That seems way oversized for the Supercharger site. A close-up picture of the transformer label would be helpful.

And you are correct. I think. The truck moved this morning, and i see no activity at the Supercharger location.
I'm sorry if I got anyone's hopes up.
I don't think so - the pad is about as wide as a truck, and that whole assembly of heat sinks is just cantilevered out.
Regardless, it looks like this is not the transformer for the Supercharger.
How big would you expect a transformer supplying 3.3 MW to be?
I was going to get a picture, but as I noted above the truck is gone now.

How did you arrive at 3.3 MW? (Rhetorical question; you did (250*12) + (75*4), which seems logical but is incorrect)
Each V3 Supercharger cabinet has a maximum grid input of 350 kVA. Most 12-stall V3 sites get a 1,000 kVA transformer (1 MW). Even with the four Flo units added, you're at 1,350 kVA. I would expect a 1,500 kVA transformer although it wouldn't surprise me if they called it good enough with a 1,000.

Yup, it was supposed to be 3.2.
So the maximum of 250 kW cannot be achieved simultaneously at more than a fraction of the stalls?
It's complicated and depends on the installation. 4 stalls are fed by one cabinet, but all (up to 7) cabinets can share power with one another via a DC bus (up to a limit - 575 kW?). So yes, more than 250 kW can be achieved at multiple stalls simultaneously depending on the configuration and the maximum AC input for the site, assuming the site has no solar or battery storage. If the site does have solar and/or battery storage, that adds to the available power on the DC bus.

Western Canada Superchargers
Perhaps it became the West Vancouver, Delta, or South Surrey locations once the location was more fleshed out, all of those seem newly added this round. @Xelloss99 FYI the South Surrey one has been on the list for... I'm guessing 9-12 months. It seems to have replaced what was originally a...

Beat me to it! I noticed there were people working on it this afternoon after 5, right up until 10pm.

Those are the Tesla contracted supercharger installers, not Hydro guys, which makes sense because unless it is an emergency they wouldn't be working after hours
When I chatted with those guys at Cache Creek they said someone else from back east needed to fly out to approve the install. He probably will make a big swing and check Merritt, Cache Creek, Vernon, and maybe Salmon Arm at the same time. Then swing up to Williams Lake and PG?
Just guessing here.
Now I wonder if Hydro can just install the transformer and turn it on, or if the Tesla electrician needs to finalize the connections after that again. So where is the final "on switch"; in the Tesla cabinets? @Big Earl ? If so I don't think BCHydro has access to them, so they would have to install the transformer and then another visit by Tesla electricians to finally turn them on?
edit: looks like he is already here Supercharger - Salmon Arm, BC
A person from Tesla Energy will activate the Superchargers during the final commissioning process. The power switches for each stall are located behind the small lockable cover on each Supercharger cabinet. Each cabinet also has its own disconnect switch in the switchgear panel (or an external disconnect, depending on site configuration). Tesla will likely send someone out to commission all of the new sites at the same time.Those are the Tesla contracted supercharger installers, not Hydro guys, which makes sense because unless it is an emergency they wouldn't be working after hours

Or with a 750kVA…. Who knows with BCH. Transformers can be peak loaded at 125%. The chances of peak load (all stations at full power) is essentially 0.
When I was involved in building a new manufacturing facility in Surrey with 1600A 600V main switch gear. BC Hydro only installed a 750 kVA. We blew it up within 24 months as our sustained demand was around 1000 kVA. When talking with the BCH linemen they said that this is extremely normal for them to do this. We luckily got a 1500 kVA as it was the only size close enough in the lot.

Here’s a couple more from the FLO fast dc chargers for interest sake
With those Flo units only being 125 amps, Tesla’s charging superiority is really going to be on display at these locations. Imagine charging your non-Tesla long range EV for over an hour at <50 kW and watching Teslas come and go every 20 minutes at over 150 kW average.

Salmon Arm is live now, so it won't be too long before this one goes live too!

The transformer is installed and the Tesla commissioning guy is here. He says it should be done for sure by Friday, probably before that.
