And they’re actually installing Superchargers. Wowza!!
Edit: thanks Cory for getting the location on the map

Wow, I wouldn't have thought they'd go through with putting one there
.
Guess Wenatchee and Chelan won't be getting a Supercharger since there only 31 and 18 miles respectively away.
I guess I'll have to use the bathroom down the road, since the adjacent Shell stations bathrooms aren't the best.

I just hope they follow through on the Okanogan location. That one isn't strictly needed for Hwy 97/97a travel - it's ~120 miles from Entiat to Osoyoos - but it is needed for travel on the N Cascades Hwy...
I would have hoped for: Yakima, Newell CA, Adin CA, Susanville CA, Roseburg OR, before this one went online, but I'm still happy to see these finally start construction too.
Nice to see some non-interstate locations to fill in some big areas. I am hoping for a lot more state highway locations once CT is out. That said still need places like I5 Roseburg since 140 miles from Eugene to Grants Pass.
Alright guys, the topic of this thread is the supercharger under construction in Entiat, WA.
(Sorry, but major pet peeve of mine is when people start lamenting about completely unrelated superchargers that have not yet been built)

There’s also a permit for this location now
Installation of (1) 1200A service, (2) feeders for super chargers and (1) master controller circuit

So far they have 8 concrete bases for the stalls. Too early to tell which version. V3 would be my guess.
V2 seems like it would be a waste for a new install unless they have power delivery issues. All the capital cost of construction would outweigh any cost savings between the hardware (I would think), except if they had to do major upgrades to power to the site...

So I'm no power engineer, but the permit says installation of (1) 1200 Amp Service. If we assume 480V 3-phase service comes in to the supercharger site, that would result in approx. an Apparent Power of 997.66 kVA.
So if each V3 supercharger station can provide a peak output of (250kVA) x (8 stations), would need 2000 kVA for the entire supercharger site (assuming 100% efficiency of AC to DC conversion, which isn't really possible).
So I'm betting on eight V2 stations unless they bring more power into the site, or I don't understand this correctly.
Any Electrical types out there want to confirm this?

The service from the utility generally does not equal 250 x stall count. Tesla presumes that not everyone will plug in simultaneously and not everyone will be at 1% SOC. So yeah, having the utility feed undersized like that is fairly normal. As (excluding the most extreme of circumstances) it won't ever matter.
The problem is your assumption that V3 can provide 250kW to all stalls simultaneously. With a standard V3 installation of one cabinet for every four stalls, it simply can't do that. A V3 cabinet has a max continuous AC input rating of 350kVA@480V or 430A. A 1200A service is more than sufficient to supply two V3 cabinets.

Per MotorTrend article:
V3 Superchargers get 250 kW each, all the time, so how busy a Supercharger station is will have no effect on your charging speed.
Per Tesla website:
Supercharger stations with V3’s new power electronics are designed to enable any owner to charge at the full power their battery can take – no more splitting power with a vehicle in the stall next to you.
So I'm sticking with eight V2 chargers, unless Tesla's is only going to install four V3's, or until someone provides an "engineering answer".
I think you’ve already gotten the correct answers above (the MT article is wrong, and the Tesla text is misleading at best). If you don’t believe it, then maybe check out specs for power service at other recent V3 builds (some are in these forums). I imagine you’d have lots of takers if you still want to wager that this will be a V2 site!
Technically you’re not splitting power at the stall next to you with V3. Everyone can get as much power as the site can supply. If you’re the only two there and parked right next to each other, you’ll both get max power. By the nature of supercharger, most times the majority of cars will be somewhere in the slower taper. The highest power portion of charge is also the shortest period of time.
Now if someone wants to make a YouTube video with 8 friends all plugging in at 10% or less it might be interesting to watch if power is split evenly or how it works...

Ok. You're wrong about how V3 works. It's very unlikely that Entiat will be a V2 supercharger and the sizing of the electrical service isn't evidence to the contrary.
