The
Jinping-I Dam (simplified Chinese: 锦屏一级水电站; traditional Chinese: 錦屏一級水電站) also known as the
Jinping-I Hydropower Station or
Jinping 1st Cascade, is a tall
arch dam on the "Jinping Bend" of the
Yalong River (Yalong Jiang) in
Liangshan,
Sichuan,
China. Construction on the project began in 2005 and was completed in 2014. Its power station has a 3,600 MW capacity to produce between 16 and 18
TW·h (billion kW·h) annually. Supplying the
power station is a
reservoir created by the 305-meter-tall
arch dam, the tallest in the world. The project's objective is to supply energy for expanding industrialization and
urbanization, improve
flood protection, and prevent
erosion.
