The road to finding the right rate starts with our easy-to-use electric vehicle (EV) Rate Assistant tool. Taking your home, family size, schedule, and lifestyle into account, it shows you how charging at home will affect your bill and helps determine a rate that is right for you. You can also see how electric fueling stacks up against filling the tank with gasoline.
As most residential customers, you are probably on the Residential Plan (Schedule D). Under this plan, as more electricity is used within any billing period, the cost per kilowatt hour increases. You can charge an electric vehicle on this plan, but as an EV owner, you have other options to consider.
The Residential Time-of-Use Plan (TOU-D) offers the lowest rates every day from 10 p.m. to 8 a.m. If you usually drive less than 40 miles a day (like most US drivers) and plug in every night, the plan provides sufficient time to recharge your EV at a very attractive rate, whether you use a standard outlet (120 volts) or a Level 2 charging station (240 volts).
On the Electric Vehicle Plan (TOU-EV-1), electricity used to charge your electric vehicle is billed through a separate meter at a different rate than electricity used by the rest of your home. Lower rates apply during off-peak hours of 9 p.m. to noon. Rates change seasonally, and are higher in summer
If you choose the Residential Time-Of-Use Plan or the Electric Vehicle Plan, plugging in during Off-Peak and Super Off-Peak hours can make a big difference on your bill. These plans have been designed for EV owners to charge when electricity prices are lowest, usually overnight. Even if you decide to remain on the Residential Plan, charging at night is always a good idea. It won’t generate savings, but it’s better for the grid and the environment.
Before you’re ready to start fueling your EV in your garage or driveway, you’ll want to get plugged into the different options available. Be sure to take into account your EV type, installation costs, and your driving habits.
