Transmission System Operators (TSOs) Elia (Belgium) and Energinet (Denmark) have signed agreements for what could be the first undersea connection between two artificial energy islands which will be able to exchange power between the two countries and at the same time transport electricity from offshore wind farms to the mainland.

The 600 km project, named Triton Link, included a preliminary feasibility study which was carried out over the past few months. According to the project partners, it has demonstrated that the project is both socioeconomically and technically feasible.

The TSOs have announced the signing of a new cooperation agreement between the two system operators.

Furthermore, a partnership agreement was also signed by the Belgian and Danish Energy Ministers, Tinne Van der Straeten and Dan Jørgensen, respectively.

"Triton Link will be an important first that will determine the further development of the European offshore electricity grid. For the first time ever, two artificial energy islands will be electrically connected via a cable that not only exchanges power between the two countries but also connects to large-scale wind farms in the remote North Sea. This technological feat will enable Elia Group, Energinet and all the companies involved to gain an innovative global lead," commented Chris Peeters, CEO Elia Group

Elia and Energinet will now further flesh out their plans and map out possible routes for the project, including its landing points and the locations of converter stations. Based on these conclusions, a final decision will be made regarding investment in and the implementation of the project. The construction of Triton Link will take approximately four years and is due to be completed around 2030.

Energinet is also currently working on an additional submarine cable with Elia Group's German subsidiary 50Hertz. The two system operators previously signed a memorandum of understanding (MoU) to prepare for a second hybrid interconnector in the Baltic Sea. The cables will also be connected to offshore wind farms via a link to Denmark's Bornholm Energy Island. The TSOs announced today that the project is now also being further examined and developed.

"I see the cooperation agreement as a big step forward towards Danish energy islands becoming a reality and with huge gains for a greener Europe. Today's agreements show not only that the whole idea of energy islands and connections to several countries is a good idea, but also that the countries are very keen to implement the huge offshore wind projects. It's a big day that brings the energy islands with neighboring countries one important step closer," said Thomas Egebo, CEO Energinet
