The ground is not supplied by the power company. Two buildings can each be properly grounded, but their grounds can be at different voltage levels. Sometimes one building may have two different grounds. It gets fun where the outlets in one wall are grounded to one side of the building, and another wall is grounded to the other side. It's a good way to fry equipment. If you have a cable between the two buildings, you can get a voltage difference between the two grounds. Especially if you have a lightning strike in the area. And yes, I've seen damage caused by such differing potentials, as well as measured the difference between two buildings. I measured 70+ volts in one instance, without any lightning in the area (after one melted terminal). We went with some short-haul modems in that instance (opto-isolated, differential pairs).
