2. Financial Performance

The analyzes below refer to the fourth quarter of 2018 and to the accumulated of year compared to the same period of 2017.

2.1 Operating Revenues

In 4Q18, net operating revenue totaled R$3,671.1 million, down 6.1% from R$3,910.7 million in 4Q17. This decrease is mainly due to (i) the negative R$55.0 million in result of “sectorial assets and liabilities result” in 4Q18, over a positive R$381.1 million in 4Q17, resulting from lower costs with electricity purchased for resale, mainly due to the lower hydrological deficit (18.1% in 4Q18 vs. 30.7% in 4Q17) and the lower average spot price (PLD) in the period (R$158.24/MWh in 4Q18 vs. R$398.09/MWh in 4Q17); and (ii) the 17.3% decrease in “electricity sales to distributors” given that TPP Araucária dispatched 195.2 GWh in 4Q17, while in 4Q18 there was no dispatch.

These effects were partially offset by the 17.4% increase in “electricity sales to distributors”, due to the 6.1% increase in the volume of energy sold to final consumers - notably the consumption of the industrial free market of Copel GeT and Copel Com, up 26.0% over 4Q17 - and Copel Distribuição’s tariff adjustment, effective as of June 24, 2018, which adjusted the electric energy tariff (TE) by 15.61%.

The following are also noteworthy:

(i) 69.4% increase in “distribution of piped gas” revenue, mainly due to the 44.6% increase in natural gas consumption and the tariff adjustment applied in 2018;

(ii) 43.2% increase in “other operating revenues”, especially due to the 51.3% increase in revenue from equipment and structures leases and rents, mainly due to the receipt of a legal dispute favoring Copel Dis;

(iii) 17.1% increase in “telecommunications revenues” due to the expansion of the service to new clients; and

(iv) the “use of the main distribution and transmission grid”, with a 1.4% improvement, mainly due to the 1.8% growth in the grid market, Copel Dis’ tariff adjustment (16.42% increase in TUSD from June 24, 2018), partially offset by the decrease in TUST’s revenue in the quarter as a result of an adjustment by Aneel in the RBSE calculations referring to contract no. 060/2001 and the reduction of 50% of APR in contract no. 075/2001 as provided for in the agreement.

Year-to-date, the net operating revenues increased by 6.5%, mainly reflecting the 172.0% increase in eletricity sold to free customers of Copel Comercialização and the energy tariff (TE) adjustments of Copel Distribuição - 10.28% and 15.61% in June 2017 and June 2018, respectively, positively impacting the revenues from ‘electricity sales of customers’, up 18.5%. The following increases were also noteworthy: +22.5% in revenues from ‘distribution of piped gas’ and +18.5% in ‘telecommunications revenues’, due to the 2.9% improvement in the gas market and the expanded base of Copel Telecom’s customers, respectively.

This growth was partially offset by the decrease of (i) 12.9% in the ‘electricity sales of distributors’ revenue due to the lower average PLD (R$287.62 in 2018 vs. R$318.15 in 2017) and by UTE Araucária not having dispatched energy in 2018, while in 2017, the plant traded 195.2 GWh; and (ii) 4.1% in the ‘use of the main distribution and transmission grid’, mainly reflecting the recognition, in 1Q17, of R$183.0 million arising from the remeasurement of transmission assets referring to RBSE in the concession agreement 060/2001.

2.2 Operating Costs and Expenses

In 4Q18, operating costs and expenses fell 13.8%, totaling R$3,120.1 million, mainly due to the 22.8% decrease in “electricity purchased for resale”, mainly due to i) the improved hydrological scenario, with GSF major (81.9% in 4Q18 vs. 69.3% in 4Q17) and the lower average PLD (R$158.24/MWh in 4Q18 vs. R$398.09/MWh in 4Q17), and (ii) the lower volume of eletricity purchased in bilateral agreements; partially offset by the higher US dollar prices in 4Q18 (R$3.81 vs. R$3.25 in 4Q17), incurring on the energy supplied by Itaipu.

This decrease in costs was also significantly impacted by the lower “provisions and reversals” (R$35.2 million provisioned in 4Q18 vs. R$268.4 million in 4Q17), specially due to the reversal of R$92.7 million, related to an indemnification lawsuit against third parties on alleged damages by the implementation of hydroelectric project, and the 29.2% decrease in the provision for labor lawsuits litigation, partially offset by a R$34.6 million impairment loss, of which R$58.3 million was provisioned at the Colíder HPP, due to the postponement of the start-up of this plant, and the R$32.8 million reversal in the Bento Miguel Wind Complex, resulting from an increase in generation estimate. The following table sets forth the amounts related to impairment.

