Renewable Energy

Offshore wind in the Mid-Atlantic holds more than 60,000 Megawatts of potential energy — that’s 10% of total U.S. offshore potential. This huge resource could help meet the growing electricity demand in the region, while reducing carbon emissions.

BOEM Wind Planning Areas

This data set represents the most recent changes for the Wind Development Planning Areas in the Atlantic. Wind Planning Areas in this dataset represent up to seven different types of announcements within the US Federal Register (e.g. Call Area, Wind Energy Area, Request for Interest, Proposed Sale Notice Area) that can be used to show the current status of an area that is being considered for Wind Power Development.

Coastal Energy Facilities

This data product depicts the locations of facilities that generate electricity. Only facilities adjacent to the coast and Great Lakes are identified. Contained within the database are records that define the fuel source and other characteristics of the facility that may benefit ocean planners. In some cases, the presence of a facility may indicate that certain power transmission infrastructure exists nearby. Absence of a facility or lack of sufficient capacity at a facility in a given area may also be an important characteristic in future energy planning activities.

BOEM Active Renewable Energy Lease Areas

These are blocks which have been leased by a company with the intent to build a wind energy facility. No projects are in the development stage at this time; permits may be issued for development provided further site assessment for each leased area.

Department of Defense Offshore Wind Mission Compatibility Assessments

This data set shows the results of a Department of Defense assessment of the compatibility of offshore wind development with military assets and activities. These data should not be used to infer compatibility or conflict between military assets or activities with any use other than offshore wind. The data set contains 4 categories of OCS lease blocks: No Restrictions - No significant conflicts were identified. Site Specific Stipulations - Potential conflicts exist and may require site specific mitigation measures. Recommended Wind Exclusion - Significant conflicts were identified. Not Assessed - DoD only assesses specific lease blocks as requested by BOEM and the appropriate coastal state task force.

Offshore Wind Energy Technology Zones

Coastal bathymetric depth, measured in meters at depth values of: -30, -60, -900 Shallow Zone (0-30m): Technology has been demonstrated on a commercial scale at these depths. Foundation types include monopile, gravity base and suction buckets designs. Transition Zone (30-60m): Technology has not been demonstrated on a commercial scale at these depths but several small scale projects have been successfully installed and commissioned at these depths Foundation types include tripod, jacket and tripile designs. Deepwater Zone (60 - 900m): Technology has not been demonstrated on a commercial scale at these depths but several pilot projects have been successfully demonstrated. Foundation types include spar, semi-submersible and tension leg platform designs.

Virginia Research Lease Areas

Offshore wind has the potential to provide the largest, scalable renewable resource for Virginia if it can be achieved at reasonable cost to customers. To help determine how this can be accomplished, Dominion is involved in the Virginia Offshore Wind Technology Advancement Project (VOWTAP), a research and development project supporting offshore wind generation. These research lease areas show where this project is taking place.

Wind Speed

Annual average wind speeds are closely related to the available energy at a particular location. In these data, wind speeds are categorized by their value at a height of 90 meters above the surface. The data were created by the National Renewable Energy Laboratory (NREL) and AWS Truepower. Wind speed data for all of the MARCO states was created as part of onshore wind mapping projects. Speed data was extrapolated to 50 nautical miles offshore by NREL. The 90 m wind speed was calculated by a linear interpolation between 70 m and 100 m wind speeds.

This layer represents an estimate of offshore annual average wind speeds and is based primarily on data extrapolated from onshore wind data, which is a source of uncertainty in the dataset. For more information visit nrel.gov and search for Technical Report TP-500-45889.
