EIRGRID is launching a 12-week consultation to help determine exactly where in Cork the Celtic Interconnector should be built.
The company 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.
The interconnector will have a capacity of 700 megawatts (MW), enough to power 450,000 households.
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.
All stakeholders and communities are invited to submit feedback between Monday, November 11 and Sunday, February 2, 2020. This can be done online, by attending public information days, or by email, phone or in writing.
