Power Outage in Spain – An Analysis

Solar energy comes out of your panels as direct current (DC). That’s all well and good, but homes and grids run on alternating current (AC). Enter the inverter – the humble box that turns solar wizardry into household juice.

Now, inverters aren’t just fancy plug adapters. They have to sync up with the grid – which means they generate exactly the same frequency as the rest of the system. No grid? No syncing. In that case, the inverter goes into what’s called island mode and produces power only for local use. So, if my solar system isn’t connected to the external grid, it can’t run the house – but it can still power two little emergency sockets. Cheers, I guess.

Normally, the grid runs at 50 Hz – that’s hertz, not some obscure Scandinavian metal band. But this frequency can wobble a bit. Physically and technically speaking, it rises when there’s too much power and not enough consumption, and falls when there’s a hungry grid and not enough electricity to feed it.

To keep the grid safe, inverters have an emergency shutdown feature: if the frequency goes over a set limit (apparently around 50.2 Hz), they also jump ship and go into island mode.

Spain’s energy mix is a bit unusual: lots of nuclear, lots of renewables – and a large chunk of those renewables are solar. Makes perfect sense in a country where “cloudy” means three fluffy cotton balls drifted by.

Now, nuclear energy comes with two charming quirks. First, you can’t change its output quickly – it’s not a dimmer switch, more like a cruise ship rudder. Second, nuclear plants cost nearly the same to run at half speed as they do at full throttle. So, naturally, you want to keep them purring along at max capacity.

Then came Monday, with weather conditions perfect enough to make a solar engineer weep with joy: loads of sun, plenty of wind. By 9 a.m., Spain’s energy needs were entirely met by nuclear and renewables. In fact, they had surplus electricity and began exporting it by the bucketload. They shut down everything easy to shut down – but nuclear? No chance. It stayed full steam ahead.

Then, two unfortunate things happened: one transmission line to France caught fire (as you do), and another developed resonances due to meteorological oddities.

So far, this is all well documented. Now we step into speculation territory.

These instabilities meant Spain couldn’t get rid of its excess electricity. The grid frequency rose past that critical 50.2 Hz mark – and boom: many solar systems switched to island mode. At that moment, they were providing nearly 15 gigawatts – around 60% of the national supply. And just like that, poof – they were gone.

Suddenly, two-thirds of the electricity vanished. Wind, nukes, and batteries couldn’t keep up – quite the opposite, in fact. To prevent damage, the nuclear plants initiated emergency shutdowns. Not great. (More on why that’s bad in a bit.) Within seconds, the entire grid collapsed. The solar systems were poised to help – but there was no grid left to sync with.

Everything went dark.

Portugal and southern France were also knocked offline, as they’d been happily sipping from Spain’s excess power. The European grid wasn’t amused and unceremoniously kicked Spain out of the club. France, with a bit of backup and a stiff upper lip, restored its network fairly quickly. My home automation system even picked up the moment the frequency dipped and France cranked up its own generation.

Portugal got the rough end of the stick. With fewer reserves and being smaller in size, they couldn’t help themselves – and no one else could help either, since Spain’s their only neighbour.

Rebooting the Grid – Why It’s a Right Pain

Restarting a collapsed grid isn’t just a matter of flipping a giant switch. It’s tricky for two reasons:

  • Generation and consumption have to be in perfect balance. If not, we’re back to square one.
  • Nuclear power plants can’t just be turned back on. After an emergency shutdown, they suffer from something called xenon poisoning (yes, one of the very same issues that made Chernobyl a household name). You’ve got to wait for that to wear off – which means the reactors were still offline two days later.

The fix? You split the grid into smaller bits. For each chunk, you build up some capacity, bring it online, then move on to the next. Rinse and repeat. This takes hours. Meanwhile, the sun moves across the sky – and even if you do reconnect the solar arrays, they won’t produce nearly as much as before. Come 8 p.m., they’re more or less useless.

