The high voltage connection is intended for companies typically with installed power of more than 10 MVA, supplied at a voltage level of 60 kV.

The high voltage connection is made from the 60 kV network to the substation of the requestor, under conditions to be defined by E-REDES. There may be two types of connection: antenna or direct connection and ring or π connection.

Note: Connections to an existing branch line (T-connection) are not allowed.
