PHOENIX - Arizona Public Service (APS) is donating $350,000 to support communities across Arizona recovering from severe storms that brought heavy rainfall and widespread flooding. Storms damaged homes, roads and other infrastructure, forced evacuations, and disrupted residents and businesses.

The donation will be allocated to several organizations that are actively supporting residents, local recovery efforts and small businesses in communities throughout the state, including the Verde Valley, northern Arizona and San Carlos Apache Reservation. 

"Restoring power safely and quickly is always our priority when severe weather hits, but our commitment to the communities we serve goes beyond the electric system,” said Mackenzie Rodgers, APS Vice President of Transmission and Distribution. “Our customers and neighbors are dealing with the impacts of these floods long after the storm has passed, and we want to help provide the resources communities need as they recover.”  

Immediate Aid for Verde Valley
Camp Verde and surrounding Verde Valley communities experienced significant impacts from the flooding, including evacuations, more than 300 contaminated wells and the destruction of two RV parks that housed year-round residents. APS will provide funding to support organizations working directly with those impacted, including:  

• Town of Camp Verde for community cleanup, infrastructure restoration and broader recovery efforts in one of the hardest-hit communities. 
• United Way of Yavapai County, which is providing direct assistance to residents impacted by flooding throughout the Verde Valley through its relief fund. 
• Sedona Chamber of Commerce Foundation, which is helping small businesses impacted by flooding recover-and-resume operations and supporting the area’s broader economic recovery. 

"The impacts of these storms have created significant challenges for our town, and recovery will require time, resources and support from our neighbors and beyond," said Marie Moore, former Mayor of Camp Verde and Supervisor-Elect of Yavapai County. "We're grateful to APS for being part of that effort to restore the Camp Verde community." 

Additional relief across Arizona 
APS will also provide funds to support flood relief efforts in northern Arizona and the San Carlos Apache Reservation, as both areas were also devastated by recent floods. Support includes:  

• San Carlos Apache Reservation, where flooding destroyed homes and damaged roads and other infrastructure. Rising waters forced evacuation and created needs for shelter, emergency assistance and longer-term housing recovery.  
• United Way of Northern Arizona, which is providing direct assistance to residents in both Coconino and Navajo counties who were impacted by the storms.  

This funding follows APS’s $250,000 donation announced last month to support Navajo and Hopi communities that were impacted by flooding in the Four Corners region, bringing APS’s recent flood-relief contributions to $600,000. 

Customer assistance resources 
APS customers experiencing hardship following the flooding can find support through several assistance programs: 

• APS Crisis Bill Assistance: Provides up to $1,000 per year in bill assistance for eligible customers experiencing a temporary financial hardship. 
• APS CARE: Provides up to $500 in crisis bill assistance through APS’s partnership with The Salvation Army, regardless of income.  

Customers can also learn more about available assistance at aps.com/assistance or speak with an APS advisor 24/7 by calling 602-371-7171 or 800-253-9405. 

TSMC Arizona is expanding its advanced semiconductor manufacturing operations in Arizona. To responsibly support that growth, on Nov. 6, 2026, APS filed with the Arizona Corporation Commission (ACC) a proposed 25-year Direct Pricing Contract (DPC) with TSMC Arizona.  The contract is designed to meet TSMC’s increasing energy needs, ensure that the costs of its growth are not shifted to other APS customers, and support APS’s commitment to reliable service for existing customers.

Who pays to develop additional energy resources?
The filing states that TSMC Arizona will make long-term financial commitments associated with new generation resources and service infrastructure, along with TSMC’s usage of shared system resources, which will protect other APS customers from costs associated with its growth.

The proposed agreement aligns with APS’s Pledge for Responsible Energy Growth, which guides how APS plans for and serves new energy demand.

How does the agreement protect reliable service?
The agreement will help APS serve TSMC Arizona’s long-term electricity demands, while ensuring high standards of reliability and preserving system capacity for existing homes, hospitals, schools, businesses, and communities. Some additional infrastructure being built will become part of the generation and transmission resources on APS’s grid, helping to maintain top-tier reliability for all APS customers. APS will continue to protect current customers while responsibly planning for Arizona’s future energy needs.

How is APS serving TSMC?
TSMC’s north Phoenix advanced semiconductor fabrication facility has been a fixture in APS’s service territory since 2020. The proposed agreement builds on this successful partnership and affirms APS and TSMC’s shared commitment to ensuring that other customers are protected as TSMC continues to grow in Arizona.

What happens next?
APS has filed the proposed Direct Pricing Contract, (a long-term agreement designed for customers with extra-large energy needs) with the ACC for its review and approval.

PHOENIX - Arizona Public Service (APS) has filed its 2026 Integrated Resource Plan (IRP) with the Arizona Corporation Commission, reflecting the Company’s focus on providing customers with reliable, affordable electricity as business and residential energy demand grows at record levels.

APS evaluated a range of possible scenarios and resource options to develop a strategy to meet demand while keeping customer costs low. The plan also reflects APS's long-standing approach that growth will pay for growth, holding large energy users, including data centers, responsible for the costs and risks associated with serving their energy needs.

