Increasing security of electricity supplies for both the UK and France.

HVAC Cable

IFA2 is in the process of installing six HVAC cables between Monk's Hill Beach and Chilling. This work has been progressing well, and we have now laid 5 of 6 cables.

We are now pausing the cable laying work between 9 August 2019 and 17 August 2019 to avoid the risk of causing disruption during Cowes Week. We will begin laying the sixth and final HVAC cable again on 18 August 2019.

What are we doing in the next three months?

  • The C57 Red Squirrel jack-up barge, is in position in the intertidal area off Monks Hill Beach. The working area for the barge is marked by buoys and is patrolled by safety vessels for your protection; please avoid this active working area.
  • The NP 289 barge is laying HVAC cables between Chilling and Monks Hill beach. We expect to complete all six cable installations by the end of August.
  • The HVAC cable lay includes a pull-in process at Monks Hill Beach which we expect to take place from the middle of next week, depending upon weather conditions. The pull-in involves floating cable supported by clearly visible orange floats from the NP 289 barge onto the water. The cable is floated from the barge to the shore at Monks Hill Beach where it is pulled into the prepared cable ducts. Additional safety boats will be on the water for the duration of this work to help divert marine users from the floating cable.
  • Once we have laid the HVAC cables, our HVAC burial vessel JIF ARTEMIS will begin to bury them beneath the seabed. We expect this work to last until November.
  • Our support vessel, GREEN QUEST, will be in the area assisting JIF ARTEMIS.
  • Please be extra vigilant in this construction area during the installation period. We are very grateful for your patience and cooperation.

HVDC Cable

The HVDC cables linking the electricity transmission systems of Great Britain and France are an essential part of IFA2. We will carry out the work to lay these cables in 2019.

The cables will be buried in the seabed. We’ll install the cables using large specialist vessels which are able to transport and lay long sections of cables (up to 100 km). Some cable joints will need to be made at sea during the installation process.

The current position of the HVDC cable laying vessel, the Cable Enterprise, can be tracked using the MarineTraffic.com tool below.

What will happen in the next three months?

  • Our vessel, IEVOLI AMBER, will begin surveying the deep water area from the end of August. We will also make a pre-lay grapnel run of the area.
  • Starting in early September our survey vessel WESSEX EXPLORER will begin surveying the nearshore area. 
  • The AETHRA burial vessel will begin route clearance work at the end of September. 
  • We will begin nearshore pre-lay works from our vessel WILLENDEAVOUR at Lee-on-the-Solent in September. These works will take place up to 2km from the beach.
  • We expect to begin laying the HVDC cable in mid to late October.

    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.

    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.

    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.”
