Arizona voters will decide two open seats on the five-member Arizona Corporation Commission during the November 2026 midterm election. This vote carries direct implications for local operating costs, as utility rates are projected to rise between 14% and 16% this December.
Why it matters
The outcome of this election will determine the regulatory oversight of future utility rate case hearings, which have been driven by rapid population growth. For operators, the election represents a pivot point regarding the regulatory stance on managing these rising costs versus consumer affordability.
Utility rates are set for a potential 14% to 16% increase in December 2026, following a period of sustained rate hikes over the past 4.5 years. Voters will decide two of the five seats on the commission that oversees these adjustments.
The players
Arizona Corporation Commission
A five-member statewide regulatory body that governs utility rate hearings and energy policy.
Clara Pratte
A candidate for the Arizona Corporation Commission and member of the Navajo Nation campaigning on affordability.
The details
The Arizona Corporation Commission maintains authority over utility rate case hearings and regional feedback sessions. Commissioners serve as the ultimate arbiters between utility companies seeking revenue to support infrastructure for rapid population growth and the mandate to keep costs affordable for commercial and residential users. Candidates like Clara Pratte are framing their platforms around this specific tension of affordability.
Timeline

Market Landscape
This election follows a well-established pattern where the Arizona Corporation Commission serves as the primary regulatory lever for energy infrastructure costs. The result marks a potential continuation of the regulatory trends seen in previous utility rate case hearings.
Businesses should anticipate a potential 14% to 16% rise in overhead starting this December. Owners should review energy efficiency strategies and prepare their budgets for these likely utility cost adjustments following the November election.
The takeaway
The November commission election will directly shape how the state balances infrastructure demands with the affordability of utility services. Operators should monitor the election results to better forecast their own variable cost adjustments for the start of 2027.
