My understanding is the hydro / water storage system is ideally a water tank / pond / reservoir / lake on a mountain / high place .
A combination pump / generator at a much lower elevation , with a big pipe between .
Water is pumped to the higher elevation and stored , using off peak power . On peak , the water flows down to the lower elevation , spinning a turbine which spins a generator . Producing power to help with on peak demand .
Kind of like charging & discharging a battery .

God bless
