U.S. data-center footprint

Ohio

DataCentersExposed tracks 118 AI data centers in Ohio — 10 operating and 42 in the pipeline — across 32 counties, drawing 23.8 GW of reported power demand from 19 tracked corporate operators. Ohio's data-center tax break is projected to cost the state $130.4M in forgone revenue in FY2024.

The story so far

Ohio at a glance

The largest footprint in Ohio belongs to Amazon.com, Inc., behind 27 tracked facilities. Alphabet Inc., Meta Platforms, Inc., and Vantage Data Centers Holdings, LLC round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.

Geographically, the buildout clusters: Franklin County leads Ohio with 20 facilities and a composite risk score of 54/100. Licking County and Union County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.

Ohio is not done growing. 42 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.

We also surface the accountability trail: 8 state bills mentioning data centers and 6 recent news items are tracked for Ohio below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.

2035 Buildout Outlook

via PNNL IM3 (CC BY 4.0)

Under the model's moderate-growth scenario (5%/yr annual load growth), PNNL's IM3 model sites about 5 standardized 36 MW campuses in Ohio by 2035 — roughly 180 MW of new electricity demand and ~174 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 29 campuses (1.0 GW). For scale, we currently track 118 real data centers in Ohio (23.8 GW of reported power).

Modeled new campuses by demand-growth scenario
  • Low growth3
    108 MW · ~104 M gal/yr cooling water
  • Moderate growth5
    180 MW · ~174 M gal/yr cooling water
  • High growth14
    504 MW · ~487 M gal/yr cooling water
  • Higher growth29
    1.0 GW · ~1.0 billion gal/yr cooling water

The model assigns ~100% of these campuses' cooling to evaporative water cooling in Ohio (the rest to mechanical/air cooling), a split it derives from local water stress and wet-bulb temperature.

These are modeled candidate sites, not announced or permitted facilities. PNNL's IM3 model places identical 36 MW unit-campuses at feasible locations under each scenario — it shows where demand could concentrate, never a specific parcel. Figures use a market-gravity weight of 50. How the model works.

Methodology & sources

Facility counts include operating, under-construction, proposed, and permitted sites. Capacity (MW) combines operator disclosures, interconnection-queue estimates, and research datasets; see each facility for provenance. County risk scores weight project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%), renormalized over measured factors.

Every row carries a confidence level (high / medium / low) and a source URL. Spot an error? Tell us.
