GREENLINK INTERCONNECTOR LIMITED says it welcomes the decision by Natural Resources Wales (NRW) to approve its application for a Marine Licence for the Greenlink electricity interconnector project, which will link the power markets of Great Britain and Ireland.
An important project for Pembrokeshire, and the UK as a whole, NRW’s go-ahead is one of several consents required for the construction of the project and covers installation of the marine cable in UK waters.
The approval is a major milestone for Greenlink and joins the onshore planning consents granted unanimously in July last year by Pembrokeshire County Council and Pembrokeshire Coast National Park Authority.
Greenlink’s proposed 190km subsea and underground electricity cable will run beneath the Irish Sea to connect National Grid’s Pembroke Power Station in Wales and EirGrid’s Great Island substation in County Wexford, Ireland. It will have a nominal capacity of 500 MW.
Nigel Beresford, CEO for Greenlink Interconnector Limited, said: “We are delighted by Natural Resources Wales’s decision to grant this licence. This marks a significant milestone for Greenlink and another important step towards project construction, which we expect to commence later this year.
“The Greenlink team has worked constructively with Natural Resources Wales and Welsh marine stakeholders to find workable solutions to the many technical and environmental challenges facing a large infrastructure project like this, and this has been reflected in the quality of the final proposal.
“The thorough environmental and technical assessments we have undertaken, supported by the practical and value-adding feedback we have received from key marine stakeholders, have ensured that we move forward confident that we are delivering a well-designed project with the interests of the Welsh marine habitat at its core.”
The subsea section of the cable will be approximately 160km in length and uses high voltage direct current (HVDC) technology. The preferred route and installation methods were chosen following the conclusion of subsea surveys and consultation with key stakeholders.
In Ireland, a Foreshore Licence application was submitted to the Department of Housing, Planning and Local Government (Foreshore Unit) in 2019 and the onshore planning application was submitted to An Bord Pleanála in December 2020.
Greenlink is one of Europe’s most important energy infrastructure projects and brings benefits on both sides of the Irish Sea for energy security, regional investment, jobs and the cost-effective integration of low carbon energy. The project will offer important local supply chain opportunities and plans are being drawn up for ‘meet-the-buyer’ events in the local area prior to construction.
Once fully consented, Greenlink is expected to have a three-year construction programme, with commissioning planned by the end of 2023.
