> SF even owns the hydro generator at O'Shaughnessy Dam.
They own the dam, but the Federal government still owns Hetch Hetchy water and land. Permission to use Hetch Hetchy is governed by the Raker Act, which stipulates[1] that SF can only resell the electricity and water through public municipal districts, not to private utilities:
> Sec. 6. That the grantee is prohibited from ever selling or letting to any corporation or individual, except a municipality or a municipal water district or irrigation district, the right to sell or sublet the water or the electric energy sold or given to it or him by the said grantee:
> Provided, That the rights hereby granted shall not be sold, assigned, or transferred to any private person, corporation, or association, and in case of any attempt to so sell, assign, transfer, or convey, this grant shall revert to the Government of the United States.
The original plan was that SF would build both aqueducts and transmission lines to SF, branches of which could serve other municipal districts. But they only ended up building the aqueducts, and contracted with PG&E to transmit the electricity. The question is, is SF violating the Raker Act? Previous administrations have said no or demurred requests to answer the question; typically the people raising the issue want the dam removed. SF claims PG&E is acting as their agent and everything is above board. But, above board or not, I've read some old articles that suggest there's a 50+ year-old understanding or gentlemen's agreement between SF and PG&E, that PG&E would give the City of SF (if not its residents) sweetheart pricing on transmission, etc, and defend the status quo in DC so long as SF didn't attempt to buildout it's own transmission lines or otherwise cut PG&E out of the loop. But if SF did do that, PG&E would lobby DC to terminate the grants under the Raker Act. From the beginning, many cities in California, and even politicians outside California, have resented the Federal grant to San Francisco, so presumably with the right trigger a very large lobby could quickly arise and demand the Raker Act be replaced with a new deal that gave other municipalities in California a direct stake in Hetch Hetchy. It's even possible PG&E comes out on top, because who's going to transmit the electricity?
Of course, that story leaves alot of unanswered questions. But it sounds plausible to me. With CEQA, etc, there's zero chance SF could ever build out its own transmission lines today; it would take untold billions and, more importantly, decades--far longer than the Raker Act would likely survive. Currently the City of SF basically pays nothing to power its public buildings (schools, etc), MUNI buses and trains, and possibly SFO (which SF owns and operates). The budgetary and logistical upheaval that would happen if the Raker Act grant was rescinded (which, again, almost every other municipality in the state would support) is mind boggling. Even if we assume every mayor has earnestly wanted to cut PG&E out of the loop and do right by SF residents' individual power bills, what sane, term-limited administrator would invite that chaos? Plenty of mayors have broached the subject, but invariably such suggestions silently stop, so presumably it's just a negotiating tactic with PG&E that both sides are very careful not to let get out-of-hand.

Even if SF lost the hydro plant outright (which seems unlikely) there's still plenty of margin for SF residents to come out on top. SVP in Santa Clara doesn't own much generation, yet its rates are 60% lower.[0]
Then there's the state-wide need to increase transmission capacity because of the switch to renewables, the future politics of which are kinda unpredictable. It's hard to imagine SF getting singled out and left out in the cold, considering the state already has many large municipal utilities getting better deals for their residents.

Follow the money. Who appoints people to regulate electricity in California? The governor. Who mentored California's current governor? Willie Brown. Who does Willie Brown work/lobby for? PG&E.
The California Assembly is one of the weakest legislative bodies in the entire nation. It's too disorganized to engage in any effective oversight or lawmaking. It's left to the people to come up with constitutional amendments to try to manage this enormous machine.
It's a beautiful state. There's literal mountains of opportunity here. It's lately all too easy to become irrationally angry at these con artists and their ruinous agendas.

Willie Brown hasn't been in the Assembly for decades and the governor directly controls the CPUC.
My understanding is the governor has to follow laws that are written by the assembly. If one wanted to constrain or force his behavior that would be a perfect instrument to accomplish it. Have I misunderstood this? If not, then this would be the reason for my comment.
Or is your point that the total lack of checks and balances afforded by the Assembly presents us no additional problems over Willie Brown's current employment?

