Normal supply of electricity may be disrupted in some parts of the country, as the Nigerian National Petroleum Company Limited announced that one of its Joint Venture partners, Seplat Energy Plc, has scheduled routine maintenance on its gas production facilities between February 12 and 15, 2026.
Consequently, the NNPC Ltd in a statement by its spokesperson, Andy Odeh, said supply of gas through a section of the NNPC Gas Infrastructure Company Limited (NGIC) pipeline network to some electricity generation companies may be affected.
During the four-day maintenance period, Odeh said there would be a temporary reduction in gas supply into the NGIC pipeline network.
“As a result, some power generation companies reliant on this supply may experience reduced gas availability, which could modestly impact electricity generation levels within the timeframe,” he said.
He however gave the assurance that the NNPC Ltd and Seplat Energy were working closely to ensure that the maintenance was executed safely and completed as scheduled.
In parallel, he said the NNPC Gas Marketing Limited (NGML) was engaging alternative gas suppliers to mitigate anticipated supply gaps and maintain stability across the network.
Upon completion of the maintenance exercise, full gas supply into the NGIC system, he said, is expected to resume promptly, enabling affected power generation companies to return to normal operations.
“This planned activity forms part of standard industry safety and asset integrity protocols designed to ensure the continued reliability, efficiency, and safe operation of critical gas infrastructure.
“Periodic maintenance of this nature is essential to sustain optimal system performance, strengthen operational resilience, and minimise the risk of unplanned outages,” Odeh explained.
Meanwhile, the Nigerian Independent System Operator (NISO) has announced that the power stations expected to be directly impacted by the disruption in gas supply include some major thermal power generating stations connected to the national grid, namely Egbin, Azura, Sapele, and Transcorp Power Plants, while the Niger Delta Power Holding Companies (NDPHCs) power plants in Sapele, Olorunsogo, and Omotosho may experience indirect constraints due to network-wide gas balancing effects.
In line with its statutory mandate, NISO said it would deploy appropriate real-time operational measures to safeguard the integrity and security of the national grid throughout the maintenance window.
The agency, which in charge of the management and operation of the power generation and distribution infrastructure in the country said any load shedding, if required, would be implemented in a structured, transparent, and equitable manner in close coordination with Distribution Companies (DisCos).
NISO said priority attention would be accorded to critical national infrastructure, essential services, and security installations.
While assuring all stakeholders and electricity consumers that every action taken during the scheduled maintenance period would be strictly guided by established operational procedures, grid security requirements, and reliability standards, NISO said the National Control Centre would intensify real-time system monitoring and contingency planning, while also ensuring fair load allocation based on available generation capacity.
Expressing appreciation to electricity consumers and all stakeholders for their understanding and cooperation as the gas supplier undertakes this essential maintenance, which it described as necessary to ensure the long-term safety, reliability, and sustainability of upstream gas infrastructure in support of Nigeria’s power sector.
NISO announced that full gas supply is expected to be restored on February 16, 2026.
