In some wintry conditions, ice can accumulate on turbine blades. Sophisticated vibration sensors on the turbine blade automatically shut the turbine down when this occurs. In almost all cases, ice drops straight to the ground, just like icicles or snow sliding off a roof. Apex exceeds minimum setback requirements to make absolutely certain ice is not a risk to neighboring structures.
