2016 Wind Technologies Market Report

摘要: Author(s): Ryan H. Wiser; Mark Bolinger | Abstract: The U.S. Department of Energy (DOE)’snWind Technologies Market Reportnprovides an annual overview trends in the wind power market. You can find report, a presentation, and data file on Files tab, below. Additionally, several visualizations are available Data Visualizations tab. Highlights this year’s report include:Wind additions continued at rapid clip 2016:n$13 billion was invested new plants 2016. In 2016, energy contributed 5.6% nation’s electricity supply, more than 10% total generation fourteen states, 29% to 37% three those states—Iowa, South Dakota, Kansas.Bigger turbines enhancing project performance:nIncreased blade lengths, particular, have dramatically increased capacity factors, one measure performance. For example, average 2016 factor among projects built 2014 2015 42.6%, compared 32.1% from 2004 2011 25.4% 1998 2001.Low turbine pricing continues push down installed costs:nWind prices fallen their highs 2008, $800–$1,100/kW. Overall, cost $1,590/kW, $780/kW peak 2009 2010.nWind remain low:nAfter topping out nearly 7¢/kWh for purchase agreements (PPAs) executed 2009, national price PPAs has dropped around 2¢/kWh—though nationwide is dominated by that hail lowest-priced Interior region country (such as Texas, Iowa, Oklahoma). These prices, which possible part due federal tax support, compare favorably projected future fuel costs gas-fired generation. nThe supply chain adjust swings domestic demand equipment:nWind sector employment reached high 101,000 full-time workers end recently U.S., domestically manufactured content highest nacelle assembly (g90%), towers (65-80%), blades hubs (50-70%), but much lower (l20%) most components internal turbine.Continued strong growth anticipated near term:nWith incentives still available, though declining, various forecasts market show expected averaging 9,000 MW/year 2017 2020.
