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.

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
