Updates, newest first

  1. Oct. 21, 2026 As of Oct. 21, 2026, QTS's campus page lists the Aurora-Denver 1 site at 1160 N. Gun Club Road with 65 acres and more than 160 MW of planned critical capacity. (QTS Data Centers, undated)
  2. Aug. 11, 2026 Colorado Politics called the QTS campus the largest data center project under construction in Colorado, needing about 160 MW when complete. (Colorado Politics / The Denver Gazette, Aug. 11, 2026)
  3. July 8, 2026 CPR reported the generator application was still under review, with a 30-day comment period expected after public notice, and that state compliance staff were checking whether construction so far met air rules; QTS said it was fully authorized to proceed. (Colorado Public Radio, July 8, 2026)
  4. Oct. 26, 2025 Big Pivots described QTS as Colorado's most prominent data center, with a 10-year ramp-up on its Aurora campus. (Big Pivots (via KUNC), Oct. 26, 2025)
  5. July 2025 QTS applied to state air regulators to modify its permit and add 98 diesel backup generators to the 40 already installed, and to raise yearly testing from 24 to 36 hours. (Colorado Public Radio, July 8, 2026)
  6. Feb. 2025 CPR reported QTS received local construction permits for the campus expansion in February 2025. (Colorado Public Radio, July 8, 2026)

Conflicts and open questions

  • Campus size differs by source: 65 acres (QTS; CPR, 2026) and 67 acres (Big Pivots, 2025); power is at least 160 MW (QTS; CPR; Colorado Politics) or 177 MW (Big Pivots).
  • County: the Census geocoder places QTS's listed address in the Arapahoe County part of Aurora.
