There was a national grid collapse on Wednesday.
The Transmission Company of Nigeria (TCN) says it has restored bulk power to all the 330 Kilo Volt (kV)Transmission Stations across the entire grid by 5.54 p.m. Wednesday.
TCN's General Manager, Ndidi Mbah, made this known in a statement in Abuja on Thursday.
It would be recalled that there was a national grid collapse at about 11.01a.m. Wednesday.
TCN said that the total system collapse of the grid was as a result of voltage collapse in some parts of the grid.
Ms Mbah said that the Kainji-Birnin Kebbi line "tripped on fault but was restored".
She also said "the TCN substations feed 132kV substations, through which Distribution Companies offtake electricity they deliver to electricity consumers nationwide".
