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.

Source notes
Proposed hyperscale campus of nine buildings totaling ~7.2 million sq ft on 549 acres of the former Jefferson Proving Ground airfield, on land owned by the Ford family (Daniel Ford); the end-user/operator has not been publicly disclosed. Reported to draw hundreds of megawatts and be roughly 78% larger than Meta's Lebanon campus; projected 300-450 permanent jobs and ~$60M in annual county tax revenue. Coordinates are an approximate geocode of the former proving-ground airfield north of Madison. As of 2026-09-10, no official capacity, utility partner, or anchor-company figure has been released for this site. Independent, unofficial estimates cited in the same article range widely: one expert (Chien) says 9 GW 'is not unreasonable' for a power-dense AI training facility, while another (Inskeep) is 'very confident' it will need at least 1 GW. Neither is a project-stated figure, so no capacity is recorded. The site is 549 acres of the former Jefferson Proving Grounds Army base, ~8 miles north of Madison, IN.
