The electricity market, the venue for electricity trading, was established in Italy by Legislative Decree No. 79 of 16 March 1999 ('Bersani Decree'), to transpose the EU Directive on the creation of an internal energy market (Directive 96/92/EC, repealed by Directive 2003/54/EC). The term 'adequacy' refers to the system's capacity to satisfy electrical energy requirements (based on the citizens and companies' request), while complying with requirements on safety and quality of service. Indeed, an electricity system can be considered adequate if it has sufficient resources in terms of production, storage, control of demand and transport capacity to satisfy the expected demand of electricity with a reasonable confidence level. In order to 'measure' the adequacy of the electricity system, we need to analyse all the possible elements that come into play, which depend on: the variability of demand; the availability of electricity generation capacity, whether traditional or renewable; the availability and management of hydroelectric production; the exchange limits of the national transmission network; and the expected contribution from abroad (imports). Each of these factors can be linked to a specific level of uncertainty, which increases as the time frame considered is longer.

The electricity market is divided into:
1. Day-Ahead Market (DAM);
2. Intra-Day Market (MI);
3. Dispatching Services Market (MSD);
4. Trans European Replacement Reserves Exchange (TERRE);
5. Balancing Market (MB).
In the DAM and the MI - also referred to as Energy Markets - producers, wholesalers and end customers, as well as the Single Buyer (AU) and the GSE (Gestore dei Servizi Energetici) buy and sell certain quantities of electricity on a wholesale basis. These markets are coordinated by the Gestore dei Mercati Energetici (GME), and define the balance prices for electricity trading. On the other hand, in the MSD, Terna procures all the resources necessary for the secure management and control of the national electricity system, and thus for the resolution of intra-zonal congestion, for the creation of the so-called energy reserve, and for the real-time balancing of electricity flows on the transmission grid. TERRE is a European platform for the exchange of so-called replacement reserves for balancing electricity. It allows transmission system operators to purchase and activate energy reserves to correct any imbalances in the electricity system. Balancing Market (MB): the set of activities performed by Terna for selecting the offers presented on the Dispatching Services Market to resolve the congestions and establish secondary and tertiary reserve power margins, carried out on the same day as that to which the offers refer.
