Almost 40 percent of Karachi has plunged into darkness when a high tension (HT) transmission line tripped, causing several grid stations to trip, reports ARY News.

The power breakdown hit several neighbourhoods of the city, including Numaish Chowrangi, Saddar, Lines Area, Defence Housing Authority (DHA), Punjab Colony, Gulistan-e-Jauhar, Korangi, among others.

K-Electric, the utility company responsible for electricity supply in the metropolis, did not issue a formal statement on the matter.

“This has also cascaded to KE’s network affecting power supply to Karachi,” Rana said, adding the KE’s network is safe and protected.

He said the company is currently monitoring the situation and attempting to restore the electricity.
