It used to be generating companies in the states were obligated to provide power at a voltage and frequency equal to that of the legacy systems they installed, if said legacy systems were powering some industry that relied on those variables.
About 20ish years ago, I read of a cooper in New England that had equipment that ran on 25Hz, because that's what was available when they started. Since all of their equipment was wound for 25Hz, the local electric company was obligated to provide that.
No idea if they're still around.
