Southern Power completes work on two energy storage projects in California
Southern Power announced that new battery energy storage projects at its Tranquillity and Garland solar facilities in California are now fully operational.
The capacity from both battery facilities has been sold to Southern California Edison under a 20-year power purchase agreement. The energy storage additions will provide Southern California Edison and the California ISO with additional flexible resource capacity for the grid.
At peak capacity, the Garland Solar Facility Battery Storage project will add 88 megawatts (MW) and 352 megawatt-hours (MWh) of energy storage, while the Tranquillity Solar Facility will add 72 MW and 288 MWh of energy storage.
“These co-located solar and storage projects are a first of their kind for Southern Power,” Southern Power President Bill Grantham said. “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.”
Rosendin Electric built the facilities while 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.
These projects align with Southern Power’s growth strategy of developing and acquiring projects covered by long-term contracts with strong credit-worthy counterparties.
Southern Power, a subsidiary of Southern Company, is a leading U.S. wholesale energy provider for municipalities, electric cooperatives, investor-owned utilities, and other energy customers.
