Microsoft PHX-10 Goodyear Campus

Microsoft. Operating. 143 MW.

Microsoft's PHX-10 campus anchors the Azure West US 3 region in Goodyear and is fully operational, with Phase I and II delivering a combined 143 megawatts of IT load as of 2026. Microsoft has committed 36 million dollars toward a 90 million dollar expansion of Goodyear's 157th Avenue wastewater treatment plant to support reclaimed water for cooling, and newer buildings in the region are shifting to air-cooled designs that Microsoft says avoid an estimated 42 million gallons of fresh water per building each year.

What it would mean nearby

Reported as evaporative cooled. At 143 MW it would draw roughly 453,000 to 1.6 million gallons of water a day, about what 5,200 households use.

Arizona Public Service is asking the commission for a 16.4% residential increase (2025 general rate case (docket E-01345A-25-0105)). On a $160 monthly bill that is about $22 to $30 a month.
