At Home Charging costs vs. Superchargers

[HellsKitchen]

Question for those who use both. I know there are many factors that come into play, especially location and peak/off-peak hours, but just as a broad approximation: how much less expensive is charging at home than using a super charger? Is it as much as 50% cheaper?

My home charging is 1/3 the price of Supercharging.

Home: 10.5 cents per kWh, although I'm on a very aggressive time-of-use rate plan with demand charges and I work it
Supercharging: 32 cents per kWh average

Home: roughly 3 cents per mile
Supercharging: roughly 10 cents per mile

I pay $0.065/kWh at home. I recently used a Supercharger this weekend at a rate of $0.32/kWh. For me it's about 1/5 as much to charge at home. Also, I don't have to make a special visit to a Supercharger (good thing too because the nearest one is 35 miles away).

The national average for residential electricity is apparently $0.1059/kWh. I have no hard statistics but my own experience for the past year and a half shows Supercharger prices average around $0.267/kWh. That includes the end of 2020 and all of 2021. I think prices have been slowly increasing and Big Earl's reference of 1/3 is probably a good national average.

Charging at home would be $0.11kWh if I didn't have solar; local superchargers are $0.35

I also average close to 0.10/kwh vs 0.27/kwh at local SC.

in my area, in home price is more expensive than supercharge or public L2 charging.

I also average close to 0.10/kwh vs 0.27/kwh at local SC.

I average around 0.15/kWh at home vs about 0.35/kWh in North Florida.

It's as *little* as 50% cheaper, but usually better. Often a quarter of the price or less. With home charging, you can take advantage of off peak rates as well as drop the amperage down. It's also healthier for the battery.

Are you guys adding electricity delivery charge when calculating home charging cost or just supply charge? In my opinion if we don't add delivery and monthly charge it would be inaccurate cost for home charging.

My $0.11kWh would include all charges

I’m located in Michigan and my off peak charging rate is .018/kWh. Superchargers are .28/kWh. On average I am charging 80% at home and 20% at Supercharging stations.

Yes. My 0.15 kWh is my whole bill divided by kWh consumed.

My example includes generation, distribution, taxes and all fees. Total bill $ divided by kWh used.

My home charging cost is close to $.013 / kWh all-in. I briefly looked into converting to a Time-of-Use plan, but it's not clear that would work out for me. My dominant home electricity use is not charging the Tesla, it's running the central air during the hot part of the day - and I can't shift that to nighttime. Running appliances and the HPWC at night won't make up for that on-peak use. Solar would be a natural, but a heavy up-front investment.

I believe the supercharger rate is 35 cents locally, nearly 3X my home charging cost, so I won't be using those much at all. I do still have 1000 miles from my referral program (ordered the car in 2Q 2021). These will expire in May, and I've never used any so far. I'd be happy to give them to a friend but it seems this is not possible.

I pay $30/mo for unlimited non-prime time charging. Have 2 teslas and a leaf. Makes it pretty inexpensive to charge at home.

How do you manage that?

I don't count the connection fee, because it doesn't matter how much I use it's going to be the same. All other aspects are calculated in. Turns out I don't actually pay $0.065/kWh. The real number is $0.0648627450980392/kWh.



I'm in a town with a co-op. Our utilities are wicked cheap. Unfortunately I will be moving soon and everything is going to nearly double.

Pilot utility rate plan that I lucked into. Did have to pay extra when I put in the WC to have a meter box installed. But that was in 2017 so I’ve had this 5 years now to help cover the install costs.

It depends where you live. SF Bay Area. Home charging is as expensive as supercharging.

 

[alexcue]

My home averages .22/kWh that includes all costs and pretty much year round. Luckily my boss put in a charger at office for my Old Prius Prime years ago, and now we charge about 3 cars during the day. Since I get in first I get it for free for at least 2 hours every day. So anyway, at home is about 2/3 Supercharger price, but I hardly pay any thing for normal commute.
