329: 29: 315: 253:(TEPCO). The power plant started operation in July 1988 with a capacity of 350 MW (one unit operational). The other two units entered operation in December 1991. The plant is one of the many large scale pure pumped-storage plants built in Japan since the 1970s to compensate for the increased penetration of base-load nuclear power and peak load from cooling and air-conditioning. 301: 264:, a rock-fill embankment dam at an altitude of 1054 m. The reservoirs can store 9,100,000 cubic metres (7,400 acre⋅ft) of water. Of that storage volume, 6,200,000 cubic metres (5,000 acre⋅ft) can be used for power generation. This is enough for about 7 hours of operation at full generation capacity, giving a total 508:
