On June165438+1October1day, 2023, the Xulong Hydropower Station on the Jinsha River, the largest hydropower station under construction in China, was successfully intercepted, marking that the project has entered the main project construction stage from the preliminary preparation stage.
Xulong Hydropower Station is located in Rongbatang County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, Deqin County, Diqing Tibetan Autonomous Prefecture, Yunnan Province, and Mangkang County, Qamdo City, Tibet. It is the hydropower station with the largest installed capacity approved by the state during the tenth five-year plan period. On June 7, 2022, it was officially approved by the National Development and Reform Commission, with a total installed capacity of 2.4 million kilowatts and an annual power generation of about 654.38+005 billion kWh.
The riverbed is cut off once, the upstream and downstream cofferdams store water all the year round, and the high and low diversion tunnels on the left bank discharge water. The standard of intercepting flow is 1 263.5 m3/s, which is 1.46% of the planned intercepting flow of 862.7 m3/s, and the length of intercepting dike is 1.654+0.68.
