The Mingtan Pumped Storage Hydro Power Plant is the largest hydroelectric power plant in Taiwan. It uses Sun Moon Lake as the upper reservoir and Shuili River reservoir as lower reservoir. During high power demand, water used for power generation from Sun Moon Lake, as well as Shuili River, fills Mingtan Reservoir. During low demand, the water is pumped back upstream to the lake. This system can generate up to at peak production.
