The Mid-Atlantic has a gently sloping continental shelf and strong offshore winds, making offshore wind energy a focus of policy, research, and investment for the region. The Mid-Atlantic states are increasingly looking to offshore wind as an energy source that can help them meet their renewable portfolio standards and goals.
While offshore wind is a target industry for energy production in the region, it is imperative that offshore wind development proceed with full consideration of any potential effects on marine life as well as other ocean resources and uses. To help coastal managers and decision makers build understanding of the potential interactions between offshore wind development and other ocean uses and resources MARCO’s Mid-Atlantic Ocean Data Portal houses and displays thousands of data layers.
Current federal Bureau of Ocean Energy Management (BOEM) offshore wind development lease areas are depicted
in a series of Portal maps and can be overlayed with habitat, fisheries, and other
ocean use data layers. Scroll below for a tour of offshore energy lease areas throughout the Mid-Atlantic.
The Empire Wind project, a roughly 80,000-acre triangular area located roughly 20 miles outside of New York Harbor, is expected to produce over 800 MW of energy. It is leased by Equinor Wind US.
New York State plans to generate electricity from a cluster of offshore wind lease areas:
The Sunrise Wind project is currently proposed for portions of the Bay State Wind and Deepwater Wind New England lease areas (seen in green and grey). The project is a joint venture of Ørsted and Eversource Energy. It would be located roughly 30 miles from Montauk, Long Island, and is expected to produce 880 MW. Projects delivering energy to other states are also potentially being proposed in these leases areas.
The South Fork Wind Farm would be located in the Atlantic Ocean 35 miles east of Montauk Point and is projected to produce 130 MW. The state will draw from one portion (delineated in the orange and brown squares) of a larger area (seen in red) leased by Deepwater Wind New England.
BOEM is also evaluating the suitability of additional areas within the New York Bight, as depicted in the BOEM Wind Planning Areas layer.
There are currently two conjoined lease areas roughly 10 miles off the coast of Atlantic City, New Jersey:
- To the north (in red) is the 183,000-acre Atlantic Shores project area, leased jointly by EDF Renewables and Shell.
- To the south (in dark green) is the 160,000-acre Ocean Wind project area, leased by Ørsted. The area is expected to generate 1,100 MW of power for New Jersey.
Delaware & Maryland
There are currently three lease areas located off the coasts of Delaware and Maryland.
- To the north (in brown) is the 70,000-acre GSOE I area. Directly adjoining it to the south is the 26,000-acre Skipjack Offshore Energy area (seen in light green). Ørsted is the lease holder for both projects.
- Approximately seven miles south, and 10 miles off the coasts of Delaware and Maryland, is an 80,000-acre area (seen in yellow) leased by U.S. Wind.
The first offshore wind turbines in U.S. federal waters are now producing power off the coast of Virginia. Installation was completed on two turbines in the summer of 2020 and they became fully operational by October.
The Coastal Virginia Offshore Wind (CVOW) pilot project is designed to demonstrate a grid-connected, 12-megawatt offshore wind test facility on the Outer Continental Shelf about 27 miles off the coast of Virginia Beach. The data obtained and lessons learned from this project will be made publicly available and inform the future production of renewable energy within the adjacent commercial lease area, where construction is expected to begin in 2024. The research site is leased by the Commonwealth of Virginia’s Department of Mines, Minerals and Energy. Dominion Energy was designated as the lease operator and contracted with Ørsted to construct the turbines and L.E. Myers Company to perform onshore electrical design and construction.
Approximately 115,000 acres of offshore has been leased for offshore wind development, including one aliquot (shown as dark square) that was designated for the development of the test turbines (sites marked as turbine icons). A submarine power cable connecting to this area is seen in blue. The full Virginia lease area, controlled by Dominion Energy and Ørsted, is anticipated to produce 2,500 MW of electricity.
Ecological and Economic Considerations
Offshore wind energy is a growing industry in the Mid-Atlantic, and it is important that impacts to the ocean’s ecological and economic resources are carefully considered during the planning and management of new and existing projects.
Portal can be used to identify potential interactions between the
fisheries industry with offshore wind lease areas. The site contains
over 1,000 interactive maps showing commercial fishing activities, with
layers based on federal vessel trip reports (VTR), vessel monitoring
system (VMS) data, automatic identification system (AIS) transit counts
The map above shows AIS data for federally permitted fishing vessels of all types in 2017 and the BOEM lease areas.
The map now transitions to display an overlay of the BOEM lease areas and one type of fishing activity -- in this case, VMS data for surfclam/ocean quahog fishing in 2015-16.
Below are some fisheries-specific informational resources for the Mid-Atlantic region.
- The Responsible Offshore Development Alliance (RODA) is a coalition of fisheries industry members that was created to foster collaboration with regulatory agencies in order to minimize impacts to fisheries during offshore development activities.
- The Responsible Offshore Science Alliance (ROSA) was initiated by RODA and is specifically focused on advancing research and monitoring efforts associated with fisheries and offshore wind interactions.
- The Mid-Atlantic Fishery Management Council (MAFMC) offshore wind resource page.

The Mid-Atlantic coast provides habitats for a number of migratory and non-migratory birds, marine mammals, sea turtles, corals, and more, including some that are considered threatened or endangered. The Portal houses over 4,000 data layers depicting the abundance and species richness for many marine life groups and individual species.
These data layers can be activated in combination with those showing offshore wind areas, to help users analyze their compatibility. The map above shows the abundance of marine birds with high collision sensitivity and BOEM's Active Renewable Energy Lease Areas.
Regulatory Framework/Policy Considerations
All of the proposed offshore wind leases In the Mid-Atlantic are located on the Outer Continental Shelf (OCS), which encompasses all Federal submerged land, subsoil, and seabed from 3 to 200 nautical miles offshore. The Energy Policy Act of 2005 placed oversight responsibility on BOEM for all renewable energy projects within the OCS. Thus, BOEM is responsible for issuing leases, easements and rights of way for offshore wind projects.
Many states conduct Federal Consistency reviews to ensure that federal actions are consistent with state coastal management policies. States participating in the federal consistency provision of the Coastal Zone Management Act may have the authority to review offshore wind development activities to ensure federal actions are consistent with that state’s coastal management policies.
Federal consistency is the principal tool that allows states to influence OCS activities, as many may not directly require a state permit or approval for implementation (with the exception of associated facilities in or on state waters or lands). Included within the consistency review is a mandatory public comment period, in which states are required to provide for public participation.
States are provided
an opportunity to communicate with BOEM about offshore wind projects through
the Intergovernmental Task Force, which was created by BOEM in each state that
has expressed interest in offshore wind development. Some states also offer state-led
stakeholder meetings in addition to the BOEM Intergovernmental Task Force
meetings. Meeting information for each MARCO state is listed below.
