The Ahai Dam is a dam under construction with a rolled concrete (RCC) gravity dam on the Jinsha Jiang (Chinese name for the upper reaches of the Yangtze River ) in Yulong County , Lijiang Prefecture , Yunnan Province in the People's Republic of China . It is about 5 km from the mouth of the Cuiyu.

The hydropower plant will be equipped with five Francis turbines with a nominal output of 400 MW each, which corresponds to a total output of 2000 MW. This means that an estimated 8.887 billion kilowatt hours of electricity can be generated annually .

Damming of the reservoir began in December 2011 and the first generator is scheduled to go into operation in 2012 . The construction costs are 13.6 billion renminbi or 2 billion US dollars.
