Question 30

Write a Definition Of Kinetic-Pumps Storage System?

Answer 30

A kinetic-pumped storage system is a fast-acting electrical energy storage system Which Supplies Energy To The National Grid When The Demand Is at its Lowest.

Question 31

How Does The Pump Storage System Work?

Answer 31

• It Works By Having 2 Reservoirs and a Hydroelectric Dam System.

Question 32

What Happens At Night at The Storage System and What Happens To The Cost?

Answer 32

During night Time excess electricity is produced by other electrical energy stations, meaning the cost of the electricity is much lower, so a kinetic-pump plant will pump the water from a lower reservoir up to a higher reservoir.
