If an entire nation trips offline then every generator station disconnects itself from the grid and the grid itself snaps apart into islands. To bring it back you have to disconnect consumer loads and then re-energize a small set of plants that have dedicated black start capability. Thermal plants require energy to start up and renewables require external sources of inertia for frequency stabilization, so this usually requires turning on a small diesel generator that creates enough power to bootstrap a bigger generator and so on up until there's enough electricity to start the plant itself. With that back online the power from it can be used to re-energize other plants that lack black start capability in a chain until you have a series of isolated islands. Those islands then have to be synchronized and reconnected, whilst simultaneously bringing load online in large blocks.
The whole thing is planned for, but you can't really rehearse for it. During a black start the grid is highly unstable. If something goes wrong then it can trip out again during the restart, sending you back to the beginning. It's especially likely if the original blackout caused undetected equipment damage, or if it was caused by such damage.
In the UK contingency planning assumes a black start could take up to 72 hours, although if things go well it would be faster. It's one reason it's a good idea to always have some cash at home.
Edit: There's a press release about a 2016 black start drill in Spain/Portugal here: https://www.ree.es/en/press-office/press-release/2016/11/spa...
A full grid black start is orders of magnitude more complex. You’re not just reviving one machine — you’re trying to bring back entire islands of infrastructure, synchronize them perfectly, and pray nothing trips out along the way. Watching a rig wake up is impressive. Restarting a whole country’s grid is heroic.
A rare but sobering opportunity to reflect on something we usually take for granted: electricity.
We live in societies where everything depends on the grid — from logistics and healthcare to communications and financial systems. And yet, public awareness of the infrastructure behind it is shockingly low. We tend to notice the power grid only when it breaks.
We’ve neglected it for decades. In many regions, burying power lines is dismissed as “too expensive.” But compare that cost to the consequences of grid collapse in extreme weather, cyberattacks, or even solar storms — the stakes are existential. High-impact, low-frequency events are easy to ignore until they’re not.
Also I suspect there is far more renewables on the grid now than in 2016.
This is potentially the first real black start of a grid with high renewable (solar/wind) penetration that I am aware of. Black starts with grids like this I imagine are much more technically challenging because you have generation coming on the grid (or not coming on) that you don't expect and you have to hope all the equipment is working correctly on "(semi)-distributed" generation assets which probably don't have the same level of technical oversight that a major gas/coal/nuclear/hydro plant does.
I put in another comment about the 2019 outage which was happened because a trip on a 400kV line caused a giant offshore wind farm to trip because its voltage regulator detected a problem it shouldn't have tripped the entire wind output over.
Eg: if you are doing a black start and then suddenly a bunch of smallish ~10MW solar farms start producing and feeding back in "automatically", you could then cause another trip because there isn't enough load for that. Same with rooftop solar.
Does this really qualify as "black start" when they can rely on the bigger EU grid?
It's far more problematic for the UK because all the interconnects are DC.
If your Factory uses too much power, theres not enough energy to run the power plants generation, which decreases your power production. Death spiraling until theres no power.
You have to disconnect the factory, and independently power your power plants back up until you have enough energy production to connect your factory up again.
- Cause of event not known yet.
- They noticed power oscillations from the Spanish grid that tripped safety mechanisms in the Portuguese grid. At the time, due to the cheaper prices, the Portuguese grid was in a state of importing electricity from Spain.
- They are bringing up multiple power systems and the Portuguese grid is able to supply 100% of needs if required. It was not configured in such a state at the moment of event.
- They had to restart the black start more than once, since while starting, noticed instabilities in some sectors that forced them to restart the process.
- Time for full recovery unknown at this time, but it will take at least 24 hours.
Would this suggest the grid hasn't snapped apart, or is it just not possible to tell from the data?
Coal, pumped hydro, and nuclear generation all went to 0 around the same time, but presumably that's those sources being disconnected from the grid to balance demand? https://transparency.entsoe.eu/generation/r2/actualGeneratio...
It's not just about the power. System components cannot be brought to operating temperatures, speeds and pressures faster than mechanical tolerances allow. If a thermal plant is cold & dark, it can take days to ramp it to full production.
1. The grid has to fully collapse with no possibility of being rescued by interconnection
