Public consultation kicks off for Greenlink Interconnector

Details have been announced of the first round of public consultations for the proposed Greenlink interconnector, which will stretch approximately 170km under the Irish Sea to connect the electricity transmission networks in Wales and Ireland.

Greenlink is one of Europe’s most important energy infrastructure projects and brings significant benefits on both sides of the Irish Sea for energy security, jobs and the cost-effective integration of low carbon energy. The €400 million privately-financed project is being developed by Greenlink Interconnector Limited and planned for commissioning in 2023.

The first set of exhibitions will take place in Pembroke Dock, Hundleton and Angle in Pembrokeshire, Wales, on 29th, 30th and 31st May (see below for details).

In Pembrokeshire the interconnector will consist of a subsea cable that is intended to come ashore under the beach and dunes at Freshwater West and then continues underground to a converter station located near to the existing Pembroke substation. Several underground cable routes are being assessed along with three potential converter station sites.

Speaking about the upcoming public consultation events Simon Ludlam, Project Director, said;

“During the public consultations we will be sharing the details of the project and the surveys we propose to complete to ensure that the final proposal is of the highest standard. We will be asking for feedback on the proposed surveys, potential converter station sites and cable routes along with listening to any additional issues residents and local stakeholders feel we should be considering.

“A large infrastructure project also provides opportunities to local businesses. We will be keen to hear from all local businesses that would like to be involved in the project – from civil engineering firms to local bed and breakfasts.”

Details of the public exhibitions are provided below:

Pembroke Dock: 29th May 2018 – 14:00 to 20:00 - Pater Hall, Dimond Street, Pembroke Dock SA72 6DD

Hundleton: 30th May 2018 – 14:00 to 20:00 - Hundleton Sports Pavillion, Hundleton, Pembroke

Angle: 31st May 2018 – 14:00 to 20:00 - Angle Village Hall, Angle, Pembroke SA71 5AS

The details of public exhibitions to be held in Ireland will be announced shortly.

Simon Ludlam continued;

“Greenlink is a nationally important infrastructure project but we want to deliver it as a local project – maximising local content and ensuring that the views of local people are fully considered throughout the development process.

I encourage residents and other local stakeholders to attend the public exhibitions, come and meet the team and have their say in how the project progresses.”

Notes to Editors:

Greenlink is a proposed 500MW, subsea and underground cable interconnector (with associated converter stations) between the existing electricity grids in Ireland and the UK, operated respectively by EirGrid and National Grid Electricity Transmission. The project will link the Great Island transmission substation in County Wexford (Ireland) and Pembroke transmission substation in Pembrokeshire (Wales).

Greenlink has key strategic importance, as it will provide significant additional interconnection between Ireland, the UK and continental Europe, contributing to each country’s interconnection objectives, enhancing energy security and enabling the further integration of renewable, low carbon energy sources.

Constructing and commissioning an interconnector requires the completion of a thorough programme of environmental and technical assessment to ensure that the final interconnector design fully considers the environment in which it is built. A planning application is scheduled to be submitted to Pembrokeshire County Council in March 2019, with construction due to commence in 2020. The project is due to be commissioned in 2023.
