Proposed-site record

Sweetwater 1 and 2

IREN's Sweetwater 1 substation is energized, but the company says only 300 MW gross of data-center construction is continuing at that site; Sweetwater 2 remains a separate 600 MW development. The dataset's 2,000 MW is retained as planned campus power context, with facility IT load, water, wastewater, customer allocation, and public money unresolved.

Compute Workload

This panel tracks what the facility is for without assuming that every project is AI training, inference, or cloud capacity.

Undisclosed / unknownUnknown

No source-backed workload, customer, hardware, or training/inference allocation is attached to this record yet.

Workload classification remains unknown in the reviewed record.

Data Fields

Public Money

No public funding record attached yet. Local subsidy, tax-abatement, land, bond, and utility records need follow-up.

Water

Source reviewed September 9, 2026: IREN describes air plus liquid cooling at Sweetwater 1 and 2, but the reviewed company and SEC materials do not publish a facility withdrawal, consumption, water right, or wastewater-service quantity. Preserve water use as unresolved.

Power

Source reviewed September 9, 2026: IREN separates Sweetwater 1's 1,400 MW high-voltage substation from the 300 MW gross data-center construction target and says the substation was energized in May 2026; Sweetwater 2 is a separate 600 MW site with conditional ERCOT Batch Zero inclusion and future energization. The 2,000 MW total is planned high-voltage campus capacity, not confirmed energized or IT-load capacity.

No fuel-cell or Bloom Energy source is attached to this project yet.
