“Power at all 1,112 stations of the national grid has been restored,” Dastgir tweeted as quoted by Dawn News.

“But with the support of the Power Division, Wapda and other departments, we fixed the technical problem after which power at systems across the country was restored.

“Today, at 5:15am, the system was completely restored across the country,” Dastgir said.

He said there will be a shortage of power in the next two days.
