The company apologized for the inconvenience caused by the temporary outages, stressing that the maintenance exercise is necessary to improve the efficiency and reliability of power transmission in the state.

Earlier, Legit.ng reported that millions of electricity consumers across Northern Nigeria are expected to experience a temporary blackout after the Transmission Company of Nigeria, TCN, announced the shutdown of a critical transmission line for emergency maintenance.
The planned outage affects Kano, Katsina, Jigawa, Bauchi, and Yobe states, while communities in neighbouring Niger Republic that rely on electricity supplied through Nigeria’s national grid will also experience disruptions.
In a statement issued by TCN spokesperson Ndidi Mbah, the company explained that the interruption became necessary to allow engineers to carry out urgent maintenance work on the Mando-Kumbotso 330kV transmission line, one of the major power corridors serving the North-West and parts of the North-East.
