Nigeria’s electricity supply could face temporary pressure as NNPC announces that Seplat Energy Plc is scheduled to begin today, February 12, a four-day maintenance exercise at one of its major gas production facilities.
The maintenance, which will end on February 15, 2026, will lead to a temporary reduction in gas supply into the Nigerian National Petroleum Company (NNPC) Gas Infrastructure Company Limited (NGIC) pipeline network.
Seplat Energy is a joint venture partner of NNPC Ltd and a key gas supplier into the NGIC network,
According to a public notice issued by NNPC Ltd, some power generation companies that depend on gas from the affected facilities may experience reduced supply during the maintenance window, a development that could modestly impact electricity generation nationwide.
The statement further described the exercise as routine and necessary to ensure long-term operational safety and reliability.
Industry analysts note that Nigeria’s power sector remains heavily dependent on gas-fired plants, which account for the majority of grid-connected electricity generation. Temporary supply reductions, even when planned, can place pressure on an already fragile power system.
NNPC Ltd and Seplat Energy said they are coordinating closely to ensure the maintenance is completed within schedule and without safety incidents. In parallel, NNPC Gas Marketing Limited (NGML) is engaging alternative gas suppliers to reduce the impact of the shortfall and maintain network stability.
The companies expect full gas supply into the NGIC system to resume immediately after the maintenance is concluded, allowing affected power plants to return to normal output levels.
While routine maintenance is standard practice in the gas industry to prevent unplanned shutdowns, the episode highlights the tight linkage between Nigeria’s upstream gas infrastructure and electricity reliability, and the limited buffer capacity within the system.
The notice concluded by stating that as maintenance progresses, further updates will be provided.
