KARACHI: With Karachi being the worst hit city, parts of Pakistan including Sindh, Balochistan, Khyber Pakhtunkhwa, and some areas of Punjab are out of power after a major technical fault crippled the national grid here on Tuesday night, Samaa reported.
“A 220 KV transmission line malfunctioned after a conductor on a power pylon broke down. As a result result Bin Qasim Power Plants tripped offline ” a spokesman for K-Electric, Karachi's main power utility, told Samaa.
The spokesperson also clarified that K-Electric was not responsible for the breakdown.
“We have reports that a huge part of the metropolis is facing a blackout,” Qureshi added.
According to the power company mouthpiece, engineers were racing against time to fix the breakdown.
“From Kalat to Karachi, most of the major cities have reported sweeping power failure,” sources told Samaa.
In Karachi, dozens of grid stations tripped offline, leaving at least 90 per cent of the city submerged in darkness. Similar reports were pouring in from other parts of Sindh by the time of filing this report.
The electricity supply to most of Balochistan including areas like Kalat, Sorab, Mangochar etc, while in tKhyber Pakhtunkhwa, the provincial capital Peshawar, Hazara Division, Mansehra, Abbottabad, Oggi, Batgaram are plunged in the darkness.
Peshawar Electric Supply Company (PESCO) says they crews are out in the field trying to sort the problem out.
Expert say this chain reaction or somewhat domino effect of 'power failure' was actually set into motion after Bin Qasim units tripped offline.
“It was not the first time that both the plants had gone down triggering a near nationwide power collapse,” they added.
According to sources, a full restoration of electricity supply may take more than two hours.
Tripping or power-system protection is aimed at protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network.
The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation.
