Nuozhadu Dam is an embankment dam on the
Lancang (Mekong) River in
Yunnan Province, southwest China. The dam will be 261.5 m (858 ft) tall, and will create a reservoir with a normal capacity of 21,749,000,000 m
3 (17,632,000 acre·ft) at a level of 812 m (2,664 ft) asl. The purpose of the dam is
conventional hydroelectric power production along with flood control and navigation. The
Nuozhadu Dam will support a power station with nine generators, each with generating capacity of 650 MW. The total generating capacity of the project is 5,850 MW.
The construction and management of the project is being implemented by Huaneng Power International Ltd., which has a concession to build, own and operate
hydroelectric dams on China's stretch of the Mekong River.
