Nigeria was thrown into darkness on Friday after the national electricity grid suffered a total collapse, cutting power supply across large parts of the country in what has been confirmed as the first grid failure of 2026.
Data obtained from the Nigerian Independent System Operator (NISO) showed that electricity generation dropped to zero megawatts, while power supply to all 11 electricity distribution companies crashed completely at about 1:00 p.m.
All 11 DisCos Hit as Power Supply Drops to Zero
According to system figures, the following distribution companies recorded zero load allocation during the collapse:
- Benin DisCo
- Eko DisCo
- Enugu DisCo
- Ikeja DisCo
- Jos DisCo
- Kaduna DisCo
- Kano DisCo
- Port Harcourt DisCo
- Ibadan DisCo
- Abuja DisCo
- Yola DisCo
The sudden outage immediately triggered blackouts across homes, offices, businesses and industrial areas nationwide.
Another Grid Failure After a Troubled 2025
The latest collapse adds to Nigeria’s long list of power system failures, coming just months after multiple grid breakdowns in 2025, with the most recent incident recorded on December 29, 2025.
Despite repeated assurances and reforms in the power sector, grid instability has remained a persistent problem, raising concerns about the reliability of electricity supply in Africa’s most populous country.
Recent Efforts to Stabilise the Grid
Ironically, the blackout occurred shortly after some positive developments in the power sector:
- The Niger Delta Power Holding Company (NDPHC) recently announced the restoration of an additional 450 megawatts to the national grid following maintenance work at the Geregu National Integrated Power Project.
- In another effort to improve grid stability, NISO revealed that on November 9, 2025, Nigeria carried out a synchronisation test with the West African Power Pool (WAPP), linking the national grid with the broader West African electricity network.
These moves were expected to strengthen system resilience, making Friday’s total collapse particularly alarming.
Growing Concerns Over Power Infrastructure
Power sector analysts warn that repeated grid collapses point to deeper structural and technical weaknesses, including aging infrastructure, inadequate spinning reserves, gas supply constraints and poor system coordination.
For many Nigerians, the blackout has once again highlighted the fragile state of the country’s electricity supply, despite billions invested in reforms and generation capacity over the years.
