Japan - Miboro Hydroelectric Project (English)

The Miboro Hydroelectric Project for Japan is being constructed by the Electric Power Development Company, Inc. (EPDC). The Miboro Project consists of a rock-fill dam with solid clay core, an underground powerhouse with an installed capacity of 215 MW in two units and a step-up substation. The dam is located at Shirakawa on the Sho river, near the west coast of the main island of Japan. It will hold about 330 million cubic meters of useful water storage. The head on the generating units will be 192 meters. The units will discharge into a tunnel about 8 km long in which the water will be returned to the main stream of the Sho river upstream of the intake for an existing power plant owned by the Kansai Power Company. Annual energy generation by the Miboro Station under median hydro conditions will be about 545 million kwh. The project will make a sizeable and useful contribution toward the final solution of the electric power supply shortages which Japan has been experiencing since the end of the war.