PMSO costs, excluding estimated losses, provisions and reversals, increased 3.8%, mainly due to a provision referring to the deactivation of equipment infrastructure in Copel Telecom clients over the year, impacting the line of “other costs and operating expenses”, partially offset by the 9.9% decrease in “personnel and management”, due to the R$20.2 million reversal related to employees who declined the Indemnification for Voluntary Dismissal (PDI).

Disregarding the effect of the provision for indemnification related to PDI (reversal of R$20.2 million in 4Q18 and provision of R$22.5 million in 4Q17), personnel costs remained practically stable with an increase of 0.2%, remaining below the accumulated inflation of 3.7% in the last 12 months.

The following variations are also noteworthy:

(i) 99.0% decrease in costs with “materials and suppliers for power electricity”, since TPP Araucária did not dispatch energy in 4Q18, while in 4Q17 the plant generated 195.2 GWh;

(ii) 46.9% increase in “charges of the main distribution and transmission grid”, mainly reflecting the effect of CCEE’s decision in 4Q17 to transfer the surplus of resources accumulated in CONER to the market (affecting the ESS), as well as the higher costs with the use of the system - basic network, due to the TUST readjustment in June 2018 and the readjustment of Itaipu’s electric energy transmission tariff; and

(iii) 100.7% increase in “natural gas and suppliers for the gas business”, mainly due to the exchange rate change and the increase of 44.6% in the consumption of natural gas.

In 2018, operating costs and expenses totaled R$12,676.6 million, up 5.8%. This is mainly due to (a) the 65.3% increase in “charges of the main distribution and transmission grid”, mainly from higher expenses with charges to use the system - basic network, given the TUST adjustment in June 2018 and 2017 (when the indemnity referring to RBSE-related assets became part of the RAP, while in 2018 the impact was on the full year); (b) the 3.2% increase in “electricity purchased for resale”, due to (i) the purchase of 4,101 GWh by Copel Comercialização in 2018 (higher than the 2,644 GWh in 2017), and (ii) the higher exchange rate of US dollar in 2018 (R$3.86 over R$3.19 in 2017), focusing on the electric energy supplied by Itaipu; and (c) the 33.3% increase in natural gas expenses due to the market growth of Compagas.

2.3 Equity in the Earnings of Subsidiaries

Equity in the earnings of investees reflects gains and losses from investments in Copel’s investees and jointly-controlled company, are presented in the table below.

2.4 EBITDA

In 4Q18, earnings before interest, taxes, depreciation and amortization reached R$756.6 million, up 45.0% over the R$521.7 million in 4Q17. This increase is mainly explained by (i) the improvement in hydrological conditions in the last quarter of 2018 vs. 2017, the average GSF was 81.9% (vs. 69.3% in 4Q17) and the average PLD was R$158.24/MWh (vs. R$398.09/MWh in 4Q17); (ii) the decreased provisions and reversals (R$35.2 million provisioned in 4Q18 vs. R$268.4 million in 4Q17), mainly due to the reversal of civil and administrative lawsuits, totaling R$80.7 million, and to the 29.2% decrease in the provision for labor lawsuits; and (iii) a 6.1% increase in the volume of energy sold to final consumers, which increased the revenues from “electricity sales of customers”.

This growth was partially offset by (i) the 17.3% decrease in “electricity sales of distributors”, since TPP Araucária dispatched 195.2 GWh in 4Q17, while in 4Q18 there was no dispatch, and (ii) the 35.2% increase in “charge of the main distribution and transmission grid”, mainly reflecting the effect of CCEE’s decision in 4Q17 to transfer the surplus of resources accumulated in CONER to the market (affecting the ESS), as well as the higher costs with the use of the system - basic network, due to the TUST readjustment in June 2018 and the readjustment of Itaipu’s electric energy transmission tariff.

EBITDA was also impacted by non-recurring events, with a reversal of R$92.7 million related to an indemnification action against third parties on alleged losses caused by the implementation of a

hydroelectric project. Excluding the extraordinary effects, adjusted EBITDA in 4Q18 would be R$692.7 million, 0.6% higher than in the same period of the previous year, while in the last year accumulated R$3,086.3 million, growth of 9.8% compared to 2017.

Also, excluding the effects of the equity income, the adjusted EBITDA of 4Q18 would be R$681.9 million, an amount 6.3% above the R$641.2 million recorded in 4Q17. Already in the accumulated of the year would be R$2,950.4 million, an increase of 8.9%.

