What is established
Under construction. 2 GW announced (critical it load); owned or developed by IREN.
What is not disclosed
Accelerator count, hardware platform, project capex, timeline, named tenant, power source, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
Energization is the high-voltage substation connection to ERCOT, not operating IT capacity: 'Power delivery at Sweetwater 1 is expected to ramp progressively in line with the phased construction and commissioning of data centers.' Sweetwater 2 (600MW, ~28 miles away) targeted late 2027; the two sites are to be fiber-linked into a single 2GW hub. Coordinates approximate (town of Sweetwater).
Physical work is under way and the evidence includes a primary source.
Power readiness
Capacity basis stated
The source distinguishes IT load from total site power or on-site generation.
Derived from the evidence on this page by a published rule, not a model. How this is calculated.
