Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Source notes
Adjacent to the 2.5GW Susquehanna Steam Electric Station. FERC blocked a proposed colocation agreement in April 2025, leading to the PPA structure instead. TeraWulf operates a separate Nautilus cryptomining facility (Nautilus) on the same property not included in this record.
10-year PPA from adjacent 2.5GW Susquehanna nuclear plant; 2025 expanded agreement for up to 1,920MW by 2032. AWS acquired Talen's Cumulus campus for $650M (acquisition price; full campus buildout cost separate).
