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 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.[3] It is considered the last large hydropower project in China to be completed since a series of projects starting with the Three Gorges Dam,[4] 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 1.0 GW, taking the generating capacity to 16,000 MW.[5] In terms of generating capacity, it will be the second largest hydroelectric power plant in the world, after the Three Gorges Dam.[6]
Construction[]
Surveying of the dam site was done in 1992.[7] The dam was originally scheduled to be constructed between 2009 and 2018.[8] Actual construction started in 2017.[9] 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.[10] Experts have noted the 4-year construction period as being exceptionally fast for a project of its type.[11]
On June 28, 2021, the Baihetan Dam began generating electricity, when the project's first two turbines started operating.[12] The third turbine followed in July and the fourth in November.[13]
