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.

Reported lifecycle history

  1. Proposed

    Jan 21, 2025 IREN business update: first formal public announcement of 1,400 MW Sweetwater data center development. October 2024 update had disclosed HPC/AI pivot on 1,300+ acres.

    Underlying source

Source notes

Two-site campus: Sweetwater 1 (1,400 MW, ~1,700 acres) 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). As of October 2026, the county is not settled by the cited pages: Data Center Dynamics places both sites outside Sweetwater in Fisher County, and no cited page that names IREN places Sweetwater 1 in Nolan or Jones County. 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.

345kV high-voltage connection to ERCOT grid. IREN and third-party sources describe West Texas as one of the world's largest renewable energy markets.
