Maintenance scheduled for Monday, 21 september, 2020
In order to continuously improve our services, we are planning a maintenance of this website on Monday 21/09/2020 from 9am to 6pm, during which brief interruptions of service could possibly occur. We apologise for any inconvenience this may cause and thank you for your understanding.

Adjusting a connection

Grid users wishing to adjust their connection must notify Elia. How should they go about it?

Any grid user wanting to adjust their connection (to take off more energy or install a new generation unit, for instance) must notify Elia.

In-depth study

Grid users can request an in-depth study to this end. Should adjustment actually prove necessary, Elia will make an offer for an in-depth study based on the regulated tariffs. Otherwise Elia will confirm that an in-depth study is not required and that the requested adjustment is considered a minor modification to the connection. 


The requester selects 'In-depth study' on the connection request form. They must then enter the technical specifications required to conduct the study. Once any attachments have been added, the form is sent to Elia by email. Elia may request any additional information it needs to complete the in-depth study.


The cost of an in-depth study is based on the applicable tariffs. The studies conducted by Elia as part of the connection process are subject to the general terms and conditions, which are applied in a non-discriminatory way.
