2018 Cost of Wind Energy Review

This report uses representative utility-scale projects to estimate the levelized cost of energy (LCOE) for land-based and offshore wind power plants in the United States. Data and results detailed here are derived from 2018 commissioned plants. Analysis detailed here relies on recent market data and state-of-the-art modeling capabilities to maintain an up-to-date understanding of wind energy cost trends and drivers. This report represents the eighth annual installment and is intended to provide insight into current component-level costs as well as a basis for understanding variability in LCOE across the country.

2019 Annual Technology Baseline [Slides]

Consistent cost and performance data for various electricity generation technologies can be difficult to find and may change frequently for certain technologies. With the Annual Technology Baseline (ATB), the National Renewable Energy Laboratory annually provides an organized and centralized set of such cost and performance data. The ATB uses the best information from the Department of Energy national laboratories' renewable energy analysts as well as information from the Energy Information Administration for fuel-based technologies. The ATB has been reviewed by experts and it includes the following electricity generation technologies: land-based wind, offshore wind, utility-scale solar photovoltaics (PV), commercial-scale solar PV, residential-scale solar PV, concentrating solar power, geothermal power, hydropower, utility-scale battery storage, coal, natural gas, nuclear, and conventional biopower. This webinar presentation introduces the 2019 ATB.

IEA Wind TCP Task 26: Offshore Wind Energy International Comparative Analysis

Task 26 'Cost of Energy' has been running within the International Energy Agency (IEA) Wind Technology Collaboration Programme since 2009. In 2015, task participants produced IEA Wind Task 26: Offshore Wind Farm Baseline Documentation (Smart et al. 2016), published in 2016 to document the technical and cost assumptions and levelized cost of energy (LCOE) results for a generic, geographically nonspecific, baseline offshore wind farm being commissioned in 2012-2014. This report has been prepared to document changes to offshore wind costs and technology since the baseline and as an analysis of the drivers of LCOE between countries. This report examines the physical site characteristics, technology choices, and regulatory context driving LCOE in key countries for offshore wind farms being commissioned in 2017-2018.

IEA Wind TCP Task 26–Wind Technology, Cost, and Performance Trends in Denmark, Germany, Ireland, Norway, Sweden, the European Union, and the United States: 2008-2016

The International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) Task 26 - The Cost of Wind Energy represents an international collaboration dedicated to exploring the past, present, and future cost of wind energy. The countries that are currently represented by participating organizations in IEA Wind TCP Task 26 included in this report are Denmark, Germany, Ireland, Norway, Sweden, the European Union, and the United States. This report discusses trends from 2008 through 2016 that affected the cost of land-based wind energy in each country. The cost of wind energy during this period is compared with the market value of wind energy in the respective electricity market for each country. This report builds from previous analysis conducted since the inception of Task 26 in 2009. Schwabe et al. (2011) explored differences in the cost of wind energy in 2008 among countries participating in Task 26 at that time. Vitina et al. (2015) presented turbine- and project-level trends in the wind industry from 2008 to 2012, including wind project size, turbine size, specific power and hub height, project performance, investment costs, operation and maintenance (O&M) costs, and project financing. These inputs are used to calculate the levelized cost of energy (LCOE), a widely recognized metric for understanding how technology performance, capital investment, operations, and financing impact the life cycle cost of building and operating a wind project. Both prior reports - as well as this report - used this metric to estimate the cost of wind energy.
