East Anglia TWO Public Information Day - 26th February 2026, Friston Village Hall

ScottishPower Renewables held a Public Information Day at Friston Village Hall on 26th February 2026.

The event focused on the ongoing and upcoming works related to the construction of the platforms for the East Anglia TWO and East Anglia ONE North substations.

ScottishPower Renewables is also carrying out the platform works for National Grid’s Kiln Lane substation and were joined on the day by two members of their team, to support with any questions on their future works.

There was also information on traffic management, landscaping and ecology.

For those who were unable to attend the event, or who wish to review the information shown, please find below all the materials displayed on the day.

All information is correct at time of print.

Background

East Anglia TWO (EA2) and East Anglia ONE North (EA1N) were each awarded a Development Consent Order (DCO) in March 2022. Each DCO granted consent for the development of an offshore windfarm and associated infrastructure.

This infrastructure includes two new onshore substations, one for each project, and construction is due to start on site this March. 

A new National Grid Electricity Transmission (National Grid) substation, known as Kiln Lane, is also to be built, with construction expected to start this Summer. Kiln Lane was consented as part of the EA2 and EA1N DCOs but will be constructed by National Grid.

The below figure (from 26th February 2026) shows all three sites together with the temporary construction compounds (CCS) for SPR and National Grid, towards the west of the site.

Commencement

Works will commence with vegetation clearance in required areas, followed by the realignment of existing ground levels, to create a level platform, upon which the substations will be built.

No material is being removed from site, with any excess being used to create bunds landscaped at various positions around the site to provide screening.

Stone will be imported into all three works areas via the previously built temporary haul road and will be compacted to form a solid platform for subsequent works. To avoid contamination, only virgin stone will be used.

Piling to various depths will then take place, to create a solid foundation for the infrastructure.

New and re-configured drainage, designed to manage both ground and surface water around the site, will also be installed. This water will be managed and diverted into a new permanent infiltration pond being constructed adjacent to the substation footprint for all three locations.

Landscaping, including planting, will form part of the works to enhance the area and for screening purposes.

Please refer to boards around the room for more details on the above topics.

Public Rights of Way

Work continues with diverting existing Public Rights of Ways (PRoWs) and creating new ones on and around the site. Photographs of the progress are shown below.

Footbridges over existing ditches are due to be installed over the coming weeks.

Please click the link below to view the photos of our recent PRoW works in a separate document:

Earthworks

Earthworks will entail the stripping of soil and levelling of the entire site, in preparation for stone works to follow.

We expect this period of works to last approximately three months, from March-May.

Topsoil stripping will be carried out before cut/fill earthworks and is to be used for landscape mounding around the site.  Topsoil strip depth will be approximately 0.31 meters.

This will result in levels across the site in line with the following:

Platform
Finished Earthworks level (above sea level)
Finished platform level (above sea level)
East Anglia TWO 18.4m 19.2m
East Anglia ONE North 17.9m 18.7m
NGET Substation Handover levels to vary: 17.75-17.9m Finished platforms will vary

Towards the end of this period, stone works are likely to commence in areas of the site where soil stripping is complete.

To level the site, the below figure shown on 26th February, shows land in red where earth will be removed and land in green where earth will be deposited.  No earth will be removed from site.

Excess earth will be used to create bunds to provide screening.  These will be planted with a mix of native species.  Please see the landscaping section for more information.

Drainage

Drainage testing continues across the site, before surface water and land drains are installed after the levelling works and before stone works commence.

An existing drainage ditch is being diverted to ensure it continues to operate in the same way as it does today.

Sustainable Drainage System (SuDS)

A Sustainable Drainage System, or SuDS pond, is to be created on site.

This will provide a more complex and biodiverse habitat, dramatically increasing the species richness found in the area.

Below is a photo of the SuDS pond on site taken in January this year, showing the early stages of construction.

 
Below is a photo of the SuDS pond built by SPR for the East Anglia ONE substation, which is now flourishing.

The SuDS drainage basin is designed to withstand an influx of 45% above a 100-year storm event, for rainwater across the entire site.

Temporary construction compound

Construction of our temporary construction compound has now been completed. Our contractors Taylor Woodrow are now primarily based at this compound.

This compound will remain in place until the projects are completed. After which, it will be removed, and the land will form part of the landscaping scheme. Below are images of the new compound.

 
 

Piling works – Continuous Flight Auger (CFA) method

Conventional piling methods consist of drilling a hole down to the required depth, then inserting a pre-cast concrete column into the hole. This is then hammered into the ground by a large diesel hammer.

