Stars
Cemig SIM free-market retail expansion
Cemig SIM is a Star: Brazil’s free-market opening keeps widening its addressable base, while the legacy utility still grows more slowly. Cemig’s retail arm can scale faster than the core grid business, but it is still in share-building mode, so customer wins and sharp pricing stay key. In a market where migration keeps rising into 2025/2026, volume growth matters more than margin comfort.
Energy trading in the ACL market
Cemig’s energy trading in Brazil’s ACL market is a Star if it keeps scaling with liberalization and price swings. In 2025, the free market kept drawing larger industrial loads, while CCEE spot prices stayed volatile, so disciplined hedging and trading discipline matter. With strong scale, even small spread gains can lift returns fast.
Gasmig industrial gas expansion
Gasmig is a growth Star for Companhia Energética de Minas Gerais: it serves Minas Gerais industry, where fuel switching from oil and LPG can lift gas demand as factories run harder. The catch is capex-heavy growth, since new pipelines and service links must keep pace with new load. In BCG terms, this is a high-potential business that needs steady investment to hold share.
Wind and solar generation additions
Cemig’s Stars status is supported by renewable growth beyond hydro, with Brazil’s wind and solar fleet topping 70 GW of installed capacity by 2025. Solar and wind are still the fastest-expanding parts of the grid, so on-time project delivery can lift Cemig’s share and earnings mix.
- Beyond hydro, stronger growth runway
- 70+ GW wind and solar in Brazil
- Execution risk: schedule matters
Transmission reinforcement projects, 4,449 miles base
Cemig’s transmission base is 4,449 miles, or about 7,160 km, so the network already has scale. New lines and substation upgrades can keep this a Star while Minas Gerais load grows and renewable power needs more grid access, but returns stay capped by regulated tariffs and heavy capex.
- 4,449 miles of lines
- ~7,160 km network scale
- Growth driven by load and renewables
- Star status depends on capex discipline
Cemig’s Growth Stars Ride Brazil’s Market Opening
Cemig’s Stars are the faster-growing units: Cemig SIM, ACL trading, Gasmig, and renewables/transmission. Growth is tied to Brazil’s 2025/2026 market opening, 70+ GW of wind and solar, and Cemig’s 7,160 km transmission base. The key test is execution: win load, manage hedges, and keep capex disciplined.
| Star unit | 2025/2026 driver |
|---|---|
| Cemig SIM | Free-market migration |
| Transmission | 7,160 km grid scale |

Cash Cows
339,086 miles of distribution lines
Cemig’s 339,086 miles of distribution lines sit at the center of its regulated monopoly in Minas Gerais. The asset serves a huge, sticky customer base, so cash flows are recurring even when growth is modest. This is the clearest cash engine in the portfolio, with regulated tariffs and scale doing the heavy lifting.
4,449 miles of existing transmission lines
Companhia Energética de Minas Gerais’s 4,449 miles of transmission lines sit in a mature, regulated asset base. Once built, this network needs little marketing and usually delivers steady, tariff-backed cash flow, which is classic cash-cow territory. In a utility model, that kind of scale helps protect earnings even when growth is slow.
70 power plants, 5,700 MW installed capacity
Cemig’s 70 plants and 5,700 MW installed capacity show a large, mature generation base, with hydro assets that usually turn into steady cash once built. The fleet is legacy-heavy, so growth is slower, but the business can keep producing reliable operating cash from existing dams and plants. This fits Cash Cows: low expansion needs, stable output, and long-life infrastructure.
Captive electricity customer base in Minas Gerais
Companhia Energética de Minas Gerais’ regulated distribution arm serves millions of captive customers in Minas Gerais, so billing is repeatable and tied to a stable tariff base. Electricity demand is highly inelastic, which keeps cash flow resilient even when the economy weakens. That steady cash helps fund growth in generation, transmission, and renewables.
- Regulated concession supports recurring billings.
- Demand stays stable and inelastic.
- Cash flow funds higher-growth bets.
Regulated tariff revenue
Regulated tariff revenue is Cemig’s clearest Cash Cow: distribution rates are set by regulatory rules, so cash flow stays steady even when power use is flat. In 2025, Cemig served about 9.7 million customer units in Minas Gerais, which anchors this base revenue stream.
Because volume growth is limited, the upside comes mainly from lower losses, better outage control, and tighter opex, not from selling much more electricity. That is why regulated tariffs are a dependable funding source for dividends and capex.
- Stable, rule-based tariff cash flow
- Efficiency drives margin gains
- Large 2025 customer base supports scale
Cemig’s Regulated Grid Powers Steady Cash Flow
Cemig’s Cash Cows are its regulated distribution and transmission assets, which turn Minas Gerais’ captive demand into steady, tariff-backed cash flow. In 2025, the company served about 9.7 million customer units and operated 339,086 miles of distribution lines plus 4,449 miles of transmission lines.
| Cash Cow asset | 2025 scale | Why it matters |
|---|---|---|
| Distribution | 9.7 million customers | Recurring regulated revenue |
| Distribution lines | 339,086 miles | Stable monopoly network |
| Transmission lines | 4,449 miles | Tariff-backed cash flow |

Dogs
Telecommunications services
Telecommunications services are a non-core side line for Companhia Energética de Minas Gerais, far behind power and gas. The unit faces a crowded, capital-heavy market, so it is unlikely to build dominant scale or strong pricing power. In 2024, Companhia Energética de Minas Gerais posted R$24.9 billion in net revenue, and telecom remains a small add-on to that base.
