Tenant
CoreWeave was anchor (250 MW, 15-yr lease, 500 MW reserved): exit reported Apr 2026 (MLQ); Jun/Jul 2026 county reports still list CoreWeave as anchor with 40k+ GB300s, unreconciled
Power detail
2 GW planned in eight 250 MW phases; first phase 250 MW (was expandable to 750 MW with CoreWeave); initial 576 MW BTM gas facility reported under construction (Jul 2026)
Power source
Behind-the-meter Permian Basin natural gas; aero-derivative turbines with SCR emissions controls; battery storage + grid interconnect for backup only
Cooling
Closed-loop liquid-to-chip (sealed loop); process water from non-potable groundwater: no draw on Fort Stockton municipal supply
Compute
40,000+ Nvidia GB300 NVL72 GPUs were to come via CoreWeave from Dec 2025
Construction start
Oct 2025 (ground broke)
Est. completion
Originally Q1 2027 (phase 1): now uncertain; Jul 2026 county report still targets late 2026/2027
