Just got my electric bill.....

Just got my electric bill.....

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?

That is Awsome! Congrats Hogfighter!

riceuguy | 01. maaliskuu 2013

Hogfighter, what's you electricity cost per kwh?

Hogfighter | 01. maaliskuu 2013

right at 11 cents.

fluxemag | 01. maaliskuu 2013

Awesome! Those of us with gas guzzlers and cheap electricity are really going to rack up the energy savings. My car does 19mpg premium and I drive 1250 miles per month. I estimated my electric bill will increase $35 a month and cancel out $250 a month in gas!

I used 400Wh/mi, $0.07/kWh, 1250 mi and $4/gallon to get to those conclusions.

GeekEV | 01. maaliskuu 2013

In LEAF parlance that works out to 3.6 miles/kWh. I only get ~3.2 in my LEAF, but I drive aggressively. Were you babying the S?

gabriel.dogaru | 01. maaliskuu 2013

Something is wrong here!
In this case you obtained 818/3000=0.272kWh/mile
With such a consumption and a battery of 85kWh you can reach 312miles!
This is quite much!

Hogfighter | 01. maaliskuu 2013

@Geek....I'm getting around the same as your LEAF. I did cheat once and filled up at a library (for free). I drive normally but with the occasional wild-acceleration just to make me smile, although it doesn't seem to burn any more electricity to do so.

The car likes to coast, and likes it when I'm on the highway in traffic (the drafting that ensues when in traffic helps a ton). Smooth roads also add to the efficiency more than I thought it would.

riceuguy | 01. maaliskuu 2013

My electric--on average--should be pretty close to this rate, and I also have a premium-only ICE, about 1250 mi/mo. Now, I expect to burn through a bit more electricity per mile than the OP, but I do imagine I'll save at least $150/month. Of course, even with that savings, I'll still be spending an obscene amount more per month than I do today when car payment is factored in! This is not a car you buy to save money. It's a car that saves a little money so you feel a little less guilty about just how much you're spending on it. You buy this car because it's absurdly cool and fun and because even waiting for your car to show up it makes you feel excited, special, and--let's admit it--a little bit superior (because hey, you're saving the planet while driving the coolest car ever). :-)

drp | 01. maaliskuu 2013

That's fantastic news! Just about what I expected although my electric is only eight cents per kilowatt. If you figure 245 miles for 85 kW, full charge, and then at your $.11 that would be $114 for 3000 miles. What a bargain!

drp | 01. maaliskuu 2013


How many miles do you drive a day? I will be driving about 165 daily miles four days per week and that is also going to be 3000 miles per month. That includes my other driving.

EVTripPlanner | 01. maaliskuu 2013

my spreadsheet to estimate electricity costs and savings vs. ICE at

my cost about 1/3 of ICE - SoCal Edison not quite so cheap...even with my solar.

peahl | 01. maaliskuu 2013

My cost exactly also 1/3 of ICE

Captain_Zap | 01. maaliskuu 2013

We have been putting about 1100 miles a month on the Model S and the power bill has gone up about $33 a month.

It has been a mild winter here in the Pacific NW. Only one cold spell and no extended power outages so far but it sounds like our numbers are comparable.

With my BMW's thirst and taste for premium fuel we are saving about $275 a month. (That is driving the BMW very conservatively and the Model S very indulgently.)

I still like the fringe benefits of the Model S more than anything.

lolachampcar | 01. maaliskuu 2013

MS loves Florida. I'm making rated at 70mph on I95 with the AC on! Sometimes that falls to 65mph if the wind is against me but, still, the car just loves flat warm places.

With that kind of milage, I'd be interested in how your rear tires are wearing. Do you have 21s and, if so, which tires?

Brian H | 01. maaliskuu 2013

An irony: California is the home of TM, and has more MSes than anywhere. But CA really hoses electricity buyers, minimizing the $ benefits of owning one.

drp | 01. maaliskuu 2013


Maybe that's why Tesla has focused on filling California full of free superchargers! Now it's time to spread the wealth and let the rest of us enjoy it between the two coasts.

Vern110 | 01. maaliskuu 2013

I get 0.054/kWh in Chicago, on average ~ 370 - 400 Wh/mile (in the winter). ~1500 miles per month. Average electric bill ~ 30-40$ per month, compared with my M5 ~$700-$900/month in gas (premium). Now that is savings on huge magnitude. The averages take into account, I tend to be a more aggressive driver than the norm.

GLarwill | 01. maaliskuu 2013

@BrianH. Yes, PG&E rates are nasty compared to national average. You should check out the E9-A and E9-B tariffs. You can charge a car off peak for around 4¢ per kWh. Much better than the 29¢ I currently pay for house electricity.

