Madison Fusion Startup to Bring 600 Jobs to Former Plant

A shuttered meat packing plant in Madison is getting a second act as the birthplace of America's fusion energy future.

Realta Fusion, a University of Wisconsin-Madison spinoff, announced Wednesday it will transform the former Oscar Mayer headquarters into its new research and development hub. The site has sat mostly empty since Kraft Heinz closed operations there in 2017, ending nearly a century of manufacturing history.

The young company, founded in 2022 with just 50 employees, plans to grow its workforce to more than 600 people. These aren't minimum wage jobs either. Salaries range from $80,000 to over $180,000 annually, bringing significant economic opportunity to the region.

Realta will invest $67 million in building improvements and more than $500 million in equipment to construct its prototype magnetic mirror fusion machine. Fusion energy works by fusing atoms together, converting tiny amounts of mass into enormous amounts of clean power. While the technology won't be commercially ready until the early to mid-2030s, it represents one of the most promising paths to carbon-free energy.

CEO Kieran Furlong says Wisconsin beat out competitors in New Jersey, Tennessee, and Illinois because the state offered the complete package. "Wisconsin has all the jigsaw pieces," he told Wisconsin Public Radio. "We've got the leading R&D coming out of places like University of Wisconsin-Madison. We've got the manufacturing know-how in the core industrial centers around southeastern Wisconsin and up in the Fox River Valley."

The company secured $55 million in combined incentives from state and city governments, including tax exemptions and credits. Madison Mayor Satya Rhodes-Conway hopes Realta will attract additional fusion-related businesses and supply chain partners to the site.

The Ripple Effect

This project shows how old industrial communities can reinvent themselves for the clean energy economy. The Oscar Mayer plant once shaped entire neighborhoods around it as families built lives on good manufacturing jobs. Now a new generation of workers will have that same opportunity, this time building technology that could help solve climate change.

Wisconsin's strong university research programs and manufacturing expertise created a pipeline other states couldn't match. Furlong initially worried about the state's smaller talent pool compared to bigger markets, but UW-Madison's strength in plasma physics and nuclear engineering made the difference.

The company plans to break ground before year's end on what they're calling "The Realta Forge." The facility will repurpose existing buildings rather than demolishing them, honoring the site's industrial heritage while pointing toward its high-tech future.

A place that once fed America could soon help power it instead.
