The Nurek HydropowerScheme is located 80 km (by road) from Dushanbe, the capital of Tajikistan, in the Danghara and Nurek districts of SouthernTajikistan, on the Vakhsh River.

The initial installed capacity of the power plant was 2,700 MW and was then increasedto 3,000 MW in 1988 through an upgrade of the hydraulic turbines.

In recent years, the maximal capacity of the plant can be saidnot being higher than 2,320 MW.
