How does hydroelectric power generation work?

The production of electricity from green sources continues to grow. Among these, hydroelectric power remains the most widespread, with innovative plants around the world, such as pumped storage plants, which act as real rechargeable "water batteries".Currently, hydroelectric plants are categorized into three main types. Let''s explore each in more detail.

Electricity production

Wind and solar power are intermittent; electricity can only be generated when the energy is available. The same applies to run-of-river power plants and small-scale hydropower plants. However a number of the large run-of-river power plants in Norway lie downstream of storage hydropower plants in the same river system, and this influences their production patterns.
