IFA2 is a 1,000 MW high voltage direct current (HVDC) electrical interconnector currently under construction between the British and French transmission systems. It will be the second link to France that National Grid has developed with RTE.

Why do we need interconnectors?

An interconnector allows countries to exchange power, helping to ensure safe, secure and affordable energy supplies. They are the heart of the transition to a smarter energy system and integral to delivering a more flexible energy system for consumers.

Why do we need IFA2?

IFA2 will provide the capability to export or import 1,000MW of power. This brings three important benefits for our national energy requirements:

Affordability:

By giving Great Britain access to the European electricity market, IFA2 should help create downward pressure on wholesale electricity prices. We estimate that each 1,000MW of new interconnector capacity has the potential to reduce wholesale prices in Great Britain by up to 2%.

Security of supply:

Consumers throughout Europe use electricity in various ways at different times of the day, and interconnection allows electricity to be moved to where it is needed. This is particularly important at times of ‘system stress’, such as a combination of cold weather and unexpected power station shutdowns.

Sustainability:

Interconnectors allow countries to look beyond their borders and use renewable energy more efficiently. When it is sunny and windy in Great Britain, for example, where lots of power is generated, electricity can be moved quickly to a country where it’s needed. When British conditions are less favourable, power can be imported from Europe.

    Stubbington Lane and Crofton Avenue Road Crossings

    In preparation for the installation of the ducts for the cables, we are now making temporary changes to Stubbington Lane and Crofton Avenue.

    Our work will consist of digging below the roads to carry out the excavation of trenches and joint bays, installation of ducts for the cables in the trenches, backfilling and reinstatement, allowing us to be able to pull through the cables when they arrive onshore later this year and not disturb these roads again.

    On the 28th January 2019 we closed a section of Crofton Avenue where it meets Stubbington Lane. We have put in place a diversion down Sea Lane to maintain access to nearby homes and Monks Hill beach car park. Whilst the construction activities along Crofton Avenue will only take approximately a week, in order to better manage the traffic on Stubbington Lane the diversion will be in place until 24th February 2019.

    On the 4th February 2019, we also closed one lane at a time of Stubbington Lane for a three-week period. 

    Upon completion of this work, the construction areas will be reinstated and no equipment will be visible above the ground. We have worked closely with Hampshire County Council to schedule as much of this work as possible to fall outside the school term period.

    Regular updates will be provided on a weekly basis as this work progresses. Thank you for your continued cooperation. For further information, please contact us on 0800 0194 576 or email info@ifa2interconnector.com

    Portsmouth University students begin work experience for IFA2 project

    In late 2018, National Grid IFA2 welcomed students from Portsmouth University to carry out a business consultancy project within the IFA2 project as part of their degrees, the IFA2 Employment and Skills Plan and the ongoing commitment to engage with the local community. Joining the IFA2 project team in November 2018, five business undergraduates were tasked with two projects targeted around the work due to take place at Monks Hill Beach and the delivery of the public open space north of Daedalus Airfield, whilst applying knowledge that they have learnt throughout their time at the university.

    Joining the IFA2 project team in November 2018, five business undergraduates were tasked with two projects targeted around the work due to take place at Monks Hill Beach and the delivery of the public open space north of Daedalus Airfield whilst, applying knowledge that they have learnt throughout their time at the university.

    With the first of the two projects now complete, students have designed a series of panels, which will be transferred onto site hoardings highlighting the work that is scheduled to take place at Monks Hill Beach; where both the HVAC and HVDC cables will come onshore. Given the public nature of these works, the students also needed to explain various health and safety signs and symbols to inform members of the public to keep safe around the IFA2 construction site.

    Returning in 2019, the students will then begin their next project, supporting the delivery of the public open space.

    David Luetchford, head of IFA2 said: “We are thrilled to have students from Portsmouth University working with us on the IFA2 project. Ensuring that our site hoarding is both informative and educational for the local community is vital for us to meet the expectations of Fareham Borough Council. We are committed to delivering an appropriate level of communication and community engagement with the various stakeholders and members of the local community who use this public space.

    At National Grid, we are always looking for new opportunities to engage local students in the different types of careers and work experience opportunities that National Grid offer. For more information please contact: info@ifa2interconnector.com.”

    One of the students from Portsmouth University said: “We have thoroughly enjoyed our time so far working with the IFA2 project team. The experience has given us a real insight into how to apply our university learning into real business consultancy scenarios.”

    IFA2 contractors go carbon neutral!

    Working with its contractor I&H Brown, National Grid IFA2 has announced that the carbon impact for the new public open space will be neutral.* As a socially responsible civil engineering organisation, I&H Brown pride themselves on reducing their environmental impact by counteracting its greenhouse gas emissions through a long-term forestry project. Where managed on a long-term basis, forests are seen as greenhouse gas sinks for carbon sequestration purposes.

    As a socially responsible civil engineering organisation, I&H Brown pride themselves on reducing their environmental impact by counteracting its greenhouse gas emissions through a long-term forestry project. Where managed on a long-term basis, forests are seen as greenhouse gas sinks for carbon sequestration purposes.

    The Open Space Development’s carbon footprint and emissions will be offset by planting a mixture of trees in the 620-hectare forest which I&H Brown maintains offsite, in addition to the planting on the Open Space Development (link older article). Since 2013, I&H Brown estimate that through woodland management, they have had an annual footprint offset of -3,950.50 CO2e per year.

    The work being carried out by I&H Brown at the IFA2 site includes the reuse of ~36,000m3 of soil on site. This soil is being used to create the numerous earth bunds that screen the converter station buildings, as well as providing viewing platforms over sections of the Solent Airport.

    David Luetchford, head of IFA2 said: “Our new open space contractor is working hard to deliver the public open space at the Daedalus site. We’re pleased that in partnership with I&H Brown, we will be able to deliver a public open space that has a neutral carbon impact.

    Work is progressing well, and we’re now working to enhance the connectivity of the site by establishing the various footpaths and cycleways throughout the space for the public to enjoy in the future.”
