Shiobara Pumped Storage Plant
The Shiobara Pumped Storage Power Station (塩原発電所) is a pumped-storage hydroelectric power station in Nasushiobara, in the Tochigi Prefecture of Japan. It has a total installed capacity of 900 megawatts (1,200,000 hp). The power plant started operation in 1994.[2]

Like most pumped-storage facilities, the power station uses two reservoirs, releasing and pumping as the demand rises and falls. The upper reservoir is contained by the Yashio Dam, a rock-fill dam. The lower reservoir is contained by the Sabigawa Dam, a concrete gravity dam.[1][3]
The power station employs three 300 MW pumping/generation units. The first 2 units started operation on 24 June 1994 and the third unit was started on 16 June 1995.[4]
