THE Transmission Company of Nigeria (TCN) has admitted experiencing a power failure that caused the loss of power supply to all the Egbin Transmission Substation’s outgoing lines.

It stated this in a statement on Tuesday, August 6 by its Group Managing, Public Affairs, Ndidi Mbah.

It said, “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.”

The TCN claimed that 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,” it added.

Some DisCos cited grid collapse as part of reason for poor supply of power on Monday,August 5.

In a statement on Monday shared on its X handle, the Abuja Electricity Distribution Company (AEDC) said there was a grid collapsed at 2.30 pm.

“We understand that some of our customers are still without power due to a system failure from the national grid at 2.55 pm today, 5th August 2024,” AEDC posted.

The ICIR can report that the national electricity grid collapse has been a recurrent issue, plunging several cities across Nigeria into darkness.

The ICIR reported that there have been concerns over the national grid not being unreliable, failing consumers on more than 141 occasions, despite the government privatising the sector over eleven years ago.
