Because the nuclear reaction is not dependant on the wind blowing to produce energy.

It's not 100% because you need to do maintenance at times.

Perhaps I wasn't clear enough, I was alluding to the lively debate about how the selling price for electricity is set, and how it should vary depending on market conditions.

I see no reason to lock-in minimum pricing for any kind of electricity generation many decades in advance. Why is that necessary for new nuclear plants?

In other words: do we need to guarantee a minimum market price 30 years in advance in order to make it look like building a nuclear plant makes economic sense?

I would think that they'd run it closer to 100% and do all the maintenance during a scheduled outage...at least that's how I understand they do the maintenance planning/scheduling at Palo Verde.
