Electricity Supply Free Market

Find out more about the liberalisation of the electricity market

What is the Electricity Supply Free Market? 

The electricity market has been fully liberalised since 1 July 2007. Before 1 July 2007, domestic customers had to contact their local distribution company for a supply contract, commercial services or any other matter concerning electricity.

Liberalisation was introduced to Italy with the Bersani Decree (Legislative Decree no. 79 of 16 March 1999).

The decree implemented the indications of the earlier EU Directive no. 92 of 1996 on the creation of the Single Energy Market, initiating the process of liberalisation of the production, import, export, purchase and sale of electricity.


What are the energy cost components?

The cost of supplying energy is made up of four components:

  • one is set by the Authority for Electricity, Gas and the Water System to cover energy transport and distribution services (network services) and so-called general system costs to cover the charges introduced by various laws and ministerial decrees (the most relevant of which are Legislative Decree no. 79/99, the Decree by Minister of Industry of 26 January 2000, and Laws no. 83/03 and 368/03);
  • another is the cost of marketing, established by Enel Energia to cover the costs incurred by the sales company to supply its customers;
  • a third component is the cost of supplying the energy, which is set by Enel Energia to cover the cost of acquiring the electricity;
  • the final component consists of taxes: VAT and excise duty.

How the energy supply for Free Market works

Since the energy market has been liberalized, all end customers can choose their supplier. The local distribution company is left with the management of the energy distribution service under concession and according to the rules and tariffs set by the Regulatory Authority for Energy, Networks and the Environment (ARERA). The liberalization of the electricity market has allowed suppliers to offer a new range of products and services to better satisfy their customers.
