Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Under construction
In active litigation over a 228-unit Bloom Energy fuel-cell array (73MW, largest fuel-cell array in North America) plus backup generators; approved by the Ohio Power Siting Board under HB15.
Underlying source - Operational
Status changed from under construction to 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.

Source notes
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).
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. Ohio Power Siting Board approval 2025-09-22; construction began January 2026; in service expected September 2027.
