I just passed my six-month mark for ownership of my S85 last week. It so happens that 3 days later I had opportunity to try the new superchargers at then Glen Allen, VA location during a road trip and got my first taste of 120Kw charging.
This got me to thinking about the usefulness of the superchargers, the expansion plans, and the value it provides for owners. For me, the value looks to be significant.
In the first half-year of owning my S, I've used the SC's 6 times. As mentioned, I then used on for the 7th time 3 days in to the second half of my first year. That puts me on track to use the SC's a dozen times in a year. One of the trips was a little unusual and unexpected, so I'll lower the projection to 10 times/yr on average.
In each of those cases, supercharging enabled me to take the Model S on a road trip that normally we would have taken in the family SUV, a Toyota Sequoia, which gets ~15-17MPG. Each of those trips would have required an initial fuel-up of the Sequoia's 25 gallon tank. Fuel has been near $4 around hear earlier this year, but is now about $3.25. Using $3.50 as an average, I'll avoid paying $875 this year in road-trip fuel costs. Of course, my cost to charge the S before leaving is about $8, so I'm still in excess of $800 ahead.
In each of those cases I am able able to supercharge the S along the way for free. In many of those cases I would have needed another gas stop for the SUV. Because the range of the SUV is ~400 miles, as opposed to ~265 for the S, I'll try to be conservative and say only half of the time I would need the second fuel-up. Avoiding that will me and additional $437.50.
So assuming that my experience thus far for the year hold, and my projections are at least in the ball park, I'll be ahead to the tune of $1312.50. Let's call it $1250, again to be conservative.
Now obviously, Your Mileage Will Vary... literally. If your "other ICE car" gets better mileage it could easily be well less. Ditto if you travel less. On the other hand for some folks who travel more frequently on road trips it could be significantly more. It's not unreasonable to think that supercharging enables annual savings in the $500-2000 range for a good portion of people.
In my case I'll pay for the capability in just over 18 months (assuming gas prices don't rise, in which case it will be even earlier), assuming the $2,000 it's valued at. Over the 6-yr loan duration of the car, I could be nearly $6,000 to the good. If I keep the car even longer, it's simply more money in my pocket.
In my opinion it's a no-brainer to add as an option to the 60Kwh model... and in realty makes consideration of the 85Kwh model that includes the SC option for free one to consider very closely for those on the fence. And the 85 also includes the unlimited mileage battery warranty.
Provided that Tesla is able to flesh out it's supercharging plan completely, and continue to make it financially viable to make them free (and convenient) for the long term, the supercharging infrastructure is an immensely valuable part of the equation... both to Tesla and for owners. It really is a remarkable strategy.
