I am excited that Nexans has been selected as the supplier by Red Eléctrica, the electricity transmission system operator for the Mallorca-Menorca 3 interconnection project. This announcement was made on October 22 2026. The purpose of the Mallorca-Menorca 3 project is to secure electricity supply and strengthen the power network in the Balearic Islands.
The plan is to construct a 132‑kilovolt (kV) high‑voltage alternating‑current cable between Mallorca and Menorca. This cable will run under the sea and underground. The aim of the cable is to provide a reliable electrical link between the two islands.
According to the tender process Nexans will participate in an engineering phase. This phase will focus on identifying the details required for an engineering, procurement, construction and installation (EPCI) contract. The actual work, on the Mallorca-Menorca 3 project is expected to begin in mid‑2027 after the contract is finalized.
Red Eléctrica, which is a part of Redeia manages electricity transmission. Runs Spain’s power systems. This new interconnection is part of their effort to make electricity supply more dependable across the Balearic Islands.
Nexans brings experience in power transmission and cable systems to the project. Their selection shows how important specialized cable makers are in building the infrastructure needed to connect power networks improve how flexible the system is and help with the shift to cleaner energy.
This project comes after planning and environmental studies done by Red Eléctrica. The new cable connection is meant to improve electricity supply, on Menorca and reduce the island’s need to use power plants that burn fuel.
Why Subsea Power Cables Matter for Energy Infrastructure
Subsea power cables are becoming more important in electricity networks that connect islands, offshore energy facilities and places that’re far apart from each other. These connections allow electricity to move between networks giving operators more choices for balancing how much power is being supplied and how much is being used.
For island communities having connections can reduce their reliance on electricity that is made in one place and can offer ways to get power when individual power plants have problems. More network space can also help operators add energy sources while keeping the electricity service steady and reliable.
These kinds of projects have big engineering problems. Cable systems need to handle conditions the shape of the seabed and the electrical pressures that come with sending power over long distances. Installing the cables testing them looking at the environment and taking care of them over time are all important for making sure everything works well.
The Mallorca-Menorca project shows how transmission infrastructure can help with energy security and with reducing carbon emissions. Its success will depend on engineering clear plans, for building and working together between the company that handles the power lines the company that makes the cables and all the other people involved in the project.
Potential Impact on Japans Energy and Technology Industry
Even though the Nexans announcement is about Spain the project has implications for Japans energy infrastructure sector.
Japans geography makes electricity transmission and grid resilience considerations. The countrys island structure, the fact that most people live in cities and the increasing need to add renewable energy create a need for strong transmission networks and high-tech grid solutions.
Projects like Mallorca-Menorca show how underwater connections can make energy supply more secure in island areas. For Japan similar ideas are relevant when talking about linking power systems increasing the ability to move electricity and helping offshore renewable energy projects.
Japanese companies that make power cables, electrical equipment, grid monitoring tools and industrial engineering solutions could gain from investment in these technologies. There is also a chance for businesses that create systems to monitor conditions, software for predicting maintenance needs and digital tools for handling complicated transmission systems.
Japans power network has different technical, legal and geographic needs compared to Spains. The Mallorca-Menorca project should therefore be seen as an example of grid development from another country of proof of a direct chance, for Japanese companies.
Business Implications for Cable Manufacturers and Energy Operators
The project highlights several commercial considerations for businesses involved in electricity transmission.
Demand for infrastructure grows when grid operators expand transmission capacity. Demand for infrastructure may rise for high‑voltage cables, subsea engineering, installation services and related electrical equipment.
Long‑term service opportunities appear because power transmission assets need monitoring and maintenance during their working life. Long‑term service opportunities then create demand for inspection technologies, diagnostic systems and asset‑management services.
Renewable energy integration can give grid operators flexibility when they have stronger interconnections allowing them to handle variable renewable generation. Renewable energy integration however depends on the network capacity and the way the system operates.
Complex project execution involves cable installations that need close coordination between engineering teams, equipment suppliers, contractors and regulators. Complex project execution faces delays, environmental constraints and installation challenges which can change project schedules and costs. For businesses these developments emphasize the importance of combining advanced manufacturing capabilities, with engineering expertise and reliable project delivery.
The Road Ahead for Grid Modernization
Nexans‘ selection for the Mallorca-Menorca 3 project reflects the continuing investment in electricity transmission infrastructure needed to improve network reliability and support the energy transition.

The next phase will focus on working in engineering and getting ready for the future EPCI contract. The expected start of delivery in mid-2027 still depends on the steps in the contract and the way the project moves forward.
In the Japan energy technology sector the lesson is clear: stable electricity networks need more than just extra power generation. In the Japan energy technology sector the power lines, materials, monitoring systems and team efforts all play a part, in keeping the supply safe and reliable.
When countries invest in energy and strengthen their electricity networks specialized cable manufacturers and technology providers will stay key players, in infrastructure development. The Mallorca‑Menorca project shows how focused interconnection investments can make a power system more resilient.
