TCN Restores National Grid After ‘System Disturbance’

The Transmission Company of Nigeria (TCN) has said it successfully restored the national grid following a ‘system disturbance’ that occurred at about 4:28pm on Thursday, March 28, 2024, with full recovery achieved by 10:00pm that same day.

It cited a report from the National Control Centre (NCC) in Osogbo, Osun State, saying the system disturbance was triggered by a significant reduction in generation capacity, primarily due to gas constraints.

“This reduction led to a rapid decline in system frequency. This created a sudden imbalance in the grid.

“The imbalance in grid stability was exacerbated by the sudden tripping of Egbin generation turbine 3, resulting in an additional loss of 167MW load and the subsequent collapse of the grid,” a statement by the general manager, Public Affairs, TCN, Ndidi Mbah, said on Friday.

The TCN spokesperson added that the grid has, however, since been recovered and is stable, and is currently transmitting all the generated power to distribution load centres nationwide.

“TCN emphasises its unwavering commitment to addressing grid challenges and actively working to mitigate disruptions. In instances where challenges extend beyond TCN’s control, the company collaborates with other stakeholders in the power sector value chain to minimize the impact and swiftly restore the grid to normal operation,” Mbah stated.
