The Transmission Company of Nigeria (TCN) has announced a scheduled seven-hour power outage in parts of the Federal Capital Territory (FCT) on Saturday, April 12, 2025, to carry out critical preventive maintenance work on a key transformer at the Katampe Transmission Substation.
The outage will occur from 9:00 a.m. to 4:00 p.m., affecting electricity supply to several communities including Mpape, Maitama, Jahi, Life Camp, Kado Fish Market, Idu-Karmo, and surrounding areas.
Maintenance Details and Reason for Outage
In a statement issued in Abuja, TCN's General Manager of Public Affairs, Mrs Ndidi Mbah, explained that the temporary blackout is necessary to enable engineers to conduct preventive maintenance on the 100 Mega Volt Ampere (MVA) 132/33 Kilovolt (kV) Power Transformer (TR1) at the Katampe 132/33kV Transmission Substation.
According to her, the maintenance exercise will also cover the transformer's auxiliary equipment and associated switchgear to ensure the facility continues to operate safely and efficiently. She noted that the work forms part of TCN's routine efforts to improve the reliability and stability of electricity transmission across the nation's capital.
Areas Affected and Customer Advisory
During the maintenance period, the Abuja Electricity Distribution Company (AEDC) will be unable to receive bulk power from the Katampe Transmission Substation for onward distribution. As a result, electricity supply will be temporarily interrupted in the following areas: Mpape, Maitama, Jahi, Life Camp, Kado Fish Market, Idu-Karmo, and surrounding communities.
Customers in these locations are advised to make adequate arrangements ahead of the scheduled outage.
TCN Appeals for Understanding
TCN expressed regret over the inconvenience the temporary power interruption may cause residents and businesses in the affected communities. The company stressed that preventive maintenance remains essential for ensuring the long-term reliability and efficient performance of critical transmission infrastructure.
It assured customers that the power supply would be restored immediately after the maintenance work was completed, provided there were no unforeseen technical issues.
Recent Power Outages in Other States
In a related development, TCN recently reported a forced outage on the Alaoji 132kV Transmission Line, which occurred at approximately 3:59 am on Tuesday, June 23, 2026, cutting off electricity supply to customers in Owerri, Yenagoa, and Ahoada. The announcement was made via TCN's official X account. Mrs Mbah attributed that outage to an earth fault and distance protection failure on the line.
As a result of that disruption, the Port Harcourt Electricity Distribution Company (PHEDC) has been unable to off-take electricity supply for distribution to its customers across the three affected areas — Owerri in Imo State, Yenagoa in Bayelsa State, and Ahoada in Rivers State.
