I clicked on their link to send an email to their PEV (Plug In Vehicle) group. My questions were about my solar Net Metering Agreement (I currently make more kWh than I use, and I expect to use at least 2500 kWh more than I make once I'm charging an EV), whether I should consider a TOU rate plan for charging an EV and if such a rate plan is compatible with a Net Metering Agreement, and the cost for a second meter for an EV TOU rate plan.
Here is what I received back:
Thank you for visiting Southern California Edison's website.
SCE customers who have a solar generating system are eligible to enroll in the same PEV rates as customers who do not have solar generating systems.
Depending on how you use electricity, there could be significant differences among rate options. SCE customers who purchase a plug-in electric vehicle can sign up for one of the following three choices:
· SCE's standard residential rate. Under the standard residential rate plan, the price per kilowatt-hour is tiered and increases as the amount of energy usage over your baseline allocation increases. Unless you have specifically selected a different rate option, you are probably on SCE?s standard residential rate. Remaining on this rate is the simplest choice, but it may not be the cost-effective choice for some plug-in electric vehicle owners depending on how you use electricity.
· Whole-house 'time of use' rate. This rate option uses a tiered structure similar to the standard residential rate, but provides lower electricity rates at night, when many plug-in electric vehicle owners are likely to charge their vehicles. This rate may be ideal for customers who have low usage during peak daytime hours of 10 a.m. to 6 p.m.
· Electric-vehicle-only 'time of use' rate. This rate uses a second meter to measure the electricity you use to charge your vehicle, so that it can be billed at a separate rate from the rest of your home. Rates are discounted for charging that occurs during ?off peak? night-time hours. This option potentially gives customers the lowest rates for electric vehicle charging, but also involves more initial set-up cost and time.
SCE is in the process of developing a 'rate calculator' to help purchasers of plug-in electric vehicles compare their rate options.
While all customers are eligible for these PEV rates, SCE customers who produce their own power are eligible for a special metering and billing option called Net Energy Metering (NEM). The NEM schedule allows solar customers to receive a credit for the surplus electricity they supply to the grid. This credit is then applied to customers' bills to offset all or part of the 'Energy' portion of their electric bill.

So, not much new here beyond what is on their web site, except that I now know that I can have a TOU plan within a NEM schedule. I'll probably call their info line after my July 1 Nissan AV electrician visit.
