Developers and practitioners evaluating data center projects in Arizona face a regulatory environment shifting on three fronts simultaneously. Federal executive orders are opening new land, streamlining permitting, and channeling financial incentives toward qualifying projects — but they are not preempting the state and local rules that most directly affect project economics. A carve-out in the December 2025 Artificial Intelligence (AI) Framework Executive Order preserves Arizona’s authority over data center infrastructure, meaning the Arizona Corporation Commission’s (ACC) rate-classification docket, municipal zoning restrictions, water-use ordinances, and pending grid cost-allocation legislation remain the binding constraints on project feasibility. Understanding where federal tailwinds end and state and local headwinds begin is essential for any developer sizing risk or selecting sites in the state.
