The dam serves several purposes including irrigation in the Fergana Valley and hydroelectric power production. Water released from the dam can enter a canal on either side of the river downstream. The dam has two power stations located at its base, Andijan 1 and Andijan 2. The former contains four 35 MW turbine-generators and the latter contains two 25 MW Francis turbine-generators for a total installed capacity of 190 MW.
Construction on the dam began in 1969 and the generators at Andijan 1 were commissioned between 1974 and 1984.[1] Construction at Andijan 2 began in 2007 and it was commissioned on 2 September 2010. It cost US$28.5 million of which US$15.93 million was provided by the Exim Bank of China.[2]
The artificial lake created by this dam, the Andijan Reservoir, is fed by the Kara Darya and its tributaries Kurshab and Jazy.[citation needed]
