Battery energy storage systems (BESS) cost base has increased 25% in the past year, the head of storage for global energy technology group Wärtsilä told Energy-Storage.news.
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.
South African energy company Kibo Energy will procure two vanadium redox flow battery system pilot projects from CellCube, the first step in a larger rollout.
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).
