I drove 3,000 miles in my MS last month. My electric bill went up $90 (South Florida).
The car I used to drive got 13.5 mpg...that's a savings of $760, in one month. How cool is that?
Premium 98 octane unleaded is $1.50-1.60 per litre, (about $5.50-$6 per gallon) here in Sydney, Australia. Off peak electricity is 11c per kWh. I'd save around $300 per month - enough to fund just under $17,000 at 6% over 5 years.
Yes, our interest rates are also very high here.
I've got Pilots and I've lost 25% of the inside shoulder on the rears in 800 miles (they are now on the front). I'm at 1800 miles now and need to measure both front and rears across the contact patch again.
@catteldog, Chicago premium gas prices at one time came up to ~$4.90/gal. The 08' M5 mpg rating was 13/hwy, 9/city, I know crazy. Even in my 4d jeep wrangler, still paying ~ $400-500 / month with same mileage.
I have had 2 electric bills since receiving the model S. Unfortunately, this has coincided with my son graduating from college and moving back home (with all his electronics and habit of leaving every light i the house on. My electric bill premium for each month of the two months I have had the car and my son home is almost exactly $100. I am estimating that it is about $75 MS and $25 my son. The 'all in' cost of electricity is $0.14/kwh. I will keep track for many months but for now, this is what it is costing me.
BTW, it's been a cold winter in Philly and my average usage since day 1 is 408wh/mi
I'm running about 306 without test rides and 345 with test rides in Florida. I had no idea my driving style would allow for rated range. That says a lot for Tesla's marketing to actually provide the range they spec.
Drove up I-95 yesterday and on the way back did some testing on Wh/mile. At 70 mph, and 63°, I averaged 296 Wh/mile over five miles:
The ups/downs are going over the flyovers on the freeway.
Yes, I have also had great measured Wh/mi in South Florida. Over the past 9,000 miles, my total average is 319, including many test drives and higher speed commutes.
Made a round trip from San Diego to the Hawthorne Supercharger this past week. Cruise set to 65. Outside air temp 65-70 F. Climate control off. 243.3 miles driven. 244 miles of rated range consumed. Averaged 290 Wh/mi. I'm impressed!
@Ron - I'm averaging 346 - but still only 7 weeks into ownership so a disproportionately heavy right foot. :-)
Wow, Nick....nice!! That's an impressive number.
Just to add my data point: I live near San Jose and the Model S have
pushed me way into Tier 4, thus paying $0.34/kWh to Profit, Greed and
I'm saving compared to the gas I used to spend, but not that much.
Unfortunately, all the options (Solar and/or E9-B) require a
non-trivial investment with long-ish ROI - longer than I expect to
stay in the house.
The time-of-use plane E6 would be slightly better, but Schedule EV
is around the corner and _may_ be a better option. As you can only
change once every six months, I'm biting my time for now.
Outside temperature seems to have a larger effect than I previously thought. I don't get near these numbers, but I did notice that on one flat segment of my CA trip I averaged around 300 going 68 mph. The main difference from other flat segments was the temperature. I can't wait for summer.
@Hogfighter -I'm wondering if I had a bit of tail wind help.
$90 / $.11 per KWh = 818 KWh used
818 KW / 3000 miles = 272 Wh/mile
Sounds like about right.
did you factor in conversion loss?
I can't wait for our May-June delivery! I estimate that our electric bill will average $17/mo more, and our net savings will be $100/mo compared to gas for our ACURA RL.
I used to drive a VW Toureg V6, gas mileage was bad. At $4.25/gal I was putting $800/month in the tank because I drive 80 miles a day to work. My car note is $900/month for the Model S, but well you do the math. Save money and drive a that car, hell you gotta be stupid not to consider it. Folks should at least do the math.....
.34/kWh is really high. We only pay $.14 off peak in San Diego. To reduce the large upfront expenditure, have you looked into leasing solar equipment from Solar City? With prices that high it might be worth your while.
My updated electricity consumption estimator at http://EVTripPlanner/calc.php - snapshot below. Includes parasitic load while parked.
Yes, $0.34/kWh is high, but it's not unusual here
I did talk to SolarCity at length and got multiple offers from them,
but shock, none of their offers are actually a good deal! I'm very
unimpressed with their leasing offers and if you look at the cost to
buy the system outright, they are 80-100% more expensive than some
of the local offers I've seen for similar installations.
For now I'm waiting for Schedule EV while I continue to evaluate
my PV options.
The address is wrong in your post
@hsadler - thanks...afraid I can't edit!
There are options in CA to get EV charging for ~ $0.04/kWh between midnight-7am with PG&E. Look into E9-A and E9-B tariffing. Here is the Doc I'm referencing: http://www.pge.com/tariffs/tm2/pdf/ELEC_SCHEDS_E-9.pdf
Aren't both those going away soon?
Yeah my first bill was higher too - about $80 more than normal. I drive about 1,800 miles a month. The above are rough estimates, but given the size and luxury vehicle that we're driving, it still is about 1/3 of the cost of gasoline.
If you are in California, talk to Solar City. You can lease the solar panels so that your monthly electrical costs go down. There is no up front cost for the installation. I am actually saving several hundred dollars since they are going to upgrade my main panel with a bigger circuit breaker as part of the solar install. With the solar panel installed, I will be paying Solar City about $106/mo for electricity.
