounts available for distribution are determined on the basis of the Statutory Financial Statements prepared using the method required by Brazilian Corporate Law, which differ from our audited consolidated financial statements included herein.

Dividend Priority of Class A Shares and Class B Shares

According to our bylaws, Class A Shares and Class B Shares are entitled to receive annual, non-cumulative minimum dividends, which dividend per share shall be at least 10% higher than the dividends per share paid to the holders of the Common Shares. Class A Shares have a dividend priority over the Class B Shares, and Class B Shares have a dividend priority over the Common Shares. To the extent that dividends are paid, they are to be paid in the following order:

| · | first, the holders of Class A Shares have the right to receive a minimum dividend equal to 10% of the total share capital represented by the Class A Shares outstanding at the end of the fiscal year in respect of which the dividends have been declared;

| · | second, to the extent there are additional amounts to be distributed after all amounts allocated to the Class A Shares have been paid in accordance with the first bullet point above, the holders of Class B Shares have the right to receive a minimum dividend per share equal to (i) the mandatory dividend divided by (ii) the total number of Class B Shares outstanding at the end of the fiscal year in respect of which the dividends have been declared; and

| · | third, to the extent that there are additional amounts to be distributed after all amounts allocated to the Class A Shares and the Class B Shares have been paid, the holders of Common Shares have the right to receive an amount per share equal to (i) the mandatory dividend divided by (ii) the total number of Common Shares outstanding at the end of the fiscal year in respect of which dividends have been declared, provided that the Class A Shares and Class B Shares receive dividends per share at least 10% higher than the dividends per share paid to the Common Shares.

122

To the extent that there are additional amounts to be distributed after all amounts described in the preceding items have been paid and in the form therein described, any such additional amount will be divided equally among all our shareholders.

Payment of Dividends

We are required to hold an annual shareholders’ meeting by April 30th of each year at which, among other things, an annual dividend may be declared by decision of the shareholders on the recommendation of the management, as approved by the Board of Directors. The payment of annual dividends is based on the financial statements prepared for the fiscal year ending December 31. Under Brazilian Corporate Law, we must pay dividends to shareholders of record within 60 days of the date of the shareholders meeting that declared the dividends. A shareholders’ resolution may set forth another date of payment, which must occur prior to the end of the fiscal year in which such dividend was declared. We are not required to adjust the amount of paid-in capital for inflation for the period from the end of the last fiscal year to the date of declaration or to adjust the amount of the dividend for inflation for the period from the end of the relevant fiscal year to the payment date. Consequently, the amount of dividends paid to holders of Class B Shares may be substantially reduced due to inflation.

Pursuant to our bylaws, our management may declare interim dividends to be paid from profits in our semi-annual financial statements, in accordance with the Company's dividend policy and subject to further endorsement by the Shareholders’ Meeting. Any payment of interim dividends counts towards the mandatory dividend for the year in which the interim dividends were paid. In accordance with our dividends policy, our management should approve interim dividends and annual dividends every year.

Pursuant to Brazilian Corporate Law, we may pay interest on equity in lieu of dividends as an alternative form of making distributions to shareholders. We may treat a payment of interest on equity as a deductible expense for tax purposes, provided that it does not exceed the lesser of:

| · | the total amount resulting from (i) Long-Term Interest Rate (Taxa de Juros a Longo Prazo, or “TJLP”) multiplied by (ii) the total shareholders’ equity (determined in accordance with Brazilian tax legislation), less certain deductions prescribed by Brazilian tax legislation; and

| · | the greater of (i) 50.0% of current net income (after the deduction of social contribution on profits (CSLL ‒ Contribuição Social sobre o Lucro Líquido) and before taking such distributions and any deductions for corporate income tax) for the year in respect of which the payment is made or (ii) 50.0% of retained earnings and profit reserves for the year prior to the year in respect of which the payment is made.

In order to be eligible to receive amounts remitted in foreign currency outside of Brazil, shareholders who are not residents of Brazil must register with the Brazilian Central Bank in order to receive dividends, sales proceeds or other amounts with respect to their shares. The Class B Shares underlying the ADSs are held in Brazil by the Custodian, as agent for the Depositary, which is the registered owner of our shares.

Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the Custodian on behalf of the Depositary, which will then convert such proceeds into U.S. dollars and will cause such U.S. dollars to be delivered to the Depositary for distribution to holders of ADSs. In the event that the Custodian is unable to immediately convert the Brazilian currency received as dividends into U.S. dollars, the amount of U.S. dollars payable to holders of ADSs may be adversely affected by devaluations of the Brazilian currency that occur before such dividends are converted and remitted. In the event the holder of an ADS fails to collect its dividends from the Custodian within three (3) years, counted as of the date when such dividend was made available, Brazilian corporate law states that such dividends may be returned to us. In this case, the ADS holder shall lose its right to receive the dividends.

A director or an executive officer may not transact any business with a company, including accepting any loans, except on reasonable and fair terms for the Company and conditions that are identical to the terms and conditions prevailing in the market or offered by third parties. According to our bylaws, shareholders set the aggregate compensation payable to directors, executive officers, and members of the Supervisory Board. For more information, see “Item 6. Directors, Senior Management and Employees”. Our bylaws do not establish any mandatory retirement age limits.

125

Board of Directors and Board of Executive Officers

For further information, see Items 6 – “Directors, Senior Management and Employees - Board of Directors” and “Directors, Senior Management and Employees - Board of Executive Officers”.

Shareholders’ Meetings

The convening of our shareholders’ meeting is made through publication of a notice to shareholders in two newspapers, which are determined at the previous shareholders’ meeting. Generally, we make such notice in Diário Oficial do Estado – PR and the Folha de Londrina. As provided by Brazilian Corporate Law, publications have to be made in the official newspaper located in the state of our corporate headquarters, and in a newspaper with wide circulation in the same city as our corporate headquarters. The notice must be published no fewer than three times, beginning at least 30 calendar days prior to the scheduled meeting date.

In order for a shareholders’ meeting to be held on first call, shareholders representing at least one- quarter of the voting capital have to be present, except as otherwise provided for under Brazilian law. If no such quorum is verified, a second meeting may be called by notice given at least 8 calendar days prior to such meeting and in accordance with the same rules of publication previously described. The quorum requirements will not apply to a second meeting, subject to the minimum quorum and voting requirements for certain matters, as discussed as follows. A shareholder without a right to vote may attend a general shareholders’ meeting and take part in the discussion of matters submitted for consideration.

A shareholder may be represented at a general shareholders' meeting by a proxy appointed in accordance with applicable Brazilian law not more than one year before the meeting, who must be a shareholder, a company officer, a lawyer or a financial institution.

126

Right of Withdrawal

Our common shares and preferred shares are not redeemable, with the exception that a dissenting shareholder has, under certain circumstances provided for in Brazilian Corporate Law, the right to withdraw its equity interest from a company and to receive a payment for the portion of shareholder’s equity attributable to his or her equity interest.

Preferred Shares Rights

Pursuant to Brazilian Corporate Law, each preferred share of a class that is admitted to trading on a Brazilian stock exchange must have the certain rights under the Company’s bylaws.

Our bylaws comply with the directives provided by Brazilian Corporate Law as follows: (i) our Class A Shares shall have priority in the distribution of minimum dividends of 10% per year, pro rata, calculated as a percentage of the paid-in capital stock represented by such shares on December 31 of the previous fiscal year; (ii) our Class B Shares shall have priority in the distribution of minimum dividends, pro rata, in the amount equivalent to 25.0% of our net profits, as adjusted in accordance with Section 202 of Law No. 6,404/76, calculated as a proportion of the paid-in capital stock represented by such shares on December 31st of the previous fiscal year; (iii) the dividends paid on Class B Shares pursuant to item (ii) above shall be paid only from any remaining profits after the payment of priority dividends to Class A Shares; and (iv) the dividends to be paid per preferred share, regardless of the class, shall be at least 10% higher than the dividends to be paid per Common Share; and (v) the preferred shares will acquire voting rights if, during three consecutive fiscal years, we fail to pay a fixed or minimum dividend to which the preferred shares are entitled. For more information on our dividend policy, see “Item 8. Financial Information – Dividend Payment.”

Voting Rights

As a general rule, only our Common Shares are entitled to vote and each Common Share corresponds to one vote. Holders of preferred shares acquire voting rights if, during three consecutive fiscal years, we fail to pay a fixed or minimum dividend to which the preferred shares are entitled. If a holder of preferred shares acquires voting rights in this manner, such rights will be identical to the voting rights of a holder of Common Shares and will continue until the dividend is paid.

Furthermore, in accordance with our bylaws holders of preferred shares are entitled to voting rights in regards of specific matter discussed in a shareholders’ meeting:

| · | Change in Copel’s corporate type into another, as well as incorporation, merger or spin-off.

| · | Agreements between Copel and its controlling shareholder, directly or through a third party, or an entity influenced by the controlling shareholder, when such agreements shall be discussed in a shareholders’ meeting by force of statute or our bylaws.

| · | Appraisal of assets for paying in Copel’s capital increase.

| · | Choice of an entity to be hired for the assessment of the economic value of Copel.

| · | Change or revocation of articles in our bylaws that alter or modify any of the requirements set forth in item 4.1. of the regulation of the Level 2 of B3, while the Level 2 participation contract is still in effect.

Exclusion or change in our bylaws aimed to suppress the right set forth in article 28, XXIX of our bylaws, which provides for the adoption of the full tariff set by a granting authority, requires the approval of most of the preferred shares.

Preemptive Rights

Our shareholders have a general preemptive right to subscribe for shares in any capital increase, in proportion to his or her ownership, as provided for in the Brazilian Corporate Law. A minimum period of 30 days following the publication of notice of a capital increase is assured for the exercise of the right, and the right is transferable. We may issue shares up to the limit of the authorized capital, excluding right of first refusal to the shareholders, as provided for in the Brazilian Corporate Law and in our bylaws.

127

Liquidation

In the event of liquidation of the Company, after all creditors have been paid, all shareholders will participate equally and ratably in any remaining residual assets.

Liability of the Shareholders for Further Capital Calls

Neither Brazilian Corporate Law nor our bylaws provide for capital calls. The shareholders’ liability is limited to the payment of the issue price of the shares subscribed or acquired.

Conversion Rights

Our bylaws provide, as a general rule, that the only permitted conversion of shares is Class A Shares are convertible into Class B Shares. As an exception, Class B Shares can be converted into Common Shares, and vice-versa, strictly for the formation of Units made of four Class B Shares and one Common Share under Copel’s unitization programs set by the Board of Directors. Our shares are not otherwise convertible.

Form and Transfer

Our shares are maintained in book-entry form with a transfer agent (“Transfer Agent”). To make a transfer of shares, the Transfer Agent makes an entry in the register, debits the share account of the transferor and credits the share account of the transferee.

Transfers of shares by foreign investors are made in the manner described above and are executed by the investor’s local agent on the investor’s behalf. However, if the original investment was registered with the Brazilian Central Bank pursuant to a foreign investment mechanism regulated by Resolution No. 4,373 of September 29, 2014 of the CMN (“Resolution No. 4,373”) as described under “Exchange Controls” as follows, the foreign investor must declare the transfer in its electronic registration.

A shareholder may choose, in its individual discretion, to hold its shares through B3. Shares are added to the B3 system through Brazilian institutions that have clearing accounts with the B3. Our shareholder registry indicates which shares are listed on the B3 system. Each participating shareholder is in turn registered in a register of beneficial shareholders maintained by the B3 and is treated in the same manner as the other registered shareholders.

Changes in Rights of Shareholders

A General Meeting of Shareholders must be held whenever the Company intends to change the rights of holders of our common shares or preferred shares. Under Brazilian Corporate Law the proposed changes must be approved by a majority of the class of shareholders that would be affected. Certain changes related to the rights of preferred shares, such as changes in preferences, advantages or conditions of redemption or amortization, may result in the exercise of rights to withdraw by the holders of the shares affected.

Regulation of and Restrictions on Foreign Investors

Foreign investors face no legal restrictions barring them from holding Common Shares, Class A Shares, Class B Shares or ADSs.

The ability to convert into foreign currency dividend payments and proceeds from the sale of Class B Shares or preemptive rights, and to remit such amounts outside Brazil is subject to restrictions under foreign investment legislation which generally requires, among other things, the registration of the relevant investment with the Brazilian Central Bank. Any foreign investor who registers with the CVM in accordance with CMN Resolution No. 4,373 may buy and sell securities on Brazilian stock exchanges without obtaining a separate certificate of registration for each transaction.

Annex II to CMN Resolution No. 4,373 (“Annex II Regulations”) allows Brazilian companies to issue depositary receipts in foreign exchange markets. Our ADS program is duly registered with the Brazilian Central Bank and the CVM.

Our bylaws do not impose any limitation on the rights of Brazilian residents or non-residents to hold our shares and exercise the rights in connection therewith.

Disclosure of Shareholder Ownership

Under Brazilian regulations any person or group of persons representing the same interest that carries out a relevant trading involving shares or securities issued by a publicly traded company must disclose its share ownership to the investor relations officer of such company, which, in turn, must disclose such information to the CVM and to any relevant stock exchange. A relevant trading is defined as a transaction by which the direct or indirect equity stake of the persons referred above reaches an equity interest corresponding to 5% or its multiples (10%, 15%, and so on), of a type or class of shares representing the company’s capital stock. Any subsequent increase or decrease of 5% or its multiples in ownership of any class of shares must be similarly disclosed. The same reporting obligation applies to the acquisition of any rights over the shares and other securities mentioned in applicable regulation and to the execution of any derivative financial instruments referenced in shares. If such increase results in change of corporate control or administrative structure, or if the increase imposes a public offering, in addition to informing the investor relations officer, a statement containing certain required information must be published in newspapers that are widely circulated in Brazil.

Change of Controlling Shareholder

Under the Brazilian constitution and our bylaws, a change of the controlling shareholder, the State of Paraná, is only permitted with legislative authorization. If such approval is granted to the State of Paraná, and the change in the control over us would happen by a private sale of shares held by the current controlling shareholder or sale of preemptive rights from such controlling shareholder, such transaction shall be subject to the buyer launch a tender offer for the shares held by the minority shareholders.

Arbitration

As provided for in our bylaws, we, our shareholders, directors, officers and members of the supervisory board shall resolve through arbitration any dispute or conflict that may arise between them, regarding, among others, the application, validity, effectiveness, interpretation, violation and corresponding effects of the provisions of our bylaws, of the current applicable law, of the rules applicable to the capital markets in general, as well as those of the regulation of the level 1 of corporate governance of B3 (Brasil, Bolsa, Balcão) (“Level 1”), of the Level 1 participation contract, and of the Sanctions and the Arbitration Regulations of the B3 Market Arbitration Chamber.

Exchange Controls

The ownership of Class A Shares, Class B Shares or Common Shares of the Company by individuals or legal entities domiciled outside Brazil is subject to certain conditions established under Brazilian law, as described below.

The right to convert dividend payments and proceeds from the sale of shares into foreign currency and to remit such amounts outside Brazil is subject to restrictions under Brazilian foreign investment legislation, which generally requires, among other things, that the relevant investments have been registered with the Brazilian Central Bank. Such restrictions on the remittance of foreign capital abroad may hinder or prevent Itaú Unibanco S.A., as custodian for the Class B Shares represented by ADSs (“Custodian”), or holders who have exchanged ADSs for Class B Shares from converting dividends, distributions or the proceeds from any sale of such Class B Shares, as the case may be, into U.S. dollars and remitting such U.S. dollars abroad. Holders of ADSs could be adversely affected by delays in, or refusal to grant any, required government approval for conversions of Brazilian currency payments and remittances abroad of the Class B Shares underlying the ADSs.

Under Resolution No. 4,373/2014, foreign investors may invest in almost all financial assets and engage in almost all transactions available in the Brazilian financial and capital markets, provided that certain requirements are fulfilled. The definition of foreign investor includes individuals, legal entities, mutual funds and other collective investment entities, domiciled or headquartered abroad.

To be eligible to invest in the Brazilian financial and capital markets, foreign investors must:

| 1. | point at least one representative in Brazil with powers to perform actions relating to foreign investments;

| 2. | register as a foreign investor with the CVM, pursuant to CVM Rule No. 13/2020;

| 3. | register the foreign investment with the Brazilian Central Bank; and

| 4. | constitute at least one custodian institution authorized by CVM, provided that this provision is not applicable to foreign investors who are individuals.

Securities and other financial assets held by foreign investors must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Brazilian Central Bank or the CVM. In addition, securities trading is restricted to transactions carried out in the stock exchanges or organized over-the-counter markets licensed by the CVM.

The Annex II Regulations provide for the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers. Prior to the issuance of the ADSs, the ADS program was approved by the Brazilian Central Bank and the CVM under the Annex V to CMN Resolution No. 2,689, which allowed Brazilian companies to issue depositary receipts in foreign exchange markets and was in force by the time the ADSs were issued. Depositary receipts are currently governed by Resolution No. 4,373. The proceeds from the sale of ADSs by ADS holders outside Brazil are free of Brazilian foreign investment controls and should not be subject to taxation in Brazil. The withdrawal and the disposal of Class B Shares upon cancellation of ADS will be subject to taxation in Brazil. For more information, see “Item 10. Additional Information—Taxation—Brazilian Tax Considerations—Taxation of Gains Outside Brazil”.

An electronic registration has been issued in the name of the Depositary with respect to the ADSs and is maintained by the Custodian on behalf of the Depositary. Pursuant to this electronic registration, the Custodian and the Depositary are able to convert dividends and other distributions with respect to the Class B Shares represented by ADSs into foreign currency and remit the proceeds outside Brazil. In the event that a holder of ADSs exchanges such ADSs for Class B Shares, such holder must seek to obtain its own electronic registration with the Brazilian Central Bank.

Pursuant to Brazilian Central Bank Resolution No. 4,373/2014, the withdrawal of Class B Shares upon cancellation of ADSs may require simultaneous exchange transactions in the event the investor decides not to dispose of those Class B Shares. The simultaneous exchange transactions may be required in order to obtain a certificate of registration of Class B Shares with the Brazilian Central Bank. This transaction will be subject to tax in Brazil. For more information, see “Item 10. Additional Information—Taxation—Brazilian Tax Considerations—Other Brazilian Taxes”.

131

Thereafter, any holder of Class B Shares may not be able to convert into foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, such Class B Shares, unless such holder obtains his own electronic registration. A holder that obtains an electronic registration may be subject to less favorable Brazilian tax treatment than a holder of ADSs. For more information, see “Item 10. Additional Information—Taxation—Brazilian Tax Considerations”.

The Brazilian government may impose temporary restrictions on remittances of foreign capital abroad in the event of a serious imbalance or an anticipated serious imbalance of Brazil’s balance of payments. For approximately six months in 1989 and early 1990, the Brazilian government froze all dividend and capital repatriations held by the Brazilian Central Bank that were owed to foreign equity investors, in order to conserve Brazil’s foreign currency reserves. These amounts were subsequently released in accordance with Brazilian government directives. There can be no assurance that the Brazilian government will not impose similar restrictions on foreign repatriations in the future.

132

Taxation

The following summary contains a description of the principal Brazilian and U.S. federal income tax consequences of the acquisition, ownership and disposition of Class B Shares or ADSs, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to purchase Class B Shares or ADSs. The summary is based upon the tax laws of Brazil and regulations thereunder and on the tax laws of the United States and regulations thereunder as in effect on the date hereof, which are subject to change. Prospective purchasers of Class B Shares or ADSs should consult their own tax advisors as to the tax consequences of the acquisition, ownership and disposition of Class B Shares or ADSs.