The company files an IRP every three years, relying on extensive data modeling and analysis to evaluate how to meet customer demand during the next 15 years.

“Reliability is nonnegotiable,” said Mike Eugenis, APS Director of Resource Planning. “We developed this IRP by evaluating a wide range of scenarios over the next 15 years to ensure APS is prepared to serve customers who count on us for reliable and affordable service throughout Arizona.”

How fast is demand growing?

Growth in electricity demand was a central theme of APS’s previous IRP, and that growth has accelerated. APS forecasts that annual energy use will double by 2041 from 2026 levels and has seen continued expansion even while preparing the latest plan.

The IRP includes projections for demand growth based on weather, population, economic activity and energy consumption. The forecasts account for uncertainty about how these conditions may change.

APS projects a peak demand of more than 14,500 megawatts (MW) in 2041, with a 3.4% annual growth rate. Peak demand is the time when customer energy use is at its highest. The company’s current record peak was set on Aug. 2, 2026, when customers used 9,166 MW from 6-7pm.

Not only is the peak demand increasing, but the amount of energy used throughout the year is rising. Annual retail sales are forecast to double to about 80,600 gigawatt hours (GWh) in 2041, representing a 5% annual growth rate. Annual retail sales were about 34,200 GWh in 2025.

A balanced mix to meet near-term growth

In the next few years, APS will integrate thousands of megawatts of solar, wind and battery energy storage. By 2030, the company expects to have approximately 6,000 megawatts of battery storage on its system, helping balance renewable resources and providing energy during periods of high demand.

Alongside these historic levels of renewable energy and storage, the analysis found on-demand resources, including natural-gas generation, continue to play an important role in supporting a balanced energy mix and meeting customer demand. APS will add natural-gas resources through the new Desert Sun Power Plant, expansion of the Saguaro Power Plant and conversion of the retired Cholla Power Plant from a coal-burning resource. The IRP analysis found that these resources provide value across a wide range of future scenarios.

“A reliable electric system requires a diverse mix of resources that can serve customers under a wide range of conditions and all hours of the day, including periods when solar, wind and battery resources may not be available to meet customers’ needs,” said Eugenis.

The IRP also includes substantial expansion of the transmission system to connect new resources across Arizona. APS will continue evaluating emerging and future technologies, including the potential for new nuclear generation, geothermal energy and additional energy storage. Investments will depend on their ability to provide customer value, reliability and affordability.

The IRP is a guide, not a fixed blueprint. The near-term actions in the plan, particularly those in the next three years, reflect projects and decisions with greater certainty. Recommendations for resources in the years beyond reflect the best information available today about customer energy demand, technology, fuel prices, construction costs, resource availability and other conditions. APS continuously adapts its plans as conditions change. APS issues all-source requests for proposals to identify the best fit, most reliable and affordable resources available.

Four Corners Power Plant extension saves $1 billion

One conclusion in the 2026 plan is that continued operation of Four Corners Power Plant beyond 2031 could save customers close to $1 billion compared with replacing the plant with new resources.

As an existing, around-the-clock generator, Four Corners can continue supporting the grid while new generation, fuel and transmission infrastructure is developed. The plant is on the Navajo Nation in New Mexico and operates under a lease that requires retirement no later than 2038. The company will continue to evaluate the appropriate time to cease operations between 2031 and 2038, with the decision depending on customer needs, economics and other factors evaluated through future planning processes.

Growth pays for growth

APS is planning for increased electricity use from homes, businesses and large customers, including data centers. The company is ensuring large, energy-intensive commercial customers do not shift growth-related costs to residential or smaller business customers.

APS’s approach is consistent with the principles outlined in the APS Pledge for Responsible Growth: safeguarding reliability, protecting customer rates and preserving grid capacity. Large customers will cover the costs and financial risks associated with serving their energy needs. These protections support Arizona’s continued economic growth while helping preserve reliable service and keep costs low.

APS has prepared a detailed technical report, or “whitepaper,” assessing extra-large load customer generation costs and revenues from 2022 through 2025.

As detailed in the whitepaper, APS’s analysis found that residential customers did not subsidize extra-large load customer growth during the period examined – demonstrating that the third-party analysis cited in recent media reports reaches false conclusions by using methodology that is fundamentally flawed and misleading.

Key Takeaways

• APS’s cost and revenue analysis shows that extra-large load customers paid more than the estimated generation costs attributable to their growth. Their base fuel and PSA revenues exceeded the estimated incremental capacity and energy costs, helping to reduce the historic PSA balance for the benefit of all customers.
• The third-party analysis does not reflect the full cost picture. It fails to 1) distinguish between systemwide power purchases and resources acquired specifically for extra-large load growth; 2) incorrectly uses annual electricity consumption growth as a measure of new purchased-power needs; and 3) treats APS’s proposed future rate changes as evidence of historical subsidies. It also overlooks historic fuel and purchased-power under-collections, which reflect costs incurred in prior periods that extra-large load customers helped recover.
• The third-party analysis relies solely on retail sales growth. APS’s analysis details how extra-large load customers accounted for less than half (~42%) of measured peak-demand growth during the period, while the third-party analysis falsely attributes 96.5% of retail-sales growth to them. Residential customers produced the largest increase in peak demand (~546 MW) compared with extra-large load customers (~509 MW) and other general service customers (~152 MW).
• APS is taking steps to ensure future growth pays for growth. While extra-large load customers' revenues have exceeded the estimated incremental generation costs attributable to their growth, that margin has narrowed as capacity costs have increased. APS has proposed prospective measures in its pending 2025 rate case intended to ensure growth continues to pay for growth into the future. These include a substantial rate increase for extra-large energy users and annual cost-of-service updates to better allocate future growth-related costs. As of the date of the whitepaper’s publication, the Arizona Corporation Commission had not yet issued its final decision on these proposals.

