  2. How It Works

  3. Working with it • Between 1976 and 1982 at Dinorwig ,in North Wales a massive project was built and there’s still a little to see as you drive by. Most of it is deep inside the mountain.

  4. Pumping it back up • At night water is pumped to the top reservoir when demands for power across the country are low.

  5. The Headgates • When there’s a sudden demand for power, the head gates/huge taps are opened, the water is then rushed down the tunnels to drive the turbines and they drive powerful generators. The pump/turbines are handy for two things they can pump the water from the bottom reservoir to the top, and to generate power or electricity.

  6. The Advantages of pumped storage • Without some means of storing energy for quick release, we’d be in trouble. • It has little affect on the landscape. • It provides power faster than any other power station. • It gives no pollution or waste.

  7. The Disadvantages of pumped storage • It is very expensive to build. • Once it’s used, you cannot use it again until you’ve pumped the water back up. • But the industry is very good at predicting when the surges in power demand will happen, so good planning can get around this problem.

  8. Is it renewable? • It’s not really a power station, but a means of storing energy from other power stations, so the question doesn’t apply

  9. More Facts About Dinorwig • When water is pumped up to the top reservoir called Marchlyn Mawr they are storing gravitational potential energy in it, the greater the height, the more energy is stored. • The water falls 600 meters on its way to the turbines, so it’s under a great deal of pressure when it arrives. For this reason, the tunnels are lined with steel at the bottom end.
