The Transmission Company of Nigeria (TCN) has commenced a critical grid integration project to connect the newly built Bauchi 330kV Transmission Substation to the national grid.
The project involves the construction of a turn-in-turn-out (TITO) link on the existing 330kV Jos–Bauchi–Gombe transmission line.
In a statement released on Wednesday, TCN’s General Manager of Public Affairs, Ndidi Mbah, said the integration work began on June 10 and is scheduled for completion by June 14.
To ensure continued power supply during the operation, the Gombe and Biu substations will be served via the Dadin-Kowa Hydro Power Station and the Maiduguri Substation, with additional support from the Maiduguri Emergency Power Plant (MEPP).
However, TCN warned that the upgrade would result in a temporary reduction in power supply for some consumers under the Jos and Yola Electricity Distribution Companies.
Affected areas include Bauchi, Gombe, Ashaka, Savannah, Damaturu/Potiskum, and Biu, which may experience reduced power delivery.
Yola and Jalingo are expected to face full outages during the five-day window.
As part of the upgrade, a new transmission tower is being installed to strengthen grid reliability and flexibility.
TCN said the project will improve the system’s ability to withstand faults and support scheduled maintenance without major disruptions.
According to Mbah, the enhanced infrastructure will allow the Bauchi and Gombe substations to serve as backup for each other, increasing the system’s resilience.
Additionally, the Jos Substation will be able to supply power to Bauchi via a 132kV line if the primary 330kV link through Gombe is unavailable.
“This strategic enhancement not only improves power reliability but also diversifies transmission routes and strengthens our emergency response capacity,” Mbah said.
She reaffirmed TCN’s commitment to modernizing Nigeria’s electricity infrastructure and appealed for public understanding during the brief project period.
“Power supply will return to normal immediately after the completion of the grid integration project,” she assured.
