Acciona Energía plans to build a 196 MW/980 MWh battery energy storage system (BESS) at its El Romero solar farm in Chile’s Atacama region, with operations expected to begin by the end of 2027. The five-hour-duration project will nearly double the company’s energy storage capacity in Chile and complements the 200 MW/1 GWh BESS currently under construction at its Malgarida solar complex.
