Several parts of Nigeria were plunged into darkness on Monday following the collapse of the national power grid, triggering widespread outages across the country.
The Nigerian Independent System Operator (NISO) confirmed the development in a statement issued on its official social media platforms on Monday, December 29, 2025.
Power supply drops sharply
According to NISO, electricity supply dropped drastically to 50 megawatts (MW) as restoration efforts commenced. The agency oversees power allocation to electricity distribution companies nationwide.
As of the time of filing this report, only Abuja and Ibadan were receiving electricity at the reduced level of 50MW. This marked a sharp fall from the 3,660MW allocated across the grid on Sunday, December 28.
Major DisCos record zero supply
Meanwhile, several electricity distribution companies recorded zero megawatts, highlighting the scale of the outage. Affected DisCos include Benin, Eko, Enugu, Ikeja, Jos, Kaduna, Kano, Port Harcourt, and Yola.
As a result, total electricity distributed nationwide stood at just 50MW, far below normal operating levels. The supply was insufficient to sustain households, businesses, and critical infrastructure.
Recurring grid failures raise concerns
Nigeria’s national grid has suffered repeated system collapses in recent years, often leading to nationwide blackouts and prolonged restoration periods.
Despite ongoing reforms, challenges persist within the power sector. A recent report by the Nigerian Electricity Regulatory Commission (NERC) pointed to unresolved structural and operational weaknesses in the grid.
Businesses and households hardest hit
Industry stakeholders say frequent grid collapses continue to hurt businesses, homes, and industrial clusters. They blame the situation on a mix of technical failures, management inefficiencies, and poor coordination across the power value chain.
For now, NISO says restoration efforts remain ongoing. However, there is no clear timeline for full recovery of power supply nationwide.
