Brazil moves ahead with battery storage rules and renewable energy investments

The Brazilian electricity regulator Aneel approved new regulations for energy‑storage systems, setting out the requirements for outorgas and removing the double‑charging tariff for autonomous batteries that are dispatched by the National System Operator (ONS). The rules accompany the upcoming guidelines for Brazil’s first battery auction, scheduled for December 2026.

Minister of Mines and Energy Alexandre Silveira highlighted the country’s clean‑energy matrix and the need for a regulatory framework to support a surge in data‑center and AI projects, noting 38 GW of connection requests and 7.1 GW of investments worth R$ 159 billion.

Mineral producer Samarco signed a long‑term partnership with Casa dos Ventos to supply 45 MW of wind power from the Serra do Tigre complex, part of its plan to cut carbon emissions 30 % by 2032 and achieve carbon neutrality by 2050.

Moura showcased a diversified line of stationary batteries at Exposec 2026, stressing that reliable backup power is now critical for connected security systems and announcing a small‑scale storage unit aimed at residences and small businesses.

The Minas Gerais state government introduced tax incentives, including ICMS deferments and exemptions, for the use of clean energy in industry, supporting biometane, green hydrogen, biodiesel and solar projects, while the state’s electricity mix reached 99.4 % renewable sources.

The Ministry of Mines and Energy (MME) also promoted Brazil’s offshore‑wind potential – about 1,200 GW technically feasible – during a Brazil‑Denmark delegation, stressing transparent planning and coordination with international partners.
