The power outage that affected the majority of the nation on January 23 has been the subject of a preliminary investigation by the National Transmission and Despatch Company (NTDC).
The blackout, according to the report, was brought on by a frequency fluctuation that started on Monday morning in Guddu. 500KV wires from Guddu were consequently tripped.
Before the breakdown, Guddu’s frequency was 50MHz. The transmission cables tripped as a result of the abrupt increase to 57MHz. As a result, transmission lines at Tarbela, Mangla, and Warsak were also disrupted.
Most of the nation witnessed an hour-long electrical outage around 7:34 AM, including Islamabad, Karachi, Lahore, Quetta, and other significant cities.
Teams from NTDC sprang into action right away to restore the power. It took them a number of hours to find a solution. In the majority of the country, electricity had been restored by Monday night.
Federal Energy Minister Khurram Dastgir Khan speculated that the malfunction may have been caused by a cyberattack during a press briefing on January 24, Tuesday. He stated that although it was unlikely that hackers were involved, NTDC will look into it just in case.
