TCN restores national grid after ‘system disturbance’

Transmission Company of Nigeria (TCN) said it has restored the national grid following a system disturbance that occurred at 4:28 pm on Thursday, 28th March 2024.

It blamed the incident on significant reduction in generation capacity, primarily due to gas constraints.

In a statement issued on Friday, the Company’s Spokesperson, Ndidi Mbah said the grid was fully recovered at 10:00 pm on Thursday.

It said a report from the National Control Centre (NCC) in Osogbo, had stated that reduction led to a rapid decline in system frequency thus creating 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.

“The grid has, however, since been recovered and is stable, and is currently transmitting all the generated power to distribution load centres nationwide,” it said.

TCN emphasized its 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 minimise the impact and swiftly restore the grid to normal operation,” the statement added.
