Solar Energy Generating Systems - Wikipedia, the free encyclopedia

Solar Energy Generating Systems - Wikipedia, the free encyclopedia: Solar Energy Generating Systems (SEGS) is the largest solar energy generating facility in the world. 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 (34°51′45″N 116°49′45″W), SEGS III–VII (150 MW) are installed at Kramer Junction, and SEGS VIII–IX (160 MW) are placed at Harper Lake.(35°02′N 117°21′W)[1] NextEra Energy Resources operates and partially owns the plants located at Kramer Junction and Harper Lake.

The plants have a 354 MW installed capacity, making it the largest installation of solar plants of any kind in the world.[1] The average gross solar output for all nine plants at SEGS is around 75 MWe — a capacity factor of 21%. In addition, the turbines can be utilized at night by burning natural gas.
NextEra claims that the solar plants power 232,500 homes and displace 3,800 tons of pollution per year that would have been produced if the electricity had been provided by fossil fuels, such as oil.[2]
The facilities have a total of 936,384 mirrors and cover more than 1,600 acres (6.5 km2). Lined up, the parabolic mirrors would extend over 229 miles (370 km).
