Nigeria has officially linked its national electricity grid to the broader West African power network, marking one of the most significant steps in regional energy integration in almost two decades.
The Nigerian Independent System Operator, working closely with the West African Power Pool’s Information and Coordination Centre, carried out the synchronisation test in the early hours of Saturday, November 8, 2025. The four-hour operation connected Nigeria, Niger Republic, and parts of Benin and Togo to the rest of the West African grid under a single operating frequency.
Officials said the successful test represents a major breakthrough after years of attempts to align different national grids across the region. The only previous trial in 2007 lasted just a few minutes before it was suspended due to instability.
According to a joint statement from NISO’s leadership, the achievement was made possible through tighter coordination, real-time communication between control centres, stricter frequency control, and upgraded system-monitoring capabilities across participating countries.
With this synchronisation, the West African grid’s first zone — which includes Nigeria — is now effectively linked with the other parts of the sub-regional network. The development brings ECOWAS closer to its goal of building a unified electricity market where member countries can buy and sell power more efficiently.
For Nigeria, the connection opens doors to cross-border electricity trading, potential foreign exchange earnings, and the opportunity to put idle generation capacity to use. Power producers in the country have lost more than N2tn in the last 12 years due to energy that could not be delivered because of grid constraints.
The successful integration is also expected to encourage investment in transmission projects such as the North Core line in Birnin Kebbi and the Ajegunle 330kV substation in Lagos. The ability to draw power from neighbouring countries during emergencies — and supply them when needed — will also strengthen Nigeria’s grid stability and reliability.
Officials described the synchronisation as a historic milestone for West Africa and a clear sign of progress toward a competitive regional electricity market that could serve over 400 million people across 14 ECOWAS countries.
