The primary purpose of the dam is hydroelectric power generation, with its 355 MW power station located 14.5 km to the southeast of the dam.[1][2] The difference in elevation between the reservoir and power station affords a hydraulic head (water drop) of 177 m (581 ft).
Preliminary construction on the project began in 2009 and the superstructures were approved in 2011. Pouring of roller-compacted concrete for the dam began in 2012.[3][4][5] The dam began to impound its reservoir in December 2015.[6] Lizhou Dam started producing its power in 2016, when the whole facility was commissioned.[7]
