The Transmission Company of Nigeria (TCN) has disputed claims by the Eko Electricity Distribution Company (EKEDC) and Kaduna Electric over transmission-related incidents affecting electricity supply in parts of Lagos and Jos, Plateau State capital.
TCN General Manager, Public Affairs, Mrs Ndidi Mbah, in separate statements, said the claims by the two distribution companies misrepresented the actual situations at the Lekki Transmission Substation in Lagos and in Jos.
On the Lekki incident, Mbah said “the outage recorded on August 26 was caused by the simultaneous tripping of EKEDC’s Oniru and Agungi 33-kilovolt feeders due to overcurrent and earth fault.”
According to her, “the fault resulted in the inter-tripping of the primary and secondary breakers of TCN’s TR1 60-megavolt-ampere transformer.”
She said TCN’s maintenance team restored the breakers the same day, but another trip occurred when EKEDC attempted to close the Oniru feeder, requiring further corrective work.
“The company therefore rejected EKEDC’s claim that its T11 transformer had tripped unexpectedly and was awaiting inspection,” she said.
Similarly, TCN dismissed Kaduna Electric’s claim that transmission constraints were responsible for power supply challenges in Jos and its environs.
It said all 330-kilovolt transmission lines connected to Jos were in service and transmitting bulk power.
According to TCN, “the Jos-Lafia 330-kilovolt Line Two circuit breaker was opened on August 23 for voltage control as part of routine measures to maintain grid stability, and was restored on August 24.”
TCN maintained that there had been no disruption of bulk electricity transmission on any 330-kilovolt line supplying Jos since the restoration.
The company urged distribution companies to verify facts with TCN before issuing public statements, while assuring electricity consumers of its commitment to stable and reliable power supply.
