Offshore Wind Development - Site Suitability Prototype

Access the Offshore Wind Development Site Suitability Prototype

Please note that we no longer support the Esri license required to run some functionality within this tool. In addition, the data within this tool may be outdated, and there are no plans to perform updates. Please contact the team if you are interested in learning more about the application.

The Offshore Wind Development – Site Suitability Prototype was developed in partnership with Esri as part of a technology demonstration project. Currently, the prototype provides a simple Web-based interface that allows users to interact with Marine Cadastre data to perform analysis for offshore wind development siting. The coverage area for this prototype is the eastern seaboard from Maine to Florida.

Users can perform the following analysis:

  • Filter lease blocks based on user-defined criteriaWind Suitability Tool, Northeast
  • Generate dashboard-style reporting
  • Perform simple viewshed analysis
  • Export blocks that meet user-defined criteria

The purpose of the project is twofold:

  1. To demonstrate how Web-based GIS can support offshore renewable energy planning
  2. To develop requirements for future iterations of this tool or other
    decision-support toolsWind Suitability Tool, Northeast

The future of this tool will be based largely on customer response. Please provide feedback  as to how you might use the tool, where in the planning process a tool like this would fit, and what additional data and functionality would help with decision making.


  1. The entire application was developed for prototype purposes only.
  2. The tool provides a basic first-pass viewshed calculation based on the height of the proposed wind turbine. This functionality gives the planner the ability to see if there is a possibility of seeing a wind turbine from a specific point on the coast.
  3. It is especially important to note that the viewshed analysis tool does not take into consideration weather-related variables and other visual impediments. The viewshed scenarios generated from the tool are based on optimal viewing conditions.
