The Nigerian Independent System Operator (NISO) has attributed the current decline in electricity generation across the country to inadequate gas supply to thermal power stations and reduced output from hydroelectric plants.
The operator said in a statement signed by it's Management on Thursday that the constraints had reduced the volume of electricity available on the national grid, affecting allocations to electricity Distribution Companies (DisCos) and resulting in fewer hours of power supply to consumers.
NISO disclosed this in a statement issued on Thursday, November 5, 2026, explaining that limited gas availability had prevented some thermal power stations from operating at their available capacities.
It added that reduced water inflows into reservoirs had also affected the generation capacity of hydroelectric power stations.
According to the operator, the combined effect of these challenges had led to increased load shedding across distribution networks, with the level of disruption varying among DisCos depending on available generation and their respective allocations.
NISO acknowledged the impact of the generation shortfall on electricity consumers nationwide, expressing appreciation for the concerns raised by members of the public and other stakeholders.
The operator assured Nigerians of its commitment to maintaining grid stability, optimising the dispatch of available electricity and ensuring the secure, reliable and efficient operation of the national grid despite prevailing operational challenges.
It also disclosed that efforts were ongoing to diversify the country's energy mix to strengthen energy security and ensure more reliable electricity supply.
