The Transmission Company of Nigeria TCN says the disturbance on the national grid earlier experienced Thursday, 7th November 2024, was as a result of sudden rise in frequency, and that the recovery efforts had commenced with electricity supply restored in some parts of the country within twenty eight minutes of occurrence.

TCN also adds that the frequency spike was caused by issues encountered at one of the substations.

It notes that due to the ongoing repair work on the transmission lines along the Shiroro–Mando axis, major upgrades at the Jebba Transmission Substation, and the restoration of the second Ugwuaji–Apir transmission line, some degree of instability in the system, TCN says, is likely to persist until all major works are completed.

TCN regrets the impact of these disruptions, and asks for the understanding and patience of the consumers as the company remains committed to improving the reliability of electricity supply.