2. As a result, a generation asset has to be started without external power or a grid frequency to synch to
3. An asset capable of this is usually a small one connected to a lower voltage network that has to then backfeed the higher voltage one
4. Due to the difficulty of balancing supply/demand during the process, the frequency can fluctuate violently with a high risk of tripping the system offline again
None of this applies in yesterday's case:
The rest of the European synchronous grid is working just fine.
News reports stated Spain restored power by reconnecting to France and Morocco.
By reestablishing the HV network first, they can directly restart the largest generation asset with normal procedures.
As they bring more and more load or generation online, there's little risk of big frequency fluctuations because the wider grid can absorb that.
I can only imagine the difficulty of bringing large parts of the grid back online, that rush current must be immense.
More than cash it was important yesterday to have the following in case it would have lasted longer:
- a battery powered am/fm radio with spare new batteries
- some candles and matches
- food reserves for a few days that don't need refrigeration: bread, anything in can, pasta, rice...
- some kind of gaz or alcohol stove, dry wood or bbq charcoal: you can always make a fire in the middle of the street where there is no risk of burning things around.
- water reserve (I always have like 24L of drinking water) and since I hate waste I regularly fill jerrycans when waiting for hot water in the shower that I use for manual washes (kitchenware or gears).
But with solar, how is the synchronization provided? In like a giant buck? Or in software somehow? Does the phase shift matter as much as in the electromechanical systems?
My intuition is that solar would make the grid harder to keep stable (smaller mass spinning in sync) but also may offer more knobs to control things (big DC source that you can toggle on/off instantly.. as long as sun is out). But I don’t actually know.
"Luckily", France is at an historically high level of production capacity at the moment and the connection between the two countries was reestablished fast.
According to RTE (French network manager), the interconnection was maxed yesterday at around 3GW of power.
Sadly, while Spain is part of CESA, it's not very well connected. I wouldn't be surprised if one the takeaway from the whole incident is that more interconnections are needed.
Ukraine went through many black starts in the first winter of Russian strikes against energy. I guess they built a skill of recovering it quickly enough that it started happening faster and easier every next time.
> have some cash at home
For maybe the first 24 hours at a grocery store, and then not so sure. Would your neighbors sell you supplies and food? Maybe not? And so many places now depend on cashless transactions and doubtful they have pen, paper, lockbox, and safe as a contingency plan.
The entire EU runs on one synchronised grid so from that perspective a single 'province' went offline, not the grid.
Most places are so dependent upon electricity that they can't even take cash during a blackout. And they don't even have the mechanical machines to take a credit card imprint anymore.
There is precedent for major power outages, a huge majority of which are not malicious: https://en.wikipedia.org/wiki/List_of_major_power_outages
I remember the day when the Swiss railway power network went down for a day (in 2005) because one power line was down for maintenance and someone pressed the wrong button and produced a short circuit somewhere else. It's a bit like the incidents in planes were one engine has a problem and the crew shut down the other one by mistake.
In Texas, the electric providers cut staff and maintenance to maximize shareholder value. They will not have redundant systems and redundant plants out of the goodness of their hearts. The Texas marketplace actually allowed them in the odd event of an outage to charge astronomical spot prices thinking this will incentivize them to have redundant systems. This was a foolish fantasy.
Now in Texas, discussion of how to cost share redundancy have taken place. But no one wants to pay for it. https://www.texastribune.org/2023/03/01/texas-power-market-p...
So frequent it even has its own wikipedia page: https://en.wikipedia.org/wiki/Category:Airliner_accidents_an...
I only have a layman's understanding of power grids, but I thought they were incredibly hardened, with backups and contingencies in depth
Are the grids at this scale really this brittle? Would there be a death toll from this?
I also wouldn't blame malice without corroborating evidence
I think we should prepare for the worst though. It's wrong to assume it's not an attack too, and until we can conclude it's not an attack we should be prepared to deal with the possible consequences and act accordingly.
Very poorly explained right now by Space Weather News. I am waiting for an updated explanation.
Three quarter of the production disconnects from the grid between 12:30 and 13:00, with only a bit of solar and onshore wind sticking around.
I don't think we're able to tell from the data if one is the cause of the other, are we? Since if production was lost, load would have to be shedded to balance the grid, and if load was lost (e.g. due to a transmission failure), production would have to be disconnected to balance the grid.

