I've been on the needing one side before and it did suck. You are kind of helpless. My neighbors just said no. I eventually bought the farm from one of them so it was mute.
There were lawsuits prior to my ownership over the access easement I had (NO utilities) so the one neighbor was already angry about it. So, there can be headaches.
No idea how the land lays out, but if there was some part of this guy's land that your FIL wanted and the power runs along an edge, you could do a land swap. To your advantage only and not just a 1:1 (and make the other side pay for all surveys, legal, etc.)
