I wonder if paying the boring company to make a tunnel for the cables would be cost effective and avoid complaints. I believe that they can bore tunnels without digging along the path on the surface.
Which is not to say they don't use TBMs - they do, but it costs a lot - this is a 200+ million project to put 3km of cables underground: https://www.nationalgrid.com/media-centre/press-releases/tun...
