Seems they are digging pretty hard to find a downside to renewables and managed to come up with the Duck curve, which CAISO predicted, analysed and solved over the last decade.<p>I guess mentioning the prior art would have made their pronouncements of doom seem even sillier:<p>> Failing to account for increased cycling stress of the dispatchable thermal fleet is a fundamental flaw in most energy transition models, and must be addressed directly to paint a realistic picture of a resource mix that includes more renewables.<p>Oh that sounds scary, what's is the solution? Buy some batteries and phase out fossil fuels even faster while saving even more money? Well that doesn't sound too bad when you put it like that.
