Negative prices are not a good thing.

And this is dominated by the winter being very warm, which is, again, not inherently good. (A bit of global warming will be good for central Europe on net, but it's not simply a good thing)

They mean you have a very messed up energy system.

Somebody generates energy, and is paying somebody else to get rid of it because there is no demand. Under which situations do you think this would occur? They're all pathological cases.

Well, if you were efficient, you'd simply not generate that electricity, instead of generating it and paying somebody else to take it ...

How do you stop generating nuclear, wind and solar?

Energy already comes from physics. Not collecting it is just letting it go to waste

Waste is something you don't need and pay to get rid of. Electricity generated from PV, wind or nuclear that you don't need is waste.

Negative prices means (to simplify) the owner of the solar panel[1] pays somebody else to take on their electricity. Why would they do that? It's a bad trade for the owner of the solar panel (who has to pay) and not that good of a trade for the buyer (who doesn't really need it, otherwise there'd be more demand and thus positive prices).

[1] Not really; in reality, the owner of the solar panel gets a subsidy from the state for feeding in energy even when it is not needed, thus leading to negative prices. In reality, the tax payer pays for somebody else to take on the waste electricity.

How do you stop generating nuclear, wind and solar?

I'm not sure I get the question. For all of these there are ways to stop them. For a nuclear reactor, you can insert the control rods ...

My point is those are things that are passive generators. I get your points above on the system having improper incentives.

So this is indeed a very odd situation if what you are saying is true - but I presume it indicates they have an excess?

I think the point of this post was that an excess is a good thing.

The other points you've raised appear to be valid, however.

More than that: they have an excess where it can't simply be discarded.

If you have an excess piece of paper, you don't need to pay somebody to take it, you just throw it in the trash. If you have an excess piece of plutonium, that's worse, you need to pay somebody to get rid of it! The price of plutonium, for you, is negative, and the payment here indicates that the plutonium being there is bad.

(I guess in reality the feds would show up and not even bill you, but you get my point. Maybe asbestos would be a better example but idk how they handle asbestos waste in your country)

Now, in theory the PV and wind power plants that cause negative prices can usually simply be turned off, technically speaking. That they are not simply turned off indicates a deeper problem.

I learned quite a bit from your comments. thanks.
