Ohio evidence index · last reviewed 11 September 2026

The headline is not the finding.

A major-project first pass plus a physical-facility inventory and a reviewed claim-and-inference desk. We separate grid demand from IT capacity, construction from operation, supported jobs from permanent headcount, and a draft permit from measured water use.

This is not “every Ohio data center.”It covers major projects with useful public evidence. A commercial directory count can mix a campus, a building, a tenant suite and a network point-of-presence. The public first pass does not inherit those rows or call missing facilities zero.
Included now

Major hyperscale projects plus 29 colocation, enterprise and hyperscale building records directly identified by operators, with lifecycle status preserved.

Still missing

The city says 15 companies operate 40+ New Albany facilities. We now expose 43 named municipal construction/project leads, but opening dates and identities are not reconciled to that operating denominator. CyrusOne COL1, private/government sites, retired facilities and observed outcomes remain queued.

Not additive

Three Google campuses, a multi-building AWS expansion and a four-data-center Vantage plan are each one record here. The record count is not a building count.

Where the evidence points

Projects and buildings are different layers.

Orange markers are project or campus records. Cyan markers are operator-identified physical facilities or buildings. Records are anchored to Census geography centroids—not parcel coordinates—and dense Central Ohio markers are visibly offset to remain tappable.

What the first pass reveals

Ohio’s public numbers speak different languages.

The most impressive-looking figures are usually not directly comparable. The honest statewide view starts by refusing to add them.

1 GW+

Meta design capacity

Company description of New Albany after construction—not metered load and not a utility-service commitment.

192 MW

Vantage OH1 IT load

Planned critical IT capacity across three buildings—not total campus grid demand.

696 MW

Vantage OH2 IT capacity

Planned capacity in Millersport. Its adjacent-generation and no-rate-impact claims still need regulatory records.

$20B+

Google Ohio investment

Company statewide investment-to-date claim; it cannot be allocated across three campuses from the reviewed disclosure.

New Albany building reconciliation

The city names the buildings. It does not prove they are operating.

We transcribed every current municipal Commercial Projects entry described as a “new data center” or “new data building.” This creates a public identity queue without turning a construction-project page into an operating-facility count.

8company labels, including one unresolved NBY label
4already crosswalked to physical QTS building records
2support buildings explicitly excluded from this ledger
What 43 does—and does not—mean.It is a count of named municipal construction/project entries, including future work and repeated generic building labels. It does not verify 43 distinct operating facilities and it does not reconcile the city’s separate “15 companies operate 40+ facilities” claim. That requires opening dates, identities and lifecycle evidence.

This ledger excludes an AWS security-control building and a Meta administration building that the city lists because their descriptions identify support uses rather than data buildings. Unknown operating status remains unknown.

Claims and inferences, reviewed

What the record actually establishes.

This is not an automated news feed. One card tests an exact published count; others label a common inference or unit mistake before testing it. We do not attribute synthetic wording to a source that never said it.

Published count · statewideNot reconstructed

Ohio has more than 200 data centers.

Ohio’s consumer advocate repeats a commercial-directory count. It is a useful market signal, not a state census with a public building-level denominator. DataCenterData does not adopt 200+ as its own total.

Inference tested · power / ratesOverstated

Treating the 85% tariff as proof that residents cannot be affected by data-center power costs.

AEP Ohio’s tariff gives real protection against stranded distribution investment: large new loads face minimum demand, collateral and cancellation obligations. It does not prove that generation, transmission or wholesale-market costs can never affect household bills.

Unit distinction · taxes / jobsWrong unit

Reading New Albany’s $178 million payroll equivalent as actual operator payroll.

The city calls $178 million a payroll equivalent: the payroll that would yield the same municipal revenue at a 2% income-tax rate. It is not the operator’s payroll or an employee count.

Inference tested · incentivesOverstated

Reading Ohio’s equipment exemption as meaning qualifying projects pay no taxes.

The state statute authorizes a complete or partial sales-and-use-tax exemption for qualifying equipment. It does not by itself erase payroll withholding, all real-property taxes, local charges or negotiated payments. Net fiscal impact must be rebuilt agreement by agreement.

Relationship tested · powerWrong relationship

Reading Meta’s nuclear agreements as plants directly wired to its New Albany campus.

Meta says its agreements will deliver power to regional grids supporting its operations. The city says New Albany draws from the regional grid. That is different from a dedicated plant or wire serving only the campus.

Projection distinction · jobsProjection, not outcome

Treating Microsoft’s ~50 employees per facility as current observed employment across three sites.

Microsoft projects about 50 employees per facility once operational and says the three facilities are to be operational by the end of 2029. Current construction activity is not observed permanent operating headcount.

Document status · waterDraft, not measured

Treating Ohio EPA’s draft general permit as final blanket permission or proof of actual discharge.

The reviewed Ohio EPA document is a draft general permit. A draft is not a final site authorization, actual discharge or evidence of compliance. Any covered discharge would still face eligibility, effluent and monitoring conditions.

Inference tested · waterEvidence incomplete

Treating New Albany’s no-additional-capacity statement as proof of negligible facility water impact.

The city says data centers have not required additional capacity. That does not disclose facility withdrawals, consumption, discharge, potable/reclaimed shares or peak-day demand. Those remain unknown—not zero.

Published company claim · powerUnverified outcome

Vantage says Millersport will not affect electricity costs for local residents or businesses.

Vantage identifies adjacent natural-gas generation and makes the no-impact claim. Testing it requires final generation, interconnection, backup-power, fuel, transmission and cost-allocation records—not a project page alone.

Open data: Ohio claim checks JSON. A “misleading” or “overstated” verdict does not imply bad faith; it means the wording outruns the cited evidence.

Physical facilities

The older market still counts.

Twenty-nine operator-identified facility or building records across nine providers are included: 21 are current or marketed as available and eight are development/preleasing. These are building/facility IDs—not AI-campus announcements—and several have operated or changed hands for years.

Open data includes every row, candidate queue and current source: Ohio physical-facility JSON. These 29 rows and the 17 project/campus rows are intentionally non-additive.

Major-project first pass

Seventeen projects, with incompatible units left intact.

These rows prioritize current primary or first-party records. A company page can establish what a company claims; it does not independently prove delivery. Open each source directly.

The regulatory ledger

Two records worth watching.

Tariff and incentive rules create future verification hooks. The public value is not merely finding the rule—it is matching each beneficiary’s promise to later compliance records.

Electric tariff · effective 23 July 2025

AEP Ohio Schedule DCT

Applies to new or expanded data-center loads over 25 MW. It includes load-study fees, ramp rules, minimum demand charges, collateral for weaker credits and 100% buildout reimbursement for certain pre-energization cancellation or delay.

Read current tariff guidance ↗
State tax exemption · annual reporting

Ohio Revised Code §122.175

Eligible projects require at least $100 million of capital investment and $1.5 million of annual payroll, with annual reporting of employment, withholding and investment. The hard next step is obtaining agreement- and taxpayer-level reports—not assuming statutory review equals public outcome transparency.
