Nigeria has been plunged into another nationwide blackout following the collapse of the national electricity grid on Tuesday.
Real-time data from the Nigerian Independent System Operator (NISO) showed that power allocation to all 11 electricity distribution companies (DisCos) dropped to zero megawatts as of 11:00 am.
This incident marks the second grid collapse in less than a week, coming just days after a similar failure recorded on Friday, January 23, 2026, which was the first grid collapse of the year.
Electricity supply to all DisCos; including Benin, Eko, Enugu, Ikeja, Jos, Kaduna, Kano, Port Harcourt, Ibadan, Abuja, and Yola was affected, leaving millions of homes and businesses across the country without power.
The national grid has continued to experience repeated system failures despite government assurances and investments aimed at improving electricity transmission and stability.
The latest collapse has renewed concerns over the reliability of Nigeria’s power infrastructure, especially as it comes shortly after a December 2025 grid failure.
Recently, the Niger Delta Power Holding Company (NDPHC) announced the restoration of an additional 450 megawatts to the grid after maintenance work at the Geregu National Integrated Power Project (NIPP) plant.
The upgrade was expected to improve grid stability and reduce frequent collapses, but the latest development suggests the impact may have been limited or short-lived.
