Nigeria’s national electricity grid has been successfully synchronised with the broader West African power network — a historic breakthrough in regional energy integration that brings the subcontinent closer to a single, unified electricity market.
The milestone test, jointly executed by the Nigerian Independent System Operator (NISO) and the West African Power Pool (WAPP) Information and Coordination Centre, took place between 5:04 a.m. and 9:04 a.m. on Saturday, November 8, 2025. It connected Nigeria, the Niger Republic, and parts of Benin and Togo to the rest of the West African grid for the first time in a fully synchronised operation at a single frequency.
In a joint statement on Sunday, NISO Board Chairman, Adesegun Akin-Olugbade, and Managing Director/Chief Executive Officer, Abdu Bello Mohammed, described the achievement as “a major leap toward a stable, reliable, and interconnected electricity market within the ECOWAS sub-region.”
“The successful synchronisation test marks a breakthrough in the ongoing effort to establish a unified West African electricity grid operating at a single frequency,” the statement read.
The achievement follows nearly two decades of technical collaboration under the WAPP initiative, which aims to link the power systems of 15 ECOWAS member states. A previous physical test in 2007 lasted only seven minutes before being halted due to system instability and lack of coordination.
This latest success, according to NISO and WAPP, was made possible by improved coordination between control centres, stricter frequency regulation, enhanced real-time communication, and harmonised operational standards across participating countries.
The synchronisation effectively merges Area 1 (Nigeria, Niger, and parts of Benin and Togo) with Areas 2 and 3, covering the remaining West African countries, under a single operational grid — a key step toward full regional power trade.
Industry experts say the move will deepen regional energy cooperation, lower electricity costs, and improve grid reliability by allowing countries to share reserves and exchange surplus power. For Nigeria, it strengthens its leadership role in West Africa’s electricity market, offering opportunities for cross-border energy trading, foreign exchange earnings, and the utilisation of stranded generation capacity from underused power plants.
A recent report by The PUNCH noted that Nigeria’s power-generating companies lost over ₦2.31 trillion in the past 12 years due to unutilised electricity, mainly from grid and operational limitations.
Beyond its technical and economic implications, the synchronisation opens new doors for international funding and investment in Nigeria’s transmission infrastructure. Projects such as the North Core Transmission Project in Birnin Kebbi and the Ajegunle 330kV Substation in Lagos are expected to benefit from increased confidence among regional partners and donors.
The integration also enhances grid stability and resilience, enabling Nigeria to either supply or draw electricity from neighbouring systems during emergencies — a major step toward consistent power delivery for millions of consumers across the sub-region.
“This marks a historic milestone in regional energy cooperation and affirms Nigeria’s central role in driving West Africa’s economic growth through power sector collaboration,” the NISO statement concluded.
With the success of the test, West Africa is now closer to realising its long-term vision of a single, competitive electricity market capable of providing sustainable energy access to over 400 million people across the ECOWAS region.
