Poor power supply: NISO heaps blame on gas companies 

From Isaac Anumihe, Abuja

Following the consistent low supply of electricity to the country, Nigerian Independent System Operator (NISO) has heaped the blame on the gas companies, saying that the generation companies generate approximately 4,300MW due to inadequate gas supply to them. 

NISO said that the thermal plants account for the dominant share of Nigeria’s generation mix and so any disruption or limitation in gas supply directly affects available generation capacity and overall grid output.

To this effect, NISO, noted, the current energy allocated to Distribution Companies (DisCos) reflects the reduced supply available on the grid.

“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. However, as of February 23, 2026, actual gas supply to the stations stood at approximately 692.00 MMSCF, representing a significant shortfall in daily gas supply requirements.
“The available gas supply represents less than 43 per cent of the required volume, resulting in constrained generation output. The current low generation level is fundamentally driven by inadequate gas supply to thermal generating units, leading to reduced energy allocation to the DisCos” the operator, said.

In a statement, the management of NISO, also explained that when total system generation drops significantly, NISO must implement load shedding across the system, while dispatching available energy in line with the Nigerian Electricity Regulatory Commission (NERC) MYTO (multi year tariff order) 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” it assured.
