C. Equipment summary

  • 1,844 × NVIDIA VR200 NVL72 (Vera Rubin) (190/190/230 kW) across 3 × 117 MW zones
  • 16 × GE Vernova LM2500XPRESS+G4 DLE at 26.42 MW site rating (34.5 MW ISO, 23.4% derate) · 422.7 MW gross / 396.2 MW firm N+1 · 3 collector sections
  • 151 × CoolIT CHx2000 CDU at 2,269 kW (150 duty + 1 standby)
  • 351 × Güntner V-shape VARIO GFD with hydroBLU, 24 fan at 3,299.8 kW (319 duty + 32 spare), 28 MW of fans
  • 140 MW / 75 MWh grid-forming BESS in 15 containers on 0.5 ac
  • 160 × 3,750 kVA padmount · 372 × Schneider Galaxy VXL 1,250 kW
  • Graph: 3,127 nodes, 3,644 circuits

NVIDIA rebranded NVL144 to VR200 NVL72: 72 Rubin GPU packages at 2,300 W each, 36 Vera CPUs. ~190 kW Max Q, ~230 kW Max P; TrendForce puts the shipping rack near 225 kW. Compute and NVSwitch trays are fanless, so essentially all of it lands in the coolant, and coolant flow is roughly double GB300. NVIDIA specifies 45 C liquid supply, which is what makes dry-side rejection work in West Texas. Standard in-rack PSUs at this generation; 800 VDC is optional and does not become the norm until Kyber. MGX rack contributed to OCP

D. Assumptions register

Frozen decisions first, then every default still marked Estimate or Selected. Outstanding items follow.

DecisionValue
facility_it_mw
Authoritative campus gate. Hall count and rack count are computed from this, never the reverse. 100–133 MW IT is Phase 1 first-power on Palo Duro, a tranche of this campus, not the project. Phase 3 is the 345 kV cut-in of that campus. Phase 4 toward 3 GW is corridor optionality, not this compile (Galaxy already holds 1.6 GW on the node).
350Constraint
first_power_it_mw
First fire / first vest. Not the campus headline. Palo Duro nameplate caps BTM first power around 125–150 MW, not 350 MW.
100Plan
collector_sections
One 34.5 kV bus cannot carry 350 MW: machine contribution exceeds catalog MV interrupting ratings. 3 independent sections keep first-cycle duty in 63 kA gear. Losing one drops about 33% of IT. Not Uptime Tier III (no closed ties).
3Selected
hardware_profile
The plan names no GPU SKU. NVIDIA VR200 NVL72 (Vera Rubin) is the current high-density reference with published integrator ratings: planning 190 kW, peak 230 kW. Compute and NVSwitch trays are fanless, so 97% of rack heat leaves in coolant at a 45 C supply, which is the property that makes dry-side rejection viable here. main.tex golden fixture (GB200 NVL36x2 at 67 kW) is a 5 MW math test, not this campus.
vr_nvl72Selected
delivery_voltage_v
415Y/240 V AC three-phase. 800 VDC path is specified in main.tex but deferred: product standards for >1 kV DC in buildings are immature.
415Constraint
redundancy
Unit N+1 with a transfer-capable reserve per fleet. 2N is a later leaf.
n1Selected
distribution
Radial 415 VAC. Rings lose Farivar–Low exactness; not this pass.
radialSelected
source_mode
Phase 1 has no utility. Grid interconnection is Phase 3 (queue frozen Aug 3, 2026; first utility MW P50 mid-2030).
islandPlan
cooling
Fully dry / air-cooled / closed-loop as basis of design. Evaporative cooling is a closed option, not a slider. β_dry = 1.0.
air_cooledPlan
code_editions
King County has no building department (LGC Ch. 233). Insurer standards (FM 1-28, 1-34, 4470) are the de-facto envelope. Changing this field re-keys the check register.

phase1_pad_acres_program
Program acreage of the West Big Field pad (first-power tranche). Construction footprint across the first tranche is ~1,200 ac. Not the campus lot.

