> If nuclear is indeed able to throttle output up and down to match demand - or perhaps we should say, to match spot pricing(!) - why on Earth would we need to fix a minimum price for decades in advance in order to attract investment to build new ones Lots of reasons, one of which my sibling comment by user akvadrako has touched on. The question of whether it's currently economically viable to do so is a separate discussion. You persist on making this odd logical syllogism - if nuclear could throttle, the market would look like X, the market looks like Y, therefore nuclear can't throttle - and keep ignoring the technical fact of the matter that nuclear plants can in point of fact throttle. I have already linked to robust corroboration of this fact so I don't think there's any more for me to say here.
