Chevy Volt Home Chargers – Click above for high-res image gallery

Want to know exactly how much it'll cost you in electricity bills to power your new plug-in car? If you live in the Detroit area and get your energy from DTE Energy, the information is in your hands The Michigan Public Service Commission announced this week that it has approved the state's first experimental rate for residential customers to recharge their electric vehicles. How much will it cost? Depends.

DTE will offer two rates, a low, off-peak rate to charge plug-in vehicles overnight or a monthly flat rate of $40 per vehicle (how will they identify a single vehicle, though?). Also, DTE will pay up to $2,500 for customers to get a "separately metered circuit with a charging station" installed or just pay for a station's installation. MPSC approved the rate to let DTE see how plug-in vehicles will impact its grid. The experimental rate goes through the end of 2012 and will be available to the first 2,500 customers who sign up.

Getting Ready for Plug-in Electric Vehicles in Michigan, MPSC Approves Experimental Electric Vehicle Rate for Detroit Edison Company - the First in the State

August 10, 2010

The Michigan Public Service Commission (MPSC) today approved an experimental electric vehicle tariff (rate) for The Detroit Edison Company, making it the first utility in Michigan to offer specific rates for electric vehicles for residential customers.

"As manufacturers begin to sell plug-in electric vehicles, it is important that Michigan's electric utilities be ready as well," said MPSC Chairman Orjiakor Isiogu. "The program approved today will help Detroit Edison evaluate the effect of electric vehicles on its electric system, offers off-peak rates that customers can use to charge vehicles, and offers the infrastructure required to charge these vehicles."

In its application, Detroit Edison proposed to make this experimental electric tariff available on an optional basis to a maximum of 2,500 residential customers seeking separately-metered service for the sole purpose of charging licensed electric vehicles.

Most customers enrolled for service under this tariff will receive a separate meter that is capable of recording the energy used to charge the electric vehicles and the time of day that the charging occurs. Eligible customers will be provided two rate options: one that provides a lower rate for charging during off-peak hours (hours other than between 9 a.m. and 11 p.m. Monday through Friday) and another that provides for a monthly flat fee of $40 per vehicle.

The utility's experimental tariff will run through Dec. 31, 2012. Detroit Edison will, at the customer's option, fund up to $2,500 for the separately metered circuit including the approved charging station; or if the approved charging station is provided by the manufacturer, Detroit Edison will fund up to $2,500 for the separately metered circuit and the installation of the charging station. Customers who opt for this equipment will be required to execute an agreement with the company that specifies terms and conditions regarding the use of such equipment.

The tariff is approved for service rendered on and after Aug. 11.

The MPSC is an agency within the Department of Energy, Labor & Economic Growth

      Here is the market for electric cars...there wont be many of these recharging station needed if these results from Spain are in order. Check these numbers....and GM will weep and rename the Volt...to Edsel.

      Difficult to analyze this. $480/year . . . well, that is probably good if you have a Nissan Leaf but not so good if you have a GM Volt.

      The "a low, off-peak rate to charge plug-in vehicles overnight" is probably the better deal though.
        • 5 Years Ago
        The Leaf has a 24 KWh capacity battery. Lets assume you use it fully every day and charge it completely every night.

        Our utility (Oregon) charges about $.10 per KWh. That's $2.40 per full 24 KWh charge. If you did that every day, it would cost $72 a month, and $864 a year.

        Reality will be quite a bit less. The above does not account for the controller's programming not to let the state of charge drop too low (usually 25%, give or take), nor does it take into account actual driving miles.

        If you assume 15,000 miles driven annually, at ~200 Wh/mile, that's 3,000 KWh, or $300.

        Oops. Didn't see everyone else doing the same math further down... Sorry!
      • 5 Years Ago
      Is this a subsidized cheaper rate? why should they charge a different amount from every other electric appliance in the home?
        • 5 Years Ago
        Why would they want to charge a different rate? Well, thats simple. Because they are trying to charge you more for it. That $40 flat rate is not a good deal at all.
      • 5 Years Ago
      I think this was probably pushed through as a research project to see what the actual impact is.
      After all - the car has a given range but people have their own given ranges they travel.
      So - I guess the unknown is basically what the average daily range of the average leaf buyer is going to be.
      And so - what impact it will have on the gird.

