I have a unique setup in that when I added my Costpoint Charger to my garage, I didn’t have enough capacity on my existing electricity service, so I had to upgrade my electricity capacity. It turns out the power pole was right next to my garage, and the power company allowed me to put in a second service in my garage. The only thing on my second service is the Mach-E Charger. Hence, when I get the bill from Commonwealth Edison (ComEd), I know exactly how much it has cost me to run my Mach-E.
ComEd in Illinois allows you to pick how you want to pay for your power, so in July I switched to a variable pricing plan, which allows me to pay lower rates in the late evening/early morning hours. I have created a spreadsheet to track my miles, costs, power usage, temperature, miles per kWh, etc. and have uploaded it to the forum. For the true data geek, there is a lot of good data in the attached file. Some of the data has come from the Mach-E app, and some from ComEd . What makes the data particularly useful is that I have essentially only charged in my garage. I do mostly local driving, which, given I live in a Chicago suburb is a mix of highway and local streets. My driving is mostly in Whisper or Engage mode, and my Mach-E is a regular GT 2022.
The variable pricing for the power is pretty cheap at night. In the summer, I am running around 4-6 cents a kWh. Interestingly the delivery charges and taxes are more expensive than the actual power; delivery and taxes are running about 8 cents a kWh for a combined cost of 13 cents a kWh.
If you divide that number by the total driven, I am getting around 5 cents a mile. Looking at it another way, I have driven just over 3,000 miles for a total cost of $152.48 or, again, roughly 5 cents a mile.
A couple of things worth noting. The Ford app says that I have used 1,032 kWh, while COMED has me at 1,179 kWh. Not sure why there is so much difference. I trust the Mach-E numbers as there are some random power draws in the ComEd numbers, and I know I am not charging at those times. I have driven just over 3,000 miles during the period for an average of just under 3 miles per kWh. I did notice that I was getting well over 3 miles per kWh in the summer, and as the temps have dropped, my efficiency has dropped as well. In the spreadsheet, I show the average temp for the day, and you can see that once the temps hit the 50s, the efficiency dropped a lot.
I am curious to see what happens to my efficiency when the real Chicago winter hits. Would love to hear how this compares with other's experiences
