Customer Relationships
Regulated utility service
Cemig serves about 9 million captive customers under Aneel-regulated rules, so service quality, billing, and outage response follow set standards. This relationship is long-term and continuous, with residential customers making up the core base and tariffs reviewed on a regulated cycle, not by short-term contract talks.
Digital self-service and billing support
Companhia Energética de Minas Gerais serves about 9 million customer units in Minas Gerais, so digital self-service matters at scale. Customers can check usage, pay bills, and file service requests through remote channels, which cuts friction in high-volume support and lowers call-center load.
Dedicated corporate account management

Channels
Physical grid connection
Companhia Energética de Minas Gerais delivers electricity through its physical distribution grid, the main channel for households and most businesses. In 2025, this backbone served millions of customers across Minas Gerais, making grid access the core of its utility model and revenue flow.
Transmission interconnection
Cemig’s transmission interconnection channel moves bulk power through its grid assets and interfaces, enabling wholesale delivery and system-wide balancing.

Customer Segments
Residential electricity users
Residential electricity users are Cemig’s largest captive base, with about 9 million connected customers across Minas Gerais, most served under regulated distribution tariffs. Households depend on standard billing, new connections, and outage response, so this segment stays central to steady, regulated revenue and cash flow.
Commercial customers
Commercial customers—retailers, offices, service firms, and small businesses—need stable power and often split demand between regulated and contract-based supply. For Companhia Energética de Minas Gerais, this segment supports distribution volume and retail revenue, with 2025 demand still anchored by Brazil’s low-voltage market, where small business load is a key base.
Industrial customers
Industrial customers are Cemig's high-value segment: they need 24/7 reliability and tailored price, volume, and supply terms for electricity, gas, and energy management. These large, multi-year contracts support trading and load planning, so even small changes in uptime or demand can move revenues and margins.
Public-sector and municipal clients
Public-sector and municipal clients are a natural fit for Companhia Energética de Minas Gerais, since government bodies, schools, hospitals, and concession holders buy power, grid access, and tech/operations support. Cemig’s scale in Minas Gerais matters here: it serves more than 9 million customers across 774 municipalities, so this segment sits close to its utility core.

Cost Structure
Network and plant operations
Companhia Energética de Minas Gerais runs 70 plants and a wide grid, so network and plant operations keep maintenance costs high. In 2025, spending on repairs, inspections, materials, and outage restoration was driven by reliability targets, because every service interruption adds direct cost and penalty risk.
Capital expenditures
Capital expenditures are a major cost for Companhia Energética de Minas Gerais because generation, transmission, and distribution networks need constant upgrades. The company has to keep building and renewing lines, substations, plants, and digital systems, so capex stays one of its largest utility spending buckets.
Personnel and outsourced services
Serving about 9.3 million customers in Minas Gerais, Companhia Energética de Minas Gerais needs engineers, technicians, field crews, and admin staff to keep power flowing. It also relies on third-party contractors for construction, maintenance, and tech support, so labor and outsourced services stay recurring and tied to network uptime.
Energy purchases and settlement costs
Cemig’s retail and trading units must buy energy and settle imbalances in the CCEE, so cost swings follow spot prices and demand. Gas logistics through Gasmig adds procurement, storage, and transport costs, which also move with market tightness and load.
- Power buys depend on market price
- Settlement risk rises with volume gaps
- Gas adds transport and logistics costs
Taxes, fees and technology spending
For Companhia Energética de Minas Gerais, taxes, concession fees, and regulated sector charges are a heavy cost line; in Minas Gerais, ICMS can reach 18%, and Brazil’s power bills also carry PIS/COFINS, so these items directly pressure margins. IT, cloud, and cybersecurity spending is also non-optional, because grid control, billing, and fraud defense need constant digital monitoring.
- Taxes and charges hit utility margins fast
- Concession fees are recurring cash costs
- Cybersecurity is a core operating expense
- Cloud and IT support daily reliability
Grid upkeep and power purchases drive Cemig’s cost pressure
Companhia Energética de Minas Gerais’ cost base is dominated by grid and plant upkeep, with 70 plants and 9.3 million customers driving constant repair, outage, and crew expenses in 2025. Capex stays heavy too, as lines, substations, plants, and digital controls need ongoing renewal; power purchases, CCEE settlements, and gas logistics add market-linked volatility.
| Cost item | Latest driver |
|---|---|
| Network upkeep | 70 plants; 9.3m customers |
| Power buys | Market-price exposure |
| Gas logistics | Procurement and transport |
Revenue Streams
Distribution tariffs
Distribution tariffs are Cemig's core, steady cash engine: regulated charges recover network O&M and grid investment costs from roughly 9 million customers across 774 municipalities in Minas Gerais. Because ANEEL sets the tariff base, this revenue is usually the most predictable part of the business model, unlike power sales that move with market prices.
Transmission tariffs
Companhia Energética de Minas Gerais’s 4,449-mile transmission network earns regulated access revenue through transmission tariffs tied to asset availability and system use, which gives the business steady, long-duration cash flow. In 2025/2026, that model remains a key earnings anchor because revenue is set by regulated allowed returns, not short-term power prices.
Generation electricity sales
Companhia Energética de Minas Gerais sells electricity from 70 plants through regulated contracts and the free market, with generation revenue driven by contracted volumes, spot prices, and dispatch. Its roughly 5,700 MW installed base gives it the scale to support this stream and capture price upside when output is sold into the market.
Gas, retail and trading income
Companhia Energética de Minas Gerais earns from natural gas acquisition, transport, and distribution, plus energy trading and retail contracts; in 2025, these three channels gave it more commercial flexibility by letting it move gas and power across spot and contract markets. The mix helps smooth revenue when demand or prices shift.
- Gas, trading, and retail diversify cash flow.
- Contract sales reduce volume risk.
- Trading adds margin from market spreads.
Technology, telecom and service fees
Cemig’s technology, telecom, and service fees turn operating know-how into cash, with cloud, IT, cybersecurity, account services, distributed generation, cogeneration, energy efficiency, and storage management all charging recurring fees. In 2025, these non-tariff services helped widen income beyond regulated power sales and improve margin mix.
- Monetizes utility capabilities
- Creates recurring fee income
- Supports DG, cogeneration, storage
- Broadens revenue beyond tariffs
CEMIG’s Regulated Grid Powers Stable, Diversified Revenue
Companhia Energética de Minas Gerais’s revenue streams are led by regulated distribution and transmission tariffs, backed by a 9 million-customer base across 774 municipalities and a 4,449-mile grid. Generation, gas, trading, and retail add upside and diversification, while technology and service fees widen recurring income.
| Stream | Core value |
|---|---|
| Distribution | ~9M customers |
| Transmission | 4,449 miles |
| Generation | ~5,700 MW |
