Is your APS bill jumping even when you try to cut back? In Peoria, those weekday peak hours can sneak up right when you get home and the A/C is working hardest. You want lower bills without sacrificing comfort, and you want a plan you can actually follow. This guide gives you a simple playbook to shift usage, automate smart savings, and tap local rebates so you keep more money in your pocket. Let’s dive in.
APS peak hours, at a glance
For most APS residential Time‑of‑Use plans, on‑peak is 4–7 p.m. on weekdays. If you are on a legacy Saver Choice Plus plan, the window remains 3–8 p.m. Confirm your plan and details on the APS service plan page and your bill’s plan comparison tool. Review current APS plans and hours.
APS shortened the on‑peak window to make it easier to manage and to encourage shifting to off‑peak hours. You will pay more during on‑peak and less the rest of the day. See APS’s TOU transition overview.
Note: Program rules and rates change. Check aps.com for the latest plan details as of October 2025.
Why 4–7 p.m. matters in Peoria
Late afternoons are hot in the Phoenix metro, and cooling demand stays high right when many households return home. That is also when rooftop solar production tapers, so the grid sees its heaviest strain. APS and state regulators emphasize shifting use away from 4–7 p.m. to support reliability and reduce your costs.
Your 4–7 p.m. game plan
Focus on a short three‑hour window. Small changes add up.
- Run the dishwasher, laundry, and oven before 4 p.m. or after 7 p.m.
- Delay pool pump cycles and EV charging until off‑peak hours or weekends.
- Avoid stacking big loads at once during on‑peak, especially if you are on a demand‑based plan.
- Use a smart thermostat to pre‑cool, then hold steady through the peak.
APS offers simple guidance on shifting usage and pre‑cooling. See APS’s FAQ tips.
Pre‑cooling checklist
- Two to three hours before 4 p.m., lower your thermostat a couple of degrees to store cool air.
- At 4 p.m., raise the setpoint slightly and let the system coast through the peak.
- After 7 p.m., return to your normal setting and run other appliances.
As a rule of thumb, each degree warmer you set for cooling can save about 2–3 percent of cooling energy, and smart thermostat scheduling can deliver meaningful savings when maintained. Explore APS’s smart thermostat savings.
Smart tech that pays off
- Smart thermostat. Automate pre‑cooling and on‑peak setbacks, and enroll for rebates. APS reports typical homes can save up to about 15 percent with proper settings, and rebates or marketplace discounts are available. Check the smart thermostat rebate.
- EV charging. Use a Level 2 smart charger and schedule charging off‑peak. APS offers a $250 rebate for qualifying chargers. Learn about APS’s EV charger rebate.
- Smart plugs and timers. Set pool pumps, water heaters with timers, and other loads to avoid 4–7 p.m. See APS’s FAQ tips.
Bigger upgrades and rebates
Target upgrades that cut cooling demand and shift usage.
- AC upgrade and quality install: $200 rebate available, with additional assistance for eligible customers. Proper sizing and installation reduce on‑peak load.
- Insulation and duct sealing: $250 each to keep conditioned air where it belongs and lower peak usage.
- Water‑heater timers: $200 rebate to shift heating to cheaper hours.
- Batteries and storage: APS has piloted residential storage and launched programs like Storage Rewards, which can help reduce on‑peak purchases. Availability changes, so check status.

Pick the right APS plan
Time‑of‑Use can be a great fit if you can shift loads reliably. If your schedule is fixed, a non‑TOU plan may be simpler. Compare options with APS’s tools and the Monthly Plan Comparison on your bill. Compare service plans.
If you are on a TOU plan with a demand charge, manage your peak hour with care. Run one major appliance at a time during 4–7 p.m., and avoid stacking AC, the dryer, and EV charging together. APS also offers tools like a demand limiter and a one‑time demand charge credit in specific cases. Review APS’s peak‑hour tips and demand guidance.
If you have rooftop solar
TOU can complement solar by using midday production and limiting evening purchases. APS also applies a Grid Access Charge for residential generation, which affects monthly bills and payback. Review your system size and charges, and consider storage or grid‑interactive devices as programs expand. Read APS’s public notice on grid access charges.
Need help with bills or heat
If you are navigating a high bill or a heat emergency, help is available. Maricopa County provides utility assistance and heat‑relief resources. Explore county assistance programs and Arizona DES LIHEAP for eligibility and enrollment.
