The Transmission Company of Nigeria (TCN) announced that it has effectively restored the national grid after a ‘system disturbance’ that occurred around 4:28 pm on Thursday, with its full recovery completed by 10:00 pm on the same day.
According to a report from the National Control Centre (NCC) in Osogbo, Osun State, the system disturbance was caused by a notable decrease in generation capacity, mainly attributed 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.
