Consultation in the UK
A subsea electricity cable off the coast of the United Kingdom: your questions answered
RTE and EirGrid recently held an information and public consultation process in the United Kingdom (UK) on the Celtic Interconnector project as part of the Project of Common Interest (PCI) process. During the consultation, stakeholders were invited to submit questions on the project through this online forum which was open form the 16 June up to and including the 13 July 2020. This online consultation forum is now closed however it will remain available on a read only basis until Tuesday 13 October 2020. A report on consultation activity in the UK will be made available in September 2020. For additional information on the project and the subsea electricity cable route through the UK Exclusive Economic Zone please refer to our dedicated UK stakeholder brochure.

Your questions - Our answers
How visible is the interconnect coming onto the beach at youghal? Is it hidden on the beach?
By Anonymous (July 8 2020)
Dear Mr Nolan,
Thank you for your question. The focus of this consultation is for aspects related to the UK portion of the project but we would be happy to answer your question related to the Irish portion of the project.
The landfall point is where the land circuit (underground cable) will connect to the submarine circuit by way of an underground transition joint. This will be installed behind the beach where the submarine circuit comes ashore. The landfall point will be fully re-instated and the interconnector will not be visible on the beach following completion of the works.
Please refer to the below infographic which outlines what the Celtic Interconnector project will consist of in Ireland.

I am a global cable specialist supplier and was wondering if you could provide me information with regards the purchase of cable or tender for this project, your feedback is greatly appreciated. John

Many thanks for your query. The public consultation is intended to increase public participation in the permit granting process and ensure an informed dialogue with the public regarding the project development. Given that your query is outside of the scope of the public consultation process it would be appreciated if you could direct your query directly to the team at email@example.com and/or firstname.lastname@example.org

How deep will the cables be buried and how will the excavation affect marine and aquatic life in the vicinity?
By Mr. Patrick O’MAHONY, Horsham, United Kingdom (June 19 2020)
Many thanks for your question.
The depth of burial will vary depending on the geology of the seabed and any risk from fishing and shipping activity in the area of the submarine cable, where trawling and the dropping of anchors for example, can pose a risk.
Bearing this in mind, within United Kingdom (UK) Exclusive Economic Zone (EEZ) waters, the anticipated depths of burial will vary between approximately 0.5m and 2.5m.
It is anticipated that there may be some sections of the route where burial of the cable may be challenging due to the presence of more challenging seabed strata. In such areas where conventional burial tools fail to achieve the target burial depths, the cable may be laid on the seabed and protected by rock placement or secondary protection to ensure adequate protection of the submarine cable.
Rock placement will also be used to protect the submarine cable where it may need to cross over other existing subsea cables and pipelines.
The marine route was identified to ensure that no Environmentally Designated Areas or sites were crossed, in Ireland, France or in the UK EEZ however there will invariably be marine and aquatic life in the vicinity. EirGrid and RTE are committed to protecting and respecting the marine environment affected by the interconnector in all countries and will consult with all relevant authorities and stakeholders.
All relevant legislation will be complied with including the requirements of the UK’s Marine and Coastal Access Act 2009 and the Habitats and Species Regulations 2017.
