2 THE PROPOSAL 19.


It is anticipated that East Anglia THREE would consist of the following infrastructure:


Offshore wind turbines and associated foundations (anticipated to be up to 240 wind turbines, each having a rated capacity of between 5MW and 10MW, with an installed capacity of up to 1,200 MW, which could provide enough cleaner, greener energy for over 770,000 homes1);


Up to three offshore collector stations and up to two offshore converter station platforms;


Subsea interarray cables between the wind turbines and converter station and collector station platforms;


Up to four subsea export cables to transmit electricity from the offshore platforms to shore;


Scour protection around foundations and on inter-array and export cables as required;


Landfall at Bawdsey with onshore transition pits to join the offshore and onshore cables;


Onshore underground export cables (up to four), associated jointing pits, ducting (if applicable)2, protection and associated equipment where required; and


An onshore converter station at Bramford, Suffolk. 20.


The draft Development Consent Order (DCO) for the East Anglia ONE Offshore Windfarm also includes provision for the installation of onshore cable ducts for the connection of two further projects from the East Anglia Zone to the grid at Bramford. This installation option, if consented, would reduce disruption to local communities. Final construction methodologies will, however be subject to the terms of the East Anglia ONE consent and technical feasibility. For this reason, the DCO application for East Anglia THREE Offshore Windfarm will assess both the


1 Calculated using a 31.96% capacity factor (the UK average for offshore wind as supplied by DECC Digest of United Kingdom Energy Statistics) and an annual household consumption of 4,266 kilowatt hours, correct as of


July 2013. 2 Further detail on the requirement for ducting is provided in the East Anglia THREE Scoping Report, and East Anglia THREE Summary of Environmental Considerations – Onshore.
