Tesla Supercharging Sites Ranked By kWh Usage. Top 5: Fremont, Hawthorne, Gilroy, Folsom and Harris Ranch

Here is something we didn’t expect to see at Tesla’s HQ – a Supercharging dashboard that pretty much tells us everything we always wanted to know about the network…in real time!

The dashboard displays all the current and coming soon location in the US for Tesla Supercharging, as well as lots of other interesting tidbits.  And something you can’t find hosted online.

Here are some highlights as of when this picture was shot last week:

  • Total Energy Delivered: 1,382,822 kWh
  • Miles Charged: 3,950,921
  • Gallons of Gas Offset: 158,307
  • Numer of Charges In Last 7 Days: 1,576

The dashboard also shows the growth rate in the usage of the supercharger system as well as the usage per station.  In total, 32 active Supercharging locations are being ranked in real time on the dashboard (Tesla website currently lists only 30).

Overall the best performing stations can be found in Fremont  (as one would assume it would be located by the Tesla factory), with Hawthorne nipping at its toes.  Worst performing station?  Glenwood Springs, CO.

As of interest:  The most popular amount of charging done at a station also appears to be between 30kWh and 40 kWh, with 20kWh-30kWh coming in second and 40 kWh- 50 kWh third.

Very cool. Wish this data was available online!

You would think that placing one in Vegas would be pretty obvious.
One near Yosemite, one in Reno.
I’d work on cost optimizing a charge station to extremes and then just put them everywhere.
That would make GM feel warm ALL over 🙂

As mentioned in Eric’s story last week, a lot of the casinos in Vegas are placing Tesla compatible chargers in the Valet areas, so people who valet their Teslas can have them charged while they stay.

There is a supercharger station scheduled to be installed in Primm, NV (stateline between NV and CA on the I-15). This would allow for an easier drive for those in the 60kWh model who might otherwise have range anxiety between Barstow and Vegas. And there is an outlet mall and restaurants there for people to occupy themselves with while charging their car.

Tesla’s model seems to be avoiding placing them in major cities (their HQ excepted) because they’re not designed to allow people to charge their car there all the time for free. They’re designed for extending the range of the car for highway travel between cities.

I *do* like your idea about putting them at or near national monuments/parks. Power access and RoW issues might be difficult, but being able to charge at Yosemite, Yellowstone, the Grand Canyon, Mount Rushmore, etc. would be a big PR win for Tesla.

Anton Wahlman

I still don’t see many of the Vegas casinos having chargers. The only ones placed in the free self-parking areas on the strip appear to be at Venetian/Palazzo. All the others are in valet areas, or otherwise nonexistent.

Anthony Fiti

Putting the chargers behind valet is a more efficient use of equipment. You might be partying or sleeping when your Tesla is hits 100% charge, so the valet runners can take it off the charger and park it and hook up the next Tesla to be charged, instead of waiting for the owner to come down and move the car themselves from a public charger. Many casinos now have several Tesla chargers (10-20kW) behind valet. I just took a back-house tour of the Palazzo last week and I discussed that with them.

There is one other public charging station on the strip – at the Mandalay Bay Shops, there are two 3.3kW chargers near the valet but are open to the public.

Anton Wahlman

Some persons are allergic to the idea of letting a stranger into the car, and therefore boycott the notion of a valet.


Fremont isn’t a major city


Though Hawthorne is just a bit south of the center of Los Angeles.


Is it sad that I knew exactly where Primm was, on I-15, because of Fallout: New Vegas?

I guess we know which 12 superchargers are the next ones to go online! It looks like the I-5 corridor will be complete, surely some intrepid folks out there will go from SD to Seattle and back once the stations are open.

I did an extensive survey of the DCFC Chademo chargers on I-5 north of Los Angeles
in california:


Good news though, if you can make it to the border of Oregon, there is one in Ashland.

Electric Car Insider

I just got in to San Diego last night (Monday), having left Seattle on Thursday. In the spirit of Robert Pirsig we wanted to make good time, but for us this is measured with the emphasis on good rather than on time.

The only stretch without supercharger coverage is Grants Pass OR to Redding CA. If you charge overnight in Grants Pass, you can make it to the supercharger in Corning CA. Since Grants pass is 420 miles south of Seattle, most people would be ready to stop for a good rest about that time. Ashland is a better destination, but unless someone is really hypermiling (driving more effficiently than 65 on cruise control) a S85 will not make Ashland.

From Monterey to San Luis Obispo I drive down Hwy 1, which turned out easier range-wise than I thought it would be, given the numerous ascents along the hilly coast route.

