Offshore Wind - Export Cables (Proposed or Installed)

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

Summary

These lines which represent the installed or proposed locations of the "Export Cable" portions of a wind farm show the current plans that the developers of the wind farms intend to build. Note that until installation occurs, these locations can change.

Description

These data contain both proposed and installed export cables. The proposed cables show the developer’s current plans, but until installation occurs, these locations are subject to change. These preliminary data are being provided to help inform stakeholders of the intended location so they can provide feedback regarding the potential location of these cables. In most cases, the cables shown are the maximum proposed build out within the individual design envelope of the project. In some cases, more than one proposed layout is provided. If no specific configuration option is shown in the attributes, then all the locations are considered the preferred option. Regardless of which option is ultimately permitted, the placement and total number of cables built may vary from what is presented here. 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.
