Nigeria’s national electricity grid collapsed on Monday afternoon, plunging most parts of the country into darkness as power supply dropped to near zero, according to official distribution load figures.
Data released at 3:12 pm on December 29, 2025, showed that only two electricity distribution companies (DisCos) were receiving power at the time of the collapse. Ibadan Electricity Distribution Company (IBEDC) recorded a load of 30 megawatts (MW), while Abuja Electricity Distribution Company (AEDC) received 20 MW.
All other DisCos were allocated zero megawatts, signalling a widespread outage across the country.
DisCos affected include Benin, Eko, Enugu, Ikeja, Jos, Kaduna, Kano, Port Harcourt and Yola, all of which recorded 0 MW allocation, cutting off electricity supply to major cities, towns and industrial hubs.
In total, electricity distributed nationwide at the time stood at just 50 MW, far below normal operating levels and grossly inadequate to sustain power supply to households, businesses and critical infrastructure.
Nigeria’s power grid has suffered repeated system collapses in recent years, often resulting in nationwide blackouts and prolonged restoration efforts. Industry operators have frequently attributed the failures to a combination of technical faults, gas supply constraints and weak transmission infrastructure.
In a brief update, the Nigerian National Grid (NNG) said restoration efforts were ongoing.
However, as of the time of filing this report, no official statement had been issued by the Transmission Company of Nigeria (TCN) or the Federal Ministry of Power explaining the cause of the collapse or providing a clear timeline for the restoration of electricity supply.
The latest incident adds to growing concerns over the reliability of Nigeria’s power infrastructure amid rising demand and ongoing reforms in the electricity sector.