2.5 Financial Result

In 4Q18, the financial result was a negative R$137.6 million vs. the negative R$230.5 million in the 4Q17. The result reflects the 10.7% improvement in financial revenues, mainly due to the updating of the Cost Variation Account (CVA) and a 20.0% reduction in financial expenses, mainly due to the lower amount spent on “PIS/Pasep e Cofins on interest on equity” due to the lower interest on equity (IOC) received by Copel Holding from its subsidiaries.

These effects were partially offset by the lower income and monetary change on CRC transfers, due to the IGP-DI change in the period (-1.33% in 4Q18 vs. 1.65% in 4Q17).

As of December 31, 2014, Copel Distribuição has recognized sectorial financial assets and/or liabilities in its financial statements as a result of an amendment to the concession agreement, that guarantees that the residual amounts of items of Portion A and other financial components not recovered or returned via tariffs

Accounts Receivable Related to the Concession

This line refers to accounts receivable related to the contracts for the concession of electric power generation, transmission, distribution and distribution of natural gas activities. The amounts refer to (a) the concession fee paid as a result of the auction involving the Governador Parigot de Souza Power Plant – HPP GPS, won by Copel GeT on November 25, 2015 (R$625.8 million), (b) its investments in infrastructure and financial remuneration that have not been or will not be recovered via tariffs until the expiration of the concession (R$783.0 million), (c) the amounts receivable from energy transmission assets of the Existing System Basic Network – RBSE and connection facilities and other transmission facilities - RPC, as a result of the recognition of the effects of MME Ordinance No. 120 and the approval, by Aneel, of the result of the inspection of the appraisal report of these assets (R$753.8 million) and (d) the gas distribution concession agreement - Compagas (R$322.3 million) and (e) to the electricity generation concession contract due to the expiration of the concessions of the HPP GPS and HPP Mourão I (R$65.8 million). As of December 31, 2018, the balance of the account totaled R$2,550.7 million. More details in our Financial Statements (NE n ° 10).

Contract Assets

With CPC 47/IFRS 15 coming into effect on January 1, 2018 and bringing the concept of “contract assets” referring to the receipt rights conditioned to the compliance with obligations to operate and maintain the infrastructure and not only by the passage of time (concept “financial asset”), the Company changed the classification for agreement assets of the part related to assets of the concession of distribution of electric energy, distribution of piped gas and transmission of electric energy, now classifying as “contract assets” the construction works for distribution of electric energy and piped gas during the construction period (reclassification of ongoing intangible assets to contract assets) and changed the classification to contract assets of the part related to RBSE assets ratified for receipt after the first RAP cycle that started in July 2017.

On December 31, 2018, the account balance totaled R$3,433.2 million. More details in our Financial Statement (Note 11).

the following jointly controlled ventures: Costa Oeste, Marumbi, and Transmissora Sul Brasileira de Energia. Under this agreement, Copel GeT now holds a 100% interest in Costa Oeste and Marumbi, and Eletrosul holds a 100% interest in Transmissora Sul Brasileira, resulting in a classification change (R$36.7 million in Costa Oeste and R$92.3 million in Marumbi) and a write-off (R$65.5 million in Transmissora Sul Brasileira) of these investments. This result was partially offset by the increased equity income and contributions in the period.

Investments, Property, Plant and Equipment and Intangible Assets

The balance in ‘investments’ decreased by 7.4% by December 31, 2018, mainly due to the new CPCs, mainly CPC 47/IFRS 15 (Note 4.18.3), changing the classification of the balance of the financial asset of the jointly controlled ventures to contract asset, as of January 1, 2018, with a decrease in its measurement of R$200.6 million, as well as the Shares Exchange Agreement signed on August 30, 2018 by Copel GeT and Eletrosul in

The ‘Property, Plant and Equipment’ increased 10.3% due to the start-up of new assets, according to the Company’s investment program, net of depreciation for the period. The ‘Intangible’ decreased 6.6%, mainly because of the initial adoption of CPC 47/IFRS 15, as of January 1, 2018, with the balance of construction works in progress transferred to contract assets (Note 11.1).

