Eastern Green Link 3

To meet the requirements of increasing renewable energy generation multiple projects are being developed by SSEN Transmission and others are being jointly developed with between SSEN Transmission and National Grid. Extensive system studies have been completed to inform the ESO’s ‘Pathway to 2030 Holistic Network Design’, confirming the requirement to develop new direct connections between the networks in Scotland and England.​

To transfer the renewable power generated in the North of Scotland to demand centres in the South a 525kV HVDC link, via a subsea cable from Peterhead to the Lincolnshire area is required and will be known as Eastern Green Link 3.  ​

The Eastern Green Link 3 project will use the latest technology to provide a  2GW bi-pole, 525kV HVDC link between Peterhead in Aberdeenshire and the Lincolnshire area in England. This will enable the efficient transmission of high volumes of power which can then be further distributed to demand centres throughout the UK.​

At each end of the HVDC link, 400kV AC substations will supply power to (or receive power from) newly constructed high voltage AC/DC converter stations at Peterhead and Lincolnshire, depending on the directional flow of power. Consultations for the converter station sites have begun and future consultations will be held in 2024.​

Connections between these assets will be via HVDC cables buried either  underground or below the seabed. In Peterhead, the land cable corridor could stretch up to 12km between the Peterhead Net Zero 2030 Development site and the associated landfall. The cables will also pass through a neighbouring HVDC switching station which will provide further resilience to the network. The subsea cable route is currently being developed, including making a final  determination of preferred landfalls in Scotland and England however the subsea cable may cover up to 550km before making the transition back to land cable again. The length of the land cable corridor to grid connection in England will also depend on the final landfall location.​

Community Engagement

Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing. This is particularly important when we are developing a proposal and we want to understand what local people think about our plans.We endeavour to take the time to discuss proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive. We will do our best to answer any questions and address issues or concerns that are raised with us.

When our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.

How we’re embracing artificial intelligence (AI)
We intend to use AI to assist our experienced teams in the analysis of your feedback, so we can categorise key points raised more quickly. You can learn more about how we’re utilising AI on this dedicated web page.

    Report on Consultation

    Our Reports on Consultation across our three new overhead line projects and associated substation and convertor station developments have now been published. These reports provide a summary of the extensive feedback received during consultation, how this has been considered and confirmation of which routes and substations are now being taken forward to the next stage of development. 

    Our Reports on Consultation are now available to download from the Project Documentation tab. 

    Summary Reports on Consultation are also available for each of the three schemes and can be downloaded below:  

    A stakeholder webinar available for all to join will be held in the coming weeks to share the changes informed by the feedback. More information about the forthcoming webinar will be shared on our events page shortly.   

    In further recognition of community feedback, we will seek to rationalise cumulative infrastructure impacts through the removal and undergrounding of existing transmission lines, where technically practical and appropriate, and subject to all necessary planning consents and landowner agreements. 

    Work to identify and assess potential sections of existing overhead line where their removal will reduce cumulative impacts is ongoing, with an update expected as part of the next round of public consultation on overhead line alignments and more detailed substation designs in early 2024.  

    We would once again like to thank all stakeholders who took the time to engage with our early consultation process. We will continue to engage with stakeholders ahead of consulting further with local communities and stakeholders in the new year, as we look to refine our proposals.

    Report on Consultation

    Over the course of this year, we have undertaken extensive consultation on plans to upgrade the electricity transmission network across the north of Scotland and have received a considerable amount of feedback from a wide range of stakeholders regarding our proposals. 

     

    We recently advised in our next steps for 2030 network developments update that following assessment of consultation feedback and additional options analysis, we would publish our Report on Consultations (RoCs). These reports provide a summary of the feedback received and how it has been considered, which options we will take forward to the next stage of the development process and any changes to options initially consulted on.  

     

    It is our intention to publish the RoCs during the week commencing 27 November. All stakeholders signed up for updates on the project will receive a link to the report and we will also issue Summary Reports to help ensure accessibility. 

     

    These Report on Consultations mark the completion of the first round of non-statutory consultation, where we sought feedback on the corridor, route, and substation locations. We will be consulting further with local communities and stakeholders in the new year, as we look to refine the projects, therefore we welcome an open channel of communication and would like to reassure all stakeholders that there will be further opportunities to engage on this project.

    Our Reports on Consultation and Summary Reports on Consultation are now available to download from the Project Documentation tab.
