Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes

Separate site from IREN Sweetwater (Nolan/Fisher County — do not conflate). IREN's Childress page lists 750 MW as the campus's total power capacity, which is not IT capacity (a Baxtel profile says Childress "reached 750 MW operational"; that figure is not adopted here); the AI/Microsoft Horizon 1–4 build-out comprises four 50 MW IT (75 MW gross) liquid-cooled data halls = 200 MW IT total, targeting end-2026 delivery. NewsChannel 10 (May 2026) also reports that IREN will add 100 megawatts of new liquid-cooled data centers and retrofit another 250 megawatts of existing capacity. Horizon 1 (50 MW IT / 75 MW gross) energized Q4 2025 — operational, and IREN announced on August 13, 2026 that Microsoft had accepted it (per the Northwise Project); Horizons 2–4 remain under construction as of mid-2026. Coordinates approximate (county seat area). Site is a 576-acre freehold parcel with on-site 345 kV substations connecting directly to ERCOT. Investment for Horizon 1–4 reported as $300–350M (range; not a firm figure — not recorded as the investment figure). Microsoft contract ($9.7B total, 5-year through ~2031) covers NVIDIA GB300 Blackwell Ultra GPU cloud services; 20% upfront prepayment funded capex. Dell Technologies hardware supply agreement: $5.8B. IREN also holds a separate NVIDIA cloud services contract at Childress. Rack density 130–200 kW per rack; projected PUE 1.05–1.10. IREN Community Grants Program distributes $250,000 annually to the Childress area.

Direct 345 kV grid connection via on-site substations owned by IREN. IREN states it utilizes abundant low-cost renewable energy available on ERCOT and actively curtails consumption during high-demand periods. No on-site gas generation confirmed for this site.
