The Transmission Company of Nigeria (TCN) has explained the reason behind the collapse of the national grid on Thursday morning.
The Star had reported that the national grid collapsed at about approximately 11:29 a.m. on Thursday, November 7, 2024.
The latest collapse was the second of the incident this week. This was after the national grid collapsed on Tuesday, November 5.
However, the TCN, in a statement issued by its spokesperson, Ndidi Mbah, said the system collapse was caused by issues encountered at one of its substations.
Mbah noted: “TCN wishes to inform the public that the national grid experienced a disturbance at approximately 11:29am this morning, caused by a sudden rise in frequency from 50.33Hz to 51.44Hz. Recovery efforts began immediately, and the Abuja Axis was restored within 28 minutes.
“Recovery is still ongoing. The frequency spike was caused by issues encountered at one of our substations, which had to be shut down to prevent further complications.
“In addition to this, we are actively engaged in significant repair work 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.
“However, it is important to note that while these repairs and improvements are underway, some degree of 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 understanding and patience of the public during this challenging period.”
Mbah further reiterated the TCN’s commitment 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 vandalized transmission lines,” the TCN spokesperson added.
