Electric Vehicle Price Plan

The SRP Electric Vehicle (EV) Price Plan is for customers who own or lease highway plug-in hybrid electric vehicles (PHEVs) or battery electric vehicles (BEVs.)

Though similar to the Time-of-Use (TOU) Price Plan, the EV plan offers an additional opportunity to save by charging your vehicle during lower-priced super off-peak hours every day between 11 p.m. and 5 a.m.

With the EV Price Plan, you can save money on your electric bill by limiting energy use during on-peak hours and when SRP's energy costs are higher. Enjoy low off-peak prices all other weekday hours, all weekends and on six observed holidays.1 You'll get even lower prices every day from 11 p.m. to 5 a.m. during super off-peak hours.

The Electric Vehicle price plan could be a good fit for you if:

  • You own or lease an electric vehicle.
  • You are able to perform most of your at-home vehicle charging between 11 p.m. and 5 a.m. when prices are lower.
  • You are able to use less energy in your home during higher-cost on-peak hours.
  • If you also have solar installed at your home, see if the EV Export Price Plan is right for you.
