National Grid Under Threat as NISO Cracks Down on Irregularities Along Ikorodu–Sagamu Power Corridor

The Nigerian Independent System Operator (NISO) has launched a major enforcement and stakeholder intervention over what it described as serious operational irregularities threatening the stability of Nigeria’s national grid along the Ikorodu–Sagamu 132kV transmission corridor.

At a high-level meeting held at the Ikeja West Regional Office in Lagos, NISO’s Managing Director and Chief Executive Officer, Abdu Bello Mohammed, warned that persistent cases of offtake indiscipline, metering discrepancies, and energy accountability failures pose significant risks to the country’s electricity network and market integrity.

The meeting drew key stakeholders across the Nigerian Electricity Supply Industry, including representatives of the Nigerian Electricity Regulatory Commission (NERC), the Transmission Company of Nigeria (TCN), generation companies, distribution companies, and eligible customers.

Mohammed said investigations conducted by the System Operator uncovered anomalies capable of undermining operational reliability, weakening market confidence, and destabilising electricity supply if left unchecked.

“This is not a routine engagement. It is a decisive intervention aimed at protecting the integrity of the national grid and restoring operational discipline across the electricity value chain,” he stated.

According to him, the engagement was convened to present investigative findings, enforce compliance with the Electricity Act 2023, Grid Code, Market Rules, and Eligible Customer Regulations 2024, and agree on urgent corrective actions.

He stressed that restoring metering integrity and enforcing strict operational compliance are critical to sustaining reliable electricity supply nationwide.

The NISO boss further warned that continued breaches of established market and technical rules could expose the grid to wider operational vulnerabilities.

“Where discipline and compliance are compromised, the entire system is placed at risk. Stakeholders must act urgently to preserve the stability and integrity of the national grid,” Mohammed added.

The meeting is expected to produce enforceable compliance measures, implementation timelines, and stronger monitoring mechanisms as NISO intensifies efforts to strengthen governance and accountability within the power sector.

The intervention forms part of broader reforms targeted at improving operational transparency and ensuring long-term stability of Nigeria’s electricity transmission system.
