LaSalle Link Project

Ameren Illinois is proposing the LaSalle Link Project to improve energy reliability for local customers in the LaSalle County area. This Project includes the construction of a new 138 kV transmission line to connect the new Corbin substation in Oglesby, Illinois to the existing North Utica substation near North Utica, Illinois. Our goal is to have this new line in service and providing benefits to the local community by the summer of 2025.

Communities in the LaSalle County area are currently supported by two Ameren Illinois 138 kV transmission lines that serve as the backbone for the energy system. Continuing to rely on these transmission sources could, in the event of a failure, result in power limitations or power outages, that result in extended restoration times and community-wide impacts. As we continue to serve, support and invest in our communities, new projects — like the LaSalle Link Project – allow us to continue supporting future energy needs.

The LaSalle Link Project will be complete by summer of 2025.

Ameren Illinois is currently in the public outreach phase. There will be ongoing outreach with stakeholders, landowners and residents, businesses and other community members before, during and after construction. Our schedule currently anticipates construction starting as early as spring 2024.

Ameren performed a detailed study of the energy system supplying the LaSalle County area. The study identified redundancy and reliability concerns and the need for reinforcements to continue providing safe, reliable and environmentally safe energy to our customers. Multiple alternatives were evaluated, and we ultimately selected a plan to construct an additional138,000-volt transmission line in the area. We believe this is the most efficient solution that will increase the resiliency of the local energy system. The LaSalle Link Project meets Ameren's reliability standards and provides the long-term capability to meet the energy demands of our local communities.

The total investment, including line and substation upgrades, is currently estimated to cost $31 million.

We anticipate using galvanized steel monopole structures. The structures will range between 80- 120 feet tall, depending on terrain. We estimate 7-8 structures per mile with an average span range of 700-800 feet between structures. The average steel monopole structures will have drilled pier, concrete foundations with diameters ranging between 6-10 feet and depths ranging from 25-35 feet for most structures, depending on structural loading and soil conditions. The foundations will have a 2 feet projection from grade. The conductors will meet or exceed the minimum clearance of 21 feet to grade required by the National Electrical Safety Code (NESC).

Currently, there are existing Ameren transmission corridors in the Lasalle County area that may provide an opportunity to co-locate lines along the same corridor or combine transmission lines onto one set of larger steel structures. During the routing process as we gather stakeholder feedback, consult with agencies and apply technical guidelines, we will further determine the final route structure design including size and number of arms.

Developing a transmission route is a phased process that involves the collection of information to understand and identify opportunities and sensitivities within Lasalle County. Over a series of public open houses, we'll gather data about the project area and begin to narrow down route corridors through opportunities and sensitivities that meet technical guidelines. During this collaborative process of working with agencies, community members and landowners, Ameren Illinois will develop constructible routes that minimize impacts and identify at least 2 routes that will be filed with the Illinois Commerce Commission (ICC).

After collecting data and input from the community through our public outreach and planning phases, one or more routes will be developed and filed with the Illinois Commerce Commission (ICC) as a part of Ameren Illinois' request for a Certificate of Public Convenience and Necessity (CPCN).

Once a CPCN is granted, it will include details of the ICC approved final route. Ameren Illinois representatives will begin contacting landowners for the purpose of conducting good faith negotiations for an easement for the new line. Details of the Project, what property rights are needed, location of the easement and compensation will be discussed with each landowner. Landowners will receive a one-time easement payment. Payment is made in the form of a check, at the time of or shortly after the time that each landowner provides an executed easement to Ameren Illinois. In most cases, landowners will be offered an advanced payment (by Ameren Illinois at the time of easement payment) for anticipated crop loss and restoration of crop land.

The requested easement width for the LaSalle Link Project will be 100 feet. Access roads to the right-of-way for construction and maintenance at various points along the line often require additional easement agreements, which may be permanent or temporary. Should these be required, landowners will be compensated for any additional usage of their property.

Ameren Illinois is developing the LaSalle Link Project in a collaborative manner with landowners, community officials and agencies to develop constructible routes that minimize impacts. Ameren Illinois will gather and review input from stakeholders prior to filing proposed routes with the Illinois Commerce Commission (ICC).

The public process is meant to engage landowners with our team so that we can learn as much as we can about LaSalle County. During this process, stakeholders and LaSalle County communities can learn about the need and benefits of the project, discuss questions/issues with our project team and provide input on sensitivities and opportunities to help our team improve the routing and siting process. We look forward to the public's input in understanding the project area from the community's perspective. From this invaluable information, our goal is to develop a better overall project.

We expect to submit our petition to the Illinois Commerce Commission (ICC) in fall 2022. Following the ICC’s review, we anticipate a Certificate of Public Convenience and Necessity (CPCN) for the route in early 2023, which will allow us to begin easement acquisition and our final engineering to prepare for construction.

Ameren Illinois will coordinate with various environmental related agencies such as U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, Illinois Department of Natural Resources, State Historic Preservation Office and other local interest groups. We'll be working with these agencies and organizations throughout the development of the LaSalle Link Project.

Ameren Illinois uses an avian-safe structure design and flight diverters where necessary as part of our corporate Avian Protection Plan to minimize impacts to migratory birds and meet regulatory requirements.
