SEGS solar power plant,California,USA. There are nine solar energy generating systems (SEGS) located in California's Mojave desert,USA. This Kramer Junction site,where five (SEGS III–VII,built 1986-1988) are located,receives around 340 days of sunshine per year. The parabolic mirrors track the Sun across the sky and focus its rays onto tubes containing a synthetic oil. The oil reaches temperatures of 400 degrees Celsius,and is used to boil water for steam turbine generators. Each Kramer Junction array produce 30 megawatts (MW) of power,a total of 150 MW,enough to supply 50,000 homes |
