China’s CNNC Xinhua Hydropower Company has started construction on a 2.1 GW pumped-storage hydropower plant located in Ruoqiang County, Bayingolin Mongolian Autonomous Prefecture, in the Xinjiang Uygur Autonomous Region (north-western China).
The Ruoqiang pumped-storage hydropower project is expected to require an investment of CNY16.5bn (US$2.3bn) and to be completed by 2030. It will generate 2.6 TWh/year of power once completed, allowing the reduction of coal use by about 1.35 Mt and a reduction of CO2 emissions of more than 4 MtCO2/year.
China aims to build more than 200 pumped storage plants with a combined capacity of 270 GW by 2025. At the end of 2022, China’s pumped storage capacity reached 45.8 GW, a 26% increase compared to 2021 and a more than twofold increase compared to ten years earlier (20.3 GW in 2012).
