Actually model it. Go look at gridwatch and use the graphs to calculate total storage needs if using a wind-solar mix, then check out the US department of energy 2019 report on energy storage solution characteristics.
Calculated total cost when I did it would have tripled UK electricity prices.
Pure French nuclear, on the other hand, resulted in a mere 30% increase in electricity prices.
Yes, over regulation leads to massively spiraling costs as delays lead to financing issues (both interest and uncertainty), knowledge loss, project management timing issues, etc etc
And yet even with that you're getting 400 billion kWh over its 40 year lifespan for €13 billion construction costs (multiply by 1.5 for lifetime costs), for electricity production price of €0.05 per kWh. Which is honestly decent.
Btw: did you actually do the calculation before posting?
