The second electrical interconnection between the Isle of Jersey and France (one of RTE's 45 international links), is among the very first projects conducted by RTE Normandy.

Thanks to the interconnection with France, electrical supply to the Anglo-Norman islands is secure.
This interconnection is materialized by a 90,000 volt undersea cable, placed on the sea bottom, linking the Isle of Jersey to the Cotentin peninsula in France (Manche department). On the French territory, the undersea cable was prolonged by high voltage 90,000 volt underground cable that ends at the electrical transformer station in Saint-Rémy-des-Landes.
This second link brings electrical power capacity up to 135 Megawatts (the first link, with power of 50 Megawatts, has been running for 15 years), enabling the Isle of Jersey to satisfy variations in demand during the year, as well as consumption peaks, in total security. Designed for alternative current, the link optimizes the quality of electrical supply and enables frequency stabilization at the European standards of 50 Herz.
In addition, thanks to the existing electrical link between Jersey and Guernsey, this new 135 MW capacity enables electrical supply to the second Anglo-Norman island.

An underground cable, factor of progress for the environment
The environmental benefits are also real. As concerns the island of Jersey, the interconnection has made it possible to significantly reduce usage of fuel-powered thermal power stations (the Collette station is closed, only the Queen's Road station is still in operation) and therefore to reduce greenhouse-effect gaseous emissions.
A study on the impact of the installation of the undersea cable has been conducted by IFREMER.
On the French side, installation of the underground cable on the Saint-Rémy-des-Landes beach was carried out in close collaboration with the Conservatoire de l'Espace Littoral et des Rivages Lacustres (French Conservatory for Coastal Areas and Lacustine Banks) which identified the remarkable species of flora and fauna to be protected and preserved, as well as the dunes environment. Upon completion of this partnership, a portion of the abandoned site of the former Surville electrical power station was sold, by attorney-drafted deed, in July 2001, to the Coastal Conservatory.
The new electrical power station in Saint-Rémy-des-Landes has been landscaped. The architectural and landscaping plans were validated by the Departmental Commission for Sites.

A project conducted with exemplary consultation with the officials from both countries
This link illustrates the privileged relations between Normandy and the Anglo-Norman islands, and has even strengthened them. In France, the ambition of the project's players to work in synergy was achieved through a Regional Consultation Committee presided by the President of the Regional Council of Lower Normandy.
This achievement, in which, as manager of the electrical grid system, RTE acted as project manager for connecting the new cable to the French system, represents an investment of 579 MF (88,26 millions euros) - 490 MF for the Jersey Electricity Company (74,70 millions euros) and 89 MF for RTE (13,56 millions euros).
