The primary purpose of the dam is hydroelectric power generation and it supports three power stations downstream, the Renzonghai, Jinwo and Dafa Hydropower Stations. Water from the dam is sent via penstock first to the 246 MW Renzonghai (29°23′52.38″N 101°58′34.41″E / 29.3978833°N 101.9762250°E) then the 287.2 MW Jinwo (29°23′13.74″N 102°3′44.43″E / 29.3871500°N 102.0623417°E) and finally, the 246 MW Dafa Hydropower Station (29°23′31.79″N 102°5′15.36″E / 29.3921639°N 102.0876000°E). The total installed capacity of the power stations is 779.2 MW Construction on the project began in August 2004 and the Jinwo power station was commissioned
