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.


Estimated Position











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 tool below.

What will happen in the next three months?

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

    Tree planting marks the start of open space for IFA2

    National Grid IFA2 Ltd marks the beginning of the creation of the public open space with a ceremonial tree planting event.

    National Grid IFA2 recently commenced the beginning of construction at the IFA2 site by inviting Fareham Borough Council leader, Cllr Sean Woodward, and other community representatives to mark progress and take part in a ceremonial tree planting event. 

    In partnership with Fareham Borough Council, it is anticipated that over 30,000 native trees both new and mature, will be planted to create an enhanced habitat across the space and appropriate screening to the north and east of the converter station. This is the start of National Grid IFA2 providing 38 acres of public open space as part of its commitment to the local community. 

    IFA2, which received planning permission last year, will be a high voltage direct current (HVDC) electrical interconnector linking the British and French transmission systems. Once operational, IFA2 will be capable of exporting or importing 1000MW of power between the two countries, enough to power around 1 million homes. 

    David Luetchford, Head of National Grid IFA2 said: “It was great to welcome Cllr Woodward and other local representatives to the IFA2 site yesterday to mark the start of construction. We are making a major commitment to the local community: we’ll deliver over 38 acres of open space for local people to enjoy, and we’ve signed up local companies to support this work. We look forward to working closely with the Council over the next two years to create this new resource for the community.” 

    Leader of Fareham Borough Council, Cllr Sean Woodward added: “It was an honour to plant the first tree here. The Council has always been keen for a large area of public open space to accompany construction of the Interconnector, so it’s great to see this coming to fruition and I look forward to it being open for residents to enjoy.”
