The large slab gets both the Supercharger cabinets and the distribution center.
So what's the 2nd empty slab for?
Good question...maybe I got excited and jumped to conclusions. The transformer there could be an existing transformer for the Meijer's and the second, empty slab could be for a new transformer serving the Supercharger Site. That does seem to be a long way over to the Meijer's for their electrical feed.
Hmmm...maybe more than a couple of weeks.
