The Transmission Company of Nigeria (TCN) has revealed what caused the total system collapse that caused total blackout for Nigerians.
Revealing the cause to NAN on Thursday, TCN’s General Manager, Mrs Ndidi Mbah, 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 added that the TCNs 330kV substations feed 132kV substations, through which Distribution Companies offtake electricity they deliver to electricity consumers nationwide.
NatureNews recalls that there was national grid collapse at about 11.01am Wednesday.
However, TCN has restored bulk power to all the 330 Kilo Volt (kV)Transmission Stations across the entire grid.
