The restoration of the national grid has been completed following its collapse on Wednesday.
The Transmission Company of Nigeria (TCN) made this known, adding that the incident was a result of sudden drop in system frequency from 49.94Hz to 47.36Hz, which created system instability.
The National Control Centre (NCC) stated that 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”.
According to the General Manager of the TCN, Ndidi Mbah, the event resulted in aggregated generation loss of 457MW. In its wake, a train of events ensued – culminating in the collapse of the national grid.
She further noted that “as obtainable in all systems, when a component of the electric power system is defective, the entire configuration is vitiated. However, in spite of setbacks encountered at the initial stage, grid restoration had almost been completed as of 11:00 p.m. when this report was filed.”
While appreciating the kind understanding of the Government and consumers of electricity within and outside the country, 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.
