Who is behind it
The record, newest first
Prime announced groundbreaking on buildings 1-3 (48 MW each), said phase 1 of a roughly 250 MW on-site substation is commissioned, and raised the investment to $3 billion. (Business Wire (Prime Data Centers release), May 21, 2026; CommercialSearch, May 22, 2026)
Prime announced a 210 MW, 66-acre, five-building Avondale campus, with the first building targeted for Q3 2025. (Data Center Frontier, May 4, 2023)
AZBEX reported a revived PAD rezoning and general plan request for about 1.3M sq ft of data centers in five buildings at the Hermosa Ranch Technology Park site in Avondale, after an earlier request was withdrawn; the story does not name the developer. (AZBEX, Aug. 9, 2022)
Conflicts and open questions
- The 2022 AZBEX story does not name Prime in its text (only in its tags); the link to Prime is inferred from matching scope (1.3M sq ft, five buildings) and city. Treat the place and the 2022 event as inferred.
- Utility not named in sources; power via a dedicated on-site substation of about 250 MW.
- Evidence is reported: the 2026 announcement is a company press release; no Avondale approval document for the Prime parcel was opened.
- The 2023 'more than $2 billion' figure is from Avondale's mayor quoted by Data Center Frontier.
