Two New Commissioners Headed to the Arizona Corporation Commission

The Arizona Corporation Commission will transition to a bipartisan composition beginning in January when two newly elected Democratic commissioners, Clara Pratte and Jonathon Hill, assume their positions. They will serve alongside incumbent Republican commissioners Lea Márquez Peterson, Rachel Walden, and René Lopez.

The timing of this transition coincides with several significant policy matters under ACC consideration. The commission is reviewing proposed rate increases for major utilities Arizona Public Service Company and Tucson Electric Power Company, as well as examining potential mechanisms that would permit these utilities to implement rate adjustments annually with reduced opportunities for public participation. Additionally, the ACC is beginning its review of the utilities’ long-term resource planning proposals.

Energy policy observers have emphasized the substantial influence the ACC exercises over Arizona’s energy future. According to analysis from environmental organizations, the commission’s decisions have far-reaching implications for public health, electricity costs for consumers, and the state’s energy mix. Arizona currently faces a significant expansion in fossil gas infrastructure development driven by data center power demands. Residents in the state pay among the nation’s highest electricity rates while facing some of the most extensive natural gas infrastructure buildout planned nationally. Arizona’s largest utility continues operating the Four Corners coal facility with plans to maintain operations for more than a decade longer.

Environmental advocates have voiced concerns about the ACC’s historical decision-making patterns, noting a tendency toward rate increases and preference for fossil fuel investments over renewable energy expansion and efficiency measures. The newly elected commissioners’ entry into the body has prompted calls for reexamination of these policies, with stakeholders emphasizing voter demand for prioritizing clean energy solutions and cost containment for ratepayers.
