The Minghu Dam (Chinese: 明湖水庫; pinyin: Mínghú Shuǐkù, renamed the Takuan Dam,[2] is a concrete gravity dam on the Shuili River located 7 km (4.3 mi) north of Shuili Township in Nantou County, Taiwan. The dam was constructed to serve as the lower reservoir for the Minhu Pumped Storage Hydro Power Station. Sun Moon Lake serves as the upper reservoir.


The dam and the power plant was constructed in 1980 and opened on 1 August 1985.[3] Upon completion, it became Taiwan's first pumped-storage hydroelectricity power plant.[4][5]

Takuan Power Plant[edit]

The pumped-storage hydroelectricity power plant, officially named Takuan Power Plant, which sits near the left abutment of the dam and moves water between the two reservoirs to generate electricity. During periods of low demand, such as at night, when electricity is cheap, water is pumped to Sun Moon Lake. When energy demand is high, water is released down to the power station for power generation. This is accomplished by four 252 megawatts (338,000 hp) Francis pump-turbine-generators which are reversible and serve to both pump water and generate electricity. The power plant has an installed capacity of 1,008 megawatts (1,352,000 hp).

Mingtan Dam, located downstream serves as the lower reservoir for the Mingtan Pumped Storage Hydro Power Plant with an installed capacity of 1,602 megawatts (2,148,000 hp).[6][7]
