Electrical Energy Crises
Remedial Measures,
Emphasizing the hydel
power role
By
Prof.Dr Engr.S.M.Bhutta
 Energy the lifeline of economic development.
 Pakistan is the poorest of the poor as far as
energy consumption for capital is concerned.
 Per capita energy consumption, is one of the
indicator of Industrial development and quality
of life of a country.
 Pakistan has 14 Million BTU’s as compared
to 92 Million BTU’s of Malaysia and 34 Million
BTU’s for China.
 Per Capita electrical consumption per year of
Pakistan is 470kWh, & of Malaysia is 2,708 &
of Singapore is 6,775 kWh

Institutional Barriers.
5.Financial Barriers.
6.Interconnection Barriers.
7.Tariff.
8.Procedural impediments.
9.Risks
a. Hydrological Risks
b. Geological Risks.
c. Environment Risks.
d. Miscellaneous.
Technology and information Barriers.
We lack knowledge & information about the technology
of hydel power.
Need for education of hydel power technology not only
for the students & engineers but also for general public

KALABAGH DAM PROJECT
(Multi Purpose but Made Controversial)
1. NEED FOR KALABAGH DAM FOR IRRIGATION & ELECTRICTY
35 million acres land of Pakistan is irrigated
by canals and tube wells.
Canal with drawl increased from 67 to 105
MAF between the years 1947 and 1976 .
Storage depleted by 5MAF by 2006.
Situation of water shortage, threat of famine
Pakistan will have reached the stage of
“acute water shortage”, where people fight for
every drop of water.
NATIONAL LOSS IF KALABAGH DAM IS NOT BUILT
National food needs would be jeopardized as of population growth.
28% loss of storage capacity of the on-line reservoirs due to sedimentation
would result in shortage of committed irrigation supplies.
For implementation of Water Apportionment Accord 1991, new storages
are essential. In its absence it would give rise in bitter inter-provincial
disputes,
The Annual energy generated at Kalabagh would be equivalent to 20
million barrels of oil otherwise needed to produce thermal power.

APPREHENSION OF NWFP
1. flooding of Peshawar Valley including Nowshera
®Backwater effect of Kalabagh Lake would end about 10 miles
downstream of Nowshera.
2. Area of Mardan, Pabbi and Swabi plains would be
adversely affected creating water logging and salinity.
® Lowest ground levels at Mardan, Pabbi and Swabi areas are
970, 960 and 1000 feet above MSL respectively, as compared to
the maximum conservation level of 915 ft for Kalabagh operation
pattern of reservoir cannot block the land drainage and cause
water logging or salinity
4.Operation of Mardan SCARP would be adversely
affected.
®The invert levels of main drains of Mardan SCARP are higher
than reservoir elevation of 915 feet and the back water level in
Kabul River and Kalapani Khwar. These drains would keep on
functioning without any obstruction.
5.Fertile cultivable land would be submerged.
®Total cultivable affected land under the reservoir is only
35,000 acres,(24,500 acres in Punjab 3,000 acres in
NWFP).irrigated land would be only 3,000 acres (2,900 acres in
Punjab and 100 acres in NWFP).
6.Population Dislocation
® total population to be relocated is 120320 of which 78170
shall be from Punjab and 42150 from NWFP.
Resettlement of Affected Population will be properly
compensated
APPREHENSIONS OF SINDH
No surplus water to fill Kalabagh reservoir
® Annual average of 35 MAF has escaped below Kotri to Sea.
® Kalabagh reservoir will be filled up by only 6MAF, which will
gradually be released to the provinces.
® Indus River System Authority (IRSA) has studied and
confirmed that sufficient water is available for further storage.
2. Anxiety the project would render Sindh into desert.
® Dams don’t consume water! These only store water during
flood season and make it available on crop demand basis
® It estimated that after Kalabagh, the canal withdrawals for
Sindh would further increase by about 2.25 MAF.
3.Outlets would be used to divert water from the reservoir
®The project design does not include any provision for
diverting water from reservoir.
® A telemetric system employing modern electronic technology
has recently been installed at each barrage and other flow
control points to monitor discharge in various canals
commands, on real time basis under the auspices of Indus
Water River System Authority (IRSA).
4.Cultivation in “Sailaba” areas would be effected
® Flood peaks above 300,000 cusecs would still be coming
after construction of Kalabagh Dam, without detriment to the
present agricultural practices, while large floods would be
effectively controlled. This would, in fact, be conducive to
installation of permanent tube wells to provide perennial
irrigation facility in rive rain areas. The local farmer can look
forward to having two crops annually instead of the present
one crop.
5.Sea Water intrusion estuary would accentuate.
® Data shows that sea water intrusion, seems to be at its
maximum even now, and it is unlikely to be aggravated further
by Kalabagh Dam.

Challenges in Hydropower Projects
More Capital intensive compared to thermal
Longer gestation and construction Period
More Construction Risks (inflation, cost overruns, delays, geological
surprises, floods, extreme weather, socio-political)
Higher Tariff in the initial years
No “off-the-shelf” or standard machines similar to thermal plants
Very site specific. Usually a number of options for developing each site
High percentage of civil works (70-75%) - difficult to estimate end costs
Operational Risks (hydrological risk, multiple uses, future
developments/diversions)
Environmental & resettlement issues
Institutional set up at provincial level
42
Challenges in Hydropower Projects
Generally located in remote area, lack of basic
infrastructure (access roads, tunnels, electricity,
telephone, colony, potable water, manpower)
Dedicated and expensive delivery infrastructure required
Extra thermal capacity for backup in low water season
Hydel Generation varies with availability of water & head
Limited International experience in Private Hydropower
Projects
Specific Tariff & Security Documents issues
Project Agreements (IA, PPA) are different and complex
Clearances from the Provinces, Water Use Agreement
etc.
