APS's time-of-use rates divide the day into peak (highest cost), mid-peak, and off-peak (lowest cost) periods. Peak hours are typically weekday afternoons when demand is highest. Off-peak hours are nights, early mornings, weekends, and holidays when demand drops.
APS may offer multiple TOU plan options with different peak/off-peak hour definitions and rate differentials. Some plans have a larger spread between peak and off-peak rates, offering more savings potential for customers who can shift their usage. Compare plans based on your typical daily schedule.
Shift laundry, dishwashing, and EV charging to off-peak hours. Pre-cool your home before peak hours begin. Use a smart thermostat to automate temperature adjustments around peak periods. Customers who shift 50%+ of usage to off-peak hours typically save 15-25% compared to flat-rate plans.
