  • Interconnectors - France

  • Interconnexion France-Angleterre - operational

    Interconnexion France-Angleterre (IFA) is a 2,000MW high voltage direct current (HVDC) electrical interconnector between the British and French transmission systems and was commissioned in 1986. It is approximately 70km in length, with 45km of subsea cable.

    The GB landing point for the sub-sea cables is near Folkestone, Kent, from where underground cables connect to Sellindge converter station and then on to the GB transmission system. The French landing point for the sub-sea cables is near Calais, from where underground cables connect to Les Mandarins converter station and then on to the French transmission system.

    National Grid Interconnectors Limited is a wholly owned subsidiary of National Grid Plc and jointly owns and operates the interconnector with Réseau de Transport d'Electricité (RTE), the French Transmission System Operator. 

    Capacity is offered for sale to Eligible Users, separately in the direction Great Britain to France and France to Great Britain, through auctions for different contractual periods.

    Interconnexion France-Angleterre (IFA2) - in development

    What is IFA2?

    IFA2 is a proposed high voltage direct current (HVDC) electrical interconnector linking the British and French transmission systems that will be capable of exporting or importing 1000MW of power between the two countries.  It will be the second link to France following the commissioning of IFA in 1986.

    Who are IFA2?

    The project is being jointly developed by National Grid and Reseau de Transport d’Electricite (RTE), the French network owner and operator. RTE will have responsibility for the French elements of the project.

    National Grid IFA2 Ltd is the company that National Grid has formed to develop and bring forward the IFA2 project.

    In November 2014 the Gas and Electricity Markets Authority (GEMA) granted an Electricity Interconnector licence to National Grid IFA2 Ltd, which is a requirement in order for it to own and operate electricity interconnector assets in Britain.

    In July 2015, the Office of Gas and Electricity Markets (OFGEM) granted IFA2 a cap and floor regulatory regime in principle for National Grid’s share of the IFA2 project. More information can be found here.

    Project overview

    The project proposals consist of the following components:

    British and French waters

    • Two high voltage direct current (HVDC) submarine cables running 204km between Great Britain and France, which will be buried in the seabed

    UK  

    • HVDC cables routed to the east of the Isle of Wight and coming ashore at the eastern shore of the Solent ,at a point known as Monks Hill Beach, at the southern end of Daedalus Airfield
    • Onshore HVDC cables will be buried underground and run from the landing point at Daedalus to a converter station to the north east of Daedalus Airfield
    • A converter station is proposed to the north east of Daedalus Airfield to change electricity between direct current (DC) and alternating current (AC) and vice versa
    • High voltage alternating current (HVAC) underground cables to be routed from the converter station back to the cable land fall at Monks Hill Beach
    • HVAC subsea cables buried in the seabed and routed offshore for approximately 4km to a cable landfall at Brownwich, near Warsash
    • HVAC land cables buried underground and routed for approximately 2km to the point of connection to the grid at Chilling 400kV substation, near Warsash, Hampshire
    • There will be new equipment within the existing substation at Chilling

    France

    • Subsea HVDC cables to come onshore to the east of Merville-Franceville-Plage
    • HVDC land cables will be buried and run underground for approximately 24km to the converter station
    • A converter station is proposed to be located near La Hogue, east of Caen that will change electricity between direct current (DC) and alternating current (AC), and vice versa
    • High voltage alternating current (HVAC) underground cable will be routed from the converter station to the adjacent Tourbe 400kV substation

    The project will make a positive contribution to European energy policy objectives - helping Great Britain reach its goal of meeting a minimum 10% interconnection target by 2020.

    For more information on the Government’s position on interconnection, please download the Government Department for Energy and Climate Change publication More interconnection: improving energy security and lowering bills

    The European Commission published its first list of Projects of Common Interest (PCI) in 2015 and IFA2 was identified as one of 195 key energy infrastructure projects selected to be a PCI. PCIs are essential for completing the European internal energy market and for reaching the EU's energy policy objectives of affordable, secure and sustainable energy.

    To become a PCI, a project must have a significant impact on the energy markets and market integration of at least two EU countries. It must also boost competition on energy markets and boost the EU's energy security by diversifying sources, as well as contribute to the EU's climate and energy goals by integrating renewables.

    For more information on PCIs please visit the European Commission’s website.

    PCIs are governed under Regulation (EU) No 347/2013 on guidelines for trans-European energy infrastructure, referred to as the TEN-E Regulations.

    Public consultation in Great Britain

    In December 2015 a series of public consultation events were held in the Boroughs of Fareham and Gosport, between the communities of Lee-on-the Solent, Stubbington and Warsash and Peel Common.  A second public consultation was held in March 2016. A copy of the consultation feedback report, covering both rounds of consultation can be viewed here.  

    Applications for planning permission and a marine licence

    Following the second round of public consultation on the proposals in March 2016, applications for planning permission to Fareham Borough Council (FBC) and a Marine Licence to the Marine Management Organisation (MMO) were submitted on 9th May 2016. A decision on both applications is expected later this year. 

    Onshore proposals

    The outline planning application is accompanied by the Environmental Statement (EIA) and a number of supporting documents and can be viewed on Fareham Borough Council's website, planning ref: P/16/0557/OA by clicking here

    Offshore proposals
