The Minghu Dam (Chinese: 明湖水壩; pinyin: Mínghú Shuǐbà, renamed the Takuan Dam,[1] 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 and the power plant was constructed in 1980 and opened on 1 August 1985.
[3][4] 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.
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.
