The first wave of owners are going to be blazing the trail. Hopefully once a critical mass is reached, the utilities will take more reasonable steps to accomodate. It will serve them well to make off-peak charging as attractive and as hassle-free as possible. The same applies at the legislative level. Off-peak charing is important for maximizing the benefit of the new technology in terms of existing infrastructure. It would be folly to have TOU be so unattractive that we start experiencing capacity problems early into the wide adoption of EVs.
Juiced said:Last year we had a Southern California Edison TOU (time of use) meter installed to service our MINI E. This worked great because we were maxed out on the existing house meter capacity. The TOU meter piggy backs on the existing meter and takes power from the grid BEFORE the existing main panel. You get an additional 40 amp service without a major panel upgrade. A 40 amp disconnect is required by code near the TOU meter along with a second one near the charging unit if it is more than a certain distance away. SCE off-peak charging hours are 9:00pm to 12:00 noon

mwalsh said:Did we talk about this already....does the EVSE credit carry over or is it a one-time deal like the EV credit?
If I get my car this year AND my EVSE, I would be much better off putting as much of the EVSE installation (in terms of panel upgrades and such) on my PV system install, since the credit for it does carry over!
Boomer23 said:I hope this is on topic. I didn't want to start a new thread, but wanted to remind everyone about the AMT limitation. I realize that there has been some discussion of this along with discussion of the $7500 vehicle credit, which is handled differently.
It appears to me that the Federal 50% EVSE tax credit is eliminated completely if you owe even $1 of Alternative Minimum Tax.
From my amateur reading of IRS form 8911 on Nissan's site: http://www.nissanusa.com/ev/media/pdf/incentives/nissan-leaf-incentive-56.pdf line 22 reads that if you subtract the Tentative Minimum Tax from the Regular Tax and the result is zero or less, "stop here, do not file this form" unless you are filing as a business.
To me, that means "sorry, you don't get ANY of this credit if your tentative minimum tax equals or exceeds your regular tax".
I paid about $1,000 of AMT in 2009 and I'll probably pay some in 2010, so I'm assuming that I'm s**t out of luck for this credit. That's important for me to know as I evaluate the AV quote for the EVSE install that I expect in a few days. I ran into a similar limitation for the 2007 tax year, when I installed solar PV and bought a Prius. I didn't pay AMT in that year, but my $2,000 federal solar PV credit eliminated my ability to take the $750 hybrid car credit because of the affect of subtracting the $2,000 credit and how that affected the tentative minimum tax calculation.
AMT often affects certain taxpayers in high tax states like California, where you are pushed into the AMT by deducting the high state income taxes. So yes, we in CA are in the early roll out markets, but there are drawbacks.
Your panel looks exactly like mine (minus the dual meter) - mines about 36 years old.soareyes said:My main panel is only 100 amp and 40 years old.
Too bad, but the Leaf will be much cheaper.soareyes said:This was for the Mini E I drove for the last year, now gone.
[/quote]So was this the TOU-EV rate schedule? It sounds pretty good to me, and would help me avoid any issues with my panel, which I'm still a little wary of until the AV guy says it's workable.
So did that put your house on TOU too, or can it stay on the Domestic rate schedule?
Cool. Thanks for posting that. So ... you could ask ClipperCreek to swap the orange cable to a J1772 version, and that should work for the LEAF, right ? And what is the box between the outside and the ClipperCreek EVSE ?soareyes said:For those interested, this is what the Edison's installation of the second Time of Use (TOU) meter looks like. My main panel is only 100 amp and 40 years old. The small box in the lower left contains a double 40 amp circuit breaker which connects up with a Clipper Creek box on the other side of the wall in my garage:

This was for the Mini E I drove for the last year, now gone.

Did the end of the Mini program *not* require the return of the CC ?
Hmm ... so ... like ... how often does YOUR inspector come back to YOUR house to make sure you still have that orange MiniE cable attached ?? :twisted:soareyes said:Yes, I could swap the cable to a J1772 version and it would work with the Leaf, but I was told it wouldn't be UL compliant as the box and cable are certified together as a unit. BMW had a big problem in some cities getting the EVSE installs passed by city inspectors because of this, with one driver on the east coast waiting over 6 months before passing. Some cities just had tougher inspectors than others.
Boomer23 said:soareyes and Juiced: What were the costs owed to SCE, if any, for the additional meter? Did you have an up-front cost for the meter, or a monthly fee for the second meter read, or any other charges?
Thanks. This is very helpful info.
soareyes said:Here are the TOU EV rates for Edison in my area. Off peak is from 9 pm to 12 noon 7 days a week:
Winter Off-peak 10.3¢/kWh
Winter On-peak 20.9¢/kWh
Summer Off-peak 10.3¢/kWh
Summer On-peak 28.8¢/kWh
Other than that, there are no additional charges!
