Why this score?
Four weighted factors drive the Hocking County risk score. Methodology is fully documented — each input is public data or a reasoned proxy.
Below-average transmission capacity. Hyperscale loads would require significant infrastructure investment.
Limited water capacity. Cooling-tower designs face significant constraints; closed-loop or air-cooled would be required.
Limited available large-acreage land. A structural disincentive to greenfield hyperscale development.
No documented activity in or near the county.
Water infrastructure
Any hyperscale data center in Hocking County would need an Ohio EPA NPDES permit and (for surface water) coordination with the relevant watershed authority. The water source is Hocking River.
Surface-water capacity for hyperscale cooling depends on flow volumes, downstream-user demand, and Ohio EPA NPDES discharge limits. Inland river sources are usually the binding constraint on data-center designs that depend on evaporative cooling.
A single hyperscale data center using evaporative cooling can require 1–5 million gallons per day. Closed-loop and air-cooled designs reduce that draw at higher capital cost — a tradeoff that becomes more relevant as Ohio's water-permitting reviews lengthen.
Electric infrastructure
Grid capacity and transmission access are the single biggest driver of where hyperscale developers actually site projects. Hocking County is served by AEP Ohio + South Central Power Cooperative.
AEP Ohio is the dominant utility for Central, Eastern, and Southern Ohio. Under Ohio HB 15's behind-the-meter tariff, AEP allows on-site generation that bypasses normal local grid review — the most aggressive data-center accommodation of any Ohio utility.
A single major substation upgrade or new transmission-line announcement can change the power factor significantly without any public proposal having been filed. Utility-survey activity at specific industrial parcels typically precedes a hyperscale proposal by six to twelve months.
Adjacent county activity
Hyperscale campuses cluster near existing transmission and water infrastructure. Activity in adjacent counties is the single best predictor of where a developer will look next.
Pike County — Piketon's PORTS Technology Campus is a planned 10-gigawatt data-center development on the former DOE uranium-enrichment site — the largest single project announced in U.S. history.
Franklin County — Hilliard's Bloom Energy fuel-cell installation — 73 MW Amazon + AEP Ohio data-center generation, the largest in North America — is in administrative-court litigation.
State legislative context
Ohio's 2025–2026 legislative session has produced multiple bills targeting hyperscale data centers. Each affects Hocking County directly, regardless of whether a project is currently proposed here.
HB 15 (signed into law in 2025) created the "behind-the-meter" generation framework allowing data centers to install on-site generation that bypasses some local zoning review and PUCO oversight. HB 695 (in committee) would prohibit local officials from signing non-disclosure agreements with data-center developers, with $1,000 fines per violation.
The proposed Ohio Constitutional Amendment from Ohio Residents for Responsible Development (ORRD) would ban hyperscale data centers above 25 MW absent a county-level vote. The campaign needs 413,488 valid signatures from at least half of Ohio's 88 counties by July 1, 2026.
