Most of Meridian's electricity is made from the energy of falling water. Our hydro stations generate enough electricity to power around 1.4 million homes each year.
- The water, falling through a pipe called a ‘penstock’, is used to spin a turbine.
- These turbines look like large wheels with wide spokes. The water hits the blades and pushes them to make the turbine spin.
- The spinning turbine spins the generator, which generates the electricity.
- This spinning therefore ‘changes’ the force of falling water into electricity.
It's not possible to store large amounts of electricity. But it is possible to store water in dams.
