National Grid Did Not Collapse, It Was Only A Tripped Line – TCN

The Transmission Company of Nigeria (TCN) has denied reports of a national grid collapse on Monday.

The TCN, in a statement on Tuesday, said it was only a tripped line at the Benin-Egbin 330kV isolator that caused a blackout in some parts of the nation on Monday.

The TCN spokesperson, Ndidi Mbah, clarified that the arcing on the Benin-Egbin 330kV did not result in the collapse of the grid system but did affect the power supply in some areas of the country.

He stated that the line tripping began around 2:47 p.m. yesterday, caused by a significant system surge that resulted in the arcing of the Benin-Egbin 330kV line isolator fingers at the Egbin Transmission Substation switchyard.

Mbah added that the issue has been resolved, and power supply has been restored to the substation.

“The Transmission Company of Nigeria (TCN), hereby notes that at about 6:10 pm yesterday, 5th August 2024, power supply was restored to areas that had been affected by the arcing on the Benin-Egbin 330kV isolator which caused lines tripping and consequent loss of supply to some areas. However, contrary to media reports, the incident did not cause a system collapse.

“The lines tripping started earlier at about 2:47 p.m. yesterday, with a heavy system surge that led to the arcing of Benin–Egbin 330kV line isolator fingers at the Egbin Transmission Substation switchyard.

“This resulted in a tripping at the Egbin Generating Station, which caused the loss of power supply to all the Egbin Transmission Substation’s outgoing lines.

“The line tripping was quickly rectified, enabling the grid controller to restore full bulk power supply through the transmission lines at about 6.10 pm yesterday,” he said.
