Eminent domain is a little more complicated than the PoCo simply dropping a pole wherever they like. If this is your driveway and they have an easement they have a lot of latitude but if there is no easement on the deed they will have to get the government involved and in most cases you can get compensation for that easement if you are willing to fight it. Easements for individual service to a dwelling may be harder to get.
You should be aware of any easements before you buy a piece of property, assuming you are doing due dilligence.
