Plus the TCN’s account of what led to the collapse and how bulk power was restored to all the 330 Kilo Volt (kV)Transmission Stations across the entire grid.
The total collapse suffered by the Nigeria’s electricity tranmission system also known as national grid, which plunged the country into a blackout on Wednesday, lasted for 6 hours and 53 minutes.
Platforms Africa, which earlier broke the news of the collapse on Wednesday, May 12, 2021, gathered exclusively that the blackout lasted for just 7 minutes less than 7 hours. The leading pan-African newspaper has earlier reported that the grid failure occured at exactly 11: 01 am on Wednesday.
The total system collapse of the grid, which came barely three months after the February 9 collapse, was as a result of voltage collapse in some parts of the grid.
Confirming the report, the Transmission Company of Nigeria(TCN) maintained that it restored bulk power to all the 330 Kilo Volt (kV)Transmission Stations across the entire grid by 5.54pm Wednesday.
TCN’s General Manager, Mrs Ndidi Mbah, made this known in a statement in Abuja on Thursday sighted by Platforms Africa.
It would be recalled that there was national grid collapse at about 11.01am Wednesday.
TCN also confirmed 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 Compankes offtake electricity they deliver to electricity consumers nationwide.
