Considering that they did not put wood boxes over the pipes to protect from the winter like we have seen at the other locations, is it possible they get this done before winter?
They started construction this summer on the conduits and bases along the TransCanada from Sault Ste Marie (actually, from this side of Ottawa) across to Calgary. In the last 2 months some white boxes are appearing for the V3 support, and in the last few weeks some sites have started getting pedestals. Regina, and assorted sites around it, have fully installed pedestals only needing to be turned on. I see Brandon and Portage have just took delivery of their white boxes.
So the equipment is coming now, the trickle is turning into a flood. Rumor has it (from what a technician said?) these will be turned on in November. Expect equipment for SLP-MN in a month or two at this rate.
Also - note that once the conduits are in, they can probably do the last installs in almost any weather - I assume they have construction tents for over the equipment as it gets installed to warm the workers - they had a canopy to protect installers from the rain on another site.
The next step, which doesn't have to wait for equipment, is to pull the cables. I assume this can happen pretty soon, and at that point they will install whatever weatherproofing is necessary. Protection we've seen (like conduit 10 feet in the air because the cables don't coil well) happens after the cables are pulled.
What's missing, of course, is for at least one of these greenfield V3 superchargers to go live. I suspect they're waiting until they are all ready and have a grand announcement about opening the TransCanada. I suspect a similar big announcement about a grand opening for I94 and I29 when everything is ready.
