The long term plan was always EU-wide energy projects to account for “its cloudy in Germany” scenarios. That plan isn’t complete.
Again:
- is it war that makes renewables produce 15% of their installed capacity?
- is it war that made Germany shut down 20GW of nuclear power plants?
> That plan isn’t complete.
And it never will be complete. Because when it's cloudy in Germany, those clouds don't stop at Germany's borders. Literally see the comment above about Denmark.
No form of power meets its theoretical "installed capacity". No one runs their nuclear, gas, coal, or oil plants at 100% 24/7/365 either. Yes, some days it's less windy; some days it's more cloudy. The dramatic fall in cost for new solar and wind capacity makes the solution pretty obvious; you build more to account.

It's war that makes Germany temporarily wish they hadn't.

They're unlikely to cover the entire EU's interconnected grid (and there's talk of generation in Morocco; https://www.washingtonpost.com/climate-solutions/2023/04/13/...). When the entire EU is covered in clouds, it's especially unlikely that there's no wind at the same time.
Given Germany's plan is 60% renewable generation by 2050, not 100%, they clearly understand the need for some flexible options for the tail ends of things.
And yet unlike renewables nuclear (and coal and gas etc.) are very close to that. And nuclear routinely runs close to its capacity, predictably.

So each EU country has to overprovision enough solar and wind to potentially generate power for the rest of the EU countries? Case in point: https://news.ycombinator.com/item?id=38276778
Sure. Apples to oranges; they're not the same thing. Theoretical perfect-day max generation isn't how you provision solar/wind, that'd be stupid; the folks building out Germany's renewable efforts aren't stupid.
If you need a certain baseline of a certain renewable, you overprovision (and trade capacity with other areas and generation methods). Given the cost of new solar/wind capacity these days, that still makes perfect economic sense. Any long-term renewables plan is going to include energy storage and peaker plants of some kind to ensure a reliable grid on a national/continental scale.
How much? Is 200% of required generation enough? Is 500%?
Germany - and the rest of their interconnected EU grid - will continue to build out cheap, clean power for the forseeable future.
Ah yes. This war is the reason why 134 GW of renewable energy only produce ~20GW, and why Germany burns 20 GW of coal (by pure coincidence that's about as much as the capacity of all decommissioned reactors since 2011)
