At least Sweden is struggling a lot with scaling its power production, to the point where it's a problem for existing and new industries and causing some rather extreme price volatility.
A lot of the green energy is from hydro dams and you can't really add new rivers to the geography to support additional industry.
With hindsight, it wasn't a very good idea to shut down 6 of 12 nuclear reactors. Still much better than the situation in Germany, but that's a very low bar.
It will be interesting to see how the Rolls-Royce SMR project works out. Since it appears to be impossible to build anything cheaply in the UK, this will be the real test.

The solution is to build nuclear power stations on ships in China, then sail them to the UK and plug them in.
If power prices elsewhere in the world become advantageous, sail them elsewhere and plug them in there.
You still have the interconnection costs, but seaside places sometimes have high voltage connections for existing or historic power plants (who themselves are water cooled)
A Chinese nuke on the coast of Britain might be hard politically. Even if it's benign, you can bet the US will run an expensive campaign to discredit it in public opinion.
There's a special line crossed by a 100% Chinese owned floating nuclear power plant, as opposed to a 24% Chinese owned fixed in place nuclear power plant like the Hinkley Point C nuclear power station?
You wouldn't even need it to be Chinese owned. Just Chinese built and indemnified. Hell, I'd take a guarantee from a consortium of Chinese SoE banks over the U.S. government today. (I'm American.)
The government that keeps rejecting offshore wind for bogus security reasons is probably a bigger factor.
Those wind farms would have connected into the zones with the highest prices.
They've rejected an amount that would generate more than the entire grid usage. Or way more than double what the cheap zones generate from their 2/3rds hydro and 1/3rd wind.
>you can't really add new rivers to the geography to support additional industry.
yes, you can - with all those fiords surrounded by mountains you can use excess wind/solar (your own as well as German, etc.) and pump water up a dammed fiord to generate the electricity later when no cheap excess available.
This assumes that there is excess power at some point. This will soon become unrealistic: we either need power for data centers during the day or charging vehicles during the night.
The solution works only to keep a steady production of electricity, but if the demand would require full output all the time then these "mechanical batteries" don't help.
