ISLAMABAD: Most areas of Islamabad, Punjab, Khyber Pakhtunkhwa and Azad Kashmir remained deprived of power supply for consecutive five to nine hours owing to certain major technical glitch in National Power Control Center.
The power grid experienced an unusual breakdown after Tarbela and Ghazi Barotha powerhouses ground to a halt due to certain technical fault.
Meantime, Prime Minister Nawaz Sharif took notice of topsy-turvy power system that left half of the country devoid of electricity for consecutive five to nine hours. He summoned a report from the Water and Power Ministry over the issue.
A technical fault that appeared at around 1pm caused the power lines from Tarbela and Mangla power plants to simultaneously trip off. The tripping of the main transmission lines left the national grid shorn of 5000 megawatts that cut off the power supply to the 80 percent areas of Punjab including Islamabad, Rawalpindi, Lahore and Faisalabad.
The power supply to the affected areas was restored in phases after 6pm. The restoration process was completed by 10pm, when all domestic feeders were put back on track.
According to the Water and Power Ministry, the technical flaw could not be traced as yet. The protracted power breakdown left the business of life across half of the country in the lurch.
Cities including Mardan, Swabi, Nowshera, Haripur, Attock, Lahore, Gujranwala, Sialkot, Gujrat, Faisalabad, Chakwal, Jehlum suffered owing to unusually prolonged breakdown today.
