State Grid Xinyuan Group Co., Ltd., a subsidiary of the State Grid Corporation of China has started operations of 3.6 GW Fengning Pumped Storage Power Station located in Fengning County, Hebei Province, near Beijing and Tianjin.
The facility comprises 12 reversible pump-turbine units, each with a 300 MW capacity, including two variable-speed units, for a total installed capacity of 3.6 GW. It was developed by State Grid Xinyuan Group Co., Ltd., a subsidiary of the State Grid Corporation of China, with a total investment of CNY 19.24 billion (US$ 2.6 billion). It is designed to generate 6.61 TWh annually while consuming 8.71 TWh of electricity for pumping, and it connects to the North China power grid via four 500 kV transmission lines.
Construction of the Fengning station started in June 2013, with the Gezhouba Group awarded the primary construction contract in April 2014. The project was executed in two phases, each comprising six 300 MW reversible pump-turbine units. In 2017, ANDRITZ Hydro secured a contract to deliver two variable-speed generators for the project's second phase. These generators feature a nominal capacity of 330 MVA in generator mode and 345 MVA in pump mode, highlighting the cutting-edge technology incorporated into the Fengning station.
