In rural Wisconsin, a town pushes aside a plan to build a massive data center
Cassville, Wis. — An attorney read from a laptop propped atop a snowplow.
To his left was a Caterpillar street grader, and to his right, a dusty workbench. A disheveled American flag hung next to a red toolbox in the center of the impromptu stage.
Dozens of southwest Wisconsin residents recently forsook part of the local high school’s track-and-field meet so they could cast their votes inside the town of Cassville’s garage. The attorney had been retained by the town’s elected leaders to read the soon-to-be-newest regulation.
The unanimous outcome — 44 ballots in favor of banning data centers, none against — reflected a backlash of hostility to unwelcome incursions by big tech into rural spaces.

Residents instructed their town board to put a stop to the billion-dollar proposal by an anonymous developer after learning their community was on the shortlist.
Even promises of 50 jobs and more than $5.5 million in annual property tax revenue weren’t enough to make up for the loss of about 500 acres of Wisconsin’s Driftless area.
The pastoral landscape — known for rolling bluffs that straddle the locks and dams of the nation’s upper Mississippi River — possesses a bountiful aquifer, a temperate climate and few land regulations.
Cassville’s ordinance is the latest move by a Midwestern community seeking to protect the qualities that make life so appealing to people — and data centers.
Pushback over the power-hungry facilities that make the cloud run are occurring across the country, as companies expand in states like Mississippi and Tennessee.
Residents in Port Washington, Wisconsin, were the first in the nation to pass a referendum that would prevent their city from offering generous tax incentives without first obtaining voter approval.
Wisconsin lawmakers — some of whom previously supported a state sales tax exemption for new data centers — sponsored bills that would prevent developers from using confidential nondisclosure agreements when prospecting for new sites.
And in Clayton County, Iowa, directly across the river from Cassville, officials are considering zoning, setback and size restrictions.
Cassville residents fear data centers will devalue their properties, contaminate their wells and increase their electric bills.
“This is the Driftless area for Christ’s sakes,” said John Hawn, who retired to the area several years ago. “I suppose they didn t expect any problems coming into a small town.”
‘No information’
The Cassville project has been shrouded in secrecy. That includes the proposed location and what company will use it, leaving residents to fill in the vacuum with a frenzy of social media engagement.
“I don t know really what to think about it, because there s no information,” town Supervisor Scott Riedl said.
Ron Brisbois, executive director of the Grant County Economic Development Corp., has met with a developer but to-date declined to identify the company that is scouting for locations so as not to jeopardize the project.
But, he said, following Cassville’s vote, the town’s appeal is its proximity to electricity, specifically the high-voltage Cardinal-Hickory Creek transmission line that entered service in September 2024.
Brisbois estimated the data center would require 400 to 500 megawatts of power — a lot, even by the new transmission line’s standards.
But, the town’s attorney, Eric Hagen, said if Cassville can make it inconvenient, the data center developer may look elsewhere. The company also is considering sites in Indiana and North Dakota.

“My read of the situation right now: They re looking for the lowest hanging fruit with the least amount of regulations,” Hagen said.
That is where Cassville’s new ordinance comes in.
It prohibits data centers in the town for up to two years and prevents land
