I don’t know specifically for Vermont but “the grid struggling to keep up” usually means that there is a specific moment in the day/week/month at peak consumption where the production is struggling to keep up.
99.9% of the time outside of this specific moment the grid is fine and your fast charger should work fine.
PS: I am not 100% certain of what I am saying so I would be happily corrected if I’m wrong.
Every day in the world 1000 people die by accident from inhaling dihydrogen monoxide in liquid form.
Do you hear about that in the mainstream news ? Of course not!