The facts are clear: From 2022-2025, residential customers did not subsidize the generation costs associated with extra-large load growth. Instead, extra-large load customers paid fuel and purchased-power revenues exceeding the estimated incremental generation costs attributable to their growth.

When extra-large energy users expand in or come to Arizona, APS requires them to pay for the infrastructure and power needed to serve them, while protecting existing customers from any cost shifts and ensuring high levels of energy reliability and capacity for all customers and communities.

PHOENIX – Arizona Public Service (APS) is committing $250,000 to support communities impacted by historic flooding across the Four Corners region. The area, which includes northeastern Arizona, has endured torrential rains and flash floods over the past week. The harsh weather has damaged homes, disrupted roadways and triggered evacuations for many residents. Local emergency officials are preparing for additional evacuations as more storms are expected this coming weekend.

APS has longstanding ties to the Four Corners region, including serving as the electric utility for most Hopi residents and operating the Four Corners Power Plant on the Navajo Nation that plays an important role in serving Arizonans with reliable energy. Funds will go to San Juan United Way and The Hopi Foundation to support ongoing emergency response efforts and provide critical assistance to residents impacted by the flooding.

"The Four Corners region is home to APS customers, employees and their families, and the Navajo and Hopi communities are facing a serious and evolving situation, and we want to support them," said Jacob Tetlow, APS Chief Operating Officer. "I started my career working at APS’s Four Corners Power Plant and know firsthand how closely neighbors look out for one another there. We hope this contribution helps provide immediate assistance to families as community members and organizations on the ground continue working together to respond.”

“APS has been a valued partner of San Juan United Way for many years, and their support during this disaster is another example of what it means to truly invest in the communities you serve,” said Cathryn Abeyta, San Juan United Way Executive Director. “We’re hearing from families about what they’re facing and where help is needed most. This funding will help us respond to those needs and direct resources where they’ll make the greatest impact, especially as the challenges of recovery become clearer in the weeks and months ahead.”

San Juan United Way is connecting families with available resources through its 211 service and identifying needs as they emerge. The Hopi Emergency Response Team is also providing critical assistance to families and villages impacted by the flooding, including roof repairs, road assistance and other recovery needs.

“The Hopi Emergency Response Team extends its sincere gratitude to APS for their generous donation in support of flood relief efforts,” said Paul Saufkie, Hopi Emergency Response Team Incident Commander. “This contribution will also help strengthen our communities’ preparedness for future inclement weather and support efforts to protect lives and property. We are grateful for APS’s contribution as we continue working together to support affected families, prepare for future weather events, and build safer, more resilient communities.”

The APS donation is funded by shareholder dollars and will not impact customer rates.

PHOENIX – While monsoon season officially ended Sept. 30, last week’s storms were a reminder that preparing for severe weather is a year-round job. Those same efforts helped Arizona Public Service (APS) keep customers cool, connected and safe this summer while meeting unprecedented energy needs.

“Customers count on us to deliver reliable electricity when it matters most,” said Jacob Tetlow, APS Chief Operating Officer. “Earning that trust requires year-round planning and preparation long before the hottest days, wildfire conditions or monsoon storms arrive. This year, APS employees served record demand, helped safeguard communities from wildfire risk and restored power quickly and safely after strong storms impacted our system.”

Meeting Unprecedented Demand with Reliable Service

APS customers set a fourth consecutive peak energy demand record this summer, reaching 9,166 megawatts at 6:22 p.m. Aug. 2. Long-term planning backed by APS’s ‘all of the above’ approach to generation resources, 24/7 grid operations, and customer programs, helped meet historic energy use throughout the summer season.

APS served customers with reliable energy through a balanced mix of nuclear, natural gas, coal and significant renewable resources, protecting against service disruptions by reducing dependence on any one resource type. Additionally, a record 101,000-plus customer thermostats supported grid reliability through APS Cool Rewards, a smart thermostat demand-response program, and other energy saving initiatives. Together, those programs provided capacity equivalent to the output of a small power plant (about 160 megawatts).

Reducing Wildfire Risk Through Preparedness and Technology

APS advanced its comprehensive wildfire mitigation work during a year when fire risk arrived early in Arizona. The company activated its first Public Safety Power Shutoff (PSPS) in April, temporarily shutting off power in limited areas when extreme fire weather increased the risk to communities. The April PSPS activation helped safeguard roughly 5,800 customers, with a second activation in June protecting approximately 8,000 customers while wildfires burned across the Southwest.

