Wind power in Illinois

Mendota Hills Wind Farm in northern Illinois

Wind power in Illinois provided 4.7% of the state's electrical power in 2013.[1] At the end of 2012, Illinois had 3568 megawatts (MW) of wind power installed,[2][3] ranking fourth among states for installed wind turbine capacity.[4][5] The vast majority of wind-generated electricity in Illinois is distributed via Midcontinent Independent System Operator, which services Illinois outside of Chicagoland--as opposed to PJM Interconnection, which distributions electricity in the Chicago metropolitan area.

Wind power has been supported by a renewable portfolio standard, passed in 2007, and strengthened in 2009, which requires 10% renewable energy from electric companies by 2010 and 25% by 2025.[6] For 2013, in-state renewable generation was just 5.1% of Illinois' total generation.[7]Additional renewably generated electricity is imported from other states.[8] Illinois uses a large amount of electricity, and the state's mandate was enacted when only a very small percentage of its electricity was renewably generated.

Illinois has the potential for installing up to an estimated 249,882 MW of wind generation capacity at a hub height of 80 meters operating at 30% gross capacity factor.[9][10]That amount is lower with higher capacity factors and is higher with 100 meter hub heights.[10]

The first wind farm in Illinois opened in 2003 and by 2009, it had over 1800 MW installed statewide with thousands of MW more in the planning stages.[11] The largest wind farm in the state is the 300 MW Cayuga Ridge installation, while another seven windfarms each exceeded 100 MW capacity.[5] The Twin Groves Wind Farm was the largest wind farm east of the Mississippi when completed but has since been surpassed.[12][13] Some smaller installations include a 0.66 MW turbine at the Bureau Valley School District and a 2.5 MW turbine at the Illinois Sustainable Technology Center, formerly part of the Illinois Department of Natural Resources, now part of the University of Illinois.[5] A proposed high voltage DC transmission line would transmit wind generated electrical power to the Chicago area from northwest Iowa.[14]
