Solar Energy Generating Systems (SEGS) is a concentrated solar power plant in California, United States. With the combined capacity from three separate locations at 354 megawatt (MW), it was once the world's second largest solar thermal energy generating facility, until the commissioning of the even larger Ivanpah facility in 2014. It consisted of nine solar power plants in California's Mojave Desert, where insolation is among the best available in the United States.
Solar power in California includes utility-scale solar power plants as well as local distributed generation, mostly from rooftop photovoltaics. It has been growing rapidly because of high insolation, community support, declining solar costs, and a Renewable Portfolio Standard which requires that 33% of California's electricity come from renewable resources by 2020, and 60% by 2030. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
Sierra SunTower was a 5 MW commercial concentrating solar power (CSP) plant built and operated by eSolar. The plant is located in Lancaster, California. As of mid-September, 2022, the two towers that were the center of the facility are no longer standing. The rest of the plant, however, is still present.
The Blythe Mesa Solar Power Project, also known as the Blythe Solar Energy Center, is a 485 megawatt (MWAC) photovoltaic power plant near the city of Blythe in Riverside County, California. It occupies about 2,000 acres of public land managed by the Bureau of Land Management in the Mojave Desert. The construction uses CdTe thin film panels from the U.S. firm First Solar, and the majority of the output is being sold to Kaiser Permanente and Southern California Edison under 20-year power purchase agreements.
The 21 megawatt Blythe Photovoltaic Power Plant is a photovoltaic (PV) solar project in California. It is located in Blythe, California, in Riverside County about 200 miles (320 km) east of Los Angeles. Commercial operation began in December 2009. Electricity generated by the power plant is being sold to Southern California Edison under a 20-year power purchase agreement. Another 20 MW plant called NRG Solar Blythe II came online in April 2017.
The Copper Mountain Solar Facility is a 802 megawatt (MWAC) solar photovoltaic power plant in Boulder City, Nevada, United States. The plant was developed by Sempra Generation. When the first unit of the facility entered service on December 1, 2010, it was the largest photovoltaic plant in the U.S. at 58 MW. With the opening of Copper Mountain V in March 2021, it again became the largest in the United States. It is co-located with the 64 MW Nevada Solar One, 150 MW Boulder Solar, and 300 MW Techren Solar projects in the Eldorado Valley, thus forming a more than 1 gigawatt (GW) solar generating complex. By comparison, generating capacity at the nearby Hoover Dam is about 2 GW.
The Space Coast Next Generation Solar Energy Center is a 10 megawatt (MW) solar photovoltaic (PV) facility at the Kennedy Space Center, Florida. Commissioned in April 2010, the center is the result of a partnership between NASA and Florida Power & Light. The facility has approximately 35,000 solar photovoltaic panels from SunPower covering an area of 60 acres. The facility provides slightly less than one percent of the power needed to keep Kennedy Space Center up and running.
The Desert Sunlight Solar Farm is a 550 megawatt (MWAC) photovoltaic power station approximately six miles north of Desert Center, California, United States, in the Mojave Desert. It uses approximately 8.8 million cadmium telluride modules made by the US thin-film manufacturer First Solar.

The Antelope Valley Solar Ranch 1 (AVSR1) is a 230 megawatt (MWAC) photovoltaic power plant near Lancaster within Antelope Valley, in the western Mojave Desert, Southern California. It uses cadmium telluride modules made by the US thin-film manufacturer First Solar. The project was developed by First Solar and later bought by Exelon Corporation in 2011. The solar facility was fully commissioned in April 2014.
The Hatch Solar Energy Center is a 5.88 MWp (5.0 MWAC) photovoltaic power station. It was built by Blattner Energy using 84 dual-axis trackers and Amonix 7700 concentrator photovoltaics (CPV) panels, each of which contains 7,560 fresnel lens to concentrate sunlight 500 times onto multijunction photovoltaic cells. It was the largest CPV facility in North America when it was completed in 2011. The facility was subsequently repowered with SunPower panels that use high-efficiency monocrystalline silicon cells without concentration. The output is being sold to El Paso Electric, under a 25 year power purchase agreement (PPA). Annual electricity production is expected to be about 11,000 MW·h/year.
The Tenaska Imperial Solar Energy Center South is a 130 megawatt (MW) photovoltaic power plant built in Imperial County, California. Construction began in December 2011 and full commercial operation was achieved in November 2013. Power is sold to San Diego Gas & Electric on a 25-year agreement.
Campo Verde Solar Project is a 139-megawatt (MWAC) solar photovoltaic power station in Imperial County, California. The project was approved in December 2012. Construction began in early 2013 and was completed the same year. Designed and constructed by U.S. thin-film manufacturer First Solar, the plant uses nearly 2.3 million CdTe-PV modules. Campo Verde Solar was acquired in April 2013 by Southern Power and Turner Renewable Energy. First Solar acquired the project in 2012 from US Solar Holdings LLC, which had developed the project and negotiated the 139 MW PPA with SDG&E.
Mount Signal Solar, also known as Imperial Valley Solar Project, is a 794 MWp (614 MWAC) photovoltaic power station west of Calexico, California, United States, in the southern Imperial Valley, near the Mexican border. The facility is being developed and constructed by 8minutenergy Renewables in three phases, with two completed as of 2018. At full build-out, it will be one of the world's largest PV solar farms with a capacity of about 800 MWp (600 MWAC). The project has been supported by several environmental groups, as the power station was built on low productivity farmland.
