4.4.3 East Anglia THREE Offshore Cable Corridor 23.
EAOW signed a grid connection agreement with National Grid in November 2010, which confirmed Bramford, Suffolk, as the connection point for 3.6 GW of capacity, allowing the connection of up to three 1,200MW projects from within the Zone. The process of onshore cable route and offshore cable corridor selection for the proposed East Anglia ONE project has therefore included consideration of the proposed East Anglia THREE, and the proposed East Anglia FOUR, projects.
24.
The East Anglia THREE offshore cable corridor comprises two main parts. The first part is essentially the East Anglia ONE offshore cable corridor. This was identified through an initial broad area of search, with environmental and technical constraints then analysed to refine this in combination with consultation with relevant stakeholders.
25.
The second part, which comprises the connection from the East Anglia THREE site to the East Anglia ONE offshore cable corridor, was defined through consideration of environmental and technical constraints. This section of the offshore cable corridor may be refined (reduced in extent) prior to submission of the DCO application following consultation.
26. The offshore cable corridor is shown in Figure 1.1.
4.4.4 Landfall 27. During development of East Anglia ONE a constraints mapping and engineering feasibility study was conducted to identify the most appropriate location for the East Anglia ONE offshore export cables, and those from two further projects within the Zone, to make landfall. The proposed East Anglia THREE project would therefore utilise the same landfall location.
28. Mapping of constraints at or near the shoreline identified three potential landfall locations based on the following key parameters:
29.
Avoiding areas with significant infrastructure or land use e.g. housing and coastal defences;
Avoiding areas with European, national and local ecological designations; and Avoiding landscape and cultural heritage designations.
Possible landfall locations identified were: Bawdsey Cliffs (between the Martello Tower and Bawdsey Manor); between Felixstowe and Felixstowe Ferry; and south of Harwich near Little Oakley. Other potential options such as laying the export cables
