JOHANNESBURG, South Africa — Africa’s nuclear ambitions are widening in 2026, with Egypt building four reactors and South Africa preparing fresh tenders, but steep financing hurdles are still keeping many national plans in the study phase, March 29, 2026.
Why nuclear power in Africa is back on the agenda
According to IAEA’s 2025 outlook for the continent, more than 20 African countries are exploring nuclear energy pathways even though Africa still has just one operating nuclear power plant and more than 500 million people lack electricity. The agency’s case studies span Egypt, Ghana, Kenya and Nigeria, underscoring how nuclear is being discussed less as a fringe technology and more as a potential answer to chronic power shortages, industrialization goals and the need for firm low-carbon generation.
The conversation is no longer purely theoretical. In a separate IAEA review of global nuclear trends, the agency said South Africa remains Africa’s only current nuclear power producer while Egypt is constructing four reactors, a sign that the continent’s nuclear debate has moved beyond policy papers in at least one market.
Why financing remains the biggest hurdle for nuclear power in Africa
The bigger problem is money. Even the World Bank’s June 2025 decision to end its long-standing ban on funding nuclear energy projects does not suddenly make African projects bankable. The bank said electricity demand in developing countries is expected to more than double by 2035, a scale that would require more than doubling today’s annual investment in generation, grids and storage.
That challenge is sharper in Africa because governments are already competing for scarce, expensive capital. Reuters reported this month, citing S&P, that African sovereigns are expected to borrow about $155 billion in 2026 and that outstanding commercial sovereign debt could rise to just above $1.2 trillion by year-end. In that setting, large nuclear projects can look less like standalone energy investments and more like tests of fiscal stamina, currency resilience and political continuity.
South Africa’s latest procurement thinking shows how sponsors are trying to reduce that risk. In Reuters’ March 2026 report on NECSA’s new reactor drive, the company said it prefers turnkey or EPC structures for a new research reactor and is also moving toward an SMR tender, both within a broader 80 billion rand infrastructure push. SMRs may shrink plant size, but they do not remove the need for strong regulation, dependable off-takers and long-tenor capital.
That is the central tension for nuclear power in Africa. The technology may promise stable output and energy security, but lenders still want credible regulation, grid readiness, predictable procurement and borrowers that can absorb delays or cost overruns over a decade or more.
A long runway from ambition to execution
This is also a story of how long nuclear timelines can stretch. Reuters reported in 2010 that Egypt aimed to build four plants by 2025. By 2016, Reuters reported that Russia would lend Egypt $25 billion to finance the project, underscoring how dependent first-of-a-kind African builds can be on state-to-state capital. And in 2017, Reuters reported that a South African court declared a Russia-linked nuclear plan unlawful, showing how procurement and governance disputes can freeze momentum for years.
The lesson from that history is not that African nuclear plans are unrealistic. It is that they are unusually sensitive to financing structure, legal process and political durability. Announcements come quickly; financial close does not.
What nuclear power in Africa needs next
Africa’s nuclear ambitions are unlikely to disappear. The power deficit is too large, the search for firm generation is too urgent and the political appeal of long-life strategic infrastructure is too strong. But unless multilateral lenders, export-credit agencies and African governments can bring down the cost of capital and standardize risk-sharing, the continent’s nuclear map will remain a list of bold intentions with only a handful of bankable projects.
For now, Egypt shows that execution is possible, South Africa shows that capability can be revived, and the rest of the field shows the real constraint: not interest in nuclear, but access to patient capital.
