Brazil's electricity regulator, ANEEL, has approved reserve capacity auctions set for March 18 and 20, 2026, for thermal and hydro plants, with more than 125 GW registered. The auctions include a second LRCAP for hydroelectric and thermoelectric plants utilizing natural gas and coal, and a third LRCAP for plants powered by diesel, fuel oil, and biodiesel.

ANEEL has also recommended to the Ministry of Mines and Energy the consideration of regionalized auctions. Guidelines for a battery storage auction remain pending, while over 20 GW of battery projects are currently in development.
