Gas Constraint: Conserve Energy, System Operator Urges As Power Restoration To Grid Continues

The Nigerian Independent System Operator (NISO) has called on consumers to conserve energy amid lingering gas constraints, even as power restoration progresses following repairs to vandalised infrastructure.

This comes after the Nigerian Gas Infrastructure Company (NGIC) fixed the critical Lagos-Escravos-Lagos gas line, boosting gas supply to key thermal plants and enabling gradual electricity ramp-up to the national grid.

The System Operator said a notable improvement in power generation following repair and restoration of the vandalised Lagos-Escravos-Lagos gas supply infrastructure by the Nigerian Gas Infrastructure Company (NGIC) has been recorded

It further said this has enhanced gas supply to several key thermal power plants across the country.

“This development is a positive step toward stabilising the electricity supply and improving grid reliability for consumers nationwide,” NISO noted.

Nigeria’s power sector has battled severe disruptions from vandalism on this vital pipeline, which feeds gas to major stations like Egbin, Sapele, and Afam.

Recent attacks slashed supplies, contributing to widespread blackouts, forcing plants offline and dropping average generation below 4,500MW.

NISO stated that NGIC’s timely restoration has revived flows, but NISO is proceeding cautiously to prevent grid instability, with standby plants awaiting gas confirmations by December 27, 2025.

“Currently, gradual power offtake is being carried out by the affected plants to ensure a smooth recovery and maintain the stability of both the gas supply network and the national electricity grid. This measured approach is aimed at preventing system stress and ensuring a reliable supply of electricity to meet the needs of industries, businesses, and households.

“Meanwhile, other thermal power plants remain available and on standby, awaiting confirmation of gas supply from their respective suppliers between now and Saturday, 27th December 2025. Once confirmed, these plants will be integrated into the national grid to further strengthen generation capacity and reduce the risk of outages,” it stated.

The operator urged energy conservation as efforts continue to bolster a resilient power system.

“NISO urges all consumers to continue practicing energy conservation where possible, as the coordinated efforts to stabilise power supply progress.

“NISO continues to work closely with relevant stakeholders, including power generation companies, gas suppliers, and regulatory bodies, to monitor developments and address any operational challenges in real time. The organisation remains committed to sustaining these improvements and ensuring a reliable, efficient, and resilient power system that supports Nigeria’s socio-economic development.”
