Prometheus Hyperscale has backed out of a planned 1.2GW data center campus near Casper in Natrona County, Wyoming. President Trevor Neilson told WyoFile the company decided not to pursue a project in Natrona or Converse Counties. Natrona County officials said they learned of the decision through media reports. Falls Ranch, the landowner partnership controlled by Texas billionaire Russell Gordy, said work will continue without delay through a new development company.
The 940-acre project, announced in October 2025, was to pair natural gas power from a Spiritus affiliate with carbon capture, and no building permits had been filed. Prometheus said other Wyoming locations offer a clearer path to permitting and community support, while it keeps developing its Evanston campus in Uinta County. Whether the Casper site proceeds now depends on a new developer, and Advance Casper says other developers hold properties under option in the county.
The withdrawal of a developer from a gigawatt-scale US project is a notable reversal. It is a counterpoint to today's flow of new campus announcements.
