The Transmission Company of Nigeria (TCN)says the National grid which collapsed at 11:21am on Sunday, Feb. 4 has been restored.

This is contained in a statement by Ndidi Mbah, TCN General Manager, Public Affairs Department.

She said the total generation on the grid before the partial collapse was 3,901.25 MW at 08:00Hours.

“The grid experienced a partial disturbance at about 11:21Hours with Ibom power islanded, feeding Eket, Ekim, Itu and Uyo transmission substations, during the period of partial disturbance.

“TCN initiated immediate restoration of the affected part of the grid and presently the grid is fully restored.

“It is important to note that low power generation has persisted since January 2024 to date, exacerbating daily due to the lingering gas constraint.

“According to the National Control Center (NCC), the Internet of Things (IoT) revealed that just before the partial disturbance, which occurred at 11:21Hrs, Sapele Steam & Egbin Substations lost a total of 29.32MW and 343.84MW at 11:20:14Hrs & 11:20:17Hrs respectively, totalling 373.16MW.

“This, combined with the current low power generation due to gas constraints, caused the imbalance leading to the partial system disturbance,”she said.

Mba further said “Gas constraints continue to impact grid flexibility and stability.

Ensuring sufficient gas supply to power generating stations is crucial for grid stability as sufficient generation allows for better grid management in the event of sudden generation losses like this.

The general made assured that TCN would investigate the cause of tripping of Sapele Steam and Egbin power generating units.
