Investor Relations Officer.

Re: Request for clarification on a news article

Dear Officer,

| 1. | In response to the news article published electronically by “Isto É Online”, in its business section on March 27, 2023, under the headline: “Cemig is getting ready to be privatized and seeks to advance this agenda before the Government,” containing the following statements made by company executives: “CEMIG, a company based in the state of Minas Gerais, is getting ready for its potential privatization, with initiatives to make it more efficient and profitable, as it works to convince the Minas Gerais State Government to urgently move forward with this agenda at the Minas Gerais State Legislative Assembly.” At a public meeting with investors and analysts this Monday, Reynaldo Passanezi, the CEO of CEMIG, and Márcio Utsch, chair of the board of directors, defended that the Minas Gerais State Government be immediately mobilized to work on the company’s privatization agenda, which still needs to be approved at the State Legislative Assembly. According to Mr. Utsch, strategic changes made in recent years, such as divestments of minority stakes in companies like Light and Renova, allowed them to ‘clear up’ CEMIG management’s agenda, opening up the way so they could dedicate more time to the privatization. “We gradually cleared up items on the agenda so that we could increasingly focus on the state of Minas Gerais, selling assets with low or even negative profitability, allowing us to focus on privatizing the company,” he added. The chair of the board of directors of CEMIG sees a more favorable scenario for the legislative approval of the privatization, being said approval likely to be granted ‘on this mandate.’ He also stated that CEMIG’s management defends that the Minas Gerais State Government immediately mobilizes the State Legislative Assembly to approve the privatization.

| 2. | In view of the above, we request that you clarify whether the news article is true and, if so, explain the reasons why you believe that it is not a material fact, and comment on other information deemed as important on the matter.

| 3. | It is worth noting that according to article 3 of CVM Resolution 44/21, the Investor Relations Officer is responsible for disclosing and informing the CVM and, if applicable, the stock exchange and the organized over-the-counter market entity where the Company’s securities are traded, of any material act or fact occurred or related to its business, as well as for ensuring its wide and immediate communication, simultaneously in all the markets in which such securities are traded.

CEMIG’s Response

Dear Nilza Maria Silva de Oliveira,

In response to Official Letter 93/2023/CVM/SEP/GEA-1 of March 28, 2023, Companhia Energética de Minas Gerais - CEMIG (“Cemig” or “Company”) clarifies that:

The news article published in the business section of the Isto É Online website, under the headline: “Cemig is getting ready to be privatized and seeks to advance this agenda before the Government” alludes to the 28th edition of Meeting with Investors, organized by the Company on March 27, 2023. The comments involved public explanations, in response to the market, on the Company’s major strategic direction.

It is worth noting that the topic of the news article involves an interest that has been publicly expressed on multiple occasions by the Governor of Minas Gerais State, representing the Company’s controller, i.e. the Minas Gerais State, in privatizing CEMIG.

In this sense, please check out news published during the Minas Gerais State Elections in 2018 (https://epbr.com.br/privatizacao-da-cemig-na-pauta-de-zema/) and 2022 (https://economia.uol.com.br/noticias/reuters/2022/12/28/governo-de-mg-considera-privatizar-cemig-em-modelo-de-corporation-diz-valor.htm), and (https://www.suno.com.br/noticias/cemig-cmig4-zema-privatizacao/). For this reason, there is no new act or fact leading the Company to formally disclose a material fact in this regard, even because the Company’s shareholders did not resolve on the Company’s potential privatization.

It is also worth noting that the measures required to change CEMIG’s controlling interest depend on the approval from the controlling shareholder and other agents, as per the Minas Gerais State Law.

The Company states that there is no new information to date, according to CVM Resolution 44/21, to justify the disclosure of a Material Act or Fact about the matter.

The Company reiterates its commitment to transparency and the best market disclosure practices.

Distribution and consumption, by sector

Industrial clients accounted for 47.3% of Cemig D’s total distribution. The greater part was energy transported for industrial Free Clients (44.4%), which was 3.8% higher in volume than in 1Q22. Volume of energy billed to captive clients was 2.9% of the total distributed, and 9.4% less than in 1Q22 – mainly due to migration of clients to the Free Market.

