TCN Schedules Two-Day Irrua Substation Maintenance, Power Supply to Five Feeders to Be Affected By Raymond Enoch

The Transmission Company of Nigeria (TCN) has announced a two-day maintenance exercise at its Irrua 132/33kV Transmission Substation, with electricity supply to customers served by five 33kV feeders expected to be disrupted during the scheduled works on November 2 and 3, 2026.

In a public notice signed by TCN Management, the company said the exercise, scheduled to run from 10:00 a.m. to 5:00 p.m. each day, would enable its contractors to commission the SERGI fire protection system installed on the substation’s 100MVA transformer.

TCN explained that the maintenance was necessary to facilitate the commissioning of the fire protection system, an installation intended to strengthen safety measures around the critical transmission equipment.

Consequently, the Benin Electricity Distribution Company (BEDC) will be unable to off-take bulk electricity for onward distribution to customers served by the Ehor, Uzebba, Ubiaja, Ekpoma and Agbor 33kV feeders throughout the maintenance periods.

The planned exercise is expected to affect electricity supply to consumers within the areas served by the affected feeders during the specified hours on both days.

The commissioning of the SERGI fire protection system forms part of the work required to enhance protection for the transformer, a key component of the transmission infrastructure serving the affected electricity distribution network.

TCN apologised to electricity consumers for the inconvenience the planned maintenance may cause, appealing for their understanding and cooperation as its contractors undertake the scheduled work.

The company advised customers in the affected areas to take note of the maintenance schedule and make necessary arrangements for the temporary interruption in electricity supply.
