a European Project of Common Interest
To promote the movement of electricity flows at a European level
By promoting the movement of electricity in Ireland, in France and throughout all of continental Europe, the Celtic Interconnector will enable European consumers to benefit from a more open electricity market.
To strengthen the security of supply between countries
The Celtic Interconnector project will strengthen the security of electricity supply between the two countries enabling them to rely on one another in case of unexpected events (technical incidents, spikes in consumption…).
To support the development of a more sustainable electricity mix in France and in Ireland
The Celtic Interconnector will contribute to the European objectives of a low-carbon energy future, promoting the development of other renewable energy sources and their integration into the European electricity system.
A project working towards a carbon-free Europe (by 2030)
- Each country must have an electrical interconnection capacity of at least 15% of its installed production
- 40 % reduction in greenhouse gas emissions compared to 1990 levels
- A renewable energy target of at least 27% of final energy consumption by 2030
- Achieve targets for an improvement in energy efficiency at EU level of at least 27% (rising to 30%)

Recognised as a Project of Common Interest (PCI) by the European Union in October 2013, and with designation renewed in 2017, the Celtic Interconnector project falls within the scope of the development of electrical interconnectors which is one of the levers for supporting energy transition in France, in Ireland and in Europe.
in the network of tomorrow
France and Ireland are both examining the project in accordance with their national procedures. Moreover, as the Celtic Interconnector has been identified as a Project of Common Interest (PCI), both countries will ensure provision of information to and participation of the public, in accordance with European requirements.
