TAIYUAN, March 21 -- In the mountainous region of Daixian County, north China''s Shanxi Province, a pumped-storage power station with a total installed capacity of 1.4 million kilowatts
The Fengning Pumped Storage Power Station, the world's largest facility of its kind, has commenced full operations with the commissioning of its final variable-speed unit on December 31.
The “Energy Storage No. 1” project utilizes the caverns of an abandoned salt mine, reaching up to 600 meters of depth, as its gas storage facility. This allows for a gas storage volume of nearly 700,000 cubic meters, translating into a single unit power output of up to 300 MW and a storage capacity of 1,500 MWh.
The world's biggest pumped storage plant, the Fengning Power Station, went into full service at the end of the year, supporting 10 gigawatts of solar- and wind-powered generation in China's Hebei Province, near Beijing and Tianjin.
This allows for a gas storage volume of nearly 700,000 cubic meters, translating into a single unit power output of up to 300 MW and a storage capacity of 1,500 MWh. The system conversion efficiency is about 70%. It can store energy for eight hours and release energy for five hours every day, and generate about 500 GWh of electricity annually.
Namely, the plant's storage capacity will allow for up to 2.8 GWh of electricity per full charge, with an estimated annual 330 charge-discharge cycles. CAES is considered a mature technology for deep decarbonization and GW-level deployment with technological components that are proven and used in industry for decades.
When fully charged, the upper reservoir can store enough energy to power the plant at full capacity for 10.8 hours, equivalent to nearly 40 GWh. This makes Fengning the most significant pumped storage facility in North China in terms of balancing renewable energy output.
