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.

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.
