The Transmission Company of Nigeria (TCN) says it has commenced the construction of a turn-in-turn-out along the 330kV Jos – Bauchi – Gombe transmission line to connect the new Bauchi 330kV Transmission Substation to the grid.
TCN’s General Manager, Public Affairs, Ndidi Mbah, who announced the development in a statement on Wednesday said work began today, June 10, 2025, and is expected to be completed by June 14, 2025.
She explained that during the construction period, Gombe and Biu Transmission Substations would receive power through the Dadin-Kowa Hydro Power Plant and Maiduguri Substation, supported by the Maiduguri Emergency Power Plant (MEPP).
Mrs. Mbah further explained that following the arrangement, there will be a temporary reduction in bulk electricity supply to Jos and Yola Electricity Distribution Companies for onward distribution to their customers in Bauchi, Gombe, Ashaka, Savannah, Damaturu/Potiskum, and Biu.
She added that Yola and Jalingo would, however, experience full power outages during the five-day project duration.
The GM said a new transmission tower is also being installed to enhance the resilience and flexibility of the network, allowing the Bauchi and Gombe Substations to act as mutual backups in the event of maintenance or fault.
Additionally, she said Jos would be able to supply Bauchi Substation directly through a 132kV transmission line whenever the primary 330kV connection via Gombe is unavailable.
This arrangement, according to her, enhances power reliability, diversifies transmission routes, and improves emergency response efficiency.
Mbah said the company remains committed to strengthening Nigeria’s electricity infrastructure to facilitate a more stable and effective bulk power supply.
The company appealed for the patience of affected consumers during the period and assured that normal electricity delivery would resume immediately after the project’s completion.