The fire mitigation team used high-definition cameras, advanced fire modeling software and more than 250 weather stations across Arizona to monitor and reduce wildfire risk. APS also expanded its network of artificial intelligence smoke-detection cameras positioned on mountaintops to help identify fires early and support faster coordination with emergency responders. More than 70 AI cameras provide around-the-clock awareness for APS and public safety partners.

Restoring Power Quickly After Monsoon Storms
When monsoon storms arrived, APS crews were ready to respond. Back-to-back days of severe storms in the Phoenix metro area on Aug. 8 and 9 damaged 152 poles. APS sent 45 crews to the hardest hit areas, working quickly and safely to get the lights back on for any customers impacted by the severe weather.

Overall, APS replaced 361 storm-damaged poles throughout the state this summer, above the company’s average of 326 storm-damaged poles since 2015. Preparation before the season – including targeted grid upgrades, strategically staged materials and equipment, predictive maintenance tools, and smart grid technology – helped reduce outage impacts. Crews also strengthened the grid by replacing damaged wood poles with steel poles where possible to build greater resilience against future storms.

“As Arizona’s energy needs continue to grow, safety and reliability remain foundational to everything we do at APS,” Tetlow added. “Our customers are at the center of that work. I’m proud of the preparation our employees put in throughout the year and how they came together to serve customers safely and restore power through summer’s most challenging conditions.”

PHOENIX – Arizona Public Service (APS) will credit customers more than $33 million next month, saving the typical residential customer about $14 on their November bill. The savings will be applied automatically through the Environmental Benefits Surcharge on their bill. Customers do not need to take any action to receive these savings. The Arizona Corporation Commission approved APS’s application for the credit at its Open Meeting Oct. 7.

The credit comes in part from the success of the Green Power Partners program that allows APS to sell renewable energy credits to participating businesses and return the revenue to customers. The funds generated by the Green Power Partners program help ensure customers benefit while APS continues renewable energy initiatives and programs to support Arizona's growing energy needs.

For a typical residential customer using approximately 1,050 kilowatt-hours (kWh) per month, the total bill savings will be about $14 on their November bill. The exact amount will vary based on customers’ energy usage. The credit also applies to business customers, who could see savings of several hundred dollars or more on their November bills depending on their energy use.

APS also offers bill assistance, energy-saving programs and flexible payment options for customers who need help managing their monthly costs. Visit aps.com/assistance to learn more.

The Bottom Line
APS is ensuring that residential and small- and mid-sized business customers are not paying for data center power usage. When extra-large energy users, like data centers or manufacturers, come to Arizona, APS requires them to pay for the infrastructure and power needed to serve them. Our approach has been and continues to be clear: growth pays for growth. Learn more about our Pledge for Responsible Energy Growth here.

The Facts
Recently, 12News aired a series of stories alleging that costs have shifted from data center customers to residential and small- and mid-sized customers. This is not true. The third-party analysis cited by 12News reaches false conclusions inconsistent with standard utility ratemaking, which is misleading and harmful to APS customers.

There are many ways that costs are recovered through rates. One of those ways is a Power Supply Adjustor (PSA) which covers what APS pays for fuel and purchased power. It is part of the overall cost of energy and noted as a separate line item on customer bills. Importantly, APS does not make a profit from these costs; charges are passed on to customers without markup.

The 12News analysis focuses on the PSA alone and it oversimplifies a complex issue and assumes sales growth alone caused higher fuel costs. That’s not how the PSA works, and the analysis ignores the many factors that actually drove higher fuel and power costs, many of which have nothing to do with extra-large load customer growth. Leading factors included: higher fuel and purchased-power prices, resource retirements and contract expirations, increased energy demand across the board, record summer weather and ensuring the highest reliability standards.

Moreover, despite representing only a part of the overall increase in costs, the fact is that during the period covered by the 12News analysis, extra-large customers paid more through the PSA than APS’s total increase in fuel and purchased-power costs over that same period.

Our Proactive Approach
As demand continues to grow, we are proposing to evolve our rate structures to ensure that growth continues to pay for growth. This includes:

• Changes to ensure that the cost of new power purchase agreements needed for growth among extra-large customers are directly assigned to these same customers.
• A 45% base rate increase for extra-large customers to ensure they’re paying their full costs.
• Structures that would allow costs to be reviewed and assigned more directly as growth occurs on an annual basis, ensuring that extra-large customers’ rates are being updated to reflect the costs they are causing.

These issues are being reviewed through the Arizona Corporation Commission’s public and transparent rate case process.

Arizona’s population and energy demands continue to grow, increasing the need for a balanced mix of resources that can deliver power when customers need it most. Add in extreme summer temperatures and record-setting peak demand, and maintaining a resilient electric grid becomes even more important.

That’s where Four Corners Power Plant comes in. For more than 60 years it has reliably served APS customers, providing around-the-clock power to homes and businesses. While APS continues investing in new resources and technologies to meet the state’s rapid growth, existing generation remains an important part of maintaining reliable and affordable service. Because Four Corners is an existing resource, it remains a cost-effective option and is a key factor in APS’s plans to continue operating the plant beyond 2031.

