The Nigerian Independent System Operator (NISO), in collaboration with the West African Power Pool Information and Coordination Centre (WAPP-ICC), has announced the completion of synchronisation test between the Nigerian power grid which includes Niger Republic and parts of Benin and Togo and the rest of the West African power grid.

The test according to a statement issued by NISO was conducted on Saturday, 8th November 2025, between 05:04 hours and 09:04 hours. This test, for the operator marks a major breakthrough in the ongoing effort to establish a unified West African electricity grid operating at a single frequency.

The WAPP initiative aims to achieve operational unification of the regional grid, improve system reliability through shared reserves, enable cost-effective power generation and trading under the West African Electricity Market (WAEM), and strengthen institutional cooperation among member system operators.

The synchronisation connects Area 1 (Nigeria, Niger, and parts of Benin and Togo) with Areas 2 and 3 (the rest of West Africa), creating a single operational grid that enhances reliability, stability, and cross-border energy exchange across the ECOWAS region.
