Rómulo 2 (Mallorca–Ibiza) is the second subsea electricity interconnection implemented by Red Eléctrica de España (REE) to link the Mallorca and Ibiza/Formentera island subsystems. The project was developed to eliminate the energy isolation of the islands, improve quality and stability of supply across the Balearic system, and reduce reliance on...

28 Oct 2019Financial Other
Red Eléctrica de España reported that the Rómulo II Mallorca–Ibiza undersea interconnection, a 118 km AC submarine cable project linking the islands’ grids, represents an investment of over €215 million, highlighting it as a major capital project that delivers strong CO₂-equivalent emissions reductions for the Balearic system. Earlier communication from the company described total investment for the Rómulo 2 project at €225 million, reflecting the overall scale of committed capital for the Mallorca–Ibiza electricity link.
€215M
2015First PowerStale
Red Eléctrica de España planned for the Rómulo 2 Mallorca–Ibiza 132 kV AC submarine interconnection to enter service for a trial operating period in 2015, following installation of the double-link, 126 km three-phase cable system connecting the Bay of Talamanca (Ibiza) with the Bay of Santa Ponsa (Majorca) to improve stability and resolve the energy isolation of Ibiza and Formentera.
2015Cable Installation CompleteStale
Prysmian Group, contracted by Red Eléctrica de España for the second circuit of the Mallorca‑Ibiza interconnection associated with the Rómulo system, planned to complete installation and protection of its 132 kV HVAC submarine and land cable system in 2015. The project involves 115 km of submarine cable and 8.6 km of land cable, with deep‑water marine installation (up to 750 m) carried out by Prysmian’s vessel Giulio Verne, enabling Ibiza’s integration into the peninsular transmission system via the existing Romulo link.
12 Nov 2014Early Development Other
On 12 November 2014, Red Eléctrica publicly presented the Rómulo 2 Mallorca–Ibiza submarine electricity interconnection project at the Pueblo de Jesús Cultural Centre, outlining the plan to install a 126 km, double‑link 132 kV AC submarine cable (including 118 km underwater) between Talamanca Bay (Ibiza) and Santa Ponsa Bay (Majorca) and confirming a total project investment of €225 million ahead of the start of cable‑laying works.
12 Nov 2014Survey Other Start
By November 2014, Red Eléctrica had started excavation and conservation works on an archaeological site located within the premises of the Torrent substation in Ibiza as part of the environmental requirements for the Majorca–Ibiza interconnection (Rómulo 2). The company committed over 700,000 euros to this archaeological project within a broader 2.2 million euro programme of preventive and corrective environmental measures designed to minimise the new link’s impacts on natural habitats and cultural heritage.
2014Cable Supplier SelectedStale
Under a contract from Red Eléctrica de España for the new high-voltage submarine link between Mallorca and Ibiza (Rómulo 2), Nexans planned installation and commissioning of a 132 kV AC submarine cable system between 2013 and 2014, covering about 115 km of subsea cable plus associated high-voltage land cables to integrate Ibiza into the peninsular transmission system via Mallorca.
22 Apr 2013Cable Supplier Selected
On 22 April 2013, Prysmian Group announced it had been awarded by REE a contract worth approximately €85 million for the second circuit of the Mallorca–Ibiza interconnection (Rómulo II), covering the turnkey design, supply and installation of a 132 kV HVAC cable system rated 118 MVA with about 115 km of submarine cable and 8.6 km of land cable plus associated fibre optics, enabling full integration of Ibiza into the peninsular transmission system via the existing Romulo link.
Date TBDCable Installation Start
Red Eléctrica de España announced that it would soon begin laying the submarine cable for the Rómulo 2 electricity interconnection between Majorca and Ibiza, using the cable‑laying ship Skagerrak to install a 132 kV AC three‑phase cable from the Bay of Talamanca (Ibiza) to the Bay of Santa Ponsa (Majorca). This marks the start of offshore cable installation for the double‑link interconnector, designed to connect the Majorca‑Menorca and Ibiza‑Formentera systems and integrate them with mainland Spain.
