The Arizona Corporation Commission (ACC) regulates all investor-owned oil, gas, electric and water utilities.
The five commissioners vote on proposed rate increases and major infrastructure investments
like power plants and substations.
The Commission was created by the Arizona Constitution. The ACC is often referred to as Arizona's fourth branch of government because commissioners can sign executive orders, pass laws and act as judges.
Their stated mission is to ensure safe, reliable and affordable utility services, ensure the safety of railroad and pipeline systems, grow Arizona’s economy by helping local entrepreneurs start businesses, and protect citizens by enforcing an ethical securities marketplace.
There are multiple ways you can engage with the Commission as they are considering different proposals during rate cases, hearings, or open meetings. Open meetings are where all major decisions are made.
This year, the stakes are especially high.
The ACC will decide two major utility rate cases that could significantly impact household budgets. Both APS and TEP are seeking a 14% bill increase. That’s an average of $16 - $20 more each month. If approved, the new rates will hit customer bills in mid-2026. We must show up, speak out, and demand regulators put Arizona families over corporate profits!
The public hearings have passed, but you can still make your voice heard by submitting a comment online.
The most effective way to make your voice heard is to attend an open meeting and speak directly to the commissioners. There are rules for public comment but anyone can do it and it makes a difference. Just make sure to have your thoughts organized and always be respectful!
You can also send a message to the commissioners that will be part of the public record. First, search for the case you want to comment on in the docket. Next, enter the docket number into that section of the online comment form. Then write your opinion and submit!

In 2006, AZ was one of the first states to pass a Renewable Energy Standard, requiring utilities to have at least 15% of their generation portfolios come from renewable sources by 2025. Since then, the Commission has consistently attacked and undermined clean energy.
This November we can elect two new commissioners who will fight for ratepayers and establish Arizona as a national leader in clean energy!
