Opposition and litigation at this site

Nothing on record as of October 9, 2026. No lawsuit, organized opposition, or contested hearing over H5 Data Centers Buffalo III (350 Main Street / Main Place Tower) in Buffalo, Erie County, New York 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

The operator page lists N+1 chillers, N+1 cooling towers and N+1 CRAHs. Classified evaporative because the heat-rejection path includes cooling towers. No water figure is published.

Notes on the record

This is a downtown Buffalo carrier-hotel colocation facility of 19,000 sq ft inside Main Place Tower. The operator lists 21 on-net carriers, 2N UPS and 2N backup generators. PeeringDB notes it is the former Switch & Data / Equinix facility. H5 operates the data center, not the building. The PeeringDB NY registry also lists ixColo and CentriLogic Buffalo (BUF) at 350 Main Street, which makes it a multi-tenant site. No MW figure is published. This site is distinct from colocrossing-buf1-buffalo-ny (325 Delaware Ave) and from the H5 Lockport campus. Coordinates are the PeeringDB geocode.

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

  • 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
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
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
