Thanks! This is good to know. We have solar panels under net metering which produce a slight surplus. I estimated our incremental electricity billing under each rate plan and converted it to an equivalent price per gallon of gasoline to fuel my current car. The worst rate plan looks very good, but some plans are much better.
Code: Select all
Equivalent $/gal of gasoline
1 meter 2 meters
EPEV-M $1.45 $0.48
EPEV-H $0.51 $0.38
(Your mileage may vary.) These calculations are based on measurements and estimates of how much electricity we produce and consume, by month of year and by hour of day; number of miles driven per year; miles per kWh of Leaf; MPG of current car; current baseline allocation; SDG&E definitions of summer and winter, peak, off-peak, and super off-peak.
I'm not sure what rate I'd choose if I weren't in the EV Project, and the experimental rates were still possibilities. I'm glad the EV-TOU3 rate is gone, with the $13/month meter charge! I can't tell from SDG&E's rate sheet and explanatory pages whether on EV-TOU they would charge one $3.81/month meter charge for the account, or two $3.81/month meter charges, one per meter. If the latter, that would raise my "equivalent gasoline price" by $0.26 per gallon. For the EPEV-H schedule, the meter charge would make it better to have a single meter for house plus car. But for the EPEV-M schedule, it would be better to pay for the extra meter.
Again, you might get very different results if you drive more miles than I, live inland and have an air conditioner for your house, have larger or smaller solar panels than I, etc.
