During periods of high energy demand, water from the Takase
Reservoir is released down to the power station. After received by the intake, water initially travels along two 8 metres (26 ft) diameter and 2,600 metres (8,500 ft) long head-race tunnels. At the terminus of these tunnels, they

When energy demand is low and therefore electricity less expensive, the turbines reverse and pump water from the lower reservoir back into the upper reservoir. This process repeats depending upon energy demand and water availability. Water released from the lower reservoir is used to power the

Construction on the complex began in 1971, concluded in 1978 and the power station was commissioned in 1980. The power plant has a 1,280 megawatts (1,720,000 hp) installed capacity and its upper reservoir is created by the

reservoir is due to the high levels of silt in the Takase River which cause the reservoir to reserve 79 percent of its capacity for this purpose. During operation, the upper reservoir only draws down 10 metres (33 ft).
