Realta Fusion and Madison Gas and Electric Announce Partnership to Explore 200-MWe Wisconsin Fusion Plant

Realta Fusion and Madison Gas and Electric (MGE) announced a strategic partnership on September 2, 2026 to jointly explore a 200-megawatt-electric, grid-connected fusion power plant in Wisconsin — among the first such utility-fusion partnerships in the US. MGE made a direct equity investment in Realta in this initial phase and committed equipment, engineering, and technical support plus assistance with siting, permitting, interconnection, and financing for the prospective plant. Realta's magnetic mirror prototype, Hammir, is under development at its new Realta Forge R&D headquarters at Madison's former Oscar Mayer site.
