Maryland Offshore Wind Commercial Lease Map

What's New?

On September 5, 2024, the Department of the Interior announced the approval of the Maryland Offshore Wind Project – the nation’s tenth commercial-scale offshore wind energy project. The project could generate over 2 gigawatts of clean, renewable energy for the Delmarva Peninsula and power over 718,000 homes. Additionally, the development and construction phases of the project could support almost 2,680 jobs annually over seven years. The lease area is approximately 8.7 nautical miles offshore Maryland and approximately 9 nautical miles from Sussex County, Delaware, at its closest points to shore.

The Maryland Offshore Wind Project consists of three planned phases, which include the proposed installation of up to 114 wind turbine generators, up to four offshore substation platforms, one meteorological tower, and up to four offshore export cable corridors. Two phases, known as MarWin and Momentum Wind, already have offshore renewable energy certificates from the State of Maryland.

Background 

On August 19, 2014, BOEM held a competitive lease sale offshore Maryland. US Wind Inc. was identified as the winner of Lease Area OCS-A 0490 (46,970 acres) located 10 nautical miles offshore Ocean City, Maryland in federal waters. Maryland Offshore Wind is in the environmental review phase within BOEM’s authorization process. This project is covered under FAST-41 and permitting progress can be found on the Federal Permitting Improvement Steering Council (FPISC) dashboard.

For more information on this lease area, including Intergovernmental Renewable Energy Task Force meetings and lease history please visit the Planning and Lease Sale page. For more information on public meetings, please visit the Environmental Review tab. For up-to-date leasing information, including the original lease and any lease amendments that may have occurred since the initial lease execution, visit the Lease and Grants page.

Site Assessment Plan

On March 22, 2018, BOEM approved the Site Assessment Plan (SAP) for Lease OCS-A 0490 submitted by US Wind, Inc. The SAP approval allows for the installation of and data collection from a meteorological tower, a seabed mounted acoustic Doppler current profiler (ADCP) sensor and a conductivity, temperature, and depth (CTD) sensor. For additional information, please find the approved SAP below:    

On October 22, 2020, US Wind, Inc. submitted a second SAP to BOEM for meteorological evaluations and site assessment. The plan details the methods and procedures U.S. Wind, Inc. will use to collect and analyze meteorological and oceanographic data and information on the conditions of the marine environment within its commercial lease. On May 5, 2021, BOEM approved the SAP for Lease OCS-A 0490, allowing for the installation of a meteorological buoy. For additional information, please find the approved SAP below:

US Wind Inc. submitted its Construction and Operations Plan (COP) on August 11, 2020. Updated COP versions were submitted on November 23, 2021; March 3, 2022; May 27, 2022; November 30, 2022; and July 28, 2023; February 26, 2024; May 10, 2024; June 25, 2024; and July 1, 2024. BOEM will review the COP and approve, disapprove, or approve with modifications the proposed activities. 
 
US Wind Inc. intends to develop, build, operate, and own an up to 2,200 MW commercial offshore wind energy facility, also known as the Maryland Offshore Wind project. The project is located within federal waters on the Outer Continental Shelf (OCS), specifically in BOEM Renewable Energy Lease Area OCS-A 0490, approximately 10 nautical miles offshore Ocean City, Maryland, and approximately 9 nautical miles offshore Sussex County, Delaware.

The project includes MarWin, a wind farm of approximately 300 MW for which US Wind was awarded offshore wind renewable energy credits (ORECs) in 2017 by the State of Maryland; Momentum Wind, consisting of approximately 808 MW for which the State of Maryland awarded additional ORECs in 2021; and build out of the remainder of the Lease Area to fulfill ongoing, government-sponsored demands for offshore wind energy.

Notice of Intent to Prepare a Draft Environmental Impact Statement (NOI EIS)

On June 6, 2022, BOEM announced the intent to prepare a draft Environmental Impact Statement for the Maryland Offshore Wind project.  The Notice of Intent (NOI) was published in the Federal Register on June 8, 2022. The following documents are available for your viewing:  

The Notice of Intent initiated a 30-day public comment period that ended on July 8, 2022.

Draft Environmental Impact Statement (Draft EIS)

On September 29, 2023, BOEM announced the availability of the draft EIS for the proposed Maryland Offshore Wind project. The Notice of Availability and draft EIS can be accessed using the links below.  

Two in-person meetings and two virtual meetings were held during the 45-day draft EIS comment period. In-person meetings followed an informal open house format where attendees were given the opportunity to ask questions one-on-one of BOEM subject matter experts and to submit oral and written comments for the record. During each virtual meeting, BOEM provided an overview presentation, after which members of the public made formal oral public statements for the record.

Map of Visual Simulations from Key Observation Points (KOPs)

Visual Impact Assessment

The visual impact assessment includes photo simulations of the proposed Maryland Offshore Wind Project from numerous Key Observation Points (KOPs) and provides a detailed analysis of the potential visibility of the proposed Project and differences in landscape visual quality with and without the Project in place. A video simulation was also produced viewing from KOP 6: 84th Street Beach.

In addition, photo-simulations were produced for Alternative D – No Surface Occupancy to Reduce Visual Impacts Alternative.

BOEM recommends viewing the simulations in accordance with the instructions below for viewing printed photos or on-screen viewing to fully understand the overall horizontal and vertical size and scale of the project represented in the photo simulations. Each simulation contains instructions for viewing with a scaling bar.  Once the scale is set, it is likely that the simulation will be larger than the monitor’s screen.

Photo simulations are presented in two formats: panoramic photo format, which approximates the human-field-of-view, and single frame photo format taken with a 50 mm lens on a 35 mm full-frame camera, which represents the “normal” camera lens field-of-view. Each format set has a purpose.

The panoramic photo format approximates the human field-of-view and illustrates the horizontal breadth a person may see when standing at the location and looking in the direction the photo was taken. This photo informs the viewer how much of horizontal span of view would be occupied by the project without moving the head from side to side.  However, the panoramic photo simulation does not properly illustrate the vertical size and scale of the wind turbines and other offshore facilities associated with the wind energy development.

The single frame photo taken with a 50 mm lens on a 35 mm full-frame camera approximates the size and scale of the project’s offshore wind turbines and other associated offshore facilities at the photo-point location.  However, the horizontal field-of-view in the single frame is considerably less than the human field-of-view.

Photo simulations of the proposed Maryland Wind Offshore Wind Project from all KOPs (see Map Figure 1-KOPs and KOPs with simulations) may be viewed or downloaded in the following:

*As part of the COP review, a time-lapse video was produced that depicts daytime and nighttime conditions under a variety of lighting conditions (including nighttime), cloud cover, and weather scenarios.  As discussed in Appendix II-J (Visual Impact Assessment) of the COP, based on past flight data and the use of Aircraft Detection Lighting Systems (ADLS), the aviation obstruction lights associated with the project would only be activated for a total of approximately 5 hours and 46 minutes over a one-year period, or 1% of the time.  The simulation is at the proper perspective when viewed at a distance of approximately twice the image height. 

Cumulative Historic Resources Visual Effects Analysis (CHRVEA) 

The BOEM Cumulative Historic Resources Visual Effects Analysis (CHRVEA) provides an assessment of the Project’s contribution to cumulative visual effects on historic properties when combined with other reasonably foreseeable offshore wind energy development activities in the area.
