The state of South Dakota led the U.S. in wind power generation with 22.3% of the state's electricity generation coming from wind in 2011. South Dakota has over 800 megawatts (MW) of wind generation capacity.
South Dakota is one of the country's windiest states, and has the potential of installing 882,000 MW, and generating 2,902 billion kWh/year. Just as in Texas, the construction of new wind farms is transmission line limited.
South Dakota's first wind farm was the South Dakota Wind Energy Center, built in 2003.
