Energy storage system of 30 MW/120 MWh comes online in California

The 30-MW/120-MWh Top Gun energy storage project in San Diego, California has recently started commercial operation, UK-based renewable energy company RES said on Tuesday.

RES delivered the project to San Diego Gas & Electric Company (SDG&E), a subsidiary of Sempra (NYSE:SRE) serving San Diego and southern Orange counties. RES will provide operations and maintenance services for the system over the next 20 years.

The facility, whose construction began in early 2020, consists of more than 15,000 lithium-ion batteries installed in custom enclosures.

The project is situated next to Marine Corps Air Station Miramar and is named after the Top Gun naval aviation training programme formerly located there.

"As climate change fuels more extreme weather events, such as record heat waves, energy storage serves as a critical resource to prevent or limit power outages," said SDG&E's director of advanced clean technology Fernando Valero.
