Then the best is probably to do your own survey. I am not sure that what is
being observed in an "undisclosed location" would have much weight with your
management.
You can rent a Dranetz for a couple of months and install it a week at a time
in carefully selected locations and get data that you can use.

The problem is that while the frequency is going to be pretty much the same
anywhere on the same grid, the voltage is not. Knowing the voltage at some
point in your state (or another) is not all that useful. They may record it,
but I am not even sure it would be worth saving in a database.
Well, I design systems that we send out all over the world.
I have various spec numbers that indicate some rather optimistic tolerance.
For example, I have measured actual outlets in the US at 70VAC and 142VAC,
which is well outside the published tolerances.
I get a lot of flack from management when I try to use those numbers as
operational limits instead of the utility published ones.
Some empirical evidence from a third party would help a lot.
We want to design systems that "Just work".
