The Baihetan Dam (simplified Chinese: 白鹤滩大坝; traditional Chinese: 白鶴灘大壩; pinyin: Báihètān Dàbà) is a large hydroelectric dam on the Jinsha River, an upper stretch of the Yangtze River in Sichuan and Yunnan provinces, in southwest China.

The hydropower station is equipped with 16 hydro-generating units each having a capacity of 1 billion Watts, the world's largest turbines.

[8][6] In addition to power generation, the hydropower project also provides flood control, improved navigation, and sand blocking.

[9] On 20 December 2022, the formal completion of Baihetan Hydropower Station was achieved when the final hydro-generating unit was connected to the grid and began producing power.

[10] In terms of generating capacity, it is the second largest hydroelectric power plant in the world, after the Three Gorges Dam.

[15] The manufacturing of the first water guiding mechanism in the Baihetan Hydro-generator units was completed in Harbin, where it both passed inspection and was awarded approval on October 27, 2018.

[17] On June 28, 2021, the Baihetan Dam began generating electricity, when the project's first two turbines started operating.
