Prometheus Hyperscale Wyoming: $30B 2.5GW Bernard Looney AI Hub
Status: Operational / Rapid Expansion (April 2026) | Location: Evanston & Casper, Wyoming
Project Overview
Prometheus Hyperscale represents a significant evolution in the integration of energy systems and large-scale AI compute, led by Bernard Looney. Announced in March 2026 as a consolidated $30 billion initiative, the project spans two major campuses in Evanston and Casper, positioning itself at the forefront of next-generation, energy-integrated hyperscale infrastructure. The development is explicitly designed to address one of the most critical constraints in AI expansion: the alignment of reliable, scalable power with ultra-high-density compute environments.
Technically, Prometheus Hyperscale is pioneering a new model built on geothermal cooling and advanced liquid heat transfer systems. The architecture leverages proprietary underground heat sequestration techniques, enabling the facility to operate with zero external water consumption for cooling—an industry-first claim at hyperscale in the United States. This approach not only mitigates water scarcity concerns but also enhances long-term thermal efficiency for continuous AI workloads. The flagship Evanston campus is particularly notable, spanning approximately one square mile of data halls within a vast 12,000-acre ranch, designed to accommodate extreme rack densities and future multi-gigawatt expansion.
