Following technical assessments and feedback from local stake holders, EirGrid has decided to bypass the two East Cork villages, Castlemartyr and Killeagh, for the onshore cable route of the proposed Celtic interconnector.

Initially, the cable was planned to pass through the two villages, but now EirGrid is planning to lay the cable in agricultural land north of Castlemartyr and south-east of Killeagh.


EirGrid's chief infrastructure officer, Michael Mahon, said,

"routing the cable circuit through Killeagh and Castlemartyr presents challenges. Instead, we are proposing to lay the cable in agricultural land north of Castlemartyr and south-east of Killeagh. We are in discussions with landowners close to both villages and are confident that we can come up with a very satisfactory solution".


EirGrid will commence written communication with landowners to update them about the new proposed route. Studies and assessments of the new proposed route are underway, and the project's planning application will be submitted by April. The decision to planning application can be expected in ~12 months, which will lead to start of the construction phase in 2022.


The 320 kV
Celtic Interconnector will be the first direct link between Ireland’s electricity network and mainland Europe. The 600 km link will be partly developed by French and Irish TSOs, RTE and EirGrid. The €1 billion project received €530.7 million of support from the European Commission in 2019.
