*Excluding compensated energy from DG

Energy supplied to captive clients plus energy transported for Free Clients and distributors in 3Q24 totaled 12,378 GWh, or 4.5% more than in 3Q23 (excluding compensated energy from DG), mainly reflecting higher consumption by: residential clients ( – up 177.2 GWh or +6.2%); industrial clients ( – up 314.3 GWh or +5.6%); and rural clients ( – up 56.0 GWh or +6.4%). These increases were mainly due to: higher temperatures; higher economic activity; and higher demand for irrigation, in the period.

The growth of 4.5% in total energy distributed comprises: an increase of 8.6% ( +521.9 GWh) in use of the network by Free Clients, and an increase of 0.2% (+8.9 GWh) in consumption by the captive market.

Performance by sector

Industrial: Energy distributed to Industrial clients was 5.6% higher YoY in 3Q24, on higher physical production by industry, and was 48.2% of Cemig D’s total distribution. The greater part was energy transported for industrial Free Clients (46.0%), which was 6.8% higher by volume than in 3Q23. Energy billed to captive industrial clients was 2.2% of the total distributed, and 15.5% less by volume than in 3Q23 – mainly due to migration of clients to the Free Market. Highlights in industry by sector were: Increased consumption in Metallic production (+9.7), Ferroalloys (+13.4%), Foods and beverages (+4.8%) and Chemicals (+7.1%). The only sector with significantly lower power consumption, YoY, was Non-ferrous metals (–7.0%).

Residential: Residential consumption was 24.7% of total energy distributed by Cemig D, and 6.2% higher than in 3Q23. Average monthly consumption per consumer in the quarter, at 128.8 kWh/month, was 3.1% higher than in 3Q23, reflecting temperatures higher than the historic averages, and higher family consumption. Also contributing to higher consumption was the +2.9% growth – an increase of 224,400 – in the number of clients in this category.

COMPANHIA ENERGÉTICA DE MINAS GERAIS S.A. 10

Commercial and services: Energy distributed to these consumers was 12.2% of the total distributed by Cemig D in 3Q24, and by volume 0.7% more than in 3Q23. The increase is the result of a 7.7% reduction in the volume of energy billed to captive clients, and an 18.0% increase in the volume of energy transported for Free Clients. The higher consumption reflects: (i) expansion of the services sector, (ii) growth of retail sales, and (iii) temperatures above historical averages. It is worth noting that the increase in this user category happened in spite of the migration of consumers to Distributed Generation, which, along with migration to the Free Market, was reducing captive consumption.

Rural consumers used 7.6% of the total energy distributed by Cemig – and 6.4% more than in 3Q23 – this increase being partly due to lower than average rainfall in the quarter.

Public services consumed 6.6% of the energy distributed in 3Q24, a total 3.6% lower by volume than in 3Q23.

The Annual Tariff Adjustment

The tariffs of Cemig D are adjusted in May each year; and every five years are subjected to a Periodic Tariff Review, also in May. The aim of the Annual Tariff Adjustment is to pass on in full to the client any changes in costs defined as “non-manageable”, and provide inflation adjustment for the costs defined as “manageable”, as specified in the Tariff Review. Manageable costs are adjusted by the IPCA inflation index, less a factor known as the ‘X Factor’, to capture productivity, under a system using the price-cap regulatory model.

On May 14, 2024 Aneel ratified Cemig D’s Tariff Adjustment, to be effective from May 28, 2024 to May 27, 2025, with an average increase, for consumers, of 7.32%. The average effect was, for low-voltage consumers, an increase of 6.72%, and for residential consumers, an increase of 6.70%. The percentage component corresponding to manageable costs (referred to as ‘Portion B’) was 1.27%. The increase relating to non-manageable costs (‘Portion A’ – comprising purchase of energy, transmission, sector charges and non-recoverable revenues) was 0.81%. The increase in the financial components of the tariff contributed 5.23%. The effect in financial components in 2024 comes mainly from removal of the component included in the 2023 adjustment process relating to the repayment to consumers of PIS, Pasep and Cofins taxes (totaling R$ 1.27 billion).

Supply quality indicators – DEC and FEC

In 2023, Minas Gerais experienced an increase in extreme atmospheric events, causing a slight increase in electricity outages. In the context of this challenging scenario, Cemig has been implementing several initiatives to reduce the number and duration of outages. It is also making major investments in its distribution business to provide a quality service to clients, and intensifying measures to prevent outages in the rainy period of 2024–2025.