Four Corners complements APS’s growing portfolio of energy resources, including renewable energy and battery storage. We continue to integrate clean energy resources into our portfolio, which also helps support Arizona’s growth and will continue to play an important role in meeting customers’ needs.

The future of Four Corners will continue to be evaluated through APS’s integrated resource planning process, which shows operating Four Corners beyond 2031 could result in a meaningful reduction in costs to customers compared with the modeled 2031 retirement scenario. The plant’s lease with the Navajo Nation allows operations through 2038, and future decisions will be guided by what best serves customers while maintaining reliability and affordability through a balanced energy mix.

Located on the Navajo Nation in New Mexico, Four Corners Power Plant is the last remaining coal-fired power plant in APS’s generation portfolio. The plant’s two units provide approximately 1,540 MW to the grid. APS owns 63%, or about 970 MW, and the plant employs about 250 APS employees.

Continuing to operate Four Corners also supports the Navajo Nation economy, where the plant is an important employer and economic contributor. APS values its long-standing relationship with the Navajo Nation and will continue working with stakeholders in the region as future resource decisions are made.

Bottom line: APS is planning for Arizona’s energy future as the state continues to grow. Keeping Four Corners Power Plant operational helps support reliable, affordable service while APS continues adding new resources to meet customers’ needs.

On August 25, two Phoenix teachers walked into their classrooms expecting a typical school day. Instead, they were greeted by Arizona Diamondbacks player Ryan Waldschmidt, D-backs Legends Racers and APS representatives as each teacher had been randomly selected to receive a $500 prepaid card to use toward classroom supplies through the APS Supply My Class program.

The celebration at Clarendon Elementary School gave students a front-row seat as their teachers learned they were among 500 K–12 educators randomly selected across APS’s service territory this year. The prepaid cards will be used for supplies that support student learning, from everyday classroom essentials to materials for hands-on lessons.

“Everything I do is for these students, so to see how excited and happy they are right now is wonderful,” said teacher Kayce Kahf. “I’m going to do some flexible seating in my room, and I want to get book sets to pass out to the class as well. I am very grateful and I couldn’t be more appreciative of APS and the D-backs for supplying my classroom."

Waldschmidt visited each class alongside APS Strategic Partnerships Manager Maria Morales and D-backs legends racers Randy Johnson and Mark Grace, and he spoke with students about the importance of teachers.

“Your teacher is going to put this money to great use for you guys, so make sure you always listen, pay attention and show her respect,” Waldschmidt said. “She cares a lot about you and your future.”

Helping teachers bring learning to life

Teachers across Arizona often go above and beyond for their students, including purchasing classroom materials with their own money. APS launched Supply My Class in 2018 to help ease that burden and give educators more resources to create engaging learning experiences.

“Supporting education is very important to us at APS, and we are so grateful for all you do to shape these young students,” said Morales told the teachers during one of the surprise visits. “We are honored to celebrate you and other teachers who work tirelessly to support the success of the next generation.”

Now in its ninth year, the program has provided funding to more than 6,000 teachers. This year, 500 qualifying teachers at K–12 public and public charter schools in APS service territory were randomly selected to receive a $500 prepaid card. The visit to Clarendon Elementary kicks off a series of teacher surprises around the state over the next several weeks.

APS Supply My Class applications are closed for this cycle. However, K-12 educators within APS service territory are encouraged to visit aps.com/education for all the ways APS supports teachers and students throughout the year.

The APS Supply My Class program is funded by APS shareholders and is not included in customer rates.

Arizonans earning average wages may be eligible for as much as $640 or more in assistance to pay their Arizona Public Service (APS) bills through a state program called Power AZ, while funding lasts.

The temporary program is an initiative from Gov. Katie Hobbs administered by the Arizona Department of Economic Security (DES). It is unique because most bill-assistance programs are available only to families who are earning less than average income, while Power AZ is available to families earning median wages.

Who is eligible for Power AZ?

Single people living alone can earn about $4,890 a month and still qualify for assistance under the state’s guidelines, while a family of four with monthly income of about $9,400 can qualify.

Power AZ is designed for people who historically have not been able to take advantage of such programs and can help those who are experiencing new, unexpected hardships,” said Danielle Evans, Chief Customer Officer for APS. “Many people may not realize they meet the eligibility requirements because they think they earn too much for bill assistance, but those are precisely the customers this program was created for.”

The benefit amount is as much as $640 per year for those who qualify. People facing a crisis may be eligible for an additional $500 in one-time support. The funds are available for a limited time, and may expire in September. Customers can apply for Power AZ at the DES website.

The online application also automatically screens eligibility for the long-standing Low Income Home Energy Assistance Program (LIHEAP) that is designed to help households with income at or below 60% of the state median income, or 150% of federal poverty guidelines. Applications will be reviewed for eligibility in either program. Customers can only get assistance through one of the programs in a 12-month period. 

