Xiangjiaba Dam 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 last generator was commissioned on July 9, 2014. The output of the generating station is connected to
Three Gorges Dam by 190 million tonnes, sulfur dioxide by 2.29 million tonnes, and nitrogen oxides by 980,000 tonnes. The dam increased the Yangtze's barge capacity sixfold, reducing carbon dioxide emission by 630,000 tonnes. From 2004 to 2007, a total of 198 million tonnes of goods passed through the ship locks. Compared to using trucking, barges reduced carbon dioxide emission by ten million tonnes and lowered costs by 25%. Two hazards are uniquely identified with the dam. One is that sedimentation projections are not agreed upon, and the other is that the dam sits on a seismic fault. At current levels, 80% of