4. Performance of the Main Companies

4.1 Copel Geração e Transmissão

Copel GeT recorded an EBITDA of R$512.2 million in 4Q18, 4.5 times higher than the R$114.7 million recorded in 4Q17. This result mainly reflects (a) the 85.1% decrease in the “electricity purchased for resale”, mainly due to (i) an improved hydrological scenario (GSF of 81.9% in 4Q18 vs. 69.3% in 4Q17) and the lower average PLD in the period (R$158.24/MWh in 4Q18 vs. R$398.09/MWh in 4Q17), and (ii) the lower volume of energy purchased in bilateral agreements; (b) a reversal of “provisions and reversals” of R$31.0 million (vs. R$185.1 million provisioned in 4Q17) due to the reversal of a provision for civil and administrative lawsuits totaling R$92.7 million, concerning a lawsuit for compensation to third parties for the implementation of a hydroelectric project, partially offset by a R$61.3 million impairment, of which R$58.3 million was provisioned at the Colíder plant, due to the postponement of the start-up of this plant; and (c) the effects of the tariff revision applied as of June 2017 to transmission companies in which Copel GeT has an interest, negatively impacting the equity pickup in 4Q17, over the positive effect of the tariff adjustment in June 2018.

These effects were partially offset by the 25.5% decrease in “use of the main distribution and transmission grid (TUST)” as a result of tariff readjustments and revisions and the 43.0% increase in “charges of the main distribution and transmission grid”, in accordance with the provision of charges of network transmission made available to the Colíder HPP.

In addition, manageable costs, ex-estimated losses, provisions and reversals, and water use fees decreased by 14.1% and basically reflect the reversal of R$9.0 million related to the employees who gave up on leaving the company by PDI.

Disregarding the effect of the provision for indemnification related to PDI (reversal of R$9.0 million in 4Q18 and provision of R$8.6 million in 4Q17), personnel costs increased 2.7% vs. 4Q17, remaining below the accumulated inflation of 3.7% in the last 12 months.

Net profit was of R$310.8 million in 4Q18, 3.8 times higher than the R$80.8 million recorded in 4Q17.

Copel GeT’s EBITDA increased by 14.8% in 2018, mainly due to the growth of 168.2% in income from equity accounting in the face of the effects of the tariff revision applied, as of June 2017, to transmission companies in which Copel GeT holds an interest, negatively impacting the equity income in 2017, due to the positive effect of the tariff adjustment in June 2018. Also noteworthy is the decreased ‘provisions and reversals’ in 2018.

Excluding the extraordinary effects listed below, Copel GeT’s EBITDA increased by 41.0% in 4Q18 and by 9.0% in 2018.

4.2 Copel Distribuição

Copel Distribuição reported an EBITDA of R$175.9 million in 4Q18, up 58.6% over the R$110.9 million verified in 4Q17, mainly due to the 16.42% increase in TUSD, effective as of June 24, 2018, which, in line with the 1.8% growth in the grid market, contributed to the 2.6% increase in “use of the main distribution and transmission grid”.

In addition, manageable costs, excluding credit losses, provisions and reversals, decreased 6.8% vs. 4Q17, mainly due to (i) the decrease of 7.3% in personnel and management costs, due to the reversal of provision

of R$8.0 million related to employees who declined the PDI, partially offset by the salary adjustment of October 2018, (ii) savings in communication, processing and data transmission costs, affecting “third-party services”, and (iii) a 18.3% decrease in “material”, basically related to lower expenses with fuel and parts for vehicles.

Disregarding the effect of the provision for indemnification related to PDI (reversal of R$8.0 million in 4Q18 and provision of R$12.2 million in 4Q17), personnel costs remained basically the same YoY, with an increase of only 0.3%. During this period, accumulated inflation was of 3.7% and salary adjustments were of 3.97% made in October 2018, thus, there was an actual decrease of costs, in line with the decrease in the number of employees. In the last 12 months, there was a reduction of 382 employees at Copel Distribuição.

Also noteworthy was the 22.7% decrease in “provisions and reversals”, basically due to the lower amounts provided for labor lawsuits in 4Q18.

Net profit in 4Q18 was of R$126.7 million, 96.0% higher than the R$64.7 million recorded in 4Q17.

In 2018, Copel Distribuição recorded an EBITDA of R$799.5 million, a 39.5% bigher than 2017. This performance was mainly impacted by tariff adjustment of the distributor and the effort to reduce manageable costs. This improvement was partially offset by the 18.8% increase in provisions, as a result of labor claims collective.

Excluding the extraordinary effects listed below, Copel Distribuição's EBITDA would be R$176.7 million in 4Q18, 14.1% higher than the R$154.9 million reported in 4Q17 . In 2018, EBITDA would be R$893.1 million, 34.2% higher than in 2017 (R$665.7 million).

