Fengning Pumped Storage Power Station

The Fengning Pumped Storage Power Station is a pumped-storage hydroelectric power station about 145 km (90 mi) northwest of Chengde in Fengning Manchu Autonomous County of Hebei Province, China. Construction on the power station began in June 2013 and the first generator was commissioned in 2019, the last in 2021. Project cost was US$1.87 billion. On 1 April 2014 Gezhouba Group was awarded the main contract to build the power station. It was constructed in two 1,800 MW phases. Main construction was completed in late 2021, and became the largest pumped-storage power station in the world with an installed capacity of 3,600 MW. The 12th and final turbine began commercial operations in August 2024. The lower reservoir holds up to 66,150,000 m3 (53, 630 acre⋅ft) of water of which 41,480,000 m3 (33, 630 acre⋅ft) can be used for power generation. The upper reservoir withholds up to 48,830,000 m3 (39, 590 acre⋅ft) of water of which 40,610,000 m3 (32, 920 acre⋅ft) can be used for power generation. Water from the upper reservoir is sent to the underground power station down near the lower reservoir. The facility is designed to consume 8.71 TWh of electricity for pumping, and then generate 6.61 TWh, annually.
