In brief

What makes it notable.

  1. A direct 1.4 GW substation connected to ERCOT was energized on May 1, 2026, within a 2,000 MW campus plan in Nolan County.
  2. The design follows NVIDIA's DSX architecture with liquid-cooled HGX B300 GPUs, using IREN's in-house air and direct-to-chip liquid cooling.
  3. IREN runs its own vertically integrated AI cloud platform on the site, with full buildout targeted for 2028.
