Baihetan Dam

The Baihetan Dam () is a large hydroelectric dam on the Jinsha River, an upper stretches 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, and a width of 72 m at the base and 13 m at the crest. It is considered the last large hydropower project in China to be completed since a series of projects starting with the Three Gorges Dam, the third largest dam in China and the fourth in the world, in terms of dam volume.
Power generation.
The facility will generate power by utilizing 16 turbines, each with a generating capacity of , taking the generating capacity to . In terms of generating capacity, it will be the second largest hydroelectric power plant in the world, after the Three Gorges Dam.
Construction.
Surveying of the dam site was done in 1992. The dam was originally scheduled to be constructed between 2009 and 2018. Actual construction started in 2017. The reservoir started filling in April 2021, with the dam to start partial electricity generation in July of the same year. By July 2022, the dam should be fully operational. Experts have noted the 4-year construction period as being exceptionally fast for a project of its type.
