How many data centers are in Ohio?

More Than Just Parks tracks 154 active data center facilities in Ohio, each citing a public source: 95 operating, 27 under construction and 32 proposed. 28 more were canceled, withdrawn, suspended or blocked.

How much electricity do Ohio's data centers use?

We don’t publish a state total, and the reason matters: about six in ten facilities here never disclose a capacity, so any sum would look like a census of Ohio's data center load while leaving out the sites that stayed quiet. Each facility page shows the figure its own source states. A single large campus can draw as much power as a small city.

Are Ohio data centers near protected land?

25 of the tracked facilities in Ohio sit within 10 miles of protected public land, measured to the real boundary of the nearest national park, wilderness area, wildlife refuge or conservation area; none sit within a single mile.

Which county in Ohio has the most data centers?

Franklin County has the most, with 44 tracked data centers, followed by Licking County (23) and Cuyahoga County (17).

Are there proposed data centers in Ohio?

Yes. We track 32 proposed data centers in Ohio, including Stargate Ohio (EnergiAcres, Belmont County campus), Buck Canyon Data Center (Stuart Site, Adams County) and Cologix Johnstown Campus. 3 of them sit within 10 miles of protected public land.

Who is building data centers in Ohio?

The most active operators in Ohio are Amazon Web Services (16 sites), Google (8 sites) and CyrusOne (6 sites), counted by sites, not megawatts.
