Electric Vehicle Price Plan

The Electric Vehicle (EV) Price Plan works like the Time-of-Use Price Plan, but it’s designed to help EV owners save. The biggest difference is that, with this plan, customers can lower energy costs by charging their vehicle during super off-peak hours, between 11 p.m. and 5 a.m.

Customers who switch from the Basic Price Plan to the EV Price Plan save an average of 9% by using energy during off-peak hours. *

With the EV Price Plan, you can save money when you limit how much energy you use during on-peak hours. You’ll enjoy significantly lower pricing during off-peak hours, which include weekends and six observed holidays.1 (Energy is more expensive to produce during on-peak hours. That’s why SRP offers price savings to customers who can shift their energy use to off-peak hours.)

The EV price plan could be a good choice for you if:

  • You own or lease an electric vehicle. (It must be a highway plug-in hybrid electric vehicle or battery electric vehicle.)
  • You’re able charge your vehicle at home between 11 p.m. and 5 a.m.
  • You’re able to use less energy at home during on-peak hours. (During these hours, energy is more costly.)

If you also have solar installed at your home, see if the EV Export Price Plan is right for you.
