The Okutataragi Pumped Storage Power Station (奥多々良木発電所, Okutataragi hatsudensho) is a large pumped-storage hydroelectric power station in Asago, in the Hyōgo Prefecture of Japan. With a total installed capacity of 1,932 megawatts (2,591,000 hp),[1] it is one of the largest pumped-storage power stations in the world, and the largest in Japan. The facility is currently run by the Kansai Electric Power Company.[2]
Like most pumped-storage facilities, the power station utilizes two reservoirs, releasing and pumping as the demand rises and falls. Construction on the facility began in 1970 and was completed in 1974.
