Prometheus Hyperscale Pulls Out of 1.2GW Casper, Wyoming Data Center

Prometheus Hyperscale has abandoned a planned 1.2GW data center campus near Casper, Wyoming, less than a year after announcing it. The 940-acre site in Natrona County isn't dead, though — the landowner says work continues under a new development company.

"After spending a great deal of time evaluating the opportunity, we have decided to not pursue a data center project in Natrona or Converse Counties," Prometheus Hyperscale president Trevor Neilson told WyoFile. Casper Star Tribune and other local outlets confirmed the withdrawal.

For practitioners, the message is blunt: a gigawatt-scale commitment announced in October 2025 is gone before a single building permit was filed. The company was still in discussions with local officials as recently as September.

What was planned at the Casper site?

The project had three named partners and an energy strategy built around gas:

• Spiritus, with affiliate Orchard Power supplying natural gas generation on site
• Casper Carbon Capture, handling carbon capture for the campus
• A first phase originally slated to come online this year

In August, Prometheus had also flagged a potential partnership with Mesa Power Solutions for on-site power generation at the Natrona County campus. None of it moved to permits.

How did local officials react?

Badly — and late. Natrona County officials say they learned of the cancellation through media reports, not from the company, and they don't know the reason for the pullout.

"I don't see the Natrona County government as being a deciding factor for them to pull out, but I don't know," commission chairman Jim Milne told WyoFile. "I'm just kind of disappointed, and I'd highly encourage them to reconsider if they have a future project or change their minds and reconsider Natrona County."

Justin Farley, CEO of economic development group Advance Casper, told Oil City News the county has alternatives. "Fortunately, we have other developers that have properties under option in Natrona County," Farley said. "Natrona County is still open for business, and we're still going to pursue any leads that we get in data centers."

Local opposition existed but looked modest. A Change.org petition against the project had gathered more than 900 signatures at time of writing, and some residents objected at public meetings. Local officials, by contrast, were generally in favor — so community resistance doesn't obviously explain the exit.

Will the data center still get built?

Probably, just without Prometheus. Falls Ranch, the limited partnership that owns the land and is controlled by Texas billionaire Russell Gordy, says "work will continue without delay" through a new development company.

"This has always been a Wyoming project, but today it represents something even greater: an opportunity for Natrona County to shape its own economic future," said Robert Hand, Falls Ranch's representative. "This recent shift will expedite and elevate this project for Natrona County, and we couldn't be more excited about it."

Where does Prometheus go from here?

The company isn't exiting Wyoming entirely. Launched around 2020 and formally known as Wyoming Hyperscale Whitebox, it relaunched as Prometheus in September 2024 and is still developing its flagship campus in Evanston, Uinta County, plus projects in Dallas and Reeves County, Texas.

"We are thrilled with our progress in Evanston with Uinta County and believe other additional locations in Wyoming offer a clearer path to permitting and community support," Neilson told press.

That framing suggests permitting friction, not demand, drove the decision — a signal worth watching for anyone siting large campuses in the state. DCD has reached out to Prometheus for comment.
