Last month, the port city suffered three major outages in four day due to a major fault that developed in the K-Electric’s distribution system.

KE had said the disruption in power supply was triggered by a rollover effect following the disconnection of Karachi’s power supply lines from the national grid.

The spokesperson of National Transmission and Dispatch Company (NTDC) in his statement said that the Southern region from where power is supplied from the national grid tripped due to dense fog, Express News reported.

K-Electric's own system also tripped, suspending power supply in Karachi. "The NTDC's entire system is however, operating in the rest of the country."
