The Transmission Company of Nigeria (TCN) says it has successfully restored the national grid following a system grid collapse. 

The national electricity grid, centrally managed from Osogbo, Osun state, suffered a collapse for the second time in 2024 at 4.30 pm on March 28.

In a statement on Friday by Ndidi Mbah, TCN’s spokesperson, the company said full recovery was achieved by 10.00 pm on the same day.

Citing a report from its national control centre (NCC) in Osogbo, TCN said the system disturbance was caused by a significant drop 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,” TCN said.

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

TCN emphasised its unwavering commitment to addressing grid challenges and actively working to reduce disruptions. 

In instances where challenges exceed TCN’s control, the company said it will work with other stakeholders in the power sector value chain to mitigate the impact and swiftly restore the grid to normal operation.
