The Nigerian Independent System Operator (NISO) has announced a troubling decline in the nation’s power generation, which has dropped to approximately 4,300 megawatts. This downturn is largely attributed to inadequate gas supply to thermal generating stations.
In a statement released today Friday, NISO emphasized that thermal plants comprise the majority of Nigeria’s generation mix. Consequently, any disruptions or limitations in gas supply directly impact the available generation capacity and overall grid efficiency. As a result, the energy currently allocated to Distribution Companies (DisCos) mirrors the decreased supply on the grid.
Operational data provided by NISO indicates that thermal power plants require an estimated 1,629.75 million standard cubic feet (MMSCF) of gas daily to function at optimal capacity. However, as of February 23, 2026, actual gas supply to these plants was recorded at approximately 692.00 MMSCF, revealing a significant shortfall in daily gas needs.
This limited gas supply amounts to less than 43% of the necessary volume for efficient operation, resulting in constrained generation output. NISO clearly stated that the primary cause of the current low generation levels is the inadequate gas supply to thermal units, which has led to reduced energy allocations for the DisCos.
While NISO expressed regret over the inconvenience caused to electricity consumers and market participants, the organization reiterated its commitment to collaborating with relevant stakeholders. The goal is to ensure full energy allocation is restored as soon as gas supply improves and generation capacity is increased.
“When total system generation drops significantly, the Independent System Operator must implement load shedding across the system, while dispatching available energy in line with the NERC MYTO allocation percentages across all distribution networks to maintain grid stability and prevent system disturbances,” NISO explained.
