Location: Kern County, CA
This 50.1-MW wind project, which expands Terra-Gen, LLC’s Voyager Wind IV facility, is located in Kern County, California. Since coming online in 2020, Voyager IV has created numerous construction jobs and positions while delivering wind power to California and CleanPowerSF customers.
OASIS
Energy Type: Wind
Location: Kern County, CA
This 60.3-MW wind project, called Oasis wind, is located in Mojave, California. The Oasis wind project began generating power for CleanPowerSF under a 15-year agreement when the project became operational in September 2021.
BLYTHE SOLAR IV
Energy Type: Solar plus storage
Location: Blythe, CA
Blythe Solar IV, a 62.5 MW solar photovoltaic and 47 MW battery storage center in Blythe, CA, that came online and began serving CleanPowerSF customers in Fall 2020 under a 20-year power purchase agreement. A subsidiary of NextEra Energy Resources developed, owns and operates the project, which created approximately 150 construction jobs.
MAVERICK SOLAR 6
Energy Type: Solar plus storage
Location: Desert Center, CA
Maverick Solar 6 is a 100-megawatt solar photovoltaic and 50 MW battery storage facility built near Desert Center, a community east of Palm Springs.
