Nearly 20 percent drop expected as key thermal plants face gas constraints, load shedding likely until February 16….
Nigeria’s electricity generation is projected to decline over the next four days following a scheduled maintenance shutdown at a major gas supply facility, a development expected to cut power output by 934.96 megawatts.
The anticipated reduction represents about 19.67 percent of the current available generation capacity of 4,753.10 megawatts, heightening concerns over possible nationwide load shedding during the period.
The Nigerian Independent System Operator disclosed this in a statement issued Thursday titled “Anticipated Gas Supply Constraints and Potential Load Management Measures.”
According to the system operator, the maintenance exercise, scheduled to run from February 12 through February 15, 2026, will temporarily limit gas supply to several thermal power stations, significantly affecting electricity generation across the national grid.
NISO explained that the situation followed a formal notice of the planned shutdown of a major gas facility and assured that full gas supply is expected to be restored on February 16, 2026.
During the maintenance window, gas availability to some generating plants will be reduced, directly affecting major stations including Egbin, Azura, Sapele and Transcorp power plants.
Other stations such as NDPHC Sapele, Olorunsogo and Omotosho are also likely to experience indirect constraints due to broader network gas balancing challenges.
The operator warned that the shortfall in generation could lead to structured load shedding across the country, with electricity distribution expected to prioritize critical infrastructure and essential services.
Normal gas supply and improved power generation are expected to resume once the maintenance is completed on February 16, 2026.
