The Transmission Company of Nigeria (TCN) has dispelled reports of a national grid collapse, explaining that the grid merely experienced a transmission line tripping on Saturday, January 11, 2025. This clarification comes amidst widespread power outages in parts of the country, leading to speculation of a grid failure.
In a statement issued by TCN spokesperson Ndidi Mbah, the company confirmed that the tripping occurred at approximately 1:41 p.m., affecting electricity supply to the Lagos axis. According to Mbah, the incident involved the Benin-Omotosho 330kV transmission line, which tripped alongside the Osogbo-Ihovbor line earlier in the day.
“The Transmission Company of Nigeria, TCN, hereby states that the nation’s grid did not experience a collapse today,” the statement read. “At about 1:41 p.m., the Osogbo-Ihovbor line tripped, followed by the Benin-Omotosho line. This incident impacted bulk electricity supply to Lagos but did not result in a system collapse.”
Before the incident, power generation on the grid stood at 4,335.63 megawatts. After the tripping, generation dropped to 2,573.23 megawatts, confirming a partial disruption rather than a total collapse, TCN stated.
The affected lines impacted several power stations, including Egbin, Olorunsogo, Omotosho, Geregu, and Paras. While most of these stations have been restored, efforts are ongoing to bring the Benin-Omotosho line back online.
Power outages and instability in the national grid have been a recurring issue. Reports indicate that the grid experienced at least 12 collapses in 2024, highlighting ongoing challenges in Nigeria’s electricity sector, including transmission line failures and vandalism.
This latest clarification by TCN aims to allay fears of another grid collapse while underscoring the need for continued investment in grid stability and infrastructure to prevent future disruptions.