Residential consumption was 25.9% of total energy distributed by Cemig D, and 5.0% higher than in 1Q22. Average monthly consumption per consumer in the quarter was 2.2% higher than in 1Q22, with the number of clients 2.8% higher (an increase of 204,900 clients in 12 months), partly due to migration of 23,200 consumers from the Rural category in compliance with Aneel Resolution 1000/2020.

COMPANHIA ENERGÉTICA DE MINAS GERAIS S.A. | 10 |

Table of Contents

Commercial and services: Volume distributed to these consumers was 14.0% of the total distributed by Cemig D in 1Q23, and by volume 1.9% more than in 1Q22. This increase comprises a reduction of 3.0% in the volume of energy billed to captive clients, and an increase of 14.9% in the volume transported for Free Clients.

The number of Cemig consumers in the Free Market increase by 17.6% YoY – the effect of migration of captive clients. As well as this migration, the migration of consumers to the Micro- and Mini- Distributed Generation market contributed to the reduction of the captive market.

Rural clients consumed 4.6% of the total energy distributed in 1Q23: by volume, 4.5% less than in 1Q22, as a result of the number of consumers in the category being 8.8% lower (reduction of 44,000 clients) - due to reclassification to other categories as required by Aneel Normative Resolutions 901/2020 and 1000/2020.

Public services: The volume distributed to this category was 7.6% of the total energy distributed, with consumption 4.9% higher than in 1Q22, mainly reflecting an increase of 2.6% in the number of consumer units.

The annual tariff adjustment

Cemig D’s tariffs are adjusted in May of each year. Every five years there is the Periodic Tariff Review, also in May. The aim of the Tariff Adjustment is to pass on changes in non-manageable costs in full to the client, and to provide inflation adjustment for the manageable costs that are established in the Tariff Review. Manageable costs are adjusted by the IPCA inflation index, less a deduction factor known as the ‘X Factor’, under a system using a price-cap regulatory model.

On June 22, 2022, after an extension of the previous tariffs by 25 days, Aneel ratified the result of Cemig D’s annual tariff adjustment, in effect until May 27, 2023, in which the average effect perceived by consumers was an increase of 8.80%. For residential consumers served at low voltage, the average increase was 5.22%. The difference in revenues arising from the postponement of the increase will be adjusted by the Selic basic interest rate, and compensated for in the tariff adjustment event of 2023. An amount of R$ 2.81 billion was included in the 2022 tariff adjustment process referring to the reimbursement of PIS, Pasep and Cofins taxes, representing a negative variation in the tariff of 15.20%.

Average effects of the Tariff Adjustment
High Voltage | 14.31%
Low voltage | 6.23%
Average effect | 8.80%

The result of the Periodic Tariff Review of Cemig D (which takes place every 5 years) will come into effect on May 28, 2023 – this process is currently under assessment by Aneel.

Quality indicators – DEC and FEC

The DEC indicator of average outage time per consumer (Duração Equivalente de Interrupções por Consumidor) was 9.74 hours in the moving window up to March 2023. Despite the more challenging target for the year 2023 (9.58 hours), the Company is working and investing heavily in the distribution business to provide quality service to our customers and meet the regulatory parameter.

Combating default

Cemig has maintained its high level of collection actions, achieving greater efficiency in combating default.

A good indication of this is the Billing Collection Index (‘ARFA’) posting 99.75% at the end of 1Q23 – boosted in part by growing migration of receipt of payments to digital media.

In combating default, we highlight the following activities:

| § | New payment channels, and online negotiation, made available in recent quarters, have contributed to increase in the volume of collection via digital channels (PIX instant payments, automatic debits, payments by card and app, etc.) to approximately 59.64% of the total collected – compared to 53.97% in 1Q22. Payments by PIX, for example, were 12.4% of the total collected in 1Q23. This change in the collection mix reduced costs by 10.0% – a saving of R$ 2 million.

| § | Cemig now accepts payment of overdue electricity bills by credit card – transferring the risk of receipt to the card operator.

