The Liyuan Dam is a concrete-face rock-fill dam on the Jinsha River on the border of Yulong County and Shangri-La County, Yunnan Province, China. The dam has an associated hydroelectric power station with a 2,400 MW power station containing 4 x 600 MW generators. Construction on the river diversion for the dam began in 2008.[1][2] It began to impound its reservoir in November 2014 and on December 28, 2014 the first generator was commissioned.[3][4] The second generator was commissioned in July 2015.[5]
