Opposition and litigation at this site
Nothing on record as of September 14, 2026. No lawsuit, organized opposition, or contested hearing over ETC DC OpCo Lysite Data Center ("1 MW DC Site") in Lysite, Fremont County, Wyoming 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.
Power and water
Permit application covers eight Mesa Power Solutions GV22 PowerCore natural-gas-fired emergency generator engines rated 604 horsepower each (4,832 hp total), each limited to 100 hours of non-emergency operation per year with non-resettable hour meters, which WDEQ treats as best available control technology.
Notes on the record
Site is about three miles east-northeast of Lysite in unincorporated eastern Fremont County, near the Lost Cabin Gas Plant. The application documents label the project the "1 MW DC Site"; the DEQ analysis does not explain whether that designation is the anticipated electrical demand or another measure, so no capacity is recorded here. Footprint, acreage and water use are not disclosed in available records. Coordinates are a geocode from the published distance-and-bearing description and are not a parcel-confirmed point.
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
