The Transmission Company of Nigeria (TCN) has confirmed the full restoration of the national grid following a partial disturbance on Sunday morning at 11:21 a.m.

TCN’s general manager of Public Affairs, Ndidi Mbah, stated that immediate measures were taken to restore the affected part of the grid. The incident resulted in Ibom power islanded feeding Eket, Ekim, Itu, and Uyo transmission substations during the period of partial disturbance.

The total generation on the grid was 3,901.25 Mega Watts (MW) at 8 a.m., just over three hours before the partial collapse. It’s worth noting that low power generation has been an ongoing issue since January, exacerbated by gas constraints.

The National Control Centre (NCC) reported that prior to the partial disturbance, Sapele, Steam, and Egbin Substations lost 29.32MW and 343.84MW at 11:20:14 hrs and 11:20:17hrs respectively, totaling 373.16MW.

The combination of low power generation due to gas constraints and the sudden loss of generation capacity at the aforementioned substations led to the partial system disturbance. Mrs. Mbah emphasized that the constraints on gas supply continue to impact grid flexibility and stability, and ensuring sufficient gas supply to power generating stations is crucial for grid stability.

TCN also plans to investigate the cause of the tripping of Sapele Steam and Egbin power generating units in order to prevent similar incidents in the future.

In conclusion, the full restoration of Nigeria’s national grid is a significant step in ensuring stable and reliable power supply for the country.
