Opposition and litigation at this site

Nothing on record as of September 21, 2026. No lawsuit, organized opposition, or contested hearing over Chestnut River Holyoke Data Center (former Hampden Papers complex) in Holyoke, Hampden County, Massachusetts appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.

Notes on the record

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.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

Tax abatements or other public subsidy
Permanent jobs promised
Land area
How the community has received it
Which utility serves it

Which document closes each gap

Tax abatements or other public subsidy: The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised: The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Land area: The rezoning application, the plat, or the deed recorded with the county.
How the community has received it: Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Which utility serves it: The electric service agreement or the utility's filing with the state public utility commission.

Have one of these documents? Send it to us and we will add it to the record with attribution.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
