LAHORE: A major power breakdown caused due to the tripping of 500 kilo volt (kV) and 220kV transmission lines hit major cities of Punjab on Monday.

The breakdown originated from Islamabad at about 11am after the Rawat 500kV/220kV double circuit transmission lines tripped owing to overloading, leading to a shutdown of operations of the 500kV grid station resulting in power supply suspension to the federal capital, Rawalpindi and adjoining districts, including Jhelum.

Rawat’s cascading effect travelled to the major 500kV/220kV double circuit Ghakhar transmission lines and grid station that shut all 60 132kV grid stations in Gujranwala, Sialkot, Gujrat, Kamoki, Sadhoki, Hafizabad, Mandi Bahauddin and Narowal.
