Brazil Sets Record with 297 Gigawatts in Its First Battery Auction

Brazil's Energy Research Company (EPE) registered 6,091 projects totaling 296.8 gigawatts (GW) for the country's first battery storage auction, according to a report published on August 3, 2026. The submission, a record for participation in the Brazilian electricity sector, contrasts with the 2 to 5 GW the government expects to contract.

The process is governed by the Leilão de Reserva de Capacidade (LRCAP) in its storage capacity modality, established by normative ordinance 136 from the Ministry of Mines and Energy, issued in June 2026. The auctions will be held on December 2 and 4: the first will be reserved for projects with national content, and the second will be open to equipment of any origin. Winners will sign 15-year contracts to deliver capacity availability to the National Interconnected System (SIN), with operations expected to begin in August 2028. The scale of submissions positions Brazil as the market with the largest volume of battery storage projects under review in Latin America, a signal of private capital's interest in the segment.

According to pv magazine Latam, submissions exceed 260 GW in the national content auction and 280 GW in the open one; the Northeast accounts for 71.1% of registered capacity and the Southeast for 18.8%, in line with the location bonus established for priority zones. According to Reuters, 4,939 of the 6,091 projects registered for both modalities, and expected demand of 2 to 5 GW anticipates tight competition. Systems must guarantee at least four hours of discharge and a maximum of six hours of recharge. EPE attributes the volume to the modular nature of the projects and to the fact that registration requires neither an environmental permit nor prior certification; technical qualification, scheduled for November 17, will filter the final list.

The gap between the 296.8 GW registered and expected demand of 2 to 5 GW will be resolved at two milestones: the list of qualified projects on November 17, and the auctions on December 2 and 4. The outcome will indicate whether the record submission translates into contracted capacity and an investment signal for the region.
