Grand Ridge Wind Energy Center in LaSalle County, Illinois, is Invenergy's 210 MW wind portion of a 34,000-acre, 266 MW site that also holds 20 MW of solar and 36 MW of battery storage. Phase one reached commercial operation in April 2008, and three wind expansions followed through 2010, including GE 1.5 MW turbines. Invenergy added solar in 2012 and storage in 2016, making it the company's first site co-locating all three technologies. The Grand Ridge II phase sells to Appalachian Power Company.
