Typical Cost for Decommissioning and Removal of O/H transmission lines.
Typical Cost for Decommissioning and Removal of O/H transmission lines.
(OP)
I am trying to find a unit cost for decommissioning and removing of O/H transmission lines. 2016 PG&E Final Generator Interconnection Unit Cost Guide has the following:
Double Circuit (per mile, $x1000)
69kV = 420
115kV = 420
230kV = 650
Those published values seems high for removal of lines and towers on typical, flat terrain. I was curious if anyone has additional cost estimates for removal of O/H transmission lines that can collaborate.

Can you provide some more background information in terms of the general scope of work? I'm assuming that the OHL removal includes removal of the tower foundations (possibly a huge cost)? Is there any requirement to re-use the existing right of way (RoW), and does this RoW have any possibility of soil contamination? What kind of conditions are you working with (environment, location, access to the location).
There is no easy answer to this question.

Total distance is ~3.5miles of line, but as mentioned, looking for typical unit costs.

the costs you mentioned in [1] are really high for decommissioning; maybe they are refering to installation costs.
Here, in Europe, I would roughly estimate something between 50 and 100 k€/km for a 230 kV double circuit OHL.
