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?