So Spain needed outside help. They were gradually reconnected to the European grid – in small, careful steps. Without that assistance, large parts of Spain would probably still be in the dark. That’s why electricity came back first in places like Barcelona, close to the French border, while Portugal endured the longest wait.

Notes & Musings

  • Considering the scale of the event, the recovery was impressively quick. In San Sebastian, power was back within 2 hours. (For comparison: Wismar in Germany had a 45-minute outage last year because one substation had a wobble.) Portugal got its power back after 23 hours. I had expected one to two days.
  • This was the largest blackout in Europe in 40 years. If, as suspected, climate-related factors helped spark (pun intended) the situation, then modernising the grid to better handle volatility is absolutely essential. That includes implementing the long-debated power zones in Germany.

Tällä hetkellä työstän samanaikaisesti runokirjaa ja sarjakuvakirjaa. Saattaa kuulostaa tuskaisalta, mutta minulle sopii useamman projektin tekeminen rinnakkain.

Olen pohtinut tätä tekemisen tapaa ja huomannut, että usein kokonaisuus toimii, kun tekstilajit ovat keskenään erilaisia. Esimerkiksi kahden runousprojektin samanaikainen tekeminen ei välttämättä onnistuisi.

Tämän tekstilajien välillä vaihtelun hyödyllisyyden (itselleni, ei toimi kaikilla) huomaa erityisesti nyt, kun päätyöni on tutkimusta. Rakastan akateemisen tekstin kirjoittamista, mutta siihen syventymisen jälkeen on vaihdettava johonkin virtaavampaan. Esimerkiksi sarjakuvan käsikirjoittaminen tai runo on totisesti tervetullut siirtymä tutkimuskysymyksen viilauksen ja lähdeluettelon tarkastelun jälkeen.

Olisi kiva keskustella muiden kirjoittajien kanssa, minkälaisia yhdistelmiä teillä on.

Yksi projekti kerrallaan, kaksi rinnakkain kulkevaa juttua, vai kenties joku sekalaisempi setti?

Hello, #Mastodon!

I’m Katie Livingstone, an American journalist based in #Ukraine who has been covering the war since 2022. My work has appeared in Rolling Stone, Business Insider, USA Today, Newsweek, ForeignPolicy, Military.com, and several other outlets.

Harry Potter fans tend to argue for the seperation of art from the artist.

That's a maybe.

But unlike, say, Lovecraft, your money is going to an alive person that is trying to eradicate my people *using* that money.

I wouldn't be able to look myself in the mirror if I did that to any minority.

I'm completely at a loss for words to express how disgusting it is that the grifter D.J. Trump has forced Ukraine to sign this extortionate "deal".

I can't think of a single other example of a country giving financial and military aid to an ally at war, and then suddenly deciding that their aid was actually loans and demanding them back - while the war is still going on.

Ridiculous, petty villainy on a grand strategic scale. What a time we live in. https://www.theguardian.com/us-news/2025/apr/30/us-ukraine-minerals-deal-russia

Among other things, Meta is now making it mandatory to store voice recordings from their Rayban "smart" glasses in the Meta cloud, and making Meta AI's ability to train and see through your lenses "always on" unless you disable it each time manually.

Gonna be honest, any time someone with Raybans talks to me, I'm going to ask them to remove the glasses.

@BenRiceM @mathowie Ben, I think you are too young to have seen the Gillian Islands episode where they have logs on the beach to spell SOS but Gillian trips and makes it SOL who happens to be the name of the pilot who is flying the plane and thinks it is just a nice gesture.
@mathowie Bluebonnet?! What a nice name for such a horrible place. Trump just needs to change “detention facility” to “Summer Camp” to make everyone feel better about it, right?!
@GoofNewf @mathowie
It's appropriate because it's the state flower of this fascist place and its a good reminder that we are complicit in this. If we can make people associate bluebonnets with authoritarianism, good. This whole state was stolen to enable the slave trade to continue. Once the US banned importing new slaves, they just trafficked them through independent Texas instead. These were our so-called state founding fathers too, their names and likeness all over the place. Fuck the Alamo!
@heymarkreeves @mathowie
I appreciate you sharing the source.
Please, I beg of everyone out there trying their best to expose the depravity and dishonesty of the current US administration to make sure that others don't need to dig for the source of your claims.
@mathowie If we had a German government and a German public that really took the responsibility of history seriously, we would have to start cutting relations with the USA now, kick all the troops out of the country and summon the ambassadors or kick them out of the country too. Never again fascism! But this country is not interested in that.

