The Nurek Dam (Tajik: Нерӯгоҳи обии Норак, Nerūgohi obii Norak, Tajiki for Nurek Hydro-electric Station) is an earth-fill embankment dam on the Vakhsh River in the central Asian nation of Tajikistan. Its primary purpose is hydroelectric power generation and its power station has an installed capacity of 3,015 MW. Construction of the dam began in 1961 and the power station's first generator was commissioned in 1972. The last generator was commissioned in 1979 and the entire project was completed in 1980 when Tajikistan was still a republic within the Soviet Union. At Script error: No such module "convert".,[1][2][3] it is currently the second tallest man-made dam in the world. The Rogun Dam, also along the Vakhsh in Tajikistan, may exceed it in size when completed.


The Nurek Dam was constructed by the Soviet Union between the years of 1961 and 1980. It is uniquely constructed, with a central core of cement forming an impermeable barrier within a Script error: No such module "convert".-high rock and earth fill construction.[1][2][3] The volume of the mound is 54 million m³. The dam includes nine hydroelectric generating units, the first commissioned in 1972 and the last in 1979.[2]

The dam is located in a deep gorge along the Vakhsh River in western Tajikistan, about Script error: No such module "convert". east of the nation's capital of Dushanbe. A town near the dam, also called Nurek, houses engineers and other workers employed at the dam's power plant.

Electricity generation

A total of nine Francis turbine-generators are installed in the Nurek Dam's power station. Originally having a generating capacity of 300 MW each (2,700 MW total), they were redesigned and retrofitted between 1984 and 1988 so now have a capacity of 335 MW each (3,015 MW total).[2] As of 1994, this formed most of the nation's 4.0 gigawatt hydroelectric generating capacity, which was adequate to meet 98% of the nation's electricity needs.[4]

Nurek reservoir

The reservoir formed by the Nurek Dam, known simply as Nurek, is the largest reservoir in Tajikistan with a capacity of 10.5 km³. The reservoir is over Script error: No such module "convert". in length, and has a surface area of Script error: No such module "convert".. The reservoir fuels the hydroelectric plant located within the dam, and stored water is also used for irrigation of local agricultural land. Irrigation water is transported 14 kilometers through the Dangara irrigation tunnel and is used to irrigate about Script error: No such module "convert". of farmland. It is suspected that the reservoir may have caused induced seismicity when being impounded.[1]
