Making Sense of the Rates

Making Sense of the Rates

PG&E offers two electric vehicle rate plans for residential customers. EV-A combines your vehicle's electricity costs with those of your residence. EV-B involves the installation of another meter, which separates your vehicle's electricity costs from those of your home.

Both EV-A and EV-B are non-tiered, time-of-use plans, which means that the rate you pay is based on the time of day you use the electricity. Costs are lowest from 11 p.m. to 7 a.m. when demand is lowest, making this the best time to charge your vehicle. Electricity is more expensive during Peak (2-9 p.m.) and Partial-Peak (7 a.m.-2 p.m. and 9-11 p.m.) periods. See graphic below for detailed information on EV rate costs and times.

Making sense of the rates. Lowest cost, ideal charging times - off peak: 11pm - 7am. Partial-peak: 7am - 2pm and 9pm - 11pm. Peak: 2pm - 9pm.
NOTE: Weekends and holidays only include Peak (3-7 p.m.) and Off-Peak (all other hours) periods.

Make an Informed Decision
Before selecting a plan, it's a good idea to review your current energy usage data and your driving habits. You can check your energy usage by logging in to My Energy, your PG&E online account.

Check this chart to find the best plan for you.

(non-tiered, time-of-use)
Higher energy consumers (tier 3 or 4) or lower energy consumers (tier 2) who will drive often. Single meter for your home and EV charging. The price per kilowatt-hour varies depending on the time. Avoid charging during peak hours. To maximize savings, consider shifting other household energy usage to less expensive, low demand hours (see chart, above).
(non-tiered, time-of-use)
Customers who want to track their EV charging separate from their home energy consumption with a dedicated meter. Dual meters: one for your household and one for electric vehicle charging. The price for charging varies throughout the day. Your home energy use is measured separately. Costs for second meter installation may be significant. One-time $100 fee per meter, plus cost to install charging station and second electric panel. Service upgrade may also be required.
(tiered, time-of-use)
Low energy-use customers who use major appliances in the early morning or late evening hours instead of weekday afternoons. Single household meter for your home and EV. The price per kilowatt-hour is based on the time you use electricity and the amount of electricity you use. You'll need to conserve energy throughout the month, but the price you pay also varies throughout the time of day and season.
Customers with low energy usage (tier 1) who can't shift their usage to demand hours and do not drive that often. Single meter for your home and EV. Costs are based on four usage tiers. As you use more electricity during your billing period, you move into higher priced tiers. You'll need to conserve energy to stay in lower priced tiers as long as possible.


  • Your total residential consumption will vary if you charge at work or in public locations.
  • Customers can change their rate plan twice every 12 months. If they opt to install a meter dedicated to their electric vehicle, they are only eligible for EV-B on that meter. Their house, however, will be eligible for PG&E's tiered or tiered, time-of-use rate plan.
  • EV-A and EV-B customers are ineligible for the following programs: CARE, FERA, Medical Baseline, SmartRate™ and Employee Discount.
  • PG&E's experimental EV rate plan (E-9) was closed on August 1, 2013. This option is no longer available for new EV customers. However, existing E-9 customers may remain on the E-9 rate plan until it is eliminated in late March 2015, or later, through a decision in PG&E's 2014 General Rate Case Phase II proceeding. At that time, existing E-9 customers will transition to their new EV rate. Customers on the single metered E-9A rate plan may request to transition to non-EV residential rate plans.
