Connecting high-voltage premises

Learn about the conditions for making a high voltage (HV) connection. Learn how to request this connection from the 60 kV network to the substation of an applicant, the secondary electrical distribution network.

You can connect to the high voltage network via overhead lines or underground cables;

It is mandatory to have a high voltage switching station (PCAT) near the substation of the customer with ancillary services for the PCAT remote control, fed by the medium voltage public distribution network;

It must be possible to access the land destined for the switching post via the public road, so the surface use right will always be of E-REDES, if it is not owned by the company.
