Arizona Corporation Commission hearing to focus on data centers

The Arizona Corporation Commission is convening a special workshop on April 16 to address the significant impact of data centers and other "large-load facilities" on electric bills and grid reliability across the state. This initiative follows a recent warning from a governor’s task force, which emphasized the need for comprehensive policies to manage economic growth without compromising grid stability or unduly increasing costs for existing customers. The task force, comprising industry leaders and consumer advocates, highlighted supply chain limitations for critical equipment and advocated for greater transparency and fair cost allocation for these rapidly expanding facilities, which contribute to "upward pressure on rates." The workshop, chaired by Kevin Thompson, aims to review existing rate classifications and potentially establish more transparent rates for data center customers, along with exploring utility mechanisms and user-funded generation solutions. While no substantive votes will occur, the commission will hear from entities such as the Residential Utility Consumer Office, power producers like Salt River Project (SRP), and the Goldwater Institute (a free market advocacy group). Commissioner Thompson initiated this inquiry, noting the exponential growth in Arizona's power needs, and stressed the importance of balancing economic opportunities with protecting ratepayers from rising energy costs. A specific point of contention, the proposed 1-million-square-foot data center campus by Menlo Equities in east Ahwatukee, a residential area of Phoenix, will not be a focus of the workshop despite local outcry. Residents have expressed alarm, citing concerns about electric bills, health, and quality of life, and over 2,162 people have signed a change.org petition against the project. Although the site's zoning was changed by the Phoenix City Council in 1997 to include data centers, opposition remains active. Salt River Project (SRP), involved in providing a substation for the Menlo project, has submitted filings to the commission outlining challenges in meeting significant load growth and preventing cost shifts to other customers through dedicated substation service and pre-payment requirements for infrastructure upgrades. The state currently has approximately 1,300 MW of data center development under construction and over 4,000 MW in planning stages.
