Solar Energy Generating Systems (SEGS) in California, with the combined capacity from three separate locations at 354 megawatts, is now the world's second largest solar thermal energy generating facility, after the commissioning of the even larger Ivanpah facility in 2014. It consists of nine solar power plants in California's Mojave Desert, where insolation is among the best available in the United States. SEGS I–II (44 MW) are located at Daggett, SEGS III–VII (150 MW) are installed at Kramer Junction, and SEGS VIII–IX (160 MW) are placed at Harper Lake. NextEra Energy Resources operates and partially owns the plants located at Kramer Junction. On January 26, 2018, the SEGS VIII and IX at Harper Lake were sold to renewable energy company Terra-Gen, LLC. A tenth plant had been in construction and SEGS XI and SEGS XII had been planned by Luz Industries, but the developer filed for bankruptcy in 1992, because it was unable to secure construction financing.
Nevada Solar One is a concentrated solar power plant, with a nominal capacity of 64 MW and maximum steam turbine power output up to 72 MW net (75 MW gross), spread over an area of 400 acres (160 ha). The projected CO2 emissions avoided is equivalent to taking approximately 20,000 cars off the road. The project required an investment of $266 million USD, and the project officially went into operation in June 2007. Electricity production is estimated to be 134 million kilowatt hours per year.
The Andasol solar power station is a 150-megawatt (MW) concentrated solar power station and Europe's first commercial plant to use parabolic troughs. It is located near Guadix in Andalusia, Spain, and its name is a portmanteau of Andalusia and Sol. The Andasol plant uses tanks of molten salt as thermal energy storage to continue generating electricity, irrespective of whether the sun is shining or not.
According to preliminary data from the US Energy Information Administration, renewable energy accounted for about 11% of total primary energy consumption and about 17% of the domestically produced electricity in the United States in 2018. Hydroelectric power is currently the largest producer of renewable electricity in the country, generating around 6.5% of the nation's total electricity in 2016 as well as 45.71% of the total renewable electricity generation. The United States is the fourth largest producer of hydroelectricity in the world after China, Canada and Brazil.
The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix, completed in 2013. When commissioned it was the largest parabolic trough plant in the world and the first U.S. solar plant with molten salt thermal energy storage. Built by the Spanish company Abengoa Solar, it has a total capacity of 280 megawatts (MW) gross, from two 140 MW gross (125 MW net) steam turbine generators, which is enough to power 70,000 homes while avoiding around 475,000 tons of CO2 every year. Its name is the Spanish term for "sunny spot".
The PS20 solar power plant (PS20) solar power plant is a solar thermal energy plant in Sanlucar la Mayor near Seville in Andalusia, Spain. It was the world's most powerful solar power tower until the Ivanpah Solar Power Facility in California became operational in 2014. The 20 megawatt (MW) solar power tower produces electricity with large movable mirrors called heliostats.
Concentrated solar power systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight onto a small area. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine connected to an electrical power generator or powers a thermochemical reaction.
Torresol Energy is a company dedicated to developing renewable energy and alternative energies, focusing on concentrated solar energy. It is based in the city of Getxo in Biscay Province (Vizcaya), in the Basque Country of northern Spain.
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 50% by 2030. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
Solar power in New Mexico in 2016 generated 2.8% of the state's total electricity consumption, despite a National Renewable Energy Laboratory (NREL) projection suggesting a potential contribution three orders of magnitude larger.
Shams Solar Power Station is a concentrating solar power station near Madinat Zayed, Abu Dhabi, the United Arab Emirates. The solar power station is located approximately 120 kilometres (75 mi) southwest of Abu Dhabi and 6 kilometres (4 mi) from Madinat Zayed on the road from Tarif to the Liwa Oasis. It became operational on 17 March 2013.
The Valle Solar Power Station is a two adjacent twin 50 MW solar thermal power plants in San José del Valle, Cádiz, Spain. The station generates power using parabolic trough technology. It became operational in January 2012. The Valle plant is owned by Torresol Energy, a joint venture between SENER (60%) and the Abu Dhabi Future Energy Company (40%). It was built by SENER between December 2009 and December 2011, at a cost of €540 million (US$700 million).
The Extresol Solar Power Station is a 150 megawatt (MW) commercial concentrated solar thermal power plant, located in Torre de Miguel Sesmero in the province of Badajoz, Extremadura, Spain.
Alvarado I is a large solar thermal power station in Alvarado, province of Badajoz, in Extremadura, Spain. Construction on the plant commenced in December 2007 and was completed in July 2009, when commercial operations began. With an installed capacity of 50 MWe, it is one of the largest solar thermal power stations in the world.
Holaniku at Keahole Point is a 2MW micro-scaled concentrated solar power plant in the Kona District of the island of Hawaiʻi. It is located in the Natural Energy Laboratory of Hawaii at Keahole Point.
The Blythe Mesa Solar Power Project, also known as the Blythe Solar Energy Center, is a 235 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.
