After hours of a nationwide blackout on Sunday, the Transmission Company of Nigeria, TCN, has confirmed that the collapsed national grid has been restored.

Credible News earlier reported that the grid, on Sunday, collapsed for the first time in 2024, causing power outages nationwide.

A statement subsequently issued by TCN’s Public Affairs General Manager, Ndidi Mbah, said the blackout followed a partial disturbance experienced by the grid at about 11:21 hours on Sunday.

The statement noted that the incident affected the Ibom power island, feeding Eket, Ekim, Itu, and Uyo transmission substations.

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

“Before the incident, the total generation on the grid was 3,901.25 MW at 08:00 hours, a little over three hours before the time of partial collapse”.

The company, however, noted 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 today, Sapele Steam & Egbin Substations lost a total of 29.32MW & 343.84MW at 11:20:14Hrs & 11:20:17Hrs respectively, totaling 373.16MW.

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

“Gas constraints continue to impact grid flexibility and stability,” the statement added.
