What Energisa does

Energisa S.A. is a publicly traded Brazilian energy holding company (B3: ENGI3) and the largest privately-held electricity distribution group in Brazil, operating 9 distribution concessions across 11 states that serve more than 20 million people across 939 municipalities. Founded in 1904 and headquartered in Cataguases, the group employs over 20,000 direct and indirect workers and invests approximately R$7 billion annually in distribution, gas, and distributed-generation infrastructure. The core business is regulated electricity distribution under tariffs set by ANEEL, with confirmed 30-year extensions covering 46% of group EBITDA as of February 2026.

Beyond regulated distribution, Energisa operates a diversified multi-energy ecosystem: ES Gás distributes natural gas (with biomethane added via the Lurean acquisition), (re)energisa runs 125 photovoltaic plants totaling 467 MWp for distributed solar and shared energy subscriptions, and Voltz provides fintech services (credit, insurance, receivables advancement). The technology stack includes the Energisa On mobile app, Agência Digital web portal, the Gisa AI-powered WhatsApp/web virtual assistant, URA phone systems, self-service totems, and a dedicated Portal Grandes Clientes for enterprise accounts, with innovation housed in FlexLab and Energisa Digital Labs.

Go-to-market combines digital self-service channels with physical branch offices and dedicated enterprise account managers; residential and commercial customers access the full product set across electricity, gas, and solar, while large commercial and industrial clients are served through specialized portals and free-energy-market advisory. Revenue is primarily recurring and tariff-based under regulated concession contracts, supplemented by subscription solar energy sharing, gas distribution, and consumer fintech. In Q1 2026, the group posted recurring adjusted EBITDA of R$1.98 billion (up 6.6% YoY) while net income fell 47% YoY to R$207 million due to elevated Brazilian interest rates driving R$1.59 billion of financial expenses.
