Phoenix sets new rules for data centers — including where they can go and how noisy they can be

The number of data centers in metro Phoenix has exploded in recent years, and the demand continues to grow with the boom of artificial intelligence.

The city of Phoenix has adopted new zoning rules for these developments.

Data centers often get public scrutiny due to their size, the noise they generate and the sheer amount of energy they use.

"Data centers are taking up land that I believe would be better suited to provide more housing, more health care access, access to healthy food, or more permanent job employers," said Phoenix Councilmember Anna Hernandez.

As cited in a Phoenix City Council report, the utility APS has 10 gigawatts in pending data-center requests. Last year’s peak load for all of its customers was about 8 gigawatts.

On Wednesday, council members unanimously approved requirements for how data centers can be designed, where they can go and set noise limits.

“We are still open for business and we want folks to come here, but we also need to marry that with the safety and health concerns of our community members, our visitors and our other businesses," Vice Mayor Ann O’Brien said.

An online tracking service shows there are about 130 data centers in metro Phoenix.
