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
Status is "proposed", not "cancelled": Holyoke's City Council voted 9-4 on 2026-06-17 to ban AI data centers above 12 MW, which would bar this 20 MW project as designed, but the developer stated "We're not closing the door - and we hope Holyoke won't either" and had neither filed permits nor bought the property. The coordinate is the OSM-mapped former Hampden Paper Co building at the cited address, marked approximate because the proposal covers the wider complex. The 20 MW is the developer's stated figure; $200M is the reported project cost for this site only. Holyoke's ban explicitly exempts the tracked MGHPCC.
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
- 2026-06-16 · source-reported proposed
Boston-based Chestnut River Power and Infrastructure publicly sought the former Hampden Papers complex at 100 Water Street for a 20-megawatt "micro facility"; WAMC reports no permits filed and no property purchased at that point.
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.

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.
