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.[2] [3] As of April 2017 the dam is completed.[4] First turbine was commissioned in December 2019, followed by second in May 2020 and third and fourth in August 2020. The last two units were commissioned in February 2021.[5]
The lower reservoir is formed by a 63.90NaN0 tall and 4800NaN0 long concrete-face rock-fill dam (CFRD), with a storage capacity of 109440000NaN0 of which 86700000NaN0 is active (or 'usable') for pumping. The upper reservoir is formed by a CFRD as well, which is 114.20NaN0 tall and 3300NaN0 long, withholding a 105980000NaN0 man-made lake. The normal elevation of the lower reservoir is 339.30NaN0 and the upper 9610NaN0. This difference in elevation affords a rated hydraulic head of 5990NaN0. The power station is located underground near the bank of the lower reservoir and contains six 300 MW Francis pump turbine-generators.[6]
