Ever wonder where the money from your energy bill goes? 💡 Every dollar helps support the reliable service you count on—from producing and delivering energy to maintaining and improving the grid. Watch to see how it all adds up.

APS Delivers Reliable Service Through Record Summer Demand Year-round preparation supported customers in extreme fire weather and during storms 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.” aps.com/newsroom

APS customers to receive bill credit in November 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

We’ve served Arizona for 140 years, in the towns and communities where we live. As Arizona experiences extraordinary growth, our responsibility to protect customers has never been more important. That’s why APS is ensuring that residential and small-business customers are not paying for data center power usage – and why we’re taking steps to make sure they won’t in the future. Unfortunately, recent @12News reporting makes false and misleading claims about data center costs. The simple truth is that our rate structures are working as designed to avoid cost shifts. Get the facts here: tr.ee/T2mhGw

With misleading claims circulating about whether data center growth is affecting energy bills, we know our customers want clear, accurate information. The simple fact is: APS is ensuring that residential and small-business customers are not paying for data center power usage. When a data center or manufacturer comes to Arizona, APS is requiring that they pay for the infrastructure and power needed to serve them.

Assistance Available for Middle Income Families to Pay APS Bills Power AZ assistance is available for a limited time 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.  Visitaps.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.

APS CEO Reaffirms Customer Protections in Pledge for Responsible Energy Growth 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.” Get more information at aps.com/pledge

We’re grateful to our customers for their patience as our crews responded to last night’s storms across the metro Phoenix area. 💛 At the peak of the storm around 11 p.m., approximately 12,000 customers were without power. Our crews responded right away and restored service to most affected customers in less than two hours. The remaining outages were restored throughout the morning. Summer storm season is not over. While we work around the clock to provide reliable service no matter what Mother Nature brings, outages can still happen. If your power does go out, visit aps.com/outagecenter for map, restoration times and safety information, all in one place.

This power line came down with enough force to cut a street sign in half — a striking reminder of why it's important to treat every downed power line with caution. Even if a line isn’t sparking, making noise or appears to be inactive, always assume it is energized. If you see a downed power line: ⚠️Stay at least 100 feet away and keep others away. 📞 Call 911 first, then call APS at (602) 258-5483 in metro Phoenix or (800) 253-9408 in other areas. 🚫 Never touch, move or drive over a downed power line. Your safety comes first. Give damaged electrical equipment and our crews plenty of space to work.

After several days of severe storms, we’re grateful to our customers for their patience and our employees for their work behind the scenes as we restored power. Strong storms Sunday and Monday night damaged more than 100 poles across central and southwest Arizona. At the height of Sunday night’s storms, approximately 23,000 customers were without power. All customers impacted by the storm have service as of Wednesday. Teams worked around the clock to restore service safely and as quickly as possible. We know outages can disrupt your day and create added challenges, especially during the heat. Thank you for your understanding as our teams worked to get the lights back on. 💛

We know being without power is especially challenging during the summer heat, and we appreciate the patience of customers who are still waiting for service to be restored. Since Sunday's storms, APS crews have been working around the clock to bring power back, and they'll keep going until every customer affected has power restored. On Sunday, Aug. 9, a strong storm moved through the Phoenix metro area. More storms and outages followed late last night and into this morning. Approximately 23,000 customers have been impacted by the storms with approximately 250 remaining without power. While weather conditions have improved, additional storm activity is possible later today. As repairs continue, please give our crews plenty of room to work. For your safety, if you see downed power lines, please stay away, call 911, then call APS at 602-371-7171 (metro Phoenix) or 800-253-9405 (other areas). And secure outdoor items such as umbrellas, trampolines and portable awnings that could become airborne and cause outages in strong winds.
