Does Your Utility Offer Electric Car Rates? Only 6 Percent Do

Compared with gasoline cars, electric cars are cheap to refuel, especially when charged at night using specialist electric car rates.

Designed to encourage the charging of electric vehicles at night time when grid demand is naturally lower, electric car rates are substantially cheaper per kilowatt-hour than normal day rates, incentivizing electric car owners to charge at night time. 

But according to the second annual United States Smart Grid: Utility Electric Vehicle Tariffs (Volume II) study published today by research firm Northeast Group, only six percent of all utilities in the U.S. offer special rates to electric car owners. 

When the study was compiled at the end of June, only 22 utility companies across the U.S. had launched specialist energy products for electric car owners. 

Interestingly, while California and the Pacific Northwest are considered among the states where electric cars are the most popular, Hawaii, Michigan and Nevada are the states with the most electric-car friendly utility companies. 

In those three states, 90 percent of all customers are able to choose an electric car charging rate should they so wish.

With 80 percent of all customers having access to an electric car charging plan, California and Georgia come next, despite utilities in California being among the first to offer electric car price plans. 

For the rest of the U.S. however, access to specialist electric car electricity rates is much more restricted, with only 6 percent of utilities nationwide offering cheaper electricity rates to electric car owners. 

Depending on the utility company, the way electric car charging rates are metered varies from place to place. 

In some instances, the utility company will install a dedicated electric-car electricity meter, only offering discounted or fixed-fee electricity for the charging of an electric car. 

In other cases, utility companies offer lower than usual night-time rates to customers with an electric car registered in their name, allowing the electric car owner to use the cheaper rate electricity for everything from charging their car to running their washing machine at night.

Despite what seems like a low overall availability of specialist electric car charging rates, the report points out that year on year, many more utilities offer electric car rates than did last year. 

Do you charge your electric car using a special time-of-use or electric car rate from your utility company? 

How much do you pay per kilowatt-hour, and how much money has it saved you over standard electricity rates?

  1. I live in Michigan, but haven't heard of this except for the big Michigan cities like Detroit, Ann Arbor, Grand Rapids and Kalamazoo. This is worth investigating. I'll try to let you know what I find out.

  2. Ben, I live in Michigan and have some knowledge that may be of help to you. DTE offers special EV charging rates and has two packages. Basically $.18195/kWh for peak times and down to $.07695 for off-peak. You can set your charging times to charge only at off-peak hours.

    I actually pay an even lower rate (I have a Volt) by also belonging to a SmartCurrents program at DTE. They installed an electricity-monitoring device to better understand current usage requirements and future needs and I get cheaper rates for them to get access. I live in Novi (Detroit suburb, for others), so it may not be available to everyone, but probably worth a call to DTE to ask.

    Since DTE isn't only the big cities, it's worth a try. Search DTE + EV rates.

  3. I'm in the west side of the state under the Consumer's Power jurisdiction rather than DTE. DTE IS doing a lot of great things. Consumer's may be, but they are definitely keeping it secret. Our other choices are through the big cities on the cutting edge like Ann Arbor.

  4. Ben, is it Consumers Power or Consumers Energy? For the latter, I see EV rates reduced at the following link on the web site:

    I'm sorry if there's also a Consumers Power and this doesn't help but even when I searched for Consumers Power, the search took me to Consumers Energy. Possibly a recent name change? I'm actually from Traverse City myself, but haven't lived on that side of the state for a long time... Let me know if this helps!

  5. In Ontario, Canada Time-of-Use rates have been in place for some time. My "all-in" rates are: Off Peak: 12.2 cents, Mid Peak: 16.3 cents and On Peak: 18.3 cents (all per kWh).

    Off Peak runs from 7:00 pm to 7:00 am weekdays and all day weekends and holidays.

    I plan to charge my Tesla Model S (when I get it!) at night.

  6. Kentucky Utilities along with LG&E has an LEV tariff in Kentucky, and I'm blogging about it at We had the TOD meter installed about three weeks ago. The Off peak rate is about 5 cents a kWh, On peak is just over 13 cents. There is also an Intermediate rate of about 7 cents a kWh. Weekends are all off peak. Our standard rate was about 7 cents a kWh. Lots of details about the LEV tariff at our Wordpress Blog.

  7. Well, California Utilities "might" offer electric car chargin plan, but you need to "study" it carefully and you will see it is NOT actually an EV friendly plan. For Northern California, PG&E is the main service provide and it is ALMOST a completely scam to get on PG&E's EV plan. Here is why:

    1. PG&E only allows you to switch plans once a year. So, if you get on the EV plan, but you decided to change back for varous reason, you will be stuck for 12 months.

    2. PG&E currently offers two "EV plans". E9-A and E9-B.
    E9-A is timing vary rate that allow you to use electricity as cheap as $0.037/KWh during the summer and as cheap as $0.0468/KWh. Sounds great, right? Well, look deeper... Those are off peak rate for Tier 1 usage.

  8. Continued,

    Tier 1 is the baseline rate. So, it is almost impossible to stay under Tier 3 for most Bay Area resident who actually have a family and own a "normal" home without solar. Under E9-A, the peak rate for Tier-1 starts at $0.31/KWhr and goes up to $0.50/KWh for Tier-3 and $0.544/KWhr for Tier-4 at Peak time. Sure, you will save money for EV charging, but the extra demand will push all your typical household usage into Tier 3 to Tier 4. So, your total monthly cost will go up significantly. The "peak time" usage is between 2pm-9pm. Hard to avoid for anybody. The tier 1 baseline is about 9KWh/day. So, if you charge a Leaf or Volt or a Focus EV, you will easily use up to 12-16KWh per day for charging if commute 40-50 miles daily

  9. Continued,

    Now let us talk about E9-B. E9-B is great that it will seperate the usage for EV charging by installing a seperate Meter so your baseline is lower and your normal household usage is NOT affect by the EV charging. And you can actually take advantage of the off peak charging. But here is the gotcha. A seperate meter will cost you $280 from PG&E. Then about $5K in various installation and connection fee.

    For $9k to $10k, you can get a 3KW solar leasing program installed. It is almost silly NOT to do it. I have decided to stay on the flat rate E-1 plan and charge whenever I want. (about $0.25/KWh average over Tier 1-Tier 4).

    It looks like they don't really want EVs or really want people to install solar...

  10. Since most charging Level 2 at home comes off a dedicated 240 circuit, why don't they allow this circuit to come from the main panel directly to a separate meter and then to the charger? They could easily subtract hourly usage that the EV meter uses from the other home use for billing purposes. Installation would be in the under $300 range for this type of set up.
