Provider notes
Energy. 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.
Community. Hilliard has asked AEP and Bloom Energy to install carbon-capture technology, citing an air permit that allows emissions of up to 1.45 million pounds of CO2 per day, and the air permit is in administrative-court litigation. The array sits adjacent to an elementary school and a neighborhood park.
What the source record says
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).
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
Status history supplied by the source
- 2026 · source-reported 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.
- 2026-07-19 · source-reported operational
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.
Sources and attribution
These sources are listed for the whole row. Unless a figure links to its own source, the provider does not mark which one gave it, so a figure may not appear in every source.
