Support Activities
Firm Infrastructure
In 2025, CEMIG's firm infrastructure centered on its corporate hub, which coordinated regulated power, gas distribution, and energy sales under Brazilian utility rules. It had to align planning, risk control, and capital allocation across generation, transmission, distribution, and trading in Minas Gerais and other regions. With about 9 million customers, tight governance and capital discipline were critical.
Human Resource Management
Companhia Energetica de Minas Gerais depends on engineers, line crews, plant operators, dispatchers, and customer service teams to keep generation, transmission, and distribution running. In 2025, this human resource base matters most in safety training, outage response, and asset reliability, because even short crew delays can extend service interruptions. Strong training and shift discipline help protect a large technical workforce and keep operating risk and downtime lower.
Technology Development
Cemig used grid automation, SCADA control systems, smart metering, and data tools to tighten dispatch and cut technical losses across its 2025 network that serves about 9 million customers in 774 municipalities. Its digital layer also helps balance hydro, thermal, wind, and solar assets, so power can move from generation to distribution and trading with fewer delays. Better data improved outage handling and service quality, while supporting lower operating cost per unit delivered.
Procurement
Procurement is critical at Companhia Energetica de Minas Gerais because it buys transformers, spare parts, construction services, fuel for thermal plants, and other inputs that keep a network serving about 9 million customers running. In a utility with heavy capex, slow sourcing can delay grid work, raise outage risk, and push back tariff and project timelines.
Strong supplier control also matters for price and quality, since equipment lead times and fuel costs can swing maintenance and plant availability.
CEMIG's 2025 support engine: governance, digital control, and disciplined procurement
In 2025, Companhia Energetica de Minas Gerais support activities were built around tight governance, a technical workforce, digital control, and disciplined procurement. With about 9 million customers in 774 municipalities, SCADA, smart metering, and data tools helped reduce outages, technical losses, and dispatch delays. Procurement of transformers, spare parts, and fuel was critical to limit downtime and protect heavy capex plans.

Primary Activities
Inbound Logistics
In 2025, Companhia Energetica de Minas Gerais managed a supply base built around thermal fuels, grid-maintenance equipment, and materials for new lines and substations. Its scale matters: the company served about 9.3 million customer units, so even small delays in spares or construction inputs can hit service quality.
For hydro assets, water inflow and reservoir levels also shaped dispatch flexibility and fuel needs. So inbound logistics was not just procurement; it was a control point for plant uptime, grid expansion, and operating cost.
Operations
CEMIG's Operations segment turns hydro, thermal, wind, and solar output into cash flow by running generation, transmission, and distribution assets across Minas Gerais and beyond. It also adds gas distribution and energy sales, widening the customer base to more than 9 million electricity users and reducing dependence on one revenue line.
This integrated setup helps CEMIG capture value across the power chain, from plant dispatch to grid delivery and retail commercialization.
Outbound Logistics
Companhia Energética de Minas Gerais moves electricity from its plants through transmission and distribution lines to more than 9 million customer units in Minas Gerais, covering homes, shops, and factories. Metering, dispatch, and settlement systems track every MWh so billed volumes match delivered power and grid losses stay controlled. In 2025, this last-mile delivery step remained central to revenue capture because regulated network use and energy sales depend on accurate measurement and timely settlement.
Marketing and Sales
In 2025, Companhia Energética de Minas Gerais focused marketing and sales on regulated power customers and on commercial and industrial clients that need tailored contracts. The team worked on tariff management, account retention, and pricing terms matched to each load profile, helping protect recurring revenue while supporting cross-selling of energy solutions.
Service
Companhia Energetica de Minas Gerais service work covers outage response, billing support, customer care, and field maintenance, which matters most after the sale. In 2025, this layer protects service quality in a utility that must keep power flowing across a large state network. Fast fault repair and clear billing help cut complaints and keep customers from churning to legal or regulator channels.
Cemig's 2025 Power Chain Reached 9.3 Million Customer Units
In 2025, Companhia Energetica de Minas Gerais generated, moved, sold, and serviced power for about 9.3 million customer units, so its primary activities were tightly linked. Operations and outbound delivery kept hydro, thermal, wind, and solar output flowing through transmission and distribution lines. Sales and service then protected recurring revenue through tariffs, billing, outage response, and field support.
