The Nigerian Independent System Operator (NISO) has raised concerns over the consistent low supply of gas to electricity generation companies, resulting in a total generation of 3,940.53 megawatts (MW), below the expected capacity.
According to NISO, between 06:00 and 08:00 hours on March 4, 2026, several generating units were forced to shut down due to insufficient gas supply, leading to a cumulative reduction of approximately 292 MW in available generation on the national grid during the period.
“Operational data as of March 4, 2026, indicate that thermal power plants require approximately 1,588.61 million standard cubic feet (MMSCF) of gas per day to operate at optimal capacity. However, actual gas supply to these stations was approximately 652.92 MMSCF, representing about 40 per cent of the gas required for optimal generation,” NISO stated.
The shortfall in gas supply has further reduced the total electricity available for dispatch, contributing to the current generation inadequacy being experienced across the system.
NISO assured that it is actively engaging with the affected generation companies (GenCos) and relevant gas suppliers to monitor the situation closely and facilitate the restoration of electricity generation once gas supply stabilises.
“The system operator continues to take necessary operational measures to maintain grid stability while managing the impact of the reduced generation on the network. NISO remains committed to keeping stakeholders and the public informed on developments affecting the national grid,” the agency added.
