The Nigerian Independent System Operator, NISO, has attributed declining power output in the country to generation shortfalls and gas supply limitations.
NISO made this disclosure in a statement on Friday, saying that any disruption or limitation in gas supply directly affects available generation capacity and overall grid output.
It revealed that the current energy allocated to Distribution Companies, DisCos, reflects the reduced supply available on the grid.
According to NISO, available operational data indicates that thermal power plants collectively require an estimated 1,629.75 million standard cubic feet (MMSCF) of gas per day to operate at optimal capacity.
NISO maintained that actual gas supply to the stations as of February 23, 2026, stood at approximately 692.00 MMSCF, representing a significant shortfall in daily gas supply requirements.
It stressed that the available gas supply represents less than 43% of the required volume, resulting in constrained generation output, and emphasised that the current low generation level is fundamentally driven by inadequate gas supply to thermal generating units, leading to reduced energy allocation to the DisCos.
“We hereby notify the general public and all market participants that the current average available generation of approximately 4,300MW is primarily due to inadequate gas supply to thermal generating stations.
“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.
“While we regret the inconvenience this situation may cause electricity consumers and affected market participants, we will continue to work closely with relevant stakeholders to ensure full energy allocation as soon as gas supply improves and generation capacity is restored,” NISO said in the statement.
