    What are time-of-day price plans?

    At certain times of the day, many people and businesses in the Valley are using energy, which puts pressure on the power grid. SRP’s time-of-day plans offer price breaks for customers who can shift energy use outside of those high-demand, or “peak,” hours. That’s a win for the power grid and your wallet.

    SRP offers multiple time-of-day price plans, so you can create a schedule that works for you and lowers your energy costs.

    How it works

    Save money when you shift your energy use outside of peak hours, Monday through Friday. You’ll get lower energy prices during off-peak hours, plus weekends and holidays Open tooltip to learn more., all year long.

    Easiest way to save: Precool before peak hours

    Nearly half of the energy used in your home goes to heating and cooling.* To save big, install a programmable or smart thermostat and precool your home before peak hours begin.

    1. Three hours before peak hours begin, set the thermostat to three degrees below your preferred temperature.
    2. When peak hours begin, set the thermostat to three degrees above your preferred temperature to keep the air conditioner from running too much.
    3. When peak hours end, set the thermostat back to your preferred setting.
    Some homes may require more time to precool/return to preferred settings. Adjust the temperature and timing based on your home’s size, age and building materials and your comfort level. Some smart thermostats learn your schedule and are programmed automatically. You may need to turn off this feature to precool.

    Install a smart thermostat to make precooling easy

    With a smart thermostat, you can set a schedule to adjust the temperature automatically. You can also adjust the temperature anytime, from anywhere, using your smartphone.

    Save on a smart thermostat when you shop the SRP Marketplace. (Be on the lookout for sales and rebate offers throughout the year!)
