Data Centers in Ohio
At least 89 data centers have been tracked across Ohio — the 5th state by data-center buildout in the country by capacity.
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 89 data centers draws power and water from the same grid you rely on — reshaping where Ohio 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 191 operational and 102 planned or under‑construction data centers in Ohio, plus an estimated $266 million in projected 10‑year tax revenue — the map below shows the 89 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 Ohio, that’s 89 facilities quietly reshaping the grid, water table, and tax base. See how the buildout works and where the power and water go.
