Suppose for the sake of the argument that renewables only produced power around noon. If you build more renewables until they produce more power than you need before you invest in storage you run your fossil fuel plants a lot more than if you invest a little in storage to be able to shift massive overproduction around noon to other times of the day. It's probably best if we increase the carbon price until the market figures out how much storage is economical.
