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

Onshore cables

  1. The HVAC and HVDC cables related to the converter station will make landfall at Monk’s Hill beach.
  2. We will lay HVDC and HVAC cables to and from the converter station along one of the runways at Solent Airport. We’ll start this work in October 2018 and finish in October 2019.
  3. The HVAC cables will run along the bottom of the Solent to Chilling. We’ll lay these in 2019.
  4. The HVAC cables will make landfall at Chilling.
  5. We will lay HVAC cables between the landfall and connection point at Chilling. We’re carrying out construction work here until September 2018, and then installing the cables in 2019.
  6. The HVAC cables will connect to the national electricity transmission system at a substation in Chilling.

Airfield

Our HVAC and HVDC cables will connect to the Converter Station, the route from Monks Hill Beach to the Converter Station involves the installation of the cables onto 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 will follow on from this work during spring and summer of 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 the offshore HVAC cables and are now burying them. 
  • To prepare for the arrival of the HVDC cables we are digging a trench in the intertidal area at Monks Hill Beach.

Monks Hill Beach

This is where both the HVAC and HVDC cables will come onshore. All work will take place within a compound in the eastern part of the car park. We’ll 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 are preserved throughout the construction period.

Our work will consist of the excavation of trenches to install the cable ducts, backfilling and reinstatement and the construction of 3 transition joint bays in the car park which will be backfilled and reinstated after completion of the jointing works.

When carrying out this work we will:

  • Ensure the working areas are safely segregated from the public
  • Complete the beach works and work within the eastern car park area within one season (2019)
  • 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?

  • Fencing is in place on the beach and pink buoys are positioned on the water around our jack up barges, the C57 Red Squirrel and C59 Emotion, to mark our working construction area. There are open excavations and obstructions under the water and the area is therefore restricted for your safety. Please do not enter this restricted working area on the beach or in the water. For more information please see the poster above. These vessels are expected to depart in WC 9/9/19.
  • The CAPALL MARA (shown below) will arrive on site shortly for trenching work associated with the HVDC cables. We will be working up to 2km from shore with the CAPALL MARA and will share further details shortly. The HVDC cable pull is scheduled for mid-October after CAPALL MARA has completed trenching works.
  • We have site hoardings around the area to the south of Crofton Avenue which is the main access for our construction traffic down to Monks Hill Car Park.
  • We have completed the installation of sheet piling off Monks Hill Beach. We aim to finish trenching work there by mid-September and will then return the beach to its original condition.
  • We have temporarily diverted the public footpath from the car park to The Shack café while we excavate trenches underneath the footpath route. The temporary footbridge in place as part of the diversion will be removed in WC 9/9/19.
  • We are burying the six HVAC cables between Monk’s Hill Beach and Chilling using the JIF ARTEMIS and GREEN QUEST (safety vessel). We expect to complete this work in November.
  • The current position of our vessels can be tracked on the MarineTraffic.comtool on the Offshore Cable section of this site.

Chilling

Chilling is the point that IFA2 will connect to the electricity transmission network. We are laying cables from the shore area to an existing National Grid facility on Chilling Lane.

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

Elsewhere, we will dig trenches, bury the ducts, reinstate the ground, and pull the cables through. In all cases, the cables will not be visible when we have finished. For further information on NGET and the work at Chilling please visit: https://www.nationalgridet.com/infrastructure-projects/ifa-2-connection 

Programme

To reduce the impact of our project traffic in the area we will do the following:

  • 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 the crossings over Chilling Lane and Workmans Lane.
  • We returned to site in mid-March after a shutdown period to protect overwintering birds.

    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.

    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.”
