'No big deal" Just an atmospheric phenomenon' some outages green energy absolved

[putnam6]

Given the geopolitical context of current events I wouldn't be surprised if this was a demonstration of capabilities.

The thought did cross my mind...

Analysis: Why this power outage has happened - and the tough balancing act it now needsBy Tom Clarke, science and technology editor
We rarely think about how essential and reliable electricity grids are until they fail.
Now, millions of people across Spain, Portugal and parts of France are likely thinking of little else.
While local power cuts are fairly common, what's happened across the Iberian Peninsula is something far more extreme. 
Much of Spain and Portugal's electricity transmission system collapsed in seconds, including major cities Lisbon, Madrid, Barcelona and Seville.
It's likely the outage will surpass Europe's largest blackout to date, when 56 million people in Italy and Switzerland lost power for up to 12 hours in 2023.
Unlikely it was a local event
The cause of the outage is unclear.
Portugal's grid operator has blamed a "rare atmospheric  phenomenon" that caused "anomalous oscillations" in high voltage power lines in Spain.
Spain's grid operator has yet to respond to that, or provide an update on the causes.
But it's unlikely whatever caused the outage was a single, localised event. 
A major power line going down can cause a large outage (as it did in 2021 when an interconnector between France and Spain failed, leaving a million people without power for a few hours in 2021). 
But it's unlikely to cause a system-wide failure of the kind we're seeing now.
The complex balancing act
However, when things do start to fail on a power grid, they can cascade uncontrollably.
Keeping a grid running is a constant and highly complex balancing act.
Spain's mains AC electricity supply grid, like ours in the UK, runs at 50Hz. That frequency is based on the speed at which generating hardware like gas and nuclear turbines spin at.
If there are sudden fluctuations in power supply or demand (a power station failing or a high voltage power line going down, for example) the frequency of AC power in the transmission lines changes and circuit breakers trip to protect either the transmission network or power plant hardware from burning out.
To prevent such failures, grid engineers constantly measure and forecast supply and demand to keep the grid balanced.
It could take far longer
To protect the system in emergencies, they occasionally have to "shed load" by cutting power to parts of the grid - the reason we've all experienced the occasional short-lived power cut.
But if balance is lost, a grid can fail in a domino-effect with sections of the grid tripping, then power plants shutting down to protect themselves from the drop in demand one after another. 
The challenge now, and it's a nightmare for Spain and Portugal's power engineers, is to gradually restore the grid section by section while maintaining the balance of supply and demand.
Act too fast, and the grid can trip again. Take too long, and some power plants or substations might struggle to restart - especially if they rely on battery power to do so.
While some regions of Spain have already had power restored, and Portugal says its power will be back to normal within hours, it could take much longer for the system to be fully restored.

Induced Atmospheric Vibration (IAV) in high-voltage power lines refers to low-frequency oscillations (typically 0.1–10 Hz) caused by corona discharge effects near the conductors. Here’s a brief breakdown:

Cause:

When high-voltage lines operate near their corona inception threshold, ionization of surrounding air molecules occurs, creating space charges (ions and electrons).

Under certain conditions (e.g., high humidity, rough conductor surfaces), these charges interact with the electric field, generating periodic electrohydrodynamic (EHD) forces.

Mechanism:

The EHD forces induce pressure waves in the air, causing vibrations in the conductor or nearby objects (e.g., insulators).

Unlike aeolian vibration (caused by wind) or galloping (large-amplitude motion), IAV is driven purely by electrical-atmospheric coupling.

Effects:

Usually low amplitude but can contribute to fatigue over time.

May exacerbate other vibration modes or cause audible hum.

Mitigation:

Smooth conductor surfaces (e.g., polished or coated wires).

Optimized voltage gradients to minimize corona.

IAV is less common than mechanical vibrations but is studied for its unique electromechanical interactions. ...

The vibrations can lead to fatigue cracks and loosened hardware.

