PROJECT PROFILE: Ledyard-Colby 345 kV Electric Transmission Project Reliable, sustainable, efficient energy is critical to the quality of life we enjoy. To improve electric reliability, enable more electric generating sources to connect to customers, and meet the region’s growing energy needs, ITC Midwest (ITC) is preparing to build a new high-voltage electric transmission line in north central Iowa. The Ledyard-Colby 345,000-volt (345 kV) line is part of a network of new 345 kV transmission lines planned by ITC and MidAmerican Energy to serve the region. This new ITC line will run approximately 55 miles from ITC’s proposed Ledyard substation near Ledyard, Iowa, to a new Colby substation northwest of Mason City. Where possible, ITC is proposing that the line be built on new structures that would also carry existing transmission lines that currently operate in the area. MULTIPLE BENEFITS MISO, the independent transmission organization for the 11-state region that includes Iowa, has studied and designated 17 transmission projects as “Multi-Value Projects” (MVPs). The Ledyard-Colby line is a portion of one of those projects. The MVP transmission lines will bring four major benefits to northern Iowa and the rest of the MISO region: improved reliability, expanded access to generation sources, increased system efficiency, and economic investment. Improve Reliability Because energy is so central to the Midwestern quality of life, residents expect it to be available every moment of the day in every season of the year. The Ledyard-Colby line will strengthen the region’s high-voltage electric transmission system. A stronger transmission system reduces customer service interruptions due to severe weather and allows other lines to be taken out of service for maintenance or unexpected equipment problems without impacting regional service. Expand Generation Options To meet customer energy demands, Midwestern utilities have increasingly turned to wind energy. Connecting those new generating sources to customers requires a strong electric transmission system. The Ledyard-Colby transmission line will improve the ability of electric utilities to access additional sources of generation, including wind generators located in the region. New local generation sources also can lead to additional local jobs, tax payments and landowner payments when wind farms locate in the state. Improve System Efficiency When the electric transmission system is constrained, utilities may need to use more expensive generation rather than lower- cost generating options. That increases the cost of energy to consumers. Completing the Ledyard-Colby line will reduce the inefficiencies that occur because of system bottlenecks. That allows utilities to make greater use of the least expensive electric generating resources already in place.

Ledyard-Colby 345 kV Electric Transmission Project
Reliable, sustainable, efficient energy is critical to the quality of life we enjoy. To improve electric reliability, enable more electric generating sources to connect to customers, and meet the region’s growing energy needs, ITC Midwest (ITC) is preparing to build a new high-voltage electric transmission line in north central Iowa.

Support Jobs and Investment The Ledyard-Colby line will help ensure reliable, efficient and abundant electricity for Midwest communities working to
attract companies and create jobs. This line will provide reliable power to support economic development, employ people
who will build and maintain the line, and increase the property taxes paid by ITC and any new businesses attracted by
reliable energy infrastructure.
AN INVESTMENT IN THE MIDWEST’S FUTURE
Meeting the energy needs of the future requires investment in infrastructure today. By partnering with local officials,
communities and landowners, ITC is helping set the stage for a healthy future for the region.
ABOUT ITC
ITC Holdings Corp. is the nation’s largest independent electricity transmission company. The company’s Midwest
operating company, ITC Midwest, operates more than 6,600 miles of electric transmission lines in Iowa, Minnesota,
Illinois and Missouri, and maintains operating locations at Dubuque, Iowa City, and Perry, Iowa; and Albert Lea and
Lakefield, Minnesota. ITC Midwest is headquartered in Cedar Rapids, Iowa.
FREQUENTLY ASKED QUESTIONS
Q: How big will this line be?
A. The new tubular steel poles will be approximately 100 to 175 feet tall and will be spaced approximately 800 to 1,100 feet apart, varying with terrain and local conditions along the route. The structures will be installed on concrete foundations that are between eight and 12 feet in diameter.
Q: How was this route chosen?
A. The primary factor in determining the line route is the proposed locations of the Ledyard and Colby substations along the line route. To minimize impact on landowners where possible, ITC is proposing to locate the new line in existing transmission line corridors currently in compliance with Iowa Code, placing both lines on opposite sides of new primarily single-pole structures. To determine the appropriate route to connect the substations, ITC carefully considered routes that parallel roads and railway right-of-way or follow along division lines of lands, according to government survey, where practicable and reasonable in accordance with Iowa Code §478.18(2) and Section 11.1(7) of the Iowa Administrative Code.
Q: What is the timing for construction?
A. Construction will depend on the timetable for acquiring landowner easements and obtaining Iowa Utilities Board approval. ITC proposes to start construction in 2016 with projected completion by the end of 2018.
