Production of electricity from such plants takes place according to a regime whereby, for the first eight years, the certification of production from renewable sources (green certificates) has a value, by right, of 100 MWh. Green certificates can be sold as a means of ensuring compliance with the obligation to introduce energy from renewable sources.

Like the other certificates, green certificates have their own market, the Green Certificate Market.

     
  • Greenhouse effect (Energy glossary)
