05/11/2026 Amendments to Technical Rule no. 01 PCE (Access to the Information System): introduction of authentication via digital certificate GME announces that, as of today, with the publication on its website, the updated version of Technical Rule no. 01 PCE - Access to the Information System will enter into force. The amendments to the Technical Rule introduce a new procedure for accessing the PCE platform and the related Web Service. This new procedure is based on a personal digital authentication certificate issued by a trust service provider listed in the public register (maintained and made available by Agenzia per l’Italia Digitale) and compatible with the PCE Platform. The updated version of Technical Rule no. 1 (i.e. Technical Rule no. 01 Rev. 03 PCE) will fully replace the previous version published on GME’s website. Please note that, in order to allow PCE participants/user an adequate period to align with the new procedure, the Technical Rule also provides that, on a provisional basis, access to the PCE may continue to take place using the userID and password for an additional 150 calendar days from today’s date. After this transitional period, access to the PCE must be performed exclusively by means of the digital certificate. GME further informs PCE participants/users that both the test platform (https://provepce.ipex.it) and the live platform (https://pce.ipex.it) have already been updated to support user authentication via digital certificates.To this end, users may register their digital certificates following the instructions provided in the User Manual published on the homepage of both the test and live PCE platforms.Finally, please note that the digital certificates already used to access GME’s other electricity and/or gas platforms are compatible with the PCE platform. For queries regarding the use of the digital authentication certificate on the PCE platform, please contact GME at the following e-mail address: sistemi@mercatoelettrico.org
