How the community has taken it

Reception is a sourced signal, not an editorial judgment: mixed reception means documented support and documented opposition both exist with no clear majority position on record.

Power and water

Cheyenne Power Hub natural-gas plant (Tallgrass), scalable toward multi-GW; Black Hills Energy co-invested.

Closed-loop cooling systems recirculating treated water; plans include deep wells beneath the Lance Formation to reach industrial water below the Ogallala Aquifer. Wastewater treatment is to occur on site with evaporative lagoon storage, which is disposal rather than the heat-rejection method.

Notes on the record

Switchgrass Industrial Park, Hwy 85 south of Cheyenne, Laramie County - geographically distinct from Meta (Project Cosmo) and Microsoft's Cheyenne campuses. 716-acre campus. Originally announced at 1.8GW as 'Project Jade' with an undisclosed hyperscale client (Crusoe Energy as builder); Crusoe exited June 2026. On 2026-07-08, Google was publicly revealed as owner/operator via subsidiary Jupiter Star Holdings, and the project was renamed 'Project Tembo'; capacity confirmed at 2.7GW with an ultimate ceiling of up to 10GW. The Cheyenne Power Hub on-site natural-gas plant supplies power (Tallgrass Energy; Black Hills Energy co-invested). ~$50B total project figure remains a projection. Completion targeted 2031.

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.

  • Tax abatements or other public subsidy
Which document closes each gap
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.

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.

Questions people ask about this site

Is there opposition to the Project Tembo data center in Cheyenne?

Partly. Both documented support and documented opposition to Project Tembo in Cheyenne, Laramie County, Wyoming appear in the record, with no clear majority position.

Has anyone filed a lawsuit over the Project Tembo data center?

No lawsuit over Project Tembo appears in the record we track as of September 2, 2026. Residents most often reach a lawyer over water supply, well drawdown, noise from cooling plant, property value, or a rezoning approved without the notice the ordinance required. If any of that is happening near this site, it is worth a review whether or not a case has been filed yet.

How much water does Project Tembo use?

No water withdrawal figure for Project Tembo is on record here. Cooling is recorded as closed_loop, which is the strongest available clue: closed loop and air cooled plant draw far less than evaporative cooling. We leave the number blank rather than estimate one.
