New research shows renewables are more profitable than nuclear power
(www.pv-magazine.com)
This is a most excellent place for technology news and articles.
German nuclear plants can swing from 700MW to over 1300MW per day. Some nuclear plants can manage two swings per day, and these are OLD designs.
I still don't think that would work as a peaker plant, but it's better than nothing! If they really have improved it more than that it might work, but you are going to need at least one power source that can be meaningfully changed multiple times per day.