APS Customer Assistance and Support

In addition to Power AZ, APS offers customers a variety of ways to manage their bills:

• Energy Support Program: Customers may qualify for monthly discounts of up to 25% or 60% on their energy bills based on income.  Visit aps.com/assist.
• Crisis Bill Assistance: Customers facing temporary financial hardships, like a sudden reduction in income or unplanned major expense, may qualify for up to $1,000 per year in bill assistance based on income. This support is available through APS and our nonprofit partners. Customers can start the process by visiting aps.com/assistance or calling APS.
• APS CARE (Crisis Assistance Relief Effort): Customers can receive up to $500 in bill assistance in partnership with The Salvation Army, regardless of income. Visit aps.com/care.
• Flexible payment arrangements: An option for those who need more time to pay their balance. Visit aps.com/arrangement.
• Preferred due dates are available for customers to select the date they’d prefer to pay their bill each month, aligning better with their schedule.
• Safety Net: Friends and family can be designated to receive a copy of a customer’s bill to keep an eye on the account and ensure their loved one does not fall behind on payments. Enrollment is available through the customer’s online account or by phone. Visit aps.com/safetynet.
• Guest Roles: Customers can authorize someone they trust to have access to or help manage their APS account online to understand how they are using energy, manage their rate plan and make sure they don’t miss any payments. This can be set up through the customer’s APS.com account dashboard.
• Budget Billing can help take out the seasonal swings of summer billing by leveling payments throughout the year. This makes it easy for customers to know what their APS bill will be every month. Visit aps.com/budgetbilling.

Arizona Public Service (APS) President and CEO Ted Geisler outlined APS’s Pledge for Responsible Energy Growth this week as part of broader remarks shared with Arizona community leaders gathered for the 2026 League of Arizona Cities & Towns Conference. The pledge reaffirms APS’s longstanding principles for protecting customers while serving new companies and industries investing in Arizona.

“Growth should pay for growth. It's that simple. When a data center or manufacturer comes to Arizona, they pay the cost of the infrastructure needed to serve them, and those investments help to cover shared grid costs that existing customers would otherwise carry,” said Ted Geisler. “Done right, new growth doesn't threaten affordability for Arizona families and businesses. It helps protect it.”

The APS Pledge for Responsible Energy Growth is grounded in three foundational principles:

• Safeguarding Reliability: APS will not connect new extra-large customers to the grid faster than it can reliably support. Every extra-large customer agreement is designed with built-in safeguards to protect other customers, including operational and contractual protections that support sufficient, reliable operation and help APS to manage the energy grid during periods of peak demand.

• Protecting Customer Rates: New extra-large energy users will pay the costs associated with serving their energy needs and growth, including investments and upgrades in generation, transmission, distribution and the grid. Those costs and financial risks will not be shifted to residential and business customers. Furthermore, as extra-large customers fund upgrades needed to serve their growth, their investments will also help to cover shared infrastructure costs that otherwise would be paid by existing customers.
• Preserving Capacity: Before committing to serve new extra-large customers, APS will preserve enough capacity to meet the needs of Arizona’s current and future homes, small and larger businesses, schools, hospitals, and communities. Connecting and serving residential and business customers will remain our company’s top priority.

“These three principles aren't aspirations. They're standards we build into our agreements with extra-large customers,” Geisler continued. “Arizonans should be able to welcome the jobs, investment and opportunity coming to our state with confidence that their energy needs come first and their rates are protected. That's our pledge.”

As record setting heat impacted Arizona and surrounding states, APS customers set a new all-time peak energy demand record on Sunday, Aug. 2, 2026 using 9,164 megawatts (MW) between 6 and 7 p.m., according to preliminary figures. One MW of energy is enough to serve about 160 Arizona homes.

Peak demand is the period of time when customer energy use is at its highest. The new peak surpasses the previous record of 9,053 MW, set on July 24, 2026.

Despite the increased demand driven by continued extreme temperatures across Arizona, APS maintained reliable service for customers. APS’s balanced energy mix, regional market access, generating resources and operational preparedness enabled APS to meet customer needs while maintaining appropriate reserves. "Arizona's hottest summer days are when preparation matters most," said Tim Rusert, APS Director of Power Supply Resources. "Successfully serving this level of demand is the result of deliberate planning, ongoing investments and the year-round work of APS employees who maintain and operate APS's electric grid. Those preparations enabled us to successfully meet customer energy needs during this period of sustained high temperatures.”

Additional information about APS's preparation for periods of high energy demand is available in the July 27 news release.

As sustained high summer temperatures pushed energy use to a new high late last week, Arizona Public Service (APS) customers counted on reliable power to keep homes, businesses and air conditioners running. And APS delivered, as customers set a new all-time peak energy demand record on Friday, July 24, 2026, using 9,053 megawatts (MW) between 5:00 and 6:00 p.m., according to preliminary figures. The previous record was set Aug. 7, 2025, when APS customers’ energy use hit a peak of 8,648 MW. One MW of energy is enough to serve about 160 Arizona homes. 

As high temperatures impact many parts of the country, the U.S. Department of Energy issued an emergency order on July 26 directing the deployment of backup generation resources in a number of states to ensure grid reliability. The order does not apply to Arizona Public Service and does not impact APS customers. APS has sufficient generation and reserves to serve our customers throughout the state. 

