Abstract
The 52 MW Heber geothermal power plant was completed in August, 1985 in Imperial Valley, California and has been successfully operating since then. This power plant is not only the first large capacity hot water type geothermal power plant in U.S.A but also the first double flash cycle geothermal power plant in U.S.A. The mixed pressure turbine, air-cooled generator and high-efficiency steam gathering equipments were designed and manufactured by Mitsubishi reflecting the experience in the Hatchobaru 55MW double flash geothermal power plant in Japan, which is the first double flash geothermal power plant in the world. Successively, the second 17MW double flash geothermal power plant started commercial operation in December, 1985 in Beowawe, Nevada. This power plant had been completed in 14 months including engineering, manufacturing, construction and trial operation. For this short completion a large capacity module turbine called MODULAR-25 was adopted for the first time.
