About East Anglia ONE

The proposed East Anglia ONE Offshore Windfarm development is located in the south of the zone and covers an area of approximately 300km2.  The East Anglia ONE project is likely to include:

  • Offshore wind turbines and foundations (up to 240 wind turbines to provide an installed capacity of 1,200MW).
  • Up to three offshore collector stations and up to two offshore converter stations and their foundations to collect the electricity from the turbines and transform it to a form suitable for transfer to shore.
  • Up to four seabed export cables, each around 73km in length, to transfer the electricity to shore.
  • A landfall site with onshore transition pits to connect the offshore and onshore cables.
  • Up to four onshore underground cables, each of around 37km in length, to transfer the electricity from landfall to an onshore converter station.
  • Up to eight cable ducts for two future East Anglia projects to connect into Bramford Substation to limit the impact of future construction operations, as cables could be pulled through the pre-laid ducts.
  • An onshore converter station adjacent to the existing substation at Bramford, Suffolk, to connect the offshore windfarm to the National Grid.

The consent application for East Anglia ONE was submitted to the Planning Inspectorate in November 2012. This was a combined application for both the offshore windfarm and the electricity transmission works.  It was accepted for examination on 14th December 2012 and consented in June 2014.
