The national electricity grid system suffered collapse on Wednesday, causing it to lose an estimated 1,658mw.
The Transmission Company of Nigeria (TCN) confirmed the system disturbance, on Wednesday in Abuja but noted that it was revived shortly after, reducing power generation to 2,900 megawatts.
A statement from TCN noted that the incident occurred at 1:00am but the cause of the system collapse was yet to be ascertained.
The General Manager, Public Affairs at TCN, Ndidi Mbah, said the National Control Centre (NCC) of TCN in Osogbo commenced immediate restoration of the grid which has been completed nationwide except for that of the Eastern region.
The power grid is expected to return to its full capacity of 4000mw once TCN restores major transmission lines in the East.
Mrs Mba noted, “TCN would commence investigations into the cause of the supply loss as soon as full recovery is achieved.
“We are committed to ensuring grid stability and consistent bulk power supply, especially at this time of the pandemic.”
