It uses the pumped-storage hydroelectric method to generate electricity. The plant has an installed capacity of {{convert|1224|MW}}.[1] Construction began in 2005 and the first generator was commissioned on 20 November 2014.[2][3] The second generator was commissioned on 26 December 2014 and the final two were commissioned in June 2015.[4] Design and operationWhen energy demand is high, water from the upper reservoir supplies the power station with four 306 MW reversible Francis pump turbine-generators to generate electricity. After the power is generated, the water is discharged into a lower reservoir in the valley. When energy demand is low and the upper reservoir needs to be replenished, the water can be pumped back up when the pump-generators reverse into pumps. The upper reservoir is situated at an elevation of {{Convert|1940|m}} and was formed by the construction of a {{Convert|62.5|m}} tall concrete-face rock-fill dam. It has a storage capacity of {{Convert|6660000|m3|acre.ft}}, of which {{Convert|6290000|m3|acre.ft}} can be used for power generation. The lower reservoir is formed by two gravity dams constructed of roller-compacted concrete. The upstream dam at a height of {{Convert|57|m}} and serves to trap sediment in the river which is the source of water for the power plant. The second gravity dam, located downstream, is {{Convert|69|m|}} tall and withholds the lower reservoir with a capacity of {{Convert|7170000|m3|acre.ft}} of which {{Convert|6360000|m3|acre.ft}} can be used for pumped-storage. The lower reservoir is located at an altitude of {{Convert|1400|m}}. The difference in elevation between the two reservoirs affords a hydraulic head (drop in water) of {{Convert|521|m}}. It is estimated that the plant will generate 2.007 billion kWh annually but consume 2.677 billion kWh pumping. Because pumping occurs during periods of low energy demand when there is a surplus and electricity is cheap, the plant is economical.[5][6][7] See also{{stack|{{Portal|China|Water|Renewable energy}}}}
