Grid restored after system disturbance – TCN

The Transmission Company of Nigeria (TCN) has said the national grid has been restored after a system disturbance, which occurred on Thursday.

The company said that the disturbance occurred at 4:28 p.m. on Thursday with full recovery of the grid achieved by 10:00 p.m. on the same day.

 TCN’S General Manager Public Affairs, Mrs. Ndidi Mbah, said this in a statement in Abuja on Friday.

Mbah said that according to a report from the National Control Centre (NCC) in Osogbo, 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,” she said.

She said that the grid had since been recovered and was stable, adding that it was currently transmitting all the generated power to distribution load centres nationwide.

She expressed TCN’s 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.” (NAN)
