Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

   Underlying source

   Microsoft's own Greater Phoenix community page describes El Mirage as an operating datacenter ("Microsoft operates datacenters in El Mirage and Goodyear"); the source does not disclose an in-service date, so this event is dated to confirmation.

   Underlying source

Source notes

The investment figure is land-purchase cost only; total campus investment is higher. PHX-83 is the fifth building on existing El Mirage campus. Coordinates are El Mirage city centroid; site is at SE corner of Dysart Rd and Olive Ave. Arizona's Sec. 41-1519 sales/use-tax exemption applies by statute but no campus-specific certified award was found; published job figures cover the combined West Valley (El Mirage/Goodyear) campus, not El Mirage alone.

On-site APS substation serves existing campus; power extended to new buildings
