The Huanggou Pumped Storage Power Station is a 1,200 MW pumped-storage hydroelectric power station currently under construction about 90km (60miles) north of Mudanjiang in Hailin County of Heilongjiang Province, China. Construction on the project began on 8 May 2014. The first generator is scheduled to be commissioned in January 2019 and the project complete in January 2020. The power station operates by shifting water between an upper and lower reservoir to generate electricity. The lower reservoir, Lianhua Reservoir, is located on the Mudan River and the upper reservoir is located in a valley above the north side of the lower reservoir. During periods of low energy demand, such as at night, water is pumped from Huanggou Lower Reservoir up to the upper reservoir. When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity. The process is repeated as necessary and the plant serves as a peaking power plant. It is operated by the State Grid Corporation of China.[1]
The lower Lianhua Reservoir is created by the 71.8m (235.6feet) tall and 902m (2,959feet) long Lianhua Dam, a rock-fill dam on the Mudan River. It can withhold up to 4180000000m2 of water. The upper reservoir is created by an 80m (260feet) tall and 744.2m (2,441.6feet) long concrete-face rock-fill dam. It can withhold up to 11610000m2 of water, of which 10280000m2 can be used for power production. Water from the upper reservoir is sent to the underground power station down near the lower reservoir through headrace/penstock pipes. The power station contains four 300 MW Francis pump turbines. The difference in elevation between the upper and lower reservoir affords a hydraulic head (water drop) of 434.50NaN0.[2]
