Reasons
Late finalization of 2002 power policy
Late initiation of new projects
Long processing time
Not soliciting new power plants
Reliance of unsolicited proposal
WAPDA was not allowed to install thermal power plants
Private sector started taking advantages
Availability of machines in the international market
Reasons (contd)
No serious efforts on effeciency improvement and energy conservation
Time of day metering system is not up to its strength
Hydropower not comming up
Small hydro power plants are not being taken up by WAPDA
Closure of some IPP & WAPDA‘s power plants
Not payment of fuel bills to fuel suppliers
Reasons (contd)
International investors are not comming with enthusiasm International recession
Governace issue
No serious efforts to exploit alternative energy resources
Huge reserve of coal is not being used
Issues
Most of the new thermal power plants are based on fuel oil
Cost of electricity generations
Fuel imports – major implecations on forx reseve
Volatility of crude oil prices
Fuel transporation and import infrastructure
Road / railway network
Port facilities
Issues (contd)
Gas is not available for new power plants
Un efficient energy useage
No incentive from the government to develop alternative energy resources
Rental power plant is sucidal
Remedies / Suggestions
Development of alternative energy
The Regulator should be linient in tariff for wind and solar power plants
Manufacturing facility for wind and solar power plants be encouraged by the government
Coal should be used for power generation including imported Coal
Thermal power plants should be installed by WAPDA in parllel to IPPs
More emphasis should be on energy conservation and efficiency improvement
Remedies / Suggestions (contd)
Time of day tariff should be implemented in all catagories of consumers
A digonostic study should be conducted for oil transporatation infrastructure and port facilities
Captive power plant should brougt on bar
Industrial sector should be encouraged to install their own power plants and surplus should be purchased by WAPDA at a competitive price
