None of these corner-cases do anything for your arsonist analogy. Whatever else one thinks of the utility, it is not plausible that either it or its employees intended to start a fire.

Talk about missing the point ...

Your ellipses aren't making any case for that proposition...

You can do simulations, either run it in forward or reverse. Pick a random town, burn it down, run the flame front backwards and find the paths and lines that caused it. Then look at the probable failure rates of those lines. Run it forwards, pick and event and allow it to run its course. When designing simulation runs there are bunch of dimensions to consider * Fidelity or simulation resolution, spatial and temporal…

OK. I like the increased utilization of simulations idea. Your Option A is basically how it is done already for Public safety power shutoffs: they (PGE) have an extensive forecasting department, and they de-energize certain areas for risk based on their analyses. It doesn't work all the time: E.g. Camp Fire [2]. B isn't really an option when many of these incidents occur overnight. Otherwise Cal Fire already fly's th…

You showed your agenda too soon!

These are all tactics, PG&E had no strategy other than decide by committee so they couldn't be responsible for the resulting deaths and losses.

There are so many folks trying to slip their agendas into the remedies in this discussion. All of those are literal smoke screens for the greed driven structure of PG&E.

PG&E didn't start doing meaningful shutdown on lines until after the Camp fire.

Climate change shouldn't be used as a get out of jail card free card for catastrophic events like this. PGE has a very long track record of neglectful behaviours. From leaking chromium into drinking water in socal, san mateo gas main explosion, and the electrical fires in northern California. There is something very wrong with how PGE approaches it's infrastructure and public safety. It would happen regardless of cli…

Assigning them unlimited liability for catastrophic wildfires leads to the unintended consequence of making it risky for them to run power at all during high fire danger conditions, so they turn off power in these areas.

Slaps on the wrist have the unintended consequence of a town burning down and 85 people dying.

They've been willfully negligent and reckless to the infrastructure they own to service their customers. In this case we're not even talking about tree trimming, we have a 100 year old tower. It's obvious it will fail soon, there should be an internal maintenance program to replace/update it. There are no such programs, PGE operates in a way that there would never be such a program. PGE should be held liable for pred…

They've been willfully negligent and reckless to the infrastructure they own to service their customers. No doubt, but I'm just pointing out the reality -- make them responsible for any size fire set off by their equipment, and they will respond by turning off electricity during high fire danger periods. This isn't something that "might" happen, this is exactly what did happen. So simply assigning more liability is n…

That's fine then, have them turn it off during periods of high fire danger. Massive wildfires also interrupt electrical service.

Are you suggesting it's a good thing that they run their poorly maintained lines with a high chance of causing a fire during periods of high fire danger?

People want power, but they also don't want to die in a fire.

1,2,3 are maintenance 4 is unavoidable 5 is maintenance 6,7,8,9 are not PG&E 10 is "bad management"? Sure, that's a root cause, though a massively vague one. 11 is not PG&E So yes if you're concerned about external problems then there are things you can mention. I'd never argue that housing location and fire management and climate aren't factors! But in a discussion of what PG&E did wrong it's basically all maintenan…

What I mean is: the first poster in this thread mentioned a broken hook causing $16 billion in damage, but the difference between a broken hook causing $1 million in damage and a broken hook causing $16 billion in damage was largely out of PG&E's hands. > 10 is "bad management"?

That's true but they knew that and it was their responsibility and it was easy to prevent if they hadn't failed at maintenance in ten different ways.

This is definitely a failure on PG&E's part, but I'm still not sure how much sense it makes to assign them blame for this fire. The environment they're operating in is somewhat ridiculous - the forest is so dry and overgrown that pretty much any flame source will start a fire large enough to burn a huge area; this specific tower failure is basically just the thing that revealed a much larger issue. With proper engine…

> the forest is so dry and overgrown that pretty much ...

... it is impossible to maintain records of WTF they are doing.

This is an interesting argument. Maybe 10 years as a lifespan would be better than 100 years since it'd force checks every year. With the 100 year lifespan, people will always assume it can be done next year instead of this year.

Reminds me of Let's Encrypt issuing 90 day certs instead of 1+ year so that you're forced to find a better automated solution and not have a panic when your cert expires in 5 years

I wonder whether or not that's the global maximum. I still occasionally run into sites that never figured out how to use Let's Encrypt, so they don't encrypt at all.

I personally achieved completely automatic renewals (https://jrock.us/posts/rotating-envoy-certs/) but it involved some work. (It also works so well that I don't even believe it. I have to go manually check from time to time because my monitoring never shows me any errors, and there are so many moving parts that I am continually amazed that everything works perfectly.)

Other people just aren't willing to do that. They like their nginx/Apache sitting on a lonely Linux box that they ssh into once every 5 years. The cost of changing any of that software is high, and they don't have a good system for running new software, like Certbot. We definitely didn't fix that.
