Ohio data centers, in short
Ohio has 188 data centers identified from primary sources, spread across 57 cities and counties and run by 59 operators. The largest concentration is New Albany, with 40 data centers, followed by Columbus with 25 and Cleveland with 16.
The operators with the most data centers in Ohio are Amazon Web Services (17), Google (12), ark data centers (8), Cologix (7), Meta (7). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings.
Not every operator discloses size. In Ohio, 44 publish a floor area and 33 publish a power figure, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced.
PJM runs the wholesale power market and the high-voltage grid for all of Ohio. 2 statewide measures governing data centers are on record, alongside 12 local pauses. 7 named projects in Ohio are delayed, blocked or under challenge, and the capital atlas records 10 sites here carrying $38.5B in announced commitments.

Ohio data centers, answered from the record
How many data centers are in Ohio?
The industry reference count for Ohio is 240 facilities. This map places 188 of them from primary sources, each with a source record you can open, and every entry names the operator, the county, and the grid operator that serves it. The rest are mostly small regional colocation providers and enterprise buildings that no public register describes.
Where are Ohio's data centers?
They are listed on this page city by city. By city: New Albany (40), Columbus (25), Cleveland (16), Hilliard (9). By county: Franklin County (56), Licking County (32), Cuyahoga County (26).