Energy losses

Energy losses were compliant with the regulatory level in the 12 months, at 11.06% (the regulatory level is 11.22%).

Among actions to combat losses, in 1Q23: (i) We made 119,000 client inspections; (ii) 97,000 obsolete meters were replaced; (iii) 6,000 conventional meters were replaced by smart meters; and (iv) 1,900 clandestine connections were regularized. In another highlight, inspections with positive results were approximately 50% of the total.

Cemig GT / Holding Company

Electricity market

The total volume of electricity sold by Cemig GT and by the Cemig holding company (‘Cemig H’), excluding sales on the wholesale power exchange (CCEE) was 7.2% higher than in 1Q22. Cemig GT sold 6,332 GWh (including quota sales) in 1Q23, 15.5% less than in 1Q22. This reduction reflects transfer of sales contracts totaling 2,998 GWh (excluding CCEE transactions) to Cemig H. These especially include contracts for sales to traders, accounting for the reduction of 26.2% in that category.

Cemig Holding posted sales of 2,998 GWh in 1Q23. Migration of contracts from Cemig GT to Cemig Holding began in 3Q21 (in that quarter the only revenue posted was from settlements in the CCEE), and has been growing gradually since then.

Gasmig

Gasmig is the exclusive distributor of piped natural gas for the whole of the state of Minas Gerais. It serves industrial, commercial and residential users, and users of compressed natural gas and vehicle natural gas; and supplies gas as fuel for thermoelectric generation plants. Its concession expires in January 2053. Cemig owns 99.57% of Gasmig.

Gasmig’s tariff review process was completed in April 2022. The result of the review was an average reduction of 10.05% in the tariffs. Important aspects include the following:

| § | The WACC used (real, after taxes) was reduced from 10.02% p.a. to 8.71% p.a.

| § | Regulatory Ebitda for 2022 was approximately R$ 620 million.

| § | The Net Remuneration Base was increased significantly, to R$ 3.48 billion.

| § | The regulator recognized the cost of PMSO in full.

In 1Q23 the volume of gas sold by Gasmig was 2.5% lower than in 1Q22 (10.0% lower, including Free Market volume), due to zero dispatching of the thermal generation plants in 1Q23. Meanwhile, year-on-year, consumption by commercial users was down 6.5%, and industrial consumption was up 17.4% (up approximately 5.8%, if Free Market volume is included). Excluding the thermoelectric generation market, total sales volume was 14.0% higher (and approximately 4% higher including the Free Market).

The number of Gasmig’s clients increased by 14.6% from 1Q22, to a total of 84,720 in 1Q23. This growth reflects expansion of the residential client base (addition of 10,700 clients).

Consolidated volume of energy sold: up 4.3% YoY GWh

Energy sold to final consumers

Gross revenue from sales to final consumers in 1Q23 was R$ 6,189.6 million, compared to R$ 7,413.5 million in 1Q22, a reduction of 16.5% YoY, in spite of volume being 2.6% higher. The lower figure is mainly explained by the lower rate of ICMS tax, which was limited to 18% as from the second half of 2022, by Law 194 of 2022.

Wholesale

Revenue from wholesale supply in 1Q23 was R$ 905.7 million, compared to R$ 890.5 million In 1Q22 – and increase in volume of 9.1 – due to higher spot sales to traders in 1Q23, and new sales contracts with supply start dates as from January 2023.

