OCOTILLO — The operator of the wind farm near here has released the reason for the September collapse of a 300-foot-high turbine and measures it will take in an effort to prevent further such failures.

“The cause was an external crack that formed in a turbine blade,” Ocotillo Wind facility manager Tony Welsh stated in a Dec. 10 letter released to this newspaper on Jan. 7. “To prevent this from reoccurring, the site team will conduct frequent external blade inspections using drones, in addition to regularly scheduled internal blade inspections.”
