O.k., so I was sure that Madison, WI would be home of the first Tesla Supercharger station. Guess I was wrong. Mauston, WI is way ahead of Madison. A Tesla Owner in Milwaukee (islandbayy) took pics of the station. It is just off the hughway behind Culvers.
Follow the link to see the city’s meeting minutes that show detailed plans. The Tesla Supercharger in Mauston is covered on pages 26-34 of the .pdf.
