Abstract

In 1978, the Jinping Project was designed as an integrated hydroelectric power scheme on the Yalong River in Southwest China. Jinping I involves a 305 m high arch dam on the upstream side of the Great Jinping River Bend. Water is directed through the mountains in four 16.7 km long, c. 13 m diameter tunnels, beneath up to 2,525 m of overburden, to the Jinping II underground powerhouse where the head is 310 m. The combined schemes will produce 8,400 MW and an annual power generation of 40.8 TW.h.
