The Xiangjiaba Dam (simplified Chinese: 向家坝; traditional Chinese: 向家壩; pinyin: Xiàngjiābà) is a large gravity dam on the Jinsha River, a tributary of the Yangtze River in Yunnan Province and Sichuan Province in southwest China. The facility has eleven Francis turbines, four with a capacity of 812 MW and four rated at 800 MW and three with 450 MW, totalling an installed capacity of 7,750 MW.[2] Xiangjiaba Dam is China's fourth-biggest hydropower station following Three Gorges Dam, Baihetan Dam and Xiluodu Dam. Construction started on November 26, 2006, and its first generator was commissioned in October 2012.[3] The last generator was commissioned on July 9, 2014.[4]
