Nigeria’s Transmission Company (TCN) has attributed Thursday’s national grid collapse to ongoing repair works in the power sector.
According to TCN spokesperson Ndidi Mbah, the grid experienced a disturbance at 11:29 am due to a sudden frequency surge.
“Recovery efforts began immediately, with the Abuja Axis restored within 28 minutes. However, full recovery is still ongoing,” Ms. Mbah said.
The frequency spike was caused by issues at one of TCN’s substations, which was shut down to prevent further complications. Extensive repair works are underway on critical transmission lines and substations.
Upgrade Efforts
TCN is upgrading the 330kV transmission lines along the Shiroro-Mando axis and the Jebba Transmission Substation. Restoration of the second Ugwuaji-Apir 330kV transmission line is also in progress.
Following an investigative report on previous grid collapses, TCN is addressing identified weaknesses in the transmission system.
Challenges Ahead
Ms. Mbah warned that some instability in the system is likely to persist until all major works are completed.
“We acknowledge the impact of these disruptions and ask for the public’s understanding and patience during this challenging period.”
Background
