The Project


The Greenlink project requires planning permission in Ireland and Wales. A electricity grid connection agreement for 500MW is already in place between Greenlink and the UK’s National Grid for a connection at Pembroke Substation in Wales.

In Wales, Greenlink will consist of a converter station sited close to the existing Pembroke substation and underground cabling that will predominantly be routed across agricultural land.

Various detailed technical and environmental surveys have been carried out during the development process to ensure that the final design fully incorporates the challenges and opportunities of the local environment.

Technical and environmental studies have included:

  • bird studies;

  • ecological assessments;

  • construction and access studies;

  • landscape and visual impact assessments;

  • noise assessments;

  • traffic and transport assessments;

  • cultural heritage assessments;

  • geological assessments;

  • and site hydrology assessments.











In July 2020 the onshore planning applications in Wales were approved unanimously by Pembrokeshire Coast National Park Authority and Pembrokeshire County Council. Read the press releases here.

The developers of the Greenlink project strongly believe that a proactive and constructive dialogue with stakeholders, throughout the development programme, has resulted in a high quality and comprehensive application being submitted and delivered.


Construction of Greenlink is expected to lead to significant expenditure in Wales.  We are committed to maximising the use of locally-based contractors and personnel during the construction and operational phases of the project and are keen to hear of local businesses that could benefit. Let us know if you would like to be added to our list of local suppliers.

Full details of the onshore converter station and the onshore and offshore cable routes, along with the technical and environmental assessments, can be found in the public consultation Information Brochure. You can view all planning documents on our Planning page.
