The Guanyinyan dam is under construction gravity dam on the Jinsha Jiang (Chinese. Designation for the upper reaches of the Yangtze River ), 30 km southwest of Panzhihua on the border of the provinces of Yunnan and Sichuan in the PRC. The dam is used for energy generation and flood protection. Construction began in 2008 and in 2010 the river was diverted. The first generator should be operational in 2015 and the entire hydropower plant in 2016 . Upon completion, the power plant will have a nominal output of 3000 MW, which will consist of five Francis turbines , each with a 600 MW generator .
