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 300 m (980 ft)-high rock and earth fill construction. 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.
The dam is located in a deep gorge along the Vakhsh River in western Tajikistan, about 75 km (47 mi) 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.A total of nine hydroelectric Francis turbines are installed in the Nurek Dam. Originally having a generating capacity of 300 megawatts each (2.7 gigawatts total), they have since been redesigned and retrofitted such that they now combine to produce 3.0 gigawatts. 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.