So cherry pick the nice dense area and leave the rest of the state with the hard to serve areas?
Why should people in the nice dense efficient area subsidize everyone else via PG&E? Pay your fair share.
They're not. Rural electricity can be had in the United States for far less than PG&E's charging. Look at Hawaii, Alasaka, TVA, etc., etc. PG&E is expensive because they have to pay for negligence, homicide, stock buybacks, dividends, executive bonuses, lobbyists, and back maintenance.
It's also worth noting that PG&E's got a history of astroturfing. Back in the 00s there was a local blogger, Greg Dewar, who ran a blog called the N Judah Chronicles. Ostensibly it was a blog about Muni and transit issues, but when muni power in SF came up for a vote boy was he hopping mad. It wasn't until someone else called him out for being on the PG&E payroll that he owned up to being paid to astroturf.

1.The last time PG&E had a stock buy back was in 2006.
2. Their dividend yield was 0.8% in 2025, the average for utilities was 3% to 5%. Alaska's APTL was 2.4% to 3.4%
3. Their state lobbying for 2024 to 2025 was less than $4 million. Federal was $60k (both insignificant)
4. California AB 1054 means that almost all of their largest liabilities will be reimbursed via the state wildfire fund. They also have insurance for anything that is not covered. While this won't cover it all the amount actually owned is likely to be low.
I also checked executive bonuses and while the CEOs pay is on the higher end it's not extreme. Not sure how much other executive bonuses could really add up enough to stand on its own as a reason for high electric rates, especially since all your other main arguments seem to be incorrect or exaggerated.
Regarding "back maintenance" this is a standard expense for a utility. Do you have some evidence that it's particularly high for PG&E, taking into account the size of the state?
Why would you make the assumption that the reasons PG&E is expensive(which I haven't even checked) are mostly due to corruption, excess pay or benefits to stock holders, or that the utility has a high liability debt? Most of the reasons you gave are ones that look bad for the leadership of the utility and maybe even the state. Is it possible that due to political propaganda over the long term you default to the assumption that anything a California connected entity does is bad so much so you don't even bother gathering evidence?
Also Hawaii has much higher electric rates than CA.

HE is claiming a residential customer will pay around $0.45/kWh which is absolutely on par with PG&E. Keep in mind that HE currently charges fixed fees for electric service, PG&E doesn't yet but will add a fixed fee of $24/mo beginning next year. It shouldn't even be close. Practical Engineering covers it but Hawaiian Electric has some of the biggest challenges of all POCOs.
Peak rate for San Francisco residents is $0.71/kWh
Most people agree that we need utilities to be monopolies. PG&E, for all intents and purposes, is an arm of the state. Perhaps it’s private in some sense but we all know it’s the government. It has to abide by all manner of government mandates, there is no competition. If you want it to go bankrupt just let it go bankrupt. Whatever replaces it will be the same thing. I don’t have a solution but all the teeth gnashing isn’t going to change the fact that electricity is a government issue and whoever runs it will work at the behest of the California government and the voters.
Pass whatever rules you want. It isn’t going to change the fundamental nature of the org, which is a reflection of the voters. This is a government problem, through and through

That's hilarious. The CPUC is regularory-captured like nobody's business, and our governor has been in the pocket of the utility for as long as I can remember. I guess in some sick way that's "at the behest of the government", but it sure as hell isn't at the behest of voters.
Unfortunately, we rarely have choices in every aspect of political candidates in order to change this state of affairs.

It's not government in at least one major way: there are private shareholders which dividends are paid out to.
This incentive structure perfectly aligns with most of the dysfunction of PG&E.
So no, it isn't really comparable with a truly government owned public utility.

Why should people in the sustainable areas keep feeding the cancerous growth of worthless degenerate parasites? Serious question, as city folk keep ratholing into more and more socially destructive technologies, technologies designed to hamstring people, they lose the relative value.
Look at youtube, tiktok. Fine that's entertainment (set aside the issue of infotainment that has already infected public education). Then look at so called "productivity apps", or language learning apps. It's one thing to waste billions of collective man-hours it's another thing to lie and tell people they are learning or being more productive when you are wasting their time.
There are no mass assembly lines in the US, city GDP has been paper GDP for a long time now. On-shoring won't work without a total collapse of every culturally-enriched city, people need to learn hardship again.

