Offshore Wind Farm Cable Interconnection Locations

Geospatial data details the locations of proposed and installed cable interconnections for offshore wind energy facilities. The dataset is maintained by the U.S. Department of the Interior and was last updated in April 2026. It is provided by project lessees for planning review and permitting purposes.

Use Cases

• Map proposed interconnection points using the provided geospatial coordinates and project polygons.
• Analyze the spatial distribution and density of planned buildouts within project design envelopes.
• Compare multiple proposed configuration options for a single wind farm project where available.
• Track updates to interconnection placement and count as new public information is released.

Strengths

• Data includes both proposed and installed facilities, showing project evolution.
• Locations represent the maximum proposed buildout within individual project design envelopes.
• Multiple proposed configuration options are provided for some projects.

Limitations

• The final placement and total number of interconnections are subject to change from what is shown.
• Specific data volume metrics like row count or file size are not provided.
• The dataset may have geographic bias limited to U.S. offshore wind projects under Department of the Interior jurisdiction.
