A wave of nuclear energy programmes across West and broader sub-Saharan Africa is moving from decades of planning into active procurement, regulatory development and vendor engagement, with the region now representing one of the most significant emerging nuclear markets in the world.
The scale of the opportunity has been quantified. Africa’s nuclear sector is projected to add up to 15 gigawatts of new capacity by 2035, representing an investment opportunity of approximately $105 billion. Ghana, Uganda, Nigeria, Rwanda, Kenya, Niger and Ethiopia have all signalled plans to introduce nuclear power between 2030 and 2037.
The structural enabler underpinning much of this ambition is a now-unified West African grid. In November 2025, the West African Power Pool (WAPP) achieved full grid synchronisation for the first time, connecting all member states within a single network, with permanent synchronisation targeted for mid-2026. A synchronised regional grid is commercially significant for nuclear development because a single large reactor can supply multiple countries via interconnectors, spreading construction costs and improving the financial case for any individual project. The WAPP has set a long-term target of 10 gigawatts of nuclear capacity across the sub-region.
Ghana Leads the Field
Among West Africa’s newcomer nuclear states, Ghana is the furthest advanced. It has the most robust nuclear infrastructure in place of any new entrant nation in Africa, with institutional development, International Atomic Energy Agency (IAEA) milestone compliance, and investment in training infrastructure giving it a stronger foundation than most comparable countries at a similar stage. Nuclear Power Ghana (NPG) has signed framework agreements with both US-based NuScale Power and China National Nuclear Corporation (CNNC) and is targeting first nuclear power by the early-to-mid 2030s.
Nigeria: Capital Without the Infrastructure
Nigeria presents the starkest contrast to Ghana. Africa’s most populous country has the financial resources to support nuclear construction but is missing almost all of the infrastructure that Ghana has, and lacks a single coherent approach to the programme.
Progress is nonetheless accelerating on the legislative front. A bill to amend Nigeria’s Electricity Act to provide for the effective development and regulation of nuclear energy, specifically promoting Small Modular Reactors (SMRs) as a cost-effective and scalable solution, received its second reading in the House of Representatives in November 2025. Earlier gigawatt-scale ambitions with Russia’s Rosatom have been replaced by a more pragmatic modular strategy, and the Nigeria Atomic Energy Commission (NAEC) is working with the IAEA toward a Phase 2 Integrated Nuclear Infrastructure Review (INIR). A dedicated owner-operator entity, seen as the commercial backbone of any programme, is being targeted for formal creation within a one-to-two-year horizon.
Rwanda: Fastest-Moving Newcomer
Rwanda has emerged as the most rapidly advancing newcomer on the continent. In March 2026, the IAEA completed an INIR Phase 1 mission to Rwanda, and more than 234 Rwandan specialists are currently undertaking nuclear-related training. Rwanda plans to have its first SMR operational in the early 2030s. The country’s small grid size, estimated at around 550 megawatts of demand, makes it a natural candidate for the modular reactor approach, which is specifically designed for economies where a traditional gigawatt-scale plant would be too large for the existing system to absorb.
South Africa: Anchor of the Continental Market
Beyond West Africa, South Africa remains the continent’s only operational nuclear power producer and is dramatically expanding its ambitions. South Africa’s Integrated Resource Plan 2025 mandates more than 5 gigawatts of new nuclear capacity within a $128 billion national energy investment framework, and Koeberg Nuclear Power Station’s two reactors have received a 20-year operating licence extension keeping them running until 2044 and 2045. South African nuclear institutions are positioning the country as a potential technology standard-setter and training hub for the continental market, a role that would give its nuclear industry a significant commercial multiplier effect beyond its own borders.
Egypt: The Continent’s Next Operating Plant
Egypt is furthest ahead among Africa’s nuclear newcomers, with Russia’s Rosatom having begun construction on four large nuclear power plants with significant desalination capacity at El Dabaa in 2022, at an estimated cost of around $30 billion. The reactors are expected to come online in 2028.
The Financing Question Persists
Despite the momentum, the core challenge facing virtually every African nuclear programme remains unchanged. A senior official at the Rwanda Atomic Energy Board has said that none of Africa’s nuclear newcomer countries today is ready financially to immediately implement a nuclear power plant. Bridging that gap, whether through vendor financing, development finance institutions or regional cost-sharing arrangements enabled by the WAPP’s synchronised grid, will determine how many of the continent’s declared nuclear ambitions translate into concrete poured and reactors generating power.
The 5th Africa Nuclear Business Platform (AFNBP 2026), hosted by the NAEC in Abuja from April 21 to 23, is expected to be the next major forum where vendors, governments and investors attempt to close that distance between ambition and execution.
