Transmission Line Cost
Transmission Line Cost
(OP)
I'm needing a good rough estimate of the cost per mile to build a 50 mile 138KV, 1272 ACSR transmission line in the central US excluding land acqusition cost? Route is straight, land is flat, mostly open range and sparsly populated. Considering wooden H-frame or concrete structures. Sorry, I know there are lots of variables.
thanks

RE: Transmission Line Cost
The land cost is the largest cost, and also legal fights because of NIMBY. Also often farmers don't want to move irrigation systems, for right aways.
The cost to install depends to access to roads, and if structures need to be assembled, and installed by helicopter.
Also there are different climents and soils in the central US, so different construction, wood types, foundations etc.
Any cost you recieve will have a + or - % depending on how much you can limit the variables.
RE: Transmission Line Cost
I think that 250,000 to 350,000 $/km can be consideredas as a (very) preliminary cost estimate.
In my opinion, in addition to land costs and authorization issues, some design criteria (e.g. number of suspension towers versus number of anchoring towers, wind and snow loads, etc..) can have a substantial impact on the cost and therefore these issues shall be decided in order to have a realistic cost estimate.

herebelow you can find a document with cost comparisons between different ENTSO-E countries; for example a 150 kV line (lattice steel towers, single 31.5 mm ACSR curlew-like conductor) in a flat rural area would cost about 270 k€/km, i.e. about 600k$ per mile.
