Proxima Fusion to Build World's First Commercial Stellarator Fusion Power Plant in Bavaria
FUSION & ADVANCED NUCLEAR POWER
Proxima Fusion, in partnership with the Free State of Bavaria, RWE, and the Max Planck Institute for Plasma Physics, is set to develop the world's first commercial stellarator fusion power plant, Stellaris, at a former nuclear fission site in Gundremmingen. This follows the construction of a demonstration stellarator, Alpha, in Garching, anticipated to be operational in the 2030s and to achieve net energy gain.
The overall project aims to validate fusion technologies, create thousands of jobs, and integrate fusion into Europe’s energy mix. The initiative has an estimated cost of €2 billion, with funding from private investors and potential state co-financing.
