Nigeria’s electricity generation is expected to weaken temporarily this week as routine maintenance at a key gas facility reduces fuel supply to several major power stations, officials have warned.
The Nigerian National Petroleum Company Limited (NNPC Ltd) announced that Seplat Energy Plc, a joint-venture partner and significant supplier of natural gas into the national pipeline system, will carry out scheduled maintenance on its gas production infrastructure from 12 to 15 February 2026.
According to a statement by NNPC’s communications team, the four-day exercise part of standard safety and asset integrity protocols will temporarily reduce gas deliveries into the NGIC pipeline network, which feeds fuel to several thermal power plants connected to the national grid.
As a result, some generation companies that depend on the facility’s gas supplies are likely to face lower fuel availability during the maintenance period, potentially reducing overall electricity output nationwide.
The Nigerian Independent System Operator (NISO) confirmed it received formal notice of the planned shutdown and has warned of associated gas supply constraints affecting thermal plants such as Egbin, Azura, Sapele and Transcorp Power Stations, while others may face indirect effects due to wider network balancing challenges.
NISO said the national grid will be closely monitored throughout the maintenance window to safeguard system stability, and any load management including structured shedding, if necessary would be organised with distribution companies, prioritising power to essential services and critical infrastructure.
NNPC said it is working with Seplat and alternative suppliers to bridge any anticipated shortfalls and help maintain stability, with full gas flows expected to resume on 16 February 2026 following the completion of maintenance work.
