Offshore Wind Energy Resources and the Environment
Establishing environmental parameters is an important piece of the offshore wind research agenda. This includes characterizing offshore wind resources, understanding the environmental impacts of offshore wind construction on wildlife and the marine environment, and mitigating the impact of offshore wind turbines on radar and other communication and navigation equipment. The links below will take you to resources and projects developed by the Wind Program and its partners in order to address these topics.
Wind Resource Characterization and Design Conditions
- AWS Truepower has developed a Web-based, national inventory called Met-Ocean Data Center for Offshore Renewable Energy (USMODCORE). Over the course of the project, AWS Truepower established data needs for wind energy resources and design conditions, identified existing sources of relevant data, and carried out a gaps analysis to establish long-term requirements for new data to be gathered and disseminated through national public-private collaboration initiatives.
- Indiana University is integrating wind data from remote sensing, aerial and satellite measurements, and meteorological towers to produce a high resolution wind characterization for Lake Erie. This project is also analyzing instruments and developing best practices for each measurement type.
- Savannah River National Laboratories is examining what conditions produce breaking waves and how breaking waves can impact offshore wind turbine structures in the south eastern region of the United States.
Environmental Surveys, Monitoring Tools, and Resources
- In order to promote the collaborative development of complementary models and compatible databases for offshore wildlife surveys, the Wind Program hosted a workshop focused on efforts to establish and predict marine mammal, seabird, and sea turtle abundance, density, and distributions extending from the shoreline to the edge of the Exclusive Economic Zone between Nantucket Sound, Massachusetts and Cape Hatteras, North Carolina. The Mid-Atlantic Marine Wildlife Workshop report and related appendices provide detailed information on the meeting sessions.
- As part of an international collaboration with the International Energy Agency, the Energy Department and Pacific Northwest National Laboratory developed Tethys, a database that catalogs results of environmental monitoring and research efforts on ocean energy development worldwide, including offshore wind. The database will help industry regulators and energy project developers deploy sustainable ocean energy projects in an environmentally responsible manner.
- Building on a pilot study of acoustic bat and marine radar surveys funded by the Department of the Interior, the Energy Department has provided Stantec with additional funding to expand their study of the migratory patterns of birds and bats to include proposed locations of offshore wind farms. These data will inform future siting, permitting, mitigation, and operational decisions for offshore wind development.
- The Biodiversity Research Institute is collecting the data required to inform the siting and permitting processes for offshore wind energy development in the mid-Atlantic. Currently two years into their three year effort, data on bird, sea turtle, and marine mammal abundance and movement are being collected and analyzed in scientifically sound ways, using a variety of technologies and methods, and will be presented to stakeholders and regulators in easily accessible formats that are useful for making informed decisions.
Electromagnetic Interference Research
A team led by researchers from the University of Texas conducted a baseline evaluation of electromagnetic and acoustical challenges to sea surface, subsurface, and airborne electronic systems presented by offshore wind farms.
Planning, Constructing, and Integrating Offshore Wind Energy
The Wind Program is also working to enable the nascent U.S. offshore wind industry by funding projects aimed at the development of planning, construction, and integration practices, which will ensure offshore wind energy is deployed in a cost-effective manner with minimal risk to the electrical grid. By developing a better understanding of offshore wind supply chains, available U.S. ports and vessels, and requirements for connecting offshore wind energy to existing grid infrastructure, the program can assist industry in the responsible planning and deployment of this abundant energy source.
Transmission Planning and Interconnection Studies
- ABB assessed the likely impacts of offshore wind development in the various regions of the United States from the electric utility perspective. This work included developing energy production profiles, performing an initial integration analysis, and evaluating the applicability of traditional integration study methods and potential energy collection and delivery technologies. ABB's final report suggest that the United States has sufficient offshore wind energy resources to enable the installation of at least 54 GW of offshore wind capacity—enough to power nearly 17 million homes—and that the appropriate transmission technologies already exist to connect this offshore wind energy to the grid.
