TCN Power Maintenance at Katampe Substation, Lists Abuja, Niger Communities to Experience Disruption By Raymond Enoch

The Transmission Company of Nigeria (TCN) has announced a scheduled maintenance exercise at its Katampe 330/132/33kV Transmission Substation, a critical power transmission facility serving parts of the Federal Capital Territory (FCT) and neighbouring communities in Niger State.

The maintenance, scheduled for Saturday, October 31, 2026, is aimed at ensuring the operational efficiency and reliability of critical transmission infrastructure, as the company moves to sustain the stability of electricity supply across its network.

In a notice issued on Friday, TCN Management disclosed that its maintenance crew would undertake scheduled maintenance on the 150MVA Power Transformer 2 and associated switchgear at the Katampe Transmission Substation between 9am and 4pm.

The exercise will temporarily affect electricity off-take by the Abuja Electricity Distribution Company (AEDC), which will be unable to receive power from the affected transmission facility for onward distribution to customers in the designated areas during the maintenance period.

According to the management, the affected locations include Kubwa PW, Dutse Makaranta, Ushafa, Jere, Jiwa, parts of Suleja, Kaduna Road, Sabon Wuse, Dikko, Zuba, Madalla, Dakwa, Tugan Maje and adjoining communities.

TCN, however, clarified that the anticipated disruption to electricity supply would last for six hours only, despite the seven-hour maintenance window, indicating that the interruption is expected to be limited to the period required for the critical maintenance operations.

The exercise underscores the company’s continuing responsibility to maintain, strengthen and safeguard the national transmission network through scheduled interventions on critical equipment, particularly power transformers and associated switchgear that facilitate the transmission and evacuation of electricity.

While appealing for the understanding of electricity consumers in the affected communities, TCN Management apologised for the inconvenience the temporary interruption might cause, assuring the public that the maintenance was part of its scheduled operational activities.

The company reiterated the importance of such maintenance interventions in sustaining the integrity of transmission infrastructure and supporting reliable electricity delivery to distribution companies and, ultimately, end users.
