Evanston, Wyoming, September 8, 2025- Prometheus Hyperscale, the U.S. data-center developer chaired by former BP CEO Bernard Looney, has signed a wind-power agreement to anchor its flagship hyperscale campus near Evanston, Wyoming. The USD 10 billion development, designed for 1-1.2 gigawatts of capacity, is slated to come online in phases beginning in 2025-26 and aims to demonstrate a new model for powering AI infrastructure with sustainable energy.
The agreement will draw on Wyoming’s abundant wind resources, paired with solar generation, long-duration battery systems, and carefully managed natural-gas backup. Prometheus says this layered approach will ensure reliability while insulating local power prices from the volatility often associated with energy-hungry AI data centers. The company has also outlined carbon-removal and sequestration partnerships to offset emissions from gas-fired dispatchable generation.
Looney, who stepped down from BP in September 2023 and became Prometheus chairman in late 2024, has positioned the project as part of his pivot from fossil fuels to sustainable infrastructure. “We must work to find solutions that lead to Net Positive AI, where the benefits to our world outweigh any costs,” he said when taking on the role. His industry stature and experience managing complex energy deals are seen as critical assets for the ambitious build.
The Evanston facility represents one of the largest single-site AI data center initiatives in North America. Alongside renewable integration, Prometheus is trialing lithium-free, organic flow battery systems to provide long-duration storage, smoothing renewable variability, and reinforcing grid stability. Analysts say this configuration reflects an emerging template for hyperscale AI campuses: co-locating computing with abundant renewables and embedding advanced storage to balance round-the-clock demand.
Wyoming’s wide-open geography and strong wind profile have attracted both energy and data infrastructure developers in recent years, but Prometheus’s 1-GW scale and integrated energy strategy distinguish it from its peers. Industry observers note that if successful, the project could validate a “net-zero-aware” model for hyperscale expansion, delivering AI capacity without overburdening local grids.
With construction scheduled to begin imminently, the company faces scrutiny over execution timelines and whether its blend of wind, storage, and carbon management can deliver at scale. Still, the project underscores the growing convergence of clean energy and AI infrastructure, and marks a notable chapter in Looney’s evolution from oil executive to champion of sustainable digital growth.
