Consult your vehicle manufacturer on the requirements for the car. The costs for charging your new vehicle will be included in your regular monthly utility bill – just like a new appliance. UI will not need to do anything differently before you can enjoy your PEV.

To have a lower rate during off-peak charging consider switching your home to a Time of Use rate. Contact UI for more information or see our Pricing section.


It varies by car, manufacturer and the type of charger used. For example:

  • A Level 1 charger provides charging through a standard 120V outlet. This type of charging may typically provide about 4 miles per hour of charge.
  • A Level 2 charger provides charging through a standard 240V outlet. This type of charging may typically provide about 25 miles per hour of charge.

Consult the auto and/ or charger manufacturer for more information.

Before purchasing a PEV, research where you can charge it. Contact your property management.