Although there is at present no income tax treaty between Brazil and the United States, the tax authorities of the two countries have had discussions that may culminate in such a treaty. No assurance can be given, however, as to whether or when a treaty will enter into force or how it will affect the U.S. holders of Class B Shares or ADSs. Prospective holders of Class B Shares or ADSs should consult their own tax advisors as to the tax consequences of the acquisition, ownership and disposition of Class B Shares or ADSs in their particular circumstances.

Brazilian Tax Considerations

The following discussion summarizes the principal Brazilian tax consequences of the acquisition, ownership and disposition of Class B Shares or ADSs by an individual, entity, trust or organization resident or domiciled outside Brazil for purposes of Brazilian taxation (“Non-Brazilian Holder”). It is based on Brazilian law currently in effect, which is subject to differing interpretations and changes that may apply retroactively. This discussion does not address all the Brazilian tax considerations that may be applicable to any particular Non-Brazilian Holder, and each Non-Brazilian Holder should consult its own tax advisor about the Brazilian tax consequences of investing in Class B Shares or ADSs.

Taxation of Dividends

Dividends paid by the Company in cash or in kind from profits of periods beginning on or after January 1, 1996 (i) to the Depositary in respect of Class B Shares underlying ADSs or (ii) to a Non-Brazilian Holder in respect of Class B Shares generally will not be subject to Brazilian withholding income tax. Dividends paid from profits generated before January 1, 1996 may be subject to Brazilian withholding income tax at varying rates depending upon the year in which the profits have been obtained.

Distributions of Interest on Equity

In accordance with Law No. 9,249, dated December 26, 1995, as amended, Brazilian corporations may make payments to shareholders characterized as distributions of interest on the equity of the company as an alternative form of making dividend distributions. The rate of interest may not be higher than TJLP, as determined by the Brazilian Central Bank from time to time. The total amount distributed as interest on equity may not exceed, for tax purposes, the greater of (i) 50.0% of net income (after the deduction of the social contribution on net profits and before taking into account the provision for corporate income tax and the amounts attributable to shareholders as net interest on equity) related to the period in respect of which the payment is made and (ii) 50.0% of the sum of retained profits and profit reserves as of the date of the beginning of the period in respect of which the payment is made.

Distributions of interest on equity paid to Brazilian and Non-Brazilian Holders of Class B Shares, including payments to the Depositary in respect of Class B Shares underlying ADSs, are deductible by the Company for Brazilian corporate income tax and social contribution on net profits purposes as far as the limits above described are observed. Such payments to shareholders are subject to Brazilian withholding income tax at the rate of 15.0%, except for payments to shareholders situated in tax haven jurisdictions (that is, a country or location that does not impose income tax or where the maximum income tax rate is lower than 20% or where the local legislation imposes restrictions on disclosing the shareholding composition or the ownership of the investment or the beneficial owner of the income derived from transactions carried out and attributable to a Non-Brazilian Holder – “Tax Haven Holder”), which payments are subject to withholding income tax at a 25.0% rate. A regulation issued by the Brazilian tax authorities on November 28, 2014 (Ordinance 488, of 2014) decreased, from 20% to 17%, the minimum threshold for certain specific cases. The reduced 17% threshold applies only to countries and regimes aligned with international standards of fiscal transparency in accordance with rules to be established by the Brazilian tax authorities in Normative Ruling 1,530 dated December 19, 2014. The list of tax haven jurisdictions is currently provided in Normative Ruling No. 1,037. These payments may be included, at their net value, as part of any mandatory dividend. To the extent that payment of interest on net equity is so included, the corporation is required to distribute to shareholders an additional amount to ensure that the net amount received by them, after payment of the applicable withholding income tax, plus the amount of declared dividends, is at least equal to the mandatory dividend.

133

Taxation of Gains Outside Brazil

According to Law No. 10,833 of December 29, 2003 (“Law No. 10,833/03”), capital gains realized on the disposition of assets located in Brazil by a Non-Brazilian Holder, whether to another non-Brazilian resident or to Brazilian residents, are subject to taxation in Brazil. In this sense, if the Class B Shares are disposed of by a Non-Brazilian Holder, as they are defined as assets located in Brazil, such holder will be subject to income tax on the gains assessed, following the rules described below, whether the disposition is conducted in Brazil or abroad and with a Brazilian resident or not.

A disposition of Class B Shares can occur abroad if an investor decides to cancel its investment in ADSs and register the underlying Class B Shares as a direct foreign investment under Law No. 4,131. Any capital gain arising from sales or other dispositions of Class B Shares outside Brazil would be subject to Brazilian income tax at the rates that range from 15% to 22.5% depending on the amount of the gain, as follows: (i) 15% on gains not exceeding R$5,000,000.00; (ii) 17.5% on gains that exceed R$5,000,000.00 and do not exceed R$10,000,000.00; (iii) 20% on gains that exceed R$10,000,000.00 and do not exceed R$30,000,000.00; and (iv) 22.5% on gains exceeding R$30,000,000.00 or, if the investor is a Tax Haven Holder, 25.0%, which should be withheld by the purchaser of the Class B Shares outside Brazil or its attorney-in-fact in Brazil.

Regarding ADSs, although the matter is not free from doubt, the gains realized by a Non-Brazilian Holder on the disposition of ADSs to another Non-Brazilian Holder should not be taxed in Brazil, based on the theory that ADSs do not constitute assets located in Brazil for purposes of Law No. 10,833/03. However, we cannot assure you that Brazilian courts would adopt this theory. Thus, the gain on a disposition of ADSs by a Non-Brazilian Holder to a resident in Brazil (or possibly even to a Non-Brazilian Holder in the event that courts determine that ADSs would constitute assets located in Brazil) may be subject to income tax in Brazil.

Taxation of Gains in Brazil

For purposes of Brazilian taxation, the income tax rules on gains related to disposition of Class B Shares vary depending on the domicile of the Non-Brazilian Holder, the form by which such Non-Brazilian Holder has registered its investment before the Brazilian Central Bank and/or how the disposition is carried out, as described below.

Generally, gains are defined as the positive difference between the amount realized on the sale or exchange of a security and its acquisition cost. Gains assessed on the disposition of the Class B Shares carried out on the Brazilian stock exchange (which includes the transactions carried out on the organized over-the-counter market) are:

| 1. | exempt from income tax when assessed by a Non-Brazilian Holder registered under Resolution No. 4,373 of the CMN (“4,373 Holder”) that is not a Tax Haven Holder; or

| 2. | subject to income tax at a rate of 15.0% in any other case, including the gains assessed by a Non-Brazilian Holder that (i) is not a 4,373 Holder, or (ii) is a 4,373 Holder and is a Tax Haven Holder.

There can be no assurance that the current preferential treatment for 4,373 Holders will continue in the future.

Any other gains assessed on a disposition of the Class B Shares that is not carried out on the Brazilian stock exchange is subject to income tax at the progressive rates ranging from 15% to 22.5%, except for gains assessed by Tax Haven Holders who are subject to an income tax rate of 25.0%.

If these gains are related to transactions conducted on the Brazilian non-organized, over-the-counter market, through an intermediary, the withholding income tax of 0.005% on the sale value shall also be applicable and can be offset with the eventual income tax due on the capital gain.

134

The deposit of Class B Shares in exchange for the ADSs may be subject to Brazilian income tax. In this case, the difference between the acquisition cost and the market price of the Class B Shares would be subject to income tax at the progressive rates ranging from 15% to 22.5% or 25.0% in the case of investors that are Tax Haven Holders. There may be arguments to claim that this taxation is not applicable in the case of a Non-Brazilian Holder that is registered under Resolution 4,373 (other than Tax Haven Holders), which should not be subject to income tax in such a transaction.

The withdrawal of Class B Shares upon cancellation of ADSs should not be subject to Brazilian income tax, as long as the regulatory rules are appropriately observed with respect to the registration of the investment before the Brazilian Central Bank.

In the case of redemption of the Class B Shares or ADSs or capital reduction by a Brazilian corporation, with subsequent withdrawal of the ADSs, such as our company, the positive difference between the amount effectively received by the Non-Brazilian Holder and the acquisition cost of the securities redeemed is treated as capital gain derived from the sale or exchange of shares not carried out on a Brazilian stock exchange market and is therefore subject to income tax at the progressive rates ranging from 15.0% to 22.5% or 25.0%, as the case may be.

Any exercise of preemptive rights relating to the Class B Shares or ADSs will not be subject to Brazilian taxation. Gains on the sale or assignment of preemptive rights will be subject to the same tax treatment applicable to disposition of Class B Shares.

Other Brazilian Taxes

There are no Brazilian inheritance, gift or succession taxes applicable to the ownership, transfer or disposition of Class B Shares or ADSs by a Non-Brazilian Holder except for gift and inheritance taxes levied by some states in Brazil on gifts made or inheritances bestowed by individuals or entities not resident or domiciled in Brazil or in the relevant State to individuals or entities that are resident or domiciled within such State in Brazil. There are no Brazilian stamp, issue, registration, or similar taxes or duties payable by holders of Class B Shares or ADSs.

Pursuant to Decree No. 6,306 of December 14, 2007 (“Decree No. 6,306/07”), a tax on foreign exchange transactions (“IOF/Exchange”) may be imposed on the conversion of Brazilian currency into foreign currency (e.g., for purposes of paying dividends and interest) or vice-versa. Currently, for most exchange transactions, the rate of IOF/Exchange is 0.38%, except for: (i) foreign exchange transactions for the inflow of funds related to investments in variable income effectuated by a Non-Brazilian Holder in the Brazilian financial and capital market, in which case the rate is 0%, and (ii) payment of dividends, and interest on shareholders’ equity related to the investment mentioned under item (i) above, in which case the rate is zero. Nonetheless, the Brazilian government may increase the rate to a maximum of 25.0%. Any such increase will be applicable only prospectively.

Pursuant to Decree No 6,306/07, the Tax on Bonds and Securities Transactions (“IOF/Bonds”) may be imposed on any transactions involving bonds and securities, including those carried out on Brazilian stock, futures and commodities exchanges. The rate of IOF/Bonds Tax applicable to transactions involving common shares is currently zero if the redemption, transfer or renegotiation occurs after 30 days of their acquisition. As from December 24, 2013, the IOF/Bonds levies at a rate of zero percent on the transfer (cessão) of shares traded in a Brazilian stock exchange environment with the specific purpose of enabling the issuance of depositary receipts to be traded outside Brazil. The Brazilian government is permitted to increase such rate at any time up to 1.5% per day, but only in respect of future transactions.

U.S. Federal Income Tax Considerations

The statements regarding U.S. tax law set forth below are based on U.S. law as in force on the date of this annual report, and changes to such law subsequent to the date of this annual report may affect the tax consequences described herein (possibly with retroactive effect). This summary describes the principal U.S. federal income tax consequences of the ownership and disposition of Class B Shares or ADSs, but it does not purport to be a comprehensive description of all of the U.S. tax consequences that may be relevant to a decision to hold or dispose of Class B Shares or ADSs. This summary applies only to purchasers of Class B Shares or ADSs who will hold the Class B Shares or ADSs as capital assets and does not apply to special classes of holders such as brokers or dealers in securities or currencies, holders whose functional currency is not the U.S. dollar, holders of 10% or more of our shares by vote or value (taking into account shares held directly or through depositary arrangements), tax-exempt organizations, financial institutions, holders liable for the alternative minimum tax, securities traders who elect to account for their investment in Class B Shares or ADSs on a mark-to-market basis, regulated investment companies, partnerships or other pass-through entities (or partners or members therein), insurance companies, U.S. expatriates, and persons holding Class B Shares or ADSs in a hedging transaction or as part of a straddle, conversion or other integrated transaction for U.S. federal income tax purposes. Moreover, this summary does not address the Medicare tax on net investment income or the tax consequences to U.S. holders of acquiring, owning or disposing of Class B Shares or ADSs under any U.S. federal estate or gift, state, local or foreign taxes.

135

Each holder is encouraged to consult such holder’s tax advisor concerning the overall tax consequences to it, including the consequences under laws other than U.S. federal income tax laws, of an investment in Class B Shares or ADSs.

In this discussion, references to a “U.S. holder” are to a beneficial holder of a Class B Share or an ADS that is (i) an individual citizen or resident of the United States of America, (ii) a corporation, or any other entity taxable as a corporation, organized under the laws of the United States of America, any state thereof, or the District of Columbia, or (iii) otherwise subject to U.S. federal income taxation on a net basis with respect to the Class B Share or ADS.

For purposes of the U.S. Internal Revenue Code of 1986, as amended, which we call the “Code”, holders of ADSs will generally be treated as owners of the Class B Shares represented by such ADSs.

Taxation of Distributions

A U.S. holder will recognize dividend income for U.S. federal income tax purposes in an amount equal to the amount of any cash and the value of any property distributed by us as a dividend to the extent that such distribution is paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, when such distribution is received by the custodian (or by the U.S. holder in the case of a holder of Class B Shares).

We do not expect to maintain calculations of our earnings and profits in accordance with U.S. federal income tax principles. U.S. holders therefore should expect that distributions generally will be treated as dividends for U.S. federal income tax purpose.

If you are a U.S. holder, the amount of any distribution will include the amount of Brazilian tax withheld on the amount distributed, and the amount of a distribution paid in reais will be measured by reference to the exchange rate for converting reais into U.S. dollars in effect on the date the distribution is received by the custodian (or by a U.S. holder in the case of a holder of Class B Shares). If the custodian (or U.S. holder in the case of a holder of Class B Shares) does not convert such reais into U.S. dollars on the date it receives them, it is possible that the U.S. holder will recognize foreign currency loss or gain, which would be ordinary loss or gain, when the reais are converted into U.S. dollars. Dividends paid by us will not be eligible for the dividends received deduction allowed to corporations under the Code.

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual, with respect to the ADSs, will be subject to taxation at preferential rates if the dividends are “qualified dividends”. Dividends paid on the ADSs will be treated as qualified dividends if (i) the ADSs are readily tradable on an established securities market in the United States and (ii) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”). The ADSs are listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. Based on our audited consolidated financial statements and relevant market and shareholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to our 2019 and 2020 taxable years. In addition, based on our audited consolidated financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for the 2021 taxable year. Based on existing guidance, it is not clear whether dividends received with respect to the Class B Shares will be treated as qualified dividends, because the Class B Shares themselves are not listed on a U.S. exchange. Holders of ADSs and Class B Shares should consult their own tax advisers regarding the availability of the reduced dividend tax rate in light of the considerations discussed above and their own particular circumstances.

136

Distributions with respect to the Class B Shares or ADSs generally will be treated as dividend income from sources outside of the United States and generally will be treated separately along with other items of “passive” income for purposes of determining the credit for foreign income taxes allowed under the Code. Subject to certain limitations, Brazilian income tax withheld in connection with any distribution, with respect to the Class B Shares or ADSs may be claimed as a credit against the U.S. federal income tax liability of a U.S. holder if such U.S. holder elects for that year to credit all foreign income taxes. Alternatively, such Brazilian withholding tax may be taken as a deduction against taxable income. Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions and may not be allowed in respect of arrangements in which a U.S. holder’s expected economic profit, after non-U.S. taxes, is insubstantial. U.S. holders should consult their own tax advisors concerning the implications of these rules in light of their particular circumstances.

Distributions of additional shares to holders with respect to their Class B Shares or ADSs that are made as part of a pro rata distribution to all our shareholders generally will not be subject to U.S. federal income tax.

Holders of Class B Shares or ADSs that are foreign corporations or nonresident alien individuals, which we call “non-U.S. Holders”, generally will not be subject to U.S. federal income tax or withholding tax on distributions with respect to Class B Shares or ADSs that are treated as dividend income for U.S. federal income tax purposes unless such dividends are effectively connected with the conduct by the holder of a trade or business in the United States.

Taxation of Capital Gains

Upon the sale or other taxable disposition of a Class B Share or ADS, a U.S. holder will recognize gain or loss for U.S. federal income tax purposes. The amount of the gain or loss will be equal to the difference between the amount realized in consideration for the disposition of the Class B Share or ADS (including the gross amount of the proceeds before the deduction of any Brazilian tax) and the U.S. holder’s tax basis in the Class B Share or ADS. Such gain or loss generally will be subject to U.S. federal income tax as capital gain or loss and will be long-term capital gain or loss if the Class B Share or ADS has been held for more than one year on the date of the disposition. The net amount of long-term capital gain recognized by an individual holder generally is subject to taxation at preferential rates. Capital losses may be deducted from taxable income, subject to certain limitations. Gain realized by a U.S. holder on a sale or disposition of Class B Shares or ADSs generally will be treated as U.S. source income for U.S. foreign tax credit purposes. Consequently, if Brazilian tax is imposed on such gain, the U.S. holder will not be able to use the corresponding foreign tax credit, unless the holder has other foreign source income of the appropriate type in respect of which the credit may be used. Alternatively, such Brazilian tax may be taken as a deduction against taxable income if the U.S. holder does not take a credit for any foreign income tax during the taxable year.

A non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax on gain realized on the sale or other disposition of a Class B Share or ADS unless (i) such gain is effectively connected with the conduct by the holder of a trade or business in the United States, or (ii) such holder is an individual who is present in the United States of America for 183 days or more in the taxable year of the sale and certain other conditions are met.

Foreign Financial Asset Reporting

Certain U.S. Holders that own “specified foreign financial assets” with an aggregate value in excess of US$50,000 on the last day of the taxable year or US$75,000 at any time during the taxable year are generally required to file an information statement along with their tax returns, currently on Form 8938, with respect to such assets. “Specified foreign financial assets” include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions. The understatement of income attributable to “specified foreign financial assets” in excess of US$5,000 extends the statute of limitations with respect to the tax return to six years after the return was filed. U.S. Holders who fail to report the required information could be subject to substantial penalties. Prospective investors are encouraged to consult with their own tax advisors regarding the possible application of these rules, including the application of the rules to their particular circumstances.

137

Backup Withholding and Information Reporting

Dividends paid on, and proceeds from the sale or other disposition of, the ADSs or Class B Shares to a U.S. holder generally may be subject to the information reporting requirements of the Code and may be subject to backup withholding unless the U.S. holder (i) is a corporation or other exempt recipient or (ii) provides an accurate taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. The amount of any backup withholding collected from a payment to a U.S. holder will be allowed as a credit against the U.S. holder’s U.S. federal income tax liability and may entitle the U.S. holder to a refund, provided that certain required information is furnished to the Internal Revenue Service.

A non-U.S. Holder generally will be exempt from these information reporting requirements and backup withholding tax, but may be required to comply with certain certification and identification procedures in order to establish its eligibility for such exemption in connection with payments received within the United States or through certain U.S.-related intermediaries.

138

Item 12D. American Depositary Shares

In the United States, the Class B Shares trade in the form of ADSs, each representing one Class B Share, issued by The Bank of New York Mellon (or the Depositary) pursuant to the Deposit Agreement. The ADSs trade under the symbols ELP and ELPVY. ADS holders are required to pay various fees to the Depositary, and the Depositary may refuse to provide any service for which a fee is assessed until the applicable fee has been paid. The Depositary is located at 240 Greenwich Street, New York, NY 10286.

ADS holders are required to pay the Depositary: (i) an annual fee of up to US$0.02 per ADS (or portion thereof) for administering the ADS program, and (ii) amounts in respect of expenses incurred by the Depositary or its agents on behalf of ADS holders, including expenses arising from compliance with applicable law, taxes or other governmental charges, cable, telex and facsimile transmission, or conversion of foreign currency into U.S. dollars. In both cases, the Depositary may decide in its sole discretion to seek payment by either billing holders or by deducting the fee from one or more cash dividends or other cash distributions.

ADS holders are also required to pay additional fees for certain services provided by the Depositary, as set forth in the table below.

