Data centers fuel $1 billion in Wisconsin business growth, but some question long-term impact

Many companies don’t publicly report details on data center business they do, so it’s impossible to tally total economic impact in Wisconsin. But there are other examples.

Trane Technologies is manufacturing cooling systems for data centers in La Crosse, where it was founded in 1913, and says data centers are a strong part of its business. In November 2023, Excellerate opened a 385,000-square-foot plant in Little Chute, primarily to manufacture “modular electrical buildings” for data centers. Maysteel, a Washington County manufacturer, opened a data center hub in November 2024 and announced in February it is expanding the operation.

The sheer demand to outfit data centers has meant that some business has trickled down from larger companies to smaller ones.
