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.

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?

  • Monks Hill Car Park reinstatement work is now complete.

  • The beach and car park have been returned for public use.

 

Final stages of car park reinstatement work.

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.

Reinstated speed bumps at the Chilling site.

What are we doing in the next three months?

  • Our work in this area is now complete. Thank you for your patience during the construction and reinstatement work.

    Supporting our vulnerable neighbours

    National Grid IFA2 aims to be a considerate and supportive neighbour to the local community and, like so many across the country, we have felt this even more keenly during these extremely challenging times.

    National Grid IFA2 aims to be a considerate and supportive neighbour to the local community and, like so many across the country, we have felt this even more keenly during these extremely challenging times.

    Our team has been eager to support key workers, the elderly and the vulnerable. We have therefore been delivering local donations of PPE in recent weeks – reaching nearly 40 care and nursing homes in the areas of Fareham, Gosport and Lee-on-Solent.

    Face visors, face masks, sanitiser, antibacterial wipes, gloves, scrubs bags and gowns have made up the bulk of our donations. Initially, items were from stock supplied to our construction sites and our office at the Innovation Centre. However, as we began to appreciate the scale of the problem and the stress it was causing, we began to purchase supplies for donation via our own procurement channels, specifically to meet the local need.

    We have fortunately been able to make multiple visits, whilst observing social distancing protocol, to those organisations most in need of urgent supplies and unable to source them through traditional channels.

    Over the coming weeks we are hoping to continue this small contribution for the key workers who are so bravely delivering essential care in our local communities.

    We are extremely grateful for the efforts of everyone in the care homes, locally and nationally, the NHS and all key workers as they continue to work through these difficult times.

    IFA2 update: COVID-19

    The COVID-19 pandemic is unprecedented, along with the measures in place to limit the outbreak further. Therefore, impacts on the programme may occur but we cannot be certain at this stage of the health crisis.

    The COVID-19 pandemic is unprecedented, along with the measures in place to limit the outbreak further. Therefore, impacts on the programme may occur but we cannot be certain at this stage of the health crisis.

    Once the consequences of the crisis are better known, including updated social distancing measures, the IFA2 Programme will undertake a detailed impact assessment. Communications will follow as appropriate.

    Both RTE and National Grid commit to minimising the impacts, whilst respecting the social distancing measures, and commits to protecting the security and health of everyone working on the project.

    COVID-19 and IFA2 construction work

    The two partners, National Grid and RTE, together with our contractors, have assessed and continue to assess the impact of COVID-19 on the construction works in both countries. In line with current government guidelines in the United Kingdom and France, essential work on the IFA2 interconnector project continues.

    The construction of IFA2 is a key part of the development of national infrastructure for the UK and France. The two partners, National Grid and RTE, together with our contractors, have assessed and continue to assess the impact of COVID-19 on the construction works in both countries. In line with current government guidelines in the United Kingdom and France, essential work on the IFA2 interconnector project continues. Some of the activities are works that need to take place today, to ensure the running of the network tomorrow.

    The welfare and safety of our employees, contractors and the local community remains our priority.  All of the people who need to continue working on site and in the community, are doing so under stringent health and safety measures to protect not just themselves but also the communities in which we operate.

    We are very grateful to our people who are continuing to go out to work every day to continue the construction of the energy networks of tomorrow at such a critical time.
