The world’s largest utility scale solar project is
located in California.

The world’s largest utility-scale solar projects are located in California. The Solar Star projects are two distinct projects—Solar Star 1 and Solar Star 2—co-located in Kern and Los Angeles counties. Installed across 3,230 acres, the projects are comprised of 1.7 million SunPower monocrystalline silicon PV panels. The projects have a combined generating capacity of 579 megawatts and generate the electricity with no emissions or waste.

The first phase of the project was synchronized to the California Independent Systems Operator grid in October 2013. And the PV solar power plant went fully online on July 1, 2015.

The Solar Star projects are owned by BHE Renewables, a wholly owned subsidiary of Berkshire Hathaway Energy. The project was constructed and is operated by SunPower Corporation. Under a long-term power purchase agreement, the generated electricity will be delivered to Southern California Edison’s service territory.

  • The power plants have an automated cleaning process that is four times faster than manual cleaning methods and uses approximately 90 percent less water.
  • The Solar Star projects generate enough electricity to displace approximately 570,000 tons of carbon dioxide per year—the equivalent of taking nearly 108,000 cars off the road annually.
  • The projects have the capacity to power the equivalent of approximately 255,000 average California homes.
  • The projects are sited on previously disturbed agricultural land that has been fully reseeded to support regrowth of native vegetation and reduce the potential for blowing dust near the project sites.
  • Approximately 650 jobs were created during construction of the projects.
  • Approximately $500 million in positive regional economic impact result from the projects, with the majority recognized during construction.
