TCN Restores Grid, Explains Cause Of Transmission System Disturbance

The Transmission Company of Nigeria (TCN ) has successfully restored the national grid even as it explains the cause of the transmission system collapse on Thursday.

OPTIMUM TIMES recalls that a system disturbance occurred at 4:28 p.m. on Thursday, 28th March 2024, while full recovery was achieved at 10:00  p.m. that same day.

The TCN General Manager Public Affairs, Mrs Ndidi Mbah, gave details of the system disturbance in a statement Friday.

She said: “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.

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

Mrs Mbah emphasised TCN 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”, she said.
