Currently the project team are in the early stages of developing the wind farm and are considering the project design and infrastructure both onshore and offshore.

Electricity generated by the Five Estuaries Offshore Wind Farm will be brought onshore via subsea cables and reach the coastline at a point known as the landfall. The cables will then be laid underground along a cable route to an onshore substation close to the grid connection point. We have accepted a revised connection offer from National Grid for a new substation being referred to as the East Anglia Coastal Substation and it is anticipated that the Five Estuaries project will have one onshore substation. The Five Estuaries team and contractors are carrying out surveys for locating potential project infrastructure in the East Anglia Coastal area.

Similar to its sister project Galloper the wind farm will be in two fields.  The area of seabed it will cover will be up to 149km2 and will be 37km at its nearest point to shore. It is anticipated Five Estuaries may have two offshore substations.

As part of the survey work, we have liaised with different stakeholders. In relation to the offshore surveys, which are now completed, we engaged with local fishermen and held Commercial Fisheries Working Groups. For the onshore surveys we have been liaising with landowners in relation to surveying land and statutory consultees.


Offshore surveys

  • Geophysical and environmental surveys at the Five Estuaries site commenced in August 2021 and are expected to be completed in November 2021.

Onshore surveys

  • Habitat surveys from August through to the end of September 2021.
  • Bird surveys from September 2021 through to the end of April 2022.
  • Geophysical surveys in 2022.
  • Further habitat and species surveys commencing early 2022.
