Southern Power has completed the energy storage additions to two solar projects in California.
“These co-located solar and storage projects are a first of their kind for Southern Power,” said Southern Power President Bill Grantham. “We expect these new battery-based energy storage projects to enhance California’s grid reliability. The combination of our solar technology and these new energy storage resources will further position Southern Power to meet our customers’ needs as the energy industry continues to evolve.”
The 205-MW Garland Solar Facility in Kern County now has 88 MW (352 MWh) of energy storage, and the 204-MW Tranquility Solar Facility in Fresno County has added 72 MW (288 MWh) of storage.
The resource adequacy capacity benefits of both battery facilities are being sold under a 20-year PPA to Southern California Edison.
The energy storage projects are owned in partnership with KKR and AIP Management (on behalf of Danish pension funds PKA and PenSam), each of which have existing ownership interests in the Garland and Tranquility solar facilities.
Rosendin Electric served as the constructor of the sites, and Mitsubishi Power Americas served as the equipment supplier utilizing Powin Energy Corporation batteries. Mitsubishi Power Americas will also service the projects under a 20-year long-term service agreement.
