The project consists of the construction of a 335-metre-high clay core rockfill dam, the tallest in the world, on the Vakhsh River. The dam will be located in Rogun, a District of Republican Subordination, one of Central Asia's main mountain ranges.

The agreement between Webuild and OJSC “Rogun Hydropower Project” (the state-run company that is coordinating the project) concerns the exploitation of the Rogun’s huge hydroelectric potential and includes four lots. 

The first lots foresee the diversion of the Vakhsh River that will be done with confluence of two diversion tunnels in a mountainside in order to keep the foundations of the dam dry. It is a very complex task that, because of the strength of the river, will only be able to be done during the winter months when the mountains are covered in snow and the water level is lower. 
Once completed, the plant will have 6 turbines of 600 MW each with a total installed capacity of 3,600 MW (the equivalent of three nuclear power plants).

The most significant impact of the new dam will be to make Tajikistan a point of reference for the energy sector in the region, doubling energy production in the country and strongly contributing to the reduction of power shortages suffered during the winter months.
