Cross Shannon Cable Project

400 kV submarine cable in the Shannon Estuary

This page shows you information on this project's activity, with more recent news first.

March 2022

A public consultation on the Foreshore Licence Appropriate Assessment (ecology of designated Natura sites) for the EirGrid Cross Shannon Cable Project was launched on the 31st March  by the Department of Housing, Local Government and Heritage Foreshore Unit. Consultation is now underway and will complete on the 29th April.

During this time the application will be available for viewing online here and in hard copy at Kerry County Council, Planning Department, Listowel Garda Station, Clare County Council, Planning Department and Kilrush Garda Station, Co. Clare.

Please note observations or submissions will need to be sent directly within 30 days from 31st March to the Minister for Housing, Local Government and Heritage at Foreshore Unit, Department for Housing, Local Government and Heritage, Newtown Road, Wexford, Co. Wexford or by e-mail to (Quoting Ref: FS007083).

June 2021

EirGrid are pleased to announce that we received confirmation from An Bord Pleanála on 4th June that the Cross Shannon 400 kV Project received planning approval following the submittal of the Strategic Infrastructure Development application last August, and a Request for Further Information in December.

This is a significant milestone that has been achieved in the project’s programme. We now look forward to closing off the foreshore licence process with the Dept. of Housing and completing the scoping process with ESB Engineering & Major Projects, which will facilitate the delivery of this major system reinforcement for the south west region and the wider electricity transmission system.

EirGrid would like to sincerely thank all stakeholders that engaged in the planning application process over 2019 & 2020. Your input and feedback has allowed for the project to reach this milestone and we will continue to brief stakeholders as necessary as the project progresses into the construction phase.

July 2020

Following extensive stakeholder, community and landowner consultation and engagement during the second half of 2019, as well as further technical and environmental studies, EirGrid have confirmed the nature and location of the planned development and are in the closing stages of completing the planning documentation.

In summary the project will comprise of subsea cables within the seabed of the Shannon estuary, and underground cables on land on both the northern and southern shores of the estuary near the existing substations at Moneypoint and Kilpaddoge.

A planning application, and a separate foreshore licence application, was submitted this month. The planning application was made directly to An Bord Pleanála as Strategic Infrastructure Development (SID); this required the creation of a specific planning application website – please find the link to the planning application website here. The foreshore licence application will be made to the Department of Housing, Planning and Local Government.

June 2019

EirGrid is seeking feedback from landowners, local organisations and community on the best-performing option for the Cross Shannon Cable Project. We held two public consultation open days, one in Tarbert  on 17th June and another in Kilimer on 18th June.

See map of feasible cable route options here.

The consultation remains open until 29th July. Please contact our community liaison officer Eoghan O’ Sullivan on 087 247 7732 or

Progress to date

Earlier this year EirGrid completed marine surveys in the Shannon Estuary close to Moneypoint electricity generating station in Clare and Kilpaddoge substation in Kerry.

These geophysical and geotechnical surveys provided detailed information on the submarine conditions and terrain. This enabled us to identify feasible routes for the proposed 400 kV cable connecting Moneypoint and Kilpaddoge, including what we believe is the best-performing option.

Once the current round of consultation has been completed, the route of the Cross-Shannon Cable will be finalised to allow the project to progress to the planning phase of the project.

EirGrid will prepare a foreshore licence application and a planning application during the autumn of 2019. The planning application is likely to be made directly to An Bord Pleanála and the foreshore licence application will be made to the Department of Housing, Planning and Local Government.  Applications will be advertised in local media and the documentation will be available for public inspection and submissions.

November 2018

Following the first phase of marine surveys carried out by EirGrid in July 2018, the second and final phase of the marine surveys are now underway. Over the coming weeks EirGrid is undertaking a geotechnical marine survey of the Shannon Estuary between County Clare and County Kerry in the environs of Moneypoint electricity generating station (Co Clare) and Kilpaddoge substation (Co Kerry). This final phase will further assist the assessment of the feasibility of a 400 kV submarine electricity cable connecting the Moneypoint and Kilpaddoge electricity substations.

You may notice survey vessels off-shore starting from Monday, 30 November for a period of 15 to 20 days, dependent on weather conditions. You may also notice survey personnel on the foreshore and beaches in the survey area during this period. No significant disruption to users of the foreshore is expected.
