Crews respond to wind turbine fire in Huron County

Firefighters and deputies were called after a wind turbine caught fire near the village of Elkton. Jeff Smith, an Elkton village official, said the fire, which broke out on April 1,  is 300 feet in the air and crews cannot reach it to extinguish the blaze. The turbine is part of the Harvest II wind energy facility placed in service in November 2012 by Exelon and is one of 33 Vestas V-100 (1.8 MW) turbines erected in Oliver, Chandler and McKinley townships.
