Colorado's largest data centre, QTS Aurora, seeks permission to add 98 diesel backup generators to its campus south of Denver, bringing the total fleet to 138 units to support a 160-megawatt hyperscale facility. The expansion has triggered air quality concerns in Aurora, which is already in severe ozone nonattainment, with regulators reviewing the permit and a 30-day public comment period expected.

◆ ◆ The Wire takeaway
Data centre operators in ozone nonattainment zones now face tightening generator emissions rules that will drive hardware and siting decisions. If you supply cooling, power resilience, or emissions-control kit to hyperscale facilities, your customers' permitting cost and timeline just got longer—and those without clean backup power plans will lose site bids.
