France seems to work. They have plenty of nuclear power that is flexible. And you can have other forms of consumption flexibility; otherwise wind and solar are really in trouble.

France is part of the EU power grid and flexibility comes from that not from nuclear power plants. And the government had to rise the subsidies for nuclear energy to prevent higher rises of the energy prices. The costs for the consumers still raised.
And their power plants were in trouble in the last hot summer because the rivers were too hot to be used for cooling. Won‘t be the last time. And that will be a big problem when people turn on their AC in a heat wave but the power plants can’t power up because they don’t have enough cool water.
And that was before drone wars were a thing.
People react nervously when unknown drones fly around airports and power plants.
And didn’t we learn from the internet that centralization is a bad thing? Nuclear power plants are exactly that.
Imagine a grid where every consumer is also a producer who can satisfy their energy needs at least partially for themselves even without the grid. Try to blackout that.
"France is part of the EU power grid and flexibility comes from that not from nuclear power plants." - blatant lie. You can see in generation data they are flexing a lot in the summer. https://www.services-rte.com/en/view-data-published-by-rte/g...
"And their power plants were in trouble in the last hot summer" - blatant lie. Cooling was fine, it's env protection law to avoid damaging the fauna(read - to not boil fish). Yet, it affects about 0.02% of annual generation and valid almost exclusively to NPP without cooling towers. Yet in those exact periods EDF was net exporting about 14GW to neighbors, again, data is public. French nukes can handle ppl's AC's just well, probably EDF even hopes for that to modulate their npp less and get more $
Why people always spread such nonsense without even checking the facts? Like https://www.vie-publique.fr/files/rapport/pdf/288726.pdf
"And didn’t we learn from the internet that centralization is a bad thing? Nuclear power plants are exactly that." France has a combination of centralized and decentralized power - npp's are distributed around the country but each can generate a lot of power. Even more distribution and you start paying a ton for transmission lines and maintenance. That's the reason Germany started subsidizing them from this year, with about 6bn/y. Full decentralization is not a feature and you still can't achieve it since transmission system is centralized, prime example being recent cascade blackout in Spain.
"Imagine a grid where every consumer is also a producer who can satisfy their energy needs at least partially for themselves even without the grid. Try to blackout that." - that'll mean having to need a fully parallel grid for firming. Besides, a lot of home solar are grid followers - if there's a blackout, it'll shut down too unless you have a special invertor+bess which many dont have (yet)
"And that was before drone wars were a thing." - a drone would do nothing to a NPP. Even an airplane impact can be tolerated depending how new is the NPP.

You do understand what the point of environmental protection is?
If you kill the flora and fauna you are not environment friendly.

France uses their own and their neighbors fossil capacity to manage nuclear inflexibility.
When a cold spell hits France exports turn to imports.
Now EDF is crying about renewables lowering nuclear earning potential and increasing maintenance costs.
The problem is that they are up against economic incentives. Why should a company or person with solar and storage buy grid based nuclear power? They don’t.
Why should they not sell their excess to their neighbors? They do.

No it doesn't. You can see it https://www.services-rte.com/en/view-data-published-by-rte/g...
French nuclear is more flexible than coal by design and as flexible as many older gas plants with ALFC system. They can reach up to 0.5%/second modulation (proved by Philipsburg) if the situation requires but it's rarely the case if you have a fleet. It's still not as fast as BWR's that can reach 1%/second but german coal is the slowest load follower and still meets min requirements imposed by the grid.
"When a cold spell hits France exports turn to imports." - was true in the past, a bit, but afaik this and last winter France was net exporting a ton. And with FLA3 reaching full capacity this year it'll be even less of a problem. It's not like they have a problem now, they are the largest net exporter on the continent and it's unlikely to change soon.
"Now EDF is crying about renewables lowering nuclear earning potential and increasing maintenance costs." - yes, because ren generation is acting like a parasitic source without proper BESS deployments - they eat into firm power profits without providing firm power benefits.
"Why should a company or person with solar and storage buy grid based nuclear power? They don’t." - because in many places of the world solar+bess are not sufficient. It's also the reason why Microsoft signed a contract for TMI way above market prices instead of building a fully offgrid ren solution
EDF is selling power to neighbors and makes money from it. It also is modulating it's npp a lot, which will maybe change when AC's will be more widely deployed and EV's will expand. It also is trying to schedule most maintenance works in summer, during lowest demand periods