The expense on electricity bought for resale in 1Q23 was R$ 3.44 billion, which was R$ 340.7 million, or 11.0%, higher than in 1Q22. This arises mainly from the following items:

COMPANHIA ENERGÉTICA DE MINAS GERAIS S.A. | 19 |

Table of Contents

| § | Expenses on energy acquired in the Regulated Market were 49.8% higher than in 1Q23. This increase is due to lower energy costs in 2022.

| § | Expenses on supply from Distributed Generation were 36.4% higher than in 1Q22, arising from the increase in the number of distributed generation plants installed, and the higher quantity of energy injected into the grid (1,020 GWh in 1Q23, vs. 669 GWh in 1Q22).

| § | The expense on energy bought from Itaipu was 33.5% lower, due to reduction of its price from U$24.73/kW to U$16.19/kW;

| § | The costs of energy acquired in the Free Market, which are the Company’s highest costs of purchase of energy, were R$ 1.22 billion, practically stable (down 0.4%) YoY, in spite of the higher volume of energy purchased for resale.

| § | The cost of physical guarantee quota contracts was 5.4% higher, due to the annual increase in the Annual Generation Revenues (RAG – Receita Anual de Geração) of the plants operating under the quota regime, which is set by a Resolution, always in July.

Note that for Cemig D, purchased energy is a non-manageable cost: the difference between the amounts used as a reference for calculation of tariffs and the costs actually incurred is compensated for in the subsequent tariff adjustment.

Charges for use of the transmission network and other system charges

Charges for use of the transmission network in 1Q23 totaled R$ 700.2 million, 19.4% less than in 1Q22. The lower figure is mainly due to the almost complete elimination of costs on the System Services Charge, due to the lower level of dispatching of plants outside the merit order. This is a non-manageable cost in the distribution business: the difference between the amounts used as a reference for calculation of tariffs and the costs actually incurred is compensated for in the subsequent tariff adjustment.

Gas purchased for resale

The expense on acquisition of gas in 1Q23 was R$ 614.8 million, or 9.0% higher than in 1Q22. This reflects the increases in the price of gas over the 12-month period.

Outsourced services

Total expenses on outsourced services were 23.1% higher than in 1Q22, the main factors being: (i) expenses on maintenance and conservation of facilities and equipment R$ 33.0 million (23.1%) higher; and (ii) expenses on IT R$ 7.5 million (16.9%)higher; and (iii) R$7.2 million higher in consumer unit inspection.

Provisions for client default

The provision for expected losses in 1Q23 was R$ 7.9 million, compared to R$ 43.1 million in 1Q22, mainly due to (a) a change in the measurement of these potential losses, put in place in the second half of 2022 (but still with impact in 1Q23), so as to be more compatible with the actual performance of default by the Company’s clients in practice; and (ii) an increase in settlement of regular debts by clients.

Impairment

An impairment of R$ 46.1 million was posted in 1Q23, recognizing a reduction in the recoverable value of the plants of Cemig GT that are in the process of sale. These plants – 15 Small Hydro Plants (PCHs) and Hydroelectric Generating Units (CGHs) – will be offered as a single unit in an auction scheduled to be held on August 10, 2023.

Post-retirement obligations

The impact of the Company’s post-retirement obligations on operational profit in 1Q23 was an expense of R$ 103.0 million, compared to an expense of R$ 153.5 million in 2022. The lower figure is due to remeasurement of the post-employment liability, in 1Q23, providing an accounting gain of R$ 56.9 million, reflecting the new health plan being accepted by part of the active employees.

People

The expense on personnel in 1Q23 was R$ 335.2 million, 10.4% higher than in1Q22, mainly reflecting the 6.46% increase in salaries under the Collective Work Agreement as from November 2022.

It comprises: Net profit adjusted for the effects of: (i) Net finance income (expenses), (ii) Depreciation and amortization, and (iii) Income tax and the Social Contribution tax. Ebitda is not a measure recognized by Brazilian GAAP nor by IFRS; it does not have a standard meaning; and it may be non-comparable with measures with similar titles provided by other companies. Cemig publishes Ebitda because it uses it to measure its own performance. Ebitda should not be considered in isolation or as a substitute for net profit or operational profit, nor as an indicator of operational performance or cash flow, nor to measure liquidity nor the capacity for payment of debt. (2) The Company adjusts the Ebitda calculated in accordance with CVM Instruction 156/2022, to exclude ite m s which, by their nature, do not contribute to information on the potential for gross cash flow generation since they are extraordinary items.
