Battery energy storage is load shifting up to 6GWh a day on the California ISO (CAISO) grid, storage sector manager Gabe Murtaugh told Energy-storage.news, as the operator considers a market design change linked to batteries’ state of charge (SoC).

Deadline for commissioning large-scale battery storage for California utility Southern California Edison might be missed, Ameresco has said.

Californian investor-owned utility San Diego Gas & Electric has released its decarbonisation roadmap study.

Southern Power has turned two four-hour battery energy storage systems (BESS) totalling 640MWh at two of its solar facilities in California online.

Investor-owned utility SDG&E is turning its first lithium iron phosphate-based battery energy storage system (BESS) online today, while Stanford university says it has hit 100% renewable electricity with the offtake from Goldman Sachs’ recently-commissioned Slate solar-plus-storage project.

It’s been a positive week for thermal energy storage technology, with utility Edison International validating a cold storage solution, a collaboration between two groups to achieve 100% round trip efficiency, and an acquisition involving several intellectual property rights patents.

Battery storage will be a valuable asset for enhancing and upgrading the electric transmission and distribution (T&D) system of California.

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

There is still plenty of educating decision-makers on storage’s place on the grid to do for US states to follow in the footsteps California and Texas.

Ameresco has secured a US$262 million increase to its credit facility, supporting the company’s 2.1GWh battery project in California.
