Beverly-Sub 92

345 kV Transmission Line Project

Beverly – Sub 92 proposed project route

Project Background

Responding to the needs of the changing energy landscape, the Midcontinent Independent System Operator (MISO), the grid planning organization for our region, has devoted several years of an intensive, collaborative effort to develop a Long-Range Transmission Plan – known as LRTP – to build needed high-voltage transmission infrastructure across the region. ITC was actively involved with this process and advocated for the LRTP projects.

The Beverly – Sub 92 project

One segment of the LRTP portfolio is the proposed Beverly – Sub 92 project, that travels through Linn, Johnson and Muscatine counties from ITC Midwest’s Beverly Substation in Cedar Rapids (Linn County) to the Sub 92 Substation owned by MidAmerican Energy, which is located near West Liberty in Muscatine County. ITC Midwest will have sole responsibility for the construction, operation and maintenance of this project.

The proposed route includes constructing a new 345,000 volt (345 kV) transmission line that joins the route of an existing 161 kV transmission line which will be removed and rebuilt in a triple circuit configuration (three circuits on the same structures), including a separately proposed 345 kV transmission line for a portion of the route in Linn and Johnson counties. Altogether through the three counties, the line is approximately 49 miles. The final route may change and will be determined when easement negotiations with landowners are completed and the Iowa Utilities Commission has approved the project.

The Beverly – Sub 92 project will provide numerous benefits and drive value for electric consumers locally and regionally. When completed, this transmission line will:

  • Increase transmission infrastructure to improve system reliability 
  • Enhance grid resilience to better withstand extreme weather
  • Expand access to generation resources for electric consumers by reducing transmission system congestion
  • Improve distribution of lower-cost energy resources, including renewables

FAQs

What is ITC Midwest doing to minimize the impact on landowners and current land uses?

ITC Midwest seeks to minimize the impact of the line on existing land uses. The company is committed to protecting the environment and will fully compensate landowners for any damages that occur during the construction process.

Where possible, this new line will be co-located with existing transmission lines to mitigate the need for a new transmission corridor across privately owned land. To minimize the footprint of the line, ITC Midwest plans to use steel monopoles.

How will ITC Midwest work with landowners?

Under Iowa law, ITC Midwest cannot negotiate for easements until after the Iowa Utilities Commission holds a public information meeting. For this project, public information meetings were held in Cedar Rapids, Tiffin and West Liberty on October 30, 2024.

ITC Midwest representatives are now meeting with affected landowners in the proposed corridor to explain the process and their rights, and ultimately, to begin negotiations to secure voluntary easements. Landowners are compensated for permitting ITC Midwest to secure an easement on their property. ITC Midwest understands and appreciates the impact that new line construction has on landowners and pledges to treat all landowners with the utmost respect during this important process.
