Cost Estimation O/H lines (4kV and 13.8kV)

Cost Estimation O/H lines (4kV and 13.8kV)

Cost Estimation O/H lines (4kV and 13.8kV)

(OP)
Can anyone give an estimate or ballpark amount per mile (or km) for overhead line at 4.16kV and 13.8kV? (Capital + installation.)

I know it is tough, so many variables including location, terrain, but I just want a rough guide. Assume ACSR, pole mounted line just running along side of a road. No transformer, or additional equipment.

Is there any resource, books etc that have this sort of info?
Would be super helpful when I need to give a dollar amount for installations like this.

Thanks,
Majesus

I would suggest calling some local contractors.  They stay in business by knowing what the costs are.

Single phase?  3 phase?  Size of conductor?  Depending on if you're talking about a single phase 1/0 ACSR or 556AA three phase line you could be anywhere from 10's of thousands of $ to 100's of thousands of $ per mile.  

Really way too many variables for a "back of the envelope" number to be given here.

I would concur with dpc.  Local contractors would be your best bet for a ballpark number once you tell them what you're looking for.

Thanks guys :O)
Will make some calls.

RE: Cost Estimation O/H lines (4kV and 13.8kV)

For planning purposes $100K (loaded) per mile for 3 phase 13.8 kV should cover you.  There are many variables, but that number has worked for the modest sized utility I work at (our service territory is roughly the size of South Carolina).  Of course, if you don't have the same amount of rocky soil that we have here you can probably come in at $60K per mile or so.  

Keep in mind that a single 40 foot pole is running at least $1000--just to purchase it...you can rough out the numbers with a bit of research on line.  Go to alcoa's website to get the conductor cost.  Figure a four man crew can put in maybe three or four poles a day and you can see what the labor costs start to look like.  Labor is a surprisingly large component of line construction costs these days it seems...

Thanks Tlrols,

This is going up in the North, after talking to a few contractors, and with terrain. I had a "planning figure" of $100/m ($160.9k /mile).

Glad to get the extra info Tlrols,
Cheers,
Majesus
