Improve Grid Resiliency – Shifting electricity consumption away from peak hours helps increase grid resiliency for everyone in Arizona and reduces the risk of blackouts. Load shifting can save you money and help you avoid expensive time of use rates. But it can also be extremely frustrating.
There are two main benefits of load shifting your electricity consumption. Avoid Time of Use (TOU) Rates – If you're on a TOU rate plan with APS, you pay more for electricity during peak hours (weekdays from 4 pm to 7 pm). By shifting larger loads outside of these hours, you can avoid higher rates and save money. Learn more about APS rate plans.
Load shifting is a load management technique in which large electrical loads are moved from peak electricity demand hours to off-peak hours. When you load shift, you don't use less electricity. You simply move larger loads, like running your clothes dryer or charging your EV, to a different time of day. What Are the Advantages of Load Shifting?
In a household setting, appliances and electronics are considered electrical loads. So, for example, your air conditioner is one load, your refrigerator is another load, and your TV is another load. Load shifting is a load management technique in which large electrical loads are moved from peak electricity demand hours to off-peak hours.
