I had heard Tesla wasn't paying the owner until the site went down the other day and someone said it was between the son and dad. I wasn't aware of that until like 2 days ago. It was news to me! Apparently old news! haha

That's what happened in 2019. If the same thing happened again, Tesla needs to get out of Beaver or someone needs to take away dad's keys because he shouldn't be driving anymore.

Oh yes, that was just someone filling in on what happened last time. This time it was just the transformers going out as they were overloaded.
I talked to a gas station employee a weekish ago, he confirmed that they overloaded the local grid with all 32 stalls running, half the town went black apparently. They have 24 stalls now and I think the local electrical company is working on the grid so that doesn't happen again.

That sounds a bit odd - definitely poor engineering on the grid operator side. The superchargers would be connected back to the grid through a transformer which would be the responsibility of the grid operator. The transformer and grid would have been engineered by the grid company to perform to the required capacity/standards.
Almost certainly, it's not about capacity. Very likely it's an issue with harmonics and power oscillations. Planning for and dealing with this is the real engineering part of electrical engineering at the distribution and grid scale. And it's something that will often need some finer tuning or adjustment that is only apparent after everything is connected and running for the first time.
Were there 5 musical notes heard right before the town went dark? Just sayin'.
Fully pinned, all 32 superchargers could pull 2.4MW; that's a pretty significant load for a small town. I'd hazard a guess they blew a fuse or tripped an auto recloser on one or more of the phases and being that the substation is on the complete opposite side of town, probably took out a lot of other customers.
The utility company probably knew it could be a problem, but may have just been caught off guard by how quickly it became a problem.

I can imagine them... 'EV chargers that actually get fully utilized? I don't think they exist.'
Poking around on streetview, there doesn't seem to be much more than light commercial in Beaver, so with some back of the napkin math, typical load is probably somewhere around 4-6MW.

This is the sort of problem that may require a fair bit of engineering time, ordering, scheduling, etc. Could be tomorrow or months away.
A friend was just at Beaver today- and the old supercharger ( the 8 original V2 ones) are all covered and presumably off line, The Car wash structure was also torn down. Not sure what's going on there- anybody know?
Sorry, I posted this on the local Facebook group and forgot to post it here.
The Chevron owner saw such growth in the superchargers, he decided to lease more of his land to Tesla. So they are adding another 24 chargers. My hope is that Electrify America, EVGO, or ChargePoint also come in and install a station there.

Wow- that is cool- I guess that means they solved the power problems when all the station are in use?
just curious, did you meet with the chevron owner? how do you know that?
