Don't bother. I drove through the lot a few minutes ago. There is no transformer (I thought I saw it there when I drove by this morning, but maybe I was just hoping it was there ) . There was a Tesla team there with a model Y, apparently testing some things, but without a transformer, they certainly weren't testing large quantities of electricityI'm thinking about dropping by this afternoon to see if it's working and grab some groceries. I'll post here if it's online.
