New Interactive Tools Explore Data from Annual DOE Wind Power Reports

In conjunction with the release of the annual Wind Technologies Market Report, prepared for the US Department of Energy, Berkeley Lab has produced a series of interactive data tools that allow users to explore the data from the report.

To prepare the report, Berkeley Lab researchers compile the most comprehensive set of data on performance, cost and prices, market growth, and technology trends for wind projects, at both the project and state level.

The interactive visualizations provide access to the data, allowing the user to easily focus on specific geographic areas, time periods, or attributes of wind energy deployment in the United States. Users can apply filters to show subsets of data, zoom in on regions, and see project level information by mousing-over a point. No programming or spreadsheet skills are required.

The visualizations cover:


A set of maps that show the growth of wind power by state over time, showing the annual and cumulative capacity installed, plus the percent of in-state generation.


Maps that show the 2017 capacity factors for 825 projects built between 1998 and 2016, by project and by state averages. Project locations are overlaid on a map of wind resources from the National Renewable Energy Lab.

Contract prices

A bubble chart that shows power purchase agreement (PPA) prices since 1996 for over 430 projects, color-coded by region. 

Technology trends

Maps that show how generator size, hub height, rotor diameter, and specific power vary by location and over time.

Specific power

A dashboard that explains the importance of specific power, which is the relationship between the output of the generator and the size of the rotor.

The visualizations are posted here, along with the full report, a presentation slide deck that summarizes the report, and an Excel workbook that contains data from the report. The visualizations are public domain, and can be embedded in articles and blog posts.

Additional visualizations are available for the 2016 Utility-Scale Solar report, which tracks progress for solar power projects greater than one megawatt in size. They will be updated in September 2018, when the 2017 edition of the report is released.

Berkeley Lab’s contributions to the report were funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy.

Dr. Ryan H. Wiser is a Senior Scientist and Deputy Group Leader in the Electricity Markets and Policy Group at Lawrence Berkeley National Laboratory. Ryan leads and conducts research and analysis on renewable energy, including on the planning, design, and evaluation of renewable energy policies; on the costs, benefits, and market potential of renewable electricity sources; on electric grid operations and infrastructure impacts; and on public acceptance and deployment barriers. His recent analytic work has included studies on the economics of wind and solar power; the impacts of higher penetrations of renewable energy on the electricity sector; the design of renewable energy promotion policies; the risk mitigation value of renewable electricity; the treatment of low-carbon supply options in utility resource planning; and community acceptance of wind and solar power.   The Electricity Markets and Policy Group (EMP) of the Lawrence Berkeley National Lab conducts technical, economic, and policy analysis of energy topics centered on the U.S. electricity sector. Our current research seeks to inform public and private decision-making on public-interest issues related to energy efficiency and demand response, renewable energy, electricity resource and transmission planning, and electricity reliability.
