Xiangjiaba Dam a ±800 kV HVDC link, the Xiangjiaba–Shanghai HVDC system, which transmits much of the power to Shanghai. Xiangjiaba Dam The Xiangjiaba Dam () 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 , totalling an installed capacity of . 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. The
Three Gorges Dam land were flooded. The flood affected more than 2.3 million people, killing 1,526. In early August 2009, the largest flood in five years passed through the dam site. The dam limited the water flow to less than per second, raising the upstream water level from 145.13 metres on August 1, 2009, to 152.88 on August 8, 2009. 4.27 cubic kilometres of flood water were captured and the river flow was cut by as much as 15,000 cubic metres per second. The dam discharges its reservoir during the dry season between December and March every year. This increases the flow rate
