Support Activities
Firm Infrastructure
Companhia Energetica de Minas Gerais uses a centralized firm infrastructure to manage generation, transmission, and distribution under ANEEL rules. In 2025, it is backing this with a $7.5 billion capex plan to modernize grid assets and lift resilience. Debt control and environmental licensing stay key, because they affect funding capacity and project timing across Minas Gerais and nearby markets.
Human Resource Management
Companhia Energetica de Minas Gerais employs about 5,000 professionals, and HR centers on technical training for field engineering and high-voltage maintenance teams to keep service reliable. That matters because the company serves millions of homes and industrial customers on a 24/7 grid, where small skill gaps can trigger outages.
HR also manages union relations to support labor stability, while recent training has shifted toward digital skills for a more automated grid.
Technology Development
By 2025, Companhia Energetica de Minas Gerais had pushed digitalization across its distribution network and expanded advanced metering infrastructure over a 211,000-mile grid. Its R&D work supports predictive maintenance for 50+ hydroelectric plants and better grid control for solar and wind. These upgrades cut outages, lower operating cost, and improve asset use.
Procurement
In 2025, CEMIG's procurement sat at the center of support activities, buying turbines, high-capacity transformers, and grid-maintenance inputs for generation and transmission. Centralized sourcing lets Company Name use scale to get lower prices from local and global vendors, including for the Minas Trifásico buildout.
It also manages power purchase agreements to balance owned output with regulated demand, which helps control supply risk and cost.

Primary Activities
Inbound Logistics
CEMIG's inbound logistics centers on reservoir and river-flow control across Minas Gerais basins, because most of its output comes from hydro plants; Brazil's hydro fleet still supplies about 60% of power, so forecast accuracy matters.
It also buys and moves fuel for thermal units and imports power from third parties and Itaipu, whose plant has 14,000 MW installed capacity.
That buffer helps CEMIG protect supply in drought years and keep generation steady.
Operations
Companhia Energetica de Minas Gerais runs operations across more than 50 power plants with over 6,000 MW of installed capacity, so plant uptime is the main value driver. Maintenance teams combine field inspections with control-center monitoring to keep the grid running at about 99% availability. In 2025, this focus on asset reliability and loss control supports steadier output and lower outage risk.
Outbound Logistics
In 2025, Companhia Energética de Minas Gerais moves power through a distribution grid serving about 9.3 million connection points, so outbound logistics are really about keeping electricity stable from plant to customer. The company uses voltage control and loss reduction across long lines to keep power usable for homes and factories. That matters most in southeastern Brazil's industrial hubs, where even short outages can hit output and cash flow fast.
Marketing and Sales
Companhia Energetica de Minas Gerais uses segmented marketing to sell power to regulated users and bids hard in the Free Market (ACL) for large corporate buyers. Its sales team builds tailored contracts for industrial clients that want high supply reliability and cleaner power, backed by renewable energy certifications. A strong Minas Gerais brand helps Companhia Energetica de Minas Gerais win premium contracts in tight bidding cycles.
Service
CEMIG's service layer uses digital apps, physical offices, and emergency crews to handle billing, faults, and localized grid outages fast. Its advanced billing and energy-use advice help customers cut waste and make the firm less exposed to churn in competitive retail supply.
Service quality also matters for regulation: Brazilian energy regulator ANEEL tracks customer satisfaction and continuity metrics, and those scores can affect tariff outcomes for Companhia Energetica de Minas Gerais.
Cemig: 6,000+ MW, 9.3M Connections, 99% Availability
Companhia Energetica de Minas Gerais' primary activities are hydro-heavy generation, thermal backup, and power purchases, with more than 50 plants and over 6,000 MW installed in 2025. That mix keeps supply flexible when reservoirs weaken.
Its operations focus on plant uptime and grid control, with about 99% availability across the fleet. On the outbound side, a 9.3 million-point distribution network makes loss control and voltage stability critical.
Sales and service support regulated and free-market customers with contracts, billing, outage response, and customer care.