SD Supercharger | 01. maaliskuu 2013

Hey Brian-
Not everyone in California is getting hosed. SDG&E (San Diego) is only .08/kWh (.14 bundled) during off peak hours.

I happen to believe Hofighter's numbers. Florida is optimal for the MS. Flat and warm is the key. Don't forget, a Florida MS got 423 miles out of a single range charge.

Objective1 | 01. maaliskuu 2013

@Vern110 Saving around $700 per month will pay for a new battery pack within little more than a year at most.

From then on, 10+ years of saving $700 per month awaits you. Congrats!

akikiki | 01. maaliskuu 2013

@Hogfighter: That's wonderful. Leaves you with that internal glow that you are getting to stick it back to "the man".

Brian H | 01. maaliskuu 2013

10+ yrs at $800/month pays for the whole car!

jbunn | 01. maaliskuu 2013


I'm moving out of the northwest where we have expenisve gas ($4) and cheap power ($0.11 or less). I'm moving to CA where gas is expensive ($4), and power is crazy expensive (some places $0.30).

Most electric power in CA is generated by natural gas. Right now the stuff is dirt cheap.

Yeah, I'm kind of pissed about that. Kind of takes some of the economic advantage out of the equation.

Pungoteague_Dave | 01. maaliskuu 2013

What's an electric bill? We have a 27 kw solar panel system, almost entirely paid for by the federal government (tax credit, USDA grant for farm installation, and business expense deduction). Thank you Uncle Sam.

Our bill to be on the grid is $8.20 per month, but we get about $1,600 per quarter in SRECS, so net over $6K per year from electricity.

Captain_Zap | 01. maaliskuu 2013


At least solar is a viable option for you now!

Sorry to hear that you have to move though.

GLO | 01. maaliskuu 2013

First full months bill was $44.00 for 2,000 miles. Yeah!!

Brian H | 02. maaliskuu 2013

2.2¢/mi ain't bad! Where are you.

Hogfighter | 02. maaliskuu 2013

@DRP - I'm driving just over 100 miles/day and 85kw battery pack. No range anxiety fact, I rarely look at the mileage remaining. I charge at only 25 amps because I have a theory (quite probably incorrect) that less electricity is lost when I charge at a lower rate. Every morning it's ready to go with 240 miles of charge!

@lola - I have the Continentals and 4k miles on the car. The rear tires have a little more wear than the fronts, which are still like new. To all who don't live in South Florida, our roads have no curves. Just turns.

@Brian - absolutely right (except for the stupid maintenance cost!)

Cattledog | 02. maaliskuu 2013

Vern - $700-$900/month for gas? Say $800 and say $4/gallon for premium, that's 200 gallons and at 1,500 miles only 7.5 MPG. That would be outrageously aggressive driving even in a M5! But, you go guy!

Mark E | 02. maaliskuu 2013

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.

lolachampcar | 02. maaliskuu 2013

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.

Vern110 | 02. maaliskuu 2013

@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.

TonyF | 02. maaliskuu 2013

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.

TonyF | 02. maaliskuu 2013

BTW, it's been a cold winter in Philly and my average usage since day 1 is 408wh/mi

lolachampcar | 03. maaliskuu 2013

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.

nickjhowe | 03. maaliskuu 2013

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:

nickjhowe | 03. maaliskuu 2013

The ups/downs are going over the flyovers on the freeway.

Ron5 | 03. maaliskuu 2013

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.

stevenmaifert | 03. maaliskuu 2013

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!

nickjhowe | 03. maaliskuu 2013

@Ron - I'm averaging 346 - but still only 7 weeks into ownership so a disproportionately heavy right foot. :-)

Hogfighter | 03. maaliskuu 2013

Wow, Nick....nice!! That's an impressive number.

tommy-tesla | 03. maaliskuu 2013

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
Earnings (PG&E).

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.

DouglasR | 03. maaliskuu 2013

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.

nickjhowe | 03. maaliskuu 2013

@Hogfighter -I'm wondering if I had a bit of tail wind help.

dtesla | 03. maaliskuu 2013


$90 / $.11 per KWh = 818 KWh used

818 KW / 3000 miles = 272 Wh/mile

Sounds like about right.

cloroxbb | 03. maaliskuu 2013


did you factor in conversion loss?

mallynb | 04. maaliskuu 2013

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.

wbrown01 | 05. maaliskuu 2013

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.....

SD Supercharger | 05. maaliskuu 2013

.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.
