Currently, residential customers who charge their electric vehicles at home have the option of taking service on one of PG&E’s tiered residential rates or on a special time-of-use rate specifically designed for customers with PEVs. (To review these rate structures in more detail, please refer to our tariffs).
When choosing the best rate option for your charging needs, you will need to consider how much energy you typically use, how often you plan to charge your PEV and what time of day you will charge it.
Residential Rate for Low Emission Vehicle Customers
Residential customers who charge their electric vehicles at home can obtain service on PG&E’s special time-of-use rate called E-9 specifically designed for customers with PEVs. This special rate has two service options: E-9A and E-9B.
Customers can request only one E-9 rate – either E-9A or E-9B – for their residence and can only change their rate plan once every twelve months.
Update: By late summer of 2013, the E-9 rate will be closed and replaced with a new electric vehicle rate, Schedule EV, which contains these same two options. The difference is that this new rate will not have a “tiered” structure like the current E-9 rate schedule. When Schedule EV becomes available, customers taking service on either option of the E-9 schedule may choose to stay on that rate schedule, or move to the new EV rate schedule. If no choice is made, they will remain on the E-9 rate until at least the end of 2014*, at which point they will transition to the new EV rate. Alternatively, they may also choose another applicable rate schedule if so desired.
* Exact date is dependent on actions being taken by the California Public Utilities Commission.
Rate E-9A is for customers that do not have a separately metered electric vehicle charging station.
This option provides a single meter; one baseline amount is shared by both the home and PEV. If PEV charging will not significantly increase daily energy use or current energy use is mostly during non-peak hours, this may be the better rate option.
Rate E-9B is for customers with a separately metered electric vehicle charging station.
This option provides two meters: one for the home, which remains on the current residential rate (E-1, E-6 or E-7), and a second meter for the PEV on the E-9B rate. Therefore, the customer has two baselines. If PEV charging significantly impacts your daily energy usage or current energy use is mostly during peak hours, this may be the better rate option.
This option requires a second electrical panel and customers also will incur a $250 fee for the second meter. Although the E-9B rate option generally produces a lower monthly electric bill because of the second baseline for your PEV, the monthly savings may not justify the upfront costs of having an electrician install the second electrical panel.
General Residential Rates
E-1: This option provides a single meter and is a flat rate. This means that energy costs are the same during all hours. The E-1 rates are higher than the E-9 rates except during peak hours. Peak hours on the E-9 rate are only during the summer schedule (May 1 – October 31), Monday – Friday from 2 p.m. – 9 p.m.
E-6: This option provides a single meter and is a time-of-use rate. This rate is similar to the E-9A rate. The E-6 rates are higher across all time-of-use periods and the hours for peak, partial peak and off-peak are different. This rate option may be more ideal for solar customers who prefer the Time-of-Use periods.
E-7: This option is no longer available for customers; however, existing customers on E-7 may elect to stay on E-7. The E-7 rate is generally more ideal than the E-9 rates for solar customers.
