Proposed Offshore Wind Farm Export Cable Corridors

Proposed export cable corridors represent up to five alternative routing options for electricity transmission from offshore wind turbines to onshore substations. The Department of the Interior provides this data for project planning, review, and permitting, with updates released as new public information becomes available. Data reflects developer-proposed study areas, with final permitted designs subject to change.

Use Cases

• Analyze spatial overlap between proposed cable corridors and marine habitats using polygon geometry.
• Compare developer preference rankings (e.g., option 1 vs. alternatives 2-5) for route selection modeling.
• Assess cable corridor density and planning zones for offshore wind lease areas.
• Integrate corridor polygons with bathymetry data to evaluate seabed installation feasibility.

Strengths

• Data includes multiple proposed alternative corridors (options 1-5) per project for comparative analysis.
• Maintained by the Department of the Interior with updates as new public information is released.

Limitations

• Data represents proposed, not final, designs; actual built infrastructure may differ significantly.
• Specific row counts, temporal coverage, and geographic scope are not documented in the provided metadata.