APS provides top-tier reliable service to customers throughout the year, supported by investments, years of planning and year-round preparation to keep the lights on and air conditioners running during Arizona’s hottest days. Ensuring this level of reliability requires proactive infrastructure maintenance, grid upgrades, resource planning and power plant readiness that strengthen the reliability and resiliency of the electrical system. 

APS crews, supported by a team of meteorologists and other experts, regularly inspect, maintain and upgrade critical infrastructure, prepare equipment and generating resources for periods of high demand, and train year-round for storms and emergencies. Together, these efforts ensure customers have safe, reliable power when they need it most. 

Peak demand is the period of time when customer energy use is at its highest. This is the fourth consecutive year APS customers have set a peak energy use record, reflecting continued growth across Arizona as more people move here, new businesses open and the economy expands. This growth requires APS to invest more than $2.5 billion a year in upgrades, operations and maintenance of the electrical system to provide customers with top-tier reliability. 

APS is strengthening Arizona's energy future with a balanced mix of resources designed to support reliability while meeting growing energy demand. Flexible natural gas generation helps APS integrate more solar, wind and energy storage on the grid, ensuring energy is available when customers need it most, especially during Arizona's hottest days. Nuclear energy also remains a critical component of APS's portfolio, supported by ongoing investments in Palo Verde Generating Station and the continued evaluation of future nuclear generation opportunities.

A few new classroom supplies can go a long way. They can turn a math lesson into a hands-on activity, help students see a concept click in real-time and give teachers more ways to bring learning to life.

That is the idea behind Arizona Public Service’s (APS) Supply My Class program, which helps K-12 public school and public charter school teachers within the utility’s service territory purchase supplies that support student learning, creativity and confidence.

Now entering its ninth year, the APS Supply My Class program provides $500 prepaid cards to qualifying teachers to buy classroom supplies.

For many teachers, that funding helps cover much more than pencils, notebooks and markers. It enables the creation of more engaging, interactive classrooms where students can participate, collaborate and connect what they are learning to everyday life.

Previous Supply My Class winner and middle school teacher, Jodie Ray-Marlowe, used the funding to purchase supplies that have helped to increase the active participation in lessons among her students at Desert Shadows Middle School. This included practicing concepts in real time and connecting math to daily decisions like comparing prices, calculating discounts, understanding rates of change and evaluating cell phone plans or budgeting options.

“The impact extends far beyond supplies,” Mrs. Ray-Marlowe shared. “This support has helped make it easier to create lessons where students can explore ideas, work through real-world examples, feel more capable as math learners and build stronger connections to the math they use every day.”

Since launching in 2018, APS has awarded funding to more than 6,000 teachers to buy basic school supplies, refresh their classrooms and support student success.

“Teachers have an incredible ability to turn everyday materials into meaningful learning moments,” said Tina Marie Tentori, Director of Community Affairs for APS. “The Supply My Class program is one way we can support educators who are helping students build confidence, think creatively and prepare for the future.”

PHOENIX – During this summer stretch of extreme heat, Arizona Public Service (APS) recognizes the skilled lineworkers who perform some of the most challenging and essential work in the energy industry. July 10 is National Lineworker Appreciation Day, a time to honor the people who safely build, maintain and restore the electric system that keeps power flowing across Arizona.

APS lineworkers are part of a 24/7 operation and are ready to respond when customers need them most, working in record heat, repairing damage after monsoon storms, traversing rugged terrain and through cold and snowy winter weather in Arizona’s high country. They help strengthen the energy grid before extreme weather arrives and respond quickly and safely to restore power when outages occur.

“Our lineworkers are built for the moment, whether it’s the test every Arizona summer presents or navigating winter storms in the northern region,” said Mackenzie Rodgers, Vice President of Transmission and Distribution Operations. “It is highly technical, physically demanding work that requires teamwork and steady judgment regardless of circumstance. They show up with skill, focus and a safety-first mindset to every job, both for each other and on behalf of every community APS serves.”

APS lineworkers and the teams who support them play a critical role in keeping Arizona safe and connected. Their efforts reflect APS’s commitment to serving customers and communities across the state.

“That work is grounded in a deep sense of responsibility to the people and places we serve,” said Tony Tewelis, Senior Vice President of Energy Delivery and Large Customer Projects. “Arizona is growing quickly and our crews are helping to ensure customers have the safe, reliable power they need today and well into the future.”

The evidentiary hearing in the Arizona Public Service (APS) rate case has concluded, marking an important milestone in the Arizona Corporation Commission's (ACC) review of APS's application to update rates. Similar to what you might picture in a court case or trial, during the months-long hearing, APS and other parties presented testimony, introduced evidence and responded to questions on the record regarding APS’s proposal and the investments made to continue providing reliable electric service for customers.

Even though the hearing has ended, the rate case is not finished, and customer rates are not changing now. The process includes several more steps before the Arizona Corporation Commission reaches a final decision.

What Happens Next?
Now that the hearing is over, the ACC's Administrative Law Judge (ALJ) will review the testimony, evidence and legal arguments submitted during the case and develop a recommendation for the Commission to consider. That recommendation is called a Recommended Opinion and Order, or ROO. It may take months for the ROO to be issued. After the ROO is issued:

• APS and other parties to the case will have an opportunity to respond and suggest changes to the ROO.
• The Arizona Corporation Commission will review the ROO and consider whether any changes, or amendments, are needed.
• The Commission will hold a public meeting, discuss the recommendation and vote on a final decision.

