9. Next steps

ALTA, test wells, and the Palo Duro capacity letter are on the critical path.

9.1Decisions needed now

DecisionByWhy
Confirm BTM rental-gen as first power, owned aero-equivalent + recip as the 350 MW campusNowLocks capex, TTP, and the air-permit story. 100 MW is a tranche.
Freeze 350 MW IT campus / 3 116.667 MW zones / NVIDIA VR200 NVL72 (Vera Rubin) / 415 V / adiabatic-assisted dry plantNowHall count, water legal, and MV architecture already hang on these gates.
Authorize Palo Duro capacity ask and two fiber IRU conversationsNowThe two commercial gates that can kill the site.
Commission the Phase 0 study stack (wells, geotech, H&H, ESA, cultural, ALTA, minerals)Month 0Nothing else is bankable until these return.
Place xfmr/PCU approved-alternates RFQMonth 0–140-week items; none in stock.

9.5After close

Quotes, a sealed power study, and the Palo Duro letter replace the Class 4 bands in this study. Until then the sensitivity in §4.4 is the range.
