The Nigerian Independent System Operator (NISO) has reached a significant milestone in regional energy integration by synchronizing the Nigerian power grid with the West African electricity network. In partnership with the West African Power Pool Information and Coordination Centre (WAPP‑ICC), the synchronization now includes parts of Niger, Benin and Togo, creating a unified grid that operates at a single frequency.
According to NISO Board Chairman Dr. Adesegun Akin‑Olugbade, the test was carried out on 8 November 2025, between 05:04 a.m. and 09:04 a.m. This breakthrough follows earlier attempts, such as a brief seven‑minute synchronization in 2007, and is made possible by improved system monitoring, frequency control and real‑time communication among the participating control centres.
The newly connected network integrates Nigeria, Niger and portions of Benin and Togo with the broader West African grid, enhancing reliability, stability and cross‑border electricity trade. The initiative aims to achieve operational unification of the regional grid, improve reliability through shared reserves, and enable cost‑effective power generation and trading under the West African Electricity Market (WAEM). Deeper institutional cooperation among member states is also expected to foster greater regional integration.
For Nigeria, the synchronization is expected to unlock stranded generation capacity, support energy exports and foreign‑exchange earnings, and improve grid resilience. It reinforces the country’s leadership in regional energy integration and opens the possibility of accessing international donor funding for key transmission projects.
Overall, the synchronization of the Nigerian power grid with the West African electricity network marks a major step toward a more integrated and reliable regional energy system, offering benefits that extend across the entire ECOWAS sub‑region and demonstrating the potential of cooperation in achieving a sustainable, interconnected energy future.
