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

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
