Storage: MME sets rules for battery-based auctions scheduled for December

On June 3, 2026, Brazil’s Ministry of Mines and Energy (“MME”) published Ordinance No. 136/2026, establishing the framework and guidelines for conducting two Power Reserve Capacity Auctions (“LRCAPs”) involving new battery-based energy storage systems (BESS, or “SAEs” in Portuguese), namely:

• 2026 LRCAP – National Storage (through new SAEs with domestic content); and
• 2026 LRCAP – Storage (through new battery-based energy storage systems).

The auctions aim to ensure continuity of the electricity supply to meet the power requirements of the National Interconnected System (“SIN”), through the contracting of battery-based SAEs.
