US utility Pacific Gas & Electric Company (PG&E;) has unveiled proposals for an additional 387MW of combined battery storage capacity to boost the use of renewables and increase the reliability of the grid in California.

PG&E; is asking the California Public Utilities Commission (CPUC) to approve the plan, which would see the construction of six additional lithium-ion battery energy storage projects.

Fong Wan, PG&E;’s senior VP for energy policy and procurement, said: "The next few years will be pivotal for the deployment and integration of utility-scale battery energy storage onto the grid.”

'Clean energy goals'

"PG&E; has awarded contracts for battery energy storage projects totalling more than 1,000MW of capacity to be deployed through 2023, all of which contribute to meeting California's ambitious clean energy goals while ensuring grid efficiency and reliability, reducing the need to build additional fossil fuel generation plants, and keeping customer costs affordable.”

California has continued to be a magnet for battery storage and renewables development over the past year – with the need to shore-up reliable power supplies heightened during an historic heatwave across the state earlier this year.

Last August, LS Power unveiled the world’s "largest battery energy storage project” – a 250MW capacity facility in California’s San Diego County.

In October, plans for a major solar project in California were expanded to include a 200MWh battery energy storage system, in an agreement between EDF Renewables North America and CleanPowerSF.
