The Nigerian Independent System Operator (NISO), in collaboration with the West African Power Pool Information and Coordination Centre (WAPP-ICC), has successfully carried out the long-awaited synchronization 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 was conducted on Saturday, 8th November 2025, between 05:04 hours and 09:04 hours, and marks a major breakthrough in the ongoing effort to establish a unified West African electricity grid operating at a single frequency.
