The largest power plant of Pakistan, Guddu thermal power house, tripped on Sunday due to dense fog, affecting huge swathes of the country.
The provision of electricity was suspended to interior Sindh, Balochistan and other areas of the country as a result of the malfunction.
All the power producing units were shut down; however, efforts are being made to restore unit no 3.
Currently, 650 megawatt electricity is being provided to the national grid through Guddu power house.
It is one of the oldest power plants in the country, and has three large transmission lines that feed its output to Punjab, Sindh and Balochistan.
