CEDAR RAPIDS, Iowa (April 30, 2019) – ITC will be conducting semi-annual aerial patrols of high-voltage transmission structures and lines throughout its service territory from approximately May 13-24, weather permitting. Helicopter patrols provide an overall status of the overhead transmission system owned and operated by ITC’s Iowa-based operating entity, ITC Midwest LLC.
The aerial inspections will cover the company’s lines in east central and southeast Iowa, as well as extreme northwestern Illinois and one county in Missouri. The flights will be conducted in the Burlington, Cedar Rapids, Clinton, Dubuque, Fort Madison, Iowa City, Keokuk, Marengo, Marion, Palo and Vinton areas in Iowa as well as the Galena, Illinois and Wayland, Missouri areas. Iowa counties in the aerial patrol areas include Benton, Buchanan, Cedar, Clinton, Delaware, Des Moines, Dubuque, Henry, Iowa, Jackson, Johnson, Jones, Linn and Louisa, as well as Carroll, Jo Davies, Hancock, Rock Island and Whiteside counties in Illinois and Clark County in Missouri.
These patrols are a North American Electrical Reliability Corporation (NERC) requirement for ITC’s vegetation management program, support proactive maintenance objectives, and align with the company’s model for operational excellence. They include inspections of steel structures, wood poles, conductors (wires), insulators and other equipment. Crews check for damaged or worn equipment and vegetation hazards.
The inspection flights are often conducted at low altitudes to allow accurate visual inspection of equipment for lightning damage, wear or other potential problems. This is normal procedure, so there is no cause for alarm if a low-flying helicopter is sighted near transmission lines during the time frame listed above.
