Breaking news: TCN restores national power grip collapse after system disturbance

By Ogaga Ariemu

The Transmission Company of Nigeria (TCN), has restored national power grid collapse after system disturbance on Wednesday.

This was contained in a statement released to Nigerian NewsDirect Newspaper on Thursday by TCN’s General Manager Public Affairs, Mrs Ndidi Mbah.

“Transmission Company of Nigeria(TCN) wishes to inform the general public that the national grid experienced system disturbance at about 11.27am today, 20th, July 2022. The incident was a result of sudden drop in system frequency from 49.94Hz to 47.36Hz, which created system instability.

“According to reports obtained from the National Control Centre (NCC), it was precipitated by the tripping of a Unit (with a load of 106 MW) in one of the generating stations due to “Exhaust over Temperature”. This unwholesome event, which pulled out other grid-connected Units in the plant, resulted in aggregated generation loss of 457MW. In its wake, a train of events ensued – culminating in the collapse of the national grid.

“As obtainable in all systems, when a component of the electric power system is defective, the entire configuration is vitiated. However, inspite of setbacks encountered at the initial stage, grid restoration had almost been completed as at 11:00pm when this report was filed.

“The Nigerian Electricity Supply Industry appreciates the kind understanding of the Government and consumers of electricity within and outside the country.

“We are committed to leveraging the concerted interventions instituted thus far to enhance power supply reliability so that the issue of system collapse will soon become a thing of the past. Meanwhile, a full-scale investigation is being conducted to establish the cause of this failure”, the statement reads.
