西班牙和葡萄牙遭遇大范围停电,法国和意大利部分地区也据报道受到影响。停电导致所有系统立即瘫痪,恢复供电时间尚不明确。 民众正在使用移动互联网进行沟通,移动网络依靠电信运营商的备用电源(电池和柴油发电机)运行。尽管停电,一些活动,例如街头游行仍在继续。关于停电原因的猜测从电网超负荷到更阴险的可能性,例如EMP攻击、俄罗斯甚至外星人,不一而足。然而,局部电网超负荷导致级联故障似乎是最合理的解释。 CNN、天空新闻、BBC和RTE等新闻媒体正在报道此事,并在线分享实时更新。虽然预计将进行全面调查,但此次事件凸显了互联电网的基础设施风险以及效率和弹性之间的权衡。交通信号灯熄灭,当局建议民众为安全起见待在家中。停电还影响了安道尔,受影响国家总数达到三个。

Full power outage in Spain and Portugal
175 points by lleims 39 minutes ago | hide | past | favorite | 49 comments
All of Spain is without energy. All systems have shut down immediately and are not coming back. Apparently the same has happened in Portugal.










Hello from Portugal. Local news is indeed reporting that power is out across all of Iberia.


I'm in Valencia and it is indeed happening here. A street parade under my windows continues nonetheless.


How are you posting this?


Telcos have tons of backup power. They’re required to have it.


Mobile internet still works.


Cell towers have backup generators?


Most of them have batteries. How long they last depends, in my country they can typically manage 4 hours.


Batteries at least.


They still need other infrastructure to get anywhere though (routers and other networking infrastructure).




Tuscany good so far

Edit

However, I can't get the energy provided outage map to load, maybe too many people accessing it



People are not voting this up to top because they're offline. This outage is quite massive.




Parts of France are also affected according to Sky:

France and Italy. Aliens? Russia? EMP?


There's a connected grid across most of continental europe. If Portugal's grid blacked out unexpectedly then Spain's grid could have been made unstable too, which then continue onwards to South of France and Italy.

Just a typical cascade failure because it means everything's now running with lower tolerances.



Neither. Apparently a local grid overload and a cascading failure, but radio and newspapers don’t agree on root cause.


EMP would kill electronics no?


Portugal has no electricity as we speak. Funny enough telcos and 4G/5G are fine for now, I'm guessing batteries and diesel backups kicked in and are doing their job.


Yeah, we just told you that via Signal - that’s how we built the networks :)

(No relation to the other infamous Signal chat :))

There should be 4-8 hours of battery backup on every site - at least.



Here's a "real time" map of electricity production and flow between countries: https://app.electricitymaps.com/map/72h/hourly

Would be interesting to see if it will register here.



It should take 72 hours to update


I think that must be the scale so you can browse the historical data. The resolution on the slider is 1H when on 72H scale.


Looking forward to the postmortem


Definitely looking forward to this postmortem.


How can we follow this story? Who's updating in real time?


How long before the Estonian led EU start blaming Russia ?


Russian pincer move?


What beef does russia have against spain and portugal?


Parts of EU.


Ok...? Is there like more to this narrative or are we supposed to buy that russia just hates all of europe for being europe now? Whatever happened to the "rational actor" canard?


or North Korean


i had an appointment in Barcelona, but can only guess it’s not safe on the roads


Traffic lights are out across Iberia apparently, better stay home.




A full nationwide power outage affecting not one but three [0] countries.

Sounds like a major infrastructure risk given that it is possible for more than one country to experience a full loss of power.

EDIT: Andorra is also affected, so that is three.

The European grid is a connected synchronous grid. Usually that would add stability but it also means if a single country's grid blacks out then their neighbours have to respond to that. Portugal and Spain's grids will be intimately connected which won't have helped.

Not something that's easy to test for.



The whole European grid is essentially connected at this point, it's a simple trade of resiliency for efficiency. People just forget about the resiliency part until something goes wrong


Yes, it’s happening


barcelona has been out for the past 20 minutes or so


Yep. No signs of any invasion, though. But cue the conspiracy theories.


Spain and Portugal are quite big and with harsh terrain, I doubt anyone would bother invading in a traditional sense.


Who would even invade Spain and Portugal? E.T?


Well, we love all kinds of tourists. Why not ones that could change the world? :)

#irony



Morocco might (again).


Got reports from Toledo and Madrid


I can confirm (I'm from Portugal)


Source?


I can confirm, all coworkers from Portugal seem to be affected. Big thing.
