The government probe of July's wind farm death in Sibley, Iowa, is still under way, but both the project developer and the wind turbine supplier are describing the incident as a crane accident, not caused by their procedures. Nonetheless, Greg Jaunich of developer Northern Alternative Energy (NAE) says the company will change its procedure and probably keep people at the site a "crane's height" in distance away while heavy equipment is being installed. The fatal accident occurred when a crane carrying a Micon nacelle stalled then toppled over. Leif Anderson, president of Micon Wind Turbines (US) Inc, says a new nacelle should arrive at the site to replace the damaged one in September. The government probe is routine after a work related death.
