Childress Data Center

IREN developed this Childress campus first for bitcoin mining and is now adding liquid cooled buildings for artificial intelligence. Recent filings separate the site's grid capacity from operating data center capacity and from the smaller information technology load delivered to Microsoft.

What changes the reading

  • The owner and occupant names in the registry are IREN subsidiaries. The subsidiary filing establishes the corporate link while preserving the state record's legal entities.[1][2]
  • Site power capacity, operating data center capacity and information technology load measure different layers. They should not be added or treated as competing versions of one figure.[4][5]
  • The campus began with bitcoin mining. Delivery of the first Horizon building establishes the artificial intelligence expansion but does not show that the whole campus has changed use.[4][5]
  • Microsoft accepted the first planned Horizon deployment. The other announced deployments remain schedule statements until later filings confirm delivery.[5]

Still not public

  • Current mining capacity after the artificial intelligence conversion is not public.
  • Delivery state of the remaining Horizon buildings has not been confirmed.
  • The physical boundaries between mining and artificial intelligence areas are not public.
  • Measured water use and cooling demand are not public.
  • Current metered grid demand is not public.
