To achieve its climate and energy goals, Europe needs to further develop cross-border electricity interconnections. The Celtic Interconnector project will help to meet these targets for interconnection which are key to the achievement of Europe’s energy transition. Through facilitating more renewable energy to come onto the network, interconnection will also help to reduce greenhouse gas emissions associated with power generation in Europe.
Through a decision issued on the 14th of October 2013, the European Union recognised the France-Ireland interconnector as a Project of Common Interest (PCI). This was reconfirmed on the 23rd of November 2017. The EU also labelled the Celtic Interconnector as an e-Highway project in November 2015.
In addition, the project will also help to achieve plans to develop the French, Irish and European network (TYNDP-Ten Year Network Development Plan).

Interconnection is seen as key to a more integrated European electricity system with the aim of completing the European energy market. In turn this is seen as important in order to help the EU achieve its energy policy and climate objectives of affordable, secure and sustainable energy for all citizens, as well as the long-term decarbonisation of the economy.

High Voltage Direct Current (HVDC) is the only viable option given the distances needing to be covered.
