Warsak Power Station is a monument of the friendship of Canada and Pakistan. This Hydroelectric Project is located on River Kabul at about 30 KM from Peshawar in District Peshawar (KPK). Warask Hydroelectric Power Project was completed under Colombo Plan in two phases, financed by Canadian Government. Construction of 1st phase started in 1951 and in 1960-61, four generating units of 40 MW capacity each were commissioned. The 2nd phase began in 1975 and two more 41.48 MW units were commissioned respectively in 1980-81 at a cost of Rs.106.25 Million. The total installed capacity thus amounted to 242.96 MW. With time the power generating capacity was reduced to 150 MW.
In general the project consists of a mass concrete gravity dam with integral spillway, power tunnel, power station, a concrete lined 10 feet diameter Irrigation on right bank and a 3 feet diameter steel pipe irrigation conduit on the left bank of the reservoir. The 250 feet high and 460 feet long dam with reservoir of 4 square miles as a live storage capacity of 25,300-acre feet of water for irrigation of 119,000 acres of land and meeting power generation requirement. A spillway with 9 gates is capable to discharge 540,000 cosecs of flood. The project is playing a vital role in the development of the country by providing cheap power to the National Grid. The Project has delivered 38629.512 million units to the power system unto August 2011 since commissioning.
