Arizona’s public utilities governing body is exploring its options for legal action against Attorney General Kris Mayes.
The Arizona Corporation Commission (ACC) accused Mayes of illegally impeding its ratemaking authority for political gain. Mayes is running for reelection. Although she has no primary candidates, she will either have to face off against one of two Republicans: Arizona Senate President Warren Petersen (R-LD14) or Air Force reservist prosecutor Rodney Glassman.
As part of a commission press release sent out on Monday, ACC Chairman Nick Myers issued a statement saying the ACC had to “force” Mayes to fulfill her attorney general duties toward the commission.
“She was unlawfully pocket vetoing our commission ratemaking authority by delaying the process pertaining to the repeal of the natural gas subsidies,” said Myers.
Myers also accused Mayes of “play[ing] politics,” naming Mayes’ disapproval of the ACC’s appeal of the Renewable Energy Standard and Tariff (REST) rules. The ACC submitted that appeal and one other for the Gas Utility Energy Efficiency Standard (Gas EE) rules to Mayes’ office for review.
“These costly mandates forced Arizona ratepayers to pay almost $4 billion more than they should have over the last 20 years,” said Myers. “The commission will continue to protect the ratepayers and will not allow the Attorney General to arbitrarily increase rates against the decision of the commission.”
In 2006, the ACC gave utility companies a new mandate through the establishment of the REST rules: generate 15 percent of their energy from renewable resources by 2025, and submit annual implementation plans describing compliance. Mayes was on the commission at the time.
The ACC unanimously voted to repeal the REST rules in March, citing in part a $2.3 billion financial burden for compliance passed on to customers through surcharges.
The ACC said in its most recent press release that Mayes had gone beyond her statutory authority — which they described as ministerial — since she had conducted a substantive review of ACC’s ratemaking rules authority. ACC contends their ratemaking rules authority is constitutionally exclusive and leaves no room for interpretation by the attorney general.
In her denial of the ACC appeal, Mayes claimed in a letter to the commission that it had violated its own rulemaking procedures. The commission denied this assessment and accused Mayes of vetoing rulemaking based on policy disagreement.
Mayes approved those impacted rules which mandated renewable energies while she was on the ACC.
The ACC called these “unnecessary subsidies,” and claimed Mayes’ denial of the rule appeal was a cover for her alleged ulterior motive: preventing the ACC from undoing her work to push renewables.
“As a commissioner, Kris Mayes voted for these expensive subsidies that have cost ratepayers billions of dollars,” said Commissioner Kevin Thompson. “It is an abuse of her position as Attorney General to use the ministerial rule approval process to substantively veto our lawfully enacted ratemaking rule repeal. Every day that goes by, she is responsible for increasing costs on ratepayers.”
This is the latest development in an ongoing power struggle between Mayes and the ACC.
Back in 2024, Mayes sued the ACC over its decision to reverse a Power Plant and Transmission Line Siting Committee order regarding environmental oversight for a UniSource Energy power plant project. A superior court judge ruled against the ACC last October.
And in April, Mayes hit the ACC with three rehearing requests for three different alleged issues.
Mayes spokesman Richie Taylor told the Arizona Capitol Times that Mayes had to take on ACC responsibilities because the ACC was giving “sweetheart deals” to data centers while raising utility rates on senior citizens.
“Chairman Myers should focus on fulfilling the constitutional obligations of the Commission on behalf of Arizonans so the Attorney General doesn’t have to step in and do it for them,” said Taylor.

The Arizona Corporation Commission (ACC) is urging residents to contact their electric utility providers now as summer temperatures rise and higher electricity bills are expected to impact households across the state.
According to a press release, the ACC warned that triple-digit temperatures and increased air conditioning use typically drive significant month-to-month increases in electricity bills beginning in June and continuing through the summer months.
The commission said higher summer energy usage can create affordability challenges for households and businesses and encouraged customers concerned about paying utility bills to reach out to their electric providers before balances become unmanageable. Utilities may offer payment arrangements, budget billing programs, and financial assistance options to eligible customers.
“As we head into summer, I encourage ratepayers to explore ways to manage their energy use and to contact their electric utility if they need financial assistance,” Arizona Corporation Commission Chairman Nick Myers said. “The Commission’s responsibility is to ensure rates are just and reasonable, while ratepayers have the ability to control their monthly bills through their energy usage.”
Commissioner Lea Márquez Peterson urged customers to prepare early for summer utility costs and highlighted the commission’s seasonal protections against service disconnections.
