Authorised by the Chinese government, Yalong Hydro is solely responsible for development and operation of the planned 22 cascade stations on the river of Yalong with a total installed capacity of 30 GW.

With a double-curvature concrete arch dam of 240m in height and an installed capacity of 3,300 MW, it used to be China’s largest hydropower project. Yalong Hydro currently has five large hydropower stations in operation, totalling 14.7 GW in capacity and producing approximately 70 TWh of electricity per year on average.
