Solar Energy Generating Systems 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 are located at Daggett, SEGS III–VII are installed at Kramer Junction, and SEGS VIII–IX are placed at Harper Lake. NextEra Energy Resources operates and partially owns the plants located at Kramer Junction and Harper Lake.