For instance, one reporter asked one of the government flunkies whether it could be a cyberattack and they turned his noncommittal “maybe, we don’t know” into “government says cyberattack may be ongoing”.
Be careful of idiot reporters out there.
Edit: I’m listening to another radio interview where they are outlining the plans to bring online Portuguese dams and thermal generators over the next few hours, progressively unplugging from the Spanish supply (fortunately we have enough of those, apparently).
It should take 3-4 hours to get everything balanced with only national supplies, and they will restore power from North to South.
Key points that started it were (you can see the chain of events in the doc):
2.4.1. At 16:52:33 on Friday 9 August 2019, a lightning strike caused a fault on the Eaton Socon – Wymondley 400kV line. This is not unusual and was rectified within 80 milliseconds (ms)
2.4.2. The fault affected the local distribution networks and approximately 150MW of distributed generation disconnected from the networks or ‘tripped off’ due to a safety mechanism known as vector shift protection
2.4.3. The voltage control system at the Hornsea 1 offshore wind farm did not respond to the impact of the fault on the transmission system as expected and became unstable. Hornsea 1 rapidly reduced its power generation or ‘deloaded’ from 799MW to 62MW (a reduction of 737MW).
(apologies for singling out these specific groups of people - my point is that it might be worth to put down news sources like xitter, and read AP/translated local Portuguese news)
News travelled extremely slow: phone coverage was just barely enough to receive a couple text messages every 15 minutes or so. News spread on the street, I even saw a group of 20 people hunched around someone owning a hand-held radio in the streets.
Just before power was restored, things started to get worse, as the phone coverage went completely out (presumably batteries were depleted). People were in between enjoying the work-free day, and starting to worry about how tomorrow would look like if power didn't come back.
I stopped by a friends house and we then went on a walk. Some stores were open and cash was accepted. We hung out later that night and had a few beers. The sky was amazing as there was next to no light pollution. Next day was totally in the dark as well and again, no panic. More beers were enjoyed.
The choice to move to electronic everything without having to give a shit about reliability is a failure of modern government. Move fast and break society for a dollar.
Electricty went down (something kind of frequent). My UPS kept PC up, and alarm system with sim and small UPS mantained wifi up for an hour or so.
Scary moments started when people I was in a call with in Portugal texted 'Grid is out'. Later no phone signal nor data.
At first, it might seem people running towards supermarkets an overreaction on being without TikTok for a couple of hours, but you have to live how scary it is to experience this in Europe's current political status to know 60 million people (plus industry) in three countries are out of the grid.
If you see Snowden's film (this might not be the most trustworthy source) it is exactly how CIA's agent describes the feasable attack towards these countries. Again, not a valid source, but I'd love to understand if that could be feasable.
All gas stations closed because they could not sell gasoline/diesel. Today there are lines on all gas stations, people filling their car tanks and bottles..
Oh, let me tell you about electric cars! Many people had to spend the night somewhere away from home because they could not charge their cars.. My sister (with her job's electric car) had to stay the night some 200km away from home, and since the ATMs (Multibanco) didn't work, she didn't have physical money to pay for food. Luckily a stranger paid for the food (yogurt and some cookies). Petrol cars, because of their range, had better luck!
Pure fear and panic..
I can only blame the authorities (Portuguese/European) for not having contingency plans for keeping people informed, and thus letting fear spread like wildfire.
I wonder what similar solutions exist in the iOS ecosystem.
I lost some years today.
My son is fine, thanks to a random person (“the man with a rabbit”) who just decided to give a lift to my son and his friend to the edge of Barcelona.
I hope this comes back ASAP.
The atmosphere was quasi-festive and most people were quite relaxed, enjoying an unexpected afternoon off. Younger people filled the bars which were serving everything they could. There were long lines at supermarkets and an occasional fellow toting a box of supplies, but mostly there were just huge numbers of people in the street and completely collapsed traffic flow (the police were out in force almost immediately, directing traffic). In the part of Madrid I was in about 1/4-1/3 of the population is from South America and I suspect most of them have seen this all before anyway. The only real stress I saw was from people that need a train to get home (because the trains weren't running) and a had a walk of more than 2-3 hours.
I got cell phone signal when I was near two hospitals which were fully operational.
It was interesting that almost immediately, while I was still at work, everyone said power was out in Portugal and France too. After an hour or two some were claiming problems in Germany, but this seemed already to be unfounded rumors.
Some younger people couldn't walk home because they didn't have google maps ...
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.”

