> dunkelflaute is a problem, they are as rare as events No. They are actually much more frequent than renewable-advocates claim. > events where a nuclear power plant has to stop production for an unexpected reason. That turns out not to be the case, well-managed nuclear power has a capacity factor of well over 90%. But you're missing a much more important point: unforeseen events at nuclear power plants are independent and uncorrelated. So maybe 1 plant goes down, the others continue to operate unaffected. A Dunkelflfaute knocks out all your power over a large area.

What do you mean? We currently have solar and wind generation deployed. We can SEE the graphs, see by ourselves where it happens. Where are these "more frequent" events that you say are somehow hidden by renewable-advocates? And why the company that have solar and wind AND are also strongly invested in nuclear and other generation are helping them hiding them? As for the well-management and the area: a "well-managed" central is not worth much if so far the majority of the centrals are not reaching that level, and nuclear centrals are too expensive to be build to be redundant, so when one central goes down, it's a big chunk of the generation that is missing, and cannot be covered by the central next door because the electricity of the central next door is already used to satisfy the demand the next door. If you use the central next door to fill up the gap, who is going to fill up the gap in the demand next door? Funnily, if we go deeper in the question, people always end up explaining that of course they will install redundancies and flexibility (either by battery, by demand response, ...), shooting themselves in the foot because it itself mitigates a lot any problem created by dunkelflaute.

  It's not Germany but I always trot out California's electric supply This is a high quality display of current and past supply. You can see everyday you get a huge slug of energy from solar. You go through history and you can see a few days a month in the winter when the output drops by 50%. Also notable is California exports power during the day and batteries are providing a lot of power during the morning and early evening. https://www.caiso.com/TodaysOutlook/Pages/supply.html https://www.caiso.com/TodaysOutlook/Pages/supply.html This gives the mix over the last 12 years. https://www.energy.ca.gov/data-reports/energy-almanac/california-electricity-data/california-electrical-energy-generation https://www.energy.ca.gov/data-reports/energy-almanac/califo... The amount of hydro varies a lot. But it seems solar and wind are slowly depressing the demand for import and nat gas sources. It's an interesting compare to Germany. California never went in on nukes and hasn't forced existing plants to close. Wasn't dependent on Russian gas for power and chemical feedstocks. California continued to build out solar while Germany stopped. Bonus German dependency on baseload imports from Frances aging nuclear reactors. Feels like Germany has an excess of black chickens coming home to roost. Also notable, that hippy progressive unicorns and rainbow state of Texas has about the same amount renewables as California. Which says the Accounts books tell them the same story.
