fusion

Commonwealth Fusion Systems has filed a generation interconnection request with PJM for its 400 MW Fall Line plant in Virginia, the first time a fusion developer has formally entered a major US grid queue.

Munich-based Proxima Fusion, RWE, Bavaria, and the Max Planck Institute for Plasma Physics have agreed on a two-stage, multibillion-euro roadmap to build a demonstration stellarator and a grid-connected commercial fusion plant at the decommissioned Gundremmingen reactor site.

Helion, Commonwealth Fusion Systems, and China's EAST reactor have each cleared critical technical barriers in early 2026, collectively marking the most concentrated period of fusion progress in the industry's history.
