FOR IMMEDIATE RELEASE

ITC Conducting Aerial Patrols of Transmission Lines in Southeastern Michigan

NOVI, Mich. May 15, 2014 – ITC will be conducting its semi-annual aerial patrols of
high-voltage transmission towers and lines in southeastern Michigan from approximately
May 22 to May 30, 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 in southeast Michigan will cover the area from Lansing, south to the
Ohio border and east to the Lake St. Clair area, including all or parts of Ingham, Jackson,
Hillsdale, Lenawee, Washtenaw, Livingston, Oakland, Macomb, St. Clair, Wayne and
Monroe counties.

These twice-a-year patrols are a North American Electrical Reliability Corporation
(NERC) requirement for ITC’s operations, maintenance and vegetation management
functions and are in line with ITC’s model for operational excellence. They include
inspections of 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. The flights began in western Michigan on May 12 and will cover nearly
all of the Lower Peninsula, concluding in northern Michigan approximately June 20.
