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

HVAC Cable

IFA2 is in the process of installing six HVAC cables. A specialist cable laying barge, the NP 289, will lay one cable at a time in an eastern direction from Chilling to Monks Hill Beach.

The table below sets out the planned position of the NP 289 between 19/07/19 and 23/07/19.

Please note that the estimated position is subject to progress of lay which will depend on weather conditions. We will update you regularly on the cable lay progress.

The barge uses four anchor positions to move. These will constantly change as the barge moves forward. The position of each anchor is marked with a yellow buoy. To ensure the safety of beach and marine users, the four yellow buoys mark a safety exclusion zone. The safety exclusion zone is marked indicatively on the graphic above.

The barge is constantly moving and therefore the safety exclusion zone around it will also move.

Anchor cables run from the barge under the water to each of the four anchor points on the sea bed.

The anchor cables are up to 1000m long and could be tense or slack. The anchor cables are a hazard to marine users and for your safety it is important to remain outside of the safety exclusion zone marked by buoys.

There are two safety vessels supporting the works to help and guide water users. To ensure everyone’s safety please follow the guidance of the safety vessels.

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.
  • We are completing trenching works and installation until the end of June. 
  • The NP 289 barge is laying HVAC cable between Chilling and Monks Hill beach, as above.
  • Our cable laying barge the NP 289 will be completing the installation of the next HVAC cable by pulling in the end of the cable through pre-installed ducting at Monks Hill beach (between the car park and The Shack café at position E in the graphic above). The installation is due to take place on 21/07/19 over the course of daylight hours.
  • We are floating cable from the NP 289 barge into the water supported by orange floats, which should be clearly visible on the water. Additional safety boats will be on the water for the duration of this delivery to help divert marine users from the floating cable.
  • 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?

  • The HVDC cable laying activity will resume in the Summer months.

    Hook information event

    We’ll be restarting work to install cables for IFA2 in the Chilling area and are hosting an information event where you can find out more about this. The open event will take place from 4pm – 8pm on 12 March 2019 at the Nook and Cranny, Hook Ln, Hook, Warsash SO31 9HH.

    The open event will take place from 4pm – 8pm on 12 March 2019 at the Nook and Cranny, Hook Ln, Hook, Warsash SO31 9HH.

    Last year we installed the ducts which will house the high voltage alternating current (HVAC) cables required for IFA2. We then paused work in November 2018 to reduce the risk of disturbing overwintering birds.

    The season for these birds will soon be over, and we are preparing to begin work in the area again in coming weeks. The focus for our work will be laying and connecting the cables. As before, we’ll impose a 10mph speed limit for construction vehicles through Hook Village, as well as escorting any HGVs.

    Stubbington Lane and Crofton Avenue reopened to traffic

    National Grid IFA2 has been working to install cable ducts under Stubbington Lane and Crofton Avenue. As this work is now complete, we are in a position to reopen these roads to traffic. Stubbington Lane has been reopened, and Crofton Avenue will be reopened to traffic later in the afternoon of 1 Marc 2018. We are grateful to local people for their ongoing patience and cooperation during this work.

    IFA2 electrifies students with ‘Mad Science’ assembly

    In February, pupils from Lee-on-the-Solent Junior School were paid a visit by representatives from IFA2, along with a couple of ‘Mad Scientists’ in an exciting presentation about electricity.

    In February, pupils from Lee-on-the-Solent Junior School were paid a visit by representatives from IFA2, along with a couple of ‘Mad Scientists’ in an exciting presentation about electricity.

    As part of their commitment to the local community, IFA2 the organisation that is connecting England’s and France’s electricity supply via subsea cable - are encouraging pupils from across the area to engage in STEM subjects via a series of assemblies and workshops on electricity.

    With over 200 children in attendance, IFA2’s Assistant Commercial Manager Craig Hunter and Project Manager Joe O’Loghlen, started the session with a talk about careers in engineering.

    The Lee-on-the-Solent pupils were then joined by Super Sian and Electric Eddy from ‘Mad Science’ who presented a fun-filled interactive assembly. The assembly included quizzing the children on electric currents, famous electricians and getting some trusty volunteers to demonstrate how static electricity works on a Van de Graaff generator.

    Craig Hunter, Assistant Commercial Manager at IFA2, said: “As we continue to work on the IFA2 project, we feel it’s important to inspire children living in the area about the importance of electricity and STEM subjects.

    “We are looking forward to getting more local schools involved in the Mad Science workshops which will be offered as part of the programme.”

    Darren Nickerson, Headteacher at Lee-on-the-Solent Junior School, added: “The children really enjoyed having the ‘mad scientists’ in school. It was great to see them engaging with a topical subject that’s relevant to the area. It is vital to inspire our next generation on future prospects and the assembly did it perfectly.”

    Following the Mad Science assembly, the pupils took part in workshops to learn more about electricity. The workshops consisted of an in-depth session on electricity, constructing electricity circuits to demonstrate how electricity works as well as making a static electricity chain via the Van De Graaf generator. The programme is free and any primary school in the area is invited can take part.
