Assuming you charge the model 3 at home overnight, does anyone know the approx cost of a full charge? Basically what are those 499kms costing in electricity in Ontario during the overnight hours?
75 kWh (full battery capacity) will use approximately 83 kWh of electricity to charge (roughly 90% efficiency is typical).
Hydro rates vary across Ontario depending on your supplier, so check your electricity bill for details. Also, make sure you factor in the total cost of the electricity (best done over a year -- although it will be harder to separate the "overhead" from the generation costs) instead of just looking at the generation cost per kWh (which is usually what's quoted). Delivery and other charges are often separate. Most electricity suppliers in Ontario have really good data available to customers on their usage, costs, etc. I know the data I get from my supplier is quite extensive to assist you in tracking and projecting costs and usage.
Note that the Time of Use (TOU) rates typically only apply to the electricity supply cost -- other costs (such as transmission, etc.) typically do not vary by time of day (thus they are typically either per account, per month, a percentage of costs (such as taxes) or per kWh consumed). As such, it can be hard to calculate a real cost of your charges without some form of amortisation of other costs, which will be specific to your usage patterns and your supplier's terms.
I have previously calculated my projected costs, and I expect it will cost me roughly 1/4 to 1/3 of the cost of gasoline (at current prices) to "power" the Model 3 as opposed to fuelling a car similar to a Toyota Corolla (around 7 litres/100km). I am on Hydro Ottawa (which I have heard is about half the cost of Hydro One on average, but not close the almost free numbers seanxushen quotes for PowerStream).
Yes but what’s your cost per km in Ontario? How much do you drive? I’m about 2000-2500 month. I agree charging from empty is rare but I’m trying to figure the approx cost of 500kms worth of charge.You will rarely, if ever, charge from zero. I have a S90D and my monthly charging cost is between $35-$40 or just over $1.00 per day.
My original numbers were from memory from a few years back, and with a Model S I think -- probably should have redone them. And I think I used average electricity price, not the lowest tier in the TOU rates (I was doing carbon cost calculations for my whole home, etc -- so cars weren't really the focus at the time, so I just used an average rate for the electricity as I was applying it to the heating, etc.).Mine is not free either, 0.02 need plus 0.02 delivery and fees.
What’s the current gas rate 1.2? for 500km , you need 35 lite, =42$, 0.085*85=7.2$ , did I miss anything? Looks to me not 1/3,1/4 but 1/6

So $90-$150 for 2200-2500 a month?
My gas costs now are about $220
That is exactly what we pay here as well, in Owen Sound. We are on Hydro One. So basically about 1/5 or 1/6 of what we used to pay to fill up our old gas SUV, at 65 or 70 dollars a pop, which had maybe another 25 to 30 % range over the Model S. Which comes out to costing about 25% of what it cost us in gas. (I am including the assumption of about 10% inefficiency in charging).In Cobourg if I take the off peak rate (7pm to 7am) and add the distribution/regulatory cost and tax to it it works out to .137 cents per kWh. Basically .065 tou + .072 dist/reg/tax. So .137 x 60 kWh = $8.22. So about $11.50 for 500 km at 6km/kWh.
Hey sorry. I didn’t mean to ask a trick question.
Orangeville here (well,Mono)Hey sorry. I didn’t mean to ask a trick question. I was having a hard time finding straight info on what it would cost to drive the 499 kms the LR is rated for. I live in Orangeville and looking at my bill doesn’t give you the actual per kw/h charge. Off peak is 6.5 cents and the extra charges aren’t broken down. Your numbers are exactly what I’m looking for cause they include everything.

I figure that with the mileage on our Model S, we have saved at least $8500.00 but that includes about $2000.00 in “free” charging on long trips using Superchargers and destination chargers. So, in a Model 3 without the free Supercharging we would have saved about $6500.00 over the last 3 years.
Except much of the charging was at Superchargers. For instance, driving to NS the last Supercharger is in Riviére du Loup, so it is all free Supercharging until we generally stay overnight in a hotel in mid NB with a charger. So my entire trip does not cost me anything but with a Model 3 up until the NB stopover it would cost at the Superchargers. But definitely, even some of that $2000.00 would be savings in the Model 3. But even just taking the $6500.00 as a minimum, there really are considerable savings by driving a Tesla. And that is just over 3 years, putting about 72,000 km on the car. So over a longer period of time, let’s say ten years, we are talking something like $20,000.00. Which is not peanuts.Like your Model S, the Model 3 will also get free charging at destination chargers in ON, right? If so, then your $2,000 figure should still benefit the Model 3, IMO.
FWIW, I retired at the end of 2015 where I was Vice President at an Ontario electric utility in charge of Metering, Billing and Conservation Programs. So I know a little something about rate design. Where I live, my current all-in, loss adjusted, tax included rates are as follows:
Off Peak: $0.0974 / kWh
Mid Peak: $0.1289 / kWh
On Peak: $0.1702 / kWh
I am in an urban area, so anyone living in a city or town (i.e. not Hydro One rural) will be paying something very close to this.
The OP was asking how much to charge from empty to full.That is a bit of a trick question in that you actually never do that, and there is a bit more electricity use than just the usable capacity of the battery due to charging system losses. Also, I am not familiar with what the usable capacity of the Long Range battery is. If you know the usable battery capacity, add maybe 10% for charging losses and multiply by the above rates, you should get a pretty close approximation.
