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.

    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.

    Update on work at Crofton Avenue and Stubbington Lane

    We are currently working to install ducts for the IFA2 interconnector cables under Stubbington Lane and Crofton Avenue. We originally expected this work to be complete by 24 February 2019. Unfortunately, work is taking longer than expected due to the need to dig around additional underground utilities services. We’re afraid this means that we need to keep the traffic management in place until Sunday 3 March on Stubbington Lane and until Sunday 10 March on Crofton Avenue. We are very sorry for the continued inconvenience this will cause you. We have increased the managed traffic periods at peak times to help minimise delays where possible. Thank you for your continued cooperation. For further information, please contact us on 0800 0194 576 or email info@ifa2interconnector.com.
