What is Pumped Hydro and how does it work?

Pumped hydro – also termed Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES) – is technically classified as stored energy. It is not quite a battery, because it does not involve a chemical process. Water is pumped from a lower elevation to a higher elevation and stored in a reservoir at higher altitude.
