Southern Power has announced plans to build 160MW of battery-based energy storage facilities at two of its solar farms in California, US.
The company has secured two 20-year power purchase agreements from Southern California Edison (SCE) for the energy storage projects.
The projects will be constructed at Southern Power’s Tranquillity Solar Facility and Garland Solar Facility, which were commissioned in 2016.
At the Garland Solar Facility in Kern County, Southern Power is planning to add 88MW and 352MWh of energy storage.
A 72MW and 288MWh of energy storage will be added to the Tranquillity Solar Facility in Fresno County, California.
Southern Power will own the facilities in partnership with AIP Management and Global Atlantic Financial Group.
AIP Management and Global Atlantic Financial Group also own ownership interests in the Garland and Tranquillity solar facilities.
By providing SCE and the California ISO (CAISO) with additional flexible resource capacity, the battery-based energy storage additions are expected to enhance California’s grid reliability.
Southern Power president Bill Grantham said: “These projects will be two of the first co-located solar and storage projects operating in the California market.
“We’re excited to be a part of the effort to enhance California’s grid reliability.
“The addition of these storage resources to our clean energy portfolio is a great strategic fit for our business and will further position Southern Power to meet our customers’ needs as the energy industry continues to evolve.”
Southern Power and its subsidiaries, own or operate 52 facilities operating or under development in 13 states with more than 12,080MW of generating capacity.
The facilities are located in Alabama, California, Delaware, Georgia, Kansas, Maine, Nevada, New Mexico, North Carolina, Oklahoma, Texas, Washington and West Virginia.
