Realta Fusion, a nuclear fusion startup, has entered a strategic partnership with Madison Gas and Electric (MGE) and its parent company, MGE Energy, to explore the development of a 200-megawatt fusion power plant in Wisconsin. As part of the agreement, MGE Energy has made an undisclosed direct equity investment in Realta Fusion.

MGE will also provide technical support, equipment, and assistance with siting, permitting, and financing for the proposed plant. The collaboration aims to help MGE achieve its goal of net-zero carbon electricity by 2050 and signifies a broader trend of utilities and tech companies turning to fusion to meet the surging energy demands of AI data centers. Realta aims to commercialize its technology by the early 2030s and build the plant by the mid-2030s.
