The reality is that Spain's electricity is cheap because it is relatively insulated from Europe's core network, because its interconnections with other countries are limited. In financial words, there is a spread with the rest of Europe because the ways to arbitrage that spread are extremely limited. If Spain was located near Germany and well interconnected, their prices would look like Germany's. And while cheap energy is pictured by op as a good thing, Spain understands very well that higher prices are good for its renewables industry, and is pressing for more interconnections[1].
The overall tone of the article feels like the author is here to extoll the virtues of renewables.

The best candidate for lowering prices would be France, but France would most likely re-export that electricity to other countries, and paying to build up the internal grid to carry electricity that is neither bought by nor sold to French actors isn't very attractive.
Ideally Spain would interconnect with Italy, but that's more expensive.
The one question the article leaves open, but which is pretty relevant, is the question about who should pays for stability services to the grid.
And for the numbers it seems obvious that renewables are a fundamental part of the picture.
Heck, oil is probably the "default" example of what a commodity is, but we're now all acutely aware of what happens when moving that oil from one place to another becomes exceedingly difficult.
It is not. As a case in my point, Spain had a blackout last year (and I completely believe they are competent professionals - the task is just hard).
> It's just that those interconnections haven't been built yet.
They haven't been built because the grid isn't just a technical problem. It's also a socioeconomic problem, and adding new interconnections would require finding who needs to pay for it ; and currently, that question has no answer.
If your local price is high you can import, if it's low you can export.
If you're at the end of a grid and/or your transmission capacity is limited your price has the possibility to go higher or lower without that damping mechanism.
Electricitymaps has a pricing layer which seems to show central Europe moving in sync when I randomly check it:

If you have a steel mill for example you need to be able to basically guarantee a certain level of energy production to run it viably because the risk of there not being any power during adverse weather is enough to make it unviable (you can't just turn these things off). This is the reason why gas and nuclear probably aren't going away (or at least shouldn't).
If they increase in price then firm production is stimulated to build to meet the gap.

Probably when combined with batteries it is half the price.
There are some colder areas in northern europe especially where solar doesnt work as well but they also tend to be better served for hydro (which can also store power).
There are already a bunch of examples of Northern locales using these heat batteries - just heat up a big block of something when energy is cheap and solar/wind are overproducing, then use a network of insulated pipes to distribute that heated water.

(for Australia it is 5, for other countries it might be 8)
Once you get to that "nice to have" problem of what to do about the remaining 3% of power needs it would probably make most sense to synthesize and store gas (methane/hydrogen) from electricity when solar and wind is overproducing. Gas can be stored cheaply for long durations. The roundtrip efficiency is poor but it's still cheaper than nuclear power on the windiest sunniest day.
The nuclear + carbon lobbies would of course prefer to model green energy transitions by pretending that the wind and sun simultaneously turn off for 2 weeks at a time every year and that electricity can only be stored in very expensive batteries. This is not realistic.
This is simply entirely untrue. Europe's a big place, there's not a single day ever where there is no sun in it.
In most places, if you buy more of something, you are a good customer, it is usually more economical to sell to you and you get a discount.
In california people who use more kilowatts, pay more.
The less energy you spend to deliver value, the better for everyone.
Moral bankruptcy.

regardless of inflamed speeches eu simply cannot operate without that energy. should have thought about that before starting a war with russia. best of lucks!
YES THEY DID, they went as far as making nuclear power plants shut down due to negative prices so their reliable stable power wasn't a pacemaker anymore and it blew up in their faces. And this was a topic on TV shows with several experts alerting of this FOR MONTHS before the blackout.
Sure, there are new technologies to stabilize solar and wind's fluctuating outputs but they are no just plug and play. Those are very, very complex systems that take years to set up properly. While there are nuclear power plants are just there collecting dust because the EU pressured Spain to make them unprofitable to maintain so they would be shut down.
Luckily, the US-Israel-Iran war made the EU leadership turn and now they want nuclear. I hope it's not too late.
1. Stable power grids are much easier with a mix of generation sources that includes substantial rotating mass and baseload generators.
2. Nuclear is awesome from a climate change and energy security point of view, and it would be amazing if it were cheaper or more valued.
When power was primarily generated by thermal plants with big rotating masses, we got frequency control implicitly from the inertia of those generators. When there was a demand spike, the generators handled the millisecond to few seconds regime just by their inertia, while the seconds to minutes regime was handled by plant control systems increasing throttles or starting more peaker plants.
I disagree that renewables themselves are the problem. Cheap solar energy does not have to mean that we shut down all the uneconomical generation sources, nor does it mean that we cannot do FCAS with modern technology.
Battery electric storage systems have actually eaten much of the FCAS market in the USA, where they can respond way more effectively and efficiently than other systems in the 1 to 10 second regime. By and large, we don't store solar energy for use overnight - we store it (or really any energy) for use in smoothing short demand spikes.
I would love to see more nuclear, and more advanced nuclear. Modern designs are safe, effective, and amazingly capable. They just aren't as cheap as paving the world with solar cells or burning natural gas left over as a fracking byproduct.
This really depends on the amount of battery storage installed. In California we now see battery discharging through to the morning.

They don't _actually_ want nuclear, luckily it's just lip service. Because it doesn't solve the problem surfaced by the US-Israel-Iran war: You'd still be dependent on other countries for your (nuclear) fuel needs.
Like Canada and in the future also Sweden? Two really hostile countries to be dependent on.
That was not a stabilization problem per-se, but the companies that had to do the stabilization just didn't although the were being paid for that. Please read the final report.
And no more blackouts because now they are running nuclear 24/7 to keep things stable.
And again, it's not completely Spain's government fault as it obviously came from the EU and their anti-nuclear stance.
People didn’t do what they said they’d do: No problem with the system it’s the people that didn’t do what they said they would do.
