NOVI — ITC Holdings Corp., the nation’s largest independent electricity transmission company based in Novi, Michigan, will be conducting aerial patrols of the high-voltage transmission structures and lines in Michigan from approximately May 16 – June 3, weather permitting. The helicopter patrols are conducted to provide an overall status of the overhead transmission system that is operated by ITC’s Michigan operating entities, ITCTransmission and Michigan Electric Transmission Company, LLC.
Please note, the helicopters will be flying lower than usual near the transmission lines during these inspections, which is no cause for concern for area residents.
The aerial inspections will cover nearly all the Lower Peninsula, including all or part of the following counties:
• May 16 – 23: Clinton, Genesee, Gratiot, Huron, Ingham, Jackson, Lapeer, Lenawee, Livingston, Macomb, Midland, Monroe, Oakland, Sanilac, Shiawassee, St. Clair, Tuscola, Washtenaw and Wayne
• May 17 – 27: Allegan, Barry, Berrien, Branch, Calhoun, Cass, Clinton, Eaton, Gratiot, Hillsdale, Ingham, Ionia, Isabella, Jackson, Kalamazoo, Kent, Lenawee, Mecosta, Montcalm, Muskegon, Newaygo, Oceana, Ottawa, St. Joseph, and Van Buren
• May 18 – June 3: Alcona, Alpena, Antrim, Arenac, Bay, Benzie, Charlevoix, Cheboygan, Clare, Crawford, Emmet, Gladwin, Grand Traverse, Iosco, Kalkaska, Lake, Leelanau, Manistee, Mason, Midland, Missaukee, Montmorency, Ogemaw, Osceola, Oscoda, Otsego, Presque Isle, Roscommon and Wexford
These patrols are a North American Electrical Reliability Corporation (NERC) requirement for ITC’s vegetation management program, support proactive maintenance objectives, and are in line with the company’s model for operational excellence. They include inspections of all transmission structures and equipment including, but not limited to, monopoles, steel towers, 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.
