The Transmission Company of Nigeria (TCN) has extended maintenance on the 330kV Jos–Bauchi–Gombe single-circuit power line to allow contractors to finish an optical ground wire (OPGW) installation along the corridor, with outages expected to run through late June 2026.
Maintenance extension and scope
- TCN said the maintenance work, which began earlier this year, has been pushed back to continue until June 30, 2026.
- The transmission operator linked the extension to the need for contractors to complete OPGW stringing on the 276-kilometre Jos–Bauchi–Gombe transmission line stretch.
- TCN warned that the maintenance will disrupt electricity delivery to customers served by the Yola Electricity Distribution Company (YEDC) and the Jos Electricity Distribution Company (JEDC).
- The affected service areas include parts of Bauchi, Gombe, Damaturu, and Maiduguri.
- For the duration of the maintenance window, TCN said customers should expect restricted power supply from 9:00 a.m. to 6:00 p.m. from Thursdays through Sundays.
- The company added that Yola, Jalingo, and surrounding communities are expected to remain without electricity during the outage periods.
- TCN stated that electricity would be restored at the end of each day’s maintenance activity.
In its statement, TCN expressed regret for the disruption the work may cause, while stressing that efforts are being intensified to complete the project within the agreed timeframe.
Why the OPGW project matters
TCN said finishing the OPGW installation and the associated maintenance is expected to improve grid monitoring, raise operational efficiency, and strengthen the reliability of power transmission across the affected regions.
The announcement comes as businesses and residents in parts of Taraba State have already been dealing with unstable electricity supply for more than a month, with the power shortfall reportedly weighing on small enterprises across the state.
