Opposition and litigation at this site
Nothing on record as of September 14, 2026. No lawsuit, organized opposition, or contested hearing over Ptolemy Data Systems Sheridan Data Center in Sheridan, Sheridan County, Wyoming appears in the sources this registry tracks.

Notes on the record
Ptolemy's own capability document states it constructed a 6,000 sq ft data center in Sheridan in 2012, including a 1,024 sq ft concrete-and-steel "data vault" on 480V three-phase power with racks supporting up to 15,000 W each, in-row chilling towers, APC Symmetra UPS and a 0.5 MW Generac generator with 30 hours of on-site fuel. Colocation directories list the address as 2910 Russell Drive; that address is not confirmed in a primary source, so only the street-level geocode is recorded and no street field is asserted. No facility-wide MW rating is published (the 0.5 MW figure is standby generation, not IT capacity).
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.
- Power capacity in megawatts
- Cooling method and water use
- 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.
- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- 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.
