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

Onshore cables

  1. The HVAC and HVDC cables related to the converter station make landfall at Monks Hill Beach.
  2. HVDC and HVAC cables run to and from the converter station along one of the runways at Solent Airport.
  3. The HVAC cables were laid in 2019 and run along the bottom of the Solent to Chilling.
  4. The HVAC cables make landfall at Chilling.
  5. We have laid cables between the landfall and connection point at Chilling.
  6. The HVAC cables connect to the national electricity transmission system at a substation in Chilling.

Airfield

Our HVAC and HVDC cables connect to the converter station via Monks Hill Beach and Solent Airport.

Work on the airfield during 2018 and early 2019 involved excavation of trenches and joint bays, installation of ducts for the cables in the trenches, backfilling and reinstatement. Installation of the cables and jointing works took place in 2019.

In October 2017, National Grid IFA2 undertook EMF trials on Solent airport. Using AC and DC cable systems installed and energised in the configuration and current rating reflecting the actual conditions in service. This was to verify compliance with the planning conditions and that there was no interference with aircraft avionics.

All participants, including airfield users confirmed that:

  • During the trials all aircraft systems functioned as normal
  • There were no anomalies observed on any of the aircraft avionics
  • Magnetic compass deviation was temporary and minor
  • For more information on Solent Airport please visit www.solentairport.co.uk

What are we doing in the next three months?

  • We have finished laying and burying the offshore HVAC cables and the HVDC cables.
  • We are working on seabed reinstatement following the cable burial.

Monks Hill Beach

This is where both the HVAC and HVDC cables come onshore. All work is taking place within a compound in the eastern part of the car park. We access this using a purpose-built haul road through a field to the north of the car park. This will mean full public access to the western part of the car park; the beach and the beach huts has been preserved throughout the construction period.

Our work included excavating, backfilling and reinstating trenches to install cable ducts and the construction of three transition joint bays in the car park which will be filled and reinstated when cable jointing work is complete.

When carrying out this work we will:

  • Ensure the working areas are safely segregated from the public.
  • Maintain access to the western section of the car park ensuring that access to all beach huts is maintained.

What are we doing in the next three months?

  • Work to reinstate the car park area will start at the end of March and should be complete by mid-April.

  • This work to return the car park to public use will be phased to release parts of the car park area as soon as they are completed.

Chilling

Chilling is where IFA2 connects to the electricity transmission network. We have installed cables from the shore area to the existing National Grid substation site on Chilling Lane.

We used a technique known as Horizontal Direct Drilling (HDD) to install cables in the shore area. This involved drilling underground and installing a series of ducts, which we then pulled the cables through.

Elsewhere, we dug trenches, buried the ducts, reinstated the ground, and pulled the cables through the ducts. The cables will not be visible when we have finished and the area will be reinstated.

For further information on NGET and the work at Chilling please visit: https://www.nationalgridet.com/infrastructure-projects/ifa-2-connection 

To reduce the impact of our project traffic we:

  • Impose a 10mph speed limit for construction vehicles through Hook Village.
  • Escort any HGVs moving through Hook Village.
  • Brief drivers about Chilling Lane’s use as a footpath and cycleway.

What are we doing in the next three months?

  • We have now completed work and reinstatement for this year in the Chilling area.
  • Due to bad weather and poor ground conditions we will need to return in Spring 2020 to complete a small amount of reinstatement.
  • We will not be mobilising a full site and will keep equipment to a minimum to complete this final work.

    IFA2 ‘Tops out’ at Daedalus Airfield

    Mayors meet to mark interconnector milestone

    Cllr Pamela Bryant, the Mayor of Fareham, and Olivier Paz, the Mayor of Merville-Franceville, unveil a plaque celebrating the completion of external construction of a building they are ‘proud to host’

    Cllr Pamela Bryant, the Mayor of Fareham, and Olivier Paz, the Mayor of Merville-Franceville, unveil a plaque celebrating the completion of external construction of a building they are ‘proud to host’

    National Grid and RTE’s IFA2 interconnector project marked an important phase in its ongoing construction programme last week when the mayors of the two communities where cables come ashore in the UK and France jointly unveiled a ‘topping out plaque’.

    The ‘topping out’ marks the completion of the external construction of the converter station building in the UK – an important part of the project that will link UK and French electricity transmission systems once operational.

    Olivier Paz, the Mayor of Merville-Franceville in Normandy, joined Cllr Pamela Bryant, the Mayor of Fareham, Cllr Seán Woodward, the Leader of Fareham Borough Council, and representatives of National Grid and RTE for the occasion.

