First Phase of Cabling Completed for NeuConnect Interconnector Project Linking UK and Germany

NeuConnect Interconnector Marks Key Milestone with First Phase Completion
The €2.8 billion NeuConnect Interconnector project has reached a significant milestone with the successful completion of its initial phase of cabling. This project, set to be one of the world’s largest energy interconnectors, aims to establish the first direct electricity transmission link between the UK and Germany. Backed by major global investors such as Allianz Capital Partners, Meridiam, Kansai Electric Power, and TEPCO, the NeuConnect interconnector will play a crucial role in enhancing energy security and supporting the integration of renewable energy into both countries’ power grids.

Connecting the UK and Germany: A 725km “Invisible Energy Highway”
The NeuConnect interconnector will run 725 kilometers, linking converter stations at the Isle of Grain in Kent (UK) and Wilhelmshaven in northern Germany. The interconnector will enable the bidirectional flow of 1.4GW of electricity, enough to power up to 1.5 million households, providing a stable energy supply between the two nations. The project is part of a broader effort to integrate renewable energy and strengthen energy security in both markets. The interconnector will also enhance the UK’s ability to export excess renewable energy to Germany, contributing to the decarbonization goals of both countries.

Phase One Cabling Led by Prysmian Group
The first phase of cabling work, involving the installation of 56 kilometers of onshore and subsea cables, was carried out by Prysmian Group, the lead contractor. The subsea cables, laid in UK waters, are carefully buried beneath the seabed to minimize environmental impact. Prysmian’s Cable Enterprise vessel was used to lay the subsea cables, ensuring they were safely installed to protect the marine environment. In addition, a series of underground ducts were constructed along the Isle of Grain coastline to facilitate the onshore connection of the cables.

Construction Progress and Timeline for Completion
Construction of the NeuConnect project began last year, with foundation works for the UK converter station underway. Piling operations for the German converter station are also in progress. While the first phase of cabling has been completed, the work is far from finished. The extensive cabling program will continue in 2025, extending through UK, Dutch, and German waters, with full completion of the interconnector expected by 2028. The NeuConnect project will utilize high-voltage direct current (HVDC) cables, rated at 525kV, to establish a secure and efficient energy connection between the two countries.

Looking Ahead: A Vital Link for Energy Transition
Julia Prescot, Chair of the NeuConnect project, noted that completing the first phase of cabling is a critical step in the development of the interconnector. However, she emphasized that there is still much work to be done to complete the full 725km link. Collaboration with industry partners and continued focus on the scale of the project will be essential for ensuring its success. Once operational, NeuConnect will provide long-term benefits for both the UK and Germany by enhancing energy security, supporting renewable energy integration, and contributing to the energy transition goals of both countries.
