NNPC Limited has announced a scheduled maintenance window on critical gas production assets operated by its joint venture partner, Seplat Energy Plc, a key supplier into the national gas transmission system.
According to a notice published by the company, the routine maintenance exercise will take place from February 12 to 15, 2026, temporarily reducing gas volumes delivered into the pipeline network managed by NNPC Gas Infrastructure Company Limited.
It described the intervention as a standard industry practice aimed at maintaining asset integrity, operational safety and long-term reliability of gas infrastructure. Periodic shutdowns of this nature are designed to sustain performance efficiency and minimise the risk of unexpected outages across the supply chain.
Power Generation Impact Expected to Be Limited
NNPC indicated that the temporary reduction in gas supply may affect some power generation companies dependent on feedstock from the NGIC network, potentially leading to a modest decline in electricity output during the maintenance window.
However, the company emphasised that mitigation measures are already in place. NNPC Gas Marketing Limited is actively engaging alternative gas suppliers to stabilise supply and cushion downstream disruptions.
Energy analysts note that while short-term supply adjustments are typical during planned maintenance cycles, the effectiveness of contingency sourcing will determine the extent of any impact on Nigeria’s power generation profile.
Coordination to Ensure Rapid Restoration
NNPC and Seplat confirmed close operational coordination to ensure the maintenance is executed safely and completed within schedule. Full gas supply into the NGIC network is expected to resume immediately after the exercise, enabling affected power plants to return to normal operations.
The maintenance programme reflects a broader industry emphasis on preventive asset management amid rising domestic gas demand and expanding gas-to-power infrastructure.
Energy Desk Perspective
Routine maintenance of upstream and midstream gas assets is increasingly critical as Nigeria deepens reliance on natural gas for power generation and industrial supply. While temporary output reductions can tighten system margins, proactive maintenance typically enhances long-term network reliability and reduces systemic risk.
The episode underscores the structural sensitivity of Nigeria’s electricity supply chain to upstream gas availability — a dynamic that continues to shape operational planning across the energy sector.
NNPC said further updates will be issued as necessary.
