That's a very sophisticated way of saying that utility companies have some magical entitlement to say "Fuck you, pay me".

There's another answer that that a 5 year old could come up with, and happened to work very effectively for 75+ years: when the electrical grid is out of electrical transmission capacity, add more capacity.
