APS Electric Rate Increase in 2026: What Customers Need to Know

Many Arizonans are bracing for even higher electricity bills in 2026, as utility regulators consider a 16% bill increase request for Arizona Public Service (APS) residential customers.

If approved as proposed, the average household would see its bill increase by $20 a month as soon as July 2026.

At-A-Glance: 2026 APS Rate Impact

Arizona’s largest utility has filed a major rate case with the Arizona Corporation Commission (ACC). If approved, residential customers will see a double-digit jump in their monthly bills starting in the second half of 2026.

Why Are APS Rates Going Up?

APS claims the increase is necessary to recover $1.7 billion in recent investments and to account for economic changes since their last rate adjustment. Key justifications provided in the filing include:

• Grid Modernization: Significant spending on poles, wires, and substation upgrades to maintain “top-tier reliability.”
• Extreme Weather Resilience: Increased costs for vegetation management and wildfire mitigation to protect infrastructure during Arizona’s record-breaking heatwaves and monsoon seasons.
• Economic Growth: Preparing for higher peak energy demand driven by population growth and high-usage data centers.
• Inflation: APS notes that the cost of critical parts, like transformers, has risen as much as 64% since 2021.

The “Formula Rate” Overhaul: Are Yearly Rate Hikes Coming?

The most impactful part of the 2026 proposal isn’t just the one-time $20 jump—it’s the request to switch to “Formula Rates.”

Under traditional rules, a utility must undergo a massive, multi-year public audit (a “rate case”) before raising prices. APS is asking to bypass this process for the next five years, allowing them to adjust rates every single year based on their own internal cost studies. Consumer advocates warn this would lead to “compounding” price hikes with less public oversight and fewer opportunities for customers to fight back.

How Will The APS Rate Hike Impact Your Bill?

A $20 monthly increase would add $240 to the average Arizonan’s annual electricity costs, or at least an additional $2,400 over the next 10 years.

If the formula rate plan is approved, this number could climb much higher as small, incremental yearly increases stack up. By 2036, a family could easily be paying thousands more than they do today just to keep their air conditioning running during the summer.

How to Offset the APS Rate Hike

With APS rates poised to rise (again), many Arizonans are looking to solar and battery storage to take control of their energy costs.

• Lower your electricity costs: Rooftop solar can power your home at a lower cost per kilowatt-hour than the utility grid.
• Hedge against energy inflation: While utility rates rise unpredictably over time, solar provides a predictable cost of power.

In addition to new solar financing models that benefit from a federal tax credit, Arizonans can claim a 25% state tax credit worth up to $1,000 for installing solar.
