Utah electric vehicle pricing plan

If you drive a plug-in electric vehicle, you can enroll in our Time of Use rate option. Under this option, the price you pay for electricity depends on when you use it.

You may save money on your bill if you charge your car and use other equipment during off-peak hours. 


  • Utah residential customers who own plug-in electric vehicles.
  • Provide a copy of your DMV registration.
  • Not participating in net metering Schedule 135 or Subscriber Solar programs.
    • Net metering customers enrolled in Schedule 135 are excluded from this program. Net metering customers enrolled in Schedule 136, or Schedule 137 are eligible. To verify your enrollment, please call 1-888-221-7070.
  • Your account meets payment/credit criteria.
  • One-year participation commitment.
  • All of your energy use for your home will be subject to time-varying rates – not just your plug-in electric vehicle. 

Peak hours

You can save money by significantly reducing your energy use on weekdays between:

  • All months of the year: 3 p.m. to 8 p.m.
  • October through April: 8 a.m. to 10 a.m.

You'll pay lower prices on all other off-peak hours. Some holidays that fall on weekdays are also considered off-peak hours all day.


Pricing: 25.3532¢ per kilowatt-hour on-peak and 5.2004¢ per kWh off-peak

Your energy costs could be higher under the Time of Use rate. We will, however, guarantee that your energy charges won’t be more than 10% higher than they would have been on standard residential rates for your first year of enrollment. This option best suits customers who can use most of their electricity during lower-cost, off-peak periods.
