Nigeria has achieved a historic breakthrough in regional energy integration, following the successful synchronisation of its national electricity grid with the West African Power Pool (WAPP) on 8 November 2025, between 05:04 a.m. and 09:04 a.m. The test, coordinated by the Nigerian Independent System Operator (NISO) and the WAPP Information and Coordination Centre (WAPP-ICC) in the Benin Republic, connected Nigeria (Area 1), Niger, Benin, and Togo to the broader West African grid (Areas 2 and 3) in a single unified frequency for the first sustained period in Nigeria’s history.
This achievement marks a significant advancement, particularly given that the last synchronisation attempt in 2007 was unsuccessful and lasted only seven minutes. The 2025 test succeeded due to enhanced system monitoring, real-time communication between national control centres, stricter frequency management, and harmonised operational standards across the region.
