Proposed Export Cable Corridors for Offshore Wind Farms

Proposed geospatial areas for offshore wind farm export cable routes, representing developer-favored and alternative options. The dataset is provided by project lessees for planning and permitting review. Data is updated as new public information becomes available, with a last recorded update in April 2026.

Use Cases

• Analyze spatial relationships between proposed cable corridors and other marine features using polygon geometry.
• Compare developer preference rankings (e.g., option 1 vs. options 2-5) for different cable route alternatives.
• Assess project evolution by tracking updates to proposed corridor geometries over time.

Strengths

• Data includes multiple proposed alternatives (e.g., options 1 through 5) for comparative analysis.
• Updates are planned as new public information is released, indicating a maintained resource.

Limitations

• The final built infrastructure may differ from all proposed alternatives shown.
• Specific quantitative metrics like total area or cable length are not provided in the description.
