    If Tracksyde's Kill-A-Watt shows 3.28 kWh for a Full Charge, what is the added cost to your Electric Bill?

    If I use my Electric bill in Rochester, NY and add 10 kWh, it adds $1.25 for Supply, Delivery and tax.

    So if 10 added kWh = $1.25, or $0.125/kWh,
    then 3.28 kWh will cost me 41 cents per Full Charge.

    If a $3.85 Gallon of Gas can get my 2007 Prius 44 miles
    and if I need 4 charges to go 44 miles, if 11 EV miles per charge,
    then I'll only spend $1.64. Thanks Great.

    If I get 14 EV miles per charge, I'll only spend $1.29. Even Better

    We have tiered rates here, so up to baseline it's currently $0.14/kWh (about $0.152 including taxes), with three tiers above that that go all the way up to $0.33/kWh if you use more than 2x your baseline.

    My baseline is 10.1 kWh per day in the winter and 9.6 in the summer. This is determined by your location, whether your home is all electric or if you have natural gas for heat/hot water. I am "coastal" so I get the lower baseline - good thing I don't have a/c.

    I generally am around 210 kWh for the month, so I'll need to be a little careful to stay under baseline to get the most bang for my kWh buck.

    If we charge once at home per day (3.28 kWh), that's 98.4 kWh added per month.

    Yep, so with a baseline of around 300/mo, it will be close. I guess a few kWh at $0.17 won't matter so much. (The TOU rates for EV would only help out if I hit the 3rd tier every month.)

    Ain't EV grand.. .125 is a little above the us average. My raw off peak power is .05 and with taxes, green fees (wind) and such it works out to just over .061 /kWr, or about half your costs. Check my sig for my cost per mile..

    Dr,

    In a private message can you send me your January Electric Bill.
    I'd like to compare it to mine.

    Thanks.

    Those who live in areas w/ripoff rates would fall over if they saw 2011 Rates or these more expensive rates: http://www.seattle.gov/light/accounts/rates/ac5_erps22.htm#rsc

    From what I understand about demand charges on PG&E (they don't exist for residential but do for certain commercial schedules), you'd only get hit w/that if you hit peak draws of 30 or 50 kW at a time, under schedule 1.

    I pay $0.1506 / kWh here in NH, so a PiP charge would be just under 50 cents. No Tiered rates here.

    The Electric Membership Corp in suburban Atlanta is about $0.10906/kwh including taxes, fees etc.

    I think the rates go up in the summer another 0.02/kwh over 900 for the month.

    no plans for tiered rates or EV/PHV rates.

    The majority of my usage is off-peak (not super-off, which is when I'd charge the car). If I went to TOU-2, I'd pay MORE for all usage other than the super-off, which I would pay about the same for. So no reason for me to switch, unless my consumption jumps drastically.

    I'm in So Cal Edison territory, but I found the same thing as Sandie did, which is that it doesn't make much sense for me to switch plans at this point. Installing a separate meter, and all that goes with it construction-wise, doesn't pencil out as cost-effective. And combining their EV rate with my regular usage would have a drastic effect when it comes to "On-Peak" (daytime) usage in the summer, at 55 cents per kWH for air conditioning, etc. when being bounced up to Tier 2 rates. Even the SCE rep I spoke with on the phone agreed that, in my case, sticking with residential rates would work out best for me.

    We're on P&E. Our baseline amount is 290Kwh. We always go over. Last month's bill was 1049Kwh. It's a tiered system that starts out at $0.12845 and goes up to $0.33518. Ouch. The bill ends up averaging between 25 & 27 cents a Kwh. So, to charge my car at home, it'll be about 80 to 90 cents. We are in the process of putting up a gried-tied PV system on the roof. That will help lower the bill, and we'll be going to TOU metering which should also help a lot, especially since I'll set the PiP to charge in the middle of the night.

    Are you a Grower for California Medical ???

    LOL

    Butting in here - it's actually about average for residential use, even a little below (I'm in the industry) - that always has surprised me (and my coworkers are shocked when they hear that I use so little, relatively).

    Electric hot water, electric cooktop and ovens, electric cloths dryer way to much decor lighting ect It adds up. My house is old(ww1) and now all electric including the heat. ($.07 kwh) OK show of dirty hands and faces of everyone who has stoked a coal furnace.

    Thinking through this for a second, since I'm also with PG&E and probably have the same higher rates... if I pay about $1.00 per fill, then it's close to making sense, but not for much more. Figure that if one gets 12 miles EV, which is about .24 of the 50mpg HV expectation, then at $4.40/gallon of gas (which it is around here right now) you're saving .24 * $4.40 or $1.056. Spend more than that and you're losing money. Now, of course there are other reasons to use EV of course... but that seems like the economic break-point to me. Agree?

    (Remember, I got this thing for the HOV stickers. LOVE getting 88-96 MPG on my 30 mile commute each way b/c I can charge at work too, but might think twice about using EV if gas drops a lot (fat chance) and electricity goes up a lot more (which is much more likely)).

    Heh. No.

    There's four of us living here, 1 small server, lots of laptops, 4 decent sized TVs, ceiling fans, lights, fridge, and a hot tub, etc. Thankfully the dryer, stove and oven are all gas. When the hottub isn't turned on, our usage drops by at least 200Kwh a month. Sadly our usage is pretty typical for the area. I've replaced as many lights with CFLs and LED as I can. We replaced the old electric dryer with a gas one about two years ago. Electric bill dropped a whole bunch. Gas bill only went up a small amount.

    You would be correct there. Bunch of laptops, too.
