Development

In developmentAnnounced or preconstruction

QTS Phoenix 3 is an in-development campus in the Glendale/Litchfield Park area of Arizona. QTS publicly lists multiple building addresses, water-free cooling and construction/job commitments, while its older technical sheet described 280+ MW of planned campus capacity; the earlier 750 MW figure remains an external expansion estimate.

Development, permitting and phased deliveryAnnounced or preconstruction

No project-specific MW basis was verified in the reviewed public sources. The available public sources do not establish a single project-scoped capacity figure.
