Africa’s Nuclear Buildout by the Numbers

An open dataset now tracks civilian nuclear programs across 20 African countries. One operates a commercial plant (South Africa's Koeberg, 1,860 MW), one is under construction (Egypt), seven are in active preparation under IAEA milestones, and ten are exploring. African nations are collectively exploring 15 GW of new nuclear capacity. South Africa's government approved an Integrated Resource Plan in October 2025 calling for 5,200 MW of new nuclear by 2039, with 1,200 MW targeted for 2036.

Where this fits

This matters because it demonstrates nuclear's recovery as a preferred firm power source in energy-poor regions. Africa faces electricity deficits that neither coal nor renewables alone can solve reliably: solar and wind require gas firming and long-distance transmission, while nuclear delivers dense, dispatchable output on compact land. The absence of such firm capacity in Africa's grid planning has been the binding constraint on industrial growth. That 20 countries are now seriously exploring nuclear, not as ideology, but as engineering, undercuts the proposition that firm power is optional or that renewables-only grids work at scale.

What it means

Australia's energy policy proceeds in near-total isolation from what working energy systems are doing. The Inflation Reduction Act has reset US nuclear economics; the IRA funds advanced reactors, not renewables subsidy. Africa's shift signals that countries with real electricity poverty are choosing density and dispatchability, not variable generation. Australia, energy-rich and grid-stable, is instead legislating away nuclear and betting the grid on weather. The global pivot toward firm power makes Australian dependence on China's battery supply chains and gas firming look less like a transition and more like a vulnerability.
