5. INTRODUCTION
 Warsak Power Station is a monument of the
friendship of Canada and Pakistan.
 Warsak Power Station was built in two phases
as co-operative effort between the two
Governments.
 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. The total installed capacity thus amounted
to 242.96 MW. With time the power generating
capacity was reduced to 150 MW.

6. Location
 The gigantic multi-
purpose “Warsak
Dam” on River
Kabul situated 30
KMs North-west of
Peshawar in the
heart of tribal
territory .

7. History
 Warsak Hydroelectric Power Project was
completed under Colombo Plan in two phases,
financed by Canadian Government.
 The first phase was completed in 1960 at a
total cost of Rs.394.98 million, consisting of
construction of Dam, Irrigation tunnels, civil
works four Generating Unit for capacity of 40
MW each and 132 K.V transmission system.
 In 2nd Phase, Two additional generating units
each of 41.48 MW were added in 1980-81 at a
cost of Rs.106.25 Million

10. Components of Dam
 The Warsak dam is a concrete, straight gravity type bulkhead.
It is 460 feet high. Below the dam, a concrete stilling basin is
provided to absorb and dissipate the energy of the falling
floodwaters.
 The powerhouse is located on the surface, on the right bank
below the downstream face of the dam. A 35 feet internal
diameter tunnel, which is 1,800 feet long with a maximum
discharging capacity of 32,500 cusecs, is located along the left
bank of the river extending from upstream to downstream face
of cofferdam. Two cableway benches for concrete bucketing for
the dam and stilling basin are also provided along the hill-
slopes. The intake structure and power tunnel, having an
internal diameter of 39 feet, are located on the right bank.
There are 6 underground penstocks with 18 feet diameters for
the 6 generators. A 3.5 miles long, 10 feet diameter concrete
lined irrigation tunnel is located on the right bank to irrigate
120,000 acres of land.

14. Capacity
 The total installed capacity of the “Warsak
Dam” Hydropower Project is 243 MW. In
June 2012, the Pakistan WAPDA (Water
and Power Development Authority) decided
to add a 375 MW powerhouse to Warsak,
which will raise Warsak's total power
generation capacity to 525 MW.
 No date was given on when the project
would be complete…

15. Importance of project
Warsak is so located that it
has to play an important role
in establishing voltage in
Peshawar and further in
Kohan, Parachinar, and
Bannu. As such, its fullest
capacity has to be restored.

16. First Rehabilitation Project (1996-2006)
 Phase-I Rehabilitation was carried out due to
two major reasons, firstly Structural deformation
due to Alkali Aggregate Reaction (AAR) and
secondly, severe erosion of the hydraulic
equipment due to abrasive nature of silt carried
in the Kabul River. Governments of Pakistan
and Canada jointly carried out the
Rehabilitation Project under CIDA Grant of CD
27 million during 1996~2006. As a result of the
rehabilitation works completed in this phase,
the Civil Structures became stable, besides, the
reduced capacity of Power Station increased
from 150 MW to about 220 MW.

17. Second Rehabilitation Project (Planned)
 The aging problems of E&M equipment aggravated
further with the passage of time, resulting in consequently
the generating capacity reduced to 193 MW and reliability
of the station also reduced. Second (2nd) Rehabilitation of
Warsak Hydroelectric Power was planned with the
objective to overcome the aging problems, regain the
capacity loss of 50 MW with reliable annual energy
generation of 1,144 GWh, upgrade and modernize the old
system and achieve another life cycle of 30 to 40 years.
Feasibility Study was carried out in 2013 by engaging the
Consultants RSWI-DCE JV. Based on the most viable
option detailed design and tender documents have also
been prepared by the same Consultants. Cost Benefit
Ratio and EIRRare3.65 and 26.9% respectively.
