The record, newest first

  1. New Project Media reported that residents west of the site had appealed the CUP and that a hearing officer would set the schedule. (New Project Media, July 7, 2026)

  2. The Iron County Planning Commission unanimously approved the CUP with 62 conditions for up to five buildings, phased over 8 to 10 years. (St. George News / Cedar City News, June 5, 2026; The Salt Lake Tribune (republished by Iron County Today), June 8, 2026; Pronghorn Development LLC (news release via Utah Policy), June 10, 2026)

  3. KUTV previewed the planning commission vote; proposed conditions included a dedicated gas plant and noise mitigation, and the project projected 670 direct jobs. (KUTV, June 3, 2026)

  4. The Tribune reported the Antelope application was complete, so the county's new data center moratorium would not pause it. (The Salt Lake Tribune, May 26, 2026)

Conflicts and open questions

  • Coordinates are from the internal lead pointer, consistent with the reported location on Antelope Springs Road roughly 15 miles northwest of Cedar City in Iron County; not parcel-verified.
  • Iron County's data center page links a CUP document set that was not opened. The appeal outcome is unconfirmed; St. George News (Aug. 30) did not report its status and no later report was found.
  • Evidence is marked reported because no county minutes or permit were opened; the county's project page lists the June 4 review only.
  • KUTV's June 3 preview gave the meeting date as June 5, but other reports and the county page give June 4.

The full record

Status note
Planning commission unanimously approved a CUP with 62 conditions; New Project Media reported in July 2026 that neighbors appealed.
Power note
On-site gas plant of up to 1.5 GW. New Project Media quoted the county planner as saying each phase pairs one data center building with a power block of about 300 MW using 18 generators, implying 90 Wartsila 18V50SF engines. The figure is generating capacity, not data center load, so no MW is counted for this campus.
