Offshore Wind – Export Cable Corridors (Proposed)

Tags  BOEM, Bureau of Ocean Energy Management, Wind, Offshore, Facilities, Infrastructure, Renewable Energy, Export Cable Corridor

Summary

Export Cables are the electrical cables that will carry electricity from the power generators (wind turbines) to a power substation. These polygons represent the potential area (easement) in which proposed locations of the export cable portions of a wind farm may be installed and are meant to show the area that the developer intends to investigate for the final location of one or more export cables that the developers of the wind farms intend to build.

Description

These data represent the proposed area the developer intends to investigate for the location of one or more export cables, the electrical cables that will carry electricity from the wind turbines to a power substation. Cable study locations are shown as the most favorable option (1) to alternate options (2,3,4,5) from the perspective of the wind farm developer. Since proposed project design, review, and permitting is an iterative process, the final design and buildout of the features may vary from what is presented here. Users should also be aware that developers often show more than one alternative, and all of these will not necessarily represent the final permitted design but are part of many options to be reviewed. These data will be updated as new publicly available information is released. Data are provided by the lessee for project planning review and permitting uses.
