California Community Power Members Contract for 69 MW of Long-Duration Energy Storage

LCG, January 26, 2022--The California Community Power (CC Power) board members of the Joint Powers Agency last week voted to enter into an energy storage service agreement with REV Renewables for a 69 MW/552 MWh of long-duration (8-hour) battery energy storage system (BESS). The REV Renewables Tumbleweed Project will be a California Independent System Operator (CAISO) grid-connected, lithium-ion battery storage resource. The facility will be located near Rosamond, in Kern County, California and is scheduled to be online in 2026.

The seven CC Power participating members for this project are CleanPowerSF, Peninsula Clean Energy, Redwood Coast Energy Authority, San Jose Clean Energy, Silicon Valley Clean Energy, Sonoma Clean Power Authority and Valley Clean Energy. REV Renewables is an LS Power company that was launched in August of 2021 to develop, acquire and operate energy storage and renewable projects.

The CC Power Board Chair and Silicon Valley Clean Energy CEO stated, “Long-duration energy storage is a vital resource, needed to amplify the value of renewable power, and accelerate California’s shift to a clean, reliable and affordable grid. This first project is an exciting milestone that shows how CCAs work together to advance our shared goals in the transition to a carbon-free grid.”

The California Public Utilities Commission (CPUC) Mid-Term Reliability Procurement order (Decision 21-06-035) requires all CPUC-jurisdictional load serving entities, including CC Power Members, to procure from energy storage facilities capable of discharging for a minimum of 8 hours. The Tumbleweed Project is expected to satisfy approximately 55 percent of the long-duration storage compliance requirements of the participating members.

This joint procurement effort for long-duration energy storage began before the CPUC issued the new procurement order when a subset of the CC Power members issued a Request for Offers (RFO) in October 2020 seeking to procure cost-effective, long-duration storage resources.
