I pay $.06/kWh at home. When travelling, I have been charged anywhere from Free to $.87/kWh.

It Doesn't say where you live, but here in Cali, My rates are in the vicinity of $0.51 a kW (PG&E) (Gasoline is about $4.00+/- a gallon). I have solar, so I have an expensive EV Truck (Love) and a Solar system to pay for. My savior is the 68 eMPG. Folks in other parts of the nation that are paying 20% of what I pay, are the ones saving.I gotta be honest. I have yet to see any savings from owning my 2024 Lightning extended range Lariat. The first month cost me roughly $100 to charge that was the month of December. January it looks like about $200 a month to charge. Can somebody please explain where the savings are?I love the truck but wow it’s expensive to power up!
Love the theoretical math no dispute.....but the variables are variableActually, AI comes very close to what everyone, especially JvdMaat is stating in this forum thread....this is obviously based on averages. If you are paying over 30 cents per kWh, you are not saving much if any.
To determine the break-even point for miles per gallon (MPG) and miles per kilowatt-hour (kWh) for a Ford Lightning, we need to compare the cost of driving the vehicle using electricity versus gasoline. The break-even point occurs when the cost per mile for both energy sources is equal.
Step 1: Gather the necessary data
The formulas didn't paste well here so I removed them.
- Ford Lightning Efficiency: The Ford Lightning has an efficiency of around 2.0 miles per kWh (this can vary based on driving conditions, but 2.0 mi/kWh is a reasonable estimate).
- Gas Vehicle Efficiency: Let's assume a comparable gas-powered truck gets around 20 MPG (this can vary depending on the specific model and driving conditions).
- Cost of Electricity: Let's denote the cost of electricity as CeCe dollars per kWh.
- Cost of Gasoline: Let's denote the cost of gasoline as CgCg dollars per gallon.
Step 2: Calculate the cost per mile for both vehicles
Step 3: Set the cost per mile equal for both vehicles to find the break-even point
Step 4: Solve for CeCe (cost per kWh) in terms of CgCg (cost per gallon)
Step 5: Interpret the result
The break-even point occurs when the cost of electricity (CeCe) is 10% of the cost of gasoline (CgCg).
Conclusion
- Example: If gasoline costs $3.00 per gallon, the break-even cost for electricity would be:
Ce=0.1×3.00=$0.30 per kWhCe=0.1×3.00=$0.30 per kWh
The break-even point for the Ford Lightning, in terms of cost per mile, is when the cost of electricity is 10% of the cost of gasoline. For example, if gasoline costs 3.00pergallon,thebreak−evencostforelectricitywouldbe3.00pergallon,thebreak−evencostforelectricitywouldbe0.30 per kWh. If electricity costs less than this, the Ford Lightning would be cheaper to operate per mile compared to a gas-powered truck. If electricity costs more, the gas-powered truck would be cheaper to operate.
I'm from the same state, national grid customer. Yes, perhaps the cost is around 8 cents per kwh but that is NOT in including the delivery charges and fees and taxes for each kw. The actual cost per kwh out of pocket is around 21.5 cents. Sometimes it up to a tad over 22 cents per kwh... Depends on the month.So funny this came up today. I did the math yesterday since Dec 2022. Used 13734 kwh according to my emporia vue. 7.5 cents on average so $1030. 28000 miles with my old vehicle at 21 mpg is about 1330 gallons @ $3.25 is $4322, Saved $3292 in 2 years
This is why EV's pair so well with solar, particularly in MA with it's favorable Net Metering regulations. Back in the winter of 2022 (I think) when NGRID jacked their rates to $0.48/kWh i made SOOOOOO much credit in February and March that I haven't spent it back down yet.Yeah, Mass is expensive. I did the math on my wife's old 2014 F150 vs her new Lightning. At current gas prices ($3/gallon), her old truck doing 15mpg, and the Lightning doing 1.6mi/kWh.
Going off that, it cost about $0.20 per mile in gas, which is $0.32 in gas to get 1.6 miles.
And we pay $0.33 per kWh at home. So the Lightning EV is actually more expensive to charge at home than her gas vehicle was. That really caught me off guard until I saw Average energy prices for the United States, regions, census divisions, and selected metropolitan areas : Midwest Information Office : U.S. Bureau of Labor Statistics
Owning an EV is cheaper than gas everywhere except New England, California, and Hawaii (potentially depending on their gas prices.. Those are also higher)
All the places online that say EVs are cheaper to charge at home than gas never mention the caveat of the few states where electricity is more expensive or on par with gas prices.
(At the efficiencies (15mpg vs 1.6mi/kWh), electricity should be less than 10% of the cost of gas to make home charging cheaper (so if gas is $3, you need to pay less than $0.30 for electricity. If gas is $4, you can pay as much as $0.40 to break even))
Yeah, I have solar. And two years ago it covered 99% of my electricity (I had a $30 bill in March I think before solar outproduced our monthly usage again). But then we got geothermal, and now the EV.. And our December bill was $700.This is why EV's pair so well with solar, particularly in MA with it's favorable Net Metering regulations. Back in the winter of 2022 (I think) when NGRID jacked their rates to $0.48/kWh i made SOOOOOO much credit in February and March that I haven't spent it back down yet.
Also in MA and did similar math before purchasing and realized it’d be about 1:1 roughly a bit less for the EV. Hoping to get some solar (payoff on that is about 5 years) and that should offset some of the electrical costs.Love the theoretical math no dispute.....but the variables are variable
2+ years of Lariat-ER trend of consumption is 1.5 MPK over 22,000 miles
My former PSD F250 got 15 MPG
Current Electric rate is $0.3391 / kWh
Current Diesel is $3.499 / g
In present value 22,000 miles my Lightning has a hair thin advantage.
Electric $4973
Diesel $5132
Regardless of all the numerical machinations, I love my 2022 Lightning Lariat-ER
Or Virginia, on the EV plus Home billing plan, 4.8 cents (summer) to 5.79 cents (winter) per kWh between 1am and 5am.Time to move to Maine $0.11 kWh (heat pump rate, solar in the summer).
