    Could a dam lake be counted as hydro storage? That wouldn’t require energy spending to pump water up, but it can work as a “cache”?

      Nope, that’s just regular hydroelectric. All hydro power plants have valves to control the flow and they do adjust them on demand, for turbine/filter maintenance, and/or hydrological event control.

      Also, dam lake is a misnomer because lakes are naturally occurring. The correct term is reservoir. However, a reservoir can be natural and not dammed, like the oldest Czech pumped storage power plant at Černé jezero, which I visited. (The reservoir is a beautiful mountain lake and unfortunately, nature preservationists capped the water level changes to 4 cm, limiting capacity.)

        Yeah I didn’t know the correct term for it in English, in Finnish it’s called “fakelake” or maybe more accurately “artificial lake”, but fakelake sounds better
