The Marmora Pumped Storage Design

Pumped storage is storing

and generating energy

by moving water between

tworeservoirsofdifferent

elevations.

Water is pumped up when

electricityisavailable/cheap,

and run down through

turbines when there is

demand/value.

In modern facilities the

pump/motorandtheturbine/

generator are the same units.

Why Not?
