A fire at the Hibbing Public Utilities Power Plant caused $70,000 in damage on Sunday. According to Hibbing Fire Marshal Bryan Fagerstrom, the blaze broke out at the top of a 5-story conveyer belt on the bio-mass side of the power plant just after 2:30 p.m. “The conveyor carried wood chips to a loading area to be burned for steam generation,” the press release said. It was equipped with a sprinkler system which assisted in controlling the fire. Crews from Hibbing, Chisholm and Keewatin remained on the scene for several hours to ensure all the hot spots were extinguished. No one was injured. The fire appeared to have been caused by a bearing failure on the conveyor belt.