“It’s important that our regulated utility customers prepare now for the heat of Arizona’s summer months by reaching out to their utility to learn about energy saving tips and programs that can help during financial hardships,” Márquez Peterson said. “Remember – the ACC has approved a disconnection moratorium from June 1 – October 15 to ensure customers are not disconnected for non-payment and can work out a payment plan.”
The ACC said weather remains the largest driver of summer electricity costs and advised consumers not to delay seeking assistance if they anticipate difficulty paying upcoming bills. The commission said early communication with utility providers can help customers access support programs and avoid financial hardship.
The commission also provided several energy-saving recommendations for Arizona residents during the summer months, including keeping blinds and curtains closed, using fans for personal cooling, limiting use of high-energy appliances during peak hours, regularly replacing HVAC filters, and investing in smart thermostats or energy-efficient appliances when possible.
According to the ACC, several utility providers and assistance organizations offer relief programs for qualifying customers. Those include Arizona Public Service’s Energy Support Program (ESP) and Crisis Bill Assistance (CBA) resources, Salt River Project assistance programs, Tucson Electric Power’s Power AZ program, UniSource Energy Services payment assistance, and programs administered through Wildfire and community action agencies.
APS is currently seeking a residential rate increase from the ACC of approximately 14.5%. Residents packed a recent hearing to oppose the proposal, while Administrative Law Judge Charles Hains began reviewing testimony and evidence that will inform a recommended rate decision for commissioners to consider.
In a statement to the outlet, APS defended the increase, stating that “… over the past five years, APS has experienced rapidly rising costs of equipment needed to deliver power to customers. One example is transformer costs which are, on average, 49–90% higher now than when our rates were last set.”

State Rep. Ralph Heap (R-LD10) would like to take the Arizona Corporation Commission (ACC) off the path of green energy and onto a different path in line with President Trump’s energy agenda.
The state’s largest regulated utilities, APS and TEP, are pursuing 14 percent rate hikes with the ACC after receiving other double-digit rate hikes the past few years. Heap, an “Arizona First” candidate, argues that the ACC should be prioritizing ratepayers, and that his approach to the ACC would end the constant upward trend of rates.
Heap’s platform prioritizes individual ratepayers over trendy policy and cash-flush companies: implementing greater protections for rural Arizonans’ energy and water access, rejecting “radical” agendas like the Green New Deal and “corporate welfare” programs, encouraging a free-market energy system, and creating more resistance to rate hikes.
The lawmaker laid claim to the engrossment, passage, or sponsorship of multiple energy-related bills from 2024 to present. Those bills were:
- HB4097: authorizing “bring your own power,” or self-supply, for large customers to expand energy supply options without creating an open retail-choice program;
- HB2679: establishing a defined legal path for financing utility transition costs;
- HCR2022: committing support for nuclear generation through the Palo Verde Generating Station;
- HB2042: creating enforcement on geoengineering activity by prohibiting intentional in-state release of materials for solar radiation management, prohibiting public funding for those technologies, and authorizing attorney general investigations;
- HB2328: limiting rate disparity in intermunicipal water service by requiring municipal providers selling water to another municipality’s public to charge rates constrained by specified comparators;
- HB2331: ensuring reliability within long-range resource planning by requiring covered public power entities and electric utilities to ensure at least 85 percent of relied-on generating capacity comes from reliable resources by 2030;
- HB2915: granting county-administered property tax reductions to homeowners suffering depleted property values due to nearby renewable energy facilities; and,
- HB2918: ending property tax breaks for new utility-scale renewable energy projects.
Since taking office last January, Heap has maintained several leadership positions, including vice chairmanship of the Natural Resources, Energy, and Water Committee.
Prior to his legislative service and ACC run, Heap practiced orthopedic medicine in the East Valley for nearly 40 years. During that time, he participated in medical missions to developing countries where the presence or absence of reliable energy meant life or death. Heap attributes his “ratepayer first” attitude and interest in reliable, affordable energy to those experiences.
Heap married his high school sweetheart, Denise. Together they have three children—including Maricopa County Recorder Justin Heap—and eight grandchildren.
As part of his “ratepayer first” approach, Heap qualified as a Clean Elections candidate. He has sworn against taking money from regulated utilities or their PACs.
Heap has received many endorsements from grassroots leaders along with state and municipal elected officials, including former ACC Commissioner and current state representative Justin Olson (R-LD10), Rep. Eli Crane (R-AZ-02), and a leading Republican lawmaker who resigned earlier this year to run for Congress, Joseph Chaplik.
