The East Anglia Zone is being developed as a number of individual windfarms. East Anglia ONE was the first project to be proposed within the East Anglia Zone, the Development Consent Order application for which was submitted to the Planning Inspectorate for examination in November 2012. The East Anglia ONE project is situated 43 km from the coast of Suffolk, covers an area of approximately 306km2 and will have a maximum installed capacity of 1,200MW.
13.
East Anglia THREE is one of two projects in the second phase of development proposed within the East Anglia Zone. The windfarm covers an area of approximately 370km2 and is situated 79km from the coast of Suffolk (from the midpoint of the site to the port at Lowestoft).
14. Another project named East Anglia FOUR will be developed by East Anglia FOUR Limited in parallel with East Anglia THREE, also as part of this second phase of development. This project will be subject to separate statutory consents and approvals and accordingly, separate documentation will be produced and submitted for East Anglia FOUR. A further area, which was provisionally named East Anglia TWO, has also been identified as a potential area for future development; however at this stage it is not being actively developed. East Anglia TWO will be developed as a separate project in future phases within the East Anglia Zone at a later date.
15.
The location for East Anglia THREE was decided following a robust screening exercise to establish areas of the East Anglia Zone with the lowest environmental, technical and consenting risk.
16. When deciding the location of the offshore windfarm site, key issues considered included military and civil aviation radar locations, shipping patterns, helicopter flight paths, oil and gas infrastructure, nature conservation designations and commercial fishing activity. In addition, key technical considerations included water depth and sea bed conditions and grid connection availability.
17.
EAOW has a “Generator Self-Build” Grid Connection Agreement with National Grid Electricity Transmission (NGET) for the connection of 7,200 MW of offshore wind generation to the National Grid Electricity Transmission System in East Anglia. This includes the connection of East Anglia ONE, East Anglia THREE and East Anglia FOUR to the NGET substation at Bramford, Suffolk.
18.
In order to connect the windfarm array to the existing NGET substation at Bramford, transmission infrastructure comprising offshore platforms to support up to three offshore collector stations and two offshore converter stations (within the East Anglia THREE windfarm area), offshore subsea and onshore underground cabling and
