The Minghu Dam (, renamed the Takuan Dam, is a concrete
gravity dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. ...

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
