The Nigerian Independent System Operator (NISO) has called for stronger collaboration among stakeholders in the Nigerian Electricity Supply Industry (NESI) to address emerging challenges threatening grid stability and ensure a more reliable power supply.
The Managing Director and Chief Executive Officer of NISO, Engr. Abdu Bello Mohammed, made the call while delivering his opening remarks at a two-day workshop titled “Strengthening Grid Stability: A Collaborative Workshop for NESI Stakeholders,” held on August 19, 2026, at the Jebba Power Station.
Mohammed said grid stability remained the foundation for the security, reliability and resilience of Nigeria’s electricity supply system, stressing that achieving a stable grid required operational discipline, effective system management and coordinated action across the entire electricity value chain.
He identified generation and transmission constraints, changing demand patterns, frequency excursions, voltage-security challenges and the increasing diversity of energy resources as some of the complex conditions confronting the Nigerian power system.
According to him, maintaining stability under these circumstances requires continuous vigilance and a holistic approach that combines operational excellence with long-term strategic planning.
The NISO boss explained that frequency excursions could arise from several interconnected factors, including sudden loss of generation or load, inaccuracies in forecasting and scheduling, fault-induced disturbances, inadequate system inertia and the response characteristics of generating units during system events.
He noted that NISO’s ongoing compliance monitoring had reinforced the importance of adherence to technical performance standards, including Free Governor Control requirements.
“However, the broader lesson remains that grid stability is a shared responsibility and can only be achieved through coordinated action across all segments of the industry,” he said.
Mohammed stressed that resolving the challenges facing the grid would require more than technical interventions, noting that accurate and timely operational information, adequate frequency and voltage control resources, effective reserve management and strict compliance with the Grid Code were equally essential.
He also emphasised the importance of seamless coordination among the Nigerian Independent System Operator, Transmission Company of Nigeria (TCN), Generation Companies (GenCos), Distribution Companies (DisCos), regulators and other industry stakeholders.
The NISO chief executive further highlighted the need to align present operational decisions with long-term system
