Adair County Iowa Arbor Hill industrial wind turbine blade failure
MidAmerican's Arbor Hill wind energy facility suffered a failure when a portion of a 177-foot long blade broke off the turbine and was flung onto another farmer's property. A similar blade break occurred at a month later at the Beaver Creek wind farm, also owned and operated by MidAmerican. Both the Arbor Hill and Beaver Creek facilities have Vestas V110 2.0 MW turbines installed.
