Executive Committee of National Economic Council (ECNEC) has approved Warsik hydroelectric power station at a rationalised cost of Rs 22.254 billion with an FEC of Rs 11.283 billion. According to sources, power generating capacity of Warsik hydel power station had been reduced from 243 MW to 150 MW with the passage of time due to (i) structural deformation of the power house due to alkali aggregate reactivity and;(ii) rapid erosion in the hydraulic equipment due to abrasive attach of the silt carried out in the Kabul river.
These issues were resolved jointly by the Government of Pakistan and Canada under the rehabilitation program(phase-1) at the cost of Rs 1.325 billion which was completed in 2006. Rehabilitation works under phase-II would address the main problems of th e Warsik site to increase its generation capacity from 193 MW( recorded in 2013) to actual 243 MW by carrying out rehabilitation works in the following main areas: (i) rehabilitation works of civil components such as intake structure of main dam spillway, power house and other structures;(ii) repair and replacement of heavy mechanical systems such as trash rack cleaning and handling mechanism, operating lifting mechanism of spillway gates, draft tube gantry crane etc;(iii) replacement and refurbishment of electrical and production equipment and auxiliary mechanical systems;(iv) rehabilitation, upgradation and modernisation of the existing generating units and auxiliary of Warsak hydroelectric power station to maintain utilisation of low cost hydropower and to provide reliable and consistent power to the national grid for another 40 years life;(v) regarding the installed capacity of 243 MW presently reduced to 193 MW( 50 MW) at very low cost and completion time;(vi) reclaim the unwanted head losses caused by restrictions of the water passage are at the intake structure and build a sediment mitigation infrastructure at the upstream of the existing intake;(vi) replace with new or repair and improve the durability of all submerged components currently affected by erosion and protect these to provide 40 years of additional life and ;(vii) upgrade or replace deteriorated or obsolete mechanical and electrical equipment(like modernisation of balance of point), switchyard and peripheral equipment) and increase energy production and reliability.
The project was considered by the CDWP in its meeting on March 4, 2015 and approved in principle subject to rationalisation of the cost of the project by a committee comprising Member (Energy) , Member (I&M), Chief (Energy ) and the sponsors. The committee held deliberations and rationalised the overall cost of the project from Rs 23.365 billion including an FEC component of Rs 12.181 billion to Rs 22.254 billion. ECNEC has recently endorsed the decision of committee of Planning, Development and Reforms Division.
