Extranet / Electronic Submission of studies


EDA THESSALONIKI-THESSALIA SA would like to welcome you to the new online service for the submission and handling of the internal gas installation file.

The Extranet, developed and implemented by EDA THESSALONIKI-THESSALIA SA is an online service aimed at streamlining procedures, providing natural gas professionals with high quality services.

This pioneering online application deals with the process of handling the gas file and informing professionals completely quickly and easily, thus saving time. The application includes the following options:

  • electronic submission and handling of all the documentation included in the natural gas file;

  • provision of information on the progress and current stage of the gas file and of the internal installation inspection and activation schedule. 

    The following are the requirements for accessing the above service:

    A. to request a username and password from the Gas Distribution Company;
    B.    to obtain a digital certificate for the user to ‘sign’ the digital files.

    To access the Extranet, an engineer and/or supervisor should apply to the Gas Distribution Company using the template obtained from the Internal Installations Department.

    After the application is examined, the username and password for the Extranet will be provided and the user will be able to completely manage the internal gas installation file, in accordance with the Extranet user manual and explanation of functions.

    To upload and transmit the files via the application, a digital signature is required (which serves in place of a handwritten signature according to Presidential Decree 150/2001), based on a recognised certificate and created by a secure signature creation device (SSCD).

The manual attached  describes all the steps to be taken by a final user of the www.ermis.gov.gr portal to obtain digital certificates from the Hellenic Public Administration Certification Authority (HPARCA) using the ‘ERMIS’ portal. The manual covers all the issues involved, from user registration on the portal to visiting a citizen service centre (KEP) to have the request approved.
