Just wanted to share my 0.02 on the recent news of GM joining.
TBH, the financial implication to TSLA remains to be seen (I'd touch on this later), but as a Tesla driver, I think this is a huge plus.
The idea is simple... before Ford and GM joined, Tesla could only build SC sites taking into account the usage of Tesla drivers and its fleet of cars. With Ford and GM... and what I expect ALL EV carmakers joining on board, Tesla is able to justify the investment of many more supercharger sites as the TAM just got so much bigger.
This is especially true for markets where it's currently underserved and the reason is that there is just not enough demand. Think markets such as AK or less populous states/provinces. They simply did not have the demand yet to justify building a site that everything accounted for, might be a million dollar investment. So expansion would be slow and only concentrated in major routes/cities.
And I believe that with the added potential demand, Tesla... with its megapack and solar products, can come up with some pretty clever design for smaller or more difficult routes to bring so much power in. Think a SC site in the middle of nowhere with nothing but a megapack, Starlink and a solar array to power 2-4 superchargers spots. And this goes far beyond just Tesla's own investment. They could put up such a package and allow 3rd parties to invest in such an infrastructure.
Now, it's not all pessimistic on the financial side either. I've mentioned it before... I believe around the time when Apple Car was rumored. It is in Tesla's best interest (both its mission and finances) to provide everyone with its own hardware. This goes for NACS, FSD, drivetrain, BMS... so on.
It's all about economy of scale. If Tesla were to design and invest in something new, but could only rely on its own fleet to spread the cost, it would have to model its projections of financial feasibility on a smaller scale. However, if it could sell all those parts/software/services to all the other players in the world, it would have a scale like no other. Even as Elon had mentioned... TSLA is providing this hardware at cost... it would still benefit TSLA greatly as their fixed cost can be spread onto a much larger scale. This is truly where I believe Elon's comment on Tesla being "worth more than Apple and Aramco combined" one day going to come from.
If TSLA is the frontrunner in EV world, and the future of transportation is EV, and Tesla gets to provide most of the major components in EV, this is something hard to grasp now just how big TSLA would become one day.
I more-or-less agree with you, but there's some snivvys that could be addressed.
First off: The major assumption here is that the World Is Going to BEVs. We kind of know this: Fundamentally, a BEV is a simpler machine than an ICE: Fewer moving parts, much simpler drive train (no transmission, to speak of, for example). The only reason it's not cheaper to build (and I think we've passed that point now, what with Tesla M3's crossing the price of a Toyota Corolla) is that the Manufacturing Powers That Be haven't had the time to optimize the manufacturing of BEVs to the same extent that they've optimized the manufacture of ICEs. Finally, in this paragraph, it's obvious to one and all that BEVs are
cheaper than ICEs to run around the landscape. These, I dunno, "economies?" (they're not of scale) are going to drive ICEs out of the market; don't let the door hit one on the caboose on the way out.
Having said that: Hydrocarbon Fueling Stations Are Not Going To Make BEVs go. Yeah, people are going to have Wall Connectors in their garages, on the sides of buildings, strung around parking lots, and all that: But we're definitely going to need a boat-load of DC fast chargers everywhere. Think: Apartment Dwellers.
Worse, it takes more than the 90 seconds or so it takes to fuel an ICE. So, while a great number of the cars will be happily charging away at whatever counts as $HOME, figure that everywhere one sees a gas station, figure that roughly that number of locations will need DC fast chargers as well. (Figure: +5%, -50% of the numbers of gas stations as a rough guess. That's still a heck of a lot of charging stations.)
Tesla isn't going to do this on its own. Nice if it can.
Right now Tesla is aiming for a 10% profit on a SC business. At this time, in this place, the Tesla's SC network is roughly doubling every year. That's why we're all paying 3X home electric rates when we buy electricity at an AC; a good chunk of what we're paying is going to
New Superchargers.
And the likes of Chargepoint, Electrify America, and Blink are also moving into the DC fast charging space. Yes, they're charging about as much as Tesla. They're at least partly funded by the capital markets (stock, venture capitalists, banks, governments) to get started and get their hardware into place. Most of these non-Tesla DC people appear to be shorting maintenance so they can grow even faster (or pay the C-suite more dough, even if it kills the company. It happens.).
But that 10% profit? Supermarkets operate on less profit margin than
that. Given competition, 10% profit margin isn't a bad business to be in.
What I see: In the near term over the next few years, Tesla and the Dwarfs are going to be running around installing DC fast chargers
everywhere, because, by gum, one would have to be both blind and stupid not to realize that there's going to be a rush of BEVs to use such stations, and
that's happening right now.
(As an aside: Given the oh-so-wonderful-way that pointy-headed bosses think, anybody want to lay bets that we
won't end up with an overbuild of DC fast chargers? Think about all those rent-a-bikes in junkyards, stacked 60' tall in China.)
At some point, the market is going to become saturated. There won't be a point of installing SC's all over the landscape when there aren't increasing numbers of BEVs to use them. Which means that capital costs are going to drop. And, if one has competition with multiple DC providers, that's when the price of charging will come under pressure and drop. My guess: We'll go from 3X home charging rates to, what, 1.5X to 2X home charging rates.
Which will make charging BEVs even cheaper, a good thing.
I don't think Musk and Tesla actually
want to become a monopoly. The landscape, when it all settles out, will be a bunch of DC electricity providers, competing on price and availability. I figure: Ten years. But the real, live, Adam-Smith-was-here markets will decide.
The nice thing about everybody on
one standard? No funny bugger stuff about locking up a particular BEV to one provider. Cheaper for the consumer.
Wonder if the EU will come to grips with this.
