Every one of those 12 data centers draws power and water from the same grid you rely on — reshaping where Wisconsin rates, land use, and water go, whether or not anyone put it to a vote. Here’s what that means, and what you can do about it.

Statewide, an industry analysis counts about 47 operational and 43 planned or under‑construction data centers in Wisconsin, plus an estimated $450 million in projected 10‑year tax revenue — the map below shows the 12 we’ve pinned so far, so help us map the rest. Statewide totals: American Edge Project & TECNA, Dec 2025.

What these facilities actually do

Hyperscale data centers aren’t ordinary warehouses. Each one draws megawatts of power and millions of gallons of water, and locks in decades of tax abatements — deals routinely approved with little public scrutiny. Across Wisconsin, that’s 12 facilities quietly reshaping the grid, water table, and tax base. See how the buildout works and where the power and water go.
