Prometheus Hyperscale Evanston campus
Announced
United States · 1 project · Last reported
Summary
Proposed AI data center campus on about 506 acres of family ranchland roughly 12 miles east of Evanston, Wyoming, south of Interstate 80 in Uinta County. Prometheus Hyperscale plans 1.25 GW in a first phase with a stated path to 5 GW, run as an islanded microgrid on on-site natural gas generation rather than the public grid. Uinta County commissioners unanimously granted a conditional use permit in June 2026; the company says construction could start within six months of final permitting and take four to five years. The county sent support letters to Meta and Microsoft, but no tenant has been confirmed.

| Measure | Value | Scope | As of | Notes | Sources |
|---|---|---|---|---|---|
| Power capacity | 1,250 MW | Planned · Phase · Unspecified · Initial phase | 2026-06-22 | Described as the initial capacity, with the first phase expected to take 48 to 60 months to build. Cowboy State Daily rounded it to 1.2 GW in February 2026. IT versus facility scope is not stated. | KPCW; Baxtel; Cowboy State Daily |
| Power capacity | up to 5,000 MW | Planned · Campus · Unspecified | 2026-06-22 | Company-stated long-term development path; no schedule given. | Baxtel |
| Land area | about 506 acres | Reported · Campus | 2026-06-19 | Ranchland held by the founder's family. | KPCW; TownLift; Baxtel |
| Jobs construction | 1,500–2,000 count | Reported · Campus | 2026-02-14 | Estimate given by the county economic development director. | Cowboy State Daily |
| Jobs construction | about 8,000 count | Planned · Campus | 2026-06-22 | Construction positions by 2029 claimed by Prometheus and the Build Wyoming initiative, within a total of nearly 12,000 direct and indirect jobs. Much higher than the county's February 2026 estimate. | TownLift |

Timeline
| Date | Event | Actual or planned | Notes | Sources |
|---|---|---|---|---|
| 2024 | Announced | Actual | The project, formerly called Wyoming Hyperscale Whitebox, was relaunched in 2024 after an original 120 MW plan in 2020. | Baxtel |
| 2026-02 | Other | Actual | Uinta County approved letters of support addressed to Meta and Microsoft, written at the developer's request. | Cowboy State Daily |
| 2026-06 | Permit approved | Actual | Uinta County commissioners unanimously approved a conditional use permit after the county planning commission recommended approval; reported on 19 June 2026 as a Tuesday vote. | KPCW; Baxtel |
Power supply
| Type | Description | Sources |
|---|---|---|
| Natural gas onsite | Planned on-site natural gas generation run as an islanded microgrid instead of a grid interconnection, which the company says avoids interconnection delays. The founder has said he eventually wants to add nuclear power. | KPCW; TownLift; Baxtel |
Meta and Microsoft are not listed as tenants: the county's support letters were written at the developer's request, and in February 2026 the county chair said any deal was a long way off. Prometheus says its closed-loop water-glycol cooling will not draw groundwater, surface water or Bear River water, with a private on-site well for domestic plumbing. No report of final permitting or a construction start after June 2026 was found.

Evidence
Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
