Largest wind power projects in the United States 2019

Based in the southwestern region of the Mojave desert, the Alta Wind Energy Center is the largest wind power project in the United States by installed capacity, at approximately 946 megawatts as of 2019. The Roscoe Wind Project in Sweetwater, Texas, is the fifth-largest U.S. wind project, and previously was the largest wind farm in the world before the construction of California’s Alta Center.

Texas leads for wind power

The majority of the largest U.S. wind power projects are located in Texas, with the Horse Hollow Center, Sweetwater Windpower, and Buffalo Gap Wind Farm filling out the top facilities. Texas is the leading state in terms of cumulative wind power capacity. Land availability is a major factor in Texas’s dominance in the U.S. wind market and land is often leased by private owners to for-profit energy companies.

Wind market growth in the U.S.

Cumulative installed wind power capacity in the United States has drastically increased in the past decade. This is in part due to greater investment in clean energy , especially after the 2008 Recession when oil prices spiked and the development of other renewable sources became more lucrative. Among renewable resources, solar generation has seen a larger increase than wind power over the last decades.