@wackJackle @mathowie

Given that Vance was booed when he visited the troops in Rammstein, I think that European governments should consider offering all US-Americans currently here the possibility of just staying here with their families before the US withdraws its troops.

@mathowie That tells you everything you need to know.

@mathowie That SOS photo will define Trump like Abu Ghraib defines W.
Shameful.

It's obvious that the GOP does not, in fact, hold these truths to be self-evident.

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

@mathowie Didn't take but a hundred days before we're undeniably wallowing in the swill and the filth and the shame of it. Guess we were nearly there to begin with already huh?

@mathowie Way to go #fauxgressive #BernieSanders protest voting, non-voting, "I don't like my choices" #GreenParty TRASH.
All of this shit was avoidable.

@arbres

Hi Arbres, your frustration is very understandable, but I have few comments:

1. This isn't helpful. It's too late. We need these people as allies now, so it's actively counterproductive.
2. Shouting accusations randomly is maybe also a bit unhelpful.
3. Trump voters bear a tiny portion of the blame, surely?

@celesteh @arbres

Took the words right out of my mouth.

@alisynthesis @celesteh And fuck both of you.
We don't need these shitty failures as humans as "allies".
Not helpful?
Fuck you some more.

@alisynthesis

Its so weird blaming Sanders who wasn't running in 2024 and also seems to be one of the only Democrats actually doing anything meaningful.

Very sus. Anyway this is a problem sorted by the block button.

@arbres message from outside: the USAian general public will survive the regime better if it doesn't eat itself. Go meet a neighbour. That's who is going to hide and feed you.
@arbres @mathowie
No, it's the Democratic party's fault for trying to seduce Trump voters instead of supporting human rights and the rule of law. Biden deported a lot more people than Trump did, he just didn't brag about it and kept it out of the news. Biden dumped billions into the genocide in Palestine and Harris would have continued it exactly like Trump is. Dems v GOP = Dog Shit Sandwich v Cat Shit Sandwich. "lesser of two evils" is still evil. Trump won because his base is proudly evil.

@arbres

This is a remarkable take. Why not blame e.g. the people who actively voted for 47, the media who made 47 seem electable, Biden & Harris for abetting war crimes in Gaza (or all the other choices that contributed to people not wanting to vote for them), the people who failed to disqualify 47, or even - consider it - the people actually doing the human rights abuses now?

@unchartedworlds FUCK OFF. Biden and Harris DID NOT AID OR ABET SHIT YOU FUCKING MORON.

Jesus Christ all of you halfwits, have a day off.

“God did the State of Israel a favor that Biden was the president during this period, because it could have been much worse. We fought [in Gaza] for over a year and the administration never came to us and said, ‘ceasefire now.’ It never did. And that’s not to be taken for granted”

@arbres THE BIDEN ADMINISTRATION AIDED AND ABETTED A GENOCIDE, YOU FOOL

@arbres everything you have said in this thread is extreme right wing rhetoric (othering of your own people, ableist slurs, aggressive dismissal of any opposition to your favoured political party from your peers). You are in no way hiding that you are doing this.

It's unusual that you are claiming not to be in support of the newly installed extreme right regime in your country. Care to explain? Your position is not coming across as believable.

Given that the " @arbres " account has randomly popped up on an unrelated viral thread talking very aggressively about their own politics, I suggest some caution is in order.

It looks to me like a trump supporter trying to make liberal opposition look bad and ridiculous, while also inserting trumpist rhetoric into discussion.

@mathowie 🎶 For Trump we voted now we’ll be deported, SOS. You think it’s just us? You’ll be on the next bus, SOS 🎶
