> Berlin got a blackout once in a decade like most American cities get multiple times a year.
The Berlin power outage linked above was over thirty hours, and the SF outages you linked were a few hours. To bury that in "(not always duration)" seems misleading to me. That said, the 2019 power cuts were indeed approaching third-world duration and frequency, to the point that homeowners who could afford it applied the usual third-world workarounds (gas generators, etc.). That was mostly outside the biggest cities, but huge numbers of people were affected.
And how did we get from SF to "most American cities"? California's grid reliability is notoriously and distinctively bad, and a huge political topic here too (though with little progress after many years). The World Bank[1] puts the overall USA's quality of electricity supply solidly in the middle of high-income countries though, slightly ahead of Germany.
We also seem to be mixing load shedding (i.e., the utility realizes they can't safely supply all their customers and therefore deliberately cuts power to some) with accidental outages. They look the same to the customer, but perhaps imply different kinds of bad planning by the utility.

All of these affected many more (Chicago: 800K), occur rather frequently and seem to be caused by regular phenomena like weather. One major reason is that so much of power-distribution is above-ground, on these poles you see everywhere. Storms will knock these over or have falling trees take them down. >We also seem to be mixing load shedding ... with accidental outages. Yes. The claim was that "most 1st world countries" experience rolling blackouts. That's not true.
- tripletao 6y agoTo be clear, I agree that most developed countries don't routinely experience rolling blackouts like the one that just happened in California. This includes the USA, unless we count twice in twenty years in the state with the worst grid as "routinely". I don't think it's useful to compare anecdotes, though I'd note again that most of the outages linked above are far shorter than the Berlin outage. Anyone who believes that most American cities experience multiple thirty-hour, 30k-customer outages per year (as the comment I first replied to implied, despite the hedge with "not always duration") is mistaken. morelisp's later comment linked to SAIDI numbers for the USA and Germany, and by that standard[1] Germany is indeed far better than the USA, about 4.5 nines to our 3.5. Singapore[2] is yet better, about 6 nines. The USA is far worse than the EU average, somewhere around Italian[3] standards. That's an undeniable difference, though I'm not sure all of that is attributable to incompetent American operators (though certainly some is, as PG&E has repeatedly shown). The grid can't target perfect reliability, since the cost for that would exceed the benefit in almost all applications. It's cheaper to provide backup power for the few exceptions (data centers, medical, etc.). The cost per customer to achieve a certain reliability will be higher with lower population density. The cost for backup power is fixed. So the economically efficient grid reliability should be worse with lower population density, which seems to be what we see empirically--Australia is bad too, for example. I'd guess that much of the difference is simply because the USA has decided that Germany-level reliability isn't cost-effective, in the same way that Germany has decided that Singapore-level reliability isn't cost-effective. I'd guess the World Bank ranking I cited somehow tries to capture that fact and therefore ranks all three countries about the same, though I can't find any details of their methodology. 1. https://spectrum.ieee.org/energywise/energy/the-smarter-grid/germanys-superstable-solarsoaked-grid https://spectrum.ieee.org/energywise/energy/the-smarter-grid... 2. https://www.ema.gov.sg/cmsmedia/Publications_and_Statistics/Publications/EMA%20AR%202016_17.pdf https://www.ema.gov.sg/cmsmedia/Publications_and_Statistics/... 3. https://www.occto.or.jp/en/information_disclosure/miscellaneous/files/181221_qualityofelectoricity_2017.pdf https://www.occto.or.jp/en/information_disclosure/miscellane... , Tables 45 and 46
- mpweiher 6y agoWhat do you mean "twice in 20 years"? 2019: "California’s largest utility is under severe scrutiny by state regulators and customers over its rolling blackouts that have left millions of people without power. Just two weeks after a massive power shut-off that the company acknowledged it mishandled, Pacific Gas & Electric announced on Wednesday that it will cut electricity to 179,000 customers in California in the face of a new wildfire threat. Southern California Edison, the state’s second-largest investor-owned utility, also warned on Wednesday of power outages to 308,000 customers." https://www.cnbc.com/2019/10/23/pge-rebuked-over-imposing-blackouts-in-california-to-reduce-fire-risk.html https://www.cnbc.com/2019/10/23/pge-rebuked-over-imposing-bl... That's at least 1 and possibly 3 power cutoffs (not outages, deliberate cuts) just in 2019. Several days so far in 2020, with millions affected. https://www.vox.com/2020/8/15/21370128/california-blackouts-rolling-power-outage https://www.vox.com/2020/8/15/21370128/california-blackouts-... And the year is still young. And of course the energy crisis in 2000-2001 caused many, many blackouts over the course of two years, it's not the single incident you are implying. https://en.wikipedia.org/wiki/California_electricity_crisis https://en.wikipedia.org/wiki/California_electricity_crisis > far shorter than the Berlin outage Shifting goal posts. This was a single outage affecting 30K people. Just the one Chicago outage affected 800K people, that's 26x more people. This isn't comparing Apples and Oranges, this is comparing Apples and Aircraft Carriers. And most of the others are over 100K people. And there are multiple ones per city. Per year. And I stopped looking after it was clear that many cities were affected by much larger outages multiple times a year. My guess is that outages affecting only 30K people just didn't make the news. > The grid can't target perfect reliability Yes, being resilient against construction workers cutting the cable is difficult. However, being resilient against storms, storms that occur just about every year should be something you can expect, and in non-third-world countries is something that you actually can expect. That doesn't mean there never is storm damage, just that power isn't routinely cut when there's a storm as seems to be the case. Or when the weather is hot. Austria has much worse snow storms and ice than what we saw that winter in Detroit, every year. And avalanches. Yet I've never seen or experienced anything like that power outage. And it doesn't look like anything substantial has changed. The US has been under-investing in infrastructure for many decades, and it shows. If you don't believe it, visit other places. > reliability will be higher with lower population density New York has a low population density? Chicago? The Bay Area?
- morelisp 6y ago> We also seem to be mixing load shedding... with accidental outages. Not 'we'; I'm well-aware of the difference but the person I was responding to gave examples of accidental outages. The US has considerably more of both than Europe, especially Germany (SAIDI measured in hours vs. 15-20 minutes), regardless of what investment-focused metrics the World Bank is giving.
