ITC will conduct aerial inspections of high-voltage transmission lines, towers, and related equipment across Michigan this fall as part of its ongoing efforts to maintain a safe and reliable power transmission system. The inspections are scheduled from September 8 through November 13, weather permitting, and will cover a large portion of Michigan's Lower Peninsula.
The patrols will be carried out by helicopter and will support the operations of ITCTransmission and Michigan Electric Transmission Company, LLC (METC). These inspections help identify maintenance needs, monitor vegetation growth near power lines, and ensure the continued reliability of the electrical transmission network.
A new feature of this year's program is the use of separate flights for vegetation monitoring and maintenance inspections. This approach allows crews to focus more closely on specific operational needs and helps improve the company's overall management of transmission infrastructure.
The inspection program will cover numerous counties throughout the Lower Peninsula. Flights will occur in stages between September and November, allowing crews to assess thousands of miles of transmission corridors. Areas included in the inspection schedule range from northern counties such as Alpena, Emmet, and Grand Traverse to southern counties including Monroe, Wayne, Hillsdale, and Kalamazoo.
These inspections are an important part of ITC's vegetation management and maintenance programs. The patrols also help the company meet requirements established by the North American Electric Reliability Corporation (NERC), which sets standards designed to support the reliability of the electric grid.
During the flights, inspection crews carefully observe transmission structures and equipment to identify signs of damage, wear, or other issues that may require attention. Crews also monitor vegetation located near transmission corridors, as uncontrolled tree growth and other plant hazards can interfere with power lines and create reliability concerns.
Residents may notice helicopters flying at relatively low altitudes near transmission lines during the inspection period. These low-level flights are a normal part of the process and allow crews to conduct detailed visual assessments of equipment. Inspectors look for concerns such as lightning damage, structural wear, and potential maintenance issues that could affect system performance.
By conducting regular aerial patrols, ITC can identify potential problems before they become larger issues. This proactive approach helps improve system reliability, supports public safety, and ensures that transmission infrastructure continues to operate efficiently. The inspection program reflects the company's commitment to maintaining a dependable electric grid while supporting long-term operational excellence throughout Michigan.
