Why it matters
The strategic read
Adds a primary-backed, gigawatt-scale West Texas campus built around power availability rather than a conventional grid interconnection. Prometheus and Istmo are pairing modular data-center construction with on-site natural-gas and ethane generation, a dual-fuel design intended to reduce both grid-delay and single-fuel risk while targeting first power in 2027.
Source-supported terms
What was disclosed
- 01
Prometheus Hyperscale and Istmo Energy announced plans to jointly develop the Pecos campus in Reeves County, Texas.
- 02
Phase 1 is designed for 1.5 GW of compute capacity, with a defined expansion path to 2.5 GW.
- 03
The campus is designed to operate behind the meter rather than wait for grid interconnection or transmission upgrades.
- 04
On-site generation will use both pipeline natural gas and ethane supplied by Istmo Midstream's co-located fractionation facility.
- 05
First power is targeted for 2027 through modular construction, with an option for custom-built facilities in 2028.
- 06
The closed-loop cooling system is described as non-evaporative and designed to avoid drawing from or discharging to local water supplies.
Disclosure boundary
What is known—and what is not
Joint development plan announced by Prometheus Hyperscale and Istmo Energy. The primary release identifies the Reeves County site, 1.5-GW first-phase design, 2.5-GW expansion path, dual-fuel behind-the-meter generation concept, closed-loop cooling posture and first-power target.
