First, it’s rare to have protected periods where the entire grid has no wind, solar, hydro, etc. That can happen regionally, but it’s not a secret and grid operators prepare for it just as they do the impact of heatwaves shutting down nuclear or fossil plants getting iced up.

Second, power is so cheap with renewables that storage of over-production makes sense. Some of that can be things like pumped water systems but batteries are coming online by the hundreds of gigawatt-hour now and sodium isn’t exactly a rare earth mineral so that’s going to accelerate even more following market forces:

Again, this is so much cheaper that it makes nuclear even less competitive and it’s online so much faster that you’re basically weighing the gamble that storage which is already competitive won’t get substantially cheaper over multiple decades.

Heavily disagree. A ”green” power contract typically has at least double the price of a generic one.
