What the source record says
Proposed hyperscale campus of nine buildings totaling ~7.1 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. CONFIRMED ABSENCE, re-checked 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 — but neither is a project-stated figure, so capacityMw is intentionally left unset rather than guessed. Site size (549 acres, former Jefferson Proving Grounds Army base, ~8 miles north of Madison, IN) matches the existing record.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
