Arizona Republicans concede utility board seats as 14% APS rate hike vote looms
Democrats Clara Pratte and Jonathon Hill are set to end Republicans' hold on all five seats of the board that sets Arizona's power rates. But the outgoing all-Republican board still has until Dec. 31 to rule on a requested increase of about 14% for the state's largest utility.

Arizona's Republican candidates for the state's utility regulator have conceded. That puts Democrats on track to win seats on a board that sets power, water and gas rates for millions of Arizonans 13. Incumbent Commissioner Kevin Thompson conceded on Thursday, a day after fellow Republican Ralph Heap, according to the Yellow Sheet Report 1.
The race has not been officially called. As of Thursday evening, Democrat Clara Pratte had 27.1% of the vote and Democrat Jonathon Hill had 26%. Thompson had 23.5% and Heap had 22% 1.
The Arizona Corporation Commission is a five-member elected board. It regulates and sets rates for the state's electric, water and gas utilities 3. Republicans hold all five seats 1. The board has had no Democrat since Commissioner Anna Tovar left at the end of 2024, The Arizona Republic reported 4.
A big rate decision before the new members arrive
The timing is the catch. Arizona Public Service, known as APS, is the state's largest utility, and it has asked for a rate increase of about 14% 5. The commission is likely to decide that case in December, after the election but before any new commissioner takes office, The Copper Courier reported 5.

The commission's own timeline backs that up. An administrative law judge is due to issue a recommended decision by late November 2026. Commissioners must vote on it by Dec. 31, 2026, and any new rates would likely take effect in early 2027 6. If their leads hold, Pratte and Hill would join the board in January 3.
When APS filed the request in June 2025, it asked for a net increase of 13.99%. That works out to about $20 more a month for a typical customer using 1,000 kilowatt-hours 7. Tucson Electric Power, known as TEP, is also near the end of its own case seeking about 14% 4.
Arizona Attorney General Kris Mayes, a Democrat, came out against the APS request when it was filed. She said customers were already paying $12 more a month for electricity than a year before 7. APS President and CEO Ted Geisler defended the request, saying, "Reliability isn't optional —it's essential, especially in Arizona." 7
What the Republican commission did
Thompson is a former gas industry lobbyist. He helped the commission repeal rules that Republicans said were costing consumers too much, including renewable energy requirements 1. The commission also repealed the state's energy efficiency standards in July 5.
Bills have kept rising. In 2024 the commission approved an APS increase of about $10.50 a month. Regulators also extended an APS fuel charge instead of letting it end. Altogether, the average APS bill rose nearly 20% from 2020 to 2024 5.
In a September debate, Thompson said "We'll cut the fat" and promised the commission would hold utilities accountable. He also noted that Arizona law lets utilities recover their costs from customers 8. In his concession, he defended his time on the board 1.
Heap largely stopped campaigning while he faced a Clean Elections Commission complaint about campaign finance rules 1. Former Commissioner Nick Myers, a Republican who lost to Heap in the primary, called the result "beyond embarrassing" 3.
What the Democrats say they will do
Pratte co-founded Navajo Power, which partners with tribal communities on renewable energy projects. Hill is a spacecraft engineer and geologist at Arizona State University 1. Both say the current commission defers too much to utilities. They favor an energy mix led by renewables, which they argue are the cheapest and fastest to bring online 1. Pratte, a member of the Navajo Nation, would be the first Indigenous woman elected to statewide office in Arizona 3.
Pratte has framed the job around household budgets. "I grew up without running water and electricity, so I know firsthand how hard that is to make those decisions between having access to something and paying for your groceries or your prescription medications," she told KOLD in September 9.
Two new members can't outvote three Republicans. Hill has said they would still have tools: "We might not be able to initially change a vote, but we can subpoena all sorts of documents." 5 He has also asked voters to keep paying attention.
Why this matters for older Arizonans
In Arizona, power bills can be a matter of safety. In 2024, an 82-year-old woman died after her power was shut off in mid-May, when temperatures hit 99 degrees. APS did not admit wrongdoing but settled a lawsuit with the state for $7 million 5. APS now pauses shutoffs on days that reach 95 degrees or higher. Pratte has pointed out that the rule "does not stop the bill" 5.
On the same ballot, early results showed Tucson voters rejecting a 25-year franchise deal with Tucson Electric Power. Inside Climate News tied that vote to TEP's request for a big rate increase 10.
That matters because the change on the commission is coming late. The outgoing Republican majority still controls the December vote on APS rates. Customers will start to see what the new members can do only after that decision is made 56.
