Jixi Pumped Storage Power Station
The Jixi Pumped Storage Power Station () is a pumped-storage hydroelectric power station currently under construction in Jixi County, Anhui Province, China. Studies were carried out in 2008 and construction began in December 2010. It is expected to last 6 years. As of April 2017 the dam is completed. First turbine was commissioned in December 2019, followed by second in May 2020 and third and fourth in August 2020. The last two units are scheduled for commissioning by March 2021. The pumped-storage power plant will operate by using two reservoirs to generate power, an  upper and a lower. During periods of high energy demand, water is released from the upper reservoir and sent to the power station to generate electricity. After power generation, the water is discharged into the lower reservoir. When energy demand is low, such as at night, water is pumped back up to the upper reservoir as stored energy. The process repeats as needed and the pump-generators serve the dual-role of both pumping and generating electricity. Forming the lower reservoir will be a tall and long concrete-face rock-fill dam (CFRD). Its storage capacity will be of which  is active (or 'usable') for pumping. The upper reservoir will be formed by a CFRD as well, this one will be tall and long, withholding a man-made lake. The normal elevation of the lower reservoir will be and the upper . This difference in elevation affords a rated hydraulic head of . The power station will be located underground near the bank of the lower reservoir and contain six 300 MW Francis pump turbine-generators.
