Following the nationwide power outage witnessed on Wednesday, July 20,2022, as a result of 7th national grid collapse in 2022, the system has begun a major recovery process.
EnergyDay’s check showed that TCN at at 8am on Thursday transmitted 3,098MegaWatts of electricity out of a total 3,967.10 MW generated on Thursday, July 21,2022.
As as the period of filling this report on Thursday, the eleven(11) electricity distribution companies (DISCOs) received about a total of 3,098.00MW of electricity, as Ikeja Disco received 443MW being the highest load allocation, followed by Abuja DisCo and Ibadan Disco that received 421MW and 378MW respectively.
Yola Disco received 89MW being the lowest energy allocated for the period under review.
The allocations to other DisCos were EKO DisCo (293MW), Jos DisCo (180MW), Enugu DisCo (300MW), Kano DisCo (222MW), Port Harcourt DisCo (226MW), Kaduna DisCo(209MW) and Benin DisCo (257MW).
This was confirmed in different statement released by most of the DisCos.
Meanwhile, the TCN in a statement released by Ndidi Mbah, TCN’s General Manager (Public Affairs) on the backdrop of the system collapse, confirmed that the national grid experienced system disturbance at about 11.27am on Wednesday July 2022.
The incident, according to the TCN’s spokesperson, was a result of sudden drop in system frequency from 49.94Hz to 47.36Hz, which created system instability.
Mbah said, “Based on reports obtained from the National Control Centre (NCC), it was precipitated by the tripping of a Unit (with a load of 106 MW) in one of the generating stations due to “Exhaust over Temperature”.
“This unwholesome event, which pulled out other grid-connected Units in the plant, resulted in aggregated generation loss of 457MW. In its wake, a train of events ensued – culminating in the collapse of the national grid.
“As obtainable in all systems, when a component of the electric power system is defective, the entire configuration is vitiated. However, inspite of setbacks encountered at the initial stage, grid restoration had almost been completed as at 11:00pm when this report was filed, ” Mbah said.
TCN however restated its commitment to leveraging the interventions instituted by the Federal Government to enhance power supply reliability so that the issue of system collapse will become a thing of the past.
Mbah noted that a full-scale investigation is being conducted to establish the cause of this failure.
