The Guanyinyan Dam is an under construction gravity dam on the Jinsha River 30 km (19 mi) southwest of Panzhihua on the border of Yunnan and Sichuan Provinces in China. The purpose of the dam is hydroelectric power generation and flood control. Construction on the dam started in 2008 and the river was diverted by 2010. The first generator should be operational in 2015 and the entire power station in 2016. When complete, the dam will support a 3,000 MW power station consisting of five 600 MW Francis turbine generators.
The Guanyinyan Dam will be a 159 m (522 ft) tall and 1,158 m (3,799 ft) long gravity dam. Of the dam's length, 838 m (2,749 ft) will be roller-compacted concrete and 320 m (1,050 ft) will be rock-fill embankment with this portion having a maximum height of 71 m (233 ft). The crest elevation of the dam will be 1,141 m (3,743 ft) above sea level and contain the power plant at the toe of its body. A spillway and two discharge openings are also included in the design.
