Opposition and litigation at this site

Nothing on record as of September 21, 2026. No lawsuit, organized opposition, or contested hearing over QTS East Windsor in East Windsor, Mercer County, New Jersey 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.

A new status, a permit, a reception finding, or a lawsuit. Nothing else, ever.

Power and water

QTS describes a 50-acre, 14 MW net-metered on-site solar field, 'one of the largest privately-owned, net-metered solar projects in the Western hemisphere', alongside grid supply.

QTS states the site uses a 'closed-loop cooling system that does not consume water for cooling, once operational', with heat exchangers providing full free cooling and mixed-mode free cooling.

Notes on the record

52-acre campus with 70 MW+ critical power capacity. QTS states plans for long-term operations in East Windsor plus one additional data center on the site, described as a further $600 million QTS investment, that figure is for the planned future building, not this facility, so it is not recorded as investmentUsd. Coordinates are the operator-supplied registry point; no parcel-level geocode is published for the street address.

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
  • 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.
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.

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.
