About the project

Red Eléctrica de España awards Nexans with a turnkey contract worth around 50M Euros to manufacture and install an interconnection cable between Majorca and Menorca. The interconnection project will strengthen the security and quality of supply on both islands and will allow greater integration of renewable energy under safe conditions for the system and greater efficiency of the interconnected systems.

  • The turnkey contract worth around 50 million euros covers engineering, design, supply, installation, and testing of the interconnection.
  • The contract was awarded and approved only 20 days after the Spanish Council of Ministers granted the administrative authorization for construction to Red Eléctrica and declared it as a public utility project.
