Abuja, March 29, 2024 – The Transmission Company of Nigeria (TCN) says it has successfully restored the national grid following a “system disturbance” that occurred at about 4:28 pm on Thursday, March 28, 2024.

Ndidi Mbah, the TCN General Manager (Public Affairs), said this in a statement on Friday.

The TCN said full recovery was achieved on the grid by 10:00 pm that same day.

It said a report from the National Control Centre (NCC) in Osogbo, Osun State, indicated that 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.”

The TCN said the grid has, however, since been recovered and stable and 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,” the statement said. (GBN)
