Petrobras Signals Entry Into Brazil’s 2026 Battery Storage Auction

Overview

• Petrobras said it plans to take part in the 2026 Reserve of Capacity auctions, including the battery-focused tranche expected in April.
• The company also intends to compete in the March power auction, citing 2.9 GW of uncontracted thermal capacity.
• Under the government’s design, battery projects will receive 10-year reserve-capacity contracts with operation starting in 2028.
• The MME requires contracted systems to fully recharge within six hours and to guarantee a minimum daily availability of power.
• Investment scale and whether Petrobras bids alone or with partners will hinge on the edital, with batteries already included in its 2030 plan and a pilot tied to a Juiz de Fora thermal plant.
