as a counterpoint, nearly every grid-attached power storage system I've seen has been almost entirely described/discussed in terms of "useful for renewable power", i.e. the duck curve. though it doesn't often get mentioned by name. the exceptions are either A) they also mention how e.g. nuclear power is very limited in its ability to change output at all, so it's also useful for day/night power imbalance in general, or B) they target short-term spikes and dips to e.g. allow gas/coal time to adjust.
