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 under construction on the Jinsha River, a tributary of the Yangtze River) in Sichuan and Yunnan provinces, in the southwest of China. The dam is a 277 m tall double-curvature arch dam with a crest elevation of 827 m. Its width at the base (crest) will be 72 (13) m.
The facility will generate power by utilizing 16 turbines, each with a generating capacity of 1,000 MW, taking the generating capacity to 16,000 MW. In terms of generating capacity, it will be the second largest hydroelectric power plant in the world, after the Three Gorges Dam. When finished, it will be the third largest dam in China and the fourth in the world, in terms of dam volume. Construction on the dam began in 2008 and is expected to be complete in 2021.