Compared EBITDA reported with regulatory EBITDA (R$1.0 billion), the performance was 23.4% down, due to manageable costs are above the tariff coverage. The following are highlighted: PECLD of R$22.9 million above the tariff coverage and accounting R$83.8 million in collective labor lawsuits and R$41.6 million with provisions for the PDI.

Excluding these effects, adjusted EBITDA would be of R$893.1 million, 16.8% lower than the regulatory.

It should be noted that the efforts to reduce the gap between regulatory and actual EBITDA have shown results: the gap decreased from 86% in 2016 to 23% in 2018.

4.3 Copel Telecomunicações

Copel Telecom recorded a negative EBITDA of R$4.2 million in 4Q18. This reflects mainly the provision of R$36.0 million referring to the deactivation of equipment infrastructure in Copel Telecom’s customers throughout the year, partially offset by reduction of 34.7% in the "personal and administrators. "

In view of the effects of the above mentioned the manageable costs, excluding others provisions and reversals, totaled R$99.4 million in 4Q18, growth of 36.2% in relation to 4Q17.

Disregarding the effect of the provision for indemnification related to the PDI, personnel and administrative costs declined by 24.3% compared to 4Q17 and basically reflect the wage policy applied from October 2017 and the reduction of workforce due to internal restructuring, with the transfer of 137 employees to other subsidiaries and of the PDI. The workforce was reduced by of 171 employees in the last 12 months.

Excluding extraordinary events, Copel Telecom's EBITDA in 4T18 was negative at R$6.2 million, compared to the positive R$25.9 million recorded in 4Q17.

In 4Q18 Copel Telecom recorded a loss of R$12.3 million, basically due to the provision for deactivation of equipment infrastructure of customers in 2018.

The following table presents the main indicators of Copel Telecom:

Copel Telecom's EBITDA in 2018 reached R$110.4 million, down 17.4% compared to the performance recorded in 2017. While net income fell 54.8%, totaling R$24.4 million.

In addition, Copel GeT operates one plants under the quota system, as shown below:

Copel was designated as the provisional operator of the Rio dos Patos plant (1.7 MW of installed capacity and assured power of 1MW average) after the final term of the concession. However, its operation was suspended in September 2014 due to flood damage in June of that year.

On July 5, 2018, the ANEEL through Authorization Resolution No. 7.050 of June 5, 2018 extinguished the concession of the plant without the reversion of the assets to the granting authority, considered unfeasible to the continuity of the service and therefore, freely available to Copel GeT, being the company responsible by demobilization and eventual disposal of the assets.

On December 11, 2018, the Company signed the promissory instrument for the purchase and sale of the remaining assets of the extinguished Rio dos Patos plant, with Dois Saltos Empreendimentos de Geração de Energia Elétrica Ltda., under the terms of Authorizing Resolution No. 7050 of June 5, 2018 of Aneel.

Wind Farms Complex

Under Construction

Copel Geração e Transmissão

Copel GeT is building two hydroelectric plants that will add a total of 405 MW of installed capacity to its generating plant. As of March 28, 2019, the Colíder HPP had a generating unit operating commercially, while the UHE Baixo Iguaçu had two units in operation since February 2019.

In addition of Colíder HPP and Baixo Iguaçu HPP, in August 2018 Copel conquered the right to build Bela Vista SHP (29 MW of installed capacity) predicting the start of works for the first quarter of 2019.

Colíder Hydroelectric Power Plant

On July 30, 2010, under Aneel New Energy Auction no. 003/2010, Copel GeT was awarded the concession to explore the Colíder HPP for a term of 35 years, from January 17, 2011, the signing date of MME - Colíder HPP Concession Agreement no. 001/11.

The project will be made of a main power house with an installed capacity of 300 MW, sufficient to serve around 1 million inhabitants, based on the estimated energy potential of the Teles Pires River on the border of the municipalities of Nova Canaã do Norte and Itaúba, in northern of State of Mato Grosso.

The BNDES endorsed the qualification of the Colíder HPP for feasibility analysis of financial support and the financing agreement, in the amount of R$1,041.2 million. The amounts released up to December 31, 2018 total R$1,005.1 million.

Due to force majeure events and government acts, such as fire in the construction site, difficulties related to environmental licensing, supplier delays in equipment delivery and services related to electromechanical assembly services and the construction of the transmission line associated to the plant, the project suffered impacts on its schedule, so that the commercial generation of the plant was delayed, with the first generating unit started the commercial operation in March 2019, and the other units are scheduled to start until May 2019. As a result of these events, there is recorded for this project a balance of estimated losses due to impairment of the asset in the amount of R$731.3 million on December 31, 2018 against R$683.0 million on December 31, 2017. Due to the postponement of the start of operation of the first turbine for March 2019 (in 2017 considered May 2018), and changes in the budget of the work, an additional provision was recognized.

