The Jinping-II Dam (simplified Chinese: 锦屏二级水电站; traditional Chinese: 錦屏二級水電站; pinyin: Jǐnpíng Èrjí Shuǐdiàn Zhàn), also known as the Jinping-II Hydropower Station, is a gravity dam on the Jinping Bend of the Yalong River (Yalong Jiang) in Sichuan, China.

While Jinping-I relies on a conventional tall dam and large reservoir to supply water, Jinping-II uses a much smaller dam, located 7.5 km downstream of Jinping-I, to divert water into four 16.6 km long headrace tunnels.

These tunnels connect to a downstream point on the same river at a much lower elevation, providing a 310 m (1,020 ft) head of water[1] without flooding a large area of land.

Planning for the projects began in the 1960s under the former Sichuan and Shanghai design institutes along with the Ministry of Water Resources and Electric Power.

About 30% of the power from the Jinping dams is used locally, and 70% will be sent to eastern China via ±800 kV bipolar HVDC transmission lines.
