The Transmission Company of Nigeria (TCN) has extended the ongoing maintenance work on the Jos–Bauchi–Gombe 330kV single-circuit transmission line until June 30, 2026, to facilitate the completion of the Optical Ground Wire (OPGW) installation project along the corridor.

TCN disclosed this in a statement issued over the weekend by its General Manager, Public Affairs, Ndidi Mbah.

According to the company, the maintenance exercise, which began earlier this year, was extended to enable contractors complete the OPGW stringing project along the 276-kilometre Jos–Bauchi–Gombe transmission line.

The company explained that the ongoing work will affect electricity supply to customers served by the Yola Electricity Distribution Company (YEDC) and Jos Electricity Distribution Company (JEDC) in Bauchi, Gombe, Damaturu and Maiduguri.

TCN stated that affected customers would experience limited power supply between 9:00 a.m. and 6:00 p.m. from Thursdays to Sundays throughout the maintenance period.

It added that Yola, Jalingo and neighbouring communities would remain without electricity during the outage periods, noting that power supply would be restored at the end of each day’s maintenance activities.

The transmission company apologised for the inconvenience the outages may cause and assured customers that efforts were being intensified to ensure the project is completed within the stipulated timeframe.

According to TCN, the completion of the OPGW installation and related maintenance work will improve grid monitoring, enhance operational efficiency and strengthen the reliability of electricity transmission across the affected areas.

Meanwhile, residents of Taraba State have continued to grapple with unstable electricity supply over the past month, a situation that has reportedly disrupted economic activities and negatively affected small businesses across the state.

Many business owners have expressed concerns over mounting operational costs as they increasingly rely on alternative power sources to sustain their operations amid the prolonged power challenges.
