The French find out that the combination of nuclear energy with unstable wind and sun is not a good idea and is a risk to the power grid.
Spain recently had to learn a similar lesson in a very painful way.

In a recently carried out EDF report on nuclear security, the general inspector's report for nuclear security and radiation protection, leading author and training Admiral Jean Casabian came to the conclusion that a further expansion of wind and solar energy in France is a serious risk of the country's power grid.
According to the report, the instability of a weather-dependent wind and solar power supply for nuclear power in France is a technical and financial burden.
Page 13 of the report means:
The massive arrival of new renewable electricity sources (Re), both intermittent and a priority on the net, has multiplied load fluctuations.
They are neither without a risk of the safety of the power supply system (including power outages) nor without restrictions on the operation of our facilities. In the long term, you question our economic model. (…)
The modulation has from flexibility to restrictions, whereby the nuclear energy must satisfy demand alone or in connection with hydropower, unless we use thermal and carbon -intensive agents.
In addition, the load has a frequent influence on the machine, which is classified more often by deep cycling. The increase in random events is not obvious, but the effects are estimated over time.
I believe that the priority of renewable energies in a one-sided, nuclear-renewable energy scheme leads to performance fluctuations that would be all the cheaper to do without security, since they are never insignificant in terms of security, especially reactivity control, and the waiting, long and operating costs of our treats. “
Many previously claimed that the nuclear industry could be harmoniously paired with wind energy and thus lead to a decarbonized French electricity mix. But that proves to be more fantastic than reality. The latest Spanish power failure was a blatant example of what can happen if the ideology speaks together with hard science and reality.
Many engineers and specialists had warned of the risks and complications associated with nuclear power plants to adapt their performance to uncontrolled, fluctuating energies such as wind and sun.
Aassdn site summarizes here:
In the global energy war, which is conducted by this pro-wind and pro-Photovoltaic lobbying in France, which contradicts the energy interests of France, this discrete report appears to the intermittent energy policy in France. Even if energy and political players have not yet fully grasped the importance of this historical technical report, it cannot be denied that it is a milestone and cannot be buried or downplayed by Luc Rémont, CEO from Edf. “
