Submarine cables to support the Energy Transition

Submarine Cables

Submarine cables to support the Energy Transition

Power generation from Renewable Energy Sources (RES) and network interconnections are two pillars in the ongoing energy transition.


Submarine cables are, and will be, an essential part of this development, both for offshore power generation – where they are used as array cables between, for instance, wind turbines, and as export cables for connecting to the onshore grid – and for interconnections between different systems, countries or price areas, thus supporting the implementation of larger and more efficient electrical grids.

Increased use of insulated cables and greater attention from the scientific community have been recently discussed in a CIGRE article.

As market leader, Prysmian is therefore playing a leading role in the energy transition. The evolution of submarine cable systems in the near and far future will promote further improvements both in interconnectors, where an increased depth of installation will open up new routes in deep-sea waters, and in offshore RES integration, where floating structures for offshore power generation will drive the need for flexible and dynamic cables.

 

 

 

 

The first submarine cable with non-metallic armour, specifically designed for deep-water applications, is now in service between the two Greek islands Evia and Andros. Thanks to this innovative product, Prysmian will be able to perform ultra-deep installations reaching up to 3,000 metres, and to provide its customers with almost all the submarine cable routes they might need.

As the next-generation energy source is likely to be offshore floating wind, Prysmian is also preparing to achieve a leading position in dynamic cables. Leveraging on extensive expertise and experience in SURF applications, Prysmian is able to design and deliver cable systems that can resist the wear and tear of a floating turbine. This type of dynamic cables is already installed, for example, at the Kincardine Offshore Floating Wind Park, and in 2021 will be used by EDF at Provence Grand Large, a floating offshore wind farm project off the coast of France.

 

At Prysmian Group, we are investing heavily in R&D to develop new cable technologies that will help change the way we power the word. We are constantly improving and innovating, offering new solutions that support the development of more sustainable and efficient power transmission and distribution grids.