By using the CFA (Continuous Flight Auger) method, a similar pilot hole is drilled, then the contractors insert a wire reinforcing mesh around the drill and pump concrete down the centre. They then slowly lift the drill out, filling the hole as it retracts.

This process takes slightly longer but we have chosen to use it because it is considerably quieter. 

This process will commence following the stone works. The earliest we expect it to start will therefore be around May.

Traffic management

Approved routes

This map shows the approved highways and routes our projects’ HGVs can follow, to and from site.

If you observe an SPR-signed vehicle in your area not on these routes, please contact eastangliatwo@scottishpower.com, sharing the unique identifier sticker, number plates, and type/make/model of vehicle wherever possible. Our Community Liaison Officers can then escalate this to the Transport Team, who will use Datascope to verify whether the vehicle is associated with our projects, and take necessary actions if a breach has been identified.

Identifying Heavy Goods Vehicles (HGVs)

 
The above sticker will be displayed on every HGV coming to and from our site. Each one will have a unique number, allowing us to identify it and its driver. We can then action any queries and reduce further issues promptly.

Tracking and logging HGV movements

 
All HGV movements are recorded by our Traffic Management Coordinators, via a database called Datascope. This information is also supplied to Suffolk County Council on a quarterly basis, who oversee our works to ensure they are compliant with the projects’ Development Consent Orders. This software provides further assistance with the identification of vehicles, should it be necessary to do so.  Above is an example screenshot from the software.

Example plant

Please click the link below to see examples of some vehicles and equipment to be used on site.

Ecology

Shown on 26th February was a board highlighting some of the wildlife our Ecology Team has already pictured on site. To view these photographs, and accompanying information, please click the link below:

Ecological buffer zones

These are used to protect wildlife and their habitats from disturbance or harm during construction. Areas identified on site are fenced off at distances decided by qualified ecologists and based on recommended guidance from Natural England. The size and duration varies according to species. Signs are used to notify people that entry into these areas is not permitted.

Habitat creation

We have created artificial badger setts, like the one pictured above, to entice badgers away from our red line boundary. Badgers are strictly protected under the Protection of Badgers Act 1992. Therefore, such works are carefully monitored under licences from Natural England. For these reasons, we are unable to share the locations of known natural setts, or artificial ones we have implemented.

The below graphic shows what environmental enhancements are being made across the site:

Roles on site

There are a variety of roles and responsibilities within our Ecology Team, who are regularly out on site, checking works are compliant. They include:

Role
Duties
Ecological Clerk/s of Works (EcoW) Responsible for monitoring known ecological features and identifying new ones throughout the project and providing advice on legal wildlife protection compliance.
Arboricultural Clerk/s of Works (ArbCoW) Responsible for monitoring works around trees and hedgerows, implementing protection measures throughout the project.
Environmental Advisor/s Work with ECoWs and ArbCoWs to coordinate supervision and communicate advice. Responsible for environmental compliance with commitments such as noise levels, dust volumes, carbon usage and waste management.

Environmental Manager/s

 Responsible for maintaining compliance across all areas of the project and providing reportable data for local authorities and governing bodies. 
Supervisor/s Agricultural Liaison Officer/s (ALO) - Soil specialist
Agricultural Liaison Officer/s (ALO) - Soil specialist Responsible for ensuring good soil management to maintain suitable conditions for crops and plants to grow following the full reinstatement of the project. 

Landscaping

At the event on 26th February, we showed the below viewpoints of the site from Friston Church. These included the existing view, then subsequent views after the substations are constructed, including the growth of vegetation after two, five, seven, 15 and 17 years.

Also shown on the day were the high-level landscaping plans for the site. These include an illustrated masterplan (below), followed by a more detailed diagram, labelling the buildings on site and the different stages of planting to be created.

Monitoring and mitigation

Dust monitoring

Significant amounts of dust can be caused by construction traffic during drier months. This can be monitored both visually and using specialised equipment. Minimising movements across dusty areas is prioritised but when required, spraying water on the affected ground can work as a dust suppressant. This is done sparingly, and alternative waters sources are preferred to potable water.

Root protection zones

Several trees and hedges can be found within the East Anglia TWO working area. We leave as many as possible in place. To protect those remaining on site, fencing is erected around them at a distance that is informed by a trained arboriculturist. Signage is also used to notify people that entry into these areas is not permitted. Trees and hedges that cannot be retained will be reinstated or replaced at the end of the project, maintaining long-term biodiversity.

