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.

    Major milestone for IFA2 as first UK converter station buildings erected

    November sees a major milestone for IFA2 as the first steel structures start to be erected at the UK converter station site.


    The main work contractors ABB are working with Morgan Sindall who are overseeing the civil phase of the build.

    The steel structures, which will be erected over the coming months, will be the first visible structures at the site. In time, they will house the key elements of the converter station including the AC & DC electrical equipment and form the control building.

    Once the structures have been erected, contractors, Morgan Sindall will weatherproof the buildings. Internal fit out and the installation of transformers is due to take place later in 2019.

    Dave Luetchford, head of National Grid IFA2, said:

    “To date, all our work on the converter station has taken place behind the site hoarding. It’s great to see the converter station now taking shape.”

    For further information about work at the converter station site, please contact National Grid IFA2 on 0800 0194 576 or info@ifa2interconnector.com

    Broom Way construction

    We wrote to residents of the Lee-on-the-Solent area on 29 May 2018 to inform them that we anticipated closing one lane of Broom Way to traffic for five days from 11 June 2018 while we created a new access to the converter station site. We are now no longer planning to carry out this work in this period. This will now be rescheduled to a future date. We are grateful to members of the community for bearing with us, and will provide an update on the rescheduled work in due course.
