TCN restores collapsed national grid after hours of outage

The Transmission Company of Nigeria, TCN, says  the collapsed national grid has been fully restored.

Within Nigeria had earlier reported that the whole country was tosssed into darkness on Sunday after the grid collapsed for the first time in 2024

However, a statement subsequently issued by TCN’s Public Affairs General Manager, Ndidi Mbah, confirmed the restoration of the collapsed grid.

He disclosed the blackout was caused by 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

According to Ndidi, the “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, totalling 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