- The University of Delaware is examining potential effects of wind penetration on the Mid-Atlantic electric grid and facilitating grid operations planning by identifying necessary system upgrades and grid management strategies to ensure reliable and efficient operation of the electric system.
- Case Western University is evaluating potential impacts of offshore wind on the electric grid in the Great Lakes region and determining requirements for interconnection, control systems, and the application of additional support for different transmission systems.
- Duke Energy Business Services is examining the potential effects of offshore wind development on the Duke Energy Carolinas system by determining costs of upgrading the transmission system to support large-scale offshore projects, and assessing strategies for system integration and management.
Evaluating Vessels and Ports
- Douglas-Westwood investigated the anticipated demand for various vessel types associated with offshore wind development under multiple growth scenarios, projecting installed capacity and vessel requirements out to 2030. The final report assesses vessel needs under each scenario and the United States' ability to meet those needs.
- GL Garrad Hassan America carried out a review of the current capability of U.S. ports to support offshore wind project development and assessed the challenges and opportunities related to upgrading this capability to support the targeted growth of as many as 54 gigawatts of offshore wind installed in U.S. waters by 2030. The final port assessment report includes case studies of six ports from different geographic regions and varied levels of interest and preparedness toward offshore wind, which yielded a set of best practices for U.S. ports looking to support the offshore wind market. GL Garrad Hassan has also created a publicly available port evaluation tool which allows the user to identify ports that are well-suited to specific project needs. Port operators can also use this tool to identify areas in which additional investments are required at their facility to support offshore wind installation and maintenance.
Manufacturing and Supply Chain Development
- Sandia launched an innovative project to develop offshore vertical-axis wind turbine (VAWT) rotors. This project seeks to advance large offshore VAWT rotor technology from concept to lab-scale prototype stage through four major research thrusts:
- Innovative aeroelastic rotor conceptual design
- Deep-water system design and cost analysis
- Rotor material and manufacturing strategies
- Subscale rotor prototype design and testing.
- The Navigant Consortium, as part of a multi-year project, authored the U.S. Offshore Wind Market and Economic Analysis for the program. The offshore wind market assessment report and spreadsheet of supporting data provide stakeholders with a reliable and consistent data source. Currently in its third edition, previous year's reports are still available for download, including the 2012 edition that contains significant policy and economic analyses that are not featured in the newer editions.
- The Global Wind Network (GLWN) assessed the key factors that determine wind energy component manufacturing costs and pricing on a global basis in order to provide a better understanding of the factors that will help enhance the competitiveness of U.S. manufacturers, and reduce installed system costs. Key findings from the report indicate that globally, the United States has the most efficient manufacturing process for towers, blades, and generators, and that U.S. manufacturers have the capability to supply key components of next-generation 3-megawatt wind turbines.
- Navigant surveyed uncertainties around the United States' offshore wind manufacturing and supply chain capabilities. The final report projects potential component-level supply chain needs under three demand scenarios, and identifies key supply chain challenges and opportunities facing both the future U.S. offshore wind market and current suppliers of the nation's land-based wind market.
- The Clean Energy States Alliance (CESA), in conjunction with Douglas-Westwood and the U.S. Offshore Wind Collaborative, analyzed offshore wind supply chain development opportunities in 24 coastal states. The state profiles produced by the CESA-led team provide detailed information on policies, tax credits, and other incentives for offshore wind businesses.
Optimizing Infrastructure and Operations
- GL Garrad Hassan America has identified and quantifyied key areas of offshore wind project installation and operations where opportunities exist to reduce the cost of energy produced by offshore wind plants. The project developed both a report and a publicly-available Excel-based Installation and O&M Levelized Cost of Energy (LCoE) Analysis Tool that enables project developers, owners, and managers to evaluate and compare how various installation and maintenance strategies and technical approaches impact cost of energy.
- DOE's National Renewable Energy Laboratory (NREL) conducted an assessment of optimized installation, operation, and maintenance strategies and technologies for offshore wind projects in U.S. waters to evaluate their relative costs and benefits. The report combines NREL's offshore wind cost modeling capabilities and those of the Energy Research Centre of the Netherlands, along with the operating experience of an expert industry panel.
