This looks a little suspicious. It doesn't look like a Supercharger. There are too many big conduits coming out from what would appear to be Supercharger Stalls. Also, why does the big "transformer" have a manhole cover in it?
I might be wrong.
Whatever, if this location actually does have Supercharger construction, it has the folks in North Dakota and western Minnesota excited. If they build out the Trans-Canada Highway, they have a chance of building out I-94 in the U.S., which has been long promised. North Dakota is the only state in the U.S. without any DC fast charging.
It still looks
very consistent with supercharger builds. The utility transformer is sitting on top of a high voltage electrical vault, which is like an industrial sized junction box. At home you'd have it behind your dry wall, here it'll be underground. But it still needs to allow access to the connections which are made inside, hence the manhole cover.
The forms they're working on, which you think are for the "supercharger stalls" as you move down the line from the transformer aren't for the charging posts. It's a bit hard to tell from the distance/angle in the video portion but in the static shots at the end, it's much clearer that they are actually well back from the parking surface. They're going to be where the supercharger
cabinets are installed, not the charging posts. Instead of placing the cabinets all on a single larger pad, they're being space out linearly in this install. Probably due to the limited available area along that strip. This is a less usual layout for superchargers but has still been seen at multiple other locations. Expecting those to be the bases for the charging posts, it's easy to see why you'd think that the conduit looked wrong. But with the understanding that they're actually for the cabinets, with the posts placed closer to the actual parking lot surface, things go back to looking normal. The bases for the posts aren't in yet, but you can see the single conduits that will deliver the electricity to the posts, running from the future cabinet location to the edge of the lot. Etc.
