Actually I was referring to the Northern Pass. The Northern Pass is a proposed high tension electric power line to bring electricity generated in Quebec down through New Hampshire to Ma and CT. They need the approval for a new right of way through the northern most two counties in the state. The fight is that nobody wants these 150’ high towers in their back yard or ruining their view. Therefore, they may have to bury them to get the approval with the state. That would of course cost the utility more money.
Sorry, I should have checked the name.
Buried electrical transmission lines are many times more costly than overhead lines. Faults are not quickly repaired and have much shorter lifespan (time between faults).
As an electrical engineer, specialized in power system, I must say you know not what you request.
It may be cheaper to build a nuclear power plant instead. Sadly, I'm only slightly kidding.
