NOVI – ITC will be conducting aerial patrols of the high-voltage transmission structures and lines in Michigan from approximately May 28-June 26, 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 (METC).

The aerial inspections will cover nearly all of the Lower Peninsula, including all or part of the following counties (date ranges are approximate):

  • May 28-31: Livingston, Macomb, Monroe, Oakland, Washtenaw and Wayne.
  • June 3-10: Bay, Genesee, Gratiot, Huron, Ingham, Isabella, Lapeer, Livingston, Macomb, Midland, Montcalm, Oakland, Saginaw, Sanilac, Shiawassee, St. Clair and Tuscola.
  • June 11-14: Allegan, Barry, Branch, Calhoun, Clinton, Eaton, Hillsdale, Ingham, Jackson, Kalamazoo, Kent, Lenawee, Monroe, Ottawa, Shiawassee, St. Joseph, Van Buren and Washtenaw.
  • June 17-20: Allegan, Clinton, Gratiot, Ionia, Isabella, Kent, Lake, Mason, Mecosta, Midland, Montcalm, Muskegon, Newaygo, Oceana and Ottawa.
  • June 21-26: Alcona, Alpena, Antrim, Arenac, Bay, Charlevoix, Cheboygan, Clare, Crawford, Emmet, Gladwin, Grand Traverse, Iosco, Kalkaska, Lake, Leelanau, Manistee, Mason, Midland, Montmorency, Ogemaw, 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.
