Nigeria’s electricity supply is expected to decline over the next four days as scheduled maintenance on a major gas facility will reduce power generation by 934.96 megawatts.
The projected drop represents a 19.67 per cent reduction from the current available generation capacity of 4,753.10MW, raising concerns about possible load shedding nationwide.
The Nigerian Independent System Operator disclosed this in a statement on Thursday titled, “Anticipated Gas Supply Constraints and Potential Load Management Measures.”
According to NISO, the maintenance, scheduled from February 12 to February 15, 2026, will constrain gas supply to key thermal power plants, significantly affecting electricity generation across the national grid.
The system operator said, “The Nigerian Independent System Operator hereby informs the general public and all electricity market participants of anticipated gas supply constraints affecting some major thermal power generating stations connected to the national grid.
“This situation arises from a formal notification received on the scheduled maintenance shutdown of a major gas supply facility from 12 to 15 February 2026 (both days inclusive). Full gas supply is expected to be restored on 16 February 2026.”
NISO explained that during the maintenance period, gas availability to certain power plants will be temporarily reduced.
Power stations expected to be directly impacted include Egbin, Azura, Sapele and Transcorp power plants.
Others, such as NDPHC Sapele, Olorunsogo and Omotosho power plants, may also experience indirect constraints due to network-wide gas balancing effects.
The development could trigger structured load shedding across the country, with priority to be given to critical infrastructure and essential services.
Full gas supply is expected to resume on February 16, 2026.
