OAKWOOD — For the third time in 17 months, a wind turbine blade manufactured by General Electric has broken off at an East Central Illinois wind farm. The latest incident occurred about 9 p.m. Nov. 20 in Vermilion County at the California Ridge Wind Farm operated by Chicago-based Invenergy. Another turbine blade broke in that same wind farm in November 2012, following a June 2012 blade break at the Settlers Trail Wind Farm near Sheldon, operated by Chicago-based E.On Climate & Renewables.
All three blades were on 1.6-megawatt turbines manufactured by GE. “We are working with GE, the turbine manufacturer, to determine the cause of this incident,” a statement from Invenergy said Friday. Last March, GE issued a statement saying that an “isolated manufacturing issue” caused the two wind turbines to break in 2012. GE said it had “reviewed the wind farm fleets at both sites to ensure their continued reliability and performance” and “have addressed the manufacturing issue to prevent this from happening in the future.”
GE officials did not immediately return a call requesting comment on the latest incident. Invenergy said the blade broke off and fell to the ground near the base of the turbine, which is located near the intersection of 2150 North Road and 900 East Road near Oakwood. Read article