139

Depositary service | Fee payable by ADS holders
Issuance of ADSs, including issuances resulting from a distribution of shares or rights or other property | US$5.00 or less per 100 ADSs (or portion thereof)
Cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates | US$5.00 or less per 100 ADSs (or portion thereof)
Distribution of cash dividends | US$0.02 or less per ADS

(a) Disclosure Control and Procedures

We evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2020 with the participation of our Chief Executive Officer and Chief Financial Officer. Based on our assessment, we concluded that, as of December 31, 2020, our disclosure controls and procedures were effective in providing reasonable assurance that information that we are required to disclose in the reports we present or submit under the Exchange Act is recorded, processed, summarized and reported, within the deadlines specified in the applicable rules and forms, and are accumulated and reported to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding any required disclosure.

(b) Management Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for evaluating the effectiveness of internal control over financial reporting. The process of internal controls over financial reporting is designed by our Chief Executive Officer and our Chief Financial Officer, under the supervision of our Board of Directors, and is carried out by our management and other employees as a means to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with IFRS, issued by the IASB.

140

Rules 13a-15(f) and 15d-15(f) under the Exchange Act define internal control over financial reporting as a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes policies and procedures that (1) refer to record keeping that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to enable the preparation of financial statements in accordance with generally accepted accounting principles, and that Company’s receipts and expenses are being made only with authorization from Company's management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Company's assets that could have a material effect on the audited consolidated financial statements.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any assessment of effectiveness for future periods are subject to numerous risks, including that controls may become inadequate due to changes in conditions.

Our management has assessed the effectiveness of our internal controls over financial reporting as of December 31, 2020, was based on the criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on such assessment and criteria applied, our management has concluded that, as of December 31, 2020, the Company's internal control over financial reporting is effective.

Our independent registered public accounting firm has examined the effectiveness of our internal control over financial reporting, as indicated in the report included in this document.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of
Companhia Paranaense de Energia - Copel

Curitiba - PR, Brazil

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Companhia Paranaense de Energia - Copel and subsidiaries (the “Company”) as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013), issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020 of the Company and our report, dated April 19, 2021, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

(d) Changes in Internal Control on Financial Reporting

The Company's management implemented changes to its internal control over financial reporting during the year ended December 31, 2020 related to coping with the COVID-19 pandemic, in which a portion of our employees began working remotely, as highlighted below:

| · | Improvements in information security procedures related to the home office, with the implementation of VPN tools, release of remote accesses securely and tested according to the 'Safe Home office' (‘Homeoffice Seguro’) and pentest (Cyber Penetration Test) initiatives, carried out periodically;

| · | Conducting awareness campaigns for employees regarding cybersecurity, home office, LGPD, and access control;

| · | Improvement in the procedures and controls that were reviewed in order to mitigate the risks related to the performance of remote activities;

| · | Implementation of a second authentication factor for some areas of the company considered critical.

The Company's management has not identified any other changes in its internal control over financial disclosure reporting during the year ended December 31, 2020 that has significantly affected, or is reasonably likely to materially affect, its internal control over financial reporting, except with respect to the remediation listed below.

Material weakness identified as of December 31, 2019

As of December 31, 2019, we reported a material weakness related to internal control deficiencies over the review of assumptions and the calculation of the impairment loss of fixed assets of Copel Telecomunicações, a wholly owned subsidiary of the Company, and of UEGA, a non-wholly owned subsidiary of the Company.

This material weakness arose from difficulties in the operational effectiveness of the control related to the review of assumptions and the calculation of the impairment loss of fixed assets of Copel Telecomunicações and UEGA.

In response to this material weakness, the Company adopted measures to mitigate the risks through a series of actions involving changes in procedures and creation of controls, which were implemented throughout 2020.

Among the main actions and internal controls that have been improved and implemented by the Company, the following stand out:

| · | Intensification of training and communication procedures to all employees involved in these processes, including concepts of internal controls, as well as the operational aspects of calculating the impairment loss;

| · | Improvement in procedures and controls so that all impairment reduction tests are duly reviewed by another qualified Company employee, by means of a checklist created for this purpose;

| · | Improvement in the existing controls and procedures for internal evaluation of all possible impacts of the impairment indicators;

| · | Improvement in the controls to ensure the correct analysis of asset recoverability, including meetings to define the assumptions, calculations for the Company's assets formally reviewed and approved by the competent technical area in the Company, as well as the issuance of an impairment memorandum signed by the Officer.

Remediation of material weakness reported as of December 31, 2019

In order to remedy the material deficiency identified in fiscal year of 2019, the Company's management relied on the support of the Internal Controls Coordinator and specialists representing each department to analyze and establish immediate actions to remedy these notes. The actions taken were reported periodically to the Statutory Audit Committee, the Fiscal Council and the Board of Directors throughout 2020.

142

We emphasize that the Company has been working continuously to improve its internal control environment. With the support of a consulting company engaged to provide advisory services for work related to Internal Controls, we have established action plans to mitigate the risks and periodically communicate them to the governance bodies.

As a result of the work carried out by the management, the Company has successfully remedied the material weakness that had been reported in our previous year's report.

Item 16B. Code of Ethics

We highlight the review carried out in 2015, when a public consultation to stakeholders took place, and the 2017 review that started to reflect the new Brazilian regulations on conflict of interests and periodic training. The current version of the Code of Conduct was approved on March 13, 2018 by the Board of Directors. In 2019, we began a new process of reviewing our Code through public consultation, which is expected to be completed in early 2021.

The Code of Conduct applies to all of our employees, interns, suppliers, service providers, contractors, directors and officers (including our Chief Executive Officer, our Chief Financial Officer and the officer in charge of our accounting department), as well as of our wholly-owned subsidiaries. Since the adoption of our Code of Conduct, we have not granted any express or implied waiver of any section of our code to the persons to whom it applies.

To the Shareholders and Board of Directors of

Companhia Paranaense de Energia - Copel

Curitiba - PR, Brazil

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Companhia Paranaense de Energia - Copel and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with International Financial Reporting Standards - IFRS as issued by the International Accounting Standards Board - IASB.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 19, 2021, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission - SEC and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

156

Emphasis of Matter

COVID-19-Related Matters

As discussed in Note 1 to the financial statements, the Company has described the impacts of the coronavirus disease (COVID-19) on the operations of the business and the uncertainties of related future impacts on the business, as well as the measures, both taken and planned, to deal with these events and circumstances. Our opinion is not modified in respect of this matter.

Reclassification of RBSE Asset from Accounts Receivable - Concessions to Contract Assets

As discussed in Note 3.6.1, the accompanying financial statements for the year ended December 31, 2019 have been restated for the reclassification of the RBSE Asset from Accounts receivable - Concessions to contract assets. Our opinion is not modified in respect of this matter.

Assets Held for Sale and Discontinued Operations

Share Split

As discussed in Note 3.6.3, earnings per share and per share amounts of dividends reflect the effects of the share split on March 11, 2021. Our opinion is not modified in respect of this matter.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue Recognition - Refer to Notes 4.12 and 31 to the Financial Statements

Critical Audit Matter Description

The Company bills its residential, industrial and commercial customers monthly. Unbilled revenues from the billing date to month-end are estimated based on the prior month’s billing and recognized as revenue at the end of the month in which the service was provided. At the end of each month, the amount of energy delivered to the customers since their last meter reading date is estimated and the corresponding unbilled revenue is determined based upon a customer’s daily estimated usage by class and applicable customer rates reflecting significant historical trends and experience. Differences between estimated and actual unbilled revenues are recognized in the following month.

We identified revenue recognition as a critical audit matter because of the judgments necessary to audit the revenue recognition, including the methods and assumptions used to estimate unbilled revenue, as well as the use of automated systems to process and record revenue. Performing procedures to audit revenue required a high degree of auditor judgment and extensive audit effort, including involvement of our Information Technology - IT specialists.

157

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures on revenue recognition included the following, among others:

| · | We tested the effectiveness of controls over revenue recognition, including Management’s controls over the measurement of energy volumes and pricing, as well as controls over estimates of unbilled revenue.

| · | With the assistance of our IT specialists, we:

| - | Identified the significant systems used to process revenue transactions and tested the general IT controls over each of these systems, including testing of user access controls, change Management controls, and IT operations controls.

| – | Performed testing of system interface controls and automated controls within the relevant revenue streams, as well as the controls designed to ensure the accuracy and completeness of revenue.

| · | With respect to unbilled revenue, we:

| - | Evaluated the appropriateness and consistency of the methods and assumptions used by Management to develop the estimates of unbilled revenue.

| - | Tested the mathematical accuracy of Management’s estimates of unbilled revenue.

| - | We evaluated Management’s ability to estimate unbilled revenue accurately by comparing actual subsequent revenue with Management’s historical estimates for the related revenue streams.

| · | For a sample of revenue transactions, we performed detail transaction testing by agreeing the amounts recognized to source documents, testing the mathematical accuracy of the recorded revenue, and verifying subsequent cash receipts.

| · | We assessed whether the disclosures made by Management in the financial statements are appropriate.

Impairment of Long-lived Assets - Refer to Notes 4.10 and 17.5 to the Financial Statements

Critical Audit Matter Description

Long-lived assets, primarily property, plant and equipment and intangible assets, comprise a significant amount of Company’s total assets. Management evaluates the long-lived assets and makes judgments and estimates concerning the carrying value of these assets, including the amounts to be capitalized, the depreciation/amortization rates and useful lives of these long-lived assets. The carrying values of these assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount is not recoverable. This requires Management to make long-term forecasts of future revenues and costs related to the assets subject for review. These forecasts require assumptions about the demand for its products and services, future market conditions and regulatory developments. Significant and unanticipated changes to these assumptions could require a provision for impairment in a future period.

We identified impairment of long-lived assets, specifically property, plant and equipment, as a critical audit matter because of the significant estimates and assumptions Management makes to estimate the recoverable amount of property, plant and equipment. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit procedures to evaluate the reasonableness of Management’s estimates and assumptions related to forecasts of future revenues, operating margins and selection of the discount rates.

158

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to impairment of long-lived assets included the following, among others:

| · | We tested the effectiveness of controls over Management’s impairment evaluation of property, plant and equipment, including those over the identification of impairment indicators and the determination of the recoverable amount, such as controls related to Management’s forecasts, the selection of discount rates and mathematical accuracy of the models used by Management.

| · | We evaluated the reasonableness of Management’s forecasts and challenged the assumptions and critical judgments, by considering (1) historical results, (2) contractual and market conditions, including price and energy quantities, and (3) impact of changes in the regulatory environment, also considering the potential effects arising from the COVID-19 pandemic.

| · | With the assistance of our fair value specialists, we evaluated the discount rates, including testing the underlying source information and the mathematical accuracy of the calculations, and developing a range of independent estimates and comparing those to the discount rates selected by Management.

| · | With the assistance of our technical standard and accounting professionals’ specialists to assess the concepts used in the long-lived assets impairment test, we assessed whether the disclosures made by Management in the financial statements are appropriate.

Provisions for Legal Claims and Contingent Liabilities - Refer to Notes 4.11 and 29
to the Financial Statements

Critical Audit Matter Description

The Company is part in several judicial and administrative proceedings before different courts. Based on assessments made by the Company’s legal counsel, Management makes provisions for legal claims in which losses are rated probable, thus meeting the criteria for recognition of provisioning. The Company’s Management believes that it is not practicable to provide information regarding the expected timing of any cash outflows resulting from these lawsuits in which the Company and its subsidiaries are involved, due to the slow pace and unpredictability of Brazilian legal, tax and regulatory systems, and since final resolution of the proceedings for which a provision has been registered depends on the conclusions of court proceedings.

We identified provisions for legal claims and contingent liabilities as a critical audit matter because of the large number of cases and the subjectivity of estimating the likelihood and amount of potential losses, performing audit procedures to evaluate whether legal claim provisions were appropriately recorded and disclosed, requiring a high degree of auditor judgment and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to provision for loss on legal claims included the following, among others:

| · | We tested the effectiveness of controls related to provisions for legal claims and contingent liabilities, including those over the completeness and review of new and outstanding legal matters, as well as controls over the measurement of potential losses.

| · | With the assistance of our IT specialists, we tested the effectiveness of controls related to the computerized systems used by Management to manage outstanding cases.

| · | We tested the integrity and accuracy of the database used by Management to manage outstanding cases and used to determine loss probabilities and measure potential losses.

159

| · | We inquired internal and external legal counsel to understand developments in legal matters and progression in potential settlement discussions.

| · | We requested and received a written response from internal and external legal counsel as it relates to lawsuits.

| · | We read Board of Directors and Executive meeting minutes for evidence of unrecorded contingencies.

| · | We evaluated the assumptions and judgments used by Management to estimate legal and other provisions, including corroborating the assumptions with internal legal counsel, with the assistance of our tax and environmental specialists.

| · | We evaluated the Company’s disclosures for consistency with our knowledge of the Company’s legal matters.

Assets Held for Sale and Discontinued Operations - Refer to Note 40 to the
Financial Statements

Critical Audit Matter Description

After announcing the Board of Directors approval for the divestment of 100% of the Company’s interest held in Copel Telecomunicações S.A. on July 15, 2020 and after obtaining additional required approvals for the planned public auction, Copel Telecomunicações S.A. was classified as available for sale and reported as a discontinued operation effective September 16, 2020 under IFRS 5 - Non-current Assets Held for Sale and Discontinued Operations. After conclusion of the public auction in November 2020, a Share Purchase and Sale Agreement (CCVA) was signed with the winning bidder in January 2021.

We identified assets held for sale and discontinued operations as a critical audit matter because of the size of the transaction and high degree of judgment and subjectivity necessary to determine when the assets held for sale and discontinued operations criteria according to IFRS 5 were met, requiring the use of technical knowledge and interpretation of the accounting standard, as well as the high degree of auditor judgment and effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to provision for assets held for sale and discontinued operations included the following, among others:

| · | We tested the effectiveness of controls relating to Management’s process over disclosures of held-for-sale assets and liabilities/discontinued operations in the financial statements.

| · | We tested the completeness and accuracy of the disclosures regarding held-for-sale assets and liabilities/discontinued operations, including its measurements and timing.

| · | We compared the selling price for the Copel Telecomunicações business to the carrying value of the businesses.

| · | We read the minutes of the Board of Directors which evidenced authorization and approval of the transaction.

| · | With the assistance of our technical standard and accounting professionals’ specialists, we evaluated Management’s application of IFRS 5 for classification of held-for-sale assets and liabilities/discontinued operations.

| · | We assessed whether the disclosures made by Management in the financial statements are appropriate.

160

Recognition of PIS and Cofins Liability to Be Refunded to Consumers - Refer to Note 13.2.1
to the Financial Statements

Critical Audit Matter Description

On June 16, 2020, a final unappealable ruling court decision acknowledged Copel Distribuição’s right to exclude from the PIS and Cofins tax basis the full ICMS amount included in its energy supply and distribution invoices, as well as authorizing Copel to use the tax credit to pay current taxes, related to the period from August 2004 to June 2020. Considering the favorable ruling, Copel Distribuição recognized the updated tax credit in assets. Also, based on the opinion of its legal counsel, the Company recorded the estimated liability to be refunded to consumers for the past ten years of the credit, as from the date of the unappealable decision, considering the current legislation, the statute of limitations period defined in the civil code and jurisprudence.

We identified the recognition of PIS and Cofins liability to be refunded to consumers as a critical audit matter because of the size and complexity of the transaction and high degree of judgment and subjectivity necessary to estimate the Company’s estimated liability amount to be refunded, requiring use of technical knowledge and interpretation of applicable legislation. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our tax and tax legal specialists, when performing audit procedures to evaluate the rationale and challenge Management’s assumptions and judgment.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the provision for recognition of PIS and Cofins liability to be refunded to consumers included the following, among others:

| · | We tested the effectiveness of controls related to Management’s process to recognize transactions of such nature.

| · | With the assistance of our tax specialists, we tested the reasonableness of Management’s methodology used and measurement of the tax credit, including its original amount and monetary correction, which are also the basis for the liability recognized.

| · | We tested the completeness and accuracy of the database used by Management to calculate the tax credits and liability.

| · | With the assistance of technical standard and accounting professionals’ specialists and our tax legal specialists, we analyzed the legal opinions prepared by the Company’s legal specialists (in-house and outside legal counsel) with respect to the evaluation of the liability recognition and understanding its rationale, as well as challenged the Company’s assumptions and judgment.

| · | We assessed whether the disclosures made by Management in the financial statements are appropriate.

Cyber-attack - Refer to Note 41.2 to the Financial Statements

Critical Audit Matter Description

In January 2021, Copel became aware that it was exposed to a cyber incident in its IT environment that interrupted some systems, partially affected the Company’s administrative operations and caused a possible data breach. Management has been conducting a comprehensive containment and remediation effort with respect to the vulnerabilities, extent and consequences of the cyber-attack, involving external cybersecurity and IT general control specialists, to contain and mitigate the incident, such as data breach, among others. The Company has no indication that the accuracy and completeness of the financial information have been affected as a result of the incident.

161

We identified the cyber incident as a critical audit matter since Copel depends on its IT structure for operation processing and preparation of its financial statements. The potential non-adequacy of the IT general control environment and its IT-dependent controls could give rise to the incorrect processing of critical information used in preparing the financial statements, as well as modify information and cyber security-related risks. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve IT and cyber incident response specialists, when performing audit procedures to evaluate the extent of possible consequences to the IT environment.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the cyber-attack included the following, among others:

| · | We assessed the effects of the cyber-attack on the effectiveness of the Company’s and its subsidiaries’ internal control activities, IT environment and data security.

| · | With the assistance of our IT and cyber incident response specialists, we analyzed the extent of the possible consequences to the IT environment and the actions taken by Management to improve the IT security control environment.

| · | For a sample of transactions, we performed additional detail testing on accounting journal entries recorded during the incident period, in order to assess whether there were impacts to the Company’s financial statement information.

| · | We evaluated the impacts of the cyber-attack arising from a possible breach of sensitive data and information, considering Brazilian legislation, as well as other applicable laws.

| · | With the assistance of our technical standard and accounting professionals’ specialists, we evaluated the impacts arising from the cyber-attack on the Company’s financial statements and internal control environment.

| · | We assessed whether the disclosures made by Management in the financial statements are appropriate.

Transmission Contract Assets - Refer to Note 3.6.1 to the Financial Statements

Critical Audit Matter Description

On December 1, 2020, the Brazilian Securities and Exchange Commission (CVM) published Circular Letter/CVM/SNC/SEP/04/2020 (Circular Letter 04/2020), which provided complementary interpretative guidance on aspects of IFRS 15 - Revenue from Contracts with Customers and IFRS 9 - Financial Instruments to be observed when preparing the financial statements by electric transmission companies.

We identified transmission contract assets as a critical audit matter because of judgments necessary to assess the effects of Circular Letter 04/2020, which required the use of technical knowledge and the interpretation of the context applicable to the matter as well as the high degree of auditor judgment and increased extent of effort involved.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to transmission contract assets included the following, among others:

| · | We tested the effectiveness of controls related to Management’s process to measure, classify and disclose transmission contract assets in the financial statements.

| · | We assessed the criteria used by Management to measure, classify and disclose transmission contract assets, including the effects arising from Circular Letter 04/2020.

162

| · | We tested the completeness and accuracy, on a sample basis, of the transmission contract assets.

| · | With the assistance of our technical standard and accounting professionals’ specialists, we evaluated the Company’s adequacy with respect to the concepts used to measure, classify and disclose transmission contract assets, including the effects arising from Circular Letter 04/2020, in the Company’s financial statements.

| · | We assessed whether the disclosures made by Management in the financial statements are appropriate.

1 | Operations

Companhia Paranaense de Energia (Copel or Company), with its head office located at Rua Coronel Dulcídio, 800, Curitiba - State of Paraná, is a publicly-held mixed capital company controlled by the State of Paraná and its shares are traded at Corporate Governance Level 1 of the Special Listing Segments of B3 S.A. - Brasil, Bolsa Balcão Stock Exchange and also on the New York Stock Exchange (NYSE) and on the Madrid Stock Exchange, in the Latin American segment (Latibex).