Cogeneration projects
Cogeneration is a niche part of Companhia Energética de Minas Gerais’s mix, so it sits in the Dogs box of the BCG Matrix. Growth is far below solar, retail, and grid-linked businesses, which have clearer scale and demand. Small project size also limits operating leverage, so returns can stay muted.
Client account services
Client account services at Companhia Energética de Minas Gerais sit in the Dogs box: billing and back-office work keeps cash moving, but it is not a growth engine. It usually has thin margins and little product edge, so it looks more like overhead support than a strategic asset. In a utility serving about 9 million customers in Minas Gerais, scale helps, but it does not turn routine service work into a high-return business.
Supply and storage management
Supply and storage management fits the Dogs box because it is operationally necessary, but it is not a high-growth profit pool for Companhia Energética de Minas Gerais. In FY2025, this type of activity stayed largely transactional, with tight price pressure and little pricing power, so it mainly protects service levels rather than drives margin expansion.
Low growth, high execution need
Price-sensitive and transactional
Ties up working capital
Weak market power, limited upside
Specialized systems for public service concessions
Specialized systems for public service concessions sit in the Dogs bucket for Companhia Energética de Minas Gerais: they are niche B2G projects, not a repeat volume engine. Demand is tied to isolated bids and concession cycles, so revenue can swing with each tender. Low scale also limits pricing power and makes it hard to build a durable share edge.
- Small, project-based B2G demand
- Weak repeat sales visibility
- Hard to gain lasting scale
CMIG’s Dog Units Remain Small, Costly, and Low-Return
Dogs at Companhia Energética de Minas Gerais are small, low-growth lines that need work but do not move value. They face weak pricing power, thin margins, and limited scale, so cash use stays high for the return they bring. In FY2025, these units stayed minor next to Companhia Energética de Minas Gerais's 9 million-customer core.
| Dog unit | Why it fits |
|---|---|
| Telecom | Small, crowded market |
| Cogeneration | Niche, low scale |
| Client services | Support role, thin margin |
Question Marks
Cloud solutions
Cloud solutions sit in a fast-growing Brazilian enterprise market, but Companhia Energética de Minas Gerais is not a core national cloud leader, so this is a clear question mark. In 2025, cloud demand in Brazil kept rising on digitalization, AI, and data-storage needs, while larger providers still dominated scale and mindshare. For Companhia Energética de Minas Gerais, the key test is whether cloud can win share fast enough to justify more capital.
Cybersecurity services
Cybersecurity services fit as a Question Mark for Companhia Energética de Minas Gerais because demand is rising across utilities, but the business still needs scale. The global cyber market is already above US$200 billion in 2025, yet Cemig’s current share is likely small versus its core power and grid assets. Growth is real, but it needs faster client wins and bigger contracts to turn into a Star.
IT infrastructure and management
IT infrastructure and management looks like a Question Mark for Companhia Energética de Minas Gerais: utility digital spend stays strong, but external scale is still thin. Cemig can sell into its own grid and customer base, yet that captive demand does not prove broad market pull. With Brazil’s power sector pushing smart metering, automation, and cyber upgrades, the unit needs faster revenue growth and wider client wins to move up the matrix.
Distributed generation initiatives
Distributed solar in Brazil keeps scaling fast, with distributed generation topping 30 GW of installed capacity in 2025. Cemig’s core market is large, but its share is still far from dominant, so this sits in the Question Marks bucket.
To protect share, Cemig needs heavy capex, faster grid hookups, and better customer capture before rivals lock in the market.
- Brazil DG: 30 GW+ in 2025
- Large market, weak Cemig share
- Needs aggressive investment now
Energy efficiency programs
Companhia Energética de Minas Gerais’s energy efficiency programs fit a Question Mark in the BCG Matrix: policy support can keep demand alive, but margins are usually thinner than core regulated power distribution. In Brazil, decarbonization and lower-bill savings can lift volumes, yet the segment only turns into a Star if it scales faster than the broader market and wins repeat contracts.
- Policy-backed growth, but weaker returns.
- Best case: scale faster than market demand.
- Still below core regulated utility profitability.
Cemig’s High-Growth Bets Need Speed, Scale, and Capex
Companhia Energética de Minas Gerais’s Question Marks need fast scale and heavy capex: cloud, cyber, and IT services still have weak market share, even as Brazil’s digital spend rises in 2025. Distributed solar passed 30 GW in 2025, but Cemig is not a dominant player yet. Energy efficiency also has policy support, but margins stay thinner than core utility work.
| Area | 2025 signal | BCG fit |
|---|---|---|
| Cloud | Fast growth | Question Mark |
| Cybersecurity | US$200B+ market | Question Mark |
