Notices and Announcements

Gestore dei Servizi Energetici – GSE S.p.A. has informed GME that the Certigy platform, managed by GSE, will be unavailable from 18:00 on 8 December 2025 to 10:00 on 9 December 2025. This suspension is necessary to implement, within the platform, the new types of GOs in the gas sector, defined by GSE in compliance with article 15 of Ministerial Decree no. 294 of 7 August 2024 (“Ministerial Decree on Sustainability”). These new types of GOs will replace those applicable so far, as shown in the following table:

As a consequence, throughout the duration of the unavailability of GSE’s Certigy platform, GME’s P-GO platform will be temporarily suspended and will become available again at 10:01 on 9 December 2025.

The P-GO will be also updated to incorporate the provisions referred to in the above-mentioned Decree.

Hence, interested market participants may again submit requests for registration of bilateral transactions on the PB-GO from 10:01 on 9 December 2025.

Please note that, with the introduction of the new types of GOs in the GAS sector, the requests for registration of bilateral transactions - present on the PB-GO system, still awaiting processing upon suspension of the P-GO, and covering the previous GOs in the gas sector - will be automatically updated (as indicated by GSE) by replacing the previous type of GAS GO with the corresponding new type of GAS GO with the “CNGandLNG” label.

With regard to the MGO, the new configuration of the platform will be available for market participants upon the session planned for 11 December 2025.

Upon the reinstatement of the P-GO platform, GME will communicate the updated versions of the Technical Rules incorporating the new types of GOs in the GAS sector.
