The national grid restoration has been completed following its collapse on Wednesday.
The General Manager of the Transmission Company of Nigeria (TCN), Ndidi Mbah, who disclosed this in a statement, said the national grid experienced system disturbance at about 11.27 am on Wednesday, 20th, July 2022.
Mbah added that the collapse was a result of a sudden drop in system frequency from 49.94Hz to 47.36Hz, which created system instability.
She explained that the 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,” she added.
The GM said the Nigerian Electricity Supply Industry is 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.
Mbah discloed that a full-scale investigation is being conducted to establish the cause of this failure.
