Did blowing winds break the blades?

Miner said crews are examining the two towers to see if there is any damage to other components. At any rate, a crane will be brought in and the blades replaced. The replacement process will take at least a few weeks. About one year ago, another blade broke in the same area. In that case, high wind caused the damage.

This week, repair crews are inspecting two damaged wind towers in southeastern La Salle County.

A fiberglass blade on a tower about six miles east of Grand Ridge and a blade on one near Marseilles each broke in half Saturday morning. Laura Miner, a spokeswoman for Invenergy Wind, said high winds Friday evening might have weakened the blades, causing them to break the next morning. Miner said if they were damaged Friday, the damage could not have been serious, because there are sensors on the towers that would have indicated serious damage, and there were no such indications.

"They shut off immediately. If anything, debris would have dropped straight down. And they're in the middle of fields, so there's no people or animals around."

Miner also pointed out the two damaged blades remained attached to the towers.

Blades shut down when the wind reaches a certain speed, but Miner did not know that speed. She did say some of the towers shut down during the storm Friday. Towers also can turn so they are not facing the wind, in a precaution called "feathering."
