The seller within the framework of the supply contract with the final customer may be defined as the counterparty who guarantees: the supply at the conditions established by the contract; the billing; and customer assistance. The seller may not be a direct producer, and may not be a counterparty who purchases electricity or gas as a wholesaler to then resell it to the final customer.
The Ministry of Economic Development (MSE) authorises the connections for the distribution companies in relation to the distribution activity, namely, the transport and transformation of medium- and low-voltage power into electricity for delivery to the final users. The distributors are responsible for user connections (regardless of whether the users are regulated or unregulated) and connections of custom service. The distributors operate under a system of incentives and penalties, in order to ensure standard levels of service quality and continuity on their networks. The largest distributors are also required to undertake projects in relation to the user’s rational use of energy, in accordance with the objectives set by the Ministry of Productive Activities (Ministerial Decree of 20 July 2004) for the reduction of primary energy consumption.
È la persona fisica o giuridica che produce energia elettrica indipendentemente dalla proprietà dell’impianto di produzione (Art. 2 comma 18 D. Lgs 79/99). L’energia elettrica in Italia viene generata in parte attraverso fonti non rinnovabili come il carbone, il petrolio e il gas naturale e in parte grazie all’impiego di fonti rinnovabili. Il produttore può generare energia per autoconsumo, cioè per coprire le proprie necessità, o per venderla sul mercato.
Wholesalers are physical or legal persons who purchase and sell electricity, without exercising any activity of production and distribution within the European Union.
Compensation Fund for the Electricity Sector (CCSE)
The entity has the responsibility, for both electricity and gas, of collecting tariff components, and managing the disbursement of public subsidies, with the aim of ensuring the operation of the systems in conditions of competition, security, and reliability. The entity is also responsible for conducting technical inspections and accounting audits of the regulated entities (such as distributors, and sellers of electricity and gas).
Customers in the unrestricted market
These customers are final users who have the option of freely choosing their supplier and have elected to exercise that option. They are not subject to regulated tariffs, except for the transport, measurement and dispatch components, and they may acquire energy in various ways. As from July 2007, all final customers were free to leave the protected market and to move into the unrestricted market.
These are final retail customers (households) or small businesses, provided that when the business draws power as a small business, it does so through a low-voltage network. These customers choose to remain under the protected system, and to pay the tariffs regulated by the AEEGSI and not to transfer to the unrestricted market.
Ministry of Economic Development (www.sviluppoeconomico.gov.it) (MSE)
In addition to steering the activity of the AEEGSI and the energy sector in general, the Ministry of Economic Development grants concessions to distributors, issues the related conventions, and defines the strategy for the security and the cost-revenue breakeven of the national energy system. It also issues the Environmental Impact Assessment (“VIA”) for thermoelectric plants with thermal power in excess of 300 MW, on the basis of the streamlined procedure implemented under Law No. 55 of 9 April 2002.
Italian Regulatory Authority for Electricity Gas and Water (AEEGSI)