I suppose it makes sense that it was an automatic shutdown rather than infrastructure failing on such a wide area. And then once it's shut down, a black-start is a logistical challenge as other comments have explained.
I'm also seeing some reports about it being more likely that something happened on the east side, somewhere like the Ebro valley or north across the Pyrenees. Catalonia seems to have been particularly affected, and it's on the path of important lines coming from France. High heat at noon could have caused a line to fail and short against a tree, which would be similar to the 2003 nation-wide outage in Italy.
"Le gestionnaire français souligne par ailleurs que cette panne n’est pas due à un incendie dans le sud de la France, entre Narbonne et Perpignan, contrairement à des informations qui circulent."

Portugal nearly reached zero.
There's a map at [2]
> The Spanish electricity system is currently connected to the systems of France, Portugal, Andorra and Morocco. The exchange capacity of this interconnection is around 3 GW, which represents a low level of interconnection for the peninsula. The international interconnection level is calculated by comparing the electricity exchange capacity with other countries with the generation capacity or installed power.

To me this indicates that in many energy markets where renewables are sufficiently built out, the only factor for why we aren't using them more is the storage capacity and grid infrastructure to handle their variability -- and instead just running stable but dirty energy systems.
There are a lot of cool mechanical grid systems like gravity batteries (e.g. weights on a pulley system) [2] or compressed or liquid air storage systems [3] which provide cheaper storage at higher capacities and durations than electric batteries

Definitely felt surreal to first lose power to the degree that even traffic lights were no longer working, and then to hear it's also happening across the region just before mobile networks also went offline.

I was an an adjacent area at the time and iirc we were saved by our nuclear operator releasing some insane amount of steam to bring the supply down and avoid more overloading.
The first night, we had 2 grills with 10ft high flames roaring but I would say in a controlled fashion. The cops quickly asked us to not do something dumb like that anymore and we agreed.
Memories of the local party stores selling 40oz's for pennies on the dollar, as the outage would last days but the booze would not. It didn't really turn into anything bad for us in SE Michigan other than a fun story I can tell my internet pals about 20 years on.
If I recall correctly, we were also somehow the first house in the neighborhood to get power restored...I remember playing a Dreamcast with a hacked NES emulator running Rampart 2 player. I never made good on it, but I always said I wanted to make a shirt that read "I blacked out in the black out of '03"...which is probably for the best.

> In January 1998, Montreal and the region surrounding it was hit by the most disastrous ice storm ever recorded: more than four inches of ice entombed an area larger than the State of Florida, causing trees and power lines to collapse on an unprecedented scale, leaving millions in the dark without heat (some for up to four weeks). 35 people died and damages totalled more than $5 billion making it the worst natural disaster in Canadian history.
4 out of 5 power lines to Montreal went down
Full grid failures are almost certainly never down to a single cause.

