Distributed Wind

Distributed energy resources—technologies used to generate, store, and manage energy consumption for nearby energy customers—can help increase power system reliability while providing energy locally. The Wind Energy Technologies Office’s (WETO) distributed wind research program is advancing wind energy technology as an accessible, affordable distributed energy resource option for consumers.

What Is Distributed Wind?

Explore the potential use cases of distributed wind energy in your local community, including in residential, commercial, industrial, agricultural, and public facilities. Distributed wind energy has the potential to diversify local energy sources to help provide renewable energy in your community.

Wind turbines used as a distributed energy resource—known as distributed wind—are connected at the distribution level of an electricity delivery system (or in off-grid applications) to serve on-site energy demand or support operation of local electricity distribution networks.

Distributed wind installations can range from a less-than-1-kilowatt off-grid wind turbine powering telecommunications equipment, to a 15-kilowatt wind turbine at a home or small farm or a 100-kilowatt wind turbine at a university campus or industrial facility. Distributed wind can also be several multimegawatt wind turbines owned by a local community, the local electricity distribution utility, or a manufacturing facility.

Individuals, businesses, and communities install distributed wind energy to offset retail power costs or secure long-term power cost certainty, support grid operations and local loads, enhance reliability with backup power, and electrify remote properties and infrastructure not connected to a centralized grid.

Distributed Wind Research Program Goals

Distributed wind technologies can supply rural homes, businesses, and communities with locally produced energy that can provide cost savings. WETO’s research and development, or R&D, efforts aim to maximize confidence in turbine performance and safety (by increasing the number of small and medium wind turbine designs tested to national performance and safety standards) and to improve distributed wind energy’s cost effectiveness (by reducing its levelized cost of energy [LCOE]). Achieving these goals can inform consumer adoption and deployment.  

WETO’s Multi-Year Program Plan outlines the Office’s research priorities and plans through the year 2025, including those for distributed wind.

Current Research Highlights

WETO supports a portfolio of interrelated R&D efforts with the U.S. Department of Energy’s (DOE) national laboratories as well as academia and industry stakeholders. In addition, WETO supports leading edge, world-class test facilities and research capabilities at the national laboratories.

WETO’s distributed wind research program focuses on six primary areas to advance wind energy technology as a distributed energy resource:

Data, Analysis, and Modeling

While distributed wind stakeholders may often focus on their individual companies, research, or product development, WETO approaches distributed wind analysis and modeling holistically, looking at transformative solutions for the entire industry. WETO develops and disseminates independent, fact-based distributed wind data, analysis, and modeling tools to educate stakeholders, support the identification and prioritization of WETO’s research and development efforts, and to address research needs that cannot be met at the individual level.

Distributed Wind Deployment

WETO is involved in a variety of strategic and technical stakeholder engagement activities to enable the development, deployment, and integration of distributed wind. WETO has the ability to convene domestic and international stakeholders to address topics critical to advancing wind energy solutions. Ongoing strategic engagement allows WETO to understand industry needs, research needs, and how research projects can best be tailored to maximize the impact of federal (taxpayer) funding. 

For distributed wind to realize its potential contribution to affordable and reliable energy, consumers and stakeholders need support to evaluate, develop, and operate distributed wind systems and hybrid systems (e.g., wind energy technology combined with other distributed energy resources, such as batteries or solar). Many U.S. regions that have quality wind resources, high retail electricity rates, and population densities acceptable for all scales of distributed wind deployment are rural. To date, however, rural electric utilities and the communities they serve have experienced limited distributed wind deployment due to a lack of resources and tools to support decision making. To address these gaps, WETO launched its Wind Innovations for Rural Economic Development (WIRED) initiative with a workshop to learn about the unique needs, challenges, and experiences rural electric cooperatives and communities have with distributed wind. WIRED supports the creation of decision support tools and other resources that rural electric utilities and communities can use to develop distributed wind projects. 

