ANDRITZ to supply four 350-MW pump-turbine units to China
International technology Group ANDRITZ has received an order from Shaanxi ZhenAn Pumped Storage Co. Ltd., a subsidiary of State Grid Corporation of China (SGCC), for the supply of four 350-MW reversible pump-turbines and motor-generators, together with auxiliary equipment for the ZhenAn pumped storage hydropower plant located in Shaanxi province, China.
ZhenAn, with a total installed hydropower capacity of 1,400 MW, will be the first pumped storage power station in northwest China. The contract value amounts to more than 100 million euros.
The four 350-MW reversible pump-turbine units will operate with a water head of 440 m. The first unit will be commissioned by the end of March 2023, and all units will be put into commercial operation by the end of December 2023. After completion, ZhenAn will be used for peak regulation, frequency regulation, and as synchronous condenser. In addition, it will serve as emergency standby reserve and black-start capacity for the Shaanxi power grid.
ANDRITZ has a long history in pumped storage hydropower plants, starting with supply of the generating units for the world’s first commercial pumped storage plant – Niederwartha in Germany in 1929, and has continued to provide groundbreaking pumped storage technology ever since. Germany’s largest pumped storage plant, Goldisthal, was the first outside Japan to be equipped with variable-speed units. One of the latest contracts includes supply of the first variable-speed pump-turbines for the Fening II pumped storage plant in China. Award of the contract for ZhenAn is further proof of ANDRITZ’s strong position in pump-turbine technology.
