Project Update

Ibiza–Formentera Interconnection, Spain [free access]

August 23, 2021

Developers: Red EléctricaEspaña (REE), Spanish transmission system operator

 

Project details and status: The interconnection between the Spanish islands of Ibiza and Formentera includes deployment of two 132 kV links between the new substation under construction in Formentera, and the existing Torrent substation in Ibiza that is in the process of being expanded. It will have an underwater section of 27.15 km and will run at a maximum depth of 62 metres, while the land section is 5.26 km in Ibiza and 4.8 km in Formentera. The entire route of the project is underground and runs almost entirely through publicly-owned areas alongside existing roads, highways and public roads.

 

The project will entail an investment of EUR95.8 million and will aid in strengthening the security of supply for the island of Formentera, currently linked to Ibiza by a 30 kV double-circuit electricity link.

 

REE has signed a contract with the Prysmian Group, for the manufacture and installation of cables for the two circuits. Prysmian will also be responsible for the future laying of the underwater section of the link. REE has also commenced the construction works for the new Formentera substation as well as the enlargement works for the Torrent substation.

In August 2021, Spain’s Ministry for the Ecological Transition and the Demographic Challenge approved the Environmental Impact Statement (EIS) for the interconnection allowingREE to commence construction activities.
