2 THE PROPOSED EAST ANGLIA THREE OFFSHORE WINDFARM 6.


The East Anglia THREE site is located in the southern North Sea approximately 69 kilometres (km) from its nearest point to the port of Lowestoft on the East Anglian coast. The proposed project would consist of between 100 and 172 wind turbines, with a total installed capacity of up to 1,200 megawatts (MW). The wind turbines would have a maximum tip height of 247 metres (m) above lowest astronomical tide. Within the windfarm there would also be several collector and converter stations as well as meteorological masts and potentially an accommodation platform.

The proposed project would be connected to the National Grid via sub-sea cables going from the site to the landfall at Bawdsey in Suffolk. From the landfall the cables would be buried along a 37km onshore cable route to a new converter station, built next to the existing National Grid sub-station at Bramford. Onshore works would start in 2020. Offshore construction of the project would begin in 2019 and would continue for up to two and a half years.

The location of the onshore cable route for East Anglia THREE was determined during the development of the East Anglia ONE OffshoreWindfarm. The onshore cable route for the East Anglia ONE project was designed to be sufficient to place cables for two future projects. East Anglia THREE would therefore follow the same onshore cable route as the proposed East Anglia ONE project. From the outset (during the development of the East Anglia ONE project) careful routeing of the onshore electrical transmission works set out to avoid key areas of sensitivity wherever possible.
