There will likely be a brief decrease in electricity production throughout Nigeria when planned maintenance on a significant gas facility cuts off supply to a number of thermal power plants.
Seplat Energy Plc, a joint venture partner and important supplier to the NNPC Gas Infrastructure Company Limited (NGIC) pipeline network, will perform routine maintenance on its gas production facilities from February 12 to February 15, 2026, the Nigerian National Petroleum Company Limited (NNPC Ltd) announced Thursday.
The four-day exercise is a component of normal safety and asset integrity measures to guarantee the ongoing dependability and effectiveness of vital gas infrastructure, according to Andy Odeh, Chief Corporate Communications Officer at NNPC.
As a result, some power generation businesses that depend on this supply would have less gas available, which could have a little effect on the amount of energy generated in the future, the company said. In order to fill in expected gaps and preserve network stability, NNPC further stated that its subsidiary, NNPC Gas Marketing Limited (NGML), is enlisting the help of alternative suppliers. It is anticipated that the full gas supply will quickly return following the maintenance.
The Nigerian Independent System Operator (NISO), which confirmed the development, stated that it had been formally notified of the planned shutdown and issued a warning about possible gas supply shortages that could impact large thermal plants that are connected to the national grid.
Power plants including NDPHC Sapele, Olorunsogo, and Omotosho may be indirectly affected by network-wide gas balancing, while Egbin, Azura, Sapele, and Transcorp are likely to be directly affected.
Thermal generation capacity would decrease as a result of the short-term decrease in gas availability, according to NISO, underscoring the necessity of cautious system management to preserve grid stability. The operator further stated that any load shedding that would be required will be organized, open, and coordinated with Distribution Companies (DisCos), giving priority to security installations, vital services, and vital national infrastructure.
During the repair time, the National Control Center will step up its monitoring and emergency preparations. In order to guarantee the long-term safety, dependability, and sustainability of Nigeria’s gas infrastructure supporting the power sector, both NNPC and NISO made a plea for public understanding, highlighting the importance of the activity. On February 16, 2026, the full gas supply is anticipated to be restored.
