Need this state’s camera data for your work?
We provide free custom extracts of everything we track — camera locations, brands, operators, dates, agencies, council agendas, and news coverage — to researchers, journalists, students, and advocates. Tell us the geography, time window, and format you need, and we’ll pull it for you. No charge, no strings.
Every one of those 3 data centers draws power and water from the same grid you rely on — reshaping where Montana 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 26 operational and 20 planned or under‑construction data centers in Montana, plus an estimated $300 million in projected 10‑year tax revenue — the map below shows the 3 we’ve pinned so far, so help us map the rest.

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 Montana, that’s 3 facilities quietly reshaping the grid, water table, and tax base. See how the buildout works and where the power and water go.
