The benefits are real, but without safeguards it will be abused: police officers and, in this case, also power utility workers likely have full, unaudited access to this data. That means they'll use it to stalk and harass people, e.g. ex-girlfriends, in addition to legit uses.
This is such a common trope, and it should be fairly well-known by now how so many American cops are basically bullies with guns, that I really have to wonder why any sane woman would ever date one. Horror stories about the things the ex-girlfriends and ex-wives of cops have gone through have been around for many decades, it's not something new. I have seen a non-negligible number of women on online dating sites who have specifically said they would not date anyone in law enforcement.
