The Transmission Company of Nigeria (TCN) has dismissed as inaccurate a publication by the Eko Electricity Distribution Company (EKEDP) concerning an outage incident at the Lekki Transmission Substation on August 26, 2026.

TCN, in a statement signed by Management on Thursday, said contrary to EKEDP’s claim that its T11 transformer tripped unexpectedly and was awaiting inspection, the incident actually involved the simultaneous tripping of EKEDP’s Oniru 33kV and Agungi 33kV feeders at about 4:34am.

According to the transmission company, the feeders tripped due to overcurrent and earth fault, resulting in the inter-tripping of TCN’s TR1 60MVA, 132/33kV transformer primary and secondary breakers.

TCN said the incident was accompanied by a heavy bang and smoke, prompting its maintenance crew to respond immediately.

The company explained that its technical team rehabilitated the damaged secondary breaker and restored both the primary and secondary breakers later the same day.

However, TCN said another trip occurred when EKEDP attempted a trial closure of its Oniru feeder, as the same relay indications were observed, necessitating further corrective work.

TCN stressed that there was no outage on its T11 transformer as claimed by EKEDP, insisting that the incident was strictly related to EKEDP’s Oniru and Agungi 33kV feeders.
“The TCN technical team has been on-site, working assiduously to restore supply within the shortest possible time,” the company said.

TCN assured electricity customers affected by the incident that it was actively addressing the fault and regretted the inconvenience caused.

The company reaffirmed its commitment to strengthening the transmission network and ensuring a more robust and reliable electricity supply system.
The statement was dated August 27, 2026.
