A major power breakdown plunged parts of the country into darkness late on Saturday night. 

The entire country suffered the blackout as the power generation, transmission and distribution system collapsed.

Lahore, Islamabad, Karachi, Quetta, Peshawar and other parts of the country have been witnessed the outages because of a major fault in the National Power Control Centre (NPCC) system.

Sources said that the breakdown occurred when the Tarbela and Mangla power plants tripped, apparently due to dense fog.

In Karachi, Lahore at least 80 per cent of the city into darkness. Other cities and towns in Sindh also reported complete power outage.

Federal Minister for Power, Petroleum & Natural Resources Omar Ayub Khan said that frequency in transmission system dropped from 50 to zero suddenly which led to power breakdown across the country. He said that the concerned staff were working to restore the power supply in the country. He said that the engineering teams were trying to restore power supply from Tarbela power plant. He said that he was supervising the restoration work.
