Offshore wind power is the use of wind farms constructed in bodies of water, usually in the ocean on the continental shelf, to harvest wind energy to generate electricity. Higher wind speeds are available offshore compared to on land, so offshore wind power’s electricity generation is higher per amount of capacity installed and NIMBY opposition to construction is usually much weaker. Offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas, using traditional fixed-bottom wind turbine technologies, as well as deeper-water areas utilizing floating wind turbines.


What Ails Offshore Wind: Supply Chains, Ships and Interest Rates

Government officials and energy developers misjudged the difficulty of building huge clean energy projects in the United States, which has built very few of them. A few years ago, interest in offshore wind energy was so strong that developers proposed spending tens of billions of dollars to plunk hundreds of turbines the size of skyscrapers in the Atlantic Ocean from Maine to Virginia. But several of those projects have recently hit the skids after executives miscalculated the impact that the pandemic and rising interest rates would have on supply chains.

Developing Offshore Wind in US Waters Part 1: The Planning and Regulatory Framework

The deployment of offshore wind energy facilities in US waters has tremendous potential to help the country deliver on its climate change commitments and clean energy goals. It is also a reality beginning to take shape with the first commercial-scale facilities beginning construction in 2023 in the Northeast US. In Part 1 of our webinar series on ocean wind energy in US waters, we will explore the historical and policy background and framing behind the US wind energy transition, including an introduction to the planning and regulation processes and the players involved. This webinar will set the groundwork for future discussions exploring offshore wind energy, its future in US waters, and its compatibility and interactions with marine protected areas and other ocean uses.

DOE Launches Funding Opportunity to Improve Wind Turbine Composite Materials 

DOE announced $30 million in funding to advance composite materials and additive manufacturing for large wind turbines, including for offshore wind energy systems. This funding opportunity seeks to improve the manufacturability and performance of composite materials—materials made up of multiple constituents, such as polymers and fibers. Projects funded through this initiative will help address the priorities established in DOE’s Offshore Wind Supply Chain Road Map and Floating Offshore Wind Shot™, as well as the Biden administration’s goals to deploy 30 gigawatts of offshore wind energy by 2030 and achieve a net-zero carbon economy by 2050. 

Floating Offshore Wind Shot

The Floating Offshore Wind Shot is an initiative to help usher in a clean energy future by driving U.S. leadership in floating offshore wind design, development, and manufacturing.

It is part of the U.S. Department of Energy’s Energy Earthshots Initiative to tackle key remaining technical challenges to reaching U.S. climate goals while creating jobs and economic opportunities for U.S. communities.

Floating offshore wind is key to transitioning dense population centers to clean energy, and would also mean thousands of jobs in wind manufacturing, installation, and operations.

The Floating Offshore Wind Energy Shot seeks to reduce the cost of floating offshore wind energy by at least 70%, to $45 per megawatt-hour by 2035 for deep sites far from shore.

About two-thirds of U.S. offshore wind energy potential exists over waters too deep for today’s fixed-bottom wind turbine foundations secured directly to the sea floor, and instead require floating platforms. These structures will be among the largest humankind has ever constructed. Achieving the Floating Offshore Wind Shot goals will require an all-out effort to develop a robust domestic supply chain, reduce technology costs, and plan and build out needed transmission.

BOEM Identifies First Two Offshore Wind Areas in the Gulf of Mexico

On Wednesday, the Bureau of Ocean Energy Management announced that it has identified two wind energy areas (WEAs) on the Gulf Outer Continental Shelf, both within the giant 30 million acre call area announced in November. 

The first draft WEA is located about 24 nautical miles off the coast of Galveston. The area for review totals nearly 550,000 acres and has the potential to power 2.3 million homes with clean wind energy. A portion has been removed from the center of the region to account for shrimp-fishing interests. 

The second draft WEA is located about 56 nm off the coast of Lake Charles, Louisiana. The area for review totals 190,000 acres and has the potential to power 800,000 homes

From Policy To Power: Federal Actions to Deliver on America’s Offshore Wind Potential

Offshore wind is a critical part of making a rapid transition to clean energy, including meeting the Biden administration’s goals of a carbon pollution-free power sector by 2035 and net-zero emissions economy-wide no later than 2050. This report by the Ocean Conservancy outlines a series of recommendations that, if implemented, would significantly increase the effectiveness, efficiency, and regulatory certainty of the U.S. offshore wind planning and permitting system and, in so doing, maximize both the deployment of offshore wind and the overall health and sustainability of ocean ecosystems. These recommendations are built on the foundation of lessons learned from working to permit offshore wind over the past decade as well as discussions with experts in federal ocean policy, federal agency permitting staff, and ocean users, including those from the conservation, maritime, and fishing industries.

Duke, TotalEnergies winning bidders in wind lease auction

Federal officials Wednesday auctioned two lease areas off the North Carolina and South Carolina coast, the second major offshore wind lease sale of 2022. The provisional winner for renewable energy lease No. OCS-A 0545, the westernmost, 54,937-acre section of the Carolina Long Bay area was TotalEnergies Renewables USA, LLC, which bid $160 million. Duke Energy Renewables Wind, LLC was the provisional winner for lease No. OCS-A 0546, a 55,154-acre area, with a $155 million bid.

