Cost estimation for 12.47 kV prototypical distribution network

I am doing a research project analyzing US distribution networks. I have looked for hours for information about the average cost per mile for building this kind of lines. I know it depends on many factors such as climate, temperature, distance between clients, if it is rural, suburban or urban…

I am looking for data points, companies or agencies that have published data regarding estimated costs of building their networks, even projects of cost estimation for this kind of installations in any State. In my particular case I’m trying to estimate the costs of building some of the PNNL prototypical feeders.

I looked and failed in several agencies. For example EIA “does not publish specific data on the costs to build or operate electricity transmission lines and distribution networks. “
When I looked for transformer costs, I found some valuable information that the State Highway Administration researched in Maryland.

Fun fact: the document I've found closest to what I'm looking for (outdated, not enough information) is literally called "Hard.To.Find.6th.pdf"

I can share with you additional information as you require, and I hope it's not that hard for you.

Information about one of the networks I’m analyzing (R1-12.47-1 PNNL taxonomy feeder)

Voltage (kV) 12.5


Load (kW) 7,150
Residential Transformers 432
Commercial Transformers 12
Agricultural Transformers 8


The length of the network is approximately 30 miles.

Can someone provide data about cost per unit length of distribution networks in the US for any State for voltages close to 12.47kV?

Hi

First, you are right, there are so many factors to consider in this type of installation. Here is what i found about the costing:

Thank you very much for your reply.

I had already seen the Guide for Electric Cooperative Development and Rural Electrification, and I had seen that most of the prices are for the local communities where they make the projects happen, and not the US. Therefore it can be an orientation and I could do some kind of analogy, but with a lot of uncertainty.

The others I had not looked into them, thanks for showing them to me. I will see if I have a way to access the books without purchasing them, some of the data showed stated that prices were based on 1994 data.
