ISLAMABAD : The electricity shortfall has peaked to 3,200 megawatts, causing 7-hourly load shedding even on holiday(s) in major cities, while rural areas suffer for an 11-hour spell. A private TV channel reports that overall demand of electricity stood at 13,000 MWs against way out lesser 9800MW production figure, by all three production sources. Hydel sources are contributing 3,000 MWs through windmills due to water shortage, Thermal plants generating 1615 MWs and Independent Power Producers (IPPs) restricted at 5085 MWs, all of which was encouraging increase in load shedding durations.
