Companhia Energetica de Minas Gerais Business Model Canvas

Operate a diversified fleet of hydro, thermal, wind and solar plants to meet regulated load and market commitments, optimizing dispatch with real-time hydrology, fuel costs and spot prices. Maintain high availability and efficiency while ensuring compliance with ANEEL and environmental standards through preventive maintenance and emissions controls. Coordinate dispatch closely with ONS and in-house trading desks to balance supply, manage bilateral contracts and optimize revenue.

Maintain lines, substations and distribution networks across CEMIG’s ~9 million customers to ensure reliability and safety, executing preventive and corrective maintenance via digital work-management platforms. Grid modernization targets loss reduction (current distribution losses ~13%) and SAIDI/SAIFI improvements—aiming double-digit percentage cuts through automation and sectionalizing. Use smart sensors and SCADA for rapid fault detection and restoration to minimize outage duration.

Hydro, thermal, wind and solar assets deliver both baseload and flexible capacity across CEMIG’s diversified fleet, supporting about 8.8 GW of installed capacity in 2024. Geographic and technological diversity reduces exposure to hydrology and spot-price shocks, while long asset lives and refurbishment potential sustain predictable cash flows. This capacity base enables significant contractable energy for PPAs and regulated markets.

Companhia Energética de Minas Gerais sustains value delivery through extensive transmission and distribution networks—serving about 8.7 million customers across Minas Gerais and operating over 100,000 km of lines, substations and feeders that reach beyond state borders. Grid scale enables economies and redundancy, lowering unit costs and improving reliability. Advanced protection systems, capacitor banks and automation preserve voltage quality and reduce losses, making physical infrastructure central to service delivery.

High network uptime (99.9% in 2024) and average outage restoration under 2 hours minimize customer disruption and support continuous economic activity. Robust O&M programs and N-1 redundancy improved service quality metrics, reducing interruptions and raising customer satisfaction. Clear safety protocols cut workplace incidents by 12% year-on-year, protecting people and assets and reinforcing trust.

Combining hydro, wind and solar lowers carbon intensity and price volatility for CEMIG; Brazil’s power matrix remained ~80% renewable in 2024 (EPE), underpinning cleaner supply. Hybrid portfolios improve resilience to hydrology and fuel shocks, reducing spot exposure for customers. Customers access cleaner energy via contracts and green programs, supporting ESG targets and regulatory alignment.

24/7 multichannel incident reporting (call center, app, SMS, web) supports CEMIG's 8.7 million customers in 2024, enabling real-time updates and automated outage maps. Proactive notifications during planned maintenance and storms reach registered users, reducing surprise interruptions. Clear ETAs and post-event feedback loops drive continual improvement in restoration times. Reliability-focused service contributes to measurable confidence and lower complaint rates.

Dedicated CEMIG teams manage industrial and large commercial clients, covering operational, commercial and technical needs for over 8 million customers (2024). Customized SLAs, tailored tariffs and efficiency roadmaps improve uptime and cost-per-MWh for high-demand accounts. Joint planning for network expansions and on-site generation accelerates projects and reduces interconnection lead times. Deep key-account relationships cut churn and lift cross-sell of services and energy solutions.

A primary physical channel delivering electricity to end-users, CEMIG Distribuição serves approximately 8.9 million customers across 774 municipalities in Minas Gerais. The network ensures last-mile reach across urban and rural areas, underpinning access for households and businesses. Performance of this channel is directly linked to service quality KPIs such as continuity and response times. It is essential for value realization and revenue collection across the concession area.

Phone, chat and over-the-counter agencies handle requests and bill payments for Companhia Energetica de Minas Gerais, serving about 8.8 million distribution customers in 2024. A centralized ticketing system tracks interactions and enforces SLAs across channels. Multilingual and accessible services expand reach across Minas Gerais. Human agents complement self-service portals and chatbots for complex cases.

Residential households (about 6.8 million CEMIG distribution customers) require safe, affordable, reliable power and increasingly demand digital billing, flexible payments and real-time outage transparency. Rooftop solar and net metering adoption is growing, with thousands of residential prosumers in the CEMIG concession by 2024, pressuring grid services and billing systems. Service quality strongly drives satisfaction, complaints and payment behavior.

Retailers, service firms and small industries with moderate loads prioritize predictable bills and basic efficiency measures; many are strong candidates for tariff optimization to lower costs. They value quick connections and responsive support to minimize downtime and cashflow disruption. In Brazil SMEs represent about 99% of companies, underscoring scale opportunity for CEMIG in 2024.

CEMIG’s capital expenditures concentrate on plants, transmission lines and substations plus digitalization, with a reported 2024 investment plan of approximately R$4.1 billion to support expansion and modernization. Repowering and grid automation require sustained capex to reduce losses and improve reliability, while environmental and compliance spending secures operating licenses and mitigates regulatory risk. The timing and cadence of these investments directly shape long-term returns and tariff trajectory.

Routine and major maintenance on Cemig’s generation and network assets covers scheduled outages, spare parts inventories, inspections and contractor services to sustain fleet availability. Vegetation management and targeted loss-reduction programs address Brazil’s distribution losses, which ANEEL reported at 12.8% in 2023, improving uptime and safety. O&M investments directly support reliability metrics such as SAIDI and SAIFI, reducing interruption frequency and duration. Spare parts and inspection cycles are budgeted to minimize forced outages.

Revenue derives from ANEEL-set tariffs charged to about 9 million captive customers (2024), with periodic tariff reviews and annual adjustment mechanisms. Tariff formulas incorporate allowed returns on regulated asset base and pass-through costs such as energy purchase and transmission. Realized volumes and distribution losses materially affect billed revenue and reconciliations. This regulated income provides CEMIG a stable cash-flow backbone.

Transmission availability revenues for Companhia Energética de Minas Gerais derive from RAP and related payments that remunerate grid availability under ANEEL concession contracts, with amounts indexed to inflation (IPCA) to provide cashflow predictability. Contractual schemes include performance and expansion incentives and penalties that align earnings with reliability and network build-out. These revenues carry much lower demand risk compared with energy sales, since they are availability-based rather than volumetric.
