Siemens and Sumitomo awarded Ireland-UK interconnector

28 September 2021


Greenlink has awarded the EPC contract for the Greenlink electricity interconnector project to a consortium comprised of Siemens Energy AG and Sumitomo Electric Industries Ltd. 

As part of an overall project investment that exceeds €500m, the contract will deliver the 500 MW, 190 km subsea and underground electricity interconnector to connect the power grids of Ireland and the United Kingdom.  

The engineering, procurement, and construction contract will cover works on the onshore and subsea high-voltage direct current (HVDC) cable systems, two converter stations, a tail station at Great Island in Wexford and onshore cable works in Wexford and Pembrokeshire, Wales.  The award also includes a service and maintenance contract for operations and maintenance following commissioning of the project, which is expected to be in 2024. Work will begin at the start of 2022, following financial close.  

The project is considered of critical importance in Europe and has been awarded ‘Project of Common Interest’ status by the European Commission. It is owned on behalf of its clients by leading global private markets firm, Partners Group, which has more than US$119 billion in assets under management. 

Greenlink will offer local supply chain opportunities and plans are being drawn up for ‘meet-the-buyer’ events for potential suppliers in the local areas prior to construction.
