Deeds – Ipava (Illinois segment)
345kV Transmission Line Project
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 Deeds – Ipava project
ITC Midwest is proposing the construction of a double circuit 345,000/161,000 volt (345/161 kV) electric transmission line that will begin at the ITC Midwest Deeds Substation in Lee County, Iowa and extend southeast into Illinois. In Illinois, ownership of the 345 kV line will transfer to Ameren Transmission Company of Illinois (ATXI), and the combined ATXI 345 kV and ITC Midwest 161 kV line will proceed to the ITC Midwest Niota Substation in Hancock County, where ITC Midwest’s 161 kV line will connect. From there, Ameren’s 345 kV line will continue east to ATXI’s Ipava Substation. The 345/161 kV line’s proposed route from the Mississippi River to the Niota Substation covers about 3.2 miles.
The Deeds – Ipava 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
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.
Landowners are compensated for permitting ITC Midwest to secure an easement on their property. ITC Midwest understands and appreciates the impact that line construction has on landowners and pledges to treat all landowners with the utmost respect during this important process.
