On-site APS substation serves existing campus; power extended to new buildings
Microsoft's Arizona datacenters use adiabatic cooling - zero water for cooling more than half the year (outside air below 85F), switching to evaporative ('swamp-cooler'-style) above 85F; Microsoft and Gila River Water Storage replenish Phoenix-AMA groundwater with long-term storage credits dedicated to El Mirage and Goodyear. No El Mirage-specific water-use (MGD) figure is published.
Community sentiment
El Mirage Planning & Zoning recommended the PHX-83 expansion 4-0 and the City Council approved the site-plan amendment (2024); Microsoft's Datacenter Community Pledge commits to not raising residents' electricity prices, replenishing more water than it uses, local jobs, and tax base. Luke AFB flagged a bird-strike mitigation note on cooling ponds. No organized opposition found.
