Data centers are a hot topic for Arizona state officials in April, as the Arizona Corporation Commission has scheduled a workshop on the subject and the governor’s office has released a task force report with six data center-related recommendations.
The Arizona Corporation Commission workshop April 16 comes about a year after Commissioner Kevin Thompson opened a docket to review data center rate classifications and the possibility of more transparent rates.
Thompson said the docket could explore other topics such as behind-the-meter solutions for data centers and user-funded generation to help large customers meet their power needs.
“It’s important to balance the economic opportunities presented by data centers with the need to financially protect other ratepayers to ensure they are not bearing the rising energy generation and transmission costs associated with this burgeoning industry,” he said.
An agenda for the April 16 workshop was not yet available.
Revisiting Tax Incentives?
Gov. Katie Hobbs on April 2 released a report from the Arizona Energy Promise Taskforce, a group she established through a September 2025 executive order.
The 36-member task force consisted of private and public sector representatives, consumer advocates and subject-matter experts, whose goal was to address Arizona’s rapid growth in electricity demand. The work was managed by the Governor’s Office of Resiliency.
The task force report is divided into three sections, with one section devoted to data centers and other large loads.
The task force recommended an update to tax and financial incentives for large load customers. One possible next step is to propose statutory changes for the legislature to consider, “including eliminating the current tax incentive for data centers.”
Although task force members reached consensus on the recommendations, the Data Center Coalition, Microsoft and Google dissented on the recommendation regarding tax incentives.
Another recommendation is to require or incentivize large load customers to “proactively engage with communities and invest in community-identified priorities.” The report noted that siting and permitting large load facilities is becoming more difficult “due to local opposition and land-use conflicts.”
The task force also recommended helping local governments navigate large load development. That might include creating a technical assistance program for local jurisdictions and providing materials that explain to the public the energy, water and affordability considerations of large load facilities.
Other data center recommendations include:
-
- supporting large load customer adoption of energy management tools;
- exploring bring-your-own-capacity initiatives that work with utilities for project delivery; and
- supporting the ACC’s data center docket “to prevent cost shifts, mitigate stranded asset risks and increase development transparency.”
In addition to the task force report’s large load discussion, the report includes sections on an Arizona strategic energy plan and a generation and transmission corridor strategic plan. The task force issued 31 recommendations.
“[The task force] came together and developed commonsense policies that lower costs, reduce bottlenecks and can help us deliver continued prosperity and economic growth,” Hobbs said in a statement.
Stakeholders Weigh In
Since Thompson opened the data center docket at the Arizona Corporation Commission in April 2025, comments have poured in from utilities, advocacy groups and Arizona residents.
In a July filing, Arizona Public Service said it had committed to serving about 3,296 MW of data center load, including 1,215 MW from existing facilities, with prospective customers expressing interest in about 17,000 MW.
“Through commission regulatory policy, customer contractual protections, and reforming rates for high-load-factor customers, Arizona can ensure that costs are fairly allocated … and large, high-load-factor customers do not shift cost to other customers,” APS wrote.
Southwest Gas also said it is seeing growth in its service territory, including inquiries from data centers and others with a high demand for natural gas. The company said it supports the commission’s efforts to address data center growth.
Resident Margo Itule wrote to the commission to highlight what she called “the dramatic dangers of data centers,” which she referred to as “energy vampires.”
“These mega corporations are harvesting and depleting our precious resources,” Itule said.
