CHN Energy announced that the first unit of the Dadu River Shuangjiangkou Hydropower Station, the world's highest dam, has been successfully connected to the grid for power generation, adding new support to the clean energy supply system in Southwest China and the realization of China's "dual carbon" goals.
The Shuangjiangkou Hydropower Station, a national key energy project located in Jinchuan County, Sichuan Province, serves as the controlling reservoir and leading hydropower station on the upper reaches of the Dadu River. Primarily focused on power generation while also providing flood control, the station has a total installed capacity of 2,000 MW and an average annual power generation of 7.7 billion kWh.
According to reports, the dam of the Shuangjiangkou Hydropower Station is a gravel soil core rockfill dam with a maximum height of 315 meters, making it the world's highest dam. The total filling volume of the dam exceeds 46 million cubic meters. Currently, the project has completed its second-phase water storage, fully meeting the conditions for unit power generation. The first unit has successfully achieved the goal of grid-connected power generation, with overall operating conditions stable, safe, and controllable.
"The Shuangjiangkou Reservoir has annual regulation capacity with a total storage capacity of 2.9 billion cubic meters. After operation, it will bring an average annual power gain of 6.6 billion kWh to downstream cascade hydropower stations, enhance the peak-shaving and frequency-regulation capabilities of the Sichuan power grid, optimize the power system's energy structure, and improve flood control standards across the entire Dadu River basin, becoming an important flood control safety barrier on the upper reaches of the Yangtze River," said a relevant official from CHN Energy.
With the commissioning of the Shuangjiangkou Hydropower Station, CHN Energy's installed capacity of hydropower and new energy in the Dadu River basin has reached nearly 15,000 MW, delivering over 60 billion kWh of clean energy annually. This can save approximately 17 million tons of coal and reduce carbon dioxide emissions by about 46 million tons, supporting the economic development of the Chengdu-Chongqing region.