      However... I think the *real* thinking behind it is to get a foot in the door on the idea of separate rates for cars (for what reason !!!?!??!?!?) and what people will be foolish enough to pay over and above what they pay to toast bread.

      In essence - the thinking goes "so this is the new fuel - well then I guess we will be able to gouge on it."

      I wonder how long before a municipality thinks up a utility tax if I install my own solar panels.
        • 5 Years Ago
        Yup. Makes you wonder, doesn't it? These huge companies (utilities are included in that category) have had it so good for over a decade, no regulations, nobody looking out for the consumer, they are just used to taking every opportunity to gouge the working men and women of our country. A little price increase there, a small fee there, a reduction in product size here, it's all a big shell game.

        Scammers know nothing but how to scam. Jail time and asset seizure seems like the only answer to stop their greed.

      Detroit Metro DTE users pay .0835 per kWh. $40 a month / .0835 = 479 kWh. The average commute in Detroit is 20 miles.
      Just off the top, I would say at $40 a month flat fee DTE wins. But, the guys buying the Volt at $40,000 are buying for status, not cost save.

      Simple, I just wont say I have an EV. Or are the Police going to persecute people for using the power they are paying for?
        • 5 Years Ago
        The police will stick with prosecuting for power miss-application and leave the persecuting to the conservatives.
        • 5 Years Ago
        That would probably end up costing you even more.
      • 5 Years Ago
      i like it your cheep rate, you can find more cheep rate visit http://www.gari.pk avail all function Vehicle, i hope you like it.

      Lets see, the Leaf has a 24 kW-hr batter and can travel 100 miles on a charge, or simply 100/12 miles/kW-hr. on average. The average American drives about 12000 miles per year or 1000 miles per month (33 miles/day). The average price for electricity in America is $0.10 per kW-hr. So:

      1000 miles/month * (100 miles/24 kW-hr)^-1 * ($.10 / kW-hr)
      = $24 per month

      Sounds like a deal to me.
        • 5 Years Ago
        Just for fun, lets say you deplete the battery completely every day.

        100 miles/day * 31 days/month * (100 miles/24 kW-hr)^-1 * ($.10 / kW-hr)
        =$74 /month

        So, that would be a good deal. How much for break even?

        $40/month * (31 days/month)^-1 * (100 miles/24 kW-hr) * ($.10 /kW-hr)^-1
        =53 miles/day

        So, it *could* be a good deal if you happen to have a pretty long commute everyday.

        (That is to say that even if you are driving average distances each month, the $40/month rip-off is still cheaper than driving a gasoline car.)

      So, their giving you an off peak rate,
      and a rate structure that you could use to charge any-time-of-the-day.
      Looks like a plan for a high usage electric customer: Electric Delivery Service, charge while you load the next delivery?
      • 5 Years Ago
      I'm really not understanding this.
      What is the program supposed to teach them?
      And what has it to do with rates separate from normal rates?
      • 5 Years Ago
      I really don't get what they are trying to "learn" here, other than what people are willing to pay. I have had my Ford Ranger EV for 3 years now, and not one peep from my utility for the "additional load" of the truck. I would say if you are a homeowner, this is total BS. If you operate a fleet (or gaggle) of EVs, then the flat rate might be a worthwhile proposition. As previously demonstrated, you have to drive a LOT in a n EV to justify the $40 a month. However, the $2500 would pay for the Nissan charger that you have to install. Just weird that this is in Detroit, where I would think the emphasis would be on the Volt, which in reality doesn't need a separate charge line.

      It sounds little bit like selling unlimited text messaging for $10 a month or paying 10 cents per message, there's a breakeven point in there somewhere. Who's going to get there, and who's gonig to notice that they are spending more than they need to?

      I don't think this is about the cost of the utility, it sounds more like a structure to be able to assess tax in lieu of paying the fuel taxes that are wraped up in the price of gas. I think that paying this upfront would be more palateble than a year end tax on milage or a widespread conversion to toll roads.
