Wind Power costs at 2 cents per kilowatt hour
Key findings from the U.S. Department of Energy's Wind Technologies Market Report include:
Wind power capacity additions continued at a rapid pace in 2017. Nationwide, wind power capacity additions equaled 7,017 megawatts (MW) in 2017, with $11 billion invested in new plants. Wind power constituted 25 percent of all U.S. generation capacity additions in 2017. Wind energy contributed 6.3 percent of the nation's electricity supply, more than 10 percent of total electricity generation in 14 states, and more than 30 percent in four of those states (Iowa, Kansas, Oklahoma, and South Dakota).
Low wind turbine pricing continues to push down installed project costs. Wind turbine equipment prices have fallen to $750-$950/kilowatt (kW), and these declines are pushing down project-level costs. The average installed cost of wind projects in 2017 was $1,610/kW, down $795/kW from the peak in 2009 and 2010.
