On April 27, PJM Interconnection closed its first full interconnection cycle since 2022. Under a reformed application process, 811 developers submitted generation projects capable of generating 220 gigawatts. About 400 megawatts of that total share comes from Commonwealth Fusion Systems, which submitted an application for its ARC fusion power plant. This is a notable milestone for the industry: it is the first time a developer has requested to connect a commercial fusion power plant to a major grid.
