China has begun the construction of a 2.8 GW pumped-storage hydropower plant in Guinan County, Qinghai Province, western China. The project, which is expected to require an investment of CNY16bn (US$2.24bn) will have a maximum energy storage capacity of about 20 GWh. The power plant will comprise eight units with a capacity of 350 MW each and is scheduled to be completed by 2030. Once completed, it is expected to help reduce coal consumption by about 1.82 Mt/year and reduce emissions by about 4.55 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).
