What the source record says
Two-site campus: Sweetwater 1 (1,400 MW, ~1,700 acres, Nolan/Jones County boundary area) substation energized May 1, 2026 via 345kV ERCOT connection; data centers commissioning in phases. Sweetwater 2 (600 MW, ~500 acres, Fisher County, near Hamlin TX, ~28 miles from SW1) targeted energization late 2027 per IREN (some sources cite 2028). Direct fiber loop planned between sites for single 2 GW compute hub with <10ms latency to Dallas. Coordinates are approximate (Sweetwater city center, Nolan County seat). County boundary sources conflicting: DCD says Fisher County for both sites; interconnection.fyi and dispatch brief cite Nolan County for SW1; northwiseproject.com says Nolan and Jones Counties span the campus. IREN's $9.7B Microsoft contract (Nov 2025) and $3.4B NVIDIA contract (May 2026) are company-wide deals currently deployed at Childress, TX campus (Horizon 1-4); the NVIDIA partnership press release specifically names Sweetwater as the flagship future deployment site for NVIDIA DSX factory architecture. No confirmed customer contracts specific to Sweetwater site as of 2026-07-07. IREN was in Sweetwater since 2022 as a Bitcoin mining site; HPC/AI pivot announced October 2024. Interconnection.fyi lists renewable energy sourcing via RECs (wind/solar) at this site.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
