The Nigerian National Petroleum Company Limited (NNPC Ltd) has announced that gas supply to some power generation companies will decline temporarily from February 12 to February 15, 2026, due to scheduled maintenance by its joint venture partner, Seplat Energy Plc.
The disclosure was contained in a statement issued on Thursday by NNPC Ltd’s Chief Corporate Communications Officer, Andy Odeh, titled “Notice of Scheduled Maintenance on Major Gas Plant and Facilities.”
According to the company, the four-day shutdown of Seplat’s gas production facilities is expected to moderately affect gas deliveries to some power generation companies, with a limited impact on electricity output nationwide.
NNPC Ltd said Seplat Energy Plc will carry out routine and mandatory maintenance on its gas production facilities in line with industry safety standards. The company explained that the exercise is part of operational protocols designed to safeguard critical infrastructure and ensure long-term reliability.
NNPC added that normal gas flows are expected to resume promptly once the maintenance is concluded, allowing affected power plants to return to full operations.
Nigeria’s electricity sector depends largely on gas-fired thermal power plants, which account for more than 70 percent of installed generation capacity.
Most grid-connected plants rely on a steady gas supply from upstream producers in the Niger Delta, transported through NGIC and related pipeline infrastructure to major generation clusters.
Gas supply disruptions in the past have resulted from technical faults, pipeline vandalism, and commercial disputes.
Such interruptions have often led to generation shortfalls and grid instability.
Even minor reductions in gas volumes can compel system operators to scale back output and adjust load distribution across the country.
These recurring vulnerabilities highlight the critical link between upstream gas operations and downstream electricity generation, making maintenance windows closely watched events in the power sector.
Seplat Energy is a key supplier of gas into the NNPC Gas Infrastructure Company Limited pipeline network, which serves multiple thermal power plants and major industrial users nationwide. Its production volumes contribute significantly to gas availability within the national grid system.
Recently, the NNPC Ltd unveiled its Gas Master Plan 2026, targeting 10 billion cubic feet of daily gas production to drive industrialisation and strengthen Nigeria’s energy security.
