On 17 July 2025, a multi‑stakeholder working group comprising the Government of the Balearic Islands, Spain’s Ministry for Ecological Transition and the Demographic Challenge, the Consell de Mallorca, Alcúdia Council, Red Eléctrica and the local residents’ platform reached unanimous agreement on a new onshore route for the second Peninsula–Balearic Islands link. The agreed alternative route starts from the Sa Ferradura landing point, follows the Camí de Salou, the MA‑3460 road and an existing forest track on Puig de Sant Martí to the Na Lloreta industrial estate near the existing Sant Martí 220/66 kV substation; Red Eléctrica formalised this alignment in an updated project and environmental impact assessment submitted to the ministry, reducing passage through residential areas and aligning the route with technical and environmental constraints.
In September 2024, Red Eléctrica submitted the projects for the second Peninsula–Baleares electrical interconnection, including associated substations, converter stations and the submarine DC link, to the competent Spanish authorities, initiating the public information procedure and the administrative and environmental evaluation for the scheme.

On 19 September 2024, Red Eléctrica announced that the project for the second electrical interconnection between mainland Spain and the Balearic Islands (Peninsula‑Baleares 2 / COMETA 2) had entered its public consultation and administrative and environmental evaluation phase. The consultation, overseen by the Directorate General of Energy Policy and Mining of the Ministry for the Ecological Transition and the Demographic Challenge, invites comments from administrations, institutions, organisations and individuals on Red Eléctrica’s preliminary proposal, including the Sa Ferradura landfall area and the new Sant Martí converter station near the existing 220/66 kV substation.
On 31 July 2024, Prysmian announced it had received a Letter of Award from Red Eléctrica for the Peninsula–Baleares 2 interconnection, designating Prysmian as the preferred supplier to design, install, test and commission two 250 kV mass‑impregnated HVDC single‑core cables plus fibre optic cables for the new Mallorca–Spanish mainland link. The Letter of Award grants Prysmian and Red Eléctrica an exclusive negotiation period for the full contract, with signing anticipated by the end of 2024, for a project valued at more than €0.5 billion that will reinforce the Balearic Islands’ electricity supply and demand coverage.
On 29 July 2024, a working group comprising Spain’s Ministry for the Ecological Transition and the Demographic Challenge, the Government of the Balearic Islands, Alcudia City Council, the Mallorca Council, the local residents’ platform, and Red Eléctrica was established to develop an optimal onshore cable route for the second Peninsula–Balearic Islands HVDC link (Peninsula-Baleares 2 / COMETA 2), aiming to agree a technically, socially, and environmentally viable land corridor to be reflected in the project and its environmental documentation.
The second Peninsula–Balearic Islands HVDC link (Peninsula‑Baleares 2 / COMETA 2), connecting the Fadrell converter station in Castellón with the new Sant Martí converter station in Mallorca, was included in Spain’s 2021–2026 Electricity Transmission Grid Plan approved by the Spanish Council of Ministers, designating it as a strategic transmission project expected to more than double the benefits of the first interconnection, cover around 65% of Balearic electricity demand and reduce CO₂ emissions by about 905 kt per year.
The second Peninsula–Balearic Islands HVDC interconnection (Peninsula-Baleares 2 / COMETA 2), connecting the Fadrell converter station in Castellón with the new Sant Martí converter station in Mallorca via a 2×200 MW, ~400 km submarine-underground link (around 390 km subsea), was designated as part of Spain’s 2021–2026 Electricity Transmission Grid Plan approved by the Council of Ministers, recognising it as a strategic transmission project for the Balearic system and framing its development within the national grid expansion programme.
