In all the conversation about PG&E's looming bankruptcy, I feel like Californians grossly underestimate the costs of adapting our energy grid to climate change/wildfire. It's $4-5M/mile to underground lines, $5K/stump to remove hazardous trees. PG&E did 451K of them after 2016.

PG&E gives a $3m/mile estimate to underground distribution lines. They have 81,000 miles of overhead distribution lines, which means full undergrounding would cost around $243 billion. Transmission is even more expensive. It's almost unfathomable...http://www.pgecurrents.com/2017/10/31/facts-about-undergrounding-electric-lines/ …

Yeah, my $4-5M estimate is from a more urban area. I don't know rural costs.

Yes but what if the real problem is that PG&E linemen are featherbedding the shit out of the work and those costs can collapse 10x under new management?
-
For the tree removal part, you can get quotes from lots of different contractors that have no affiliation with PG&E whatsoever, so I think those costs are accurate. PG&E hasn't even really been undergrounding anything for awhile, so who knows for the second?

Yes - it’s expensive to underground power. So how do we do better? In urban / forest boundary? In hurricane prone areas? Great works project admin?

The more solar and batteries we have across homes in communities the less transmission wiring is needed1

To say nothing of the pending gas-line repairs.

I live in the woods/forest, and PG&E has done more tree/branch clearing over the last 2 years than they have in the 8-9 years before that, combined.
