I would agree that these containers probably not related. That looks more like what you see when a store like a Meijer might be doing some form of interior remodeling.I have a hard time believing that that's related. There's too many containers for it to be materiel for a supercharger installation.
Appears 12 (250kw) Superchargers are coming to Florence Kentucky Meijer near I75/71.
Boone County Kentucky Planning Commission Notes from 11/6/2019, I believe this was approved on 11/20 but still looking for the documentation/notes of that meeting.

Great location for through travelers. Lots of places to eat and shop within short walking distance.
Drove past this site on 11/21/2020 - nothing happening. As a prospective Model Y owner, I know this is one I'd use a lot. Good location for the tri-state.
