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 will involve 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?

  • In October 2018 until February 2019 we will begin digging the trenches to install the ducts for the cables. These will be completed in 50 -100m sections.
  • We have now completed the trenching for 1/3 of the route at the Airfield. 
  • We will shortly be moving down to the south end of the Airfield to continue our trenching activity.  

 

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.

To get into the airfield, the cables will need to cross Stubbington Lane and Crofton Avenue. To do this, a temporary lane closure will be necessary to install the cable ducts. This will not result in a full road closure and it will be timed to minimise disruption. The road surface will be reinstated immediately after completion of this work.

What are we doing in the next three months?

  • We are currently carrying out survey work at Monks Hill beach. This survey work is necessary in advance of our main onshore construction activity taking place in early 2019.
  • In December 2018, we will be holding an information event to present our construction programme for working at the beach.

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?

  • Following the completion of our cabling laying preparation work we will be leaving the Chilling site at the end of September and will not return until March 2019.
  • We have now completed the road crossings on Chilling Barn and Chilling Lane. We will shortly commence the crossing on Workmans Lane. This will not impact the public access ways.
  • Our site will be shut down to minimise disruption for overwintering birds. However, our partners, National Grid Electricity Transmission (NGET), will remain at Chilling.

    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.”
