Spain and Portugal power outage: what caused it, and was there a cyber-attack?
Several countries in Europe have been scrambling to restore electricity after a huge power cut caused blackoutswww.theguardian.com
TLDR: atmospheric, not cyber
It doesn't matter if the cause is natural or provoked. Europe can no longer stand one more lie.
Renewables are nothing more than stupid toys... what will happen when we have another Maunder minimum, another cycle of sunspots, another little glaciation?Do you mean renewables?

Train services in both countries stopped, leaving tens of thousands of passengers stranded.
It wouldn’t be possible to restart trains later Monday even if the power returned, Spain’s Transportation Minister Oscar Puente posted on social media.
Experts have previously said that the rapid expansion of wind and solar power is putting increased pressure on the Spanish grid, which is in need of an upgrade to handle record volumes of intermittent renewables.
But green energy was not to blame for Monday’s blackout, Meeus said, since the EU has in recent years enforced several sets of rules, like updated grid connection codes from 2016, to prevent renewable power generators from disconnecting from the network in a way that endangers the system.
“The nature and scale of the outage makes it unlikely that the volume of renewables was the cause, with the Spanish network more often than not subject to very high volumes of such production,” added Daniel Muir, senior European power analyst at S&P Global.
“There was sufficient conventional generation available, with nuclear, hydro, cogeneration and thermal technologies all on the system prior to the event and ... available to the operator,” he said.
I'm sorry to hear that, but I have to point out that the blackout is not a new energy problem, but an inaction on the part of some people. Some people don't care about how new energy can serve the people, and have taken some irrational approaches. Renewables are certainly the way forward, but there are also a lot of uncertainties, so I think it's reasonable to reserve some thermal power generation in case it is not prepared. In my country, the proportion of new energy sources is gradually increasing, but a fairly large-scale thermal power generation system is still maintained. But it is unreasonable to deny the prospects for the development of new energy.Renewables are nothing more than stupid toys... what will happen when we have another Maunder minimum, another cycle of sunspots, another little glaciation?
Enough of the nonsense, in my country environmental legislation is killing people and no one pays for it!

The cause was unclear, with Portugal suggesting the issue originated in Spain and Spain pointing the finger at a break-up in its connection to France.
Portuguese Prime Minister Luis Montenegro said there was "no indication" a cyberattack had caused the blackout, which began at around 12.30pm local time yesterday.
Nonetheless, rumours circulated of possible sabotage, and Spanish Prime Minister Pedro Sanchez said he had spoken to NATO Secretary General Mark Rutte.
Mr Sanchez said that the country had suffered a loss of 15GW of electricity generation in five seconds, equivalent to 60% of national demand. Technicians were working to figure out why that sudden drop occurred, he said.
The large-scale new energy connection to the power grid not only affects the safe and stable operation of the power system, but also significantly affects the operation economy of the power system. After the new energy is connected to the grid, the conventional synchronous generator set is replaced by wind power and photovoltaic generator set, resulting in the reduction of the moment of inertia of the system and the reduction of frequency regulation ability. The grid-related performance standards of new energy equipment are low, and the frequency and voltage tolerance are poor, which is easy to cause off-grid problems. Due to the fluctuation and randomness of new energy resources, and the low immunity and weak support of power generation equipment, the effective consumption and safe operation of new energy are the world's problems.It's not a capacity issue. It's not a renewables issue. It's a grid-stability issue. The US Northeast blackout of 2003 was down to software, the 2003 Italo-Swiss blackout was down to poor understanding of load-shedding by the Swiss control room, etc.
The last major UK outage did involve a wind farm going off line when it shouldn't have, it also involved a gas turbine power-station going off-line when it shouldn't have.

NSW-owned Transgrid said on Tuesday it remained committed to delivering the EnergyConnect project that will create a new energy transmission line that will provide cheaper energy to people in NSW. Clough was a part of the consortium selected to build the project alongside partner, Spain’s Elecnor.
I've seen places where the keys are kept on a big loop and the train crews hand off the keys at specific stations. On the move, no less!While here in my country, the diesel-powered locomotives could still run in a large blackout, the question is, do they have a way to manually operate the track switches/turnouts/points which are now normally remotely actuated by a central dispatcher?
How many train crews have the required keys, et cetera, to unlock them and operate them the 1800s way?
What of the radio communications would remain; the locomotives are their own power supply, but what about the radios at dispatcher and Centralized Traffic Control offices?
I know railroads have contingency plans for such things but it has been something like a quarter century since I was involved with railroads.
As,a German, I have to say, this sounds very familliar...Yesterday my country was the greenest in the world when the electricity grid worked for tenths of a second with 80% renewable energy, then the complicated compensation system could not control the oscillations between supply and demand and collapsed, creating historic chaos. There have already been some deaths, but yesterday we were the greenest country and an example for the rest of the world. We continue to close carbon power plants and destroy them so that they are not used again, and nuclear power plants for reasons of ideological blindness.
We have only been able to gradually reactivate the electricity system thanks to the nuclear energy supplied by France and, to our shame, we must also thank Morocco for its help.
That is interesting. There was a 3 hour powercut very close where I live in Lancashire at 6pm on Sunday 27th to a "unexpected incident on the high voltage cable" (though where I live didn't lose power).![]()
Britain hit by unusual power activity hours before Spain blackout
The UK’s grid operator is investigating unexplained shifts in electricity frequency on Sundaywww.telegraph.co.uk
Those aren't the point keys, it's a token system to guarantee only one locomotive on a piece of track at a time.I've seen places where the keys are kept on a big loop and the train crews hand off the keys at specific stations. On the move, no less!
But that was noted in the videos as being an unusual thing and not how it was normally done at all. Only done at those places because the track signals and switches were not automated.
In general train crews didn't operate the points, that was done by signalmen, who both knew what was scheduled and when, and were in contact with the rest of the network in order to react to changes.How many train crews have the required keys, et cetera, to unlock them and operate them the 1800s way?
Two references I know about for that,There doesn't seem to have been any unusual solar activity during the weekend that was flagged,
