TCN urged the public to disregard unofficial reports and affirmed that only authorized sources can provide updates on the national grid’s status
The Transmission Company of Nigeria (TCN) has dismissed reports of a national grid collapse, stating that no system failure has occurred in 2025.
In a statement posted on X (formerly Twitter) on Saturday, TCN described the circulating claims of two grid collapses this year as “false and mischievous.”
“The Transmission Company of Nigeria hereby notes that the report making the rounds about the occurrence of two National Grid Collapses within the year 2025 is misleading and mischievous,” the statement read.
“We appeal to the public to disregard this and other inaccurate reports on the national grid (including past records) from unauthorized sources.”
TCN emphasized that only the National Control Centre System Operator or its designated backup, the National Supplementary Control Centre (SNCC), has the authority to provide official updates on the grid’s status.
Clarifying the recent power disruption, the company acknowledged a case of line tripping on the Omotosho-Ikeja West 330kV transmission line. Additionally, the Benin-Egbin 330kV line was undergoing a scheduled outage for mechanical line tracing.
“The tripping resulted in a cascaded outage, affecting electricity supply in Abuja, Lagos, and Osogbo. However, power has since been fully restored to these areas,” TCN stated.
The company reiterated that the national grid remained stable and urged the public to rely on official sources for accurate information.
Despite TCN’s assurances, parts of the country experienced power outages on Wednesday due to a disturbance in the national grid.
According to data from the Independent System Operator (ISO), the average electricity supply on the grid dropped from 4,064.70 megawatts (MW) at 11 a.m. to 1,222.78 MW by noon.
TCN has assured that efforts are ongoing to ensure grid stability and prevent future disruptions.
