January 4 (Renewables Now) - State Grid Corporation of China has put into operation a 3.6-GW pumped storage hydropower station in China’s Hebei province, the world’s largest one in terms of installed capacity.

Chinese state-owned electric utility and grid operator announced the commissioning of the Fengning complex during a conference last week. The capacity was brought online in time to serve the 2022 Beijing Winter Olympics next month.

Built at a total cost of CNY 19.2 billion (USD 3.02bn/EUR 2.67bn), the huge pumped storage facility is located in Hebei province’s Fengning County. The capacity was installed in two 1.8-GW phases that added a total of 12 pump generating sets of 300 MW each, accommodated in an underground powerhouse.

Engineering company China Gezhouba Group handled the construction process.

The complex is connected to the Zhangbei VSC-HVDC power grid and the North China 500kV power grid. It will operate as a peaking power plant to ensure the stable operation of the grid and balance electricity supplies from large wind and solar parks in Hebei and Inner Mongolia.

The Fengning pumped storage station will be run by State Grid Xinyuan Company, a subsidiary of State Grid Corporation of China.
