What Cemig Sim does
Cemig SIM is a Brazilian distributed solar energy company and a wholly-owned subsidiary of Grupo Cemig, the diversified Minas Gerais energy conglomerate with over 70 years of operating history. Founded in 2019 and headquartered in Belo Horizonte, the company operates 21 solar plants across 14 municipalities in Minas Gerais, totaling 300 MWp of installed capacity, and serves more than 6,000 residential, commercial, industrial, rural, and government customers with remote solar energy subscriptions. Its core product, Energia Solar por Assinatura, allows customers to receive solar credits on their electricity bills without installing on-site equipment, by injecting energy from Cemig SIM's plants into the distribution grid via Brazil's distributed generation compensation framework.
The company's technology stack centers on distributed photovoltaic generation paired with the EnergySIM AI-driven monitoring platform, which collects consumption data to inform efficiency decisions. Product breadth has expanded beyond subscriptions to include shared solar farms (Fazenda Solar), custom solar plant construction (Sua Usina Solar), electric mobility services (SIM Mob), energy efficiency consulting, and renewable energy certification (Selo de Energia Limpa, Cemig SIM REC). Commercial go-to-market is hybrid: a digital-first direct-to-consumer motion (website, WhatsApp chatbot, mobile app with self-serve savings calculator) for residential and SMB customers, paired with inside sales and B2B commercial teams for enterprise contracts.
Cemig SIM generates revenue primarily through recurring monthly subscriptions for solar energy credits at discounted rates versus utility tariffs (12-26% for residential, up to 30% for B2B, up to 95% for custom enterprise installations), supplemented by professional services revenue from custom solar plant development and consulting. The company has accumulated over R$38 million in customer savings since 2019, generated 217+ million kWh, and avoided 42+ tonnes of CO2 emissions, with a stated R$3.5 billion investment plan through 2029 to scale solar generation capacity.
