TCN Restores National Grid After System Collapse

The Transmission Company of Nigeria (TCN) has successfully restored the national grid following a system collapse at 4:28 p.m. on Thursday.

The TCN in a statement on Friday evening, announced that complete recovery had been achieved by 10:00 p.m. on the same day

The TCN revealed that a report from the National Control Centre (NCC) in Osogbo, indicated that the system disturbance was triggered by a significant reduction in generation capacity, primarily due to gas constraints.

The Transmission Company expressed that the reduction led to a rapid decline in system frequency, creating a sudden grid imbalance.

It added that the imbalance in grid stability was exacerbated by the sudden tripping of Egbin generation turbine 3, resulting in an additional loss of 167 MW and the subsequent collapse of the grid.

The statement partly reads; “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 minimize the impact and swiftly restore the grid to normal operation.”
