U.S. Department of the Interior data details planned and existing offshore wind export cable routes. It includes multiple proposed layout options for project planning and permitting review. The dataset is updated with new publicly available information, with a last recorded update in April 2026.

Use Cases

• Analyze proposed cable route locations against marine protected areas or shipping lanes using geospatial features.
• Compare multiple proposed layout options for a single project to assess planning flexibility.
• Track changes between proposed and installed cable paths over time using temporal updates.
• Identify the maximum proposed build-out within a project's design envelope from the attribute data.

Strengths

• Includes both proposed and installed cable data for comparative analysis.
• Provides multiple proposed layout options for some projects.
• Updated as new public information is released, with a recent update in 2026.

Limitations

• Proposed cable locations are subject to change prior to installation.
• The total number and final placement of cables may differ from the presented data.
• Specific sample size, row count, and column details are unknown.
