**Rio de Janeiro, March 18, 2026** – Petróleo Brasileiro S.A. – Petrobras announces that it has contracted eight power plants from its thermoelectric energy portfolio in the 2026 Capacity Reserve Auction (LRCAP 2026), held today by Brazil's National Electric Energy Agency (ANEEL) and the Electric Energy Trading Chamber (CCEE), with technical support from the Energy Research Company (EPE).

The auction aimed to contract firm capacity for the National Interconnected System (SIN), involving natural gas-fired and coal-fired thermal power plants, as well as expansions of hydroelectric plants, according to guidelines established by the Ministry of Mines and Energy (MME).
