KEY POINTS
- Nigeria’s national grid collapsed on Tuesday morning, dropping generation to zero megawatts and cutting power to all 11 DisCos.
- The incident marks the second grid collapse in five days, following a similar outage on January 24, 2026.
- Authorities are yet to explain the cause or provide details on restoration efforts, raising concerns over the sector’s stability.
Nigeria’s electricity sector suffered another major setback on Tuesday morning after the national power grid collapsed, triggering a widespread blackout across several parts of the country.
Operational data from the Nigerian Independent System Operator (NISO) revealed that electricity generation fell to zero megawatts (MW) as of 11:00 a.m., effectively cutting off power supply to all 11 electricity distribution companies (DisCos) nationwide.
The sudden drop in generatin left homes, critical infrastructure without electricity, worsening ongoing concerns about the fragility of the country’s power system.
Second Collapse Within One Week
This latest incident represents the second national grid collapse in less than five days.
According to reports that the grid had earlier suffered its first collapse of the year on Friday, January 24, 2026, raising fresh questions about the reliability and resilience of Nigeria’s electricity transmission network.
Repeated collapses within such a short period highlight persistent structural and operational challenges within the power sector, including ageing infrastructure, poor maintenance, and system imbalances.
Silence from Authorities on Cause
As of the time of filing this report, neither the Transmission Company of Nigeria (TCN) nor the Federal Ministry of Power had released an official statement explaining the cause of Tuesday’s system failure.
There was also no immediate information on restoration timelines or recovery measures being deployed to stabilise the grid and resume electricity supply.
Industry stakeholders and consumers alike are awaiting clarification on what triggered the collapse and what steps are being taken to prevent further occurrences.
