A Historic Step Toward Regional Energy Integration
The Nigerian Independent System Operator (NISO) has achieved a significant milestone by successfully synchronising Nigeria’s national electricity grid with the broader West African power network. This historic event, conducted in collaboration with the West African Power Pool Information and Coordination Centre, marks a major breakthrough in regional energy integration.
The test took place between 5:04 am and 9:04 am on Saturday, November 8, 2025, connecting Nigeria, the Niger Republic, and parts of Benin and Togo to the rest of the West African grid. This is the first successful attempt at establishing a unified regional power system operating at a single frequency, linking 15 West African countries.
A joint statement from the Chairman of NISO’s Board of Directors, Adesegun Akin-Olugbade, and the Managing Director/Chief Executive Officer, Abdu Bello Mohammed, described the achievement as a major leap toward creating a stable, reliable, and interconnected electricity market in the ECOWAS sub-region.
The statement highlighted that the synchronisation test was conducted between 05:04 hours and 09:04 hours on Saturday, 8th November 2025, and marked a breakthrough in efforts to establish a unified West African electricity grid operating at a single frequency. The test connected Area 1 (comprising Nigeria, Niger, and parts of Benin and Togo) with Areas 2 and 3, which cover the remaining West African countries, under a single operational grid.
This development is a cornerstone in the West African Power Pool plan to create a unified electricity market. It will allow countries to trade electricity efficiently, reduce supply costs, and improve grid reliability through shared reserves. For Nigeria, this synchronisation positions it as a pivotal player in the region’s electricity ecosystem, enabling cross-border energy trading, foreign exchange earnings, and unlocking stranded generation capacity from underutilised power plants.
Challenges and Progress
Efforts to synchronise the sub-regional grids have been ongoing for nearly two decades. However, the only previous physical test, conducted in 2007, lasted barely seven minutes before being discontinued due to instability and lack of coordination. The latest achievement, according to the joint statement, was made possible through enhanced coordination, real-time communication among control centres, stricter frequency control, improved system monitoring, and harmonised operational standards between NISO and the WAPP Information and Coordination Centre.
The synchronisation also improves grid stability and resilience by allowing Nigeria to draw or supply power to neighbouring systems during emergencies. This enhances reliability for millions of electricity consumers across the sub-region.
Economic and Strategic Implications
For Nigeria, the synchronisation strengthens its leadership role in regional energy cooperation and provides access to international donor funding for strategic transmission infrastructure. Projects such as the North Core Transmission Project in Birnin Kebbi and the Ajegunle 330 kV Substation in Lagos are expected to benefit from renewed investor confidence and technical collaboration under the West African Electricity Market.
According to recent reports, power-generating companies in Nigeria lost a staggering N2.31tn over the last 12 years due to electricity that could have been generated but was left unused as a result of grid and operational constraints. The successful synchronisation addresses these challenges and opens new opportunities for efficient energy distribution and management.
Future Prospects
The successful synchronisation marks a historic milestone in regional energy cooperation and demonstrates NISO’s technical capacity to manage complex grid operations in line with international standards. It affirms Nigeria’s central role in driving regional economic growth through energy cooperation.
With this achievement, West Africa moves a step closer to its goal of creating a single, competitive electricity market capable of delivering sustainable power to more than 400 million people across 14 countries under ECOWAS.
