The TCN announced that its “maintenance crew will carry out scheduled preventive maintenance on the bay of its T1A 150MVA, 330/132/33kV transformer bay” on Thursday and Friday, January 18 and 19, 2024.

According to a statement by the TCN General Manager, Public Affairs, Ndidi Mbah, the maintenance would last eight hours, running from 9 am to 5 pm on each day.

Mbah disclosed that to commence the maintenance exercise, “TCN would transfer the load from T1A 150MVA transformer to its T2A 150MVA transformer in the same substation”.

She added that consequently, there would be “an interruption of bulk power supply to Jos and Yola DisCos through the T1A transformer”.

She clarified that the interruption would only affect bulk supply during the transfer period only, and not for the entire eight-hour period it would take to complete the maintenance exercise on both days.

“The short outage during the transfer period would affect supply to Gombe and some parts of Yola and Bauchi states only, during transfer time on both days.

TCN will, however, restore bulk power supply through the transformer immediately after the maintenance exercise,” Mbah explained.

The transmission company regretted “any inconvenience this may cause electricity consumers within the affected areas”.

The TCN maintenance crew had on Saturday carried out scheduled preventive maintenance on the Jos-Lafia 330kV transmission lines, which it said had been redundant for some time.
