My home is 287 feet from the highway pole; and I had one pole in the middle of that distance on my land.
The elec company was coming thru the area replacing old, suspect poles a few years ago.
Before they got to working on mine, I asked them about replacing it with underground. The fella replied that ALL new services go underground and mine could be placed there as well. There needs to be a trench dug between the road and the house and if I'd get that done, then they'd drop me a new service to the house at no cost to me.
While I was pondering that info, he said, "Or we will dig it for a dollar a foot."
said the dude with the gimme hat.
I've MUCH better service now, due to the fact of much bigger gauge wire. No more light dimming when the furnace blower kicks in!
I had an opposite issue. The utility upgraded my area with a new sub-station of which it's feeder crosses my land to the station 2 miles away. When they put in the new substation the voltage went from 120/240 to 130/260 and stuff started smoking including my pump buried in my well. They finally came out and put a transformer set for 115/230 volts on the service for my house and it stopped.
The utility also began a right of way maintenance program on their lines cutting problem trees down and keeping underbrush controlled. That made outage from from 2-4 times a year to once every two years or so.
