Description
Sumitomo Electric Industries is the cable partner in the Siemens Energy–Sumitomo consortium that signed an EPC contract with Greenlink Interconnector Limited in September 2021 for the 500 MW Greenlink HVDC interconnector between Ireland and Great Britain. Sumitomo is responsible for the design, engineering, manufacture, supply, installation, and commissioning of the 320 kV HVDC XLPE cable system, covering both the subsea and underground sections, plus associated fibre-optic cables. The system comprises approximately 160 km of subsea route and 30 km of onshore route (24 km in Ireland and 6 km in Wales), implemented as a symmetric monopole with two parallel cables, implying about 320 km of subsea and 60 km of onshore cable manufactured and installed. Work started in early 2022, with Sumitomo completing all onshore and offshore HVDC cable installation, testing, and commissioning ahead of schedule and handing over the cable system to consortium partner Siemens Energy in 2024 for trial operations and full integration with the converter stations.