Vibration monitoring

Vibration monitoring will be undertaken throughout construction to ensure any disturbance is minimised.

Operatives will be subject to restricted working hours and required to use mufflers and silencers to protect themselves and lessen any impacts on the local community.

Noise monitoring

Noise monitoring will be undertaken regularly to ensure it is compliant with the Development Consent Orders (DCOs). Similar to vibration monitoring, other techniques will be implemented to reduce noise where possible, for example, starting plant engines sequentially and using noise barriers around busy work locations.

Pollution prevention

Around the site there will be numerous spill kits to control any spillages, and all staff are trained in how to manage such incidents. In addition, all plant will have a spill kit on board as well as an absorbent pad that will be placed under the vehicle at the end of use.

East Anglia TWO Public Information Day – 5th June 2025, Knodishall

ScottishPower Renewables held a Public Information Event on Thursday 5th June at Knodishall Village Hall to provide information on upcoming construction works related to the East Anglia TWO.

Ecology

Below is the information provided at the Public Information Event.

Surveys of birds such as skylark, nightjar and woodlark have been undertaken across the entire cable route throughout the breeding bird seasons within the pre-construction phase and we will continue to monitor activity while contractors are on site. 

An Ecological Clerk of Works (ECoW) will be on site to check for nests and oversee activity during construction.  Should any nests be found, they will be marked and protected until the chicks have fledged. Wintering bird surveys and targeted Schedule 1 bird surveys have also been carried out.

Ecological mitigation has already been carried out, including habitat creation/scrub planting to create habitat for nightingale and growing of a seed mix to provide food for turtle dove, and supplementary feeding of turtle dove, which will continue throughout the construction phase.

Habitat creation, including additional scrub planting and wildflower sowing, as well as scrape creation, has also been carried out. Barn owl boxes have also been installed at suitable locations within the development area.

Surveys of badger setts and badger activity have been undertaken across the entire cable route throughout the pre-construction phase and we will continue to monitor activity while contractors are on site. The cable route has been designed to avoided impacts to badger setts where possible. Licences have been obtained from Natural England to close setts where impacts are unavoidable, with an artificial sett constructed to replace lost habitat.  An ECoW will be on site to supervise all works close to active badger setts and check for any new setts.

 

A District Level Licence (DLL) has been obtained from Natural England for Great Crested Newts (GCN). The DLL enables  offsite compensation to be undertaken by Natural England appointed contractors which correlates to the level of impacts of the works.

Reptile surveys have been carried out within suitable habitat across the entire cable route. Good practice measures for amphibians and reptiles will be followed while contractors are on site, these will be enforced by the ECoW.

Vegetation clearance within suitable habitat will be preceded by a pre-works search by the ECoW, with any captured reptiles or amphibians relocated to a suitable location. Additional mitigation at areas with higher reptile populations or areas with possible GCN presence will include two-stage vegetation cuts and exclusion fencing.

Bat activity surveys and aerial roost inspection surveys have been carried out in order to identify high value bat commuting and foraging habitat and bat roosts within trees. Hazel hurdles will be installed across any gaps in high value hedgerows in order to ensure commuting routes are not disrupted. In addition, a licence from Natural England will be obtained if any trees with confirmed bat roosts require removal, and compensatory bat boxes will be installed to replace any lost features. Fifty additional bat boxes have already been installed on site as an enhancement measure.

Scoping Report

As part of the consenting process we submitted Scoping Reports for East Anglia TWO and East Anglia ONE North to the Planning Inspectorate (PINS) for their consideration in November 2017. These Scoping Reports requested a scoping opinion to agree the methodology for undertaking the full Environmental Impact Assessment (EIA). These assessments form part of the Environmental Statement which will be submitted as part of the full Development Consent application.

The Scoping Reports provided a clear description of our proposed infrastructure, and connection route to the electricity transmission network. The scoping process also sought stakeholder opinions on the areas to be investigated in detail when undertaking our Environmental Impact Assessments.

Statement of Community Consultation

In accordance with Section 47 of the Planning Act 2008, East Anglia TWO Limited published a Statement of Community Consultation in March 2018 outlining our approach to consulting with local communities on the East Anglia TWO offshore windfarm.

In September 2018 ScottishPower Renewables published an Updated Statement of Community Consultation to include an additional phase of consultation (Phase 3.5) that took place from 29 September to 12 November 2018.
