SpaceX says it is behind a 6 GW Cochise County campus plan

On Nov. 4, 2026 SpaceX told a Cochise County meeting that it stands behind a Tombstone Resources LLC application, filed Oct. 30, for a campus near the Apache Generating Station. The application describes about 747 acres, up to nine computing buildings, about 6 GW of grid demand at full build-out, about 1,500 MW in phase one, and on the order of $3.6 billion for transmission and substation work, with initial construction power targeted for April 2027. KVOA reported that Riley Trettle said the LLC name is used because the SpaceX name draws attention and that construction would begin immediately if the Dec. 9 hearing grants the permit.
