IREN Energizes 1.4GW Sweetwater 1 Substation, Advancing 2GW Campus
IREN connected its 1.4GW Sweetwater 1 data center substation to ERCOT, marking a key milestone toward the 2GW Sweetwater campus. Power delivery at Sweetwater 1 will ramp progressively with phased construction, enhancing grid-connected capacity for AI infrastructure.
1. Substation Energization Milestone
IREN successfully connected its high-voltage substation at Sweetwater 1 to ERCOT, energizing the 1.4GW facility. This achievement follows scheduled timelines and confirms electrical readiness for data center commissioning.
2. Capacity Ramp and Phasing
Power delivery will ramp up progressively as successive data halls come online, aligning with the broader 2GW Sweetwater campus development. This phased approach manages load integration and ensures stable grid operations.
3. Strategic AI Infrastructure Impact
Grid-connected capacity reduces AI compute latency by delivering power at scale and supporting large-scale training workloads. The milestone underscores IREN’s vertically integrated model and bolsters its position in the competitive AI cloud market.
