Grid operator reports power slump on gas and water limits
Nigeria faces widespread blackouts as limited fuel deliveries and low reservoir levels constrain thermal and hydroelectric generation.
Key points
- The Nigerian Independent System Operator announced a drop in electricity generation on Thursday.
- Thermal plants faced tight gas availability while hydroelectric facilities struggled with low water inflows.
- Distribution companies received reduced allocations, leading to shorter supply hours and increased load shedding.
Electricity generation across Nigeria has dropped significantly, triggering blackouts and prompting increased load shedding by distribution companies. According to reports from BusinessDay, The Whistler Newspaper, and Nairametrics, the Nigerian Independent System Operator issued a statement attributing the nationwide supply deficits to twin pressures on the country's primary power sources.
What happened
The system operator explained that thermal generating stations were unable to operate at full capacity due to restricted gas supplies. At the same time, declining water inflows into reservoirs reduced the electricity output of hydroelectric facilities. This combined shortfall lowered the total volume of power available on the national grid. Consequently, electricity distribution companies received smaller allocations, forcing them to implement shorter supply hours and manage network loads through rotational outages.
The impact of these generation constraints varied across regions, depending on the specific volume allocated to each distribution network. Consumers and businesses in areas with lower allocations experienced prolonged blackouts, forcing many establishments to rely heavily on backup generators to maintain essential operations.
Why it matters
The latest grid slump underscores the vulnerability of Nigeria's electricity matrix, which relies predominantly on gas-fired thermal plants. According to World Bank figures from 2021, renewables accounted for 22 percent of the country's electricity output, leaving the system exposed when fuel deliveries or water levels fluctuate. With national electricity use standing at 140.6 kilowatt-hours per person in 2024—compared to a global average of 3,708.5 kilowatt-hours—unreliable grid supply exacerbates economic pressures. Enterprises and households that depend on auxiliary petrol or diesel generation face higher operational costs, highlighting the urgent need for a more secure and diversified energy mix to support broader economic development.
What comes next
The system operator stated that it is exploring options to diversify the energy sources feeding the national grid to enhance long-term security. Meanwhile, the agency indicated it will focus on maintaining overall network stability, optimising the dispatch of available power, and managing operations within existing constraints.
