US data center firm Prometheus Hyperscale has dropped out of a planned data center project near Casper in Natrona County, Wyoming.

Company Confirms Withdrawal from Natrona County Campus

The announcement comes despite the fact that the company was still in discussions with local officials about the project as recently as September and had not yet filed for building permits.

"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.

The Planned Gigawatt-Scale Campus

Plans for the 1.2 GW site were announced in October 2025, with Prometheus set to work alongside Spiritus and Casper Carbon Capture. The 940-acre site was set to include natural gas power from Spiritus affiliate Orchard Power and carbon capture from Casper Carbon Capture. The first phase of the project was originally due to come online this year.

As recently as August, Prometheus had announced a potential partnership with Mesa Power Solutions for on-site power generation at the Natrona County campus.

Local Officials Caught Off Guard

Natrona County officials told the press the news took them by surprise, saying they only learned of the cancellation through media reports, and are unsure why the company pulled out.

"I don't see the Natrona County government as being a deciding factor for them to pull out, but I don't know. 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," Natrona County commission chairman Jim Milne told WyoFile.

Justin Farley, CEO of economic development organization Advance Casper, told Oil City News: "Advance Casper is disappointed in their decision to pull out of there. Fortunately, we have other developers that have properties under option in Natrona County. So, we'll continue to work with them. Natrona County is still open for business, and we're still going to pursue any leads that we get in data centers."

Local Opposition Was Limited

A Change.org petition against the project had gathered more than 900 signatures at the time of writing. Though some local residents had voiced opposition to the project at public meetings, there was seemingly no major groundswell against the development, and local officials were generally in favor of the proposals.

The Landowner Says Development Will Go Ahead Without Prometheus

The planned data center may still proceed, however. Falls Ranch, a limited partnership that owns the land and is controlled by Texas billionaire Russell Gordy, has announced that "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, representative for Falls Ranch. "This recent shift will expedite and elevate this project for Natrona County, and we couldn't be more excited about it."

Prometheus's other projects

Launched around 2020 and formally known as Wyoming Hyperscale Whitebox, Prometheus was relaunched in September 2024. The company is still developing its original flagship campus in Evanston, in Wyoming's Uinta County, and has projects in development 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 said.
