Power Supply May Dip Temporarily as Seplat Conducts Gas Maintenance – NNPC
Electricity generation in Nigeria is set to experience a temporary dip as Seplat Energy Plc undertakes scheduled maintenance on key gas production facilities, the Nigerian National Petroleum Company Limited (NNPC Ltd) has announced.
The maintenance, running from February 12 to 15, 2026, is part of routine safety and asset integrity checks on Seplat’s facilities, which supply gas to several thermal power plants via the NNPC Gas Infrastructure Company Limited (NGIC) pipeline network.
NNPC’s Chief Corporate Communications Officer, Andy Odeh, stated that while the exercise is essential for ensuring long-term reliability, “some power generation companies reliant on this supply may experience reduced gas availability, which could modestly impact electricity generation levels within the timeframe.”
To mitigate disruptions, NNPC Gas Marketing Limited (NGML) is coordinating with alternative suppliers to maintain network stability. Full gas supply is expected to resume from February 16, 2026.
The Nigerian Independent System Operator (NISO) confirmed receipt of the notification and warned that major thermal plants, including Egbin, Azura, Sapele, and Transcorp, may be directly affected, while others such as NDPHC Sapele, Olorunsogo, and Omotosho could face indirect impacts due to network balancing.
NISO emphasized that any potential load shedding will be structured, transparent, and coordinated with Distribution Companies (DisCos), prioritizing critical national infrastructure, essential services, and security installations.
During the maintenance, the National Control Centre will enhance monitoring and contingency planning to preserve grid stability. Both NNPC and NISO appealed to the public for understanding, highlighting that the exercise is crucial for the long-term safety, reliability, and sustainability of Nigeria’s gas infrastructure supporting power generation.
