Provider notes
Community. Trenton Planning Commission approved the site plan in a ~10-minute meeting (Mar 30, 2026) taking no public questions despite ~30 residents expecting a hearing; a 500+-member opposition group (W.A.T.E.R.) is petitioning for a Butler County charter amendment to ban data centers over 25MW.
These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.
- Cooling: Previously held pending provider-field review. The concern has not been resolved by an independent source review for this captured edition; the field remains withheld.
What the source record says
Project Mila in Trenton, Butler County (outside Cincinnati): four 220,000 sq ft single-story buildings (880k sq ft total) plus an on-site substation. Planning approved March 2026; construction from fall 2026. Estimated ~100-200 MW (not officially disclosed — omitted from capacity). Distinct from Prologis's Newnan, GA campus. Coordinates are the Trenton area centroid.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
