Nigeria’s Federal Ministry of Power linked electricity interruptions in five locations to constrained gas and hydropower generation and maintenance problems, following a period of improved service in the affected areas.
The ministry named Lagos, Abuja, Ogun, Kwara and Oyo. It said gas supply constraints at thermal power stations and lower water inflows into reservoirs had reduced generation from gas and hydroelectric plants. Maintenance and operational problems in parts of the electricity system also contributed to the disruptions.
The ministry said its initial assessment found no major or systemic grid failure behind the interruptions. It said the supply decline reflected a combination of lower generation and operational issues, which authorities were working to address.
The affected areas had recently seen more consistent electricity service before the latest drop, according to the ministry. It acknowledged that the interruptions were affecting households, businesses and public institutions.
The ministry said Minister of Power Joseph Tegbe is coordinating restoration efforts with distribution companies and the two grid bodies, the Transmission Company of Nigeria (TCN) and the Nigerian Independent System Operator (NISO). Discussions with the operators are focused on resolving operating constraints, advancing maintenance work already underway and keeping the public informed.
The disruptions follow NISO’s earlier account of the generation decline. The operator said gas shortages and reduced reservoir inflows had limited output and cut electricity allocations to distribution companies, or DisCos. It reported that some customers were receiving less service and facing additional load shedding, with effects varying by region according to generation and each distributor’s allocation.
The ministry said it would provide further updates as restoration work progresses.
