That's just a link to the thread. I think @gmax137 is asking for a link to information about underground TLs...
But it's not the really high TLs that need to get buried, right? It would be lines that are at tree-height that are the problem, I believe. @anorlunda is that right?
I'm not so sure; the high voltage lines sag quite a bit in hot weather; when I lived in Florida, FPL would deenergize certain lines running through the everglades because the sag put the lines too close to the sawgrass.But it's not the really high TLs that need to get buried, right?
Not too many everglade regions in Cali, IIRC...Which brings up an issue, how do you bury lines that cross terrain like the everglades?
Yeah, I wondered about that as well. Getting the EIR/EIS done for each mile seems like a big or sometimes impossible task. The 2nd link that I posted says PG&E buries about 70 miles of lines a year now, and wants to increase that to 1000 miles per year.Aside from the physical difficulty, getting an Environmental Impact Statement for work like that would be impossible in today's world.
Sorry, but the link in that post is to this thread. We could still use a link to the California proposal.
The biggest problem is lines that can contact branches. However, even tall lines can be toppled, or they could rain down sparks in case of a short circuit. So tall lines are less of a fire problem but still a problem.But it's not the really high TLs that need to get buried, right? It would be lines that are at tree-height that are the problem, I believe.
Indeed, the 2003 blackout in the NE was triggered by tall lines in Ohio that sagged into trees that were not trimmed back enough. Double contingency, sagging lines and overgrown trees.I'm not so sure; the high voltage lines sag quite a bit in hot weather; when I lived in Florida, FPL would deenergize certain lines running through the everglades because the sag put the lines too close to the sawgrass.
It's not just the height. In significant events it is more related to proper maintenance, things like failed insulators (supports) or insufficient tree trimming. There is also the question of design and construction costs. Most power lines are uninsulated wires, so if they touch a tree branch, bad stuff happens. So there are ongoing projects to convert to insulated wires.It would be lines that are at tree-height that are the problem
PG&E's press release is linked, below. It doesn't go in to specifics, but it's all I found on their site.Is there a source describing the proposed changes in California? What exactly is being planned? I think this thread needs something specific to discuss. I didn't see a link in the parent thread.
Conscription was the norm years back, but it is still part of the law.They're all heroes, in my mind. The firefighters on the ground slog up and down steep terrain, working axes and shovels in the heat.
The province’s Wildfire Act authorizes B.C.’s fire officials to “order a person who is 19 years of age or older to assist in fire control.” The person has to be “physically capable of doing so” and have skills that “can be used” to fight fires — but this technically applies to anyone who can wield a shovel or a pulaski.
The Act, passed after the record-breaking destruction of B.C.’s 2003 fire season, also allows the B.C. Wildfire Service to commandeer vehicles, equipment and even whole private businesses.
The memoirist Barry Cotton similarly recounts a 1949 wedding in Vancouver being derailed because the best man was “press-ganged into fighting a forest fire.” With the press-ganging occurring in a region without telephone contact, the best man’s fate wasn’t known for several days.
The PG&E press release does not give a completion deadline. It says only "multi-year." Can't get much looser than that.The daunting project announced Wednesday aims to bury about 10% of PG&E's distribution and transmission lines at a projected cost of $15 billion to as much as $30 billion, based on how much the process currently costs. The utility believes it will find ways to keep the final bill at the lower end of those estimates. Most of the costs will likely be shouldered by PG&E customers, whose electricity rates are already among the highest in the U.S.
Yup. They have proven themselves untrustworthy, IMO. PG&E in particular has a reputation of awful management. OTOH, that's no much different than any "too big to fail" publicly owned company. Their job is to make their stock price increase and/or pay dividends to their investors, delivering power is just how they achieve that goal.It also appears that PG&E's customers don't trust them any more. So no matter what they say, it won't be believed. It is a real problem with regulated monopolies. How do you fire a regulated monopoly? Utility laws are highly complex. They are not treated like normal corporations under the law. Good thing too. We need them to keep operating even if bankrupt and even if the executives are jailed.
