NNPC/Seplat Gas facility maintenance puts Nigeria in partial darkness

Seplat Energy Plc, a Joint Venture partner of NNPC Ltd and a key supplier of gas into the NNPC Gas Infrastructure Company Limited (NGIC) pipeline network, has commenced a scheduled routine maintenance on its gas production facilities from 12th to 15th February 2026.

The NNPC’s Chief Corporate Communications Officer, Andy Odeh said the planned activity forms part of standard industry safety and asset integrity protocols designed to ensure the continued reliability, efficiency, and safe operation of critical gas infrastructure.

Periodic maintenance of this nature is essential to sustain optimal system performance, strengthen operational resilience, and minimise the risk of unplanned outages.

It said during the four-day maintenance period, there will be a temporary reduction in gas supply into the NGIC pipeline network.

As a result, some power generation companies reliant on this supply may experience reduced gas availability, which could modestly impact electricity generation levels within the timeframe.

“NNPC Ltd and Seplat Energy are working closely to ensure that the maintenance is executed safely and completed as scheduled.

In parallel, NNPC Gas Marketing Limited (NGML) is engaging alternative gas suppliers to mitigate anticipated supply gaps and maintain stability across the network.”

It noted that upon completion of the maintenance exercise, full gas supply into the NGIC system is expected to resume promptly, enabling affected power generation companies to return to normal operations.

Meanwhile, the Nigerian Independent System Operator (NISO) said during the maintenance period, gas availability to certain power plants that depend on this supply network will be temporarily reduced.

Its power stations expected to be directly impacted include Egbin, Azura, Sapele, and Transcorp Power Plants, while NDPHC Sapele, Olorunsogo, and Omotosho Power Plants may experience indirect constraints due to network-wide gas balancing effects.

This will result in a temporary reduction in available thermal generation capacity across the national grid.

“This reduction underscores the need for careful system operation to maintain grid stability and reliability.”
