Reply to comment by AKBigDaddy in Why does this state seem to lose power so frequently? It’s always related to downed power lines from trees? Or is this a grid issue? by JayBisky
> Last I saw it cost around $11500/mi to bury lines- not cheap by any means, but it could be covered in <10 years by a 1c/kwh increase statewide. Additionally, most new construction already has buried lines, no reason not to make that the standard.
Where did you see that? Because if it cost $2/foot to bury lines, the power companies would have buried all of them years ago.
The absolute cheapest per mile number I have found recently is $1.5 million to bury lines. Even in 2017, when Hydro Quebec floated the idea of burying 11 miles of lines (that didn't require any horizontal drilling, mind you), it was $4 million per mile
So if you have a way to put high voltage transmission lines in the ground for $2/foot, write Eversource and tell them because they'll be all over that.

This was in regards to poles and local service, the long distance HV Transmission isn't commonly buried AFAIK.

Doesn't have to be long distance HV transmission. Even just like 34k or 46k that would serve a neighborhood is going to get costly to bury.
