The Transmission Company of Nigeria (TCN) says it has restored the Omotosho-Ikeja West 330kV transmission line which tripped at the Omotosho end, causing the national grid to collapse.
In a statement, the General Manager, Public Affairs at TCN, Ndidi Mbah who announced this, recalled that the line which tripped at 11:34 am was on a scheduled outage for mechanical line tracing.
The statement explained that the tripping affected power supply to Lagos and Abuja.
“The Transmission Company of Nigeria (TCN) wishes to clarify that at 11:34 hours today, the Omotosho-Ikeja West 330kV transmission line tripped at the Omotosho end. At the time, the Benin-Egbin 330kV line was on a scheduled outage for mechanical line tracing.
“The tripping resulted in a cascaded outage affecting the Lagos, Abuja, and Osogbo axis. However all other parts of the grid remained unaffected, contrary to reports of a grid collapse in the media.
The line has been successfully restored, and normal power supply has been fully restored to the affected areas.
“We assure Nigerians of our commitment to efficient delivery of bulk power across the nation as we continue to implement measures to enhance the stability of the national grid,” it said.
Persecondnews reported on Wednesday that Nigeria’s national grid suffered its first collapse of 2025 from 1,214MW at 3pm to 0MW at 4pm on the Nigerian Electricity Supply Industry (NESI).
