KARACHI, Aug 13: Under-frequency in the national grid on Tuesday put many KESC grid stations out of action for some time, forcing the utility to resort to loadshedding.

This problem resulted in a shortfall of 60-101mw for most of the day, which between 7:30pm to 8pm touched 261mw. After 8pm the shortfall reduced to 101mw.

After the problem in the national grid, the KESC was resorting to one-hour loadshedding on a rotation basis in four groups.

A KESC spokesman hoped that the situation would normalize during the night as efforts were on to rectify the fault.

The KESC consumers have been suffering due to neglect of proper maintenance and upgradation of the system both by the KESC and Wapda.

While the two utilities occasionally trade accusation and blame each other for the failures, industry and the general public suffer and make the need for another KESC-owned generation plant.
