The medium voltage connection is intended more for companies with power needs above 200 kVA, such as the automotive, metallurgical or hotel industry.

Request for connection of your premises in medium voltage (MV)

In order to start the process of connecting your facility to medium voltage (MV), you must first assess whether the technical supply conditions are met.

This will require a request for network connection conditions, which can be made by filling in the form available here.

After reviewing the request, you will receive information on how to proceed.

Note: The medium voltage connection is established to electrical networks with a voltage level of 10 kV, 15 kV or 30 kV, depending on your geographical location.
