Realta Fusion partners with Madison Gas and Electric for first U.S. fusion power plant
Fusion energy startup Realta Fusion has signed a deal with Wisconsin utility Madison Gas and Electric to build one of the country’s first grid-connected fusion power plants, expected to be operational in the mid-2030s. The 200-megawatt facility would provide enough electricity for a small city and marks part of an emerging trend where utilities are increasingly partnering with fusion startups as they seek reliable baseload energy sources beyond wind and solar. Such partnerships offer mutual benefits: utilities gain early access to potentially transformative technology, while startups receive engineering support, site interconnection opportunities, and financial backing. Realta is converting a former Oscar Mayer factory in Madison into its R&D hub and has also received an equity investment from the utility company as part of the deal. This development reflects growing interest in fusion energy among utilities worldwide amid rising electricity demand—particularly driven by AI data centers—and concerns over intermittency with renewable sources. Other notable fusion startups, such as Commonwealth Fusion Systems and Helion Energy, have already signed similar agreements.
