Cable deployment enters a key stage for record interconnector cable project

Deployment of Nexans’ XLPE cable for the Celtic Interconnector, which will become the world’s longest subsea XLPE interconnector at 575 km, has entered a crucial installation phase with completion now targeted for 2028. The €1.6 billion project directly links the Irish and French grids and is recognized as a Project of Common Interest by the EU. Land and sea works, including converter station construction and cable burial, are well underway, though commissioning was delayed from 2027 to 2028 due to the scale and complexity of marine cable-laying and system integration. The project will enable Ireland’s first direct energy exchange with Europe, supporting 700 MW capacity to power about 450,000 homes and enhancing renewable energy integration. More than €530 million was provided through EU grants for this strategic energy venture.