    Cllr Pamela Bryant, the Mayor of Fareham, said: “At Fareham Borough Council, we take climate change very seriously and have set an ambitious goal of achieving net zero carbon emissions by 2030 through a range of initiatives including a credible carbon reduction plan. Although it is essential to take ambitious and sustained action locally, climate change will only be addressed if we work together with other countries. That is why at Fareham Borough Council we are proud to host IFA2 on land that we own.”

    Olivier Paz, the Mayor of Merville-Franceville, said: “We hope that this electric link will be the start of other exchanges in the future between our localities which share the same frontiers. Culture, sport, history, tourism, our administrations, are some of the subjects where, if you accept, our cooperation would be worthwhile.”

    David Luetchford, IFA2’s Project Director in the UK, said: “The electricity that will flow in both directions via IFA2 will increasingly be sourced from renewables in the UK, France and the rest of Europe. As part of a network of European subsea, clean energy super-highways, IFA2 will help to reduce Britain’s carbon emissions from the power sector - by 2030, 90% of electricity imported via National Grid’s interconnectors will be from zero carbon sources.”

    IFA2 is a 1,000 MW high voltage direct current (HVDC) electrical interconnector currently under construction between the British and French transmission systems. When it becomes operational later this year it will provide the capability to export or import 1,000MW of power.

    Inspiring our future workforce

    National Grid IFA2 recently supported ‘Get Inspired Portsmouth’, organised by the Education Business Partnership (EBP South). Over 1000 young people attended the Portsmouth Guildhall at the end of January to learn about the range of careers available to them on their doorstep.

    National Grid IFA2 recently supported ‘Get Inspired Portsmouth’, organised by the Education Business Partnership (EBP South). Over 1000 young people attended the Portsmouth Guildhall at the end of January to learn about the range of careers available to them on their doorstep. They were able to meet businesses from all industries who were there to inspire young people into their sectors through interactive activities.

    Craig Hunter from IFA2 said: “Promoting careers in STEM is really important for our organisation as we look to address the skills gap. Encouraging and inspiring pupils to become the ‘next generation of engineers’ is the only way that we will be able to achieve a greener grid. The opportunity to engage with 1000+ school children and get them thinking about how the skills they are learning in school today could lead them to a career in STEM is critical to the success of transitioning the UK’s energy supply to zero carbon sources.”

    National Grid IFA2 supported the EBP South’s Get Inspired events in both Portsmouth and Southampton this year to help give young people an opportunity to learn about the vast range of careers available to them on their doorstep and in the surrounding areas; and discover companies they may never had heard of.

    “There’s a strong tradition of employment here in Portsmouth and it’s well known the biggest influence on career choices is family. However, it’s vital that young people are aware of all the career opportunities out there,” said Cath Longhurst, CEO of EBP South.

    IFA2 looks to the skies to enhance safety

    IFA2 has worked with Daedalus-based company Flylogix on the development of an innovative solution for the coordination of offshore safety.

    IFA2 has worked with Daedalus-based company Flylogix on the development of an innovative solution for the coordination of offshore safety. The local technology and aviation business carried out Unmanned Aerial Vehicle (UAV) operations over the congested waters of the Solent and the Channel. Its mission was to provide live video of cable installation to help coordinate safety operations on the water.

    The UAV in the air

    Jake Stevens, IFA2 project manager, said: “We are laying interconnector cables in one of the most congested marine and aviation areas in the UK. In order for the works to be performed safely and minimise disruption we have looked at developing an innovative solution to help manage offshore operations.

    “To further support our safety vessels for this operation we have also worked with Flylogix, here on Solent Airfield, to include aviation and add a further dimension to our safety solution. Our aim was to develop a UAV real time image system to increase the monitoring of vessel traffic in area and to help ensure that the project can be completed without incident to the public or commercial water users.

    “We know that working with local businesses, such as Flylogix, can bring benefits to the project and also to the community. We were very pleased to be able to source the specialist expertise we needed right here in Lee-on-the-Solent.”

    Chris Tavner, Flylogix and Adrian Morris, IFA2

    Ed Clay, Flylogix's Operations Director, said: “The Solent is one of the busiest stretches of water around the UK with the convergence of heavy commercial, freight, leisure and fishing vessels coupled with challenging navigational features. The addition of our UAV surveillance capability further bolstered an already comprehensive maritime management operation for the IFA2 interconnector project.”
