Solar Electric Generating Systems power plant at Harper Lake, Mojave desert, California, USA, the largest solar plant in the world. It consists of nine solar fields among three nearby sites (Daggett, Kramer Junction, and Harper Lake) that together have a combined power generating capacity of 354 MW. A long parabolic reflecting trough concentrates sunlight onto a tube running above the trough that is filled with thermal oil that becomes hot and is used to heat steam for a standard turbine generator. A complete system consists of many such troughs laid out over a large area. (2008)