If - if - people who live in the boonies deserve to have the burying of their tens of thousands of line-miles subsidized by others, it's by taxpayers, not by electric users in efficiently-served areas.
most people dont decide where they live. They also cant move. Good job instigating a class war
The difference between being taxpayer-financed and user-financed is that Ellison is on the hook for 10000x as much as granny instead of 20x. If it's a public good it should be paid by the public. A six-year-old keeping the light on at night should not incur a 120% surcharge for burying the transmission lines to a mansion in St. Helena.
This is ridiculous. What could you possibly mean? Everyone decides where they live. The cost of moving is not high, the ability to secure a job never easier.
This is a luxury belief and not borne out by any sort of reality. People have been deciding where they live for millennia and it’s never been easier than today.

Well, urban areas tend to be much more expensive to live in, especially in California. And most people don’t work in tech and enjoy relatively good job prospects.
I don't think those stats are true in California
Please note that AB 1890 which deregulated and divested electricity markets was passed during the tenure of Pete Wilson with the help of a bunch of Republicans holding the legislature budget hostage.
California has been dealing with the idiocies caused by that ever since.

In the former two cases, the cause is that something terribly wrong is happening for years. In the latter case, likely, too.

Are you suggesting Ukraine and Russia don't also have occasional outages caused by equipment failures or bad decisions unrelated to the war?
I wonder if anyone in the emergency operations center has offered up the idea that there should be more than one entity providing power...
Dunno, I think it's quite reasonable to class electricity as a natural monopoly. What's less reasonable is regulatory capture. Landline telephones were insanely reliable in their heyday because they were required to be so. PG&E is reckless because they're allowed to be reckless.
Edit: For non-Americans, landline telephones were highly regulated up until '82 with AT&T having a government sanctioned monopoly.

Sure, and I would be lying if the libertarian bacon-wrapping of what I said was more than an litmus test and karma play, but the concept of good governance on a company like PG&E is so far out of the realm of possibility since citizen's united (and the public warping of perspective to agree with it) I don't see a very reasonable path forward to getting these (lovely, sweet, pure-hearted, well-meaning, community-oriented, positive, hard-working) people under control.

Rather than get another utility involved, I'd rather see far more incentives for installing home storage and ideally solar as well, especially for rental properties. Nothing's more resilient than a distributed grid.

One-off incidents don't really mean anything in the big picture.
However, I do recall back when there were grid problems in Texas a few years ago someone justifying the high prices California paid as due to their high grid reliability and solid regulatory framework (California pay 2x as much IIRC). I'm too far away to really get into the details but it'd be much more interesting to have a comparison on the reliability of the Californian grid compared to other US states and even countries. When it comes to high availability the diminishing returns to spending set in pretty quick and I get the impression there is a slow return to economic reality happening as voters are forcing governments to start paying attention to energy again, environmentalists or otherwise.

