The Nigerian Independent System Operator (NISO) has reported a significant reduction in electricity supply nationwide, citing insufficient gas supplies to thermal power plants and lowered water levels at hydroelectric stations as the primary factors behind the shortfall.
The operator explained that these issues have hampered the capacity of thermal generating stations, which in turn has led to decreased power allocations to electricity distribution companies (DisCos) and increased load shedding. As a result, many consumers are experiencing fewer hours of electricity availability.
In a statement released on November 5, 2026, NISO indicated that limited gas supplies are preventing thermal plants from operating effectively, while the diminished water inflows affecting reservoirs have further impacted hydroelectric generation capability.
The organization acknowledged the hardships this decline in supply has caused for consumers and reassured the public that efforts are underway to stabilize the grid and enhance the distribution of available electricity. NISO emphasized its commitment to diversifying the country’s energy mix and ensuring the reliable operation of the national power grid despite existing constraints.
The ongoing electricity shortages reflect a broader trend that has been troubling Nigerians for some time. In March 2026, Ikeja Electric pointed to inadequate gas deliveries as a contributing factor to escalating power outages in Lagos. Additionally, the Ministry of Power apologized earlier this year for widespread outages, linking the generation shortfall to gas supply issues and suggesting increased investment in renewable energy to lessen reliance on gas-fired power plants.
