This paper argues that repowering Germany's coal fleet and shut-down nuclear sites with advanced nuclear energy would: eliminate 104 MtCO₂e of annual emissions; deliver 223 TWh/year of clean electricity from existing grid connections; avoid up to EUR 300-400 billion in planned transmission spending; and cut industrial electricity costs towards the $52-64/MWhe range.
Repowering Germany's 28.3 GW coal fleet and three shut-down nuclear sites with advanced nuclear energy would: eliminate 104 MtCO₂e of annual emissions (14% of national total); deliver 223 TWh/year of clean electricity from existing grid connections—128 TWh more than coal currently provides; avoid up to EUR 300-400 billion in planned transmission spending; and cut industrial electricity costs towards the $52-64/MWhe range—competitive with global rivals and below any other clean, firm generation alternative. Combined with continued renewable expansion, this would put Germany on the fastest credible pathway to a fully decarbonized energy system.
The REPOWER system—Terra Praxis's standardized, modular building system—targets capital costs of approximately $2,000/kWe, versus $8,000-10,000/kWe for conventional nuclear in the West. It achieves this through a technology-agnostic open architecture, Design for Manufacture andAssembly (DfMA), factory-produced "heat box" reactor modules, and product-based licensing ("license once, build many"). Critically, 75%of global energy demand lies outside the power sector—in industry, transport, and heating. Repowered sites can supply not just electricity but process heat, hydrogen, district heating, and power for data centers, unlocking markets that renewables cannot serve alone.
