Updated: Oct 28, 2026

QTS Phoenix DC1 40th Street Data Center Campus, also known as QTS Phoenix 1, is a data center project in Phoenix, AZ, US developed and operated by QTS Data Centers. 85-acre multi-building campus; 280+ MW current planned campus capacity; DC1 provides 42 MW of critical power. Owned expandable onsite substation, four diverse underground fiber laterals, redundant conduit paths and closed-loop dry cooling. The 280+ MW figure is the planned full-campus envelope at 1200 N 40th Street. The legacy PHX1 alias conflicts with QTS’s downtown Van Buren PHX1 naming, so the project identity and capacity basis remain unresolved. The cited identity or capacity sources conflict and do not establish a single project-scoped capacity figure.
