U.S. Offshore Wind Lease Boundary Polygons

Outline polygons for active offshore wind leases managed by the Bureau of Ocean Energy Management. The dataset covers commercial, research, and right-of-way lease areas within U.S. Outer Continental Shelf waters. It was last updated by the Department of the Interior in April 2026.

Use Cases

• Analyze spatial overlap between lease polygons and marine habitats using geographic coordinates.
• Map the distribution of commercial versus research lease areas using lease type attributes.
• Calculate total leased ocean area by dissolving block polygons by lease number.
• Assess provisional lease status for auction tracking using status or date fields.

Strengths

• Includes all active offshore wind leasing areas within U.S. Outer Continental Shelf waters.
• Data is provided in multiple geospatial formats including GeoJSON, KML, and GPKG.
• Managed by the authoritative Bureau of Ocean Energy Management (BOEM).

Limitations

• Specific row counts, sample sizes, and temporal coverage for lease history are not provided.
• Easement sections are noted as not dissolved into the main lease polygons, requiring separate handling.
