The Transmission Company of Nigeria said it has fully restored the national electricity grid which collapsed in the early hours of Monday.

This was announced by the TCN General Manager, Public Affairs, Ndidi Mbah, in a statement Monday afternoon.

Earlier, the grid collapsed from 2,583.77MW at 2 am on Monday to 64.7MW around 3 am.

This makes it the sixth time the power grid collapsed in 2024.

However, Mbah said the collapse of the national grid was caused by a fire outbreak at the Afam power generating station.

“The Transmission Company of Nigeria (TCN) announces the full restoration of the national grid following a fire incident at the Afam power generating station, which caused a partial disturbance of the nation’s grid.

“At 02:41Hrs today, 15th April 2024, a fire erupted at the Afam V 330kV bus bar coupler, leading to the tripping of units at Afam III and Afam VI. This resulted in a sudden generation loss of 25MW and 305MW respectively, destabilizing the grid and causing a partial collapse.

“During the incident, the Ibom Power plant was isolated from the grid and was supplying parts of the Port Harcourt Region. This further minimized the effect of the system disturbance. TCN confirms that the affected section of the grid has been fully restored and stabilised,” she said.

She added that the company would continue to invest in measures that will strengthen the grid infrastructure.

“TCN reaffirms its commitment to enhancing the resilience and reliability of the national grid and pledges to continue investing in measures aimed at strengthening the grid infrastructure,” the statement concluded,” she assured.