Many of the heavyweights in the Arizona legislature put in their support for Heap: Arizona Freedom Caucus leader and State Sen. Jake Hoffman (R-LD15) as well as State Reps. Michele Pena (R-LD23), Laurin Hendrix (R-LD14), Khyl Powell (R-LD14), Lisa Fink (R-LD27), Rachel Keshel (R-LD17), Alexander Kolodin (R-LD03), Beverly Pingerelli (R-LD), Michael Way (R-LD15), John Gillette (R-LD30), Teresa Martinez (R-LD16), Leo Biasiucci (R-LD30), Pamela Carter (R-LD04), and Chris Lopez (R-LD16).
Among those municipal endorsements were supervisors from Gila and Navajo counties; the mayors of Payson, Snowflake, and Springerville; and council members for Payson.

The Arizona Corporation Commission approved a temporary bill credit for UNS Electric customers, expected to reduce monthly costs during peak summer usage.
According to a Wednesday press release, the Commission approved an $18.50 monthly credit for customers with average usage of 884 kilowatt-hours. The credit will be in effect from May 1, 2026, through December 31, 2026. The measure was approved in a 5–0 vote during the Commission’s open meeting on April 8.
The adjustment is tied to the Purchased Power and Fuel Adjustment Clause (PPFAC), a mechanism which utilities use to recover fuel and purchased power costs. The Commission stated that utilities do not earn a profit on expenses recovered through the PPFAC.
Commissioner Kevin Thompson said in the release that the credit follows the Commission’s earlier action to address a significant under-collection in the PPFAC balance.
In May 2023, the Commission approved a temporary surcharge to reduce the balance, which was accruing interest costs that were being passed on to ratepayers.
“The Commission had to make a tough vote in 2023 to pay down significant fuel cost debt that had been allowed to build as a result of circumstances outside the utilities’ control,” Thompson said. “As a result of the temporary surcharge, UNS was able to rapidly pay down the debt and save ratepayers money in the long run. Asking ratepayers to pay more in their monthly bills to pay down costs is never an easy task, but this solution removes the massive debt hanging over the heads of the ratepayers and provides additional bill relief when customers need it most.”
The surcharge was eliminated in December 2025 after the balance was paid down. The Commission said that the change reduced the average residential customer’s bill by approximately $20 per month.
Following the removal of the surcharge, the utility reported a positive PPFAC balance of $5.6 million in mid-February 2026, which has continued to grow.
According to the release, UNS Electric began experiencing under-collection in October 2021, which grew to approximately $48 million. The deficit was attributed to increased natural gas prices during the COVID-19 pandemic, extreme weather events including Winter Storm Uri, and global energy market impacts related to the Russian invasion of Ukraine.
“As we are approaching the summer heat, I am glad the Commission was able to provide some rate relief for customers in Kingman, Lake Havasu, Nogales, and other smaller communities in Mohave and Santa Cruz counties,” Chairman Nick Myers said in a statement.
With the new temporary credit in place, the Commission said a typical residential customer is expected to see an average monthly reduction of approximately $38 this summer compared to the same period last year.
“As regulators we often have to make difficult decisions as we balance the various interests involved in ratemaking,” Myers said. “In this case, I am pleased that our difficult decision to address the PPFAC in 2023 has resolved the problem and resulted in a meaningful reduction in rates for UNSE customers through the end of the year.”

The Arizona Corporation Commission (ACC) will host its annual 2026 Summer Preparedness Workshop on Tuesday, April 14, at 9:00 a.m. in Hearing Room One at the Commission’s Offices. The workshop will also be available virtually.
This annual event serves as a critical exercise in which Arizona’s regulated electric utilities present detailed plans to the Commission outlining their readiness to meet peak electricity demand during the state’s intense summer heat.
The workshop allows the ACC to review utility preparations, verify proactive grid maintenance efforts year-round, and confirm that infrastructure remains safe, reliable, and resilient for customers.
Arizona’s summer temperatures routinely drive record-breaking electricity demand as residents rely heavily on air-conditioning. In recent years, major utilities—including Arizona Public Service (APS), Salt River Project (SRP), and Tucson Electric Power (TEP)—have repeatedly set new peak demand records amid scorching heat, with highs often exceeding 115 degrees in the Phoenix area.
In 2025, utilities forecasted and prepared for peaks exceeding 8,400 MW for APS and SRP each, while emphasizing additions of solar, battery storage, and other resources alongside adequate reserves to maintain reliability.
The commission uses the workshop to ensure utilities demonstrate sufficient generating capacity, transmission readiness, maintenance schedules, emergency response protocols, and contingency measures for high-demand periods.
