LS Eco Advanced Cables Joint Venture moves to Supply Contract

Global InterConnection Group and LS Cable & Systems are building on their partnership to deliver HVDC subsea cable for the two 1,708km Atlantic SuperConnection cables linking Iceland to the UK.

Having made such significant progress in the development of a world-leading High Voltage Direct Current (HVDC) cable manufacturing facility in the North-East of England, LS Cables & Systems will now take on full responsibility for building and operating the Cable Factory; and delivering HVDC cable to Atlantic SuperConnection.

Our collaborative joint venture has achieved a significant milestone in creating the opportunity for Tyneside to be a global centre of excellence for HVDC cable production, critical to securing the UK supply chain for the energy transition. The LS Eco Advanced Cables joint venture has been pivotal in this achievement: identifying a prime factory site; leading discussions at both local and national government levels; and bringing stakeholders together across planning, construction, and the supply chain. The joint effort has laid the foundation for the UK HVDC cable supply chain to support major energy infrastructure projects, including GIG's flagship Atlantic SuperConnection interconnector between Iceland and the UK. As the project enters its next phase of development, LS Cables & Systems, with its depth of manufacturing facility expertise, is best placed to take the operational reins. Atlantic SuperConnection's cable supply contract will serve as the anchor order for this material investment.

We are proud of what has been accomplished through our collaboration and are excited to continue advancing the HVDC interconnection sector, reinforcing our commitment to sustainable, resilient, and secure energy infrastructure.
