Grid collapse to protect appliances of Nigerians – TCN
Prior to today’s national grid collapse, the Transmission Company of Nigeria (TCN) had explained that the frequency at which the national grid operates needs not significantly deviate from a range, else it will be extremely detrimental to electrical equipments and appliances.
In a post via X (formerly Twitter), the agency disclosed that the Nigerian national grid system is set at a frequency of 50Hz and that whenever there is a significant rise, the grid’s self trip mechanism is triggered.
The post titled “Info” national grid collapse simplified” reads: “GenCos generate electricity in a measured quantity MW (megawatts). The generated electricity is transmitted by TCN to DisCos in kV(kilovolts). DisCos distribute the power to end users.
“These 3 steps are considered a cycle , the rate at which these happen repeatedly is technically called a Frequency measured in Hz(hertz) The Nigerian national Grid is set at a frequency of 50Hz.
“This frequency needs to not significantly deviate from this range, else it will be extremely detrimental to electrical equipments and appliances.
“Therefore, when there is a significant fault from generation,transmission or distribution; a SELF TRIP mechanism is triggered by the Grid system. This is known as Grid collapse.
“Grid Disturbances are classified as when the resetting of the Grid system is done preemptively by system operators to forestall an impending issue which could lead to a catastrophic grid collapse”.

NERC to hold public hearing on incessant grid collapses
The Nigerian Electricity Regulatory Commission (NERC), on Saturday announced its plans to conduct a public investigation into the incessant grid collapses that have led to widespread power outages across the country.
NERC’s decision follows the latest grid collapse which marked the third incident in one week.
Expressing concern, NERC in a statement posted on its official X handle noted that the disturbances threaten to reverse recent advancements in grid stability and infrastructure improvements.
It stated that while efforts to restore electricity have made significant progress, power was largely restored by 1 PM in 33 states and the Federal Capital Territory.
“In line with the provisions of the Electricity Act 2023, NERC is in the process of unbundling the System Operator function from the Transmission Company of Nigeria Plc. This move aims to foster better grid management and attract optimized investments in infrastructure.
“The forthcoming public hearing will seek to uncover both immediate and underlying causes of the recurring grid disturbances. Details regarding the date and venue of the hearing will be published soon in national dailies, and all stakeholders are encouraged to participate in this critical dialogue”, NERC stated.
Meanwhile, the Transmission Company of Nigeria (TCN) in a statement issued by its General Manager, Public Affairs, Ndidi Mbah, said that the latest grid disturbance was caused by the explosion at Jebba Transmission Station.
TCN said, “The Transmission Company of Nigeria hereby states that the national grid experienced a temporary disturbance at about 8:15 am, 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 the 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.”
