Nautilus Interconnector: Public Consultation 

As you may be aware, National Grid Ventures is bringing forward proposals for Nautilus Interconnector close to Leiston in East Suffolk. This new multi-purpose interconnector would enable the connection of up to 1.4 gigawatts (GW) of offshore wind in the UK and Belgium (with a total of 2.8 GW), powering up to 1.4 million homes in the UK and 1.4 million homes in Belgium. 

By combining offshore wind generation with interconnector capacity between the UK and Belgium, Nautilus would significantly reduce the amount of infrastructure and disruption required in both the marine and onshore environment. With this change in technology, we would also be able to reduce the impact on the affected communities and environment, as well as support the UK achieve its targets for Offshore Wind and Net Zero. We are already working closely with the other developers in the area in order to coordinate our activities and minimise the impacts on the local communities. We believe that through improved coordination, the UK government can achieve and support the co-existence of renewable energy with coastal communities.

The project team at Nautilus have been engaging with Local Authorities and Parish Councils since 2019, and on 14 September we will be launching a public consultation, which will run for six weeks, closing on 26 October. Our consultation will feature both face-to-face and digital engagement, including four community drop-in sessions in East Suffolk. 

In advance of this, we have produced a briefing pack. In this you will find some further details on our vision for Nautilus, our current siting and routeing options and how to get involved and provide feedback as part of the upcoming consultation.
