Licence: Inclusion of Ibiza–Formentera 132 kV interconnection in national Electrical Plan
Spain’s Ministry for the Ecological Transition and the Demographic Challenge (MITECO) included the 132 kV Ibiza–Formentera interconnection, including the new Formentera substation, in the national Electrical Plan, integrating this submarine link into the country’s official electricity transmission planning framework.
27 Oct 2025Operations Other
On 27 October 2025, Red Eléctrica reported that the 132 kV Ibiza–Formentera interconnection, in service since June 2023, together with local photovoltaic generation, was now covering 100% of Formentera’s electricity demand under safe operating conditions, enabling the decommissioning of the Es Ca Marí diesel turbine and eliminating CO2 emissions from power generation on the island.
9 Jun 2023Commercial Operations Full Power
Red Eléctrica (Redeia) commissioned the new 132 kV HVAC double‑circuit submarine electricity link between Ibiza’s Torrent substation and the new Formentera substation on 9 June 2023, bringing the interconnector into full operational service six months ahead of schedule and in time to secure summer peak demand on both islands. The €96 million link, in service since June 2023, now reliably covers 100% of Formentera’s electricity demand under safe operating conditions and integrates the island into the wider Balearic and Spanish mainland power system.
9 Jun 2023Cable Installation Complete
By 9 June 2023 Red Eléctrica had completed construction of the new Ibiza–Formentera inter-island electricity link in a record 21 months, including the expansion of the 132 kV Torrent substation on Ibiza, construction of a new 132 kV substation on Formentera, 5.2 km and 4.8 km of underground land cables on each island, and a 27.1 km subsea cable section.
Jun 2023Onss Commissioned
In June 2023 Red Eléctrica commissioned the new 132 kV Formentera GIS substation, which forms the on-island connection point for the Ibiza–Formentera submarine link and is part of the €96 million 132 kV interconnection that has been in operation since that month, enabling Formentera’s electricity demand to be supplied securely from the wider Balearic system and local renewables.
30 Jan 2023Construction Other
By 30 January 2023 Red Eléctrica had completed the enlargement of the existing 132 kV Torrent GIS substation in Santa Eulària des Riu, Ibiza, creating the Ibiza connection point for the new Ibiza–Formentera 132 kV submarine link and reinforcing the island’s transmission grid, with subsequent works focusing on completing the rest of the interconnection.
30 Jan 2023Cable Installation Complete
By 30 January 2023 Red Eléctrica and Prysmian had successfully completed the laying and burial of the submarine section of the new 132 kV double‑circuit Ibiza–Formentera electricity link, finishing installation of the three‑core HVAC cables along the 27 km seabed route between the islands.
30 Jan 2023Cable Landfall Complete
By 30 January 2023 the horizontal directional drilling works for the Ibiza–Formentera link’s landfalls had been completed, with underground bores executed at Sa Punta in Talamanca Bay (732 m) on Ibiza and at Penyal des Vi (529 m) on Formentera to connect the subsea cables to the onshore sections while minimising environmental impact on Posidonia oceanica meadows.
30 Jan 2023Offshore Site PreparationStale
After announcing completion of subsea cable laying on 30 January 2023, Red Eléctrica indicated that the next phase of the Ibiza–Formentera project would focus on offshore site‑protection works, adding further protection measures and cable anchoring systems to safeguard the installed marine infrastructure.
9 Jan 2023Offshore Construction Start
On 9 January 2023 Prysmian Group’s cable‑laying vessel Cable Enterprise started offshore construction for the new Ibiza–Formentera submarine power link, commencing marine works under Red Eléctrica’s project to install two 132 kV interconnection circuits between the islands.
