I get that America is big, but the amortized per-person cost is what's relevant. If something costs $10 M per mile, but there are a million people per mile,
suddenly that's not all that expensive. I'd pay more than $10 to not have my power go out for a week after a big storm that's likely to happen again in a few weeks and next year and the year after. A backup generator costs way more than $10.
The amortized per person cost is obviously not going to be constant when the demographic density and line mileage changes. That’s why it’s a foolish standard
There’s NEVER 1M customers per mile in a distribution system. There’s only going to be a few thousand per substation. Half of the line miles will have customer counts in the tens or ones.
...but... that's like, uh, how projects like this actually get financed. On a per customer (which I know is distinct from per person) and per monthly bill basis, capitalized and amortized. Why would I use a lump sum unit when that's not how it's going to be paid for, or a per distance unit when pieces of dirt don't pay money, people do?
Pal, this is just how basic corporate accounting works, something you might like to look into if you are interested in opining on what units are best for comparing capital costs.
I already responded to that two days ago in adjacent replies.
You’re also completely wrong. Utilities do not get to pass on costs to specific customers. It is, at best, just a compelling point with regulators to build it into the rate case for capital spending.
So? That just means the regulators are part of the decision. If the stakeholders (regulators plus utility managers) choose to, they can do this, and it is affordable. If it takes an act of legislature to make it work, whatever.
The point is there's no technological barrier, just made up paper barriers.
Undergrounding costs are around $1M per mile. The US has millions of miles of lines.
