“The Transmission Company of Nigeria (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,” the statement reads.
The Transmission Company of Nigeria says instability in the national grid will likely persist as the system undergoes repairs after another round of shutdown.on Thursday — the second time in 72 hours — leaving the country in darkness.

Recovery is still ongoing,” the statement reads. The facilities, according to Mbah, include 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.The public affairs manager said following the submission of the investigative report on the causes of previous grid collapses, TCN has started working to address the identified weaknesses in the transmission system.
“These efforts include both technical upgrades and strategic interventions based on the committee’s recommendations,” she added.“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.”
