TCN Successfully Restores Grid After ‘A System Disturbance’

The Transmission Company of Nigeria (TCN) has announced the successful restoration of the national grid following a system disturbance that occurred at 4:28 p.m. on Thursday, March 28, 2024. The full recovery was achieved by 10:00 p.m. on the same day.

Ndidi Mbah, the General Manager of Public Affairs, has stated that a report from the National Control Centre (NCC) in Osogbo has revealed that the system disturbance occurred due to a significant reduction in generation capacity. The primary reason for this reduction was the constraints related to gas supply.

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

“TCN emphasizes 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 minimise the impact and swiftly restore the grid to normal operation”.