Understanding the Rate Case Process
It is important to understand that APS does not simply ask for a rate change and receive automatic approval. A rate case is a detailed public review process that takes well over a year. APS filed this case more than a year ago, and a final decision is expected later this year.

This process is designed to ensure a thorough, transparent and fact-based review of APS's rate adjustment application to give the Commission a complete picture before it decides whether to approve the request. A final decision from the ACC is expected later this year.

Why is APS requesting a rate increase?
Current APS rates are based on costs from five years ago. Inflation and rising expenses mean those rates no longer cover what it takes to operate and strengthen the electric grid today. By updating rates to reflect current costs, APS can continue to provide customers with the top-tier reliability they need and expect, especially during Arizona’s long, hot summers.

As a regulated utility, APS must look backward to adjust its rates based on the actual costs it paid to serve customers in 2024 and 2025. This ensures rates more accurately match the true costs of providing electric service to customers. For context, 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. (See graphic on below.)

How does the rate proposal protect affordability and reliability for APS customers?
In addition to ensuring a reliable energy grid and upgrading equipment, the rate case introduces measures to further support customers. Amid rising costs for infrastructure, equipment and materials, APS is anticipating unprecedented growth within its service territory. To protect residential and small business customers, APS is making sure new large energy users, like data centers, continue to pay their full cost of service.

The plan proposes a rate increase of more than 45% increase for data centers and updated cost allocation for system investments, like power plants, so growth-related costs are assigned to the customer classes driving expansion. APS’s application also outlines a formula rate, under which future costs (e.g., infrastructure, fuel, etc.) are reviewed annually and allocated to the customer group responsible for those costs, such as data centers.

What about summer electric bills?
With the arrival of hotter weather, most customers naturally use more energy as air conditioners work harder to keep homes cool. That higher energy usage in the summer drives higher bills for most customers. APS’s rate proposal will have zero impact on customer bills this summer. It’s important for customers to know they have options to manage their bills and lower their costs. For example, customers can compare rate plans by using APS’s rate comparison tool at aps.com/compare. Customers can visit aps.com/save for tips to save energy.

Customer Support and Resources
APS helps connect customers facing financial hardship to programs and resources that can make a difference. The Crisis Bill Assistance program provides up to $1,000 for those in need. Eligible customers can also receive monthly discounts of up to 25% or 60% through the APS Energy Support program. Learn more at aps.com/assistance or by calling the 24/7 Customer Care Center. APS advisors are available in English and Spanish at 602-371-7171 or 800-253-9405.

Arizona Public Service (APS), Salt River Project (SRP) and Tucson Electric Power (TEP) continue to work together to explore adding nuclear generation in Arizona, including through a preliminary siting study now underway.

New nuclear generation will take time to develop, which is why it’s essential that Arizona’s leading energy providers begin these initial steps now. APS, SRP and TEP are utilizing industry guidance to evaluate locations throughout Arizona, including sites that have been used for coal-fired power generation. The study will use a phased screening methodology to narrow down areas in the state to a short list of leading candidates, culminating with the selection of a preferred site. 

As part of the site selection process, the energy providers will begin stakeholder engagement and community outreach, and plan to hold community meetings near potential nuclear generating sites in late 2026 to share information and seek feedback.

The siting study, which is expected to be completed within the next six months, is foundational to subsequent steps in the nuclear planning process. Once the study is complete, the energy providers will evaluate technical, financial and other factors before determining if they will develop an Early Site Permit (ESP) application. If an ESP application is pursued, the companies would then decide whether to submit the application to the U.S. Nuclear Regulatory Commission for approval.

APS, SRP and TEP recently received notice they were not awarded the U.S. Department of Energy grant they applied for in early 2025 to support this work. They will continue to work together to explore future funding opportunities to help mitigate the costs of evaluating potential new nuclear generation.

The joint nuclear exploration effort comes as Arizona’s electricity needs continue to rise, driven by population growth and economic expansion. APS, SRP and TEP all set peak-demand records in 2025, underscoring the need for continued long-term planning and reliable generation. The energy providers are working proactively to ensure the grid can keep pace with rising demand, while also ensuring safe, reliable and sustainable electricity for customers.

The companies have not made a final decision to build a new nuclear plant in Arizona, and no nuclear technology has been chosen for the potential project. Both small modular reactors and larger reactor designs remain under review. Any future project would depend on industry progress on cost and schedule predictability, supply chain development and financing considerations. In the long term, the companies will prioritize nuclear technologies that are commercially proven as reliable; have been safely and successfully deployed elsewhere; and are provided by suppliers with strong operational records and demonstrated commercial viability.

New nuclear generation opportunities will be discussed at an Arizona Corporation Commission workshop hosted by Commission Chairman Nick Myers and Commissioner René Lopez on Thursday, June 25, 2026. The workshop will bring together energy providers, policymakers and industry stakeholders to further discuss the role nuclear energy can play in resource planning.
