NISO cites gas shortages for Nigeria's recent power outages

The Nigerian Independent System Operator (NISO) has reported that recent power blackouts across Nigeria are due to gas supply constraints impacting thermal power plants and reduced water inflows affecting hydroelectric power stations. In a statement issued on November 5, 2026, NISO explained that limited gas availability has hindered thermal generating stations from operating at full capacity.

Additionally, decreased water inflows into reservoirs have further diminished the generation capacity of hydroelectric power stations. This decline in power generation has led to a reduction in electricity allocated to Distribution Companies (DisCos), resulting in shorter hours of electricity supply and increased load shedding.

The extent of the impact varies across the country based on available generation and allocations to individual DisCos. NISO acknowledged the concerns of consumers and stakeholders regarding the ongoing power generation shortfall and stated its commitment to diversifying the national grid's energy mix to enhance electricity supply security while maintaining grid stability.
