The company Nexans has completed the first cable laying operation of the Celtic Interconnector project in French territory after finishing preliminary work in Ireland. This maneuver was carried out with the support of the vessel Calypso, ensuring the continuity of a project that will electrically connect continental Europe with the Irish grid.
The Celtic Interconnector Infrastructure
Indeed, the technical data for this link are impressive in their scale and precision. The corridor extends 575 kilometers between Brittany and East Cork, utilizing 320 kV high-voltage direct current technology.
Consequently, the transmission capacity stands at 700 MW, a figure capable of covering the demand of 450,000 households. Likewise, the submarine cable engineering utilizes extruded XLPE insulation manufactured in Norway, while the land sections originate from specialized plants in Belgium and Switzerland.
This advancement improves the stability of the European Union’s integrated electricity system. The collaboration between operators RTE and EirGrid makes this project a tangible reality for the exchange of clean energy and the strengthening of cross-border solidarity.
The technical operation in France represents a step towards a more resilient grid where the integration of renewable sources is the norm. This is a strategic infrastructure that guarantees greater autonomy for both countries and efficient management of international electricity flows.
