From what I heard at the dealership yesterday, the grid here is "struggling to keep up" as a result. I don't know how true that is, but he did talk me out of spending several thousand dollars on a faster charger for my bike (6kw -> 12kw), claiming it would actually charge slower since it can't negotiate at peak rate pretty much anywhere in the state.
I would usually be more sceptical, but this guy is paid on commission and basically talked himself out of a bigger paycheck.
