The Nigerian Independent System Operator (NISO) says the continued decline in power generation is due to persistent gas supply challenges affecting several thermal power plants.
On February 27, NISO had reported a reduced energy
allocation to electricity distribution companies (DisCos) due to inadequate gas
supply to thermal generating stations.
In a statement, the NISO said the ongoing issue led to a
drop of about 292 MW in available grid generation on Thursday.
“The Nigerian Independent System Operator (NISO) wishes to
inform stakeholders and the public of the continued decline in electricity
generation on the national grid arising from persistent gas supply constraints
affecting several thermal power plants,” the statement reads.
“As at 05:00 hours of today Thursday, 5th March 2026, total
generation on the national grid stood at 3,940.53 MW, which was already below
the expected capacity due to existing gas supply limitations impacting a number
of generating stations.
“Between 06:00 hours and 08:00 hours, several generating
units were forced to shut down as a result of inadequate gas supply to the
plants.”
The system operator said this resulted in a cumulative
reduction “of approximately 292 MW in available generation on the grid during
the period”.
According to the statement, 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 run at optimal capacity.
“However, actual gas supply to these stations was
approximately 652.92MMSCF, representing about 40% of the gas required for
optimal generation,” NISO said.
“These developments further reduced the total generation
available for dispatch to the national grid and have contributed to the current
generation inadequacy being experienced across the system.
“NISO is actively working with the affected Generation Companies (GenCos) and relevant gas suppliers to closely monitor the situation and facilitate the restoration of generation as soon as gas supply to the affected plants stabilises.”
The system operator said it is taking necessary operational
measures to maintain grid stability while managing the impact of the reduced
generation on the network.
The NISO said it remains committed to keeping stakeholders
and the public informed on developments affecting the national grid.