The core activities of Copel, which are regulated by the Brazilian Electricity Regulatory Agency (ANEEL), linked to the Brazilian Ministry of Mines and Energy (MME), are to carry out research, study, planning, and asset building activities related to the generation, transformation, distribution and trading of energy in any of its forms, primarily electricity. Furthermore, Copel participates in consortiums and in private sector and mixed-capital companies for the purpose of engaging in activities, primarily in the fields of energy, telecommunications and natural gas.

a) | Coronavirus pandemic (Covid-19) and its impacts

Coronavirus is a family of viruses was discovered in 2019 after cases registered in China and causes the disease called Covid-19, which has clinical symptoms ranging from asymptomatic infections to severe respiratory conditions.

On February 26, 2020 the first case of infection was identified in Brazil, in the city of São Paulo and on March 11, 2020, who attributed the status of pandemic to coronavirus, in view of the spread of contamination throughout the world. In Brazil, federal, state and municipal governments have implemented several measures to deal with the public health emergency. In the state of Paraná, measures included social isolation and restrictions on the operation of non-essential activities as means to slow the spread of the disease. These measures were relaxed from September 2020 with the reduction of social isolation and the increase in economic activity; however, in mid-February and early March 2021 the stricter restrictions returned due to the worsening of the pandemic.

As of March 2020, Copel's Management issued rules that aim to ensure compliance with the measures to contain the spread of the disease in the Company and minimize its impacts and potential impacts on the administrative, operations and economic-financial areas.

Accordingly, Copel established a Contingency Commission, whose objective is to monitor and mitigate the impacts and consequences in the main activities of the Company, The 4 pillars defined are: (i) safety of personnel, (ii) continuity of essential activities, (iii) monitoring of the guidelines and requirements of regulatory bodies, and (iv) preservation of adequate financial conditions to withstand the crisis.

Among the main initiatives implemented by the Company, there are actions to prevent and mitigate the effects of contagion in the workplace, such as: adoption of home office in areas where it is possible to adopt this format, travel restrictions, meetings by video conference, daily monitoring of the health and well-being of employees and contingency protocols in order to fully maintain the operations of the electric power,

telecommunications and piped gas infrastructure, preserving the health of its professionals, their safe access to locations, an environment that preserves distance between individuals, hygiene and access to personal protective equipment.

Likewise, Copel has adopted several activities in favor of its customers, maintaining the reliability and availability of its plants, the transmission and distribution systems of electric power and gas and telecommunications, so that they can remain connected and take advantage of Company services in this critical moment of pandemic and social distancing. Copel and its employees go to great lengths to ensure that their customers and family members have healthy and safe in their homes, maintaining all the services that contribute to providing comfort and connectivity for everyone.

Effects from coronavirus (Covid-19) on the financial statements

The drop in growth and the downturn in certain business segments, resulting from the suspension of certain businesses and activities caused by the coronavirus outbreak, have been affecting performance of the Brazilian economy, with effects on Copel's operations, mainly due to the reduction in electric energy demand in the regulated market, which was affected more intensely in the industrial and commercial consumption classes, which registered a decrease of 12.6% and 11.8% in the year, respectively, in relation to the previous year. However, the residential class registered a growth of 5.5% in the year, mainly influenced by measures of social isolation.

On April 8, 2020, valid until August 5, 2020, Provisional Measure 950 was enacted by the Federal Government, which provides for temporary emergency measures for the energy sector due to the declared state of public calamity, establishing an exemption in energy tariffs, funded by the energy sector charge called Energy Development Account - CDE, for low-income consumers with consumption of up to 220 kWh/month, for a period of three months, and providing funds through a credit operation aimed at providing financial relief to energy distributors. On the same date, Aneel published Normative Act 986, authorizing the Electric Energy Trading Chamber - CCEE during 2020, to pass on to the sector agents, with consumption characteristics, the surplus funds available in the reserve fund for future burden relief, with the objective of strengthening the sector's liquidity during the virus pandemic.

On April 8, 2020 and May 13, 2020, the Company obtained access to funds amounting to R$ 84,881 and R$ 8,666, respectively, which were recorded as sector financial liabilities.

On May 18, 2020, Decree 10,350 was enacted, which provided for the creation of the Covid Account, intended for the electric sector to deal with the state of public calamity recognized by Legislative Decree 6, of March 20, 2020, and which regulated the Provisional Measure 950 valid until August 5, 2020. On June 23, 2020, Aneel issued Resolution 885, which provides for the Covid Account, financial operations, the use of the CDE for these purposes and the corresponding procedures.

These measures are intended to balance cash of energy distribution companies and prevent the effects from default and reduced energy consumption during the coronavirus pandemic from affecting the entire sector, as well as easing tariff pressure on consumers, in 2020, due to the windfall costs arisen in the context of the Covid-19 pandemic.

Copel has filed the Statement of Acceptance of the Provisions of Decree 10,350/2020. The total amount requested was R$ 869,516, and on June 25, 2020, had already expressed its position about the advance of R$ 536,359 referring to the recognized CVA, which was part of its annual tariff adjustment. The total amount requested was fully received on July 31, 2020.

It should be noted that the provisional measure did not reach energy contracts entered into in the free market. To reduce the impact on revenue from this market and to avoid future legal disputes, Copel renegociated with its customers, with difficulty in fulfilling contracts, proposing payments in installments and postponing maturity of energy bills.

In relation to the captive distribution market, Copel has been posting decrease in revenue, mainly in the commercial and industrial classes, which reduced consumption by 11.8% and 12.6%, respectively, reflecting the fall in economic activities, mainly when stricter restrictions are implemented in an attempt to reduce the level of contagion among the population. On the other hand, there has been an increase in revenue in the residential class, due to the social distancing measures, and in the rural class, reflecting the good performance of agribusiness in the Paraná state. With regard to collection, the Company has been in contact with its main customers and has made the collection policy more flexible during the pandemic period, as such, there has been an increase in number of payments in installments.

Due to the measures applied by Aneel in the context of Covid-19, the Company has not suspended energy supply to residential customers and to essential services and activities until July 31, 2020. In this respect, with the health crisis there has been an increase of R$ 35,800 in estimated expected credit losses recorded by Copel DIS no 1st semester de 2020, due to the increase in consumers' default, coupled with the drop in collection and the stoppage of several commercial and industrial activities resulting from the social distancing measures, this reducing Copel DIS's financial and economic results. With the 3.1% drop in consumption of the captive energy market for the year, due to the pandemic scenario, the Company estimates over-contracting of 105.5% of electricity in 2020 at Copel DIS. However, as described in Note 35.2.9, the Company understands that this overcontracting will be considered involuntary.

Copel has been monitoring energy load projections and has not seen any signs of significant retraction in the beginning of 2021, which may occur if restrictions have a long-term impact on non-essential industrial and commercial activities.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

Another point for attention are the possible impacts on the implementation schedule of energy generation and transmission projects, or even on the availability of existing assets resulting from local actions that prevent access to facilities or problems with suppliers in the sector, also affected by the downturn. Management, diligently, continues to monitor the deadlines for construction works in progress and has maintained continuous communication with the concession regulator regarding any delays that may occur until the normalization of commercial activities in the overall market. The Company's construction in progress to date have not had any significant delays.

With the objective of mitigating the impacts and consequences on its main activities, Copel has been continuously monitoring its contracts, liquidity in the energy market and the short-term energy price, as well as the negotiations with the Regulatory Body of the Brazilian energy sector for the implementation of guidelines ensuring maintenance of economic and financial sustainability of the entire chain of energy generation, transmission, sale and distribution.

In this scenario, for the purposes of preparing and disclosing the financial statements for the year ended December 31, 2020, the Company's management evaluated its estimates in order to identify the possible impacts of Covid-19 on the Company's business, as follows:

a.1) Expected credit losses

A potentially relevant risk in the emergence of Covid-19 is related to customer default. In this scenario, the Company maintains regular contact with its main customers, adding flexibility to the collection policy during the pandemic period and increasing the level of digitalization in the relationship with Copel.

The Company's accounts receivable position as of December 30, 2020, as well as the estimates of expected credit losses reflect in a timely manner the best analysis by Management at this time on the quality and recoverability of this financial asset.

Although the loss indicator has not significantly deteriorated, the Company may face pressure on this indicator if the pandemic lasts longer and stricter restrictions on social distancing are implemented as an attempt to reduce the level of transmission among the population.

In 2020, Copel’s expected credit loss estimates were more impacted in the first half-year, mainly due to regulatory restrictions that prevented, until July 31, 2020, cuts in the supply of energy to defaulting customers, as well as the greater restriction in social isolation in that period. In the second half of 2020, the loss estimates were less impacted due to the easing of social isolation that led to a resumption of economic activity, the continuity of cuts in the supply of energy and the renegotiation with defaulting customers.

On March 26, 2021, Aneel Resolution No. 928 was issued, which prevents the suspension of energy supply to low-income consumers and some other groups of consumers, with no material impact for the Company, given that these consumers are already covered by the State Law No. 20,187 / 2020, which also deals with the prohibition on cutting the power supply.

Despite the worsening of the pandemic at the beginning of 2021, Copel resumed collection actions with defaulting consumers and created special conditions for payment of debts, giving conditions to consumers affected by the restrictions of social distance, necessary to prevent the spread of the virus, in keeping up with their obligations to the Company.

a.2) Impairment of non-financial assets - impairment

The assumptions for all non-financial assets were assessed individually and the conclusion is that the net carrying amount of the assets is recoverable.

F-11

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

The assumptions in connection with the Company's material non-financial assets were assessed individually and Management concluded that it is necessary to adjust the amount of impairment for some assets, as shown in Note 17.

Despite the hydrological scenario in southern Brazil in 2020 benefiting the dispatch of the thermoelectric plant, the most significant impairment adjustment occurred at UEG Araucária, in view of the more gradual expectation of a resumption of energy demand, which affected its long term cash flow estimates, which makes the plant's consumption assumptions occur in a shorter period than the previous projections.

For the other projects, there was an impairment reversal, as presented in Note 17.5. In relation to the projections, the main assumptions applied in the preparation of cash flow models did not have a significant impact in the short term, given that most of the energy is already contracted and the amount of energy exposed to Settlement Price of the Differences (PLD) is not significant. In the medium term, there was impact on the prices negotiated in the free market on the portion of non-contracted energy, but with no significant impact for the Company. Finally, in the long term, the main assumptions used to calculate the impairment (future energy prices and Generation Scaling Factor - GSF levels) did not change significantly, accordingly evidencing the recoverability of assets.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

a.3) Recovery of deferred tax assets

The Company has a balance of R$ 1,191,104 related to deferred tax assets on income tax and social contribution losses and temporary differences recorded at December 31, 2020. The Company assessed its estimates of expected future taxable income and did not identify the need for a provision for loss.

a.4) Fair value of future energy purchase and sale operations

The effects of pandemic on the mark-to-market of electric power purchase and sale agreements occurred mainly in the variation of short-term future prices due to more favorable hydrology and load reduction. In the long-term, future electric power prices did not change significantly. Therefore, at this time, the effects of the pandemic did not have a significant impact on the fair value of the Company's future energy purchase and sale operations.

a.5) Fair value of other assets and liabilities

At the present time, the effects of the pandemic did not have a significant impact on the fair value of the Company's assets and liabilities, mainly on assets originating from concession agreements that are made in the long-term and are contractually guaranteed to receive residual balance at the end of the concession and/ or right to receive cash during the concession. Accordingly, considering that there were no changes in long-term estimates and assumptions, and that the Company's assets are essential and indicate continuity of operations and cash flows in the medium and long term, up to the present date, despite the fact that the pandemic effects remain uncertain, its effects did not have a significant impact on the fair value of the Company's assets and liabilities.

a.6) Post-employment benefits

The Company's management has constantly monitored the fair value of the actuarial asset of the post-employment benefit plans due to the instability of the interest rate, which is determined based on market data. Although to the economic instability in this pandemic period, the fair value of the plan assets didn’t fall at December 31, 2020 in relation to the fair value at December 31, 2019. Therefore, the pension plan did not generate additional obligations due to the existence of a surplus, as for the actuarial liabilities of the assistance plan, an increase was recognized in an amount sufficient to cover the actuarial deficit in view of the current assessment, as shown in Note 23.

a.7) Liquidity

The Company has met its expected liquidity ratios and Management believes the financial situation and working capital are within its sufficient requirements.

At December 31, 2020, the Company's consolidated net working capital totals R$ 1,753,039 (R$ 2,563,575, at December 31, 2019) with a balance of cash and cash equivalents of R$ 3,222,768, compared to the balance of R$ 2,941,727 at December 31, 2019.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

The Company has been monitoring its financial liquidity, considering the possibility of raising funds and the prospect of cash retention, already implemented and under preparation, and taking necessary actions in our operations such as cost reduction and postponement of investments with the objective of guaranteeing compliance with financial obligations in due time.

a.8) Other assets

The Company has not identified any changes in circumstances that indicate impairment of other assets. It should be noted that the Company records changes in sectorial financial assets and liabilities, updated up to the date of the tariff adjustment/review when, the Granting Authority ratifies the transfer on the tariff base and the Company transfers it to the consumer during the next annual cycle, which at Copel occurs as of June 24 of each year. With the emergency measures for the electric power sector provided for in Provisional Act No. 950 dated April 8, 2020 and in Decree 10,350 of May 18, 2020, Management understands that realization of sector financial assets and liabilities recorded as at December 31, 2020 is sustained. On July 31, 2020, Copel DIS had already had access to the total amount of funds requested from the Covid Account.

In view of all of the above, it should be noted that there was no significant or material impact on the Company's business that could change the measurement of its assets and liabilities presented in the financial statements at December 31, 2020, and until the date of this publication. However, considering that, like all companies, Copel is exposed to risks arising from any legal and market restrictions that may be imposed, it is not possible to ensure that there will be no impact on operations or that the result will not be affected by the future consequences of the pandemic.

b) | Renegotiation of the Hydrological Risk (Generation Scaling Factor-GSF)

On September 9, 2020, Law No. 14,052 was published, which amended Law No. 13,203/2015, establishing new conditions for renegotiating the hydrological risk related to the portion of the costs incurred with the GSF, assumed by the holders of the hydroelectric plants participating in the Energy Reallocation Mechanism (MRE) since 2012, with the worsening of the water crisis.

The purpose of the legal amendment was to compensate the owners of the hydroelectric power plants participating in the MRE for non-hydrological risks caused: (i) for generation projects called structuring, related to the anticipation of the physical guarantee, (ii) for the restrictions on the start-up of transmission facilities necessary for the flow of the generation of structuring and (iii) for generation outside the order of merit and import. Said compensation will be occur upon the extension of the grant, limited to seven years, calculated based on the values of the standards applied by Aneel.

On December 1, 2020, Aneel Normative Resolution No. 895 was issued, which establishes the methodology for calculating the compensation and the procedures for renegotiating the hydrological risk. To be eligible for the compensation provided for in Law No. 14,052, holders of hydroelectric power plants participating in the MRE must: (i) abandon any lawsuits whose purpose is the exemption or mitigation of hydrological risks related to the MRE, (ii) waive any allegation and/or new actions in relation to the exemption or mitigation of the hydrological risks related to the MRE, (iii) not having renegotiated the hydrological risk.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

In the renegotiation of the hydrological risk, Management will exercise its judgment in the development and application of the accounting policy, as provided for in IAS 8 - Accounting Policies, Changes in Accounting Estimates and Errors, using the precepts of IAS 38 by analogy, in order to deal with it is essentially an intangible asset related to the concession right resulting from compensation for costs incurred in previous years. Additionally, considering also by analogy of the referred IAS 38, the asset to be constituted , in case of renegotiation of the non-hydrological risk, will be recognized at fair value, considering the best estimate of the Company, based on the parameters determined by Aneel's regulation, considering the expected future flows in this new concession period, as well as the compensation values calculated by the Electric Energy Trading Chamber (CCEE). The amount will be transformed by Aneel in extending the term of concession.

The compensation to hydroelectric generators, which will occur through the extension of the concession period for concessions of generation, will be recognized, in case of renegotiation, as intangible asset in exchange for the compensation of electricity costs.

On March 2, 2021, CCEE released the calculations of the renegotiation of the hydrological risk and the results, which total R$ 1,366,343 for the 15 eligible plants of the Company, to be sent to Aneel and submitted for approval analysis. As of the date of publication of these Financial Statements, the Company has not yet adhered to the renegotiation of the hydrological risk, as the Management awaits the approval by Aneel of the approximately 510 days of average extension of the concession of its plants to assess the possible adherence to the terms of the renegotiation, and waiver of future questioning or lawsuits in relation to the hydrological risks at issue.

2.1.1 | Compagás

Compagás is a party to a concession agreement entered into with the Concession Grantor, the State of Paraná, which determines the date of July 6, 2024 as the concession's expiration date.

On December 7, 2017, the State of Paraná published Complementary Law 205, introducing a new interpretation to the end of the concession, understanding that expiration occurred on January 20, 2019. There was an understanding among the shareholders that the law could be challenged and Compagás filed a lawsuit, considering the unconstitutionality of the Law. Provisional protection was granted to Compagás recognizing the validity of the maturity clause provided for in the contract.

In view of the above, however, there was no consensus between Copel's and Compagás' understanding of which document should be used for accounting recognition, so that Copel considered the Supplementary Law as a document for accounting purposes while the Compagás maintained its accounting records considering the expiration date provided for in the concession contract.

On December 1, 2020, Supplementary Law No. 227 was issued, revoking article 15 of Supplementary Law No. 205/17, which determined the expiration of the concession for the exploitation of gas services channeled by Compagás on January 20, 2019. Therefore, Copel reassessed the balances of Compagás' financial assets and intangible assets within its consolidated balance sheet, so that, as of December 2020, the balance of the financial assets, to be received for the indemnity provided for in the concession contract, is the same balance recorded in the balance sheet of its investee and the difference generated by the practice adjustment made since December 2017, recorded in intangible assets, will be amortized until the end of the concession.

- Cutia and Bento Miguel Wind Complexes: From the last two week of December 2018 to March 2019, all wind farms went into commercial operation, with a total installed capacity of 312.9 MW.

As of December 31, 2020, the main projects under construction are still in progress.

3 | Basis of Preparation

3.1 | Statements of compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS), issued by the International Accounting Standards Board – IASB.

The Company's Management believes that all the relevant information used in its management is evidenced in the consolidated financial statements, and that it corresponds to that used by Management in administering the Company.

The issuance of these consolidated financial statements was approved by Management on April 19,2021.

3.2 | Functional and presentation currency

The financial statements are presented in Brazilian Reais, which is the functional and presentation currency of the Company. Balances herein have been rounded to the nearest thousand, unless otherwise indicated.

3.3 | Basis of measurement

The financial statements were prepared based on the historical cost, except for certain financial instruments and investments measured at fair value, as described in the respective accounting policies and notes.

3.4 | Use of estimates and judgments

In the preparation of these financial statements, Management used judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses of the Company. Actual results may differ from those estimates.

Estimates and assumptions are reviewed on a continuous basis. Changes in estimates are recognized prospectively.

3.4.1 | Judgments

Information about judgment referring to the adoption of accounting policies which significantly impacts the amounts recognized in the consolidated financial statements, except those involving estimates, is included in the following notes:

| · | Note 4.1 - Basis of consolidation and

3.5 | Management’s judgment on going concern

Management has concluded that there are no material uncertainties that cast doubt on the Company's ability to continue as a going concern. No events or conditions were identified that, individually or in the aggregate, may raise significant doubts on its ability to continue as a going concern.

