Celtic Interconnector (Ireland–France)

Under construction

Irish onshore cable installation and testing were reported complete in May 2026. Celtic connects Ireland directly to France. It is included as a neighbouring-market project relevant to all-island electricity trading; it is not a Great Britain grid connection.

What this link contributes

This asset provides a route for electricity to move between networks or strengthens the network carrying that electricity. Its capacity cannot be added to wind, solar or power-station capacity as though it were another generator.

Ireland ↔ France

Converter stations, cable manufacture, offshore installation, landfall works and grid energisation can progress at different times. The status above describes the documented project stage rather than assuming all work packages are complete.

Project location

Connection sites and areas are shown separately. Dashed circles mark approximate endpoint areas. No straight line is presented as the cable or overhead-line route.

Markers identify sites, published points or labelled connection areas. Markers are not site boundaries or entrances. EGL2’s additional outlines and route layers are explicitly identified in the developer’s map data.