The energy from the Colíder HPP was sold at an Aneel auction at a final tariff of R$103.40/MWh, as of July 1, 2010, restated by the IPCA inflation index to R$169.52 on December 31, 2018. A total of 125 average-MW was traded, to be supplied beginning January 2015, for 30 years. Copel GeT filed with Aneel a request for exclusion of liability, so that the obligation to supply the energy sold is postponed. The request was not

accepted in first instance; however, the Company exercised its right to appeal and filed a motion for rehearing, which was denied on March 14, 2017. As Copel GeT does not agree with the decision, it filed another motion for rehearing, which was denied on a final basis on July 4, 2017. Not agreeing with the decision, Copel GeT again requested the reconsideration, which was definitively denied on July 4, 2017. Copel GeT filed on December 18, 2017 an ordinary action with the Judicial Court requesting the reversal of the agency's decision and on April 6, 2018, the Federal Court of the 1st Region fully granted the advance notice of appeal required by Copel GeT in the Instrument of Appeal to exempt it from any liens, charges or restrictions due to the displacement of the schedule of implementation of the HPP Colíder.

Copel GeT has been honoring energy supply agreements as follows:

• from January 2015 to May 2016: with energy surplus of its other plants that has not been contracted;

• In June 2016: partial reduction through Bilateral Agreement

• from July 2016 to December 2018: with a reduction of all Energy Commercialization Agreements in the Regulated Environment - CCEARs, through a Bilateral Agreement and participation in the New Energy MCSD.

The assured power of 177.9 average MW of the plant, established by Ordinance MME nº 258, on December 21, 2016, was increased to 178.1 average MW, according to MME Ordinance No. 213 / SPC, of July 14 2017.

Baixo Iguaçu Hydroelectric Power Plant

Copel holds a 30% interest in the Consórcio Baixo Iguaçu (CEBI). The purpose of the consortium is to build and operate the HPP Baixo Iguaçu, with an installed capacity of 350.2 MW and assured power of 171.3 average-MW located on the Iguaçu river, between the cities of Capanema and Capitão Leônidas Marques, and between HPP Governador José Richa and the Iguaçu National Park, in the State of Paraná. With an estimated total investment of R$2.5 billion, the commercial generation of units 1 and 2 began in February 2019 and unit 3 is scheduled for March 2019.

Work on the construction site began in July 2013, with the excavation of the generation circuit, the earthworks of the construction site and the construction of the housing areas. The original schedule was changed due to the suspension of the Installation License, according to the ruling of the Regional Federal Court of the 4th Region (TRF-RS), which occurred on June 16, 2014, and paralyzed the construction works from July of that year. In March 2015, a ruling authorizing the resumption of the construction works was issued. However, the Chico Mendes Institute for Biodiversity Conservation (ICMBio) enforced additional constraints on the environmental licensing, which prevented the immediate resumption of the construction work. CEBI submitted to the Environmental Institute of Paraná (IAP) all the necessary information to comply

with these constraints and, in August 2015, the license was issued. After the measures discussed and agreed with the Developer Consortium, on February 1, 2016, the construction work was fully resumed.

In August 2016, Aneel issued the 2nd Amendment to the Concession Agreement, in order to formalize the redefinition of HPP Baixo Iguaçu’s schedule, as well as its final closing date, acknowledging, in favor of CEBI, an exemption of liability for the delay in the implementation of the project for a period corresponding to 756 days, recommending to the MME the extension of the term of the grant and establishing that the CCEE must postpone the beginning of the supply period of the CCEARs for the period of the recognized exemption of liability.

On November 7, 2017, Aneel recognized an additional 46 days of exclusion of liability for the delay in the implementation of the Baixo Iguaçu HPP, barring any penalties and contractual, commercial or regulatory obligations arising from the delay. The project already had 746 days of exclusion of liability; therefore, its concession term will now expire on October 30, 2049 and supply of the Energy Commecialization Agreements shall begin on November 12, 2018.

On December 18, 2018, the filling of the reservoir was completed, which enabled the start of the commercial operation of the first two generating units in February 2019.

Wind Farm Complex

Copel is expanding its energy generation matrix with renewable sources by building wind farm complexes in the State of Rio Grande do Norte, consisting of 13 projects with a total installed capacity estimated at 312.9 MW, as follows:

Currently 95% of the 149 wind turbines are in operation (127 in commercial operation and 16 in tests), and the remaining 6 wind turbines will enter in a staggered way.

