This new interconnection consists of an underwater 132 kV double circuit link circuit between the islands of Ibiza and Formentera, which connects the Torrent substation, in Santa Eulària des Riu, and a new substation built in Formentera, in the Es Ca Marí industrial area. 

The new interconnection between the islands of Ibiza and Formentera will represent a giant leap in the guarantee of supply on both islands, especially in the latter (the smallest island), as it will enable 100% coverage of the demand at all times under safe conditions for the system, thus minimising the need for local generation and, therefore, reducing costs for the system and favouring the energy transition through the equivalent reduction of CO2 emissions.
