The Transmission Company of Nigeria has attributed Thursday’s nationwide power grid collapse to ongoing repair works in the sector.
In a statement, TCN spokesperson, Ndidi Mbah explained that the disturbance occurred at approximately 11:29 am, when the national grid experienced a sudden frequency rise from 50.33Hz to 51.44Hz.
Mbah further clarified that the disruption was a direct result of these repair activities, and the company is working to resolve the issue promptly to restore stability to the grid.
The TCN reassured the public that efforts are underway to minimize future occurrences and maintain a reliable power supply.
“Recovery efforts began immediately, and the Abuja Axis was restored within 28 minutes. Recovery is still ongoing,” she said, even though many residents reported they had yet to receive power supply since the first grid collapse on Tuesday.
“The frequency spike was caused by issues encountered at one of TCN’s substations, which had to be shut down to prevent further complications. In addition, we are actively engaged in significant repair works on several critical transmission lines and substations.
“This includes the 330kV transmission lines along the Shiroro–Mando axis, major upgrades at the Jebba Transmission Substation, and the restoration of the second Ugwuaji–Apir 330kV transmission line.
“Furthermore, following the submission of the investigative report on the causes of previous grid collapses, we have begun addressing the identified weaknesses in the transmission system.
“Efforts are being made to close the gaps highlighted in the report and to enhance the overall stability and resilience of the grid. These efforts include both technical upgrades and strategic interventions based on the committee’s recommendations,” Mbah stated.
However, she acknowledged that while the repairs and improvements are ongoing, some level of instability in the system is expected to continue until all major works are fully completed.
“We acknowledge the impact of these disruptions and ask for the understanding and patience of the public during this challenging period.
“TCN remains committed to improving the reliability of electricity supply, recognising the vital role that stable power plays in Nigeria’s socio-economic development.
“We assure the public that all necessary measures are being taken to ensure the grid’s long-term stability, in line with the recommendations of the investigative committee, while also addressing infrastructure damage, such as vandalised transmission lines,” she said.
It was earlier reported that, as Nigerians awaited full power restoration, the national grid collapsed once again on Thursday.
This followed a similar incident on Tuesday, bringing the total number of grid collapses to 10 since January 2024.