I mean, what else are you gonna do without power?
It’s funny to think how the moment is goes off you feel nothing, but hearing that many people produce noise and express happiness makes your body notice instantly, a sensation we often describe as electric.
Is a grid built on renewables and batteries somehow more resilient? Solid state things tend to be less fiddly, hence my question.
I remember reading at one point in the past that renewables were actually worse for the grid due to less predictable power generation or something, but that was a long time ago, certainly pre-battery storage.
So this is a complicated subject in itself, and a full answer won't fit inside this textbox. Some bullet points:
- Grid stability is maintained by batteries, but not literally. The "batteries" in question are typically rotating generators, i.e. turbines, wind, literally anything where you have an electrical coupling to a lot of physical inertia. That's what keeps the grid running second-to-second; while a power plant might pretend it's outputting a constant 4MW, it actually shifts noticeably from moment to moment. The kinetic energy of the generator helps balance that out.
- Going up from the sub-second range, an overload of the generator obviously would cause the shaft to slow down, dropping the frequency and causing brownouts. Brownouts are bad and can damage the grid, so typically breakers will disconnect if it falls below 49Hz; a 2% drop.
- Baseload plants can't cope with this, as they take multiple minutes to spool up. Minimum; for something like a coal power plant, where you have to shove in additional coal and wait for it to catch fire, it's going quite a few minutes. This is what defines 'baseload'.
- Peaker power plants can increase (or decrease) their mechanical power production in a matter of seconds. These days that typically means gas turbines, though hydroelectric power is even better, and nuclear power could be used for peaker plants -- but isn't; most nuclear reactor designs outside of the navy is a baseload design. France does have some load-following designs, and we need more of those.
- Wind turbines can't increase their output, flat out, but they can decrease it (by feathering, or by using brakes). This is good enough, except this would turn them into 'peaker plants' that can't help with peaks. If we had enough wind turbines to cover 100% of the load then we'd technically be fine, but economically speaking that doesn't work; they'd be at less than 10% power most of the time.
- Wind turbines have rotating shafts, but a lot of the time they produce DC power, linked through inverters, which removes that benefit and makes them act like solar panels in effect. However, this is a purely economic issue; they can trivially be upgraded to support grid stability if the pricing scheme will pay for it.
- Solar panels are worse: They have no inertia! There is no rotating shaft there to cover sub-second usage spikes. That's where complaints about 'renewables causing reduction of grid stability' come from, along with issues like domestic solar needing to backfeed power through distribution lines and transformers that aren't necessarily designed for that.
- But batteries can absolutely help. The kinetic energy of a rotating turbine isn't actually that big; it's not that expensive to pair a solar panel with a battery to build a grid-forming system that acts the same way a kinetic power plant would.
Growing up in Spain I've never experienced anything like this (not there at the moment, but friends have told me over WhatsApp).
The whole Europe power grid are somewhat interconnected I wont be surprise if this knock on effect start knocking out other surrounding countries.

Monero is the favorite payment coin when ordering real cyber attacks.
According to local newspapers metro network, airport and traffic lights are all down
Would be interesting to see if it will register here.
I know it may be rare but I think some day we really need to move or mandate every single flat / home / apartment / living places to have a 12 - 24 hours backup battery included. Something that has 10K+ Cycles, durable and non-flammable. Not only does it make sure our modern lives without sudden interruption, it also solves the renewable energy problem.
And even if we do want to invest in large amount of grid storage (which we would need to anyway, if we want to transition to renewables), I'm not sure pushing this down to the individual house is sensible. Its a great way to limit economies of scale and make maintenance/inspection harder.
That is just shifting someone else's mistake into being my responsibility.
If electricity is that important to you, buy your _own_ resilience. Tesla powerwalls and non-tesla equivalents have been available for ages.
- "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.”"

That makes it all the more important to learn these skills.
Calling attention to how fragile many of our critical systems are is almost certanly a net-positive in the long run.

This is literally the whistleblowers about cashless society have been warning everyone about for well over a decade now.
But a whole country’s grid can go down like this in an instant?
This is the absolute worst thing to do when there is a shortage of power - you immediately make the shortage worse and more grid disconnects.
The real fix is a grid with second by second pricing based on system frequency, and every individual user allowed to set a daily 'spend cap' of euros/dollars, letting them choose how much they are willing to pay for reliability.
Such an market has a huge stabilizing effect on demand, meaning a major incident would probably only have fairly small impacts on system frequency and embedded solar wouldn't disconnect.
That’s why you still need a strong diesel/diesel-electric locomotive fleet, imagine if Spain had been right in the middle military mobilization and military materiel transport, an event like this one would have stopped then dead in the tracks had they been relying only on electric locomotives.
