The Transmission Company of Nigeria (TCN) has dismissed as inaccurate a publication by the Eko Electricity Distribution Company (EKEDP) concerning an incident at the Lekki Transmission Substation on August 26, 2026.
TCN, in a statement signed by its Management and issued on August 27, said contrary to EKEDP’s claim that its T11 transformer tripped unexpectedly and was awaiting inspection, the incident involved the simultaneous tripping of EKEDP’s Oniru and Agungi 33kV feeders at about 4:34 a.m.
According to the company, the feeders tripped due to overcurrent and earth fault, which resulted in the inter-tripping of the primary and secondary breakers of TCN’s TR1 60MVA, 132/33kV transformer.
The incident was accompanied by a heavy bang and smoke, prompting TCN’s maintenance crew to respond immediately.
TCN said its maintenance team rehabilitated the damaged secondary breaker and restored both the primary and secondary breakers later the same day.
However, it explained that another trip occurred when EKEDP attempted a trial closure of its Oniru feeder, as the same relay indications reappeared, requiring further corrective work.
TCN stressed that no outage occurred on its T11 transformer as claimed by EKEDP, adding that the incident was strictly associated with EKEDP’s Oniru and Agungi 33kV feeders.
The company said its technical team remained on site and was working to restore electricity supply to affected customers as quickly as possible.
“TCN assures electricity customers impacted by the incident that we are actively addressing the fault caused by the DisCo's feeders and regrets any inconvenience caused,” the statement said.
The transmission company reaffirmed its commitment to strengthening the nation’s transmission infrastructure and putting in place a more robust transmission network.
