SDG&E TOU Tariffs

[russ]

I actually saw an EV here yesterday - I suppose I have missed one or two others in the past.

Without the government throwing money at them to pacify greens there is no market.

I did much better than the advertised deal, after a week of shopping. 2LT trim w/ DC Fast Charger, true $0 at signing, $134.55 / mo for 36 mo, 15k mi annually. I will also get $2500 rebate back from the state, and $500 discount on a level 2 charger, getting me a 30 A charger for ~$110, or a 16 A charger for free. This car can only charge at 3.3 kW (about 14 A), but the higher power should be useful on EV's in the future, so I'll probably go that way.

The dealership will honor the deal through end of the month tomorrow, until their inventory is gone. Less mileage would probably be $15-$30 / mo cheaper. I can PM the sales person's name and number, for anyone interested.

advertise $139/month $0 down.

I just bit on a killer lease deal for a Chevy Spark EV (good through tomorrow, while supplies last), and now I need to figure out what tariff will work best for me. With the additional consumption from the EV, I do not expect my system to achieve 100% offset, so any multiplier between generated value and consumption cost can help stretch the production I do get.

SDG&E has a bunch of plans, some just launched this year:

DR-SES
EV-TOU (applies to a separate meter for EV only)
EV-TOU-2
TOU-DR
TOU-DR-P

The TOU-DR's are new, and have a baseline credit similar to the TOU-D-A plan discussed in InsaneOctane's SCE thread. Considering how well that plan works for Solar+EV in SCE land, I want to make sure I look closely at them here too. The -P plan has an interesting feature: from 11-6 on reduce your use days, typically called in the summer or fall on the very hot days, up to 18 times per year, energy is an additional $1.16 / kWh, on top of the summertime peak rate of $0.41 / kWh.

Assuming I am a net generator on those days, (a fairly safe assumption since I don't have A/C, and I'm exporting around 3.8 kWh / kW daily during those hours right now), it seems like the credit earned on those days will pay for a *lot* of night time charging at either $0.10 / kWh, $0.13 / kWh, or $0.32 / kWh, depending on how the "baseline credit" works.

It is a long shot, but before I dive deeply into insaneoctane's spreadsheet to make it work for these plans, has anyone done any analysis already that they would like to share? insaneoctane, if you are reading this... interested in another collaboration?

How much for the Spark ?
