KARACHI: The Power Division of the Ministry of Energy sought reports from the National Transmission and Dispatch Company (NTDC) and K-Electric, after yet another major power breakdown plunged the metropolis into darkness early Monday.
NTDC has been instructed to submit a report on the matter within 24 hours, Geo News reported.
Most parts of Karachi were hit by a breakdown in the early hours of Monday morning, after a transmission line of the national grid tripped.
"Partial supply from national grid has resumed and restoration of power supply to affected areas is progressing swiftly. Supply to parts of Korangi, Garden, Jacob Line, Shah Faisal Colony, Gulshan, Defence, Gizri and Landhi has started," K-Electric, the city's sole power supplier, said in a tweet around four hours after the tripping.
"Full restoration is expected to be achieved over the next few hours," it added.
A "500 kV transmission line connecting KE to the national grid tripped", which "has had a rollover effect on Karachi's electric supply due to which various parts of the city are experiencing an outage," the power utility said.
Areas affected by the power breakdown included Clifton, Gulistan-e-Johar, North Nazimabad, Jahangir Road, FB Area, Malir, PECHS, Garden, Buffer Zone, Nazimabad and Gulshan-e-Hadeed among others.
Schoolchildren and those headed to work faced difficulties owing to the outage.
Last month, Karachi was hit by five major power breakdowns in the span of 25 days.
The National Electric Power Regulatory Authority (NEPRA) had taken notice of the power outages, and in a press release, had stated that K-Electric was not investing to improve its transmission and distribution network.
