Yamagawa
Location: Kagoshima
Operator: Kyushu Electric Power Co Inc
Configuration: 1 X 30 MW
Operation: 1995
T/G supplier: MHI
Quick facts: The Fushime geothermal field on which Yamagawa GPP is located has been under exploration since the late 1970s by Japan Petrolium Exploration Co. Ltd (JAPEX) and its subsidiaries. The power station lies near the coast covering an area of 160,000 sq m, and many of the wells have been drilled outwards from the site, so that it draws energy from a much wider area. By 2000, 12 production wells (1500-2500m deep) and 4 reinjection wells (800-1300m deep) were in operation.
