Nuozhadu Dam (simplified Chinese: 糯扎渡大坝; traditional Chinese: 糯扎渡大壩; pinyin: Nuòzhādù Dàbà) is an embankment dam on the Lancang (Mekong) River in Yunnan Province, southwest China. The dam is 261.5 m (858 ft) tall, and creates a reservoir with a normal capacity of 21,749,000,000 m3 (17,632,000 acre·ft) at a level of 812 m (2,664 ft) asl. The purpose of the dam is hydroelectric power production along with flood control and navigation. The dam supports a power station with nine generators, each with generating capacity of 650 MW. The total generating capacity of the power station is 5,850 MW.[2] Construction on the project began in 2004; the dam's first generator went online 6 September 2012 and the last generator was commissioned in June 2014.[3][4] The construction and management of the project was 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.
