While the claim that nuclear plants can operate in load-following mode is technically true, in practice the wear from ramping and the extremely high-CAPEX nature of nuclear make this impractical. This is why you don’t see nuclear plants ramping much in the United States, and why such plants will accept negative electricity prices instead of ramping.

Nuclear power is the least flexible of conventional generation sources in practice.

I noticed that the table given in this article has several assumptions that boost solar/PV and burden nuclear. As a few examples, nuclear looks terrible if you assume it can only operate as baseload at 100% load. In actuality, all modern nuclear plants can operate in load-following modes at a small increase in fuel costs, giving abilities similar to hydro. Conversely, wind and, solar/PV are rated good for dispatchability. How do you dispactch solar at night and wind on a calm day?
I like to say that with the right assumptions, you can prove anything.

In reply to Dwain Wlki5. Dwain: You may want to look into the Solar Head of State initiative, which is focused on renewable energy for small island nations.

Good morning,
I live in the Bahamas and think that that is a fantastic idea. I have been looking fo some no ideas that we can put to use in the islands. I would very much appreciate it if you can send me any info that you feel can assist.
Thank you
