The Transmission Company of Nigeria (TCN), late on Sunday night, confirmed the full restoration of the collapsed national grid, after hours of nationwide blackout.
The national grid collapsed earlier on Sunday, causing power outage nationwide.
A statement issued subsequently by TCN’s Public Affairs General Manager, Ndidi Mbah, said the blackout followed partial disturbance experienced by the grid about 11:21hours on Sunday.
The statement noted that the incident affected the Ibom power islanded, feeding Eket, Ekim, Itu and Uyo transmission substations.
Mbah said: “TCN initiated immediate restoration of the affected part of the grid, and presently, the grid is fully restored.
“Prior to the incident, the total generation on the grid was 3,901.25 MW at 08:00Hours, 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.
