The Transmission Company of Nigeria (TCN) has announced that there would be power outages in Abuja and parts of Enugu State, respectively, due to maintenance of its Kubwa and New Haven Enugu 132/33 kilovolt substations.
The spokesperson of TCN revealed this in a separate statement released on the agency’s X account on Tuesday.
According to TCN, the scheduled Enugu-New Haven maintenance would take effect from October 22, 2025, to Thursday, October 31, 2025, between 9:00am and 5:00pm daily.
TCN stated that as a result of the maintenance, there would be disruption of bulk electricity supply to one 33-kilovolt feeder per day on a rotational basis during the period.
“TCN wishes to clarify that this is not a total system shutdown for Enugu State. To minimise disruption, the work has been carefully planned to affect only one 33 kV feeder per day on a rotational basis. Given that Enugu State is supplied by twenty-four (24) 33 kV feeders, this arrangement ensures that most parts of the state will continue to receive a power supply while the maintenance is ongoing.
“The exercise requires the temporary isolation of specific 33 kV feeders to ensure the safety of TCN technical crews and the protection of equipment under maintenance.
“Consequently, customers in areas served by these feeders will experience power interruption only on the day their specific feeder is isolated,” the statement reads.
In Abuja, the disruption, which is expected to take effect on 21st October 2025, would affect areas in Kubwa, including Army Resettlement, Papal Ground, Aso Garden, Nydren Supermarket, Back of AT4, Back of Mobil, Zenith Bank, FO1, Kubwa Extension, Chikakore Community, Dantata Estate, IITA Farms, Royal Champion Church, the Kubwa area and environs.
“The Transmission Company of Nigeria (TCN) notifies the public of scheduled preventive maintenance at the Kubwa 132/33 kV Transmission Substation on October 21, 2025, from 11 am to 3 pm.
“The exercise will involve the replacement of a 33 kV circuit breaker with a new one and will require an interruption of bulk power supply to the Abuja Electricity Distribution Company (AEDC) from Kubwa Substation,” the statement reads.
