Cross Shannon Cable Project

400 kV submarine cable in the Shannon Estuary


The Cross Shannon Cable Project is a submarine cable that will link the electricity substation at Kilpaddoge in North Kerry to the Moneypoint generating station in Clare.

Planning approval was received from An Bord Pleanála in June 2021. We plan to construct the Cross Shannon Cable project in 2022 and 2023.

Why is this project needed?

There are large amounts of renewable electricity generation being connected to the electricity grid in the south and west of Ireland. During times of high wind, the Cross Shannon Cable Project will facilitate the flow of this power to the east of the country.

Are electricity cables crossing the Shannon a new technology?

No, electricity transmission cables have been laid previously in the Shannon Estuary including the Prospect Tarbert 220 kV cables which were laid in 1977, and the Moneypoint Kilpaddoge 220 kV cables which were installed in 2015.
