Jinping-II Dam

The Jinping-II Dam (simplified, traditional, 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. Construction on the project began in 2007 and it was complete in 2014. Its hydroelectric power station has a 4,800 MW installed capacity. 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 without flooding a large area of land.
