Power and water

Direct 345 kV grid connection via on-site substations owned by IREN. IREN states it utilizes abundant low-cost renewable energy available on ERCOT and actively curtails consumption during high-demand periods. No on-site gas generation confirmed for this site.

Direct-to-chip closed-loop liquid cooling. IREN states the system does not consume water on an ongoing basis; annual top-ups require roughly as much water as a few houses. Water is trucked in externally, deliberately not drawn from Childress municipal supply. System described as analogous to a vehicle radiator.
