IREN Limited’s 2GW Sweetwater Hub has been conditionally classified as Base Load in the Electric Reliability Council of Texas (ERCOT) Batch Zero interconnection screening process. The hub comprises Sweetwater 1, with 1,400MW, and Sweetwater 2, with 600MW, and forms part of IREN’s announced more-than-5GW global data center development portfolio. Sweetwater 1’s high-voltage substation was energized on May 1, 2026, enabling construction of 300MW of gross data center capacity targeted for delivery in Q4 2027. ERCOT created Batch Zero to assess large-load projects collectively amid a backlog of interconnection requests, particularly from data center developers. The Base Load classification remains conditional and subject to further verification and approvals. IREN said additional projects in its broader pipeline were also included in Batch Zero but will be added to its announced development portfolio only after relevant grid connection agreements are executed. The company continues to describe itself as a vertically integrated AI Cloud platform serving AI training and inference, with land and grid-connected power across renewable-rich regions in North America, Europe and APAC.
