IREN Sweetwater

Project details

Capacity 2000 MW reported. Status planned. City . County Nolan. State TX. Grid ERCOT.

Overview

IREN’s Sweetwater page describes a 2,000 MW AI campus in West Texas across two sites, Sweetwater 1 and Sweetwater 2, on 2,200 acres capable of supporting more than 700,000 liquid-cooled GPUs. IREN says both sites connect directly to the ERCOT grid with multiple fiber paths and less than 10 ms latency to the nearest hyperscaler regions, and lists air plus liquid cooling. Sweetwater 1 is listed at 1,400 MW on 1,700 acres, under construction, with 2026 substation energization. Sweetwater 2 is listed at 600 MW on 500 acres, under construction, with 2027 substation energization. Procurement and site works are underway to support energization of the 1,400 MW bulk substation (345 kV/138 kV) as well as primary substations (138 kV/34.5 kV) at Sweetwater 1. Data Center Map catalogs IREN Sweetwater 1 at 883 Farm-to-Market 611 in Sweetwater, Texas. The public map’s two planned halls match IREN’s 1,400 MW and 600 MW site split. IREN frames the two-site hub as AI Cloud capacity with a direct ERCOT grid connection rather than a behind-the-meter mining retrofit. Nolan County, Texas, has no other campus in this directory.

The public map lists 2 map records. Reported campus capacity is 2,000 MW. All 2 buildings are planned.
