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, southwest China. The facility has eight Francis turbines, four with a capacity of 812 MW and four rated at 800 MW, totalling an installed capacity of 6,448 MW. Xiangjiaba Dam is China's third-biggest hydropower station following Three Gorges Dam and Xiluodu Dam. Construction started on November 26, 2006, and its first generator was commissioned in October 2012.[2] The last generator was commissioned on July 9, 2014.[3]

The output of the generating station is connected to a ±800 kV HVDC link, the Xiangjiaba–Shanghai HVDC system, which transmits much of the power to Shanghai.
