Nigeria’s power grid experienced a partial collapse on Tuesday, marking the ninth such incident this year.
The Transmission Company of Nigeria (TCN) attributed the outage to a disturbance that destabilized the system.
While some areas, including the capital Abuja, recovered power within an hour, other regions remained without electricity.
TCN engineers are working to restore power to affected areas.
Frequent blackouts are a persistent problem in Nigeria, largely due to aging infrastructure, vandalism, and insufficient gas supply for thermal power plants.
Despite having the capacity to generate over 13,000 megawatts of power, the grid can only distribute a fraction of this amount, forcing many to rely on costly generators.
