The Jinping-II Hydroelectric Plant or Jinping 2 Dam, is a large run of the river hydroelectic project on the "Jinping Bend" of the Yalong River (Yalong Jjiang) in Sichuan, China. Construction on the project began in 2007 and when complete, it will have a 4800 MW capacity. While the Jinping 1 will rely on its large dam and reservoir to supply water, the Jinping 2 will rely on four 16.6 km long headrace tunnels that are supplied with water which is diverted by a much smaller dam, which located 7.5 km downstream of Jinping-I dam.

A 37 m tall, 162 m long sluice dam on the west-side of the Jinping bend will divert water into a 16.6 km long headrace tunnel towards the Jinging 2 Power Station. At the power station, the water will spin eight 550 MW Francis turbines with a total capacity of 4400 MW before being discharged back into the river. The dam will be made of 3.4 million m3 of material.
