Transmission Company of Nigeria warns of brief outages and schedules maintenance at Niger Substation

The Transmission Company of Nigeria (TCN) has announced a two-day maintenance exercise at its Zungeru Transmission Substation in Niger State, with temporary power interruptions expected in some areas.

In a statement issued on Wednesday, TCN’s General Manager, Public Affairs, Ndidi Mbah, said the maintenance will take place on February 18 and 19, 2026, between 11:00 a.m. and 5:00 p.m. each day.

The exercise will involve work on a 150MVA 330/132/33kV transformer, a 5.5MVA 33/11kV transformer, and associated switchgears at the facility.


According to the company, electricity supply will largely remain stable during the maintenance period, as loads will be transferred to a second 150MVA transformer within the same substation.

As a result, customers of the Abuja Electricity Distribution Company and the Kaduna Electricity Distribution Company particularly those connected to the transformer undergoing maintenance will continue to receive power.

However, TCN noted that residents in Kontagora, Tegina, Yauri, and surrounding communities will experience brief power interruptions during the load transfer process.
 

Mbah explained that the scheduled maintenance is part of routine efforts to ensure optimal performance and long-term efficiency of equipment at the substation. The company advised residents and businesses in the affected areas to plan accordingly.
