EirGrid Launches Latest Consultation for the Celtic Interconnector.


11 November 2019

Cork, November 11th – EirGrid is launching a 12 week consultation to help determine exactly where the Celtic Interconnector should be built.

The state-owned company that develops and operates the national electricity grid is seeking feedback on the location of the converter station, a landfall location and the underground cable routes which make up the flagship project.

The Celtic Interconnector will provide the first direct energy link between Ireland and France via a 500km submarine electricity cable between East Cork and the north-west coast of Brittany. There will be a further approximately 40km of cables on land in Ireland and France. The interconnector will have a capacity of 700 megawatts (MW), enough to power 450,000 households.

This is the latest round of consultation on the project. Between April and June the public was consulted on a shortlist of three proposed landfall locations on the coast of East Cork as well as six possible zones for a converter station, an industrial-type building with electrical equipment that converts direct current electricity to alternating current and vice versa.

Following that consultation and further analysis, Claycastle Beach is emerging as the best-performing landfall option while attention is being focussed on three locations for the converter station. These are at Kilquane, which is emerging as the best-performing option, Knockraha and Ballyadam. The public will be asked for any missing or new information relating to these options and the associated underground cable routes.

All stakeholders and communities are invited to submit their feedback between Monday, 11th November and Sunday, 2nd February 2020. This can be done
online, by attending public information days (see below), or by email, phone or in writing. Read our Step 4 brochure for more information on the shortlisted options.

The project has progressed to Step 4 of EirGrid’s six-step public consultation framework for infrastructure projects. Feedback during this consultation, alongside the results of ongoing studies, will help identify the final best-performing option in early 2020. The project will then progress to Step 5 and detailed environmental assessments will be carried out before the start of the formal planning process, which is expected in the second half of 2020. 

The Celtic Interconnector is being jointly developed by EirGrid and Réseau de Transport d’Électricité, the electricity transmission system operator in France. It is expected to be completed in 2026.

The interconnector will help Ireland achieve its climate change goals, put downward pressure on the cost of electricity, enhance security of supply and provide a direct fibre optic telecommunications link with Continental Europe.