That claim would be hilarious and also wildly inaccurate, that OP apparently never heard of a PSPS. California’s grid is not particularly resilient or reliable, and certainly not in the 2016-2020 time frame. Also, the regulatory framework is awful and high prices are driven by a mix of 1- regulatory capture and disincentives to utilities saving money, 2- wildfire mitigation costs, 3- NIMBYism and the lack of ability to build anything quickly, and then a hodge podge of CA specific issues.
One of those specific issues is that California electricity prices include what amounts to a redistributive tax, in the form of programs like CARE and FERA - probably about a third of households in the state are eligible for CARE which provides a 30% or more discount on normal prices. While there are low-income discount programs for other states none of them have nearly the reach of the CA programs.
I find it amazing that even with the redistribution subsidy, the resulting electricity is still more expensive than the national average unsubsidized rate. We are just so incredibly good at vaporizing money.
Have been in California for 10+ years and I've never seen anyone describing California's electricity infra as reliable. It shows the same kind of failure that's too familiar to many Americans: a vital service is managed by a corporation that has no incentive for better services, and market forces do not work due to the nature of the service. (If the power at your home in SF goes out all the time, it's not like you can find another provider - the best you can do is move to, say, Nevada, which is not realistic for most people.)
I lived in California until 2018; I think I missed the beginning of the premptive outages during high winds/fire danger, but the grid sections I lived in were much more reliable where I live now, near Seattle with PSE as the utility power supplier. I was also out of CA in the post-Enron rolling blackout era.
The PNW has a more challenging environment with respect to trees pulling down lines than suburban California; I expect two nines of utility power availability here; some years will get three nines. When I was in California, many years had no outages and I don't remember any years where I had less than 99.9% availability. Even when I did eventually decide to get a UPS, it was just because one day there were several brief interruptions.
Obviously, local conditions vary, and I managed to avoid the two recent periods of larger scale grid instability, but at least in my bubble, nobody talked about grid reliability, because it was just there. Plenty of complaints about rates and how long it would take to get service changes.

marketing is marketing
all electricity economics in california is highly manipulated via regulatory capture.
PG&E pays 3-4 cents/kwh wholesale and marks it up 10x because...
it can.
however marketing has "reasons" for this... like "building hte infrastructure for electric vehicles" or "adding reliability that prevents forest fires" or ...
none of that justifies the cost.
seriously, people charging their EVs are paying for the power. Shouldn't this be how PG&E makes money, instead of some exponentially increasing rate table?
it is interesting how people pay reasonable rates in Santa Clara or Palo Alto, which have non-pg&e power companies.

The same substation went up about a decade ago, I'd be pretty cautious about calling problems with PG&E infrastructure "one off".
California's rates were rationalized, in part, because California is taking steps to increase reliability. It's been decades seen we've seen rolling blackouts at the hands of Enron. Long-term plans to increase intra-state transmission capacity are in place and are currently being executed (you're welcome to dig them up on the ISO's site). The weather related preemptive power cuts have been pared back dramatically since their introduction. We're talking hundreds of thousands of people without power for days versus hundreds or thousands for hours.
Let's not forget that the "grid problems" you're referring to cost some ratepayers tens of thousands of dollars because that's the sort of retail electric plan that was legal in Texas.
But also please don't lump all Californians one group. PG&E rate payers are extorted for some of the highest electric rates in the nation (as are SDG&E and most IOU rate payers). Folks with access to municipal power in California pay far less.

TIL traffic lights in SF don’t have a backup power flash red mode.
is that what flashing red indicates? I thought it might be that signalling is broken, possibly centralized.
It indicates an intersection fault. I've seen it happen in front of me in Texas when lightning struck too close to the cabinet.
sometimes it just means it’s too late at night to worry about traffic lights so just treat it like a stop sign.
What is the story on leveraging natural gas infrastructure in SF? In parts of Texas we've made the grid a non-issue with lots of standby natural gas generation. About 80% of the homes in my community have full backup. Wednesdays get pretty noisy at noon around here. All of the public utilities can go for days without grid power now. The winter storm was the last time anyone saw difficulties with gas infrastructure. I don't know of anyone who lost gas service, even during the event. In the TX hill country and in more rural areas, these things run on buried propane tanks and in most cases there is enough fuel on site to run continuously for weeks before a truck has to show up.
I think there is something to be said for a semi-reliable grid encouraging resilience over time. You can't have it too unreliable, but it seems like there is a sweet spot that encourages high quality contingencies to develop.

It's a shame that, during the sunniest part of the day, grid supply is supplemented by burning fossil fuels, rather than just using the energy from that sun.

Yes, apparently it is some kind of unofficial standard in the area.
Not that it will necessarily make for fewer blackouts, but a ~50% rate discount would be nice. That's what users in Santa Clara pay IIRC, and SF even owns the hydro generator at O'Shaughnessy Dam.