The Copel wind farm named Cutia and is divided into two large complexes:

• Cutia Complex: composed of seven wind farms (Guajiru, Jangada, Potiguar, Cutia, Maria Helena, Esperança do Nordeste and Paraíso do Ventos do Nordeste) with 180.6 MW of total installed capacity, 71.4 average MW of assured power, all located in the State of Rio Grande do Norte. The power that will be generated by the farms was sold on the 6th Reserve Auction that was held on October 31, 2014, at an average historical price of R$144.00/MWh updated by the variation of the IPCA to R$183.26 in December 31, 2018. Starting in the last fortnight of December 2018, the wind farms started the commercial operation in a stepped way by aerogenerator; and

• Bento Miguel Complex: composed of six wind farms (São Bento do Norte I, São Bento do Norte II, São Bento do Norte III, São Miguel I, São Miguel II and São Miguel III) with a total installed capacity of 132.3 MW, 58.1 average MW assured power, all also located in the State of Rio Grande do Norte. The power that will be generated by the farms was sold on the 20th New Energy Auction that was held on November 28, 2014, at an average historical price of R$136.97/MWh, updated by the variation of the IPCA to R$179.84 in December 31, 2018. As of January 29, 2019, wind farms began to operate commercially in a staggered form by aerogenerator.

Due to the reviewed impairment in these projects, the balance of estimated losses due to asset impairment were of R$252.5 million on December 31, 2018 (R$167.9 million for Cutia and R$84.6 million for Bento Miguel), over R$322.7 million on December 31, 2017. The reversal of R$70.2 million (R$56.6 million and R$13.6 million for Cutia and Bento Miguel, respectively), observed in both complexes is justified by the increase in the generation estimate, changed to 100% of the P-50 physical guarantee (in 2017, 95% of P-50) and by the changes in the long-term forecast of LDP and the selling price in ACL.

8.2 Transmission

Assets in Operation

The chart below shows the transmission concession agreements and the design of the substations park and the transmission lines in operation:

On August 30, 2018, Copel GeT concluded a Swap Contract of Shares with Eletrosul in the jointly-controlled developments of Costa Oeste Transmissora de Energia SA (51% Copel GeT and 49% Eletrosul), Marumbi Transmissora de Energia SA (80% Copel GeT and 20% Eletrosul) and Transmissora Sul Brasileira de Energia SA (20% Copel GeT and 80% Eletrosul). Under this agreement, Copel GeT now holds 100% interest in the Costa Oeste and Marumbi projects, while Eletrosul now holds a 100% stake in Transmissora Sul Brasileira.

The assumption of 100% of the Costa Oeste and Marumbi's participation in Copel GeT will allow the appropriation of scale gains in the integrated management of these projects with the company's other assets. Business combinations occurred on August 31, 2018, the date of the transfer of shares. More details are in note 1.2 of our DF.

Assets under Construction

Copel GeT is substantially increasing its share of the transmission segment through own investments and partnerships in SPCs. The projects have a joint total of 1,074 km of transmission lines and 4 substations and will generate RAP of R$234.9 million of which refers to Copel Get stake. Copel’s interest in the transmission projects is available in the table below.

SPC Mata de Santa Genebra

On February 25, 2019, all the stages planned for the test run period of the Santa Bárbara d’Oeste substation, belonging to the SPC Mata de Santa Genebra, allowing the operation of this substation under the Commercial Operation regime.

The SPC Mata de Santa Genebra is still awaiting the issue of the Temporary Release Document (TLP - Termo de Liberação Provisória) by the ONS, without prejudice to the Commercial Operation date . The TLP will allow the SPC Mata de Santa Genebra to receive a portion of the Annual Permitted Revenue (APR) related to the Santa Bárbara d’Oeste substation, in the amount of R$10.8 million. The project’s total expected APR is R$233.8 million, of which R$117.1 million related to COPEL's stake, and full receipt is subject to the startup of the other stages of the project, which will enter step by step.

8.3 Distribution

Concession agreement

In December 2015, the Company signed the fifth amendment to the Public Electricity Distribution Concession Agreement no. 46/1999 of Copel Distribuição S.A., extending the concession term to July 7, 2045.

breach of quality criteria for three consecutive years or economic and financial management criteria for two consecutive years will result in the opening of a forfeiture process.

