How hydroelectricity works

Hydroelectricity is produced in a hydroelectric power station.

  • It is a flexible form of energy, with dams and lakes forming electricity production reserves that can be called into action quickly.
  • "Run-of-the-river" hydroelectricity is produced by power stations without reservoirs that use the rate of flow of a river to continuously produce electricity.
  • The power station turns the force of the water into mechanical energy via a turbine that drives an alternator to produce electrical energy.
