The power line that American Transmission Co. plans to build across Dane County is pegged to cost about $215.2 million, ATC spokeswoman Sarah Justus said.
The project was slated to cost $214 million, but several changes made by the commission — including requiring shorter towers near the University of Wisconsin-Madison Arboretum and landscaping and other transmission changes near the Odana Hills Golf Course — added about $1.2 million to the project cost.
