US energy storage developer Gridstor has announced the start of construction of its first project, a 60MW/160MWh BESS in California.

New developer GridStor has acquired a portfolio of in-development battery storage projects in LA, California, from Upstream Energy, totalling 500MW/2,000MWh.

Goldman Sachs and Cleanhill Partners have swooped to acquire a majority stake in EPC Power, a US manufacturer of power conversion systems.

Compressed air long-duration energy storage solution provider Hydrostor has received an investment commitment of US$25 million from Canada Pension Plan Investment Board.

Goldman Sachs Renewable Power has cut the ribbon on a large-scale solar-plus-storage project in Kings County, California.

Hydrostor CEO Curtis VanWalleghem talks advanced compressed air energy storage and how Goldman Sachs Asset Management came to invest US$250m in his company.

Financing has been secured for two projects that will add nearly a gigawatt-hour of battery storage at California solar power facilities this year, by renewable energy company Terra-Gen and private asset management firm Capital Dynamics.

Investment giant Goldman Sachs will invest US$150 billion in renewables by 2025, including energy storage as a key part of this commitment, it has said.