The main bases of judgment used for such conclusion are: (i) main activities resulting from long-term concessions; (ii) robust equity; (iii) strong operating cash generation, including financial capacity to settle commitments entered into with financial institutions; (iv) historical profitability; and (v) fulfillment of the objectives and targets set forth in the Company's Strategic Planning, which is approved by Management, monitored and reviewed periodically, seeking the continuity of its activities.

3.6 | Restatement of comparative balances

3.6.1 | Reclassification of the assets of the Existing System Basic Network - RBSE

After the initial adoption in 2018 of IFRS 15 and IFRS 9, the Brazilian Securities and Exchange Commission (CVM) published on December 1, 2020 complementary interpretive guidance on the adoption of these standards to be observed in the preparation of the Financial Statements of the Electricity Transmitting Companies for the Financial Statements at December 31, 2020.

F-24

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

With regard to the treatment of the assets of the Existing System Basic Network (RBSE), Technical Note No. 336/2016 of Aneel regulated the calculation method for calculating the cost of capital and calculating the Annual Permitted Revenue (RAP) regarding the value of the installations of the RBSE assets and determined payment amounts and terms for the concessionaires. The RAP calculation was divided into two components: economic, referring to the cost of capital of non-depreciated assets in July 2017, and financial, referring to the unpaid cost of capital between January 2013 and June 2017, with annual payment for an 8-year term.

Copel's interpretation, when implementing Technical Pronouncements IFRS 15 and IFRS 9, was to classify the financial portion as a financial asset at amortized cost by understanding, at the time, that: Aneel separated the receipt flows with specific contractual terms, that assets are maintained in the business model to receive contractual cash flow; and that the application of the Variable Portion (PV) would not significantly change the economic nature of the financial portion.

However, CVM's understanding, presented in Circular Letter/CVM/SNC/ SEP/No. 04/2020, is that there is the same category of RBSE asset, subject to the same regulation and the same tariff and regulation mechanism, in a way that the entire transmission infrastructure should be classified as a contract asset.

Accordingly, at December 31, 2020, Copel reclassified the balances of RBSE assets that were recorded in line item Accounts receivable linked to concession to Contract assets. Additionally, the balances of these line items, in the Balance Sheets as of December 31, 2019 and January 1, 2019, are being restated to reflect the reclassification, for comparative purposes, with no effect on the total current assets and non-current assets, in the statements of income, comprehensive income and cash flows of previous years. The reclassification also had no impact the covenants of borrowing and debenture agreements. The following tables show the effects only between the asset line items:

4 | Significant Accounting Policies

4.1 | Basis of consolidation

4.1.1 | Calculation of equity in earnings of investees

Investments in joint ventures and associate are recognized in the consolidated financial statements based on the equity method. Under this method, investments are initially recorded at cost and their carrying amount is increased or decreased by the recognition of the investor's interest in profit, loss and other comprehensive income generated by investees after acquisition. This method must be discontinued from the date the investment ceases to qualify as a jointly controlled or associated company.

Payment of dividends decreases the carrying value of investments.

When required, for calculation of equity in earnings of investees, the investees' financial statements are adjusted to align their policies with the Company's accounting policies.

4.1.2 | Subsidiaries

The subsidiaries are entities to which the Company is exposed to or has a right over the variable returns arising from its involvement with them and has the ability to affect those returns exerting its power over the entities.

The financial statements of the subsidiaries are included in the consolidated financial statements as from the date they start to be controlled by the Company until the date such control ceases.

The balances of the subsidiaries’ assets and liabilities, and profit or loss, are consolidated and transactions between consolidated companies are eliminated. The balances of transactions between continuing operations and discontinued operations are also fully eliminated in the consolidated balance sheet.

4.1.3 | Noncontrolling interests

Noncontrolling interests are presented in equity, separately from the equity attributable to the Company's shareholders. Profits, losses and other comprehensive income are also allocated separately from the ones allocated to the Company's shareholders, even if this procedure results in negative noncontrolling interest balance.

4.1.4 | Joint ventures and associates

Joint ventures are entities over which the Company, subject to an agreement, has the ability to affect returns exerting its power in conjunction with other parties, irrespective of the percentage of interest in the voting capital.

Associates are entities over which the Company exerts significant influence regarding financial and operational decisions, without control.

When the share in losses of a joint venture or associate equals or exceeds the accounting balance of the investor’s equity interest in the investee, the investor should discontinue the recognition of its share in future losses. Additional losses will be considered, and a liability will be recognized, only if the investor incurs legal or constructive obligations, or performs payments on behalf of the investee. Should the investee subsequently post profits, the investor should resume the recognition of its interest in these profits only subsequent to the point at which the portion to which it is entitled to in these subsequent profits equals its share in unrecognized losses.

4.1.5 | Joint operations (consortiums)

Joint operation is a joint business according to which parties that jointly control the business have rights on assets and obligations regarding liabilities related to the business.

Joint operations are recorded in proportion to the share of interest held in their assets, liabilities and profit or loss.

4.1.6 | Business combination

The acquisition analysis is done on a case-by-case basis to determine whether the transaction represents a business combination or an asset purchase. Transactions between companies under common control do not constitute a business combination.

Assets and liabilities acquired in a business combination are accounted for using the acquisition method and are recognized at their fair value at the acquisition date.

The excess of the acquisition cost over the fair value of the net assets acquired (identifiable assets acquired, net of assumed liabilities) is recognized as goodwill in intangible assets. When the amount generated is negative, the bargain purchase gain is recognized directly in profit or loss.

The amount paid that refers specifically to the concession right acquired in a business combination where the acquired entity is a concession operator, whose right to the concession has a known and defined term, is not characterized as goodwill.

In acquisitions of interests in affiliates and in joint ventures, although they do not constitute a business combination, the net assets acquired are also recognized at fair value. Goodwill is presented in the investment.

4.2 | Financial Instruments

Financial instruments are recognized immediately on the trade date, that is, when the obligation or right arises. They are initially recorded at fair value, unless it is a trade receivable without a significant financing component, plus, for an item not measured at fair value through profit or loss, any directly attributable transaction costs. An accounts receivable from customers without a significant component of financing is initially measured at the price of the transaction.

Fair values ​​are determined based on market prices for financial instruments with active market, and by the present value method of expected cash flows, for those that have no quotation available in the market.

The Company does not have financial instruments measured at fair value through other comprehensive income. The Company operates with derivative financial instruments as described in Note 4.15.

Financial assets are not reclassified subsequent to initial recognition, unless the Company changes the business model for the management of financial assets, in which case all affected financial assets are reclassified on the first day of the reporting period subsequent to the change in business model.

The Company's financial instruments are classified and measured as described below.

4.2.1 | Financial assets recorded at fair value through profit or loss

Financial assets recorded at fair value through profit or loss include assets classified as held for trading, financial assets designated upon initial recognition as at fair value through profit or loss or financial assets required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of being sold or repurchased in the near term. Financial assets with cash flows that are not solely payments of principal and interest are classified and measured at fair value through profit or loss, irrespective of the business model. After initial recognition, transaction costs and attributable interest expenses, when incurred, are recognized through profit or loss.

4.2.2 | Financial assets measured at amortized cost

These are so classified and measured when: (i) the financial asset is maintained within a business model whose objective is to maintain financial assets in order to receive contractual cash flows; and (ii) the contractual terms of the financial asset give rise, on specified dates, to cash flows that exclusively comprise payments of principal and interest on the principal amount outstanding.

4.2.3 | Financial liabilities measured at amortized cost

Financial liabilities are measured at amortized cost using the effective interest method. This method is also used to allocate interest expense of these liabilities for the period. The effective interest rate is the rate that discounts estimated future cash flows (including fees paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) over the expected life of the financial liability or, when appropriate, over a shorter period, for the initial recognition of the net carrying amount.

4.2.4 | Financial liabilities measured at fair value through Profit or Loss

These are liabilities designated upon initial recognition as at fair value through profit or loss and those classified as held for trading. Financial liabilities designated fair value through profit or loss are stated at fair value with the respective gains or losses in fair value recognized in the statement of income. Net gains or losses recognized in profit or loss include the interest paid on the financial liability.

4.2.5 | Derecognition of financial assets and liabilities

The Company derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which the Company neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.

The Company derecognizes financial liabilities only when its obligations are discharged, cancelled or settled. The difference between the carrying amount of the derecognized financial liability and the corresponding disbursement made, or to be made, is recorded to profit or loss.

4.3 | Net sectorial financial assets and liabilities

According to the amendment to the concession agreement of distribution companies, the Company records changes in sectorial financial assets and liabilities, until the next tariff adjustment/review process, when the Concession Grantor approves the transfer as components of the power tariff and thus, it passes the adjustment on to consumers in the next tariff cycle, which occurs on June 24 of each year.

The balances of the net sectorial financial assets and liabilities comprise: a) Parcel A Variation Compensation Account - CVA, which records the variation between estimated and actual energy purchase and transmission costs and sector charges, and b) financial items, which correspond to energy over-contracting, neutrality of charges and other rights and obligations included in the tariff.

After approval of the Annual Tariff Adjustment and Periodic Tariff Review, the new tariff applied for the tariff year provides for the collection or return of the constituted assets and liabilities.

In the event of termination of the concession for any reason, the residual values of Part A items and other financial components not recovered or returned through tariff are incorporated in the calculation of compensation or deducted from unamortized assets indemnity values, thus protecting rights or obligations of the distribution company to the Concession Grantor.

4.4 | Accounts receivable related to the concession

Refer to financial assets of the concessions with unconditional right to receive cash by the Company, guaranteed by the Concession Grantor by contractual clause and specific legislation.

4.4.1 | Power distribution service concession

The concession agreement for electricity distribution provides that the users of the public service remunerate part of the investments made by the concessionaire and the Concession Grantor at the end of the concession indemnifies the other party. This model provides for the recognition of financial assets, contract assets in the construction period and intangible assets.

The portion recognized as financial asset refers to the indemnity set forth in the public power distribution service concession agreements, which the Company understands as an unconditional right to cash payments from the Concession Grantor upon expiration of the concession. This indemnification aims to reimburse the Company for investments made in infrastructure, without recovery, through the tariff.

The cash flows related to these assets are determined taking into account the Regulatory Compensation Basis (Base de Remuneração Regulatória or BRR), defined by the Concession Grantor, and the fair value is recorded based on the replacement cost methodology of the assets included in the distribution infrastructure linked to the concession.

4.4.2 | Piped gas distribution service concession

Gas concession agreement follows the bifurcated model, whereby part of the investments made by the concession operator is paid by users of the public service and the other part is indemnified by the Concession Grantor, the State of Paraná, at the end of the concession. This model provides for recognition of a financial asset, a contract asset in the construction period and an intangible asset.

The amount recognized as a financial asset is the amount that will be indemnified by the Concession Grantor corresponding to the investments made in the last ten years prior to the end of the concession as foreseen in the agreement and that, according to Management, assures the unconditional right to receive cash at the end of the concession. The indemnity assumption is based on the replacement cost of the concession assets.

4.4.3 | Bonus for the grant of quota system generation concession agreement

The quota system generation concession agreement provides for the payment of a bonus for the grant to the Concession Grantor, pursuant to paragraph 7 of article 8 of Law 12,783/2013.

This bonus is recognized as a financial asset because it represents an unconditional right to receive cash, guaranteed by the Concession Grantor during the term of the concession and without risk of demand.

The remuneration of this financial asset is based on the Weighted Average Cost of Capital - WACC defined by the National Energy Policy Council (CNPE) in Resolution 2/2015, which is being presented in the statement of income as operating revenue in accordance with the Company's business model.

4.4.4 | Concession of power generation

The Company has operated and operates concession agreements for power generation that contain indemnification clauses for the infrastructure not depreciated, amortized and/or received during the concession term. After maturity, the residual balance of the assets is transferred to Accounts receivable related to the concession. At the end of each reporting period, Management evaluates the recoverability of the asset, remeasuring its cash flow based on its best estimate.

4.5 | Contract assets

Represented by the construction in progress or in service of the infrastructure delegated by the Concession Grantor, conditional upon the receipt of revenue not only by the passage of time, but after fulfilling the performance obligation to maintain and operate the infrastructure.

4.5.1 | Power distribution service concession

Represents the concessionaire's contractual right related to the works under construction to meet the needs of the concession, accounted for at cost plus financial charges, when applicable.

When the assets are put into operation, the assets are transferred to the intangible asset, in the amount equivalent to what will be remunerated by the user through payment of the fee for the use of the services, or to the accounts receivable associated to the concession, in the amount equivalent to the residual portion of the assets not amortized, which will be reverted to the Concession Grantor through indemnification at the end of the concession.

4.5.2 | Power gas distribution service concession

Construction in progress for the distribution of piped gas which will be transferred to intangible assets upon their entry in operation and to the extent that the right (authorization) is received to charge the users of the public service. The amount that will not be amortized within the term of the concession is presented in financial assets, indemnified at the end of the concession by the Concession Grantor according to contractual definition.

4.5.3 | Power transmission concession

Represents the balance of public electricity transmission contracts signed with the Concession Grantor to build, operate and maintain the high voltage lines and substations of the generation centers up to the distribution points.

During the term of the concession agreement, the Company receives, subject to its performance, a remuneration denominated Annual Revenue Allowance (RAP) that remunerates the investments made in the construction of the infrastructure and covers also, the costs of operation and maintenance incurred.

After the beginning of the commercial operation and insofar as the operation and maintenance service - O&M is provided, the portion of RAP referring to O&M revenue is recognized in profit or loss at fair value, on a monthly basis, and billed together with the revenue part recognized in the construction phase, referring to the remuneration of the built-up assets. This amount billed after complying with the O&M performance is reclassified to the financial asset under Customers until its effective receipt.

The Company estimates its revenue in the construction phase at fair value based on the budgeted cost of the work and used by management as a parameter for bidding on the concession auction. Fair value revenue comprises the budgeted cost for the entire construction period plus the construction margin, which represents sufficient profit to cover the costs of managing and monitoring the work.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

The remuneration rate of each concession is determined by the projection of the expected cost, of the profit margin on the cost in the construction phase and also of the projection of the RAP to be received in the operational stage, already net of the variable consideration estimate (PV) and the RAP part of the O&M performance. This fair value valuation technique using the income approach discounts cash flow for the entire concession period, determining at initial recognition the implied rate that zeroes the flow over time. This remuneration rate is fixed at the initial period and does not change during the performance of the contract and represents the market rate in effect at the time under the conditions of the negotiation between parties.

The assets arising from the construction of the transmission infrastructure are formed by the recognition of construction revenue, according to the percentage of completion of the construction (Note 4.13), and by their financial remuneration (Note 4.12.2).

The Company recognizes gains and losses due to efficiency or inefficiency in the construction of the infrastructure and due to periodic tariff review (RTP), when incurred, directly in the statement of income for the year.

Upon expiration of the concession, any uncollected amounts related to the construction of infrastructure shall be received directly from the Concession Grantor, as an unconditional right to cash reimbursement pursuant to the concession agreement, as compensation for investments made and not recovered through tariffs (RAP).

The assets that compose the Existing System Basic Network - RBSE include one economic tariff component, referring to the cost of capital of the assets not depreciated in July 2017, and one financial tariff component , resulting from the right for the Annual Permitted Revenue (RAP) of the Concession Agreement No. 060/2001, not received in the period from January 2013 to June 2017, plus monetary adjustment and remuneration interest.

4.6 | Accounts payable related to the concession

These refer to the amounts set forth in the concession agreement in connection with the right to explore hydraulic power generation potential (onerous concession), whose agreement is signed as Use of Public Property (Uso do Bem Público or UBP) agreements. The obligation is recognized on the date of signature of the concession agreement corresponding to the present value of future cash payments for the concession. The liability is then remeasured using the effective interest rate and reduced by contractual payments.

4.7 | Inventories (including property, plant and equipment and contract assets)

Materials and supplies in inventory, classified under current assets, and those assigned for investments, classified under property, plant and equipment, and contract assets, have been recorded at their average acquisition cost. Recorded amounts do not exceed their net realizable value.

4.8 | Property, Plant and Equipment

The property, plant and equipment related to the public service concession agreement are depreciated according to the straight-line method based on annual rates set forth and reviewed periodically by ANEEL, which are used and accepted by the market as representative of the economic useful lives of the assets related to concession's infrastructure. Property, plant and equipment related to contracts for the use of public property under the independent electricity producer scheme are depreciated based on annual rates established by ANEEL limited to the concession period. All other property, plant and equipment are depreciated using the straight-line method based on estimates of their useful lives, which is reviewed annually and adjusted if necessary.

Costs directly attributable to construction works as well as interest and financial charges on borrowings from third parties during construction are recorded under property, plant and equipment in progress, if it is probable that they will result in future economic benefits for the Company.

4.9 | Intangible Assets

These comprise software acquired from third parties and software developed in-house and are measured at acquisition cost and amortized over five years, besides Intangible assets from Concession Agreements below.

4.9.1 | Onerous concession of electric power generation

Corresponds to acquisition of exploration rights on hydropower potential whose onerous concession contract is signed as Use of Public Property - UBP.

During construction work, this asset is recognized at the present value of future cash disbursements during the Concession Agreement term. When commercial operation starts, the amount starts to be amortized over the concession period.

4.9.2 | Hydrological risk renegotiation (Generation Scaling Factor - GSF)

Asset consisting of the renegotiation of the hydrological risk under the terms of Law No. 13,203/2015 and subsequent changes, arising from the amounts recovered from the cost with the adjustment of the Energy Reallocation Mechanism - MRE (GSF). The amount was transformed by ANEEL into an extension of the concession period, which is amortized on a straight-line basis until the end of the new concession period, according to note 14.1.

4.9.3 | Power distribution service concession

This comprises the right to control infrastructure, built or acquired as part of the electric energy public service concession, and the right to charge fees to the users of the public service.

Intangible assets are recorded at their fair acquisition and construction value, less accumulated amortization and impairment losses, when applicable. The amortization of intangible assets reflects the pattern in which it is expected that future economic benefits will flow to the Company during the concession period.

During the infrastructure construction phase costs are classified as contract assets (Note 4.5).

4.9.4 | Piped gas distribution service concession

Intangible assets for piped gas distribution services, which correspond to the right to charge users for the gas supply.

This intangible asset was initially recognized at acquisition or construction cost, plus interest and other capitalized finance charges. This asset is amortized using the straight-line basis over its estimated useful life, considering the economic benefits generated by intangible assets.

During the infrastructure construction phase, costs are classified as contract assets (Note 4.5).

4.9.5 | Intangible assets acquired separately

Intangible assets with a finite useful life, acquired separately, are recorded at cost, less accumulated amortization and accumulated impairment losses. Amortization is recognized using the straight-line method based on the estimated useful lives of the corresponding assets. The estimated useful lives and the amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for on a prospective basis.

4.9.6 | Derecognition of intangible assets

An intangible asset is derecognized when no future economic benefits are expected from use or disposal. Gains or losses arising from disposal of an intangible asset are recognized in profit or loss, measured as the difference between net disposal proceeds and the carrying amount of the asset.

4.10 | Impairment of assets

Assets are assessed to detect evidence of impairment.

4.10.1 | Financial assets

Provisions for losses on financial assets are based on assumptions about default risk, existing market conditions and future estimates at the end of each year.

The Company applies the simplified approach of IFRS 9 to the measurement of expected credit losses for the entire existence of financial assets that do not have significant financing components, by considering a provision for expected loss over a useful life for all trade accounts receivable. To measure expected credit losses, trade accounts receivable is grouped based on shared credit risk characteristics, numbers of days late, in the amount considered enough to cover losses on the realization of these assets, based on specific criteria of the payment history, collection actions carried out for the credit recovery and relevance of the amount due in the receivables portfolio.

