TCN confirms restoration of National Grid, says recent explosion was due to transformer explosion at Jebba substation

The Transmission Company of Nigeria (TCN) says the national grid that collapsed at about 8.15am on Saturday October 19, has been restored. 

According to a statement released, TCN blamed the recent collapse on an explosion at the bus section of a current transformer at the 330-kilovolt (kV) Jebba transmission substation, Niger state.

In the statement signed by its General Manager Public Affairs, Ndidi Mbah, TCN said following the explosion that occurred, the commission activated a protection system, which promptly opened the busbars to curtail the explosion.

“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

The system failure earlier today was the third time in a week and the eighth time in 2024.