The Bureau of Ocean Energy Management says the two sections together, if developed, could generate 1.3 gigawatts or more, enough to power nearly 500,000 homes. 

How will offshore wind energy affect marine life in the Gulf? Feds are taking a look

The U.S. Bureau of Ocean Energy Management, the federal agency that oversees offshore oil, gas and wind permitting, has begun crafting a draft environmental assessment for a 30 million-acre area stretching from the Mississippi River to the Texas-Mexico border. The assessment will consider how the construction and operation of offshore wind turbines affects fisheries, marine mammals, birds and other elements of the marine environment. BOEM plans to narrow its assessment area based on input from wind energy developers, fishers and other groups.

The Gulf has the potential to generate more than 500,000 megawatts of offshore wind energy per year, according to the National Renewable Energy Laboratory. That’s twice the current energy needs of all five Gulf states, and larger than the potential offshore wind capacity of the Pacific Coast and Great Lakes combined.

Year-Round Spatiotemporal Distribution of Harbour Porpoises Within and Around the Maryland Wind Energy AreaIncorporating more than 18 months of harbour porpoise detection data from passive acoustic monitoring, generalized auto-regressive moving average and generalized additive models were used to investigate harbour porpoise occurrence within and around the Maryland WEA in relation to temporal and environmental variables. Acoustic detection metrics were compared to habitat-based density estimates derived from aerial and boat-based sightings to validate the model predictions. Harbour porpoises occurred significantly more frequently during January to May, and foraged significantly more often in the evenings to early mornings at sites within and outside the Maryland WEA. The acoustic detections were significantly correlated with the predicted densities, except at the most inshore site. 2017
An Assessment of the Economic Potential of Offshore Wind in the United States from 2015 to 2030This study describes an assessment of the site-specific variation of levelized cost of energy (LCOE) and levelized avoided cost of energy (LACE)to understand the economic potential of fixed-bottom and floating offshore wind technologies in major U.S. coastal areas between 2015 and 2030. The study documents in detail the variation in economic potential across more than 7,000 U.S. coastal locations by comparing site-specific LCOE and LACE. In particular, this study offers insights into the available U.S. offshore wind resource by region at different levels of LCOE and an assessment of the present and future economic potential of that resource capacity out to 2030. 2017
Geophysical potential for wind energy over the open oceansWind speeds over open ocean areas are often higher than those in the windiest areas over land, which has motivated a quest to develop technologies that could harvest wind energy in deep water environments. However, it remains unclear whether these open ocean wind speeds are higher because of lack of surface drag or whether a greater downward transport of kinetic energy may be sustained in open ocean environments. Focusing on the North Atlantic region, we provide evidence that there is potential for greater downward transport of kinetic energy in the overlying atmosphere. As a result, wind power generation over some ocean areas can exceed power generation on land by a factor of three or more. 2017
Obligations and aspirations: A critical evaluation of offshore wind farm cumulative impact assessmentsTo investigate how robust current cumulative impact assessment practice is, a novel evaluation framework was developed and applied to Environmental Statements of the world's largest offshore wind farms, currently in United Kingdom waters. The framework was designed to evaluate cumulative impact assessments relative to the information needs of decision-makers tasked with managing cumulative effects. We found that current practice does not meet those needs, that there is dissonance between science and practice, and problematic variability between assessments was observed. Straightforward recommendations for improved practice are provided, which if implemented may ease the perceived regulatory burden by clarifying practice. We also highlight additional steps that could enable project-led cumulative impact assessments to better support regional marine management. 2017
The challenge of integrating offshore wind power in the U.S. electric grid. Part II: Simulation of electricity market operationsThe purpose of this two-part study is to analyze large penetrations of offshore wind power into a large electric grid, using the case of the grid operated by PJM Interconnection in the northeastern U.S. Part I of the study introduces the wind forecast error model and Part II, this paper, describes Smart-ISO, a simulator of PJM's planning process for generator scheduling, including day-ahead and intermediate-term commitments to energy generators and real-time economic dispatch. Results show that, except in summer, an unconstrained transmission grid can meet the load at five build-out levels spanning 7–70 GW of capacity, with the addition of at most 1–8 GW of reserves.2017
2015 Wind Technologies Market ReportThis annual report—now in its tenth year—provides a detailed overview of developments and trends in the U.S. wind power market, with a particular focus on 2015. Annual wind power capacity additions in the United States surged in 2015 and are projected to continue at a rapid clip in the coming five years. Recent and projected near-term growth is supported by the industry’s primary federal incentive—the production tax credit (PTC)—as well as a myriad of state-level policies. Wind additions are also being driven by improvements in the cost and performance of wind power technologies, yielding low power sales prices for utility, corporate, and other purchasers. At the same time, the prospects for growth beyond the current PTC cycle remain uncertain: growth could be blunted by declining federal tax support, expectations for low natural gas prices, and modest electricity demand growth. 2016

