West Africa Moves Closer To Unified Power Grid As NISO, WAPP Deepen Coordination
Princess-Ekwi Ajide
As West Africa pushes towards a more reliable and interconnected energy future, technical cooperation is emerging as the backbone of a unified regional power system.
The Nigerian Independent System Operator (NISO) and the West African Power Pool (WAPP) have intensified efforts to align operations ahead of Phase II of regional grid synchronisation, scheduled for June 2026.
The move signals a critical step towards real-time integration of national electricity grids across the sub-region.
During a high-level technical visit to the National Control Centre in Osogbo, both bodies focused on system readiness, operational protocols, and detailed studies required to ensure seamless synchronisation.
Speaking at the session, NISO’s Executive Director for System Operation, Engr. Nafisatu Asabe Ali, underscored the complexity of transitioning to a fully synchronised grid.
She noted that success would depend on strict compliance with unified standards, including frequency control, voltage stability, and contingency management across interconnected networks.
She explained that the National Control Centre remains central to maintaining grid stability, overseeing real-time operations through its advanced SCADA/EMS platform while coordinating power dispatch and system balancing within Nigeria and across regional links.
A key infrastructure highlight is the Ikeja West–Sakété 330kV transmission line, which serves as a vital cross-border link between Nigeria and the Republic of Benin, reinforcing regional electricity exchange and load balancing.
NISO also revealed ongoing investments in grid modernisation, including an upgraded control system and the development of a new National Control Centre to enhance resilience and operational efficiency.
On the regional front, WAPP Secretary General Abdoulaye Diaw praised Nigeria’s growing role as a stabilising force within the West African grid, urging sustained investment in infrastructure and technical capacity to ensure the success of the synchronisation phase.
With trial simulations and system tests already underway, stakeholders say the initiative could significantly improve electricity reliability, optimise power distribution, and strengthen energy security across West Africa.
