NANJING, Oct. 29 (Xinhua) — A pumped storage power plant (PSP) with the world's tallest dam entered full operation Tuesday in Jiangsu Province, one of China's most economically developed regions in eastern China.
The new pumped storage power plant is located in the city of Juzhong and was built by a subsidiary of the State Grid Corporation of China. Its total installed capacity is 1.35 GW, with an annual electricity output of 1.35 billion kWh when operating at full capacity.
The upper reservoir dam, which can hold up to 17.07 million cubic meters of water, is 182.3 meters high, which is almost equal to the height of a 60-story building and makes it the tallest pumped storage dam in the world.
Last summer, Jiangsu Province's power grid load repeatedly reached historic highs, at some points reaching 156 million kW. At the same time, the province is experiencing rapid growth in the installed capacity of its local power grid, fueled by new energy sources. This also creates a need for pumped storage power plants (PSPPs), which are designed to compensate for the instability and unevenness of power supply provided by wind and solar power plants by generating electricity at peak demand.
Since 2021, 78 pumped storage power units with a total capacity of 44.53 GW have been commissioned by the State Grid Corporation of China. -0-
