Each turbine stands 214 feet (65 m) tall and has a diameter of 171 feet (52 m) across the rotor, the two ton rotors spin at 25 rpm.[1] Each of the three blades measure 83 ft (25.91 m) long.[1] The turbine towers are spread out over 2,200 acres (890 ha) of Lee County, Illinois, near the village of Paw Paw and adjacent to Interstate 39. The wind farm was developed by Navitas Energy, and is now owned and operated by Leeward .[2] Energy produced at Mendota Hills is sold to Commonwealth Edison.[3] Each tower has a 2.5 megawatt capacity giving a total capacity at Mendota Hills Wind Farm of 72.6 megawatts.[1] The site produces enough power (approximately 110 million kilowatt hours annually) to power about 13,000 homes.[3] 29 SG126-2.5's were put up on their place in 2019[4]

The Mendota Hills Wind Farm's beginnings are rooted in the spring of 2002 when land owners were first approached about the wind towers. For the two years previous to that wind metering had been taking place in the area where the wind farm is located today. Construction could only begin, in June 2003, after a series of environmental and archaeological tests and approval from the Lee County Zoning Board.[1] Construction on the wind farm was complete by November 2003 and the Mendota Hills Wind Farm officially went online on November 24, 2003.[3] Landowners and farmers are compensated by the developer, Navitas Energy of Minneapolis, Minnesota, on a contractual basis. Most landowners are paid US$1,200 to $1,500 per megawatt of electricity produced on each tower.[1]
