I'm doing this job in the east county area of San Diego,some of the lots there are gigantic (5 acre minimum size for single family residence is not rare)and as land values go up in the city more and more people are going out to the more remote and,lets say difficult areas.
The electric company will allow running a High voltage feed and a pad mounted transformer(supplied by them)to the tune of something like $40000.00.Not a really good deal for the home owner.
