The Transmission Company of Nigeria (TCN) has recovered the national grid less than 24 hours system disturbance occured leading to collapse of grid.
The grid experienced system disturbance at about 11.27am Wednesday, 20th, July 2022, resulting to sudden drop in system frequency from 49.94Hz to 47.36Hz, which created system instability.
A statement by the TCN General Manager, Public Affairs, Mrs Ndidi Mbah said: “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”.
She explained that the unwholesome event pulled out other grid-connected Units in the plant and resulted in aggregated generation loss of 457MW.
She noted that the 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 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”, Mbah stated.
