The Celtic Interconnector

The Celtic Interconnector is a planned subsea (undersea) link to allow the exchange of electricity between Ireland and France. Since 2011, EirGrid has been working with its French equivalent Réseau de Transport d’Electricité (RTE) to find the best way to develop the interconnector to benefit electricity customers and markets in Ireland, France and the EU. We are working together to deliver the Celtic Interconnector, which, if built, is due to be completed in 2026. As Ireland’s state-owned transmission system operator (TSO), part of EirGrid’s role is to explore and develop opportunities to interconnect the transmission grid with the transmission grids in other countries.
