Transmission Company of Nigeria (TCN) says power supply has been restored in some parts of the country.

Ndid Mbah, TCN’s spokesperson, in a statement, said the regions where power has been restored included the west, north-central, south, east, and a large portion of the northern states.

Earlier today, the national grid suffered a total system collapse for the first time in more than a year, according to the TCN.

The federal government had said the collapse of the national grid was caused by a fire outbreak on the Kainji/Jebba 330 kilovolt (kV) line.

Giving updates on the incident, Mbah said grid restoration has reached advanced stages.

Meanwhile, Managing Director of Aba Power Ltd, Patrick Umeh says the nationwide system collapse which began at 12.46 am today, is the reason residents in the industrial city of Aba, Abia State, were without electricity supply in the last 19hours.

Mr Umeh, a former Commissioner with the Nigeria Electricity Regulatory Commission (NERC) said Supply was restored at about 6 a.m., but it went off again within a couple of minutes”.

While apologising to customers in nine of the 17 local government areas in Abia serviced by Aba Power, Umeh said that APL, which is the newest in the country, is restoring light, now that the current national outage is over.
