After the construction of the dam for it to be formed Rogun reservoir full volume of 13.3 cubic km It is planned to use both energy and irrigation purposes, reports “Interfax”. According to the schedule the first unit of the Rogun hydropower plant will earn at the end of 2018 and the second in April 2019.

Preparations for the construction of HPP was started in 1976. The first floor of Vakhsh was celebrated on 27 December 1987. By 1993 th height of the cofferdam had reached 40 m, was built 21 kilometers of tunnels. After the collapse of the Soviet Union due to the lack of necessary means Tajikistan hydroelectric power station was mothballed. 8 may 1993 horse construction the cofferdam was washed out a powerful flood flow, the tunnel and the engine room was partially flooded.
The government of Tajikistan envisages construction of the Rogun hydropower plant achieving energy security of the country and the possibility of replenishment of the budget through the sale of electricity abroad. The new facility also will allow to avoid the blackouts, which sometimes cover almost the whole country.
Now three of the four first lines in the list of the high dams is the creation of the Chinese engineers. In second place in the list is a 300-metre Nurek dam, which covers three quarters of Tajikistan’s needs in electricity. The rest of the country imports from Uzbekistan and Kyrgyzstan.
