Bulk power restoration has started, according to the Transmission Company of Nigeria (TCN), hours after another national grid collapse plunged Nigeria into darkness.
TCN spokesperson Ndidi Mbah disclosed this in a statement, confirming that the grid collapsed for twelve times around 11:29 am on Thursday.
Nigeria experienced another round of darkness on Thursday after the national grid collapsed for the second time this week, according to earlier reports from Persecondnews.
Reacting to the latest collapse, TCN said: “The frequency spike was caused by issues encountered at one of our substations, which had to be shut down to prevent further complications.
“The Transmission Company of Nigeria (TCN) wishes to inform the public that the national grid experienced a disturbance at approximately 11:29 am this morning, caused by a sudden rise in frequency from 50.33 Hz to 51.44 Hz.
“Recovery efforts began immediately, and the Abuja Axis was restored within 28 minutes. Recovery is still ongoing.
“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.”
