BARABOO, Wis. — U.S. Rep. Tom Tiffany said Friday that he remains firmly opposed to a proposed high-voltage transmission line stretching across southern Wisconsin. “Very simply put, I oppose 765,” Tiffany said during a town hall hosted by Wisconsin Energy Policy in Baraboo. The proposed project would run about 190 miles and carry 765 kilovolts of electricity through parts of nine southern Wisconsin counties. Residents attending the town hall largely echoed Tiffany’s opposition. Democratic candidate David Crowley announced his opposition to the line the previous week, arguing that Wisconsin should examine alternatives that would cause less disruption. One supporter at the event said Gov. Tony Evers should take the lead in addressing the project. The transmission line has become one point of disagreement between Tiffany and Crowley as they outline competing visions for Wisconsin’s energy future. Tiffany said the state would move in a different direction if he becomes governor. “As the next governor, that will not be the future,” Tiffany said. The proposed line’s route, cost, potential effects on landowners and role in meeting Wisconsin’s electricity needs remain central questions as opposition grows among residents and political candidates.