4.10.2 | Non-financial assets

Assets under formation arising from onerous concession and concession rights and/or authorization to generate electricity are classified as intangible assets. Impairment is tested along with the other assets of that cash-generating unit.

F-38

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

Whenever there is a loss resulting from situations where an asset’s carrying value exceeds its recoverable value, defined as the higher of the asset’s value in use or its net selling price, this loss is recognized in profit or loss for the year.

For impairment testing purposes, assets are grouped at the lowest levels for which there are separately identifiable cash flows (Cash Generating Units - CGU).

The amount of the impairment of non-financial assets is reviewed at the reporting date. In case of reversal of impairment losses which had been recorded in prior years, this reversal is recognized in current year's profit or loss.

The Impairment of contract assets in their construction phase are tested immediately, mainly considering the use of the effective interest rate fixed at the beginning of the project and carried to the end of the concession cash flow. After the beginning of the commercial operation, the portion of revenue recognized is tested for impairment in the accounts receivable from customers. For the receivable part conditioned to fulfill the performance obligation to maintain and operate the infrastructure, the Company has no history and no expectation of losses, since amount are subject to guarantee structures, via shared apportionment of eventual default losses among the other members of the national interconnected system managed by the “Operador Nacional do Sistema” (ONS) and by jurisdiction of the sector.

4.11 | Provisions

Provisions are recognized when: i) the Company has a present obligation (legal, formalized or non-formalized) resulting from a past event, ii) it is probable (i.e., more likely than not) that an outflow of resources embodying economic benefits will be required to settle the obligation, and iii) a reliable estimate can be made of the amount to settle the obligation.

The estimates of outcomes and financial impacts are determined by the Company, which requires use of judgment by Management, supplemented by the experience of similar past transactions and, in some cases, by independent expert reports.

Environmental liabilities are recognized as the Company assumes formal obligations before regulatory agencies or becomes aware of potential risks related to environmental issues, which may lead to cash disbursements that are deemed probable and that may be estimated. During the project implementation phase, the accrued amounts are included in property, plant and equipment (generation), construction cost (transmission) or contract assets (distribution). At the start of operations, all costs included in the Operating License, whose programs will be executed during the concession and the respective disbursement has not yet occurred, are measured and adjusted to present value according to the estimated cash flow of disbursements and recorded as environmental provisions matched against the assets related to the project, being adjusted periodically.

Once the project enters commercial operation, all costs or expenses incurred with environmental programs related to the project’s operation and maintenance licenses are analyzed according to their nature and included in profit or loss for the period.

4.12 | Revenue recognition

4.12.1 | Revenue from contracts with customers

Revenue is measured based on the consideration that the Company expects to receive in a contract with the customer, net of any variable consideration. The Company recognizes revenues when it transfers control of the product or service to the customer and when it is probable to receive the consideration considering the client's ability and intention to pay the consideration when due. The Company's operating revenue comes mainly from the electricity supply and from the electric network availability.

The revenue from electricity supply is recognized monthly based on the data for billing that are determined by the average MW of contracted electricity and declared with the CCEE. When the information is not available, the Company estimates the revenue considering the contracts’ rules, the price estimate and the volume provided.

For wind power generation companies subject to minimum generation amounts, the Company understands that it is subject to variable consideration, and for this reason, includes a provision for non-performance based on the annual generation estimates, reducing revenue.

Revenue from electric power supply and network availability is recognized monthly based on measured and effectively billed energy. In addition, the Company records unbilled revenue, calculated from the period between the last billing and the end of each month, by estimate based on the last measurement taken. In the concession contract for the public electricity distribution service, non-performance compensations are provided for quality indicators that, when incurred, reduce electricity availability revenue.

4.12.2 | Interest income

Interest income is recognized when it is probable that future economic benefits will flow to the Company and its amount can be reliably measured. Interest income is recognized on a straight-line basis and based on time and the effective interest rate on outstanding principal amounts. The effective interest rate is the one that discounts the estimated future cash receipts calculated during the estimated life of the financial asset in relation to initial net carrying amount of that asset.

Regarding the contract assets of the power transmission concession, financial compensation revenue is recognized using the implicit remuneration rate established at the beginning of each project, which is presented in the statement of income as operating income in accordance with the Company's business model.

4.13 | Construction revenues and costs

Revenue related to construction services for infrastructure in the power transmission and distribution services, and gas distribution, are recognized over time based on the stage of completion of the work.

Related costs are recognized in the statement of income as construction cost.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

Given that Copel DIS and Compagás outsource the construction of distribution infrastructure to unrelated parties through works carried out in the short term, the construction margin to the power and gas distribution activities result in no significant amounts, resulting in the non-recognition of such margin.

The construction margin adopted for the transmission activity for the years 2020, 2019 and 2018 was 1.65%, and results from a calculation methodology which considers the respective business risk.

4.14 | Power purchase and sale transactions in the Spot Market (Electric Energy Trading Chamber - CCEE

Power purchase and sale transactions in CCEE are recorded on the accrual basis of accounting, based on data released by CCEE, which are calculated by the product of the Differences settlement prices - PLD multiplied by the energy surplus declared with CCEE, or, when such information is not available in a timely manner, by an estimate prepared by Management.

4.15 | Derivative Financial Instruments

4.15.1 | Power purchase and sale transactions

The Company negotiates energy purchase and sale agreements and part of its contracts are designated and classified as derivative financial instruments measured at fair value through profit or loss.

Unrealized net gains or losses arising from the mark-to-market of these contracts (the difference between contractual and market prices) are recognized in the statement of income.

4.15.2 | Non-Deliverable Forward (NDF) contracts

The Company operates with Non-Deliverable Forward – NDF contracts, which aim exclusively at providing hedge against exchange rate risks associated with cash flows from capital contributions to subsidiaries, when they reflect foreign-currency denominated purchases of projected equipment. They are measured at their fair value, with changes recorded in the statement of income for the year. The fair value is calculated based on the information of each contracted operation and the respective market information on the closing dates of the financial statements.

4.16 | Taxes

4.16.1 | Income Tax and Social Contribution

The taxation on profit comprises income tax and social contribution calculated based on the taxable profits (adjusted profit) of each taxable entity at the applicable tax rates according to prevailing legislation, namely, at 15%, plus 10% surtax on the amount exceeding R$ 240 per year, for income tax and at 9% for social contribution.

Income tax and social contribution losses can be offset against future taxable profits, considering the limit of 30% of the taxable profit for the period, and can be carried forward indefinitely.

4.16.2 | Deferred income tax and social contribution

The Company, based on its profitability history and the expectation of generating future taxable profits, based on its internal projections prepared for reasonable periods for its business, sets up a deferred tax asset on temporary differences between the tax bases and on tax losses and negative tax basis.

F-41

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

The deferred income tax and social contribution are recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used for tax calculation purposes, to the extent that it is probable that there will be sufficient taxable profits against which the temporary differences can be utilized and the tax losses can be offset.

Deferred tax assets and liabilities may be offset if there is a legal right to offset the current tax assets and liabilities and they relate to the same taxing authority.

4.16.3 | Other taxes recoverable and other tax obligations

Sales and services revenues are subject to value-added tax (Imposto sobre Circulação de Mercadorias e Serviços or ICMS) and service tax (Imposto sobre Serviços or ISS), at the applicable rates, and to the PIS (Social Integration Program) and COFINS (Contribution for Social Security Funding).

Credits resulting from non-cumulative PIS and COFINS charges are accounted for as reductions to operating costs in the statement of income.

Credits arising from non-cumulative ICMS, PIS and COFINS related to the purchase of assets are presented as reductions to the acquisition cost of these assets.

Prepayments or amounts that can be offset are presented in current and non-current assets, according to their expected realization.

4.17 | Post-employment benefits

The Company and its subsidiaries sponsor pension plans to supplement retirement and pension plans and the Assistance Plan (medical and dental assistance) for their active employees and their legal dependents. The amounts of these actuarial commitments (contributions, costs, liabilities and/or assets) are calculated annually by an independent actuary, with the base date that coincides with the end of the year. The economic and financial assumptions for the purposes of the actuarial valuation are discussed with the independent actuary and approved by the Parent Company’s Management.

The assets of the benefit plans are valued at market value (marked-to-market). The value of the net plan liability is recognized at the present value of the actuarial obligation, less the fair value of the plan assets. The adoption of the projected credit unit method adds each year of service as a triggering event for an additional benefit unit, adding up to the calculation of the final obligation.

Other actuarial assumptions are used, which take into account biometric and economic tables in addition to historical data from the benefits plans, obtained from the manager of these plans, Fundação Copel de Previdência e Assistência Social.

Actuarial gains or losses caused by changes in assumptions and/or actuarial adjustments are recognized in other comprehensive income.

4.18 | Leases

Leases are recognized at present value as a right-of-use asset and lease liability and, from the initial registration, the amortization of the asset and interest on the liability are accounted for separately in profit or loss. The Company adopts exemptions from recognition provided for short-term leases (lease term of up to 12 months) and leases of low value assets, so that these contracts are recognized as operating costs and / or operating expenses on a straight-line basis during the term of the contract.

In addition, the Company has land lease agreements for the development of wind power generation projects that provide for minimum payment during the study/construction period and payment based on variable remuneration during the period of commercial operation. For contracts that are subject to minimum payment, the Company recognized right-of-use assets and lease liabilities. While for contracts that are in commercial operation, the amounts are recorded in the income statement, in operating costs and / or expenses, when the event or condition is satisfied.

To define the interest rate, the cost of the last fundraising carried out via debentures is considered, disregarding incentivized or subsidized funding, considering that this is the way the Company is used to finance cash flow.

4.19 | Standards applicable to the Company effective January 1, 2020

From January 1, 2020, changes in the following pronouncements are in effect, without significant impacts on the Company's financial statements:

7.2 | Electricity Trading Chamber - CCEE

Balance receivable deriving from the positive position in the monthly settlement of the spot market centralized by CCEE. Amounts are received in the second month following the recognition of revenue or offset against future settlements when the result is negative for the subsidiary.

Of the total presented, R$119,665 refer to the controversial portion resulting from the effects of the injunction for exclusion of responsibility of Colíder HPP. As a result of unforeseeable circumstances and force majeure, the power plant had its commercial start-up delayed, which was initially scheduled for January 2015. The Company is contesting in court, filing a request for exclusion of liability so that the mandatory supply of energy contracted by the plant, in the period in delay, is postponed. Expected credit losses were recorded in the same amount as the receivable balance, as presented in Note 7.3 .

Copel GeT filed an administrative request for the exclusion of liability at ANEEL, which was denied, and subsequently, at 12.18.2017, it filed an ordinary lawsuit with request for advance protection with the Court, requesting the reversal of the agency's decision. On April 6, 2018, the Federal Court of the 1st Region fully granted the preliminary injunction applied for in the interlocutory appeal to suspend the enforcement of any burden or penalty to Copel as a result of noncompliance with the deadlines originally provided for in the Concession Agreement until a final unappelable ruling is rendered. The main action is pending judgment on merits.

The contracted energy of the plant is 125 MW mean. For overdue periods the contract was fulfilled as described below:

- From January 2015 to May 2016, with suspension of energy delivery by operation because of the injunction obtained by Management;

- In June 2016, with partial reduction through a bilateral agreement and suspended remaining balance due to the court injunction;

- From July 2016 to December 2018, with reduction of all supply contracts of the CCEARs - Energy Trading Agreement in the Regulated Environment, through a bilateral agreement and participation in the New Energy and Decrease Clearing Facility ("Mecanismo de Compensação de Sobras e Déficits de Energia Nova - MCSD-EN"); and

- From January to March 2019, the firmed contracts in the regulated environment became effective again, however, energy supply continued suspended, in light of the injunction obtained. As of March 9, 2019, the plant started commercial production of its first generating unit.

Due to the fact it is awaiting a decision on the merits of the lawsuit, in the period in delay of the plant, the Company recognized in the income for the years revenue limited to the financial covenants of the agreement and the regulatory rules, as well as the cost of energy to cover the contractual guarantee.

On January 5, 2016, Copel GeT entered into a 30-year concession agreement of HPP GPS, in accordance with Law No. 12,783/2013, with payment of the Bonus from the Grant - BO to the Concession Grantor, amounting to R$ 574,827, as per ANEEL Invitation to Bid 12/2015.

The electric energy in 2016 was fully sold to the Regulated Contracting Environment - ACR under the Assured Power Quota System - CGF or “quota regime” and, as from 2017 to the end of the concession, in the proportion of 70% of the power in the ACR and 30% in the free environment - ACL.

The amount of the bonus for the grant was recognized as a financial asset due to the Copel GeT’s unconditional right to receive the amount paid with inflation adjustment based on IPCA and interest during the concession period.

Copel GeT depreciated the plants until 2015, the expiration date of the concessions, and the remaining balances were reclassified to accounts receivable linked to the concession. Although the Granting Authority has not yet disclosed the form of payment of remuneration of the assets, Management's expectation about indemnification for these assets indicates the recoverability of the recorded balance, based on the remuneration methodology established by ANEEL.

Copel GeT timely manifested to ANEEL its interest in receiving the indemnifiable amount. Formalization of proof of realization of the respective investments to ANEEL occurred on December 17, 2015. To prepare the information, the new replacement value methodology was used, as defined by ANEEL Normative Resolution No. 596/2013.

On June 30, 2020, Aneel published Homologatory Resolution 2,715, in which it ratified the result of the periodic review of the RAP of contract No. 060/2001 and on July 14, 2020 it issued Homologatory Resolution 2,725, which establishes the RAP for making available the facilities under the responsibility of the Company. In the process of the first tariff review of contract No. 060/2001, referring to the tariff cycles of 2018/2023 and which takes place every five years, operating costs, the cost of capital (WACC) and the remuneration base were reassessed, which resulted in a 10.16% RAP repositioning rate in relation to the previous cycle.

Additionally, in relation to RBSE assets, Ratifying Resolution No. 2,715 set the tariff repositioning and included the “remuneration” in the portion of RAP, which had previously been provisionally excluded due to a judicial decision now overturned. Such amounts will be received from the fourth tariff cycle started in July 2020 until June 2025, including the addition of amounts not timely received due to the provisional effects of the injunction, which will be added in the next three RAP cycles beginning in July 2020 until June 2023. The impact of the tariff review on RBSE assets totaled R$ 122,027, recorded in 2020 operating revenue.

13.1.1 | Projection for realization of deferred income tax and social contribution:

The projection of deferred tax credits realization recorded in noncurrent assets and liabilities is based on the realization period of each item of deferred assets and liabilities and tax losses, also based on projections of future results.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

The criteria used for the realization of each item are related to the predictability of realization of the main value that gave rise to the temporary difference. When the expectation of realization of the item is difficult to predict, mainly because it is not under the control of the Company, such as provisions for litigation, the Company adopts history of realization to project its future realization. The realization of the amounts of income tax and social contribution losses follow the potential compensation considering future profits and the limit defined by the legislation.

Following are the items that were the basis for the setup of the main credits, as well as their form of realization:

- Provisions for post-employment benefits: realized as the payments are made to the Copel Foundation or reversed according to new actuarial estimates;

- Provisions for legal claims: realized according to court decisions or by the reversal when the possible risk of the shares is reviewed;

- Impairment of assets: realized through the amortization and/or depreciation of the impaired asset;

- Provision for purchase of energy and charges of the main distribution and transmission grid: realized upon the effective obligation of the amounts provisioned or by the reversal of the provision;

- Provisions for R&D and PEE: realized through the expenses incurred in the projects carried out;

- Deemed cost: realized through the amortization and/or depreciation of the valued asset;

- Amounts related to the concession agreement: realized over the term of the agreement;

- Amounts related to tax losses and negative tax basis: recovered by offsetting against future taxable income;

- Other amounts: realized when they meet the deductibility criteria provided for in tax legislation, or upon reversal of the recorded amounts.

The projected realization of the deferred taxes is shown below:

| Assets | Liabilities
2021 | 618,750 | (108,316)
2022 | 223,243 | (94,626)

13.2.1 | Pis/Pasep and Cofins credit on ICMS

On August 12, 2009, Copel DIS filed for writ of mandamus No. 5032406-35.2013.404.7000 with the 3rd Federal Court of Curitiba applying for the granting of an order to stop including ICMS in the PIS and COFINS tax base, as well as to authorize it to proceed with the administrative offsetting of the amounts collected more than due for such social contributions in the last five years.

On June 16, 2020, a final unappealable ruling was handed down by the 2nd Panel of the Federal Regional Court of the 4th Region recognizing Copel DIS's right to exclude from the PIS and COFINS tax base the full amount of ICMS included in the energy supply and distribution invoices. The ruling also recognized that the limitation period, in this case, is of five years and that, therefore, Copel has the right to recover the amounts that have been paid during the five years preceding the filing of the writ of mandamus until the date of the final unappealable ruling.

Considering the final and unappealable ruling, with a favorable decision for the company, the entry of economic benefits became probable and, therefore, the asset became realizable. In view of these, Copel DIS recognized the updated tax credit in assets, which will be recovered using the following expedients: by offsetting against taxes payable within the 5-year statute of limitations period, and, if necessary, by receiving securities issued in connection with Federal Government debts (“precatórios”).

Additionally, with the assistance of the opinion of its legal counsel, the Company concluded to record the liability to be refunded to consumers for the last 10 years of the credit, as from the date of the unappealable ruling, considering the current legislation, the statute of limitations period defined in the civil code and the jurisprudence of the courts. The refund of PIS and Cofins credits to consumers awaits the conclusion of discussions with Aneel regarding compensation mechanisms and criteria, based on the effective compensation of tax credits, which currently are under analysis by the Federal Revenue of Brazil

On February 9, 2021, Aneel held a public consultation aimed at discussing how to return tax credits to consumers, as described in Note 29.2. Aneel's proposal, which is being discussed, provides for the return of the amounts through a rebate in the next tariff adjustments, within a period of up to five years. Aneel did not comment on the statutory period for returning credit to the consumer.

Also, in relation to the potential future impacts of the adjustment of the effects, to be judged by the STF under RE No. 574,706/PR, the understanding of the Company, based on the opinion of its legal advisors, is that it is highly likely that the final decisions to the benefit of the taxpayers be maintained.

The table below shows the impacts of these records on Copel's balance sheet and statement of income:

The amounts of Pis and Cofins of Copel DIS for the months of March to June 2020, which have not yet been paid when the action was concluded were remeasured with the effects from the court decision and reclassified to the liability account to be refunded to consumers.The table below shows, therefore, the total balance to be returned to consumers recorded in balance sheet:

Pis and Cofins to be refunded to consumers | 12.31.2020
Calculated until February 2020 | 3,805,985
Calculated from March to June 2020 | 121,838
| 3,927,823
Current | 121,838
Noncurrent | 3,805,985

The balance also contains the final and unappealable decision of the lawsuit records in which Compagás discussed the exclusion of ICMS from the PIS/Pasep and Cofins calculation basis. Due to this favorable ruling, Compagás recorded, on September 2019, the credit right of R$ 107,453 under Other Taxes Recoverable with corresponding entry of R$ 100,931 in operating revenue and R$ 6,522 in financial income. Part of these credits has already been recovered in 2020, so that the adjusted balance at December 31, 2020 is R$ 83,716.

13.2.2 | Pis and Cofins under suspended enforceability

On May 15, 2020, Copel Telecomunicações S.A. obtained a preliminary injunction favorable to the Company, suspending enforceability of a portion of Pis and Cofins, recognizing that ICMS should not be included in the tax base of these contributions. Accordingly, the Company has been suspending the payment of this complementary amount and provisioning the amounts until a final decision on the merits of the action is rendered. The balances of this liability, in the amount of R$2,965, are recorded in the Liabilities line associated with assets classified as held for sale.

