    Operating
    Flipped under_construction -> operational. Franklin County Auditor assessed building area is populated (880,352 sq ft) on the campus parcel (050-011455, land-use class 'data center', Amazon Data Services Inc) = built, not a bare shell; data-center directories (DC Byte / datacenterHawk) list the Cosgray buildings as operational. The Bloom Energy fuel-cell / backup-generator permitting litigation noted in the record concerns on-site power and does not bear on the data buildings' operational status.

Power and water

228 Bloom Energy solid-oxide fuel cell units totalling 72.9 MW, to be built and operated behind the meter by Ohio Power Company (an AEP Ohio subsidiary) on about 6.4 acres at 4186 Scioto Darby Creek Road, serving Amazon Data Services only and not exporting to the grid.

Notes on the record

Separate AWS Hilliard campus on Cosgray Road, in active litigation: the City of Hilliard appealed an Ohio EPA air permit for a 228-unit Bloom Energy fuel-cell array (73MW, the largest fuel-cell array in North America), and AWS is separately seeking a permit for 158 diesel backup generators. Approved by the Ohio Power Siting Board under Ohio's HB15 behind-the-meter law, overriding local zoning. Distinct from the Scioto Darby campus. Coordinates are now parcel-exact via the Franklin County Auditor (parcel 050-011455, 4580-4640 Cosgray Rd, Amazon Data Services Inc, data-center use class, ~95 ac).

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Power capacity in megawatts
  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • Land area
Which document closes each gap
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Land area
The rezoning application, the plat, or the deed recorded with the county.
