Market participants are hereby informed that with Decree no. 0000257 of the Ministry of Ecology Transition (MiTE) of 22/06/2021, published on the MiTE website, the amendments to the Integrated Text of the Electricity Market Rules were approved (hereinafter: ME Rules), functional to the integration of the Italian market with the Single Intra-Day Coupling (SIDC) and at the start of the project Cross Border Intraday (XBID) on Italian borders, pursuant to the provisions of EU Regulation 2015/1222 (hereinafter: CACM Regulation).

In particular, the amendments approved by the afore-mentioned provision provide that energy trading on the intraday market will take place:

i) according to the continuous trading method, as part of the XBID project;

ii) according to the auction trading method, in the context of Complementary Regional Intraday Auctions (CRIDA), pursuant to the provisions of Art. 63 of the CACM Regulation and ARERA resolutions no.174/2019/R/EEL and no.210/2019/R/EEL.

In this regard, it should also be noted that the operational integration of the Italian market within the EU SIDC entailed the need:

• to adjust the limits on transaction prices (so-called "clearing price limit"), in the context of the day-ahead market (MGP) and the intraday market (MI), in order to implement the provisions, respectively, of the "ACER decision no 04/2017" and of the "ACER decision no 05/2017" concerning the harmonisation of "Maximum and minimum clearing prices for single day-ahead and intraday coupling";
• to introduce a specific Nomination Platform (PN) within the ME, pursuant to the provisions of ARERA resolution no.350/2019/R/EEL, aimed at allowing the possibility of adopting a negotiation by zonal portfolios in the MI-XBID continuous trading sessions, as well as for the management of settlement of the balance between the commercial trading position of the portfolio and the quantities nominated on that platform.

The updated version of the ME Rules, as approved by the afore-mentioned Decree, is made available below for information purposes only.

The amendments to the ME Rules will become effective on the trading day 21 September 2021 (i.e. Go-live date), as indicated in the press release of the European SIDC project, available at the following link.

It is therefore understood that, until the Go-live date indicated above, operation of the ME will continue to be regulated by the provisions in force published in the specific sections of GME's website.