I’ll be returning in the spring and taking more time. Anyone along the route interested in a guest drive is welcome to drop me a line. Contact page on the web site.

scott moore

Does this imply that Tesla owners can pick their charge rates? Or that most charge stations are still below 40kwh?

Dr. Kenneth Noisewater

That’s quantity of power delivered, not necessarily rate or connection time.

AFAIK the initial buildout for SuperChargers use 90kW, to be upgraded to 120kW. So someone getting a 40kWh charge would be SuperCharging for 30-45m.


I wonder what these people are doing during that time? Hopefully there’s stuffy by all/most of the chargers.

If they put Wifi at them, you could maybe get some work done on a laptop without having to use 4G.

What about a car cleaning service for say $10? They could clean your car (not hose it down), and vacuum it out while its charging.


I believe only Hawthorne (Tesla HQ) has nothing.

Others you have something nearby, though not necessarily 24 hours.


The supercharger in Fremont has almost nothing nearby. If you’re there during factory hours you can go into the lobby and have a coffee, and there’s a taqueria a 20 minute walk away.

That’s another prove, that the question how long does it take to charge the battery from 0% to 100%, is irrelevant, because this happens very rarely. The automakers should better use “range charged per 10 minutes charging” for marketing, because that is what you need to know for real world daily usage.


Trouble is, your mileage may vary. The distance I can travel in my Leaf with 1kWh can vary from 2-6 miles depending mostly on speed and weather. But it will always take 7 hours to charge from empty to full.

Anthony Fiti

Another problem is that the charging rate depends on what state of charge the battery is at. Going from 0% to 50% is much faster than going from 50% to 100% since after 80% state of charge, the charge rate slows down dramatically because of the chemistry involved. Tesla’s cars might be able to charge an 85kWh battery at 120kW for the first 30 minutes to provide 60kWh of energy, but after that it slows down to 40kW for the remaining charge (another 30 minutes to top the battery off).


Edmunds article from 10/7/2013, but notes it was a couple of months before:

60kWh owners are more likely to be stretching, but the network gets filled in there should be shorter hops that could allow drivers to leave before they’re absolutely full. Also depends on total trip length, destination charging etc.


There’s some big discrepancies between the video monitor and the website.
Check out Texas and Virginia.


So, can anyone give me a ballpark figure for the cost of 1,382,822 kwh of energy in USA.

Jay Cole

Well, if this was based on the average rate in the US (12.61 cents per kWh in July), it would be $174,373

…but looking at the map and the usage skews to California (where the average was 16.71 cents per kWh), I’d say you have to gross up the average to about 15 cents….or $207,000ish

Dr. Kenneth Noisewater

At an average cost of 11 cents/kwh, times it by .11 to get $152110.42 , which is the retail price of ~72 installed SuperChargers (at $2k per 60kWh, or included with 85kWh).


You guys have some high utility rates. I think the price is .05 to .08 cents / kWh in most of the country?

And what about when they solar offset the charging stations? Also; read up on “solar city”.

Brian H

No, you’re off by a factor of about 100. It’s around $300K/Supercharger w. Solar Canopy. A supercharger is the actual station, not the installed in-car charger, which is a rectifier (AC/DC converter), not used when using a SC, because the station consists of 12 of them, stacked in series.

Brian H

A supercharger is also not a HPWC ($1200 in-house connector) or the charge to enable a 60kWh car to use a Supercharger ($2500 upgrade).


Interesting to see their “gallons of gas saved” assumes 25 MPG.


Completely reasonable for an ICE vehicle the size of a Model S.


Fremont and Hawthorne are the two Supercharger sites that are the most “in-town” and also have the highest usage. Probably not a coincidence. They are also the most likely to be used for Tesla owned or pre-delivery vehicles. People on TeslaMotorsClub talk about the etiquette of in-town people at the Hawthorne and Fremont locations yielding to people who are travelling and need the charge to get where they’re going.


I”m curious to know what software Tesla used to create this dashboard. IBM Cognos? Qlikview? Tableau? SAP Business Objects?…

Electric Car Insider

Grants Pass Supercharger now open. Mt Shasta Supercharger appears finished and ready for turn-up.


1,382,822 kWh divided by 3,950,921 miles gives 350 watt hours per mile, or 95.43 MPGe (from power in to the charger, or from the power plug to the car? Probably the latter)


350 Wh/mile seems about right.
If this contains the charging losses, sounds about right.

For my Volt (lighter car, lighter foot) – that is about 12.5 kWh from the wall, I can get 40-50 miles. That is between .25 and .31 kWh/mile. We know the Tesla has a history of its vampire drain so that may be why their number is 350 Wh/mile.

“Numer of Charges In Last 7 Days”?
Blow your nobse.
