Residential customers in Utah have the option of switching from basic service to Rocky Mountain Power’s Time of Day option. Time of Day gives you more control of how much you spend on electricity. The program rewards customers who can move a substantial portion of their power usage away from summer “on-peak” hours – that’s when demand for electricity is at its highest and when it is most expensive to get the power to our customers. Last year, we made changes to the Time of Day option to increase the number of off-peak hours available to customers and make it easier to track savings each month.

Under the Time of Day option, the price you pay for electricity depends on when you use it. During the summer, May through September, the price of the energy you use is divided into two time periods – on-peak and off-peak . On peak-hours are Monday through Friday from 1 to 8 p.m. Off-peak hours are all other hours. Some holidays that fall on weekdays are also considered off-peak hours all day.

With Time of Day, your basic service rates still apply. However, under Time of Day, the rate you would pay is 1.4014 cents less than your basic service rate (Schedule 1 or Schedule 3) for each kilowatt-hour (kwh) of electricity used during off-peak hours. You would pay 4.3762 cents more than the basic service rate for each kwh of electricity used during on-peak hours. 

Most customers would need to limit their on-peak usage to less than 24 percent of their total electricity usage, in order to save money on this option. To record the time periods you use electricity for this program, installation of a special Time of Day meter will be required. Enrollments are limited to the first 1,000 participants.

As you review your electricity use, you can consider how much electricity common household appliances use as a guide. Keep in mind that appliances like refrigerators and freezers use electricity around the clock. And, other electronics continue to use small amounts of electricity when they’re plugged in, but not in use—computers, printers, clock radios and microwaves are all examples.

As you think about how to shift electricity usage to lower-priced off-peak times, you should also consider how you can reduce the overall amount of electricity your household uses each month. Check out our energy efficiency tips and see how you can save electricity and money.
