Teton - Yellowstone loop for Tesla project

Originally posted on another topic. I wanted to post this here to get an indication of interest.
Would anyone even be interested in doing this type of vacation with a Model S or Model X?

I am planning an EV access project around Yellowstone for Summer 2014.
Here is the route. The Teton - Yellowstone loop. 262 miles.

My family has a business that has locations in Jackson Wyoming (near the southern entrance of Yellowstone).

We also have a location on the Idaho side of the Teton Pass. That way you could recharge a Model S on either side of the mountain pass (10% grade climb)

I will be putting my personal HPWC in one location and purchasing a CS-100 (J1772) for the other location. I also think I have convinced a top ski resort in Jackson Wyoming to install a NEMA 14-50 for overnight charging.

The final step will be to get a 70-80 amp location in West Yellowstone (Montana). I am still working on that location.

If those 3 locations are covered at 70-80 amps, then the 262 mile loop should be fairly easy. Someone could recharge easily at the western or southern entrance to Yellowstone and enjoy their time in Yellowstone. The distance between West Yellowstone to Jackson Wyoming is about 120-130 miles. So there is plenty of margin there for elevation changes consuming energy. Inside of Yellowstone, most driving is between 30-40 mph so it is very efficient.

When this project is done, Model S owners should be able to handle the 260 mile Teton-Yellowstone loop easily. It is rated as a top 10 scenic drive in the USA. It hits all key spots in Yellowstone, Old Faithful, Mesa Falls, Jackson Wyoming, Grand Teton National Park, etc.

If Tesla gets some Superchargers in southern Idaho or Wyoming by Summer 2014, this should be amazing.

Here is the correct link to the Teton Yellowstone loop map.

I'd love to do the loop. You don't happen to know if Chico Hot Springs is amenable to getting amped, do you?

Awesome. That trip was at the top of my list.

Sign me up!

I'm game!

Very likely me too.

Awesome, we live in Colorado and love that area.

We spent a week this summer at Jenny Lake Lodge and did the loop into Yellowstone (in a rental car). That would be an amazing drive in a Tesla!

We would love to do this. Are you suggesting a group trip or just the charging so individuals can do this trip?

Wow, if that becomes a reality, I will drive my MS to the beautiful Yellowstone (without driving a rent ICE car)!


I am just letting everyone know that we are setting up 70-80 amp L2 charging options in this region for summer 2014. Plan your own trip accordingly.

As long as Tesla Motors gets 2 or 3 Superchargers in key areas of Idaho and/or Wyoming, it should be easy to reach Yellowing/Grand Tetons/Jackson Wyoming. It is probably one of the most amazing areas in the world and everyone should do it once.


The Supercharger map has Elon's route across the country coming fairly close. But for someone to reach the Yellowstone region, I think an extra Supercharger would need to be in either southern Idaho or southern Wyoming.

We will likely know more in the spring of 2014 if the connection will be possible for summer of 2014.

I've never been to Yellowstone, and REALLY want to get there! I'll need more superchargers in TX, OK, KS, NM, and/or CO to get to WY. Probably not until 2015, but this makes it possible!


That is so cool! I have never been to Yellowstone either. I plan to visit it once Superchargers are rolled out to the area.

As usual, Superchargers are not at the destinations, so your plan is perfect!

See you in 2015!

That's one of the trips my wife and I have been talking about doing!
Isn't it ironic that we're planning road trips with the Model S - a car which, we keep being told, is supposedly less suitable for that -, trips that we *never* considered doing with our old cars? I'm starting to think that it is actually *more* suitable for road trips, and more healthy ones at that, because they remove the "Let's go, let's go, we gotta make good time" stress factor. We know going in that we'll get a break every few hours.

Actually, it's the desire to experience more Tesla Therapy while on the road. The longer the trip, the better!

Sounds great. We plan to use this to visit the region when the superchargers get near.

Sounds great, was planning a trip out there this summer already for a family reunion. Would love to extend it to do the loop. Keep us posted on the progress.

Has anyone seen any trip planning software for EVs that takes elevation and energy burn into account?

Yes, it exists, but don't have the link handy.

PS -- I remember reading about some peculiar numbers it got from routing a car across a river, on the bottom!

Great project James. You should check with the Grizzly & Wolf Discovery Center about a charger location in West Yellowstone. I would think they would appreciate the added business and that is a place that you could spend enough time to charge up without getting bored. I will definitely be making the trip when chargers are available.

I will check it out the next time I go to the region. Likely in the spring. Thanks.

If anyone else has ideas on good locations, post them here. I will likely do a very detailed EV access map for the Yellowstone / Grand Teton Loop, similar to the Tesla Highway map that ChadS is building.

The map will include:
1) places of interest to stop
2) 70-80 charging options
3) NEMA 14-50 equipped hotels
4) best Supercharger routes to reach the region

The cost of a HPWC (80 amp max) is only $1,200.
The cost of a Clipper Creek CS-100 (80 amp max) is $2,200.

Is there any way to use a HPWC and attach a J1772 adapter to it so that other EVs will be able to use a HPWC?

If I install two HPWCs in Jackson Wyoming and on the Idaho side of the mountain pass, that would be cost effective and great for Tesla owners. But we want to also provide for non-Tesla owners in the future that might have a J1772 input on their cars.

Has anyone heard of anything like that?
We have adapters for Roadster RPC --> Model S.
We have adapters for J1772 --> Model S

What about HPWC --> J1772 so that others can use a HPWC?

The Teton Springs Lodge resort is located right at the base of the grade in Victor, Idaho, about 20 miles from Jackson. The Managing Partner is a friend of mine and I'm sure would have an interest in talking. His name is John Marshall.

Unless I missed it, what businesses are yours?

William9, ask him to install at least a NEMA 14-50 for overnight guests and we will certainly add his location to the map.

Sorry, I meant the OP, JamesM. What businesses do you operate around Jackson?

Would love to take that trip. Last of the kids leave for college fall of 2014. Plan on lots of road trips. This would definitely be one for us. Might be in my S or perhaps my wife's X (if she doesn't change her mind.)

Best of luck with this.
