The Celtic Interconnector is the name of an EU Project of Common Interest (PCI) aiming the development of a potential electrical connection between Ireland and France, using subsea cables, with the capacity of approximately 700 megawatts (MW), enough to power 450,000 households. The project is being jointly developed by Ireland’s state-owned transmission system operator (EirGrid) and its French counterpart Réseau de Transport d’Électricité (RTE). The interconnector is expected to go live in 2025.


Parts of this project - the feasibility study, the initial design and the pre-consultation - are co-financed by the Connecting Europe Facility (CEF). The feasibility study (€3.8 million of EU funding) was completed in 2016 and included marine surveys, preliminary design studies as well as commercial, legal and governance aspects. The main conclusion of the feasibility study is that the project is feasible and that the business case is sufficiently compelling to progress into the next development phase. The next phase of the project (initial design and pre-consultation) will receive €4 million of EU funding and comprises an in-depth economic assessment of the project, initial technical design specifications, environmental studies and pre-consultation in preparation for permit granting procedures in France and Ireland. This latest phase is expected to be completed in 2018 and pave the way to the construction of the interconnector.


The Connecting Europe Facility in the field of energy provides funding to infrastructure projects in electricity, natural gas and smart grids with the aim to better interconnect energy networks towards a single energy market in Europe. The programme supports the key objectives of the Energy Union by promoting further integration of the internal energy market, enhancing security of energy supply and integrating energy from renewable sources into the network.
