Infrastructure

With the time DVC developed and expanded its infrastructure Five thermal power

stations with a capacity of 2570 MW, three hydro-electric power stations with acapacity of 144 MW and one gas turbine station with a capacity of 82.5 MW

contribute to a total installed capacity of 2796.5 MW. Presently DVC has 60 sub-stations and receiving stations more than 5500-circuit km of transmission and

distribution lines. DVC has also four dams, a barrage and a network of canals that

play an effective role in water management. The construction of check dams,development of forests and farms and upland and wasteland treatment developed by

DVC play a vital role in eco conservation.
