The 125 mile, 345 kv line would connect northeastern Iowa and western Wisconsin, helping to improve reliability in the local area and the region. The line will work in combination with other Multi-Value Projects in the region, with the added transmission capacity aiding new renewable energy projects in connecting to the electric grid.
The line will begin at the new Hickory Creek substation in Dubuque County, Iowa and would then travel to east to connect with the Cardinal substation in southwestern Wisconsin.
The developers are currently engaged in public outreach efforts, and plan to file applications with state regulators as early as 2018. They anticipate construction to begin in 2019 or 2020, with the line going into service in 2023.
In both Wisconsin, the developer must file for a Certificate of Public Convenience and Necessity from the Wisconsin Public Service Commission (PSC). The developer plans to file with the PSC some time in 2016. Applications with Iowa regulators will likely follow the filings in Wisconsin.
Additionally, the project will have to seek federal approval with the US Fish and Wildlife Service, Rural Utility Service, and the Army Corps of Engineers due to the project crossing the Mississippi River.
The USDA Rural Utility Service (RUS) began hosting a series of meetings in Iowa and Wisconsin in late October and early November 2016 to take public comments on the project.

The developers held community meetings in fall 2014 in Wisconsin to provide information about the project and receive input from local communities in the project study area. Concerns range from the visual impact, the possibility of pursuing alternatives to the new transmission, and the effect on rates that new infrastructure could have.
The city council of Dubuque, IA voted to oppose the line, noting that having the project come through Dubuque would violate city code, and claiming that pursuing a route through the city would not be in the public interest.
Project corridors were refined after open house meetings in May 2016. The developers will continue to refine these corridors to produce several routing options.
The Driftless Area Land Conservancy and Environmental Law and Policy Center voiced concerns over possible habitat disruption and the introduction of invasive species that could result from the project.
Clean Energy Potential:
The Cardinal-Hickory Creek project will connect to other Multi-Value Projects in Iowa and Wisconsin, providing greater access and capacity for renewable energy in the region.

We all know that clean energy transmission is vitally important to our energy future. It brings economic opportunity to rural areas, enables wind development and improves the reliability of your grid. But to build it properly - to create projects that work best for you and your community - requires your knowledge and participation. That's why we've created this database.