That sounds all very technical so...

It was obviously HAARP.

I mean, I really dont know, but they haven't been brought up yet, and this is a conspiracy site, so it sounds like something HAARP would do. They just turned it from "Earthquake" to "power outage."

Why is it always 0.1 to 10 hertz? Always those ELFs. It is the most common crazy resonant frequency range. Especially if it was around 7.83 hertz.

Um 16:10 hat sich die Stromversorgung in Spanien noch nicht wesentlich verbessert. Für den Schwarzstart benötigt man konventionelle Kraftwerke wie Gasturbinen, Kohlekraftwerke (den größten Teil hat Spanien stillgelegt) oder Pumpspeicherkraftwerke. Solaranlagen sind nicht

Translated from German by
A black start is the process of restarting a power grid after a blackout without an external power supply. This involves using conventional power plants such as gas-fired or hydroelectric power plants, which can generate electricity independently. These first start small generators, which then activate larger power plants to gradually restore the grid. Renewable energy sources such as solar panels are unsuitable for this purpose, as they require external conditions (e.g., sunlight). In Spain, with a high share of renewable energy, the black start is crucial, especially after the major blackout on April 28, 2025. Conventional power plants remain essential for this.

Haha, I think Im following along, though you might need to explain it like Im 5 

... so our tech for collecting and distributing green energy might have unknown or unimagined weaknesses.

sounds like the temperatures created oscillations in the inverters?

Inverters are much more sensitive to any variation. They are designed to compensate to load changes really quickly. Unlike spinning generators that have a flywheel effect of being unable to change the amount generated by the millisecond, the inverters are capable of varying their power faster than the AC power cycles. In this case 50 hz.

Now, if a few inverters detect some interference and try to compensate for it, it can cause other inverters to respond to the variations of the first problem inverters. They can all end up fighting eachother, trying to stabilize the power. This will cause variations in that power and at some point the system is designed to just shut down instead of burning down from these types of problems.

When the inverters go down, because they have so much of the generated load, as you posted above, there is no hope for the rest of the power generators to carry the overload. The rest of the grid shuts down from simple overload of generating capacity.

Cascade failure. Part of the system fails which causes the whole thing to fail.

It sounds like France got lucky and stoped it from taking out Europe.

Each inverter may work great by itself or in groups but the length of the wires between the groups may cause them to interfear with eachother. Solar is DC so must have inverters to put the power to the national grids. And like I said, that is new technology on the grid that is untested how they are trying to use it.

The rare atmospheric conditions ... WTF  Sounds very HAARPish 

Are they suggesting the oscillation was caused by atmospheric heat? 

I need somebody to explain it like Im Ice T on LAOSVU

Thanks .... you explained that perfectly.... 

But where do the rare atmospheric conditions come into the equation?
 

All of Spain's nuclear reactors safe from power outages, says councilSpain's nuclear safety council has said all seven of the country's nuclear reactors are safe.
Four of them stopped operating automatically once the power cut hit, after which point emergency generators kicked in.
The other three reactors were not operating at the time, but emergency generators switched on anyway to keep them in a safe condition, the council added.

Exactly. Power grid inverters need a power reference to add their power to. They can't actually start generating themselves without a reference because they are specifically designed to add to an existing power system.

Only the off-grid solar power systems are designed to do that.

Possibly a tiny loose intermittent connection. Possibly a passing police car with a bad radio. Possibly a tree brushed a power line at just the right couple of contact intervals. The possibilities are endless.

It is even possible that connecting to the European grid induced a ground reference interference problem. You never know until you try the connection.

It is surprising that things like this don't happen more often. But then again, they technology of spinning generators is much better understood form experience than the inverters. They just have not been around long enough to correct all the possible problems with them.

The atmospheric explanation is just some handwavium to be saying something to keep themselves looking like they know what they are talking about. Could be an AI generated statement to MSM.
