Panattoni, one of the world's largest private developers, is pursuing a $1 billion data center campus, dubbed “Project Cornmaze,” across more than 430 acres in the towns of Beloit and Turtle, Wisconsin. Senior Vice President Brock Tomlinson presented details of the project at an invite-only lunch meeting, outlining plans for a 2 million sq. ft. campus for a hyperscale customer.

The developer claims the facility will feature a closed-loop water cooling system, potentially reducing water usage by 50%. An analysis by Applied Analysis projected significant economic benefits, including $636.7 million in economic output for Rock County and Wisconsin during construction and $6.5 million in annual property taxes. Principal analyst Jeremy Aguero suggested Project Cornmaze could become Rock County's largest principal taxpayer.

However, the project faces strong community opposition. Approximately 50 protestors, organized by No Beloit Data Center, gathered outside Panattoni’s private meeting, chanting slogans and expressing concerns about increased electricity bills and water usage. Nancy Hill, a Beloit resident, noted a 50% rise in her electricity costs, while Philip Gorman, a Rock County District Supervisor, criticized the private nature of the meeting, questioning if it violated Wisconsin’s Open Meetings Act. Brittany Keyes with No Beloit Data Center has filed a complaint with the Rock County District Attorney regarding this concern.

Town of Beloit Community Development Director Tim Kienbaum acknowledged the mixed reactions and the need to address environmental concerns related to a gravel quarry and nearby watershed before any decisions are made. Panattoni subsequently held a public open house to share information with the broader community, as the proposal moves through the review process, with public votes pending.
