SRP Electric Vehicle Price Plan™

The EV Price Plan offers the most opportunity for EV drivers to save. It is a time-of-use price plan that provides customers with an opportunity to save money by charging during super off-peak times (between 11 p.m. and 5 a.m.).

    How it works

    With the EV Price Plan, you can save money when you limit how much energy you use during on-peak hours. In fact, customers on the EV Price Plan save 8.6% annually on average compared to customers on the Basic Price Plan.*

    You’ll enjoy significantly lower pricing during off-peak hours, including weekends and six observed holidays Open tooltip to learn more..

    Charge your car during super off-peak hours, from 11 p.m. to 5 a.m., for even greater savings.

    It’s 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 to 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 expensive to produce.)


    Energy is priced per kilowatt-hour (kWh) and the price varies based on whether electricity is used during on- or off-peak hours. Your monthly energy charge reflects how much energy you’ve used during your billing cycle and at what time.

    How is this plan different from other time-of-day plans like SRP EZ-3 Price Plan™?

    The biggest difference is that the EV Price Plan includes super off-peak hours, which are windows of time when EV owners can save by charging their vehicle overnight.
