Taft continues to be a key player in supporting the Midwest’s growing transmission needs, guiding complex energy projects through every phase—no matter how long the process takes. From helping Minnesota Power secure approvals for a $1 billion high-voltage, direct-current (HVDC) project to assisting ITC Midwest with the decade-long Cardinal-Hickory Creek 345 kV Transmission Project, Taft’s expertise is driving critical energy infrastructure forward. These projects underscore Taft’s commitment to enhancing grid reliability, fostering renewable energy integration, and ensuring the Midwest is prepared for a clean energy future.

Minnesota Power’s HVDC Transmission Project

In a milestone achievement on October 25, Minnesota Power’s HVDC modernization project received the Minnesota Public Utilities Commission’s (Commission) written order for both the Certificate of Need and Route Permit. This $1 billion project aims to modernize aging infrastructure to benefit Minnesota Power’s customers, positioning Minnesota Power for a cleaner energy future.

Taft played a central role in this success. Represented by Kodi Verhalen, Valerie Herring, and Peter Madsen, Minnesota Power navigated a nearly 20-month regulatory process that included pre-application filings and approvals, multiple expert witnesses, and over 2,000 pages of pre-filed testimony. Taft’s team successfully addressed every issue before the Commission, ensuring that the project’s need and configuration were fully supported by the record and would provide the greatest benefits to Minnesota Power customers.

The project involves modernizing infrastructure on each end of Minnesota Power’s 465-mile, ±250 kilovolt (kV) HVDC transmission line that runs from Center, North Dakota, to Hermantown, Minnesota. The equipment to be modernized was placed in service in the 1970s and has operated far beyond its initial estimated operating life – resulting in more frequent HVDC system outages in recent years. The HVDC system delivers more than 500 megawatts of wind energy, is crucial for the efficient transmission of power over long distances, playing a key role in Minnesota Power’s clean energy goals. With the support of Taft, Minnesota Power secured critical funding and regulatory approvals.

The project also benefits from $50 million in U.S. Department of Energy funding and $25 million in state funding to mitigate rate impacts for customers while modernizing the grid. The $25 million in funding for this project is provided by a grant from the Minnesota Department of Commerce and appropriated from the Minnesota State Legislature in 2023. This modernization project will expand the operational capacity of the HVDC terminals and support future clean energy transfers as part of Minnesota Power’s strategy for a carbon-free future.

Cardinal-Hickory Creek Transmission Line Project

In a similar testament to Taft’s role in long-term energy infrastructure, Valerie Herring provided representation for the completion of the Cardinal-Hickory Creek 345 kV Transmission Project, which became fully operational on September 27, 2024. This 102-mile, 345 kV line, part of a broader initiative to enhance regional transmission, supports the connection of renewable energy sources to the grid.

The project, led by ITC Midwest, ATC, and Dairyland Power Cooperative, required multiple federal and state approvals. Taft helped obtain a Certificate of Public Convenience and Necessity (CPCN) from the Public Service Commission of Wisconsin for the project and successfully defended the CPCN in state court.

As of June 2024, more than 160 renewable energy projects in Wisconsin, Iowa, and nearby states—representing over 24.5 gigawatts of clean energy—were waiting on the completion of the Cardinal-Hickory Creek 345 kV Transmission Project. These projects, now able to connect to the transmission grid, will help supply millions of homes and businesses with lower-cost renewable energy. The project also supports the region’s transition away from fossil fuels, facilitating the integration of wind, solar, and other renewable energy sources.
