Connecting to our grid

Any producer or customer wishing to connect an electrical facility, to change an existing connection and/or transformer must submit a request for a new connection or for a modification to an existing one.
It is recommended to submit the request as early as possible to allow Elia to begin analyzing the best technical solution. Elia will assess the request based on the information provided by the applicant.

You can connect your facility to the Elia grid if:

• It has a capacity equal to or greater than 25 MVA (for offtake or injection), or
• It has a capacity equal to or less than 25 MVA, but has been refused connection to the distribution network.

If you are an existing grid user, any modification to your grid connection—such as increased energy consumption, the installation of a new generation unit or the replacement of a transformer—must be reported to Elia.

Grid users can request an in-depth study for this purpose. If a modification is deemed necessary, Elia will provide an offer for an in-depth study based on regulated tariffs. If not, Elia will confirm that the requested adjustment is considered a minor modification and that no in-depth study is required.

Note: To ensure non-discrimination, Elia reserves the right to require an orientation study before allowing a grid user to request a detailed study.

How to apply for a study (orientation or detailed study)?

Depending on your situation, you should either apply for a study via the EPIC portal of Elia or use the web application form. 

1. You are an existing grid user (you already have a connection contract signed with Elia): You should use the EPIC portal to request a study offer. 
2. You are a new grid user (no connection contract signed yet with Elia):  You should use the following link to introduce a study request: Connection request
