IMO this needs some citation. The ones I'm aware of are these big expensive spanish power plants. I think this is neither simple nor cost effective compared to batteries, plus the energy is AFAIK only stored short term.

No one builds them though because there isn't a lot of need currently. Mostly I think because it's cheaper to build a natural gas fired peaking plant than time shift say electricity from coal fired plants. However as we add more wind and solar this should change.
