I would assume that since a new subdivision is already dug up the cost of implementing would be greatly reduced. Obviously any power utility in an area that has underground cables did their research and determined that underground would be the best solution. And, if it was a better deal for them everywhere they would push to do it everywhere.

Years back, probably 20 years, I researched a bit about what it would take to bury the transmission lines along the Burlington waterfront (high voltage transmission - you know the ones I mean). I found that, yes, it would be prohibitively expensive and part of that expense is due to the fact that the lines need to be cooled if they are underground. I had no idea that this was necessary. Cooling is usually done by pumping cooled oil through the conduit.

I doubt the stepped down residential lines need to be cooled by the way, I just found that interesting.
