ElecLink is a 1000 MW HVDC electrical interconnector between the UK and France, passing through the Channel Tunnel.
ElecLink commenced operations on 25 May 2022 following several delays due to safety concerns.
Route
The 51 km (32 miles) DC cable runs via the Channel Tunnel between converter stations at Peuplingues in France and Folkestone in the UK, with an additional 14.5 km (9.0 miles) of underground AC cable on the English side, and 3.5 km (2.2 miles) on the French side, to link the converter stations to the existing transmission networks.[4]
Ownership
It is owned by a subsidiary of Getlink, which owns the tunnel itself.
ElecLink is the first UK interconnector to be entirely funded by private finance, without being underwritten by electricity consumers.[5]
Construction
The station was designed and installed primarily by Siemens AG and Siemens FIT (Field installation Team) with the help of Balfour Beatty, Galaghers, Mclaughlin & Harvey and many more. The contract for manufacturing the HVDC cables awarded to Prysmian.[1]
A specialist, 500 m long, battery-powered works train was manufactured for the project to allow the HVDC cable to be installed[6][5] in 2021 and tested.[7]
Project history
Work commenced on the project in 2017,[3]
The foundation stone of the Folkestone converter station was laid in February 2017, by Jesse Norman MP, Minister for Industry and Energy.[8]
In 2019, the Anglo-French Channel Tunnel Intergovernmental Commission (IGC), which oversees the safety of the Channel Tunnel, suspended part of the project's consent due to concerns about safety of the HVDC cables within the tunnels.[9] This decision prevented the cables from being installed. The IGC was expected to make a final decision on whether the cables can be installed in April 2020, based on a recommendation from the Channel Tunnel Safety Authority,[10] however this approval was again delayed due to further safety concerns and the COVID-19 pandemic.[2]
In December 2020, the IGC announced its approval of the project, with the cable expected to be installed by summer 2021 and commercial operation expected to start in mid-2022.[2]
In February 2022, the IGC and national safety authorities announced their approval of ElecLink, which allowed final testing of the interconnector to commence, with entry into service still planned for mid-2022.[11]
ElecLink commenced operations on 25 May 2022.
