California’s recent droughts and ongoing need to economise water use have inspired more commercial energy storage at a local water board, with ENGIE Storage delivering a project for the San Diego Water Authority.

San Diego Gas & Electric (SDG&E), one of California’s three main investor-owned utilities (IOUs), said this week that it will add resilience and backup capabilities to public sector buildings through the procurement of “up to 166MW” of energy storage.

Steps taken in California to enable energy storage systems to provide multiple services and to ‘stack revenues’ are “an essential starting point” for the industry, the head of California’s Energy Storage Alliance (CESA) has said.

Infrastructure EPC company Black & Veatch will evaluate proposals received for a 500MW pumped hydro energy storage facility in San Diego, California.

The US’ two leading states in solar and energy storage, New York and California, have taken steps towards valuing the locational and time-of-use value of distributed energy resources and other states should follow, the Solar Energy Industries Association (SEIA) has said.

Leaders in the fledgling commercial and industrial (C&I) sector in the US have made energy storage ‘as-a-service’ the core of their proposition, a market analyst has said.

“A comprehensive agenda to combat climate change” unveiled on Tuesday by New York governor Andrew Cuomo, includes the setting of a state-wide energy storage deployment target of 1,500MW by 2025.
