- July 22, 2026PermittedMicrosoft closed on its ~3,460-acre land purchase (June 26, 2026) and the Cheyenne City Council approved annexation and zoning for the expansion parcel on a 6-3 vote (July 13-14, 2026), clearing the land-use path for the campus; construction has not been reported as begun on this parcel yet. Note: a local referendum petition against the annexation was launched July 20, 2026, so this approval could still be contested. Source: Wyoming Tribune Eagle

Notes on the record
Described by Microsoft as a 'multi-gigawatt multi-decade ecosystem.' The 400 MW initial-target figure that appeared in the prior record was NOT found in either cited source and has been removed pending a citable source (neither the Microsoft newsroom announcement nor Cowboy State Daily mentions a specific MW figure). Separate from existing Cheyenne campus (since 2012) and the HR Ranch Road construction underway 2025-2026. Coordinates approximate for Bison Business Park / SE Cheyenne area.
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
- Permanent jobs promised
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.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Have one of these documents? Send it to us and we will add it to the record with attribution.

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.
