Transmission Company of Nigeria (TCN) has dismissed claims by the Eko Electricity Distribution Company (EKEDP) over the recent power outage affecting parts of Lekki, insisting that the information released by the distribution company did not accurately reflect what transpired at the Lekki Transmission Substation.
In a statement issued by its management on Wednesday, TCN said it was compelled to correct what it described as misinformation published by EKEDP on August 26 concerning the incident.
According to TCN, contrary to EKEDP’s claim that its T11 transformer unexpectedly tripped and was awaiting inspection, investigations showed that the disruption originated from faults on EKEDP’s Oniru 33kV and Agungi 33kV feeders.
The company explained that the two feeders tripped simultaneously at about 4:34 a.m. on August 26 due to overcurrent and earth faults. It noted that the incident triggered the automatic tripping of the primary and secondary breakers on its TR1-60MVA 132/33kV transformer, accompanied by what it described as “a heavy bang and smoke.”
TCN said its maintenance engineers immediately mobilised to the site, repaired the damaged secondary breaker and successfully restored both the primary and secondary breakers later the same day.
However, the company disclosed that another interruption occurred when EKEDP attempted to re-energise the Oniru feeder.
According to the statement, “upon EKEDP’s trial closure of its Oniru feeder, the same relay indications caused another trip, necessitating further corrective work.”
Clarifying the situation, TCN maintained that “No outage occurred on TCN’s T11 transformer as claimed by EKEDP.” It added that “The incident was strictly related to EKEDP’s Oniru 33kV and Agungi 33kV feeders,” stressing that its technical personnel have remained on-site to restore electricity supply as quickly as possible.
The transmission company assured customers affected by the disruption that efforts were ongoing to resolve the fault linked to the distribution company’s feeders.
TCN also expressed regret over the inconvenience caused by the outage and reaffirmed its commitment to strengthening the nation’s transmission infrastructure, stating that it remains dedicated to “working assiduously to put in place a more robust transmission network.”
