The above-mentioned updated versions of the Technical Rules fully replace the previous versions published on GME’s website.

GME informs market participants that, as of today, with the publication on its website, the updated version of the Natural-Gas Market Rules (MGAS Rules) will enter into force.

The MGAS Rules have been amended to provide that even non-EU Third Countries - having signed an intergovernmental Solidarity agreement with the Government of the Italian Republic - may request the activation of solidarity measures within the Market for the Management of Voluntary Solidarity Measures (hereafter MVS), as established in the Agreement between Snam Rete Gas and GME, approved by ARERA with its Resolution 4/2026/R/gas, concerning the information flows necessary for the operation of the MVS.

Starting from 15 October 2025, GME will make available a new channel for accessing its market data (published in the “Results” section of its website www.mercatoelettrico.org): an API (Application Programming Interface) Service.

The new channel will initially operate alongside the current FTPS channel, which will remain active during for a further transitional period only for already registered users.

The final decommissioning of the FTPS channel will be announced well in advance to allow interested users, already registered with the FTPS, to migrate to the new system in a gradual and smooth way.

To request authorisation for data access via the API Service, the applicant must submit the documents listed at the following link, in accordance with the procedures and within the timeframes indicated in the API User Manual.

All interested users are invited to consult the API Service access procedure and related technical documents, available at this link.

For queries about the authorisation procedure, please contact SupportoAPI@mercatoelettrico.org.

To receive technical-IT support, please contact Sistemi@mercatoelettrico.org.

Following some reports received by telephone and email to Gestore dei Mercati Energetici S.p.A. ("GME"), it seems that these telephone calls are made by a supposed "GME Office" and/or so-called GME operators, regarding proposals to change the electricity and/or gas supplier due to increases in cost of energy, not properly specified, or problems in the current supply, which were followed, in some cases, by emails with similar content.

It should be remembered that GME is completely unrelated to the event mentioned above. We would like to clearly state that we do not provide, in any way, commercial services such as those described above. Furthermore, we do not use communication methods with our clients such as those outlined above.

When in doubt, we always suggest to make sure of the above by contacting your current electricity and/or gas supplier according to the contact methods made available by the same. In any case, we suggest to avoid any possible follow up about proposals such as those highlighted above, in order not to face any unpleasant inconveniences.
