Darunta Dam was constructed by Soviet Union (USSR) companies in 1964[1] and its power station contains three vertical Kaplan turbines (six-blade propeller) with a rated output of 3.85 MW each. Originally, the dam supplied 40 to 45 megawatts of electrical power[2] but silting and damage to the system during the Afghan civil war has reduced its actual output to 11.5 megawatts.
