The Transmission Company of Nigeria (TCN) has restored bulk power to all the 330 Kilo Volt (kV)Transmission Stations across the entire grid by 5.54pm Wednesday.
TCN General Manager, Mrs Ndidi Mbah, made this known in a statement in Abuja on Thursday.
The national grid collapsed at about 11.01am Wednesday.
TCN said that the total system collapse of the grid was as a result of voltage collapse in some parts of the grid.
Mbah said that the Kainji – Birnin Kebbi line, however, tripped on fault but was restored.
She said that the TCNs 330kV substations feed 132kV substations, through which Distribution Companies off-take electricity they deliver to electricity consumers nationwide.
