Spain and Portugal hit by massive power outage causing blackouts
https://www.theguardian.com/world/2025/apr/28/spain-portugal-power-outage
Spain and Portugal have been hit by a massive power outage that has caused blackouts, Spains electricity network operator has said.
The Spanish grid operator Red Eléctrica said it had activated plans to restore the supply, with all resources dedicated to solving the disruption.
It said the Iberian peninsula, with a combined population of more than 50 million people, had been affected.
Spains public broadcaster RTVE said the outage had hit several regions of the country at about 12.30pm local time, leaving its newsroom, Spains parliament in Madrid and metro stations across the country in the dark.

(103,524 posts)that keep them going a short while - with emergency phone numbers mostly going through them now, I imagine there may be requirements for that. It also wouldn't surprise me that they might have to restrict data if it uses more power and they don't know when mains power will be restored.

(283,592 posts)Spanish power distributor Red Eléctrica said that restoring power to large parts of the country after a massive and unprecedented outage Monday that also hit Portugal could take 6-10 hours.
The company declined to speculate on the causes of the blackout. The Portuguese National Cybersecurity Center issued a statement saying there was no sign the outage was due to a cyberattack.
Eduardo Prieto, head of operations at Red Electrica, told journalists it was unprecedented, calling the event exceptional and extraordinary.
The outage hit across Spain and Portugal, including their capitals, knocking out subway networks, phone lines, traffic lights and ATM machines.
Andorra and parts of France were also hit - although the Balearic and Canary Islands seem not to have been affected

Nuno is in Guimarães in Portugal and reports that emergency shoppers crowd the few supermarkets with generators at lunchtime as parents pick students from closed schools.
Sebastian messaged me from Porto, Portugal, saying everyone is walking around with nothing to do, as he worries about problems with payments and shop supplies.
I am locked out of my apartment as the building has electronic key, que for cash (of the few ATMs working) are long with many people taking out significant sums, he says.

It is, at least, a nice day - sunny, temperature in the 70s Fahrenheit.

Hope they get the power back on, real soon. Life doesnt require electric power, but civilization does.

(283,592 posts)REN said: Due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in the very high voltage lines (400 kV), a phenomenon known as induced atmospheric vibration. These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network.
The risks posed to electrical systems by big variations in atmospheric temperatures are well known in the industry, even if it is rare for problems to manifest on this scale.

(57,868 posts)Not only the trains and airports. Street lamps, all forms of electronic payment (except where generators kicked in).
This is one of the reasons my wife and I are totally against the so-called "cashless society." Not just because every single aspect of your life can be tracked by a control freak government (think Trump, or the formerly socialist countries of Eastern Europe), but also because it leaves those who depend on electronic cash completely are at the mercy of incidents like this.
A couple of years ago, we were in a small grocery store in a small town on Cape Cod, MA, and their electronic card processing system broke down. There was a young mother in line wanting to buy $5 worth of feeding formula for her baby. She only had a card, no cash. Upon being told at the cashier that she needed to pay cash, she broke down in tears because she didn't even have $5 in cash. My wife stepped in and gave her the $5, also giving her a German-accented earful of that she thought of being 100% dependent on cards for money. The woman wanted our address to repay my wife who said, "don't be ridiculous, it will cost you more than $5 to send $5 to Germany." My wife said the woman could repay her by never again going out with so little cash on her that this could ever happen. Considering how traumatized she seemed, she might just have done it.
I hope no such situations occurred down in Iberia, but they are really into cards down there, too, and I'll bet that plenty of people were caught off-guard, although the people there are (in general) very friendly, and willing to help out people in need.
We really hope this was caused by extreme environmental conditions, because if this was a coordinated attack, and was a dry run for similar action on northern Europe, it showed how vulnerable a huge area can be to being shut down in an instant.

(283,592 posts)Power is coming back in the Spanish capital, some shops and the metro. Some rural areas are reporting the power being restored.
Public transport, the trains and metro are still not open to the public but security is gathering at the entrance of Sol metro station for it to be opened soon.
Rural areas north of Madrid have reported the power and Wifi coming back.

(103,524 posts)The risks posed to electrical systems by big variations in atmospheric temperatures are well known in the industry, even if it is rare for problems to manifest on this scale.
Due to the variation of the temperature, the parameters of the conductor change slightly, said Taco Engelaar, managing director at Neara, a software provider to energy utilities. It creates an imbalance in the frequency.
Georg Zachmann, a senior fellow at Bruegel, a Brussels thinktank, saidthe system had suffered cascading disconnections of power plants including one in France when the frequency of the grid dropped below the European standard of 50Hz.

Though I'm not entirely convinced about these "big variations in atmospheric temperatures":
In recent days temperatures have hit 30c in Sevilla and 25c in Madrid.
https://www.manchestereveningnews.co.uk/news/world-news/rare-atmospheric-phenomenon-behind-huge-31527467
Warm for the time of year, but not for summer, and if the conditions are "across the country", then there isn't a big regional variation.
Or maybe the France-Spain interconnection - whether that's "induced atmospheric vibration" too, I can't tell:
Spanish grid operator REE's system operations chief Eduardo Prieto told La Vanguardia that the interconnection failure, which occurred at just after 12.30 p.m. local time, was responsible for the outage that affected most of the Iberian Peninsula on Monday.

(103,524 posts)but all I can find looks like handwaving so far. Some scepticism here:
https://physics.stackexchange.com/questions/848666/what-is-induced-atmospheric-vibration
One answer points to a paper "Diagnosis and Mitigation of Observed Oscillations in IBR-Dominant Power Systems" ('IBR' is "inverter-based resources" "such as solar photovoltaics, wind, and battery systems and inverter-based transmission, distribution, and load technologies" ), but that barely mentions temperature (just about the temperature of capacitors, a couple of times - nothing about weather).
This news report also seems sceptical:
...
We saw that after a massive electrical storm in Australia in 2016 when there were 80,000 lightning strikes.
The weather in Spain on Monday was calm and sunny with average spring temperatures.
According to an expert I spoke to, it would be really really weird for this weather to have caused - or 'induced atmospheric vibrations.
https://www.itv.com/news/2025-04-28/oscillations-and-vibrations-what-caused-the-power-outage-in-spain-and-portugal
Or maybe it was lost in translation, or in explaining to a non-technical person:
REN later refuted these claims in the Portuguese media. But what are these vibrations, and what effect would they have had on the regions power grid?
Solomon Brown, a professor of process and energy systems at the University of Sheffield in the UK, said that an "induced atmospheric vibration" could be considered the equivalent of "inducing a small shift in the local electromagnetic field".
