Following reports of setbacks to Nigeria’s national grid on Wednesday, the Transmission Company of Nigeria (TCN) has linked the ‘disturbance’ to tripping of Omotosho-Ikeja West 330kV transmission line.
TCN’s General Manager on Public Affairs, Ndidi Mbah, disclosed in a statement that at the time, the Benin-Egbin 330kV line was on a scheduled outage for mechanical line tracing.
According to her, the tripping resulted in a cascaded outage affecting the Lagos, Abuja, and Osogbo axes.
She, however, clarified that aside from this axis, all other parts of the grid remained unaffected, condemning “reports of a grid collapse in the media.”
The line had been successfully restored, and normal power supply had been fully restored to the affected areas, she declared.
“We assure Nigerians of our commitment to efficient delivery of bulk power across the nation as we continue to implement measures to enhance the stability of the national grid.”
There was a blackout in parts of the country from 11:34am on Wednesday as the national grid suffered ‘disturbance’.
The loss of supply on Wednesday, which, according to a check on the website of the Independent System Operator (ISO), an independent arm of the Transmission Company of Nigeria, showed the average electricity supply on the grid dropped from an average of 4064.70 megawatt around 11am to 1,222.78 MW around 12pm, was also confirmed by distribution companies.
The Abuja Electricity Distribution Company (AEDC), while confirming the disturbance in a statement posted on its X account (formerly Twitter), said it stopped receiving electricity supply in its franchise area at 11:38am.
The statement said: “We regret to inform you that a system disturbance occurred on the national grid at 11:34 am today causing power outage across our franchise areas.
“While gradual restoration of power supply has commenced, please be assured that we are working closely with relevant stakeholders to fully restore electricity as soon as the grid is stabilised.
“Thank you for your understanding and patience as we work to serve you better.”
Also, Ikeja Electric, in a statement shared via its X account, announced that the company was experiencing system outage at about 11:34am, affecting all its feeders. Tribune
