Ivanpah Solar Power Facility

The Ivanpah Solar Electric Generating System is a concentrated solar thermal plant in the Mojave Desert. It is located at the base of Clark Mountain in California, across the state line from Primm, Nevada. The plant has a gross capacity of 392 megawatts (MW). It deploys 173,500 heliostats, each with two mirrors focusing solar energy on boilers located on three centralized solar power towers. The first unit of the system was connected to the electrical grid in September 2013 for an initial synchronisation test. The facility formally opened on February 13, 2014. In 2014, it was the world's largest solar thermal power station.

Crescent Dunes Solar Energy Project

The Crescent Dunes Solar Energy Project is a 110 megawatt (MW) net solar thermal power project with 1.1 gigawatt-hours of energy storage, located near Tonopah, about 190 miles (310 km) northwest of Las Vegas. It is the first utility-scale concentrating solar power (CSP) plant with a central receiver tower and advanced molten salt energy storage technology from SolarReserve. The project, developed by SolarReserve and owned by Tonopah Solar Energy, LLC. was anticipated to cost less than $1 billion. EPC Contractor was ACS Cobra, which carried out the engineering design, procured the equipment and materials necessary, and then constructed and delivered the facility to Tonopah Solar Energy. Planned energy output was 500 GW·h annually.

Solar Energy Generating Systems

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.

PS10 solar power plant

The PS10 Solar Power Plant, is the world's first commercial concentrating solar power tower operating near Seville, in Andalusia, Spain. The 11 megawatt (MW) solar power tower produces electricity with 624 large movable mirrors called heliostats. It took four years to build and so far cost €35 million (US$46 million). PS10 produces about 23,400 megawatt-hours (MW·h) per year, for which it receives €271 (US$360) per MW·h under its power purchase agreement, equating to a revenue of €6.3 million per year.

Solana Generating Station

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".

Nevada Solar One

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 annually. 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.

Mojave Solar Project

The Mojave Solar Project (MSP) is a concentrated solar power (CSP) facility in the Mojave Desert in California, about 20 miles (32 km) northwest of Barstow. Surrounding the hamlet of Lockhart, Mojave Solar is adjacent to Harper Lake and the SEGS VIII–IX solar plant. The site was originally reserved for the planned, never built, SEGS IX and XII. For 15 years following its construction in 1990, this was the largest commercial solar power plant in the world, generating around 160 megawatts at its peak. It is one of three separately owned sites within 40 miles of one another, that make up the nine solar fields in the Solar Electric Generating System (SEGS #1 and 2 are at Daggett, and #3 through 7 are at Kramer Junction). Harper Lake was the last of these built, and is designated as SEGS #8 and 9. It is still online, but has been surpassed by other newer facilities, including the Mojave Solar Project. MSP, with a combined nameplate capacity of 280 MW (net 250 MW), is made of two, independently-operable, solar fields. The power plant cost an estimated $1.6 billion in total and entered commercial operation in December 2014. The developer, Abengoa, has successfully secured a $1.2 billion loan guarantee from the US government for the project. The plant is expected to generate 617,000 MWh of power annually, enough power for more than 88,000 households and to prevent the emission of over 430 kilotons of CO2 a year. Pacific Gas & Electric has agreed to a 25-year power purchase agreement.

Solnova Solar Power Station

The Solnova Solar Power Station is a large CSP power station made up of five separate units of 50 MW each. The facility is part of the Solucar Complex, in Sanlúcar la Mayor, in Spain, the same area where the PS20 solar power tower is also located. With the commissioning of the third 50 MW unit, the Solnova-IV in August 2010, the power station ranks as one of the largest CSP power stations in the world.

Andasol Solar Power Station

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.

Genesis Solar Energy Project

The Genesis Solar Energy Project is a concentrated solar power station located in the Mojave Desert on 1,920 acres (780 ha) of Bureau of Land Management land, in eastern Riverside County, California. The plant is owned/managed by Genesis Solar, LLC, a subsidiary of NextEra Energy Resources, LLC. The Genesis Solar Energy Project is located about 25 miles (40 km) west of Blythe, in the Lower Colorado River Valley. The plant was built in the Colorado Desert along an ancient trade route that native people had traveled for thousands of years. The route traversed the Sonoran Desert and enabled trade between the Colorado River and the coast.
