Yalong River Hydropower Development Company, Ltd. (Yalong Hydro) is a fully state-owned hydropower developer/owner based in Chengdu, China. 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.

Incorporated in 1989, Yalong Hydro started with the Ertan Hydroelectric Project. 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. Of these stations, Jinping-I has the world’s tallest double-curvature arch dam of 305m in height.

Another two hydropower projects, Lianghekou and Yangfanggou, are under construction and will increase the company’s generation capacity by another 4,500 MW when completed in early 2020s. Hydropower development of the entire river is expected to be accomplished in the next 20 to 30 years.
