Energy technology company Wärtsilä is supplying 500MW/2,000MWh of battery energy storage systems (BESS) to PV projects operated by Clearway Energy Group in Hawaii and California, US.
Battery storage capacity in the US more than tripled to 4,631GW in 2021 and increasingly broadened out of ancillary services, according to the Energy Information Administration (EIA).
Volkswagen has started construction of its 40GWh battery cell gigafactory in Salzgitter, Germany, and the company plans to dedicate capacity to grid-scale energy storage in future.
