Former bitcoin mine in West Texas converted for AI/HPC. Phase I (~200 MW gross, 133 MW critical IT) delivered to CoreWeave on a 15-year lease; CoreWeave has committed to 526 MW of critical IT across Phases I–III (the 800 MW of gross power first approved). Planned figure is Galaxy’s total approved power capacity (ERCOT approved a further 830 MW in Jan 2026), not contracted IT load; Galaxy cites potential to scale to as much as 3.6 GW.
Current and planned figures may use different power bases. Planned power is the end state, not additional capacity to add to the current figure. An unspecified basis remains unknown. A figure marked est rests on at least one source other than the operator’s own announcement.
