Training sessions for operators

Operators must be capable of accurately assessing the risks associated with their work and their work environment.

What exactly is an operator?

An operator is a person working on or near an Elia facility, under the supervision of a work leader.

To be able to carry out their work properly, operators must be capable of accurately assessing the risks associated with their work and their work environment and taking the appropriate personal safety measures.

‘Operator’ certificates are issued as confirmation that their holders possess these abilities.

Four certificate types

There are four types of certificate for operators. The certificate type is based on the place in which the operator will work. 

  • GSIS operator
    The ‘General Safety Instructions for working on high-voltage substations (GSIS)’ certificate is for contractors’ employees working in Elia high-voltage substations.
  • GSIL operator
    The ‘General Safety Instructions for working on high-voltage lines (GSIL)’ certificate is for contractors’ employees working on Elia pylons or high-voltage lines.
  • GSIC operator
    The ‘General Safety Instructions for working on and in the vicinity of cables (GSIC)’ certificate is for contractors’ employees working on and near Elia underground cables or working on public roads on Elia’s behalf.
  • GSIO operator
    The ‘General Safety Instructions for offshore work (GSIO)’ certificate is for contractors’ employees working on high-voltage platforms in the North Sea.  

How to obtain certification as an operator

  • Apply to register
    You can register for one of these four services for one or more certificate types 
    • Test on Elia’s premises only: study the course material independently and register for a scheduled test session. This service is free of charge.
    • Test on the contractor’s premises only (min. 20 participants): your employer holds a test session on its own premises; the test is supervised by an Elia examiner. There is a flat fee of €1,500 for this service.
    • Training session + test on Elia’s premises: attend a half-day training session on Elia’s premises and take the test the same day. There is a fee of €150 per participant for this service.

    Click on Register to register for one of these services for one or more certificate types and upload your BA4/BA5 declaration of competence and your photo. (NB: To avoid long processing times, please ensure that your documents are in order before registering.)
     
    Due to the COVID-19 safety measures in place, companies are urged to put their employees in groups of no more than 12 people wherever possible.
     
    The test may be taken in the following languages: French, Dutch, English, German, Polish, Portuguese, Turkish, Bulgarian, Romanian and Italian.
     
    The registration deadlines are as follows: one week in advance for tests on Elia’s premises, two weeks in advance for training sessions on Elia’s premises and one month in advance for tests and/or training sessions on the contractor’s premises.
     
    The participants’ names and/or the tests for which they are registered can only be changed on the website, and only if the registration for the relevant session is still open. Once registration for the session is closed, changes can no longer be made.

  • Test/training session

    As mentioned on the main page, your registration is final as soon as you receive confirmation that you have registered. Please bring the following to your test/training session:

    • your identity card or, if you are not Belgian, your passport;
    • a pen or pencil;
    • confirmation of your registration;
    • a face mask, which you must wear at all times on the Elia site.

    Please go to reception no more than 10 minutes before your appointment time, while also taking care not to be late.
    Furthermore, it is extremely important that you:

    • keep a safe social distance from all other people on the site;
    • disinfect your hands regularly, as indicated on the site;
    • not attend if you feel unwell or have symptoms of COVID-19;
    • leave the building and site immediately after your test or training session.

  • Pass criteria

    To be certified as operators, participants must score at least 7/10 on the test.

    Participants who do not score at least 7/10 must wait two weeks to be able to retake the test. This is because we believe that participants will need two weeks to work through the material again.

    Participants who pass the test will be issued with a badge within one week (if they took part in a test session on Elia’s premises) or three weeks.

    This badge will enable them to access Elia’s facilities and carry out work in or on these facilities. It is valid for two years.


  • Basic knowledge

    Anyone seeking certification as an operator must have the level of basic knowledge required for operators of the risks present in Elia facilities and the prevention measures used to address them.

    Depending on the type of work to be carried out, this may require knowledge of the risks and prevention measures associated with work in high-voltage substations (GSIS), work on or near cables (GSIC), work on overhead lines (GSIL) or work offshore (GSIO).

    The documents and presentations for each profile can be found under ‘Course material’.