These actions are already producing positive results. The DEC indicator (average outage Duration per Consumer) returned to a level within the regulatory limit: in the 12-month window to end-September 2024 Cemig's DEC was 9.43 hours, within the regulatory limit of 9.64 hours.

Combating default

The Company has maintained a high level of collection actions, and this has helped keep the Receivables Recovery Index high: in September 2024 it was 98.67%, an increase of 0.46 percentage points from June 2024.

New payment channels, and online negotiation, have helped to increase the proportion of collection via digital channels (e.g. PIX instant payments, automatic debits, payments by card and app, etc.). This percentage reached 68.0% of the total collected in 3Q24, compared to 61.3% in 3Q23. The PIX system is a highlight: it was used for 27.2% of all collections – now a higher percentage than collection through the traditional channel of lottery shops. This system has saved R$ 26.4 million since it was implemented.

The change in the collection mix has reduced collection costs by 21% in the last year alone – since 3Q23.

Energy losses

Energy losses in the 12 months to the end of September 2024, at 10.76%, were higher than the regulatory target (10.57%). In relation to June 2024, losses decreased by 0.25 pp. The result above the regulatory level is partly due to: higher temperatures in September, and the corresponding supply not being invoiced by the end of that month.

Highlights of our combat of energy losses up to September 2024 include: approximately 301,000 inspections; replacement of more than 467,000 obsolete meters; replacement of 57,000 conventional meters by smart meters (bringing the total of smart meters installed since the project began in September 2021 to 400,000); and regularization of 9,500 clandestine connections made by families living in ‘invaded’ and low-income areas, through our Energia Legal program, which uses ‘bulletproofed’ networks (bringing the total of connections regularized since the start of the project in February 2023 to 18,000).

Cemig GT and Cemig Holding Company

Electricity market

The total volume of electricity sold by Cemig GT and by the holding company (‘Cemig H’), excluding sales on the wholesale power exchange (CCEE), was 1.5% lower than in 3Q23.

Cemig GT billed 5,125 GWh (including quota sales) in 3Q24, 11.6% less than in 3Q23. The lower figure is the result of transfer of sales contracts to Cemig H (the holding company) – which reported sales of 4,774 GWh in 3Q24, 12.3% more than in 3Q23.

The migration of purchase contracts from Cemig GT to the holding company was begun in 3Q21, and has been gradually increasing since then. It is now around 56%.

The volume of gas sold in 3Q24 was 3.7% lower than in 3Q23, while the volume distributed to industrial Free Clients was 102% higher, due to thermal dispatch. In the first nine months of the year, volume sold was 6.6% lower.

Gasmig’s 3Q24 Ebitda was 1.7% lower than in 3Q23, reflecting: (i) lower volume of gas sold, and (ii) the reduction of R$ 6.9 million received in the compensatory component included in the tariff (for differences between actual costs and cost included in the tariff award calculation).

The number of Gasmig’s clients increased by 9.7% from 3Q23, to a total of 101,273 consumers in 3Q24. This reflects expansion of both the commercial and the residential client bases (addition of 8,900 clients).

This expense refers to the charges paid by electricity distribution and generation agents for use of the facilities and components of the national grid and the electricity system. The amounts to be paid by the Company are set by an Aneel resolution.

The expense on acquisition of gas in 3Q24 was R$ 544.0 million, or 3.2% higher than in 3Q23. This variation reflects the higher price of gas purchased for resale in 3Q24, but with lower volume.

The main difference is in provisions for tax contingencies, in which there was a reversal of R$578,740 in 2Q24, compared to new net provisions of R$33,844 in 2Q23. The reversal was the result of the Company winning a court judgment which extinguished a demand for payment of social security contributions on profit shares paid to employees.

~~Ebitda~~§ a reversal, of ~~Cemig~~R$512, D774 in provisions for tax contingencies, compared to constitution of net new provisions totaling R$24,827 in 2Q23. This mainly reflects the judgment won in the courts by the Company, canceling a demand for payment of social security contributions on profit shares paid to employees and executives;

higher net new provisions for client default were made in 2Q24: R$72,447, compared to R$21,334 in 2Q23. This arises from the alteration, in August 2022, of the time limit for full recognition of unpaid receivables from 12 to 24 months, to give a more precise reflection of actual estimates of losses expected on overdue client bills. This change had effects over a period of 12 months, including the second quarter of 2023;