Establishing a legal research agenda for ocean energyThe literature on ocean energy has, to date, largely focused on technical, environmental, and, increasingly, social and political aspects. Legal and regulatory factors have received far less attention, despite their importance in supporting this new technology and ensuring its sustainable development. Building on the social sciences research agenda developed by the International network for Social Studies of Marine Energy (ISSMER) and published in Energy Policy, a complementary agenda for legal research linked to ocean energy was set out. Key directions for future research structured around the core themes of marine governance: (i) international law; (ii) environmental impacts; (iii) rights and ownership; (iv) consenting processes; and (v) management of marine space and resources were identified.2016
The challenge of integrating offshore wind power in the U.S. electric grid. Part I: Wind forecast errorThe purpose of this two-part study is to model the effects of large penetrations of offshore wind power into a large electric system using realistic wind power forecast errors and a complete model of unit commitment, economic dispatch, and power flow. The chosen electric system is PJM Interconnection, one of the largest independent system operators in the U.S. with a generation capacity of 186 Gigawatts (GW). The offshore wind resource along the U.S. East Coast is modeled at five build-out levels, varying between 7 and 70 GW of installed capacity, considering exclusion zones and conflicting water uses.This paper, Part I of the study, describes in detail the wind forecast error model.2016
Offshore Energy by the Numbers, an Economic Analysis of Offshore Drilling and Wind Energy in the AtlanticOceana, an international organization focused solely on protecting oceans, produced an analysis which finds that the economic benefits of offshore drilling in the Atlantic projected by the oil and gas industries appear to be exaggerated due to the inclusion of oil and gas resources that are not economically recoverable, thereby inflating the potential benefits. Industry estimates also rely upon an assumption of a state revenue-sharing system that does not exist. Oceana’s report also finds that offshore oil and gas development along the Atlantic could put at risk some of the nearly 1.4 million jobs and over $95 billion in gross domestic product that rely on healthy ocean ecosystems, mainly through fishing, tourism and recreation. The report includes fact sheets for seven Mid-Atlantic and Southeastern states including Georgia.2015
Sound exposure in harbor seals during the installation of an offshore wind farm: predictions of auditory damageWe report on a behavioral study during the construction of a wind farm using data from GPS/GSM tags on 24 harbor seals Phocavitulina L. Pile driving data and acoustic propagation models, together with seal movement and dive data, allowed the prediction of auditory damage in each seal. Growth and recovery functions for auditory damage were combined to predict temporary auditory threshold shifts in each seal. Comparison to exposure criteria suggests that half of the seals exceeded estimated permanent auditory damage thresholds. 2015

Wind Turbines: the Bigger, the BetterThe average hub height for offshore turbines in the United States is projected to grow from 330 feet (100 m) in 2016 to about 500 feet (150 m), or about the height of the Washington Monument, in 2035.2021
Wind Turbines in Extreme Weather: Solutions for Hurricane ResiliencyAlthough hurricanes and the damage they can cause remain difficult to predict, with current R&D, the Energy Department is taking steps to alleviate potential risks to offshore wind systems that will eventually be deployed in the southeastern and mid-Atlantic regions2018
Offshore wind farms could protect coastlinesOffshore wind farms may have a greater capacity for coastal protection than first imagined. Simulations featuring data from Hurricane Harvey suggest that smart wind farm designs have the capacity to protect coastlines from heavy rains.2018
Wind On The Waves: Floating Wind Power Is Becoming A RealityResearchers and engineers are finding ways to create platforms that float, while giving the top-heavy turbine enough stability to operate effectively. Tethered to the sea floor, floating foundations allow wind turbines to operate in areas where water depths may be greater than 165 feet. This technology, is already successful at the prototype stage, with more extensive test and demonstration projects underway. 2017
U.S. Conditions Drive Innovation in Offshore Wind FoundationsAs offshore wind projects move further from shore, jacket structures, which typically consist of four legs connected by braces, are becoming more common. Block Island—the first U.S. offshore wind farm—used a “gulf-style” jacket foundation with an installation method adapted from the offshore oil and gas industry.2017
Offshore Wind Moves into Energy’s MainstreamAs offshore wind technology has improved and demand for renewable energy has risen, costs have fallen, making it more attractive to financial investors. 2017

Wind Technology Resource CenterThe Wind Technology Resource Center (WTRC) provides a central repository for research reports, publications, data sets, and online tools developed by DOE’s national laboratories and facilities. These information resources detail wind-energy-related analyses, studies, technology design, tests, and field experiments conducted by the labs from 1980 to the present. The WTRC offers a variety of ways for users to browse resources, including by topic, technology, application, and state, or search based on keywords. Visitors to the resource center can begin their search with a keyword and continue narrowing the field using a host of filters on the results page. In addition to R&D topics, technology, application, and state, users can filter by organization and resource type to create a highly tailored list.N/A
