Pumped hydroelectric energy storage | Climate Technology
Pumped hydro storage uses two water reservoirs which are separated vertically. In times of excess electricity, often off peak hours, water is pumped from the lower reservoir to the upper reservoir. When required, the water flow is reversed and guided through turbines to generate electricity. | Tue, 11/08/2016.

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
