Wisconsin PSC grants approval for £405m transmission line project
August 22, 2019 – The Wisconsin Public Service Commission (PSC) in the US has given preliminary approval for the construction of the Cardinal-Hickory Creek transmission line project.
Estimated to cost approximately $492m (£405.5m), the Cardinal-Hickory Creek is a 345kV transmission line proposed to run from the Hickory Creek substation in Dubuque County, Iowa, to the Cardinal substation in Dane County, Wisconsin.
The project is a joint venture between American Transmission Company, ITC Midwest, and Dairyland Power.
Wisconsin PSC chairperson Rebecca Cameron Valcq said: “Transmission is the backbone of clean energy alternatives to fossil fuel.
“Getting low-cost, clean energy from where it is plentiful in the west to where it is needed, and at the scale that it is needed, cannot be done without building transmission infrastructure.
“I support this project because I firmly believe that it will provide tangible economic and reliability benefits to Wisconsin customers, and will serve as the cornerstone to achieving a zero carbon future.”
The project partners are planning to commence construction in October 2020 with the line scheduled for commissioning by December 2023.
In addition to supporting the growing renewable energy production area in the Upper Midwest, the line is expected to improve transmission system reliability, and increase transfer capability between Wisconsin and the west.
The project is also expected to reduce CO2 emissions by supporting the interconnection of up to 8.4GW of new generation.
Non-profit organisation Clean Grid Alliance executive director Beth Soholt said: “The demand for more renewable energy is palpable and the Cardinal-Hickory Creek transmission line will provide the ability to access and deliver renewables.
“We are grateful to the Commission for recognizing that more transmission is necessary in order to deliver the clean energy future everyone wants. Cardinal-Hickory Creek will also strengthen the grid and provide congestion relief for an efficient energy market in Wisconsin and the surrounding states.”
