A 1GW electrical interconnector between the United Kingdom and France via the Channel Tunnel

  • A new infrastructure adding value to the Group: 25-year exemption for the sale of capacity
  • 1,000MW electricity capacity, equivalent to the consumption of 2 million households
  • A 2-year construction work: creation of 300 jobs on site, of which 40 permanent for ElecLink
  • A minimal impact on the environment.

1,000MW direct current interconnector through the Channel Tunnel

logo ElecLink

The ElecLink project aims to build, install and operate an electricity interconnector between the United Kingdom and France, by installing two direct current cables inside the Channel Tunnel. These two cables will enable the electricity produced, on either side of the Channel, to circulate between the two countries as needed. The new interconnector ElecLink, a subsidiary wholly- owned by Getlink, will increase the current transmission capacity between the United Kingdom and France by 50%. Major project to add value to the Tunnel infrastructure, ElecLink is able to generate stable and secure long-term revenue for the Group.

Labelled as «European project of common interest”, the project has already obtained support from both countries when launched in 2012, and also all the authorisations from the relevant regulatory authorities.

Construction works

Building the interconnector requires the installation of direct current cables in the North rail tunnel, the construction of two converter stations located at Folkestone (UK) and Peuplingues (FR) and the burying of alternating current cables between the converter stations and the national networks of British operator NGET and French operator RTE.

Launched in February 2017, the construction works are expected to last 36 months, with entry into operational service scheduled for the beginning of 2020.

Proven technologies and world-class partners

Following a tender process, the Engineering Procurement and Construction (EPC) contracts were awarded to partners with an international reputation: Siemens is building the converter stations, Balfour Beatty/Prysmian are responsible for the manufacturing and installation of the DC cables in the Tunnel and the underground AC cable system in the UK.

Safety, a top priority

ElecLink uses reliable technology for its high-voltage direct current system, for its cables and converter stations. A comprehensive safety study was conducted for the conception, construction, operation and maintenance phases of the project.

Security, both in terms of construction and operation of the cable in the Tunnel, is a top priority for the Group and is monitored regularly by the Channel Tunnel Safety Authority (CTSA). Technologies used meet the highest health, safety and environmental protection requirements, under the auspices of the IGC (intergovernmental Commission).

A minimal impact on the environment

The ElecLink project is distinguished by an exceptionally low impact on the environment. Using the existing infrastructure of the Fixed Link, ElecLink will avoid any interference with the marine ecosystem. Supporting the balance of the energy mix of the UK and France, ElecLink will also lead to a reduction in carbon emissions of 6.1 million tonnes.
