A blackout is being observed in Lahore, Multan, Bahawalpur, Gujranwala and other cities in Punjab, and Peshawar, Swat, Lakki Marwat in KP.
Power Division Secretary and other officials are said to have visited the National Power Control Centre to review the situation. The fault at the Tarbela also caused tripping of all four Chashma Power Plants. He said Ghazi Barotha, Tarbela, Mangla had been synchronized and connected to the nation grid system.
Speaking to Geo News, Leghari said that power supply was being restored in majority of areas in Khyber Pakhtunkhwa and Punjab.
The breakdown occurred due to tripping of Muzaffargarh-Guddu main transmission line. However, it will take two to three hours to fully restore the power system. Several operations were postponed, while medics were forced to conduct check-ups in Out Patient Departments (OPDs) in the dark.
"But fix work was started soon after the incident and power was being slowly restored to the affected areas", he said.

A spokesperson of the Atomic Energy Commission informed that industrial load-shedding amounting to ten hours would also begin in Punjab today.
Reacting to the move, the All Pakistan Textile Mills Association vowed to protest, saying only Punjab's industries were being denied power for 10 hours a day.
Leghari promised a probe into the causes of the breakdown, which has caused huge embarrassment for the government ahead of the election expected to be held in July.
The association has issued a statement that it will meet the finance minister first regarding this announcement of the Power Division.
