Pakistan Prime Minister Shehbaz Sharif has ordered an investigation into the power outage that occurred at 7.

The national grid’s frequency fell about 7:34 a.m., causing a “widespread disruption” in the energy system, according to a statement from Pakistan’s Ministry of Energy. It also said that Warsak was the starting point for grid station repairs.

However, electricity has yet to be entirely restored nationally, impeding businesses and the everyday lives of more than 220 million people.

According to Geo TV, the blackout lasted more than 16 hours, especially because temperatures were expected to drop to roughly 4 degrees Celsius (39°F) in Islamabad and 8 degrees Celsius (46°F) in Karachi.

The blackout, which Energy Minister Khurram Dastagir blamed on a power spike, is the second big system failure in three months and adds to Pakistan’s practically daily outages.

According to AAJ News, the power outage happened when a technical failure was discovered in the transmission line from Guddu to Quetta, causing the power frequency to be reduced from the optimal level.

According to sources, the power outage affected the Sindh, Punjab, and Islamabad areas. According to reports, the entire restoration of electricity can take time. It is the second power outage recorded in Pakistan in the last four months, which is now coping with an energy crisis and rising energy bills.

According to a news source, Islamabad Energy Delivery Company (IESCO), which distributes electricity to Islamabad, Rawalpindi, Attock, Jhelum, Chakwal, and sections of Pakistan-occupied Kashmir (PoK), has discontinued power supply to 117 grid stations.

“Power supply to 117 grid stations of ISCO has been interrupted, although no clear cause has been supplied by the Region Control Center,” IESCO tweeted. ISCO management is in close contact with the appropriate authorities.
