Tips for saving money on the EZ-3 Price Plan

Use less energy during your EZ-3 enrolled plan hours — either 3–6 p.m., 4–7 p.m.* or 2–5 p.m.* Monday through Friday when energy costs are higher.

Cooling and heating

  • During the cold winter months, set your thermostat between 68 and 70 degrees when you're home and to 65 degrees or lower when you're away. For each degree you lower your thermostat, you can save 2-3% on heating costs.
  • Air conditioning can account for 50% or more of your total summer energy costs. Consider installing a programmable or smart thermostat to automatically control your air conditioner and furnace or heat pump.

    NOTE: Some thermostats offer advanced features that will achieve your set temperature by the time programmed instead of starting at the time programmed. Check the instruction manual or manufacturer's website to verify advanced features.
  • If you don't have a programmable thermostat, during the summer, set your thermostat to 85 degrees when you're away from home. For every degree the temperature is raised above 80, you can save 2-3% on cooling costs. If you do have a programmable thermostat, whether you're at home or away from home, precool your home to save money and stay comfortable.

How to precool your home

  • Set the thermostat temperature three degrees below your preferred setting three hours before your higher-cost hours begin (either 2–5 p.m., 3–6 p.m. or 4–7 p.m. Monday through Friday.) For example, if you are on the EZ-3 3-6 p.m. plan and usually set the temperature to 78 degrees, precool your home to 75 degrees from noon until 3 p.m. while prices are lower.
  • At the start of the higher-cost period, set the thermostat temperature three degrees above your preferred setting so that the air conditioner doesn't run much, if at all, during your three higher-cost hours. For example, if you are on the EZ-3 3–6 p.m. plan and usually set the temperature to 78 degrees, after precooling your home, increase your thermostat setpoint to 81 degrees from 3–6 p.m. while prices are higher.
  • Set the thermostat to return to your preferred setting when higher-cost hours end.**
  • Some homes may require more time to precool and return to preferred settings when higher-cost hours end. You may need to vary temperature and time settings based on your home's size, age and building materials and your preferred comfort level.***

* EZ-3 2–5 p.m. and 4–7 p.m. are pilot time periods that were limited to 10,000 customers each and are no longer accepting enrollments.

** Some thermostats offer advanced features that will achieve your set temperature by the time programmed instead of starting to cool at the time programmed. Check the instruction manual or manufacturer's website to verify advanced features.

*** Precooling guidelines are based on optimum results from "Modeling and Testing Multiple Precooling Strategies in Three Residential Building Types in the Phoenix Climate," an SRP research project in partnership with Arizona State University.

Pool/spa

  • Your pool or spa pump can account for 13% of your home energy use. Install a timer and run your pump only as long as needed each day to keep the water clean.

Appliances and other devices

  • Don't preheat your oven for too long, and turn it off 15 minutes prior to completion. Grill outside or use the microwave to keep the kitchen cool.
  • Avoid running the dishwasher, but if you do, be sure to run it with a full load. Use the "energy-saving" button to save up to 20% on your dishwasher's energy costs. Approximately 12-20% of your annual energy costs are from heating water.
  • Typical households wash and dry nearly 400 loads of laundry each year. Operate your washer and dryer during off-peak hours to save money.
  • Install and set a timer for the electric water heater to prevent on-peak heating. In addition, turning down the thermostat to 120 degrees can save up to $7 a month.
  • Some electronic devices consume energy even when they're turned off. Plug these "vampire" appliances into a power strip that can easily be turned off during on-peak hours.