Strategize, Engage, Network, and Deploy Distributed Wind 

Technical, economic, market, and performance barriers have limited distributed wind’s contributions to the domestic energy portfolio and reduced stakeholder confidence and interest in distributed wind. The Strategize, Engage, Network, and Deploy (SEND) Distributed Wind project engages with stakeholders to expand stakeholders’ knowledge of distributed wind opportunities and access to deployment support, to increase stakeholder confidence, and to lay the groundwork for a future workforce that can support distributed wind deployment.  

The National Distributed Wind Network is a convening platform for distributed wind stakeholders from around the country to coordinate, collaborate, and learn from peers and leading experts. The Distributed Wind Resource Hub includes general information about distributed wind energy, project funding and technical assistance opportunities, case studies of successful distributed wind energy projects, and models, tools, and toolkits to help users assess their location for distributed wind energy. The SEND resources support the Rural and Agricultural Income & Savings from Renewable Energy (RAISE) Initiative, which has an initial goal of helping 400 individual farmers deploy smaller-scale wind projects.

Systems Integration

Controls and power electronics hardware to integrate wind energy technologies with other distributed energy resources and into distribution grids, microgrids, and hybrid systems are not well developed or standardized. In addition, the tools used to inform decision making around grid system planning and operations often do not fully characterize distributed wind compared to other distributed energy resources. As contributions from variable renewable resources have increased on microgrids and distribution grids, the need for wind to integrate in a seamless plug-and-play manner with other distributed energy technologies is critical for consumer adoption.

WETO’s research in distributed wind systems integration seeks to develop and validate wind technology as a plug-and-play resource with solar, storage, and other distributed energy resources to support grid system reliability. Through the WIRED initiative, WETO is supporting research to optimize the integration and operation of distributed wind with other distributed energy resources. The goal is to strengthen rural electricity distribution networks and provide additional grid support services. WETO is also supporting foundational research in advanced turbine controls, valuation of grid support services, and approaches for enhancing cybersecurity.

Small and Medium Wind Turbine Technology R&D

Small wind turbine technology is commonly defined as turbines with rated capacity of less than or equal to 100 kilowatts. Medium wind turbine technology is commonly defined as turbines with rated capacity of greater than 100 kilowatts and less than or equal to 1 megawatt. Because small and medium wind turbine technologies deployed today are exclusively used in distributed applications, they are the primary wind turbine technology R&D focus areas in the distributed wind research program.

Cost reduction and power performance improvements are critical for small and medium wind turbine technologies to remain an economically viable distributed energy resource option. In addition, turbine testing for certification to national performance and safety standards is an essential step to qualify new technology for commercialization and incentive programs. However, testing turbines to rigorous standards is time intensive and can hinder a small company’s ability to take its product to the market.  Consequently, WETO’s research and support aims to address this potential market barrier and advance small and medium wind turbine technology as cost competitive, compatible, and reliable distributed energy resource options.

Resource Assessment

Accurately and cost-effectively predicting the power performance of distributed wind installations, particularly those using small wind turbine technology, is a technical challenge. Consequently, consumers and policymakers have less confidence in small-scale distributed wind and small wind projects tend to have high project development costs. The cost and long timeframes of current measurement-based wind resource assessments used by large wind farm developers are not suitable for small wind installers and developers. This often forces small-wind installers and developers to use rule-of-thumb methods and simplified model-based approaches instead, leading to uncertainty in the estimates and a tendency to overestimate production.

The resource assessment focus area of the distributed wind research program aims to provide data, modeling tools, and information to help customers and stakeholders evaluate the quality of the wind resource in their region, territory, and backyard. In doing so, WETO is striving to reduce the cost and time required to develop a wind resource estimate while increasing the accuracy. 

Stakeholder Engagement

WETO has the ability to convene domestic and international stakeholders to address topics critical to advancing wind energy solutions. Ongoing strategic engagement allows WETO to understand industry needs, research needs, and how research projects can best be tailored to maximize the impact of federal (taxpayer) funding. As a result, WETO is involved in a variety of strategic and technical stakeholder engagement activities to accelerate the development, deployment, and integration of distributed wind.
