Overview

Grid & water — why here
source: HIFLD · EPAThe closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.

Tax breaks & subsidies
source: Good Jobs First / GASB 77No per-deal tax break is linked to this site yet. No state discloses the recipient of a data-center abatement at the facility level, so per-site deals are rare in the public record. If you have a development agreement or board resolution for this site, send it to us.
Ohio reported $130.4M in Sales/use tax exemption for qualified property used in an eligible computer data center (R.C. § 122.175) for FY2024 (Ohio Department of Taxation / Office of Budget and Management). Program-wide, not attributable to this site.