17 | Property, Plant and Equipment

The Company records assets used in administrative and commercial facilities for generation of electric power and telecommunication services in property, plant and equipment account. Investments in electric power transmission and distribution and in piped gas distribution are recorded in contract assets, financial assets and/or intangible assets accounts as per IAS 38, IFRS 15 and IFRIC 12. (Notes 4.4, 4.5 and 4.9).

Upon initial adoption of IFRS, property, plant and equipment were measured at fair value with recognition of their deemed cost.

Under the regulation relating to the concession of public electric energy services, the assets and facilities used mostly in the generation of power are attached to these services and cannot be withdrawn, sold, assigned, or mortgaged without the prior written consent of the regulatory agency. ANEEL Resolution No. 691/2015, however, regulates the release of assets from the concessions of the Public Electric Power Service, granting prior authorization to release the property and other fixed assets not usable by the concession when they are destined for sale, and also determining that the sales proceeds less respective charges be deposited in a restricted bank account to be invested in the concession.

17.5 | Impairment of generation segment assets

Cash-generating units of the generation segment were tested for impairment based on previous evidence of impairment, assumptions representing the best estimates of the Company's management, the methodology provided for in Technical Pronouncement IAS 36 and measurement of value in use.

The calculation of the value in use was based on discounted operating cash flows over the time of concessions, maintaining the Company’s current commercial conditions. The rate used to discount the cash flows was set considering the WACC (Weighted Average Cost of Capital) methodology and CAPM (Capital Asset Pricing Model) methodology for the generation business, considering usual market parameters.

Internal references such as the budget approved by the Company, historical or past data, updating of the timeframe of work and amount of investments for projects in course support the design of key assumptions by Company Management. In the same framework, external references such as level of consumption of electric power and the availability of water resources support the key information about estimated cash flows. In particular, 2020 proved to be an atypical year in terms of growth of the economic activity in the country, as well as in the world, due to the Covid-19 pandemic and, consequently, due to measures to contain it, which directly had an impact on trade, industry and services.

A number of assumptions used by Company Management when determining future cash flows can be affected by uncertain events, which, in turn, may give rise to variation in results. Changes in the political and economic model, for example, may lead to upward trend when projecting country risk-rating, increasing the discount rates used in tests.

The tests considered the following key assumptions:

| · | Growth compatible with historical data and perspective for the Brazilian economy growth;

| · | Updating specific after-tax discount rates for the segment tested, obtained through the methodology usually applied by the market, taking into consideration the weighted average cost of capital;

| · | Projected revenue in accordance with the agreements in force and future market expectations, without any expectation for renewal of concession/authorization; and

| · | Expenses broken into cash generating units, projected in view of the budget approved by the Company.

17.5.1 | UHE Colíder

In December 2020, the calculation of value in use took into account the Company's assumptions and budgets and the update of the discount rate after taxes in constant currency of 5,70% p.a. (in 2019, 5.45% p.a.), which derives from the WACC methodology for the electricity generation segment. Depreciating since its entry into commercial operation in March 2019, the reduction in the balance of net assets enabled partial reversal of the balance provisioned for losses.

17.5.2 | Cutia Complex and Bento Miguel Complex

In December 2020, the calculation of value in use took into account the Company's assumptions and budgets and the update of the discount rate after taxes in constant currency of 7.08% p.a. (in 2019, 7.24% p.a.) which derives from the WACC methodology for the electric power generation segment, adjusted for the specific taxation condition of each project. Due to the revision of the discount rate, operating costs and future investments, the entire balance provisioned for losses was reversed.

17.5.3 | UEG Araucária

In December 2020, the calculation of the value in use considered: i) the Company's assumptions and budgets; ii) assumptions for generation, delivery and variable costs; and iii) adjustment of discount rate after taxes in constant currency by 7.87% p.a. (in 2019, 7.76 p.a.), which derive from the WACC methodology for the electric power generation segment, plus additional risk associated with the variation in revenue. By reviewing the assumptions, the budget and the discount rate, the provision for losses was recognized.

17.5.4 | Plants in the Paraná state

Figueira Thermoelectric Plant: in December 2020, the calculation of the value in use of generation assets in the State of Paraná considered: (i) the Company's assumptions and budgets; and (ii) adjustment to the discount rate after taxes in constant currency by 5.70% p.a. (in 2019, 5.45% p.a.), which derive from the WACC methodology for the electricity generation segment. Despite the postponement of the start of the operation to July 2021 (in 2019 it was considered November 2020) and changes in the plant's operating costs and CAPEX, the revision of the coal contract enabled the partial reversal of the impairment recorded for this project.

Other plants: in December 2020, the calculation of the value in use of generation assets in the State of Paraná considered: i) the Company's assumptions and budgets; ii) adjustment to the discount rate after taxes by 5.70% p.a. (in 2019, 5.45% p.a.), which derive from the WACC methodology for the electricity generation segment; and iii) review of operating costs, resulting in the partial reversal of the provisioned balance for losses.

17.5.5 | Cash-generating units that have suffered no impairment

Plants that have suffered no impairment have recoverable amount higher than the carrying amount of property, plant and equipment. The following table shows the percentage by which the recoverable amount (“RA”) exceeds the carrying amount (“CA”) of fixed assets. In addition, the Company carried out a sensitivity analysis, increasing the discount rate shown below by 5% and 10% to assess the risk of impairment of each plant.

17.6 | Property, Plant and Equipment of Copel Telecomunicações

The Company's Management continuously monitors the business environment of the telecommunications segment, paying particular attention to factors such as the increased competitiveness of the sector, the high degree of investment required to maintain its customer base and the expected return from this segment. The reversal of impairment in the period occurred due to depreciation, write-offs and recovery of provisioned equipment, referring to assets for which estimated losses were recorded. However, both the reversal of impairment and the write-offs are shown within the line of net income from discontinued operations, as a result of the divestment process of Copel Telecomunicações and the reclassifications carried out in compliance with accounting standards, as described in Note 40.

17.7 | New plants under construction

17.7.1 | SHPP Bela Vista

With estimated investment of R$ 220,000, this small hydroelectric power plant (SHPP), with installed capacity of 29.81 MW and physical guarantee of 18.4 MW mean, will be built on the Chopim River, in the municipalities of São João and Verê, located in the southwest region of the state of Paraná.

The participation in the A-6 auction held on August 31, 2018 led to sale of 14.7 MW mean in regulated contracts at the original price of R$ 195.70/MWh. The energy sale contracts provide for beginning of energy supply on January 1, 2024, with a 30-year term and annual adjustment by reference to IPCA variation.

17.8.1 | Assets with depreciation rates limited to the concession term

The assets of the original project of the Mauá, Colíder, Baixo Iguaçu, Cavernoso II and SHPP Bela Vista plants, of Copel GeT, and of the Santa Clara and Fundão plants, of Elejor, are considered by the Granting Authority, without full guarantee of indemnification for their residual value at the end of the concession term. This interpretation is based on the Concessions Law No. 8,987/1995 and Decree No. 2,003/1996, which regulate the generation of electricity by independent generators.

Accordingly, from the entry into operation of these assets, including land, depreciation is recognized at the highest rate among that determined by ANEEL or the rate calculated based on the concession period.

As provided for in the concession contracts, subsequent investments not foreseen in the original project, as long as approved by the Granting Authority and not yet amortized, will be indemnified at the end of the concession period and depreciated at the rates established by ANEEL, as from the date of their entry in operation.

Copel issued debentures containing covenants that require the maintenance of certain economic and financial ratios within pre-determined parameters, requiring annual fulfillment and other conditions to be complied with, such as not changing the Company's interest in the capital stock that would represent change of control without prior consent from the debenture holders; not paying out dividends or interest on capital if it is in arrears in relation to honoring any of its financial obligations or not maintaining the financial ratios as determined without prior written consent of the debenture holders. Failing to fulfill these conditions may lead to accelerated redemption of debentures and regulatory penalties.

An appeal has been brought by ANEEL, pending judgment by the Federal Court of the 1st Region. The practical consequence of the ruling was, at the time it exempted ESBR, to expose the distributors with whom it entered into power trading contracts (CCEARs) to the Short-Term Market and to the high value of the Settlement Price of the Differences (Preço de Liquidação das Diferenças - PLD, in Portuguese) in the period, including Copel DIS. This occurred because the rules for the sale of electricity require that all energy consumed should have a corresponding contractual coverage.

30 | Equity

30.1 | Capital

Capital consists of common and preferred shares. Each common share entitles its holder to one vote in the general shareholders’ meetings. Preferred shares do not have voting rights and have two classes “A” and “B”.

According to Article 17 and following paragraphs of Federal Law No. 6,404/76, dividends paid to preferred shares must be at least 10% higher than those paid to common shares.

Class “A” preferred shares have priority in the reimbursement of capital and in the distribution of minimum dividends of 10% p.a. (non-cumulative), calculated based on the capital represented by this class of shares.

Class “B” preferred shares have priority in the reimbursement of capital and the right to the distribution of dividends, calculated as 25% of adjusted profit or loss for the year, pursuant to the corporate legislation and to the Company’s by-laws, calculated proportionately to the capital represented by the shares of this class. Dividends for Class “B” have priority only over the common shares and are only paid out of the remaining profits payment of priority dividends of class “A” shares.

On March 11, 2021, the General Meeting approved the submission of the proposal for comprehensive amendment and consolidation of the Company's bylaws, including, among other changes, the share split of the Company, in the proportion of one share for ten shares, so that, for every one share issued by the Company, nine new shares of the same class and type will be credited.

At December 31, 2020, paid-in capital is R$ 10,800,000 (R$ 10,800,000 as at December 31, 2019). It includes shares (with no par value) and the main shareholders are presented below, already considering the adjusted number of shares after the split approved by Management:

Class “B” preferred shares | 1,243,725 | 316,499 | 186,223

The gross value per share presented were calculated based on the new number of shares, after the share split approved at the General Meeting, as described in Note 30.1.

In accordance with the legal and statutory provisions in effect, the basis for calculating mandatory dividends is obtained from net income, less the quota allocated to the legal reserve. However, Management decided to add to the calculation basis the realization of the equity valuation adjustments, which is dealt with in IAS 16, 40 and IFRS 1, in order to void the effect of the increase in depreciation expense arising from the adoption accounting standards, as well as IAS 16 - Property, Plant and Equipment. This procedure reflects the Company's shareholder remuneration policy, which will be practiced during the realization of the entire reserve for equity valuation adjustments.

30.4.1 | Additional proposed dividend from non-capitalized revenue reserve

Considering that Copel has profit retention reserves corresponding to the allocation of prior-year profits that have not yet been capitalized, that a relevant portion of the profit for 2020 has not yet been realized financially (reflecting the final and unappealable decision for the lawsuit that recognized the right of Copel DIS to exclude from the PIS and COFINS calculation basis the full amount of ICMS separately stated in the sales invoices) and, finally, the need to allocate part of the profit for 2020 to the investment program expected for 2021, the payment of the proposed additional dividend will be made with a balance of profit reserves from previous non-capitalized periods.

31.4 | Copel DIS anual tariff adjustment

ANEEL approved the result of Copel DIS's Annual Tariff Adjustment through Homologatory Resolution No. 2,704, dated June 23, 2020, authorizing average adjustment of 0.41 (3.41% in 2019) applied to consumers and whose application occurred in full to tariffs as from June 24, 2020.

The tariff recomposition includes: 0.79% resulting from the update of Parcel B (operating costs, depreciation and remuneration); 7.82% related to the updating of Parcel A (energy, transmission, charges and sunk revenue); 1.81% related to the inclusion of financial components; and -10,01% that reflect the withdrawal of financial components from the previous tariff process.

There was a reduction for the categories of customers: residential, 0.95%; commerce and services at low voltage, of 0.83%; and for public lighting, 0.93%. High voltage customers had an average increase of 1.13%.

This readjustment already considers the impacts of Covid Account, according to Decree 10,350/2020 and Aneel Normative Resolution 885/2020, in the amount of R$ 536,359, whose funds were received on July 31, 2020.

Determining fair values

a) | Equivalent to their respective carrying values due to their nature and terms of realization.

b) | Fair value is calculated based on information made available by the financial agents and the market values of the bonds issued by the Brazilian government

c) | The criteria are disclosed in Note 4.4 to the financial statements.

d) | The fair values of generation assets approximate their carrying amounts, according to Note 4.4 of these Financial Statements.

e) | The fair values of assets and liabilities are equivalent to their carrying amounts according to Note 4.15 of these Financial Statements.

f) | Investments in other companies, stated at fair value, which is calculated according to the price quotations published in an active market, for assets classified as level 1 and determined in view of the comparative assessment model for assets classified as level 2.

g) | The cost of the last borrowing taken out by the Company is used as a basic assumption IPCA + Spread de 4.8165%, for discount of the expected payment flows.

h) | The Company based its calculation on the comparison with a long-term and post-fixed National Treasury Bond (NTN-B) maturing on August 15, 2026, which yields approximately 3.09% p.a. plus the IPCA inflation index.

i) | Receivables related to the concession agreement for providing electricity generation services under quota arrangements, having their fair value calculated by expected cash inflows, discounted at the rate established by ANEEL auction notice 12/2015 (9.04%).

j) | Calculated from the Unit Price quotation (PU) for December 31, 2020, obtained from the Brazilian Association of Financial and Capital Markets (ANBIMA), net of unamortized financial cost.

k) | Actual net discount rate of 8.64% p.a., in line with the Company's estimated rate for long-term projects.

Other temporary investments (h) | 22,385 | 27,734
| 11,140,975 | 10,235,732

a) | The Company manages the credit risk of its assets in accordance with the Management’s policy of investing virtually all of its funds in federal banking institutions. As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime private banks.

b) | The risk arises from the possibility that the Company might incur losses resulting from difficulties to receive its billings to customers. This risk is directly related to internal and external factors to Copel. To mitigate this type of risk, the Company manages its accounts receivable, detecting the classes of consumers most likely to default, implementing specific collection policies and suspending the supply and/or recording of energy and the provision of service, as established in contract and regulatory standards.

c) | Management believes this credit risk is low because repayments are secured by resources from dividends.

d) | Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, corresponding to the costs not recovered through the tariff.

e) | Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, referring to investments in infrastructure not recovered through the tariff.

f) | Management considers the risk of such credit to be low, as the contract for the sale of energy by quotas guarantees the receipt of an Annual Generation Revenue - RAG, which includes the annual amortization of this amount during the concession term.

g) | For the generation concession assets, ANEEL published Normative Resolution 596/2013, which deals with the definition of criteria for calculating the New replacement value (Valor novo de reposição – VNR), for the purposes of indemnification. Management's expectation of indemnification for these assets supports recoverability of the balances recorded.

h) | This risk arises from the possibility that the Company might incur losses resulting from the volatility on the stock market. This type of risk involves external factors and has been managed through periodic assessment of the variations occurred in the market.

35.2.2 | Liquidity risk

The Company's liquidity risk consists of the possibility of having insufficient funds, cash or other financial assets, to settle obligations on their scheduled maturity dates.

The Company manages liquidity risk relying on a set of methodologies, procedures and instruments applied to secure ongoing control over financial processes to ensure proper management of risks.

Investments are financed by incurring medium and long-term debt with financial institutions and capital markets.

Short, medium and long-term business projections are made and submitted to Management bodies for evaluation. The budget for the next fiscal year is annually approved.

Medium and long-term business projections cover monthly periods over the next five years. Short-term projections consider daily periods covering only the next 90 days.

The Company permanently monitors the volume of funds to be settled by controlling cash flows to reduce funding costs, the risk involved in the renewal of loan agreements and compliance with the financial investment policy, while concurrently keeping minimum cash levels.

The following table shows the expected undiscounted settlement amounts in each time range.

35.2.3 | Market risk

Market risk is the risk that the fair value or the future cash flows of a financial instrument shall oscillate due to changes in market prices, such as currency rates, interest rates and stock price. The purpose of managing this risk is to control exposures within acceptable limits, while optimizing return.

a) | Foreign currency risk (US Dollar)

This risk comprises the possibility of losses due to fluctuations in foreign exchange rates, which may reduce assets or increase liabilities denominated in foreign currencies.

The Company's foreign currency indebtedness is not significant, and it is not exposed to foreign exchange derivatives. The Company monitors all relevant foreign exchange rates.

The effect of the exchange rate variation resulting from the power purchase agreement with Eletrobras (Itaipu) is transferred to customers in Copel DIS's next tariff adjustment.

The exchange rate risk posed by the purchase of gas arises from the possibility of Compagás reporting losses on the fluctuations in foreign exchange rates, increasing the amount in Reais of the accounts payable related to the gas acquired from Petrobras. This risk is mitigated by the monitoring and transfer of the price fluctuation through tariff, when possible. The Company monitors these fluctuations on an ongoing basis.

Sensitivity analysis of foreign currency risk

The Company has developed a sensitivity analysis in order to measure the impact of the devaluation of the US dollar on its loans and financing subject to currency risk.

The valuation of the financial instruments considers the possible effects on profit and loss and equity of the risks evaluated by the Company's Management on the reporting date for the financial instruments, as recommended by IFRS 7 - Financial Instruments: Disclosure. Based on the equity position and the notional value of the financial instruments held as of December 31, 2020, it is estimated that these effects will approximate the amounts stated in the above table in the column for the forecast probable scenario, since the assumptions used by the Company are similar to those previously described.

The baseline scenario takes into account the existing balances on the date of these financial statements and the probable scenario assumes a variation in the foreign exchange rate - prevailing at the end of the period (R$/US$ 5.15) based on the median market expectation for 2021 according to the Focus Report issued by the Central Bank of Brazil. Additionally, the Company continues to monitor scenarios 1 and 2, which consider a deterioration of 25% and 50%, respectively, in the main risk factor of the financial instrument in relation to the level used in the probable scenario, as a result of extraordinary events that may affect the economic scenario.

|  | (467,551) | 4,202 | (111,636) | (227,473)

b) | Foreign exchange risk - euro

This risk arises from the possibility of loss due to fluctuations in exchange rates affecting fair value of Non-Deliverable Forward (NDF) transactions. These derivatives were contracted considering that in the supply contracts for wind turbines of companies in the Jandaíra wind complex, controlled by Copel GeT, disbursement installments in Euro are foreseen. Sporadic gains and losses are recognized in the Company's statement of income.

Based on the notional amount of 15,5 million euros outstanding as of December 30, 2020, the fair value was estimated by the difference between the amounts contracted under the respective terms and the forward currency quotations (B3 reference rates), discounted to present value at the fixed rate as of the same date. The active balance, recorded as of December 30, 2020, is shown in Note 12. The liability balance, as of December 31, 2019, is presented in Note 28.

Sensitivity analysis of operations with derivative financial instruments

The Company developed a sensitivity analysis in order to measure the impact from exposure to fluctuation in exchange rate to Euro (€).

For the base scenario, the accounting balances recorded on the date of these financial statements were considered and for the probable scenario, the balances updated with the future currency quotations (B3 reference rates on February 26, 2021) were considered and adjusted to present value by the pre-tax rate at same date. Additionally, the Company continues to monitor scenarios 1 and 2, which consider the 25% and 50% rise or fall in future quotes applied on the probable scenario, as a result of extraordinary events that may affect the economic scenario.

| Decrease | 23,308 | 29,230 | 3,140 | (23,541)

c) | Interest rate and monetary variation risk

This risk comprises the possibility of losses due to fluctuations in interest rates or other indicators, which may reduce financial income or financial expenses or increase the financial expenses related to the assets and liabilities raised in the market.

The Company has not entered into derivative contracts to cover this risk but has been continuously monitoring interest rates and market indexes in order to observe any need for contracting.

Sensitivity analysis of interest rate and monetary variation risk

The Company has developed a sensitivity analysis in order to measure the impact of variable interest rates and monetary variations on its financial assets and liabilities subject to these risks.

