Behind-the-meter, dual-fuel generation designed to support up to 1.5 GW of data hall capacity in Phase 1, with first power targeted for 2027
Reeves County, Texas - August 20, 2026 – Prometheus Hyperscale and Istmo Energy today announced plans to jointly develop a hyperscale data center campus in Reeves County, Texas. The Pecos campus is designed to deliver 1.5 GW of compute capacity in Phase 1, with a defined path to 2.5 GW.
The West Texas site brings together the attributes hyperscale customers are seeking: large-scale near-term power, fuel redundancy, fiber connectivity, uptime reliability, and a development path designed to shorten the time between commitment and compute.
Designed to operate behind-the-meter with on-site generation, the Pecos campus is not dependent upon waiting for grid interconnection or transmission upgrades enabling a compressed time to compute and an ability to deliver capacity that meets the market demand. Future tenant-directed grid connectivity is possible.
The campus will generate power from both pipeline natural gas and ethane from Istmo Midstream’s co-located fractionation facility. The dual-fuel architecture provides an additional layer of fuel security and operational flexibility by reducing dependence on any single fuel source or supply pathway, while providing the reliability and resilience required for continuous compute.
First power is targeted for 2027 using modular data center construction, with the option to combine with custom built facilities in 2028.
The campus will use closed-loop cooling, meaning it recirculates the same cooling solution internally. It is not evaporative and operates without drawing from or discharging to local water supplies.
“The Pecos Project and partnership with Istmo Energy adds 2.5GW to our existing project pipeline and advances our vision of developing scalable infrastructure for the age of AI," said Trevor Neilson, President of Prometheus Hyperscale. "It demonstrates the strength of our energy-first approach: starting with reliable, redundant power and building from there to deliver speed, scale, and flexibility for hyperscale customers. We look forward to developing this project alongside the Pecos community and working together to maximize the benefits it delivers locally.”
"Power availability and long-term reliability have become the primary bottlenecks for the AI transition," said Alex Gutierrez, CEO of Istmo. "By pairing behind-the-meter generation directly with our co-located fractionation assets, we are delivering a unique and unprecedented dual-fuel capability in behind the meter data centers. Seamlessly integrating on-site ethane supply alongside pipeline natural gas eliminates single-point fuel risks, insulates compute from grid constraints and curtailments, and establishes a new benchmark for uptime and operational resilience in hyperscale infrastructure."
