Blade failure at Grand Ridge wind site

Two turbines at the 100.5 MW Grand Ridge Energy wind facility in La Salle County, Illinois, about 80 miles southwest of Chicago, experienced blade failures on July 23-24, 2010. A spokeswoman for Invenergy Wind said that, in the event of high winds, the turbines are designed to come to rest with one blade pointing down and parallel to the base of the tower. According to Invenergy, the winds came so quickly that the safety mechanism did not have time to engage.
