    I recently received my Plug-In Electric Vehicle Rate Analysis from SCE based on my annual household usage and adding approx 2.5 hrs of charging 7 days a week.

    These are the total costs comparison with or without EV charging:

    1) Current annual household usage without EV charging on my current 5 Tier residential rate costs $1,073.13 (There are no On-Peak, Off-Peak or Super Off-Peak on this plan.)

    2) Current annual household usage with EV charging on a Two Meter Rate Option costs $1,273.15 (There are On-Peak, Off Peak and Super Off-Peak to plan your usage.)

    3) Current annual household usage with EV charging on Single Meter Rate Option costs $ 1,365.09 (There are On-Peak, Off Peak and Super Off-Peak to plan your usage.)

    4) Current annual household usage with EV charging on Current Residential Rate costs $ 1,501.91 (There are no On-Peak, Off-Peak or Super Off-Peak on this plan.)

    I just switched to the Home & Electric Vehicle Plan (TOU-D-TEV) - Single Meter and I will be saving $136.82 annually by replacing my current 5 Tier residential plan.

    The savings for a Two Meter Rate Option are much higher but the upfront costs for a separate meter, labor, etc are too expensive to justify this plan.

    I'm pretty sure I will be charging more than the 2.5 hrs I provided SCE for the analysis and my anticipated savings will be a lot more.

    Hi. I appreciate the breakdown, but can you explain more simply how much MORE money you think you'll pay per month, or per year, charging the Prius (I assume overnight, when the rates are cheapest)? I'm waiting on delivery of my plug-in this month, but when I called SCE I couldn't get a straight answer from them! They wanted me to change my plan, I think to the one you switched to, but the problem is we used the A/C way too much during the day -- live in Long Beach where it's pretty hot during the day. So, it didn't make any sense.
    I calculated, roughly, it would cost me about $1.25 to fully charge -- and this would only get me the initial 14 miles on all-electric. Doesn't seems to make good economic sense, when driving 14 miles on gas would, at $4.30 per gallon, and 50 MPG, costs me about he same!
    Is my math wrong? Thanks....

    If you are hitting the highest tier when you include the EV charging - then unfortunately yes, it's possible that gas is cheaper than electric. You may want to look into solar options to help get you down into the lower tiers.

    There is no such thing as the cheapest time to charge in a Residential 5 Tier Plan because c/kWh are based on amount used and not time.

    These are my rates:

    Tier 1 13c/kWh up to baseline allocation
    Tier 2 16c/kWh from 101% to 130% of baseline
    Tier 3 24c/kWh from 131% to 200% of baseline
    Tier 4 27c/kWh from 201% to 300% of baseline
    Tier 5 31c/kWh more than 300% of baseline

    I will be paying $428.78 more to charge 2.5 hrs/day at my current residential 5 Tier Plan.

    With my new Single Meter Rate Option, I will be paying $291.96 or a savings of $136.82

    These are the Summer rates for the Home & Electric Vehicle Plan (TOU-D-TEV) - Single Meter

    Tier 1 Tier 2**=kWh usage greater than 130% of Baseline


    On Peak 20c/kWh 55c/kWh

    Off Peak 13c/kWh 25c/kWh

    Super
    Off Peak 10c/kWh 16c/kWh


    Peak Times

    On-Peak: 10am -6pm (weekdays)

    Off-Peak: All other hours

    Super Midnight - 6AM
    Off Peak

    did they analyze your smartmeter usage? i am on PG&E and do not have a smartmeter yet but i do have a TED5000. i collected a month's worth of statistics (minus my Leaf) and wrote a perl script to analyze the usage. i would absolutely get killed on any TOU plan - $100-$150 more per month.

    unless they have analyzed your daily usage and when you actually use power, i would be very skeptical about their analysis. that 55c/kwh will really kill you.

    Thanks. You're right. I am looking at a solar option of charging a battery pack and then having that convert to A/C output. We'll see. Take care

    I'm curious to find out if you discovered any solar options with the battery?
