Declining electricity output linked to inadequate gas supply, says NISO

• The Nigerian Electricity System Operator disclosed that the declining power output stems from gas supply shortfalls and generation limitations
• The thermal plants, which drive Nigeria’s electricity generation, are operating below capacity due to inadequate gas supply
• The reduced generation has forced lower allocations to Distribution Companies, with load shedding used to stabilise the grid

The low power output currently experienced in the country has been attributed to generation shortfalls and gas supply limitations affecting thermal plants by the Nigerian Electricity System Operator.

In a statement issued on February 27, 2026, the operator explained that the average available generation of about 4.3 GW stems largely from inadequate gas supply, which directly limits the capacity of thermal plants, Nigeria’s primary source of electricity.

“Thermal plants account for the dominant share of Nigeria’s generation. Any limitation in gas supply directly reduces available generation capacity and overall grid output,” the statement noted.

According to the system operator, thermal stations require about 1.63 million standard cubic feet (MMSCF) of gas daily to function at optimal capacity. 

However, as of February 23, only 692,000 MMSCF of gas was supplied, less than 65% of the required volume, thereby constraining generation output.

The reduced generation has also affected electricity distribution, leading to lower energy allocations for Distribution Companies (Discos). 

In situations where generation drops significantly, load shedding measures are implemented to maintain grid stability and prevent disturbances.

The operator assured stakeholders that efforts are ongoing to improve gas supply and restore generation capacity. 

“We regret the inconvenience this situation may cause electricity consumers and market participants, and remain committed to optimising available energy as gas supply improves,” NISO stated.

Energy sector analysts note that Nigeria’s heavy dependence on gas-powered plants makes electricity generation vulnerable to fuel supply disruptions. 

Initiatives to enhance gas infrastructure and diversify energy sources are expected to contribute to long-term grid stability and improved power availability.
