No incentive from the government to develop

alternative energy resourcesRental power plant is sucidal

7/30/2019 Presentation to IEE

Remedies / Suggestions

Development of alternative energy

The Regulator should be linient in tariff for wind andsolar power plants

Manufacturing facility for wind and solar power plantsbe encouraged by the government

Coal should be used for power generation includingimported Coal

Thermal power plants should be installed by WAPDA inparllel to IPPs

More emphasis should be on energy conservation andefficiency improvement

7/30/2019 Presentation to IEE

http://slidepdf.com/reader/full/presentation-to-iee 16/17

Remedies / Suggestions(contd)

Time of day tariff should be implemented in allcatagories of consumers

A digonostic study should be conducted for oil

transporatation infrastructure and portfacilities

Captive power plant should brougt on bar

Industrial sector should be encouraged toinstall their own power plants and surplusshould be purchased by WAPDA at acompetitive price
