JINNAH HYDRO POWER PROJECT
February, 2010February, 2010
HISTORY
• The joint agreement between government of Pakistan through WAPDA and federal republic of Germany was carried out on 13th Oct 1982 to implement the Programme for development of hydro power at barrages and Canal falls in the Indus plains.
HISTORY Continue……..• After extensive study 10 sites were
selected and Jinnah scheme was ranked as the 3rd under barrages.
• The feasibility study was started in Feb 1988 by Binnie and partners in association with ODA (overseas Development Administration),UK. and submitted to WAPDA on Jan 31st 1988.
HISTORY Continue……..
• The study envisaged construction of a project having installed capacity of 96 MW with 8 units & the design head of 4.7 meters with discharge rate 350 m3/s for each unit and energy out put of 688 GWH per annum on the basis of revised sediment model studies conducted at irrigation institute Nandipur.
LOCATION• Jinnah Hydro Power Project is proposed
on the right side of existing Jinnah Barrage as a by pass arrangement.
• It is located on the Indus River about 5 KM D/S of the town of Kalabagh in the District of Mianwali and 234 Km away from Islamabad.

WHAT DOES LOW HEAD HYDEL MEANS?
• Lowland Plants
• Low Head Plants
• Hilly Area Plants
• Medium Head Plants
• Mountainous Region Plants
• High Head Plants
• Low head potential in Pakistan means, the potential available at barrages and canal falls in the plains of Punjab, Sind, NWFP and Baluchistan

PROJECT LAY-OUT• Head Race Channel
• Tail Race Channel
• Power House
• Switch Yard
• The head race will off-take from right guide bank about 1300 m u/s of Jinnah Barrage.
• It has curved alignment of 500 m. • It becomes straight for about 800 m u/s of
Jinnah Barrage.
Head Race Channel
• The maximum pond level is 211.50 m.a.s.l and top level of embankment has been fixed at 215.00 m.a.s.l.
• The side slopes of the power channel are 1:3 and the bed level for the head race channel is fixed at 202.50 m.a.s.l.
Head Race Channel continue…
• The tail race having the length of 500 m will join the power house out flows to Indus River.
• The maximum design discharge of the power channel is 2800 Cumecs.
Tail Race Channel
Power House
• The Power house consist of 4 Turbine blocks and 1 service bay. Each turbine block consists of 2 units and service bay is provided on the left side the power house.
• It will be equipped with 8 pit type turbine having its speed 60 rpm.
Pit Type Turbine• For heads lower than 10 m, pit-type
turbines have been applied, with a speed increaser located between the runner and generator.
• Since 1955 over 180 machines have been put into operation all over the world with outputs from 50 kW to nearly 50,000 kW and diameter between 800 mm and 8400 mm.
Trend of Generator Output
Switchyard• An open 132 Kv
switchyard will be constructed on the right side of the power house and will be connected to 132/220 Kv Mari Daud Khel Grid station about 4 KM from the project through 132 Kv overhead transmission line.
PROJECT BENENITS
• Reduction of dependence on thermal power.
• Saving in foreign exchange.
• Employment opportunity during construction and operation.
• Improved standard of living and infrastructure.
• Socio-economic uplift of the area.
ENVIRONMENTAL & SOCIAL IMPACT
• Initial environmental examination shows no major impact except effect on fish migration in case the whole flow is diverted.
• There will be no significant effect on fish population / production.
• The project lies in dry arid climate area of kalabagh in mianwali.
ENVIRONMENTAL & SOCIAL IMPACT
continue….• There will be no loss of forest and wild life.• There will be no any effect on the cultural
and heritage.• Sociological impacts will be balanced by
the project benefit in terms of improved employment, infrastructure and standard of living.
