The Transmission Company of Nigeria (TCN) has announced that the national grid, which collapsed at approximately 8:15 AM on Saturday, 19 October, has been successfully restored.
In a statement, TCN attributed the grid failure to an explosion in the bus section of a current transformer at the 330-kilovolt (kV) Jebba transmission substation in Niger State.
TCN’s General Manager of Public Affairs, Ndidi Mbah, explained that following the explosion, a protection system was activated, promptly opening the busbars to mitigate the impact of the incident.
“The Transmission Company of Nigeria hereby states that the national grid experienced a temporary disturbance at about 8:15am, today, 19th Oct. 2024.
“According to the report from the NCC, the bus section of a current transformer exploded at 330kV Jebba Transmission Substation and as expected, the protection system was activated, and this promptly opened the busbars to curtail the explosion, thereby preventing outbreak of fire and further damage to adjacent equipment.
“The action of the protection system led to a temporary disturbance on the grid. Our engineers at Jebba have successfully carried out switchings, isolating the faulty current transformer. They have equally reconfigured the busbar arrangement, restoring power supply to the station, and other parts of the grid.” the statement read.
This incident marks the third system failure in a week and the eighth occurrence in 2024.
