It is the largest hydropower station in the world, with major functions including flood control, power generation, shipping and water resource utilization. The total installed capacity of the station is 22,500 MW, including 32 units with a single capacity of 700 MW and another two units with a single capacity of 50 MW.
The Gezhouba Hydropower Station is located at the end of the Three Gorges section of the Yangtze River in Yichang City. It is the first large-scale hydropower project constructed on the main stream of the Yangtze River, with a comprehensive function of power generation and waterway improvement. It has 22 units with a total capacity of 2,735 MW. Its first unit was put into operation on July 30, 1981, and the project was fully completed in 1988.
Xiluodu Hydropower Station is located at the Jinsha River Gorge, where Leibo County of Sichuan Province and Yongshan County of Yunnan Province are bordering. The electricity it generates is mainly supplied to east China and south China. A total of 18 hydroelectric generating units with a single-unit capacity of 770 MW are installed in the power station. The total installed capacity of the power station is 13,860 MW, and the highest dam is 285.5 meters. It is the world's first high-arch mega hydropower station with double-digit gigawatt capacities, which won the FIDIC Project Awards for the Year 2016. The Station was officially put into operation at the end of 2005, and the first units began power generation in July 2013. All of Its 18 units were put into operation at the end of June 2014.
Xiangjiaba Hydropower Station is located at the outlet of Jinsha River Gorge, at the junction of Yibin City, Sichuan Province and Shuifu City, Yunnan Province. The Station was designed primarily for electricity generation, and has integrated functions including flood control, shipping, irrigation, and sand control. It is equipped with eight hydropower generating units with a single capacity of 800MW and the world's largest vertical shiplift with a lifting height of 114.2 meters. Its construction officially kicked off in November 2006, and the first unit was put into operation in November 2012. All of its units began to generate electricity in July 2014. On May 26, 2018, the shiplift was opened to traffic on a trial base.
