Nigeria’s national electricity grid suffered another collapse on Tuesday morning, January 27, 2026, plunging large parts of the country into darkness and marking the second major system failure recorded this month.
Data from the Nigerian Independent System Operator (NISO) showed that electricity generation and load allocation to all eleven distribution companies fell to zero megawatts by about 11:00 a.m., triggering a nationwide outage. Cities and regions across the country, including major urban centres, experienced the blackout as a result.
The collapse follows an earlier grid failure on January 23, 2026, itself the first system collapse of the year, which also caused widespread power outages. Reports indicate that grid instability has been a recurring issue, with similar breakdowns occurring as recently as late 2025.
Preliminary observations by grid operators suggest that the failure may be linked to technical problems within the transmission network, including the tripping of high-voltage lines and the disconnection of generating units, factors previously cited in official analyses of grid disturbances. Efforts to stabilise the system and restore power are underway, but a comprehensive statement from the Transmission Company of Nigeria (TCN) had not been released at the time of reporting.
This latest collapse exacerbates longstanding challenges in Nigeria’s power sector, where frequent outages and system failures have disrupted homes, businesses and public services for years. The government and power sector stakeholders have repeatedly acknowledged the issue, but solutions have so far delivered limited improvement in grid reliability.
Electricity consumers are advised to expect intermittent supply as restoration continues and engineers work to stabilise the interconnected grid