773Record
generation_phase1
First-power block only. Conflict resolved: Phase 1 narrative says rented 16 MW truck units; element detail says 6 × LM2500XPRESS-class. Electrical first-fire model is this 6-unit block. Not the campus fleet.

generation_campus
Campus electrical model is one machine class at the same firm MW as Atlas P2 (6 × LM2500XPRESS + Wärtsilä/Jenbacher recip halls). Physical conversion is a later leaf.

bess_phase1
First-power storage. Not the campus spec.

bess_campus
Campus storage. Atlas P2 +100 MW is the program add; NVIDIA VR200 NVL72 (Vera Rubin) peak at 350 MW IT sets the spec.
{"mw":280,"mwh":125}Calculated
tceq_standard_permit_ceiling_mw
Phase 1 207 MW gross sits under the ~360 MW TCEQ standard-permit ceiling. Campus 724.5 MW gross is well above it, so case-by-case NSR sits on the Phase 2 critical path, not a later nice-to-have.
360Record
estimate_class
Class 4 (−30% / +50%). Tightens to Class 3 once sealed studies return. Conductor-and-busway dollar totals from the compiler catalog are not used as the project capex figure; see BOM notes.
4Selected
wue_basis
Air-cooled campus demand basis ~80–270 AF/yr per 100 MW (humidification, domestic, washdown). Evaporative 800–1,500 AF/yr per 100 MW is not supportable against King County MAG of 49 AF/yr.

G. Glossary

TermMeaning in this report
IT MWInformation-technology load at the rack. The hard gate in this design is the 350 MW Phase 2 campus (3 116.667 MW zones). First power is 100 MW, a tranche, not the project. Halls and racks are computed from this, never the reverse.
Facility MWIT after conversion loss, plus mechanical, plus house, at the 34.5 kV collectors. This run is in the compiler dump (headline.facility_mw).
PUEPower usage effectiveness: total facility energy / IT energy. This run: 1.064, of which 1.018 is the mechanical plant. Not a contractual guarantee.
WUEWater usage effectiveness (The Green Grid WP#35), liters per kWh IT. This run: 0.05 L/kWh, 116 AF/yr, from the 4.1% of hours the coolers need adiabatic assist.
Time to power (TTP)Months from option day. Reported as two distributions: first 100 MW IT, and 350 MW campus live. P10/P50/P90, not a date.
BTMBehind-the-meter: on-site generation, no utility interconnection required to run.
Ω_buildBuildable area: parcel minus the union of exclusion polygons (title, pipeline, wells, WOTUS, cultural, acoustic, FAA).
AACE Class 4Estimate class entitled to −30% / +50% (18R-97). Not a bid.
run_idHash of the sorted JSON payload. Every number on this site came from one solve with this stamp.
N+1One spare unit per fleet, transfer-capable. 3 independent 34.5 kV sections: losing one drops ~33% of IT. Not Uptime Tier III.
Fit-classmain.tex A differentiable / G geometric / B scenario / D documentary / X procured licensed study. Printed in Appendix I. Not a claim that this design implemented every A-class vjp.
MAGModeled available groundwater. King County Blaine: 49 AF/yr (TWDB GAM Run 21-011).
NVIDIA VR200 NVL72 (Vera Rubin)NVIDIA rack-scale GPU system. Planning 190 kW, peak 230 kW. Compute and NVSwitch trays are fanless, so 97% of rack heat leaves in coolant at a 45 C supply.
LM2500XPRESSAeroderivative gas turbine class, 34.5 MW each in this design. First power: six units, 207 MW gross / 172.5 MW firm N+1. Campus electrical model: 21 aero-equivalent units, 724.5 MW gross / 690 MW firm; Atlas P2 physical plant is aero + recip halls at the same firm MW.
JETITexas Jobs, Energy, Technology and Innovation Act (HB 5). Covers dispatchable generation and manufacturing; renewable generation and storage are excluded.
CUECarbon usage effectiveness (The Green Grid): kg CO2 per kWh IT. This run is a heat-rate × EPA NG emission-factor sketch, not a contractual 24/7 CFE number.
D01–D07Documentary checks from main.tex Appendix L. Separate from electrical C01–C26. D01 is the completeness fixture.