The concession agreement imposes economic and financial efficiency and quality conditions. Failure to comply with the conditions for two consecutive years or any of the limits at the end of the first five years will result in the termination of the concession. From the sixth year following execution of the agreement, any

The following chart shows the goals set for Copel Distribuição in the first 5 years of renovation:

Operating Data

In the distribution business, Copel serves more than 4.6 million energy customers in 1,113 locations, belonging to 394 municipalities in State of Paraná and one in the State of Santa Catarina. Copel Distribuição operates and maintains the installations in the 13.8 kV, 34.5 kV, 69 kV and 138 kV.

Compact-Design Distribution Lines

Copel Distribuição has continued to implement compact-design distribution lines in urban areas with a high concentration of trees surrounding the distribution grids. This technology reduces the number of trees cut down or trimmed, and improves the quality of power supply by reducing the number of unplanned outages. In December 2018, the total length of compact-design distribution lines in operation was 10,477 km.

Secondary Isolated Lines

Copel Distribuição has also invested in low-voltage (127/220V) secondary isolated lines, which offer substantial advantages over regular overhead lines, including: improvement in DEC and FEC distribution performance indicators, defense against illegal connections, improved environmental conditions, reduced

areas subject to tree trimming, improved safety, reduced voltage drops throughout the grid, and increased transformer useful life, due to the reduction of short-circuits, among other advantages. The total length of installed secondary isolated lines closed December 2018 at 18,255 km.

Quality of Supply

The two main indicators of power supply quality are DEC (outage duration) and FEC (outage frequency). The trends for these indicators, as well as for total time service, are shown below:

8.4 Telecommunications

Copel Telecomunicações has an optical backbone, a high capacity intermunicipal transmission network, and the access, a customer service network. The access network can be multi-point (GPON) or point-to-point (conventional), thus connecting the customer to the network's data transmission Copel Telecom and providing the contracted services.

In December 2018, the backbone cable network was 34.2 thousand km, carrying data in ultra-speed and managing an optical ring that serves the 399 municipalities of Paraná, with a portfolio of data, voice and datacenter products.

8.6 New Projects

Project Portfolio

Copel holds interests in different power generation projects. <0When these projects go into commercial operation, they will add 343.4 MW of installed capacity to the Company's portfolio.

Copel, in partnership with others companies is also developing studies in the lower reaches of the Chopim river that will lead to the feasibility of another hydroelectric projects. As for wind power generation, there are studies for the feasibility of new wind farms in the State of Rio Grande do Norte, where Copel already has wind assets. The short-term objective is to register such projects in the EPE to enable participation in the upcoming auctions to be organized by the Federal Government. The technical characteristics may be adjusted until the effective energy commercialization of the projects, since Copel's engineering is conducting optimization studies, in order to make the projects more competitive.

<0}Interest in Feasibility Study

Hydroelectric Potential Surveyed Along the Piquiri River

The feasibility studies for the four hydroelectric power plants making up the hydroelectric potential of the Piquiri River, in Paraná, were submitted by Copel GeT and accepted by Aneel in 2012. The projects are in the process of environmental licensing with the Environmental Institute of Paraná. The following table features these plants, which have a joint installed capacity 459.3 MW:

Gas Exploration and Production (Paraná Gás Exploração e Produção S.A)
On November 28, 2013, in the 12th round of Bids of the National Petroleum Agency (ANP), the consortium formed by Copel (30%), Bayar Participações (30%), Tucumann Engenharia (10%) and Petra Energia (30%) (the latter acting as operator) won the right to explore, develop and produce natural gas in four blocks in an 11,327 km² area in the midwestern region of the State of Paraná. The consortium’s total investment will come to R$78.1 million in the first phase of exploration, for the terms of four years granted by the ANP. Copel and its partners Bayar, Tucumann and Petra signed concession contracts for 2 blocks in May 2014. At the end of 2016, State Law No. 18.947/2016 was sanctioned, suspending por ten years the environmental licensing of any drilling or exploration activity of shale gas by the hydraulic fracturing method, better known as "fracking".
Due to the ruling rendered regarding the Public Civil Action referred to above (in the lower court), issued on June 7, 2017, stating the nullity of the bidding procedure and the respective agreements signed for the areas of the Rio Paraná Basin, and the lack of compliance prospects of the object of ANP’s 12th Round of Bids, the consortium resolved to request to ANP the discharge from its contractual obligations under the 12th Round of Bids without charges to the bidders, with the consequent refund of the signature bonus, reimbursement of the guarantee costs incurred and discharge of the guarantees presented (application filed at ANP on June 6, 2017).
