There are a few interesting statements in the San Diego Union article such as:
How big a discount will depend on which of three rates they end up with. Some people will pay 13 cents a kilowatt-hour to charge at night, and 27 cents in the daytime. Others will pay 7 cents at night and 38 cents in the daytime.
Does this mean you will be assigned randomly to one of the three rate structures? If you are not generating power I do not think you would want to be in the last category with daytime rates at $.38/kWh. As another poster commented, it would be very expensive to run your AC during the day. However, this would be great if you are generating power and receiving $.38/kWh for excess generation during that period. Presently I'm in the SDGE DR-SES time-of-use rate (only for solar customers) and receive $.275/kWh for excess generation from 11AM-6PM M-F. I would like to get $.38/kWh if I could. Actually, the rate schedule that I am presently in is very close to the first rate schedule mentioned in the article. I asked SDGE and they told me that I could change to the EV rate if I purchased an EV, even as a solar customer. But the EV rate that was in place isn't as favorable for excess generating because the peak window is 12-6 PM in the summer season, one hour shorter than the DR-SES schedule. And, the lowest rate is $.137/kWh and only between 12 AM- 5 PM. In some cases the 5 hour window will not be large enough to fully charge the Leaf battery.
Electric-car owners will have two utility bills, one for the car, the other for their home. There are already 27 electric car owners in San Diego paying special rates, Larson said.[/i]
This would require two meters. SDGE (before this change), had 3 EV rates and two of them required a separate meter. One only required one meter for the EV and house combined. So I'm not sure if these three experimental rates require a separate meter.