The valuation of the financial instruments considers the possible effects on profit and loss and equity of the risks evaluated by the Company's Management on the reporting date for the financial instruments, as recommended by IFRS 7 - Financial Instruments: Disclosure. Based on the equity position and the notional value of the financial instruments held as of December 31, 2020, it is estimated that these effects will approximate the amounts stated in the above table in the column for the forecast probable scenario, since the assumptions used by the Company are similar to those previously described.

The baseline scenario takes into account the existing balances in each account as of December 31, 2019 2020 on the date of these financial statements and the probable scenario assumes balances reflecting varying indicators CDI/Selic – 4.00%, IPCA – 3.98%, IGP-DI – 6.85%, IGP-M - 8,98% and TJLP – 4.98%, estimated as market average projections for 2021 according to the Focus Report issued by the Central Bank of Brazil, except TJLP that considers the Company's internal projection. Additionally, the Company continues to monitor scenarios 1 and 2, which consider a deterioration of 25% and 50%, respectively, in the main risk factor of the financial instrument in relation to the level used in the probable scenario, as a result of extraordinary events that may affect the economic scenario.

35.2.4 | Electricity shortage risk

Approximately 64% of installed capacity in Brazil currently comes from hydroelectric generation, as informed by the Generation Information Bank of ANEEL, which makes Brazil and the geographic region in which we operate subject to unpredictable hydrological conditions, due to non-cyclical deviations of mean precipitation. Unsatisfactory hydrological conditions may cause, among other things, the implementation of comprehensive programs of electricity savings, such as rationalization or even a mandatory reduction of consumption, which is the case of rationing.

Since 2014, the reservoirs of the Southeast/Midwest, North and Northeast Brazilian regions have been subject to adverse climate situations, leading agencies responsible for this industry to adopt water resources optimization measures to guarantee fully meeting electricity demand. In the first quarter of 2020, the reservoirs in the Northeast and North recovered their levels, which practically reduces the risk of rationing in these subsystems to zero. As the system is interconnected, the South and Southeast/Midwest subsystems, despite being at lower storage levels, results in having a low risk of energy shortage since they can make use of the energy stored in the other two subsystems.

The Electric Sector Monitoring Committee (CMSE) has maintained the energy deficit risk indicators within the safety margin in short-term projections. The same position is adopted by ONS regarding the risk of deficit in the medium term, as stated in the 2020-2024 Energy Operation Plan - PEN 2020.

F-122

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

Although dam storage levels are not ideal, from the standpoint of regulatory agencies, when combined with other variables, such as a slower consumption growth, they are sufficient to keep the risk of deficit within the safety margin established by the National Energy Policy Council (Conselho Nacional de Política Energética - CNPE, in Portuguese) (maximum risk of 5%) in all subsystems.

35.2.5 | Risk of GSF impacts

The Energy Reallocation Mechanism (Mecanismo de Realocação de Energia - MRE, in Portuguese) is a system of redistribution of electric power generated, characteristic of the Brazilian electric sector, which has its existence by the understanding, at the time, that there is a need for a centralized operation associated with a centrally calculated optimal price known as PLD. Since generators have no control over their production, each plant receives a certain amount of virtual energy which can be compromised through contracts. This value, which enables the registration of bilateral contracts, is known as Physical Guarantee (Garantia Física - GF, in Portuguese) and is also calculated centrally. Unlike PLD, which is calculated on a weekly basis, GF, as required by Law, is recalculated every five years, with a limit of increase or decrease, restricted to 5% by revision or 10% in the concession period.

The contracts need to have an energy physical guarantee basis. This is done, especially, through the allocation of power generated received from the MRE or purchase. The GSF is the ratio of the entire hydroelectric generation of the MRE participants to the GF sum of all the MRE plants. Basically, the GSF is used to calculate how much each plant will receive from generation to back up its GF. Thus, knowing the GSF of a given month the company will be able to know if it will need to back up its contracts through purchases.

Whenever GSF multiplied by GF is less than the sum of contracts, the company will need to buy the difference in the spot market. However, whenever GSF multiplied by GF is greater than the total contracts, the company will receive the difference to the PLD.

The low inflows that have been recorded since 2014, as well as problems with delays in the expansion of the transmission system have resulted in low GSF values, resulting in heavy losses for the companies holding MRE participating hydroelectric projects.

For plants with contracts in the Free Contracting Environment - ACL, the main way to manage the low GSF risk is not to compromise the entire GF with contracts, approach currently adopted by the Company.

For the contracts in the ACR, Law 13,203/2015 allowed the generators to contract insurance for electricity demand (load), by means of payment of a risk premium. Copel adopted this approach to protect contracts related to energy generated by the Mauá, Santa Clara, Fundão, Baixo Iguaçu and Colíder Thermoelectric Plants and Cavernoso II Small HPP.

For the distribution segment, the effects of the GSF are perceived in the costs associated with quotas of Itaipu, of Angra and the plants whose concessions were renewed in accordance with Law 12,783/2013, as well as in the costs of the contracts for power availability with thermoelectric plants. This is a financial risk, since there is guarantee of neutrality of expenses with energy purchases through a tariff transfer.

35.2.6 | Risk of non-renewal of concessions - generation and transmission

The extension of energy generation and transmission concessions, achieved by Law No. 9,074/1995, is regulated by Law No. 12,783/2013, which was amended by Law No. 14,052 of September 8, 2020, regarding the deadline for requesting an extension of concessions.

According to the new law, the concession operator should request extension of concession at least 36 months before the final contract date or after granting of concessions to hydroelectric power generation and electric power transmission and distribution plants, and of up to 24 months for thermoelectric plants. The Concession Grantor may advance effects of extension by up to 60 months counted as of contract or grant date and may also define initial tariff or revenue, which includes the definition of the tariff or initial revenues for the generation and transmission ventures (RAG - Annual Generation Revenue and RAP - Permitted Annual Revenue, respectively).

Concessions for hydroelectric power generation and electric power transmission may be extended, at the discretion of the granting authority, only once, for a period of up to 30 years. Thermoelectric power generation concessions have an extension term limited to 20 years.

In 2019, Decree No. 10,135/2019 was published, which regulated the granting of concession contracts in the electricity sector associated with privatization through sale of control by holder of a public service concession for electricity generation, having as one of the conditioning factors the alteration of the exploration regime to Independent Power Producer (IPP). According to the Decree, the manifestation of sale of the concession must take place within up to 42 months from the date of the related formal agreement, and any sale must take place within up to 18 months from the concession end date. If sale of control of the venture does not occur within the specified period, the plant must be subject to auction by the granting authority and the same concessionaire can participate in the auction, if it meets the qualification conditions.

Copel has 2 plants whose concession ends in the next 5 years.

For HPP Governador Bento Munhoz da Rocha Netto (HPP GBM) (1,676 MW), whose concession will end in 2023, the Company has not expressed any interest in extending the concession, as internal studies have shown that the extension through early change of the exploration regime would be economically and financially disadvantageous in relation to exploration of the plant under the current regime until concession end. On March 3, 2020, Copel GeT transferred the concession of HPP GBM to subsidiary F.D.A. Geração de Energia Elétrica S.A. with the purpose of, if the studies carried out by Copel GeT point to the advantage of the operation, divesting the control of this concessionaire and, thus, allow a new concession grant for 30 years.

With respect to HPP São Jorge, whose concession ends in 2024, Copel did not express interest in the renewal and intends, at the end of the concession, to request ANEEL to convert the granting of concession into granting of registration.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

Regarding the Figueira HPP concession, expired in March 2019, the Company awaits the conclusion of the related ANEEL and MME procedural steps to execute any amendment to the Concession Agreement. The plant is undergoing a modernization process and will have as direct benefits the improvement in energy efficiency and the reduction of pollutant emissions in the atmosphere, in comparison with the old plant.

According to the new law, the Company may express its intention to extend the concession of the Apucaraninha HPP until October 2022, and the Guaricana and Chaminé HPPs until August, 2023. If the Company does not express an interest in the extension of the current regime at its final term, be granted to the Company in the condition of registration, and the other concessions, at their final term, must be returned to the Concession Grantor.

Copel GeT does not have any transmission concession ending in the next ten years.

35.2.7 | Risk on non-renewal of concessions – distributions of electricity

The fifth amendment to Copel DIS's concession contract No. 46/1999 imposes economic and financial efficiency covenants and indicators that consider the duration and frequency of service interruptions (DECi and FECi). Failure to comply with the conditions will result in termination of the concession (clause eighteen, subclause one), with due regard for the provisions of the contract, particularly the right to full defense and adversary system.

35.2.8 | Risk of non-extension of the gas distribution concession

In the event of termination of the concession at the end of the contractual term, Compagás will be entitled to compensation for investments made in the last 10 years prior to the end of the concession at their depreciated replacement value, according to the contractual clause.

35.2.9 | Risk of overcontracting and undercontracting of electricity

Under the current regulatory model, the agreement for purchase of electric power by distributors is regulated by Law 10,484/2014 and Decree 5,163/2004, which determine that the purchase of energy must be in the volume necessary to serve 100% of the distributor's market.

The difference between the costs remunerated by the tariff and those actually incurred in the power purchases are fully passed on to captive consumers, as long as the distributor presents a contracting level between 100% and 105% of its market. However, if distributors determine contracting levels lower or higher than the regulatory limits, there is the assurance of neutrality if it is identified that such violation derives from extraordinary and unforeseen events that are not manageable by the buyer.

In the last years, the distribution segment has been exposed to a general overcontracting scenario, as most companies determined contracting levels higher than 105%. Considering that several factors that have contributed to this situation are extraordinary and unavoidable by the distributors, such as the involuntary allocation of physical guarantee quotas and the broad migration of consumers to the free market and more recently, in 2020, the effects on the market of the governmental measures of social isolation implemented in the fight against the pandemic of the coronavirus Sars-CoV-2 (Covid-19), which caused a significant retraction in the market of distribution concessionaires, ANEEL and MME implemented a series of measures aiming at the mitigation of overcontracting.

COMPANHIA PARANAENSE DE ENERGIA – COPEL and Subsidiaries Notes to the Consolidated Financial Statements, continued For the years ended December 31, 2020, 2019 and 2018 All amounts expressed in thousands of Brazilian reais, unless otherwise stated

In relation to the contracting of, the scenarios of supply and demand indicate the occurrence of over contracting 105.8% by Copel DIS. Nevertheless, considering that this situation arises mainly from the migration of consumers to the free market and load reduction by the Covid-19 pandemic, it is considered that the Company maintains the guarantee of neutrality preserved, since this factors are subject to the recognition of involuntary over contracting.

35.2.10 | Gas shortage risk

The natural gas market in Paraná is composed of Compagás consumers (non-thermal market) and the Araucária Thermoelectric Plant (UEG Araucária). This market, at the moment, is supplied by contracts with Petrobras that uses the transportation infrastructure of the Brazil-Bolivia gas pipeline (Gasbol). Compagás has a contract for the supply of natural gas from Bolivia until December 2023 and will make a new public bidding for the supply of natural gas as from January 2022. UEG Araucária, on the other hand, negotiates short-term natural gas contracts for not having electricity generated contracted in the regulated environment.

In the current situation of the natural gas sector in Brazil, the New Gas Market program is coordinated by the Ministry of Mines and Energy together with the Civil House of the Presidency of the Republic, the Ministry of Economy, the Administrative Council for Economic Defense, the National Petroleum Agency and the Energy Research Company - EPE, whose purpose is to open the natural gas market in order to make it dynamic, competitive, integrated with the electric and industrial sector, with an improved regulation.

Within the scope of the New Gas Market, the offer of natural gas already demonstrates growth and diversification, having as alternatives the import of gas from Bolivia, import of liquefied natural gas (LNG) that has a large world offer, use of natural gas from onshore basins and greater use of natural gas from the pre-salt which has large volumes to be extracted.

In relation to the transportation network, the changes in regulation to allow access to new agents, the public call of TBG (Gasbol transporter) that establishes a new capacity contracting regime in the gas pipeline and the Gas Pipeline Indicative Plan (PIG) coordinated by EPE, give a vision of better structuring of the sector and adequate planning to meet current and future demands, even though investments are needed for the latter.

A possible shortage in gas supply could result in losses to Copel due to a reduction in revenue from the natural gas distribution service provided by Compagás, as well as any penalty resulting from non-compliance with the obligations contained in the concession contract. In addition, in this scenario, UEG Araucária would probably be kept out of operation. However, this risk is considered low in view of the situation of the New Gas Market.

35.2.11 | Risk of non-performance of windfarms

The power generation purchase and sale contracts for wind power are subject to performance clauses, which provide for a minimum annual and four-year generation of the physical guarantee committed in the auction. Ventures are subject to climatic factors associated with wind velocity uncertainties. Non-compliance with what is stated in the agreement may jeopardize future revenues of the Company. At December 31, 2020, the consolidated balance recorded in liabilities referring to the non-performance is demonstrated in note 28.

35.2.12 | Risk related to price of power purchase and sale transactions

The Company operates in the electricity purchase and sale market with the objective of achieving results with variations in the price of electricity, respecting the risk limits pre-established by Management. This activity, therefore, exposes the Company to the risk of future electricity prices.

Future electricity purchase and sale transactions are recognized at fair value through profit or loss, based on the difference between the contracted price and the market price of operations on the balance sheet date.

Based on the notional amounts of R$ 6,065,065 for purchase contracts and R$ 6,634,477 for electricity sales contracts open on December 31, 2020, the fair value was estimated using the prices defined internally by the Company in the last week of December 2020, which represented the best estimate of the future market price. The discount rate used is based on the NTN-B rate of return disclosed by ANBIMA, on December 31, 2020, adjusted for credit risk and additional project risk.

The balances referring to these outstanding transactions as of December 31, 2020 are shown below.

| Assets | Liabilities | Net
Current | 51,359 | (35,298) | 16,061
Noncurrent | 638,172 | (308,108) | 330,064
| 689,531 | (343,406) | 346,125

Sensitivity analysis on the power purchase and sale transactions

The Company developed a sensitivity analysis in order to measure the impact of changes in future prices. For the base scenario, the accounting balances recorded on the date of these financial statements were considered and for the probable scenario, the balances updated with the market price curve and NTN-B rate were considered. Additionally, the Company continues to monitor scenarios 1 and 2, which consider the 25% and 50% rise or fall applied to future prices considered in the probable scenario, as a result of extraordinary events that may affect the economic scenario.

| Price | Baseline | Projected scenarios
| variation | 12.31.2020 | Probable | Scenario 1 | Scenario 2
Unrealized gains (losses) on purchase and sale of energy | Increase | 346,125 | 332,741 | 356,496 | 380,117
Decrease | 346,125 | 332,741 | 309,255 | 285,635

35.2.13 | Counterparty risk in the energy market

Since free energy market still does not have a counterparty acting as guarantor of all agreements (clearing house), there is a bilateral risk of default. Thus, the Company is exposed to the risk of failure in the supply of energy contracted by the seller. In the event of such failure, the Company must buy energy at the spot market price, being further subject to regulatory penalties and loss of amounts paid.

The Company follows a policy that establishes limits for possible operations with each counterparty, after analyzing its credit worthiness, maturity and history.

In addition, even if our policy is more restrictive, and the counterparties present good financial condition, the Company is exposed to systemic events in which the default of one agent ends up affecting other energy trading companies in a "domino effect" until reaching the Company's counterparties.

35.3 | Capital management

The Company seeks to keep a strong capital base to maintain the trust of investors, creditors and market and ensure the future development of the business. Management also strives to maintain a balance between the highest possible returns with more adequate levels of borrowings and the advantages and the assurance afforded by a healthy capital position. Thus, it maximizes the return for all stakeholders in its operations, optimizing the balance of debts and equity.

The Company monitors capital by using an index represented by adjusted consolidated net debt divided by adjusted consolidated EBITDA (Earnings before interest, taxes, depreciation and amortization), for the last twelve months. The corporate limit established in the debt indentures provides for maintenance of ratio below 3.5 while any expectation of failing to meet this target will prompt Management to take steps to correct its course by the end of each reporting period.

As of December 31, 2020, the ratio attained is shown below:

On November 9, 2020, there was a public auction session related to the sale of 100% of the shares issued by Copel Telecomunicações owned by the Company.

We highlight that during the studies for the sale of Copel Telecomunicações some assets were considered strategic for Copel Distribuição, Copel Geração e Transmissão, wholly owned subsidiaries of Copel, and some other administrative assets that will be maintained within Copel itself or other subsidiaries. In addition, in the divestment process, Management defined that all employees registered with Copel Telecom will be reallocated to other Copel subsidiaries. In view of these definitions, both the balances of assets that will be maintained in the Company and the total obligations with employees and managers, including post-employment benefit obligations and associated deferred taxes, were not reclassified to the asset accounts and associated liabilities were classified as held for sale.

The balances of other assets and liabilities that were reclassified, which are presented in a specific line in the balance sheet are presented below. In compliance with the accounting standard, balances are measured at book values, since they are less than fair values fewer selling expenses.

Reclassified assets and liabilities are part of the telecommunications segment which, with the divestment of Copel Telecomunicações, will be discontinued at Copel .

In addition, the total of R$ 74,437 related to Copel Telecomunicações contingent liabilities (not recorded in the balance sheet) was disregarded in Note 29.2.

Therefore, the revenues, costs and expenses as well as the cash flow movement resulting from these reclassified assets and liabilities were presented in separate lines, as a discontinued operation, both in the Income Statement and in the Cash Flow Statement.

It should also be noted that as of October 1, 2020, the depreciation and amortization of assets that will be sold ceased, after their reclassification to current assets, in the line item Assets held for sale, in compliance with what determines item 25 of IFRS 5.

41.2 | Cyber attack

In January 2021, Copel became aware that it was exposed to a cyber incident in its information technology (“IT”) environment that interrupted some systems and partially affected the Company's administrative operations. Copel involved leading experts, including external experts, in cybersecurity and general IT controls, launched a comprehensive containment and remediation effort, informed the competent authorities and initiated a forensic investigation. In the first weeks of February 2021, Copel had reestablished all of its administrative systems and resumed operations in all of its businesses.

The cyber incident did not have a significant impact on the revenue performance of the Company's business for the year ended December 31, 2020, despite having resulted in a slight delay in billings in the first days of February 2021 resulting from the preventive measures to identify the scope of the incident. The incremental expense incurred as a result of the cyber incident was not material, and no provision was identified to be recognized at December 31, 2020.

On February 1, 2021, understanding better the event that occurred, Copel issued Notice to the Market 07/21 informing that part of its systems were temporarily unavailable, except for the operating systems, which provide energy supply and telecommunication services, which continued to operate without interruption.

Copel performed extensive procedures to validate the accuracy and integrity of the information and no access to the computing environment that concentrates the Company's ERP and billing systems, as well as folders and/or files with the presence of sensitive personal data, was identified, so there is no indication that the accuracy and completeness of the financial information has been affected as a result of the incident.

41.3 | Additional proposed dividend from non-capitalized revenue reserve

On March 11, 2021, the General Meeting approved the revision of the Company's Articles of Incorporation, which includes, among other changes, the possibility for the Board of Directors to decide on the distribution of interim dividends, interim dividends or interest on capital based on retained earnings, in the revenue reserves and in the profit for the current year, recorded in the semi-annual or quarterly interim financial statements, provided that in conformity with the dividend policy and without prejudice to the subsequent ratification of the General Meeting.

On March 17, 2021, the Board of Directors approved the management's proposal for the payment of interim dividends based on the profit retention reserve, as pointed out in Note 30.4.1.

41.4 | Amendment to the Articles of Incorporation

On March 11, 2021, the General Meeting approved the amendment to the Company's Articles of Incorporation, as per Notice to the Market 08/21. In addition to the change already mentioned in Note 41.3 above, the amendment also included other changes that represent advances in corporate governance and, among them, the approval of the Company's Units program, which includes the share split described in Note 30.1.
