Clean Power Alliance Board OKs PPAs With Berkshire Hathaway Energy Unit

The Clean Power Alliance Board of Directors has approved two 20-year power purchase agreements with BHE Renewables, a subsidiary of Berkshire Hathaway Energy.

The solar plus storage projects are co-located at BHE Renewables’ Solar Star 3 and Solar Star 4 facilities in Kern County and will add both renewable energy and battery storage capacity to CPA’s growing fleet of projects, reducing emissions and increasing power reliability of California’s electrical grid.

This is the first time CPA has contracted with BHE Renewables, which operates in 11 states and develops, owns and operates solar, wind, geothermal and hydroelectric power plants. CPA is slated to begin receiving energy from Solar Star 3 and Solar Star 4 in 2025.

Each of the projects will provide 24 MW of solar power generation and 23 MW of four-hour battery energy storage.

The two PPAs are the 45th and 46th long term contracts CPA has signed to date, totaling 2,642 MW of renewable energy and 1,934 MW of battery energy storage in its overall energy portfolio.

The State of California announced a milestone earlier this year when it surpassed 10,000 MW of available battery storage capacity. The state projects 52,000 MW of capacity is needed by 2045 to reach 100% clean electricity. CPA’s continued investments in storage are helping move the state closer to its clean energy goals.

CPA currently serves more than three million residents and businesses in 35 communities throughout Los Angeles and Ventura counties.

In October 2025, the number of communities will increase to 38 when the cities of La Cañada Flintridge, Lynwood, and Port Hueneme join CPA service. CPA began providing clean renewable energy to its Southern California customers in 2018.
